A joint motion measurement apparatus includes securing mechanisms that secure sensors to various body parts such as the leg, including the femur, tibia, malleoli and/or calcaneus. The sensors are configured to measure a position and/or motion of the various parts of the leg relative to one another. The sensor data is usable to determine kinematic and/or muscle properties of the leg including knee laxity, tibiofemoral measurements and/or spastic properties.

A wearable device includes a housing with a window and an electronic module supported by the housing. The electronic module includes a photoplethysmography sensor, a motion sensor, and a signal processor that processes signals from the motion sensor and signals from the photoplethysmography sensor. The signal processor is configured to remove frequency bands from the photoplethysmography sensor signals that are outside of a range of interest using a band-pass filter to produce pre-conditioned signals, and to further process the pre-conditioned signals using the motion sensor signals to reduce motion artifacts from footsteps during subject running. The device includes non-air light transmissive material in optical communication with the photoplethysmography sensor and the window that serves as a light guide for the photoplethysmography sensor. The window optically exposes the photoplethysmography sensor to a body of a subject wearing the device via the non-air light transmissive material.

Methods and apparatuses for monitoring and regulating physiological states and functions are disclosed. Several embodiments include application of one or more microelectrode arrays to a dorsal root ganglion for measurement of sensory neuron activity, or stimulation of sensory reflex circuits. The methods and apparatuses can be used, for example, for monitoring or controlling bladder function in a patient.

Methods and devices for monitoring and changing the physical orientation of an individual are provided. A method includes providing a wearable device that monitors the physical orientation of an individual, monitoring the physical orientation over time using the wearable device, and issuing an alert from the wearable device to change the physical orientation by a prescribed amount when the individual has maintained the physical orientation for a duration exceeding a maximum length. The wearable device is optionally configured to issue subsequent alerts upon determining that the physical orientation has not changed following the duration. The alerts are optionally of varying natures and issued to, for example, the individual, people nearby, and/or caregivers outside the individual's room.

The present disclosure relates to the field of medicine and discloses a medical therapeutic device for monitoring and treating medical condition of patients. The device comprises an input unit, a plurality of sensors, a control unit, a waveform generator unit, and a coupling means. The input unit receives at least one input from a user. The sensors monitor a plurality of predetermined parameters associated with the health of a patient generate detection signals based on the monitored parameters. The control unit selects a program based on the input and the detection signals. The waveform generator unit generates a therapeutic signal of pre-determined values of at least one of voltage, current, and frequency based on the selected program for facilitating treatment of medical condition corresponding to the selected program.

An action state estimation apparatus is provided that includes a sampling portion, a statistic calculation portion, an action state model storage, and an estimation calculation portion. The sampling portion samples a displacement measurement signal within a predetermined time and generates displacement measurement data. The statistic calculation portion calculates a statistic of the displacement measurement data. The action state model storage stores an action state model modeled by associating the statistic with a loaded state of a muscle of the test subject. The estimation calculation portion estimates the loaded state by setting the statistic as an input vector and using the action state model.

A device for measuring contractions and/or relaxation of one or more muscles of a body cavity, the device having a hollow body which is for positioning in the body cavity and which is covered by a coating made of or having a biocompatible material, the body being formed of two half-shells which are each physically connected, permanently and continuously during the use of the device, with the aid of non-compressible or deformable connecting means, to at least one pressure sensor, or part of the pressure sensor, arranged in the body. Also, a method for measuring the contraction and/or relaxation of the muscles of a body cavity, a method for monitoring the contractions and/or relaxation of the muscles, and a method for exercising these muscles.

The present disclosure relates to a method for detecting and/or quantitatively assessing cardiac dyssynchrony of a subject based on at least one medical imaging scan showing at least part of the myocardium of the subject’s heart, in particular mechanical cardiac dyssynchrony. The medical imaging scan may provide a plurality of values of a predefined myocardial deformation parameter of said part of the myocardium. In a preferred embodiment the method comprises the steps of 1) determining a myocardial deformation deviation between pairs of myocardial deformation parameter values selected from the myocardium of substantially opposite parts of a cardiac chamber, and 2) calculating the cardiac dyssynchrony of the subject based on said myocardial deformation deviation.

A method for controlling a limb of a virtual avatar by the myoelectric activities of a limb of an individual. The method includes a first step of calibrating and second step of moving the limb of the virtual avatar. Also, a system suitable for implementing the method for controlling a limb of a virtual avatar by the myoelectric activities of a limb of an individual.

An intraoral stimulation device configured to be positioned in a mouth of a patient. The device includes a sensor and one or more electrodes. The sensor is configured to monitor a position of the tongue and/or force exerted by the tongue against the sensor and to transmit a signal encoding tongue information. The electrode(s) is/are configured to deliver electrical stimuli to the patient's hard palate when the tongue information indicates that the tongue has moved from a desired position to an undesired position in the mouth. The electrical stimuli causes the tongue to move from the undesired position to the desired position.
