  • Patent number: 10433785
    Abstract: A diagnosis device, and more particularly, a compartment syndrome diagnostic device is described herein. The diagnostic device may include a display that renders information associated with stimulation of a motor unit suspected of suffering from compartment syndrome. The diagnostic device may generate a stimulation signal for stimulating the motor unit through an electrode. The device may determine whether the motor unit is at risk for compartment syndrome based on the response of the motor unit to the stimulation. The diagnostic device may also measure pressure of a compartment. The device may determine whether the motor unit is at risk for compartment syndrome based on the measured pressure and the response of the motor unit to the stimulation.

  • Patent number: 10378937
    Abstract: A method for clustering of transient signals is provided. The method comprises the steps of acquiring the transient signals as they come, dynamically building up clusters of similar transient signals in a hyperspace based on comparison and clustering rules so that each new one of the transient signal acquired ends up in a cluster with similar transient signals formerly acquired, analyzing the clusters to determine respective signatures defined by the transient signals gathered in the clusters, and processing the signatures to detect a phenomenon connectable to an intrinsic attribute of the transient signals.

  • Patent number: 10368793
    Abstract: A nerve integrity monitoring device includes a control module and a physical layer module. The control module is configured to generate a payload request. The payload request (i) requests a data payload from a sensor in a wireless nerve integrity monitoring network, and (ii) indicates whether a stimulation probe device is to generate a stimulation pulse. The physical layer module is configured to (i) wirelessly transmit the payload request to the sensor and the stimulation probe device, or (ii) transmit the payload request to a console interface module. The physical layer module is also configured to, in response to the payload request, (i) receive the data payload from the sensor, and (ii) receive stimulation pulse information from the stimulation probe device. The data payload includes data corresponding to an evoked response of a patient. The evoked response is generated based on the stimulation pulse.

  • Patent number: 10357170
    Abstract: A method, system and apparatus for determining the state of a muscle between a normal non-tired state, a tired state and a passive involuntary tension state. A signal from the muscle is recorded at rest by using an electrode arrangement, where an earth body may prevent the electrodes from picking up signals beyond the extent of the earth body. The frequency content of the signal is determined by spectral analysis, e.g. by computing a moment of the spectrum. A normal frequency content indicates a non-tired muscle state, whereas a low and a high frequency content indicate a tired and a passive involuntary tension muscle state.

  • Patent number: 10349862
    Abstract: An evoked potential monitoring system including a control unit having stimulator circuitry and a probe assembly coupled to the control unit. The probe assembly includes a stimulus probe and a stimulator handpiece selectively coupled to the stimulus probe. The handpiece includes a handle, control circuitry, and a switch. The control circuitry is electrically coupled to the stimulator circuitry. The switch is electrically coupled to the control circuitry and extends to an exterior portion of the handle. In this regard, movement of the switch remotely controls the stimulator circuitry to continuously increment or decrement a stimulation energy level delivered to the stimulus probe over a series of discrete, incremental steps.

  • Patent number: 10292647
    Abstract: A wearable device has a core contraction sensor and a movement sensor which transmits signals to a processor which analyzes the signals. The core contraction signal may determine if the user's core is contracted or relaxed. A video camera on a smart device may be used with the wearable device to record video of a user while data from the sensors on the wearable device are also recorded. The core contraction and movement sensor data may be sent to and viewed on the smart device display together with video of the user performing a movement. The simultaneous viewing of the video and sensor data may provide immediate feedback to the user regarding the timing of core contractions with body movements in an athletic, training, or therapeutic movement to allow the user to modify and improve coordination of core contraction with body movements to improve movement performance and achieve better results.
