Further, some features may be exaggerated to show details of particular components.
The figures constitute a part of this specification and include illustrative embodiments of the present invention and illustrate various objects and features thereof. Further, the figures are not necessarily to scale, some features may be exaggerated to show details of particular components.

Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
As used herein, “deep breathing difference” or “DBD” refers to a heart rate change achieved by deep breathing, which can be expressed as the mean of the differences between the maximal and minimal heart rate in, for example, six respiratory cycles.
As used herein, a “respiratory cycle” refers to the events that occur during one breath; i.e., inhalation+exhalation=1 respiratory cycle.
As used herein, the “standard deviation of the normal-to-normal intervals” (SDNN), refers to the square root of variance. Since variance is mathematically equal to total power of spectral analysis, SDNN reflects all the cyclic components responsible for variability in the period of recording. SDNN can be calculated over a 24-hour period and thus encompasses short-term HT variations as well as the lowest-frequency components seen in a 24-hour period.
As used herein, “Heart rate variability” refers to variations of both instantaneous heart rate and RR intervals (i.e., R wave to R wave interval).
As used herein, “instantaneous heart rate” refers to a measurement of the distance between the RR interval on an electrocardiogram (ECG) recording. This value provides the length of one heart beat. The single heart beat then is used to determine the number of heart beats/minute, i.e., instantaneous heart rate.
As used herein, “inter-beat interval” refers to the length of time measured between heart beats.
As used herein, a “parameter” refers to a domain parameter and a frequency parameter.
As used herein, a “Lf/Hf ratio” refers to a parameter derived from the frequency analysis of the instantaneous heart rate signal, where low frequencies range from 0.015-0.15 Hz and high frequencies range from 0.15-0.4 Hz.
As used herein, the “pnn50 parameter” refers to the ratio between the number of instantaneous heart beats with a value equal or higher than 50 ms and the total number of heart beats (i.e., number of instantaneous heart beats with a value equal or higher than 50 ms:total number of heart beats).
As used herein, a device is referred to as being “associated” with a user when the device is positioned at a distance from the user that permits the obtaining and recording of the user's heart rate via the device.
As used herein, “wellbeing” and “wellbeing goals” refer to stress goals, focus goals, and any other goals which typically characterize health.
In some embodiments of the system of the present invention, by monitoring variables extracted from the user's Heart Rate Variability (HRV) and other parameters from the heart rate, in real time, the described system is configured to provide recommendations including adjustments to the breathing rate and/or breathing pattern that will increase the efficiency of the breathing exercise. In some embodiments, once the recommendations are practiced by a user, the breathing exercise becomes personalized and adapted to each individual. The breathing power is the ratio, on the HRV power spectrum, between the power around (±10%) the user's breathing frequency and the total power on the spectrum, where the breathing frequency is determined from the frequency with a higher power in the range of 0.1-0.4 Hz.
In some embodiments, the system is based on the premise that HRV decreases under situations of stress either emotional or physical whereas it increases with rest. HRV may be considered a noninvasive marker of autonomic nervous system function and is used for the diagnosis of diabetic neuropathy. In addition low HRV has prognostic value in patients with myocardial infarction and is associated with risks of cardiac events and sudden deaths. HRV is used for the diagnosis as well as for the prognosis of many diseases. The system utilizes HRV and modifying HRV with a personalized breathing program, whereas the inputs can be recorded using a mobile phone, e.g., by using the mobile camera, by Bluetooth, or a compatible heart rate monitor with a sufficiently high sampling rate.
In some embodiments, relaxation can be achieved by a steady and personalized breathing rate. The steady breathing rate may have a pattern of specific timing to inhale, specific length of time to hold the breath and a specific time to exhale breathing, where a pattern is the relationship between inhaling, exhaling, and stopped breathing, which changes from person to person, and can be dependent on the person's situation (e.g., posture, emotional stress, etc.). The same principle applies to focus, where the breathing pattern of inhale and exhale is intended to increase mental focus. The system includes an algorithm configured to evaluate a person's breathing and selects an efficient manner of breathing to achieve stress reduction (e.g., relaxation) and/or focus enhancement and implements the selected breathing manner during a session, i.e., breathing training. In a non-limiting example, the system includes (1) a biofeedback screen configured to provide breathing training to a user, and (2) a panel configured to show the breathing guide to a user. The screen can further be configured to include a moving color progress ball to show a user when to breath in (e.g., the uphill), when to hold the breath (e.g., the plateau) and when to release (e.g., when the ball is on the slope). The system can further be configured to provide a plurality of images, where the plurality of images can include different types of “cones” which represent different types of breathing patterns. As a non-limiting example, a cone without a plateau reflects a breathing pattern of breathing in and out only (without a hold), and is illustrated in
The system of the present invention is configured to allow a user to optimize his breathing pattern so as to result in maximizing the exercise efficiency. The optimization is performed by comparing (i) the current breathing guide and (ii) the variation of the instantaneous heart rate during a breathing cycle. If the instantaneous heart rate consistently lags behind the breathing guide, it will slow down. Alternatively, if the instantaneous heart rate consistently tends to oscillate faster (i.e., where the breathing guide thus lags behind the instantaneous heart rate), then the breathing guide will increase its speed. The conscious breathing pattern induces a regulatory effect on the heart rate and simultaneously the user's personal rhythm will induce a feedback control mechanism on the breathing guide. The breathing guide optimization algorithm stabilizes when the breathing guide and instantaneous heart rate are synchronous.
