A non-contact muscle signal sensing and assisting device, comprises a radar sensing module, a microprocessor and an electrical stimulation module. The radar sensing module continuously transmits a first microwave signal to a muscle bundle part and receives a corresponding reflected muscle signal, and performs a demodulation procedure on a second microwave signal and the reflected muscle signal to obtain and output a demodulated muscle signal. The microprocessor performs a muscle-movement signal characteristic processing procedure on the demodulated muscle signal to obtain a characterized muscle signal. The microprocessor obtains a muscle movement parameter according to the characterized muscle signal and controls the electrical stimulation module to emit a micro electrical stimulation signal to stimulate a reflex nerve when the muscle movement parameter fits an assistive condition, thereby stimulate muscle movement.

A device for influencing a patient's gait, comprising at least one foot lifter stimulation electrode for activating a foot lifter muscle, at least one sensor unit, at least one hip flexor stimulation electrode for activating a hip flexor muscle, and at least one control unit which is coupled to the sensor unit and the stimulation electrodes, processes sensor values from the sensor unit and, depending on the sensor values, activates at least one of the stimulation electrodes.

This disclosure describes various aspects of a unique therapeutic does for an NMES system. In some embodiments, the system includes one or more electrodes and one or more controls that execute a therapy session program. The therapy session program causes the controller to implement a pulse to the one or more electrodes that, when viewed on a graph of amplitude vs. time, create a “chair” shape with an exponentially decreasing amplitude. In some embodiments, the pulse is considerably longer (e.g., 5 ms) than those implemented in the past (e.g., 300 μs). In some embodiments, the pulse is held at a non-zero amplitude after an exponential decrease for a period of time before a non-electrical relaxation time period is implemented by the one or more controllers.

Wearable devices for providing therapy to a patient may include disposable or reusable treatment pads. The treatment pads may include electrodes and are configured to apply energy to various regions around the head and eyes. The treatment pads may provide therapy when the eyes are open or closed. The wearable device may include a battery and/or control circuitry for issuing therapy pulses through the electrodes.

A treatment for obstructive sleep apnea (“OSA”) of a user includes affixing a patch externally on a dermis of the user, the patch including a flexible substrate, an adhesive on a first side adapted to adhere to the dermis of the user, a processor directly coupled to the substrate, and electrodes directly coupled to the substrate. The treatment includes detecting an occurrence of OSA and activating the patch in response to the detecting, the activating including generating an electrical stimuli via the electrodes to activate the genioglossus muscle of the user.

Devices, systems and methods are described for providing muscle contraction stimulation therapy to treat myriad diseases, including heart failure, Type 2 diabetes, and peripheral vascular disease using a skin patch or implantable stimulator that includes a multiplicity of electrodes, a processor, a stimulation circuit, one or more sensors and programming for a patient interface unit, wherein the processor is programmed to control selection of a subset of the multiplicity of electrodes and of operation of the stimulation circuit responsive to an indication of an adverse physiologic response.
