Abstract: A system for combined electromyography (EMG) measurements and stimulation of a target anatomy includes a garment with electrodes. An analog cable connects with the electrodes of the garment. A stimulator inputs electrical energy to the analog cable to deliver transcutaneous electrical stimulation. Stimulator isolation circuitry switches between connecting the stimulator with the analog cable and electrically disconnecting the stimulator from the analog cable. EMG circuitry receives analog EMG signals from the analog cable and forms digitized EMG data. EMG isolation circuitry switches between electrically connecting the EMG circuitry with the analog cable and electrically disconnecting the EMG circuitry from the analog cable. Control circuitry cyclically switches between stimulation and EMG time intervals.

Abstract: A system for electrical stimulation may comprise a plurality of electrodes and a processor. The processor may be configured to: define a region of interest (ROI) for electrode activation via a first subset of the plurality of electrodes; and define a second subset of electrodes, wherein each electrode within the second subset of electrodes are positioned away from the ROI such that the average distance between each electrode and the ROI is maximized. The second group of electrodes may be defined via low-discrepancy sequences or an equidistributed sequence. The plurality of electrodes may be part of a wearable garment or an implantable device. The system may be for muscle stimulation or neural simulation.

Abstract: A device for functional electrical stimulation (FES), neuromuscular electrical stimulation (NMES), and/or in receiving electromyography (EMG) signals includes a sleeve and electrodes. The sleeve is sized and shaped to be worn on a human arm, and comprises a stretchable fabric The electrodes are secured with the sleeve and positioned to contact skin of the human arm when the sleeve is worn on the human arm. An electronic circuit is configured to operate the electrodes. The electronic circuit includes relays connecting the electrodes with a stimulator for performing FES or NMES, and EMG readout circuitry connecting the electrodes with an EMG amplifier. The relays are closed during FES or NMES to connect the stimulator with the electrodes. The relays are open during EMG readout to isolate the stimulator from the EMG amplifier.

Abstract: Disclosed is a muscle stimulation system, comprising a wearable garment including a plurality of electrodes, and a processor; wherein the processor is configured to define one or more regions of interest (ROI) for electrode activation via a subset of the plurality of electrodes, and provide electrical muscle stimulation, via the subset of the plurality of electrodes, to the ROI.

Abstract: A device for functional electrical stimulation (FES), neuromuscular electrical stimulation (NMES), and/or in receiving electromyography (EMG) signals includes a sleeve and electrodes. The sleeve is sized and shaped to be worn on a human arm, and comprises a stretchable fabric The sleeve has a distal end disposed on or adjacent a wrist of the human arm when the sleeve is worn on the human arm and a proximal end opposite from the distal end. The electrodes are secured with the sleeve and positioned to contact skin of the human arm when the sleeve is worn on the human arm. The sleeve may include an inner sleeve contact with the skin and an outer sleeve disposed over the inner sleeve. The inner sleeve has openings in which the electrodes are disposed.
