Study Arms:
- Vibrotactile Stimulation in Dysphagia (Type: None): A Vibrotactile stimulation device will be evaluated in patients with chronic moderate to severe dysphagia for more than 6 months post onset due to stroke or following radiation treatment for head and neck cancer to assess which frequency, mode, pressure characteristics are most helpful in increasing the rate of swallowing, increasing the urge to swallow, assisting with the initiation of swallowing and not affecting discomfort.

Based on this trial design, predict the completion outcome and termination type (if applicable).
