The disclosure is direct to a unique system for delivering NMES and/or TENS therapy to one or more portions of a biological structure. In some embodiments, the biological structure includes a limb such as an elbow or knee. In some embodiments, the system includes a flexible panel with an integrated flexible circuit. In some embodiments, the flexible panel is configured to couple to and bend with a garment. In some embodiments, the flexible panel enables the coupling of one or more electrodes. In some embodiments, the flexible panel is removable from the garment which allows for the garment to be washed without exposing flexible panel electrical connections to submersion in a fluid.

A neck-hanging massaging device includes an elastic arm, a first handle, a second handle, an electrode assembly and an electric pulse generating device. The first handle and the second handle are fixedly connected to the two sides of the elastic arm. The electrode assembly is arranged on the elastic arm. The electric pulse generating device is electrically connected with the electrode assembly. The electric pulse generating device is arranged in the first handle.

Provided is a WCD system, including a collection module, a master control module and a defibrillation module; the collection module collects a signal, and has human body motion detection and vibration prompting functions; the master control module has a VF/VT analysis algorithm to analyze the collected signal, and can control a power supply of the defibrillation module; the defibrillation module has the VF/VT analysis algorithm and a defibrillation control function. Through the independent defibrillation module and the independent collection module, the reliability of the system can be improved.

Disclosed are systems and methods that implement a reporting function to capture subjective a subjective health assessment of the patient and to correlate that subjective health assessment with more objective patient parameter data, such as ECG waveforms and the like, in an attempt to identify nuances in the objective patient parameter data that can be used to predict future (or even imminent) adverse health events.

A mask instrument includes a flexible mask and a controller. The flexible mask includes a first flexible layer, a second flexible layer, a plurality of functional layers located between the first flexible layer and the second flexible layer, and a plurality of electrodes electrically connected with the plurality of functional layers. The flexible mask is electrically coupled with the controller via the plurality of electrodes. The second flexible layer comprises at least one hole at a position corresponding to the plurality functional layers, and at least one portion of the plurality of functional layer is exposed out of the second flexible layer from the at least one hole. A method for using the mask instrument is further provided.

Provided are stimulation devices for improving ambulatory activity of a subject in need thereof. The device includes a foot covering for holding two battery-operated tactile actuators on a metatarsal region and an ankle region of the wearer's foot. The foot covering also includes a detachable material for housing and securing the two tactile actuators and a pouch region for holding electronics.

An electrical stimulation training and neuromuscular rehabilitation system including a machine-washable stimulation suit with multiple electrodes to provide controlled stimulation of various muscle groups is provided. The stimulation suit may also include one or more integrated biosensors to provide diagnostic capability in addition to stimulation. The system may also include a software platform executable on a user computing device (such as a tablet) that may facilitate control of the stimulation programs (e.g., intensity level, duration, isolation of individual muscle groups vs. full body stimulation) of one or more stimulation suits by the wearer or a fitness practitioner or trainer and/or that may facilitate intervention by a medical provider through a remote telemedicine platform.
