Changes of Swallowing Function and Oropharyngeal Muscle Mass on Sonography After Comprehensive Swallowing Therapy and Neuromuscular Electrical Stimulation in Stroke Patients With Dysphagia

oral exercises, tongue movement, and compensatory techniques, swallowing maneuvers and food modifications, will be performed by an experienced speech and language therapist during intervention

tongue muscle strengthening and endurance exercises by using 15-min IOPI biofeedback program. The biofeedback will be 50%-60% of maximal strength. (total 1 hour/session for 10 sessions)

"The neuromuscular electrical stimulation (NMES) therapy with VitalStim therapeutic device will be done by one physician who is licensed practitioner and certified in use of the VitalStim device. The placement of 2-channel electrodes is depended on the dysphagic types and the clinical swallowing disorders with for oropharyngeal muscles~(1 hour/session for 10 sessions)"