SDNN [ms] Standard deviation of all RR intervals
SDANNi [ms]—Mean value of all standard deviations of all RR intervals for five-minute segments
rMSSD [ms]—Root of the median squares of differences in successive RR intervals
pNN50 [%] VK [%]—Percentage of successive RR intervals which are >50 ms
Standard deviation×100/mean value of all RR intervals
In some embodiments, the system of the present invention is configured to include three main data flows, where a data flow can be a general stress check. Under the stress check setting, the user is instructed to sit in a relaxed position for approximately 2 minutes while data is acquired. Data can be acquired via, e.g., a wearable device such as, but not limited to, a Bluetooth connected wristband with heart rate data sampling, or by the user's fingers residing on the phone camera and flash and creating the ability for a PPG sampling (as described herein). The stress percentage computation calculation is performed by calculating the HRV features computation by (1) deriving the Lf/Hf ratio of the user, (2) deriving the standard deviation of successive instantaneous heart rate (SDNN) parameter of the user, and (3) monitoring the user's heart rate. The stress percentage is a function derived from these three parameters by assigning different weights on the parameters, to derive at a stress percentage in the range of 0% to 100%. (e.g., but not limited to, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, etc.). The stress percentage is a weighted sum between the normalized Heart Rate, normalized Lf/Hf ratio, normalized SDNN, normalized pnn50 and normalized breathing power, where the normalization is a linear regression that projects a calculated value into a 0-100% scale (e.g., but not limited to, 0.1, 0.2, 0.3, 0.4, 0.5, etc.) The Lf/Hf ratio is a parameter derived from the frequency analysis of the instantaneous heart rate signal, where low frequencies range from 0.015-0.15 Hz and high frequencies range from 0.15-0.4 Hz. The pnn50 parameter is the ratio between the number of instantaneous heart beats with a value equal or higher than 50 ms and the total number of heart beats (i.e., number of instantaneous heart beats with a value equal or higher than 50 ms:total number of heart beats).
In some embodiments, under both the relax and focus biofeedback mechanisms, there is an iterative loop that creates a personalized regimen which is built on the premise that when one inhales rapidly, heart rate speeds, and when one exhales, hearts slows. The heart rate can be synced with breathing and HRV can increase as a result of these rapid changes in the heart rates.
In some embodiments, the stress measurement is iterative, rather than a direct measurement, as a direct measurement is impossible to measure during breathing exercise. The breathing itself disturbs the low frequency HRV signal and artificially spikes the low frequency HRV signal and thus decreases the system's ability to measure stress. In some embodiments, in the relaxation and focus drill, the present invention includes a derivative formula that assesses stress level by evaluating coherence level, inhale/exhale ratio and heartbeat. In some embodiments, stress is not directly extracted from HRV, but inferred, using a formula, from those other indicators. A non-limiting, illustrative example of a method of calculating the inferred stress level is shown in
In some embodiments, in terms of sampling rates, the camera takes about 30 samples a seconds (varies from phone to phone on android). In some embodiments, the system may use at least one filter, e.g., but not limited to a butterworth filter and/or a band pass filter, to reduce or remove movement and other noise. The system is configured to detect the peaks based on the derivatives of the signal. For example, the system is configured to evaluate at the positive peaks and determines whether the positive peaks are valid. If the positive peaks are valid, the system is configured to determine that the positive peaks are a valid PPG is the variation of the signal. The system is configured to calculate the time differences and filters for deviations of more than 20% from previous samples (e.g., but not limited to, 25%, 30%, 35%, 40%, 45%, etc.).
Illustrative Applications: Sexual Dysfunction
Erectile dysfunction (ED) is defined as the persistent inability to achieve or maintain penile erection sufficient for satisfactory sexual performance. ED is highly prevalent in modern societies, affecting approximately 15% of men under the age of 60 years. In fact, ED is one of the most common chronic medical disorders in men over 40 years of age. It was estimated that in 2005, 25 million men in the United States experienced some degree of ED. ED interferes with multiple aspects of the individual's personal, social, familial and occupational life, leading collectively to chronic stress, psychiatric manifestations (e.g. phobias, depression, obsessions and anxiety) and an impaired quality of life. Congruently, low quality of life, chronic stress and depression can cause chronic activation of the stress system leading to aggravation of ED through several pathogenic pathways, such as chronic latent body inflammation, endothelial dysfunction and metabolic syndrome. As such, effective stress management could reverse the pathogenetic indices of ED, leading to symptom relief. A variety of stress reliefs can be used to relax and alleviate the impact of sexual dysfunction, for example progressive muscle relaxation and visualized breathing.
