A method of treating spasticity uses a garment worn on a target anatomy so as to arrange electrodes on an inner surface of the garment contacting the skin of the target anatomy. Using an electronic processor, a spasticity treatment cycle is performed. The spasticity treatment cycle is initiated by providing a human-perceptible prompt to initiate a spastic event, or by triggering the spastic event by applying electrical stimulation to at least a portion of the target anatomy using the electrodes. Thereafter, electromyography (EMG) signals are measured from the target anatomy using the electrodes. One or more spasm regions in the target anatomy are identified based on the EMG signals. Targeted treatment of the one or more spasm regions is performed using neuromuscular electrical stimulation (NMES), or is directed to be performed by displaying a representation of the target anatomy with the one or more spasm regions indicated on the representation.

This bioelectrode-equipped apparatus comprises a fabric structure having, on a base fabric formed from an elastic fabric, an electrode placement region that includes a wiring formed on a surface of the base fabric, a bioelectrode provided to the terminal end of the wiring, and an insulating layer for covering the wiring, wherein the base fabric has a first extension direction exhibiting relatively low extensibility in the electrode placement region and a second extension direction which is different from the first extension direction and which exhibits higher extensibility than the first extension direction, and the wiring is formed along the first extension direction.

In rehabilitation, a stimulation pattern when applied to a body part by a neuromuscular electrical stimulation (NMES) device is effective to cause the body part to perform an intended action. The applying includes increasing a stimulation level at which the stimulation pattern is applied over time and, during the applying, acquiring video of the body part. The body part is monitored during the applying by analysis of the video, and the applying is automatically stopped in response to the monitoring indicating the body part has performed the intended action. The stimulation pattern may be defined as one or more subsets of electrodes of the NMES device and an electrode group stimulation level for each respective subset of electrodes, and the increasing of the stimulation level comprises increasing a scaling factor applied to the electrode group stimulation levels over time.

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.

A method of reducing stimulation signal interference with an electrical monitoring device includes sensing an electrical interference signal at a first location in a body resulting from delivery of an electrical muscle stimulation signal at a second location in the body, and delivering an electrical counter signal to the patient that destructively interferes with the electrical interference signal to prevent interference with the electrical monitoring device.

A peripheral device for regulating neural correlates of arousal and emotion regulation to be worn or held against the body is disclosed. The device can be triggered by either physiological signs or manual intervention and produces cutaneous signals such as vibration or electricity using novel combinations of physiologically reactive frequencies without effort on the part of the user. One embodiment includes combining sensors that measure changes in physiological signals of stress such as speech rate and pitch, galvanic skin response, or heart rate variability, and, using a machine learning algorithm on personalized data, can determine whether these changes are likely to benefit from regulation. If they are outside an idiosyncratic predetermined range, the device produces stimulation and the person will feel regulated if they are touching/wearing the device, or can choose to use the device if it is not currently being touched or worn.
