Devices and methods for providing interactivity during a swallowing exercise are disclosed. Sensory guidance is presented to guide a user through a set of swallows to be completed by the user during the swallowing exercise. Signals are received from a sensor device worn by the user, the signals representing surface electromyography data obtained when the user performs the swallowing exercise. Sensory feedback of the user's exertion level is presented, the feedback generated from the electromyography data and updated as further electromyography data is received from the sensor device, wherein the sensory feedback is presented in association with an exertion level calibrated to the user's ability.

Systems and methods for diagnosis and treatment of swallowing disorders with gamification

The development of stretchable, mechanically and electrically robust interconnects by printing an elastic, silver-based composite ink onto stretchable fabric. Such interconnects can have conductivity of 3000-4000 S/cm and are durable under cyclic stretching. In serpentine shape, the fabric-based conductor is enhanced in electrical durability. Resistance increases only ˜5 times when cyclically stretched over a thousand times from zero to 30% strain at a rate of 4% strain per second due to the ink permeating the textile structure. The textile fibers are 'wetted' with composite ink to form a conductive, stretchable cladding of the silver particles. The e-textile can realize a fully printed, double-sided electronic system of sensor-textile-interconnect integration. The double-sided e-textile can be used for a surface electromyography (sEMG) system to monitor muscles activities, an electroencephalography (EEG) system to record brain waves, and the like.

A system is provided for monitoring patients with dysphagia, or swallowing impairments, that monitors muscle movement during intensive swallowing exercises to provide adjuvant visual feedback from surface electromyography.
