The present invention relates to a system for monitoring a physical movements of a user, the system comprising: a detection unit configured for receiving a signal obtained by a sensor device representative of a sensed bodily activity, calculating a load index value and communicate, e.g. to the user wearing the sensor device, the value of the load index value. The invention also relates to a method for monitoring and evaluating physical movement of a user and providing feedback to the user.

An electrode-equipped band includes a first band section and a second band section extending along a longitudinal direction. The second band section includes a first stretchable section, an electrode, a second stretchable section, a ring member, a fold-back section, and a joining section. The first stretchable section has first stretchability along the longitudinal direction. The electrode is provided on a first surface of the first stretchable section. The second stretchable section overlaps with the first stretchable section on a side of a second surface of the first stretchable section, and has second stretchability that allows greater stretch along the longitudinal direction than the first stretchable section. The ring member is provided at a position corresponding to a band end along the longitudinal direction of the second band section, and may be connected to the first band section.

A wearable device includes a processor and a lower module. The lower module includes a pressure sensor for detecting a mechanical movement of a skin that covers an artery. The mechanical movement of the skin is due to blood flow through the artery. The processor is configured to receive skin movement information from the movement sensor; calculate a pulse front velocity (PFV), which is a velocity of a blood wave as the blood wave passes under the pressure sensor; estimate a pulse wave velocity (PWV) using the PFV; and estimate the blood pressure using the PWV.

In an embodiment a wrist-worn electronic device includes a main body, a wrist strap connected to the main body, wherein the wrist strap is configured to place the main body on a wrist of a target user, a wrist size determining part configured to measure, by using the wrist strap of the wrist-worn electronic device, a use circumference of the wrist-worn electronic device that matches a wrist size of the target user, and determine the wrist size of the target user based on the use circumference of the wrist-worn electronic device, and a blood pressure determining part configured to detect a pulse wave signal of the target user, measure a measured blood pressure of the target user based on the pulse wave signal, and correct the measured blood pressure of the target user based on the wrist size of the target user thereby obtaining a first corrected blood pressure of the target user.

What is disclosed is a system for measurement and analysis of blood pressure of a test subject comprising a blood pressure measuring cuff unit; a waveform analysis subsystem coupled to said blood pressure measuring cuff unit via a network; and wherein said cuff unit acquires a digital pulse pressure waveform from a wrist of the test subject, said digital pulse pressure waveform is transmitted over said network to said waveform analysis subsystem, and said waveform analysis subsystem processes said digital pulse pressure waveform to extract one or more blood pressure parameters and hemodynamic parameters.

A tool for predicting that a person is likely to be abnormally hydrated over a future time interval, and in some cases to alert the person or a medical professional to intervene. From a series of physiological measurements, a tissue electrical impedance spectrum curve, which comprises a phase spectrum curve in an embodiment, is determined and changes in the shape of the curve are ascertained. The measurements may be received using one or more sensors worn by the person. In some embodiments, current and historic spectrum curvature are applied to an evolutionary algorithm, such as particle-swarm optimization (PSO) or differential evolution (DE), to determine an inference regarding the persons future hydration status. In one embodiment, a statistical forecast for the next epoch immediately beyond the present one, is determined.

Wrist-wearable apparatuses that may be removed and used as a chest-applied cardiac device may include two chest electrodes on an inner surface of a strap (or strap regions), as well as two finger or more finger electrodes on the opposite side of the apparatus. The apparatus may be removed from the wrist and placed on a chest of a patient such that two electrodes are spaced at least five centimeters apart and in contact with the chest and held in place with two or more fingers to capture orthogonal cardiac signals that may be synthesized into a conventional 12-lead cardiac signal.

The present disclosure provides methods for diagnosing and determining the disease progression of neurodegenerative disorders in patients using neurophysiological biomarkers.

A device for monitoring a health parameter of a person is disclosed. The device includes a device body, a radio frequency (RF) front-end connected to the device body and including a semiconductor substrate and an antenna array including at least one transmit antenna configured to transmit radio waves below the skin surface of a person and a two-dimensional array of receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves, wherein the semiconductor substrate includes circuits configured to generate signals in response to the received radio waves, and an alignment feature integrated into the device body and configured to align the antenna array with an object.

A therapeutic or diagnostic device comprises a wearable electrodes garment including electrodes disposed to contact skin when the wearable electrodes garment is worn, and an electronic controller operatively connected with the electrodes. The electronic controller is programmed to perform a method including: receiving surface electromyography (EMG) signals via the electrodes and extracting one or more motor unit (MU) action potentials from the surface EMG signals. The method may further include identifying an intended movement based at least on features representing the one or more extracted MU action potentials and delivering functional electrical stimulation (FES) effective to implement the intended movement via the electrodes of the wearable electrodes garment. The method may further include generating a patient performance report based at least on a comparison of features representing the one or more extracted MU action potentials and features representing expected and/or baseline MU action potentials for a known intended movement.