ED's influence on the quality of life of men can include: sexual performance (hesitation in initiating physical intimacy), relationships with partners (qualitative change in interactions with partners), sexual imaginings (loss of physical or emotional responses to attractive partners), beliefs about masculinity (loss of sexual function diminishing a man's sense of self), changes in sexual function may create adverse emotional outcomes (i.e., anxiety and depression), or any combination thereof. Sexual dysfunction can correlate with anxiety, physiologically inhibiting sexual arousal.
In some embodiments, the method of the present invention includes the interaction of anxiety and cognitive interference. Specifically, in response to a sexual context, low perceived control over one's arousal leads to an attentional shift away from erotic cues and on to one's own physiological arousal and the negative consequences of erectile nonresponse, thus creating the self-fulfilling feared outcome, namely erectile failure.
Deep and slow breathing (DSB) techniques are widely used in a variety of psychiatric disorders including anxious and depressive syndromes or stress-related disorders. Studies show that combined treatment is more efficacious than phosphodiesterase type 5 inhibitor (“PDE5-I”) use alone on sexual satisfaction. However, most people don't know how to utilize DSB properly.
In some embodiments, interactive stress management using the software tool of the present invention can be effective to reduce the symptoms associated with ED (when used with medication or even without) for ED. In particular, the system could be used to increase the efficacy of medications used for daily use, such as, but not limited to, Cialis, and could be used with medication used prior for sexual intercourse such as Viagra, Levitra, Cialis, Staxyn, Muse, or their generic variants based on Sildenafil, tadalafil, vardenafil etc.
In some embodiments, the method of the present invention includes implementing the method at the time of taking the ED pill. If more than an hour has passed between the time of taking the pill and sex, the user could use the application again before attempting sex.
In some embodiments, when a subject diagnosed with ED uses the inventive method, the subject's symptoms of ED are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.
Illustrative Applications: Anxiety and Panic Disorder
A panic disorder is an anxiety disorder characterized by recurring panic attacks, causing a series of intense episodes of extreme anxiety during panic attacks. It may also include significant behavioral changes lasting at least a month and of ongoing worry about the implications or concern about having other attacks. The latter are called anticipatory attacks (DSM-IVR).
Panic disorder is not the same as agoraphobia (fear of public places), although many afflicted with panic disorder also suffer from agoraphobia. Panic attacks cannot be predicted, and, therefore an individual may become stressed, anxious or worried wondering when the next panic attack will occur. Panic disorder may be differentiated as a medical condition, or chemical imbalance. The DSM-IV-TR describes panic disorder and anxiety differently. Whereas anxiety is preceded by chronic stressors which build to reactions of moderate intensity that can last for days, weeks or months, panic attacks are acute events triggered by a sudden, out-of-the-blue cause: duration is short and symptoms are more intense. Panic attacks can occur in children, as well as adults.
Typical treatment guidelines American Psychiatric Association and the American Medical Association primarily recommend either cognitive-behavioral therapy or one of a variety of psychopharmacological interventions. Some evidence exists supporting the superiority of combined treatment approaches.
Another option is self-help based on principles of cognitive-behavioral therapy. Using a book or a website, a person does the kinds of exercises that would be used in therapy, but they do it on their own, perhaps with some email or phone support from a therapist.
The software can be useful in preventing the prevalence and reducing the severity of the illness. In addition to the use of the software that could be used on a daily basis, one could add daily questionnaires to ask about the lead indicating symptoms (such as morning dryness of the mouth). Changes in the answers will trigger a course of action by the software such as a message to a coach, doctor or a family member, as well as to additional drills, such as a longer relaxation drill. The cognitive behavioral treatment options can be combined to provide an additional treatment. For example, the illustration shows a combination of visualization and interactive relaxation by combining calming messages communicated on the screen with the interactive breathing exercise. Similarly, recorded guided meditation can be combined with the interactive relaxation breathing exercise. Similarly, progressive muscle relaxation (e.g., where rotating body parts are instructed to be tensed and relaxed) could be mixed with the personalized breathing interactive relax drill described wherein. Similar combinations can be used for addressing anxiety, depression and other mental health indications where cognitive behavioral therapy and breathing exercise can be beneficial.
In some embodiments, when a subject diagnosed with anxiety and panic disorder uses the inventive method, the subject's symptoms of anxiety and panic disorder are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.
Illustrative Application: Attention Deficit Hyperactivity Disorder
In some embodiments, deep breathing can be used to reduce symptoms associated with Attention Deficit Hyperactivity Disorder (ADHD). Interactive breathing has the advantage of providing accurate measurement as to the effectiveness of the guided breathing and the accuracy of its conduct. The system of the present invention could be used for relaxation and/or focus. One method of using it with ADHD patients is to have them use the interactive FOCUS breathing drills in the mornings, when they suffer mainly from focus problems, and the interactive RELAXATION drill in the afternoon, when the effect of their ADHD medication fades and side effects of the medication are prevalent.
