Publication number: 20180085044Abstract: Systems and methods for clinical assessment of balance may include a tilting balance platform further including: an upper platform, a lower platform, and an array of force transducers sandwiched between the upper platform and the lower platform. The systems may also include: a toroidal bladder supporting the lower platform; an air pressure sensor and a control valve connected to the toroidal bladder; an inclinometer that measures tilt information of the balance platform; and a computer that receives a control signal to activate one of: the array of force transducers and the inclinometer. If the array of force transducers is activated, then a clinical test is performed to measure changes to a subject's Center of Pressure on a stabilized balance platform, and if the inclinometer is activated, then another clinical test is performed to measure the tilt information caused by a subject's movements on a de-stabilized balance platform.Type: ApplicationFiled: September 27, 2016Publication date: March 29, 2018Applicant: Diversified Healthcare Development, LLCInventors: Dean G.

Publication number: 20180085045Abstract: A method and system for determining postural balance of the person is provided. The disclosure provides a single limb stance body balance analysis system which will aid medical practitioners to analyze crucial factor for fall risk minimization, injury prevention, fitness and rehabilitation. Skeleton data was captured using Kinect. Two parameters vibration-jitter and force per unit mass (FPUM) are derived for each body part to assess postural stability during SLS. Further, the vibration and force imposed on each joint a first balance score was quantified. A first balance score and a second balance are also calculated by combining vibration index and SLS duration to indicate the postural balance of the person. The vibration index is computed from the vibration profile associated different body segments.Type: ApplicationFiled: March 22, 2017Publication date: March 29, 2018Applicant: Tata Consultancy Services LimitedInventors: Kingshuk CHAKRAVARTY, Aniruddha SINHA, Brojeshwar BHOWMICK, Sanjana SINHA, Abhijit DAS

Publication number: 20180085052Abstract: Methods and apparatus are disclosed for determining the occurrence of a closed or open apnea. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by applying an oscillatory pressure waveform of known frequency to a patient's airway, calculating a complex quantity representing a patient admittance (12) and comparing its value with ranges (14, 16) indicative of open or closed apneas. The method distinguishes open from closed apneas even when the model used to calculate admittance is not based on details of the respiratory apparatus. In addition the patient admittance may be compared with admittance during normal breathing to avoid having to characterize the airway.Type: ApplicationFiled: September 5, 2017Publication date: March 29, 2018Applicant: ResMed LimitedInventors: David John Bassin, John David Oates, Ronald James Huby, Benriah Goeldi
