Summary

This is a device evaluation study to determine the optimal stimulation characteristics for using vibrotactile stimulation as a sensory triggering device for self retraining in patients with chronic moderate to severe dysphagia. Stimulation characteristics to be tested are frequency of vibration, pressure between the device and the skin, mode of vibration (pulsed or continuous).

Conditions

  • Oropharyngeal Dysphagia

Interventions

DEVICE

Vibrotactile stimulation

Comparison of the effects of different vibratory characteristics on the frequency of swallowing, time of initiation of swallowing with stimulation and urge to swallow. Will compare frequency of vibration, mode of vibration, pressure of device against neck, and duration of vibration. Each session will last no more than 1 hour with short breaks. Each participant can volunteer for up to three nonconsecutive sessions.