In some embodiments, a population of people who take short acting methylphenidate or amphetamine experience irritability or depression for an hour as the stimulant wears off. Sometimes this is worse than the individual's behavior before the medication was started. The present system can be used for the subject patients when the stimulant is wearing off.
In some embodiments, when a subject diagnosed with ADHD uses the inventive method, the subject's symptoms of ADHD are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.
Illustrative Application: Diabetes
Stress is a physical and mental reaction to perceived danger. Conditions that seen uncontrollable or require emotional and behavioral change tend to be perceived as a threat. When the body and mind sense a threat, they get ready to either run or fight. Whether the threats real or imagined, the body prepares for survival by turning up some bodily functions while turning others down. In either case, over time these changes are serious and over time are harmful. Excessive stress works against diabetes management by: increasing blood glucose levels (quickly and substantially); inciting strong negative emotions; impairing sound thinking and decision-making; tempting compulsive, poor eating, or any combination thereof. Whether or not a person has diabetes, over time, stress is harmful because it causes so much wear and tear on the body. For example, the heart works faster and harder in preparation for physical action. The increase in pulse and blood pressure causes a strain on the heart, veins and arteries.
In some embodiments, mammals (e.g., but not limited to, humans) under physical or mental stress have elevated glucose levels. In some embodiments, a person's glucose levels go up with mental stress. In some embodiments, a person's glucose level can go down with reduced mental stress. In people with type 2 diabetes, mental stress often raises blood glucose levels. Physical stress, such as illness or injury, can cause higher blood glucose levels in people with either type of diabetes. Interactive Relaxation drills can be used by people with diabetes in order to stabilize and reduce their glucose levels.
As an example, the following are the results of a clinical study conducted with diabetes patients (with A1C above 7%) who were prescribed to conduct the personalized interactive relaxation drills described herein three times a day, along with a healthy diet (which they were educated about before the study as well but did not adhere to). The sugar levels (as measured by A1C) after less than 3 months dropped by an average of 1.75 (18.5%) (see table for data per patient). The results were at significance level of 99%.
In some embodiments, when a subject diagnosed with diabetes uses the inventive method, the subject's symptoms of diabetes (e.g., but not limited to, glucose level) are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.
Illustration Application: Insomnia and Sleep Quality
Insomnia is a typical symptom of stress that responds to daily breathing exercise practice in the form of improved sleep quality. As a result, the described interactive and techniques can be used to treat insomnia. Furthermore, relaxation techniques typically increase the percentage of time during sleep when a patient is in REM (rapid eye movement, the stage of sleep most associates with dreaming) phase, a phase that is linked to creativity in the ensuing day. Additionally, a night following cyclic meditation (CM), the percentage of slow-wave sleep (SWS) is higher than in the night following supine rest (SR), whereas the percentage of REM sleep and the number of awakenings per hour were less. For example, in a study of cancer survivors suffering from sleep disturbances, 410 survivors were accrued (96% female; mean age, 54 years; 75% had breast cancer). Half of the survivors were trained with Yoga for Cancer Survivors program consisting of pranayama (breathing exercises), 16 Gentle Hatha and Restorative yoga asanas (postures), and meditation. Participants attended two 75-minute sessions per week. Participants demonstrated greater improvements in global sleep quality and, secondarily, subjective sleep quality, daytime dysfunction, wake after sleep onset, sleep efficiency, and medication use at post-intervention (all P<0.05) compared with standard care participants.
The system of the present invention includes a method of breathing that is personalized and providing a high efficacy level of relaxation, thereby increasing the REM portion during the sleep, and enhancing sleep quality (as measured by number of times of awaking).
In some embodiments, when a subject diagnosed with insomnia uses the inventive method, the subject's symptoms of insomnia are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.
Illustration Application: Irritable Bowel Syndrome
Stress is a major driver in IBS, and stress reduction techniques using breathing could alleviate the IBS symptoms.
For example, a study was performed where a conventional group (n=12, 1 dropout) was given symptomatic treatment with loperamide 2-6 mg/day for two months, and the yogic intervention group (n=9) consisted of a set of 12 asanas (e.g., yogic poses, i.e., Vajrasana, Shashankasana, Ushtrasana, Marjariasana, Padhastasana, Dhanurasana, Trikonasana in two variations, Pawanmuktasana, and Paschimottanasana) along with Surya Nadi pranayama (right-nostril breathing) two times a day for two months. Two months of both conventional and yogic intervention showed a significant decrease of bowel symptoms and state anxiety. This was accompanied by an increase in electrophysiologically recorded gastric activity in the conventional intervention group and enhanced parasympathetic reactivity, as measured by heart rate parameters, in yogic intervention group.
In some embodiments, a user's following the inventive methods can alleviate the IBS symptoms in a high degree.
In some embodiments, when a subject diagnosed with IBD uses the inventive method, the subject's symptoms of IBD are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.
