A Pilot Study of ALTENS in Improving Dysphagia Induced by IMRT for Head and Neck Cancers
Study hypothesis: ALTENS techniques, administered within the first 3 months after radiation completion, can improve radiation-induced dysphagia and associated symptoms in head and neck cancer patients. This beneficial effect is mediated by the reduction of chronic inflammatory response of swallowing musculature to radiation, consequently a reduction in muscle fibrosis.
Primary study objective: To evaluate the effectiveness of ALTENS in relieving radiation-induced dysphagia. Eating Assessment Tool (EAT-10) scores will be used for this primary study endpoint.

- Change in Subjective Dysphagia Assessment Score: EAT-10 from baseline [ Time Frame: 3 months after treatment completion ] [ Designated as safety issue: No ]EAT-10 is a self-administered questionnaire for subjective assessment of dysphagia. It consists of 10 items and each item is scored using a 5-point Likert scale. The higher the point, the more severe the problem being scored. Normative data suggested that a total score of 3 or higher is abnormal.
- Change in M. D. Anderson dysphagia inventory from baseline [ Time Frame: 3 months after treatment completion ] [ Designated as safety issue: No ]M. D. Anderson dysphagia inventory (MDADI) is a self-administered questionnaire designed specifically to assess the quality of life for head and neck cancer patients who suffer from dysphagia. It incorporated three domains: emotional, functional and physical, and one global question. There are a total of 20 items.Each item is scored on a scale of 1 to 5 with 1 being strongly agree and 5 strongly disagree except for two items, one on the emotional subscale and the other on the functional subscale. The global question is scored and interpreted separately. The scores of all the items in each domain are summed and a mean score is calculated. The final score for each subscale is calculated by multiplying the calculated mean score by 20 with a final range from 0 to 100. The final score of the global question is also calculated in the same way. The higher the final score represents better functioning and quality of life.
