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.