Illustration Application: Migraines
Personalized interactive relaxation can be used to alleviate the frequency and severity of migraines as well as to reduce the level of medication. For example, seventy-two patients with migraines without aura were randomly assigned to yoga therapy (which included, e.g., deep breathing drills aside from a set of yogic postures) or self-care group for three months. Primary outcomes were headache frequency (e.g., as memorialized by a headache diary), severity of migraine (e.g., as measured by a 0-10 numerical scale) and pain component (e.g., as assessed using a McGill pain questionnaire). Secondary outcomes were anxiety and depression (e.g., as measured using a Hospital anxiety depression scale), and medication score. After adjustment for baseline values, the subjects' complaints related to headache intensity (P<0.001), frequency (P<0.001), pain rating index (P<0.001), affective pain rating index (P<0.001), total pain rating index (P<0.001), anxiety and depression scores (P<0.001), symptomatic medication use (P<0.001) were significantly lower in the yoga group compared to the self-care group.
In some embodiments, when a subject diagnosed with migraines uses the inventive method, the subject's symptoms of migraines are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.
Illustration to PTSD
Tsunami refugees showed dramatic improvement in post-traumatic stress disorder (PTSD) and depression scores after SKY training. In some embodiments, interventions can be used which include interactive relax breathing which has components similar to yoga, viz. SKY and MCYI can be used, providing personalization and measures of breathing effectiveness on reducing trauma driven stress.
In some embodiments, when a subject diagnosed with PTSD uses the inventive method, the subject's symptoms of PTSD are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.
Illustration for Melancholic Depression
The stress reduction techniques can be used to assist in treating mild and severe depression. In some embodiments, electroconvulsive therapy (ECT), imipramine, or SKY can be used with the method of the present invention. In some embodiments, SKY and interactive relaxation can be used to treat mild and melancholic depression in dysthymic and unipolar major depressives. Depressed people have a particular EEG brainwave abnormality, which is measured by P300 event related potential (ERP) amplitude. By day 30, there is significant relief from depression in the groups treated with SKY, as measured by the P300 amplitude and standard depression scales. By day 90, P300 amplitude can return to normal and allow each patient to be stable and depression free, or at least significantly reduced symptoms of instability and/or depression. Personalized interactive relaxation technique operates on similar mechanisms while providing immediate feedback re the effectiveness of the breathing exercise and the providing of personalized regimen.
In some embodiments, when a subject diagnosed with depression uses the inventive method, the subject's symptoms of depression are reduced, e.g., but not limited to, 1%, 5%, 10%, 15%, etc.

Stress is typically linked to the habit of tobacco and alcohol consumption, which in turn leads to disease states. Stress Reduction technique using the methodology described above can be used in order to assist in smoking cessation programs. For example, SKY (a breathing technique) can help to control the tobacco habit in 21% of individuals who were followed up to 6 months of practice. A personalized breathing exercise using the methodology illustrated herein can be used to provide immediate feedback as to the effectiveness of the breathing in reducing the stress level of the patient and the rendering of an effective and dynamic personalized regimen.

Description of Calculating Stress Level when Using Breathing Exercise
In some embodiments, the process begins by placing the finger on the camera and flash and following the instructions (inhaling when the ball is on the left axis, hold breathing when it is on the plateau and exhale on the right side). In some embodiments, the square in the middle is highlighting what is seen by the camera and the red is in fact what the camera sees, which is the illuminated finger skin.
In some embodiments, there is a progress indication (below 36% and on the following screen 74%) shows how much data was acquired thus far in order to provide the initial stress level indication. In some embodiments, with regular phones, it typically takes between 30 seconds to 1 minute.
In some embodiments, after a period where sufficient data is acquire, the system calculates the initial inferred stress level (e.g., see
In some embodiments, an initial inferred stress level is indicated and is being updated in real time, reflecting the changes in the inferred stress level based on how the body responds to the personalized breathing exercise (e.g.,
In some embodiments, whenever the signal quality is insufficient, the system can provide a message of low signal quality, such as
In some embodiments, the indicators of stress level are typically according to the stress level percentages. In the non-limiting example above, the range between 40-50% is relaxed, below 40% is Highly Relaxed and above 50% is Stressed or Elevated Stress.
In a non-limiting example, the stress function calculation includes the following:
In some embodiments, during the Stress Biofeedback exercise the Stress Function is composed by a combination of heart coherence, heart rate minimum and maximum variation and heart rate.
1.1 Coherence
The coherence is a measure of how synchronous the heart rate variation is with the breathing. In some embodiments, the coherence is computed from the heart rate variability power spectrum, by looking at the percentage of the power that falls within the breathing frequency.
The breathing frequency (bf) is computed as:
bf=1/(inhale+hold+exhale)
-
- where inhale, hold, and exhale are expressed in seconds and bf in Hz.
