Wearable Biofeedback for Swallowing Disorders Rehabilitation in Stroke and Parkinson Disease

Participants in this intervention complete a standardized behavioral swallowing rehabilitation protocol for 12 weeks with weekly (once per week) treatment sessions in the clinic and 3 days of home practice per week using the i-Phagia sEMG system. The protocol includes oropharyngeal strength training and skill-based practice exercises. For this group, patients use the sensor patch and the software guides them on how to complete the exercises and receive feedback.

Participants in this intervention complete a standardized behavioral swallowing rehabilitation protocol for 12 weeks with weekly (once per week) treatment sessions completed remotely (via telehealth) and 3 days of home practice per week. The protocol includes oropharyngeal strength training and skill-based practice exercises. For this group, patients also use the sensor patch and the software guides them on how to complete the exercises and receive feedback.

Participants in this intervention will complete the same standardized behavioral swallowing rehabilitation protocol and in the same frequency as the sEMG biofeedback intervention groups but WITHOUT a device. That is, they will complete the protocol for 12 weeks with weekly (once per week) treatment sessions completed in-person and 3 days of home practice per week. For this intervention group, patients use a visual analog scale and a timer as feedback tools, as frequently done in clinical practice where sEMG devices are not widely available.