In an exemplary embodiment, Heart Rate Variability−Power Spectrum can be calculated. In some embodiments, the coherence is computed by integrating the area corresponding to the breathing frequency and normalizing it the total power (e.g.,
In some embodiments, the power corresponding to the breathing frequency Pbf is computed on the area surrounding bf, defined as bf±10%, as shown in figure above. In some embodiments, the coherence is finally normalized as:
coherence=Pbf/Ptotal
-
- where Ptotal is the total power (area under the orange curve in figure above. Coherence is thus a normalized value, ranging from 0 to 1.
In some embodiments, the contribution of coherence to the stress function, in percentage, assumes that a coherence of 0 corresponds to 100% stress and a coherence of 0.8 (80% of the total power) corresponds to 0% stress. In some embodiments, this translates to
Pcoherence=−125×coherence+100
The numbers: −125 and 100 are fixed values which correspond to the parameters used in the linearization of the coherence values. The linearization maps each value of coherence into a 0:100 value.
1.2 Variation
In some embodiments, during a breathing cycle, the heart rate increases during inspiration (mediated by the sympathetic nervous system) and decreases during expiration (by the inhibition of the sympathetic nervous system/activation of the parasympathetic nervous system).
In some embodiments, in a healthy young adult the exhale/inhale ratio (E:I) of the maximum/minimum interbeat intervals (time, in seconds, between successive beats), respectively, is known to be at least 1.17 during relaxed breathing. In some embodiments, assuming that a E:I ratio of 1 (no variation) corresponds to 100% stress and a E:I of 1.7 corresponds to 0% stress, the contribution of heart rate variation to the stress function, in percentage, becomes:
PE:I≈−143×E:I+242
The values: −143 and 242 are fixed values which correspond to the parameters used in the linearization of variation values. The linearization maps each value of variation into a 0:100 value.
Heart Rate
In some embodiments, the contribution of the instantaneous heart rate (HR) to the stress function assumes that a resting heart rate of 60 bpm corresponds to 0% stress and a resting heart rate of 110 bpm corresponds to 100% stress. In some embodiments, each new heart rate value is mapped to a percentage of stress as
PHR=2×HR−120
Stress Function
In some embodiments, the global Stress Value is updated, on each iteration, taking into account the previous Stress Value (SV) and the new estimation (Temporary Stress Level). In some embodiments, the Temporary Stress Level (TSL) is computed by linearly combining the 3 independent measures (all of them limited to a [0-100] range) as
TSL=0.4×Pcoherence+0.4×PE:I+0.2×PHR
In some embodiments, the computation of the final Stress Level (SL) suffers a bias that favors lower values along the time. In some embodiments, the bias, and the final SL computation is given by, as a non-limiting example:
SL=TSL×0.5+SV×0.5 if TSL<SV
SL=TSL×0.35+SV×0.65 if TSL>SV
Points System
In some embodiments, the Points system is based on the heart rate variation measure, explained in the previous section. In some embodiments, here, a breathing cycle is defined as an inspiration/hold/expiration as shown by the breathing indicator. In some embodiments, the user is awarded one point every time that the E:I ratio is higher than 1.2, indicating that he successfully followed the breathing guide, inducing a large heart rate variability. In some embodiments, other pointing system could be used, with the principle being that the user is awarded for success.
Personalization of Breathing Pattern
In some embodiments, the diagram below is detailing the closed loop control system.
In some embodiments, basically, the present invention starts with a certain Stress Value which is compared with a reference (our “objective, which is 0% stress). In some embodiments, the difference between the objective and the observed value is fed to the controller, which will adapt the breathing pace. In some embodiments, this new pace will be reflected on the HRV and on the Stress Value, thus closing the loop.
In some embodiments, regarding the controller, it can implement control blocks with different degrees of complexity, for example using convex optimization to find a “f(pace)=stress” function but it can use a simple controller. In a non-limiting example, one could use different pace values and then do small adjustments in the pace in the “direction” (lower/higher) that return a lower stress level. In some embodiments, effectively, this is a simplified version of a Proportional Integrative Derivative (PID) controller.
In some embodiments, one could also alter the breathing curves, for example randomly show the user on the first few times that he uses the app, and then we stick to the one where he gets the lowest stress levels, see, e.g.,
In some embodiments, in this screen you can either press the play button and start the operation (by placing your finger on the back of the phone on its camera and flash). In some embodiments, on the top left you see instructions where the left of the triangle instruct you to inhale and the right part of the triangle instruct you to exhale. In some embodiments, the red dot location guides you what to do, according to its location (inhale or exhale). In some embodiments, the wave on the right part of the screen is the heart rate variability on a rolling basis. In some embodiments, in the middle of the screen, there is a depiction of the Heart rate (HR) and the number of points in the game that the user gained. In some embodiments, there are many games that could be utilized, in the illustration here, the gamification is based on a biofeedback game whereby the user is guided to breath according to a breathing pattern and points are gained wherever an HRV wave is maximized at an inhalation. Points are gained if the user is tracking the instructions correctly (by following the ball).
Some illustrated embodiments are shown in

A Method of Calculating Stress Level from the PPG Signal
The algorithm described herein estimates stress levels based on the deviations of the Heart Rate around normal levels and on the ratio between Low and High frequency components of the HRV.
The problem at hand is the high variance between successive measurements of stress levels, with the system presenting very low consistency across users and measurements.
In order to find the origin of this unwanted variation and a possible solution, the following formulation investigates a) if the acquired RR signal is robust enough and b) if the HRV features are robust enough to guarantee results consistency.
Signalacquisition and Quality
In order to keep the smartphone processor load low, the instantaneous heart rate signal (RR) acquired is not filtered or interpolated.
The following analyses were all performed using the algorithms described before, namely PPG acquisition and processing, RR signal construction and HRV features computation. In this section, the data was acquired with the user sitting in a comfortable position, without moving while watching TV.
The first step on the analysis of signal quality was to implement and test the influence of a linear interpolation algorithm, setting the RR signal to a known, fixed sampling rate. Several sampling rates were tested, namely 2, 5 and 10 Hz.
The influence of the interpolation and filtering steps is theoretically most noticeable on the signal spectrum.
The two spectrums show similarity, showing that frequency derived features will be similar to both signals. Without being bound by theory, the similarity of the two spectrums may be due to the spectrum estimation algorithm, which is robust on the estimation of spectrums from unevenly sampled signals.
Finally,
The results from
This temporal variation is natural and due to the regulatory mechanisms of the Autonomic Nervous System. Due to this permanent regulation, HRV analyses are normally averaged over long temporal windows (typically 5 minutes).
In the problem at hand, it is necessary to find a feature, or combination of features that are 1) directly related to stress levels and 2) exhibit minimum variations over short periods of time.
HRV Features for Short Term Stress Estimation
To determine the features for stress estimation, the following are considered: (1) Design a two part exercise capable to i) actively induce stress on a first phase and ii) promote relaxation on the second phase; (2) determine the HRV features that vary the most with the two considered states; (3) determine the HRV features that have low natural short term variations, and any combination thereof. Regarding point 1) the performed exercise consisted in i) 10 minutes of acquisition with the subject standing while solving Sudoku puzzles, both activities known to induce sympathetic responses via physical and psychological stress. The subject was then asked to ii) sit on a relaxed position on a couch, for 10 minutes, watching TV.
During both phases, the finger was properly placed on the smartphone's camera to ensure low signal noise.
The acquired data was processed and the mean and standard deviations were computed for the two periods of data. Features highly correlated with stress levels must exhibit higher variations on the mean value.
The considered features were the Heart Rate (HR), the High (HF) and Low (LF) frequency components of the HRV, the Lf/Hf ratio, the standard deviation of the RR (SDNN) interval over the considered time window, the minimum (MIN) and maximum (MAX) RR values on the considered time window, the breathing frequency (BR freq), the power associated to the breathing frequency (BR power) and finally, the percentage of RR samples over 50 ms (PNN 50).
The features were computed using a sliding window with 90 seconds (one and a half minutes).
Finally, in order to determine the variation on each feature caused by natural fluctuations, the normalized standard deviation was computed. The normalized standard deviation is obtained by dividing the standard deviation of the feature vector by its mean. The normalization step allows different features to be compared and lower standard deviations mean that the feature has a low tendency to drift or oscillate over low periods of time. The table below summarizes the obtained results. The percentage of variation on the mean value of each feature is marked in ITALICS. All features have relatively high variation, with the exception of the breathing rate. The higher variations are present on the Breathing Power (during relaxation the most evident frequency on the spectrum is the breathing frequency), the Lf/Hf ratio and the SDNN.
Regarding the short term natural fluctuations, the values UNDERLINED show the average normalized standard deviation on the two phases of the exercise. The lower variations are observed on the HR and MIN and MAX values.
Some selected features are those with high italicized values and low underlined values. The selected features for the integration on the algorithm are:
-
- Heart Rate, already present on the algorithm, shows a relatively high difference between stress states and low short term variation.
- The Lf/Hf ratio which is a “standard” feature on stress estimation and already used on the algorithm. Although it has high natural fluctuations, it is highly correlated with stress levels since it reflects the joint activity of the sympathetic and parasympathetic nervous systems.
- The SDNN with large average differences between stress states and low natural fluctuations.
- The breathing power
- ThePNN50
Each of these features is an independent variable on a stress function, multiplied by suitable weights.
The stress function is expressed as: [0.1*lf/hf+0.3*Heart_Rate+0.2*SDNN+0.2*coherence+0.2*pnn50]
The weighted values of Table 1 are calculated using the weights as detailed below:
-
- 0.1=Lf/Hf
- 0.3=heart rate
- 0.2=SDNN
- 0.2=coherence
- 0.2=pnn50
Each feature (e.g., Lf/Hf, heart rate, SDNN, coherence, pnn50) is linearized to obtain a value from 0 to 100. The linearization is a typical fitting to a line in the form y=m*x+b where suitable values for y and x were obtained experimentally and m and b were obtained solving the system of equations. When a new value for x arrives, the equation is solved and returns a y value on that line. If the y value is larger than 100 or smaller than 0 it is set to 100 and 0 respectively. This process is repeated to all features on the stress function.
Heart Rate Variability
The rhythmical contraction of the heart is controlled by a group of specialized cells, the Sinoatrial Node (SAN), positioned on the wall of the heart's right atrium. Although all of the heart's cells have the ability to rhythmically generate action potentials, it is the SAN that initiates each cardiac contraction.
In the absence of any neurohumoral influence (nervous or hormonal) the SAN generates approximately 100-120 action potentials per minute, resulting on an equivalent Heart Rate (HR). However, a resting healthy human is likely to have a slower HR of around 70-80 bpm due to the modulation of the SAN firing rate by the innervations of both sympathetic and parasympathetic branches of the Autonomous Nervous System (ANS).
In addition to the direct neural innervation of the heart, other processes responsible to influence the heart rate include the indirect effect of the sympathetic system through the release of adrenomedullary catecholamines and the fluctuations induced by the respiratory-related mechanical stretch of the SAN.
The chronotropic control of the heart is performed by the ANS. The instantaneous HR is thus considered a manifestation of both the (antagonistic) effects of the parasympathetic and the sympathetic nerves through permanent changes in neurotransmitters levels. During rest, both autonomic divisions are thought to be tonically active with the parasympathetic effects achieving dominance, thus lowering the natural frequency of the pacemaker.
It is clear that the RR (blue line) varies around a mean, representing the fine tuning of the beat-to-beat control mechanisms, this oscillation is partially correlated with the breathing waveform. The natural oscillation in the interval between consecutive heartbeats has received many names, including RR variability, RR tachogram and cycle length variability, but the most commonly accepted term to this phenomenon is HRV.
Several methods for the analysis of HRV are described in the literature, they are commonly divided in Time Domain Methods, including statistical and geometric measures and Frequency Domain Methods. The periodic components of heart variability tend to aggregate around typical frequency bands, three major components are identifiable. The Very Low Frequencies (VLF) in the interval 0.0-0.015 Hz, the Low Frequencies (LF), in the interval 0.015-0.15 Hz and the High Frequencies, 0.15-0.4 Hz. The spectrum of the arterial Blood Pressure variability also exhibits two main frequency bands, highly correlated with the LF and HF components of the HRV. Without being bound by theory, it is believed that in the closed-loop circulatory system, these components correspond to vasomotor activity (LF band) and to the respiratory activity oscillation (HF band).
The two LF and HF HRV frequency bands are thus intimately connected with the activity of the two branches of the ANS. The HF component is a reliable marker of vagal (parasympathetic) activity. Exercises of controlled respiration, cold stimulation of the face, and rotational stimuli have been shown to increase the HF components, conditions that can increase vagal activity.
Origin of the Frequency Components
The frequency components of the HRV described in the previous section, are mainly attributed to the activity of the two branches of the ANS.
Vagus nerve activity can change heart rate substantially within one cardiac cycle, and the chronotropic effects decay almost completely within one cardiac cycle after cessation of vagal activity. A vagal burst has its maximum effect after approximately 0.5 seconds, with a return to baseline within 1 second. A sympathetic burst caused no effect for at least 1 second and its maximum expression was only verified 4 seconds later, followed by a 20 seconds relaxation time. Vagal and sympathetic responses could be characterized by low-pass filters, with an additional delay in the case of the sympathetic system. Vagal filter response was characterized as fast with little delay, with a corner frequency of 0.15 Hz and the sympathetic response as slow, with 1-2 seconds delay and a corner frequency of 0.015 Hz. These filter responses are consistent with the observations in humans, where the sympathetic system modulates the HR in frequencies under 0.15 Hz and parasympathetic system in frequencies between 0-0.5 Hz.
A possible explanation to the difference in the responses of the two systems is related to receptor processes and postsynaptic responses. A delay in the cardiac response to acetylcholine and norepinephrine may arise from processes subsequent to the binding of the agonist to the receptor. The linkage between muscarinic receptor activation and changes in ionic currents is mediated by signaling molecules located largely within the cell membrane, opposed to adrenergic stimulation, which is initiated in the membrane and requires a second-messenger activation (a protein kinase in the cytosol) which eventually sends a signal back to the membrane to change the ionic currents.
The emphasis for the physiological explanation of the different responses is usually placed on the speed of the process that initiates the responses, however, the processes that terminate the responses to the ANS stimuli might provide further answers, in particular the processes responsible for the removal of the released neurotransmitters.
The norepinephrine released by the sympathetic nerve endings is removed from the cardiac tissues much more slowly than the acetylcholine, released from the vagal terminals. As a consequence of the potential harmful effects associated with the slow removal of norepinephrine, the cardiac neural control system might have evolved such that the sympathetic nerves ordinarily release the norepinephrine at a slow rate. Hence, changes in sympathetic neural activity can alter cardiac behavior only slightly from beat to beat. Beatwise control of cardiac function would thus be negligible, regardless of how swiftly the sympathetic nerve impulse is transduced to a change in cardiac performance.
