Effectiveness of Acupuncture-like Transcutaneous Nerve Stimulation (ALTENS) in Improving Dysphagia and Associated Symptoms of Chemotherapy and/or Intensity Modulated Radiation Therapy (IMRT) for Head and Neck Cancers: A Pilot Study

Difficulty in swallowing is a concerning symptom after radiation treatment for some types of head and neck cancers. Swallowing becomes difficult when radiation damage induces inflammation (with swelling and pain) in the inner covering tissues of the throat and muscles that involve in the swallowing process. Currently, supportive measures are used to manage this symptom while waiting for the tissue damages to heal. In some patients, the inflamed muscles develop scar tissues causing long-term swallowing difficulty and narrowing of the swallowing passage. Needle acupuncture may help to reduce tissue inflammation and may lessen the severity of swallowing difficulty. However, needle puncture is often not desired by patients. Acupuncture-like transcutaneous electrical nerve stimulation (ALTENS) is like acupuncture treatment, but the acupuncture points are stimulated with mild electrical stimulation without needles, simplifying treatment delivery. This study is to examine if a pre-selected set of acupuncture points treated using ALTENS can reduce swallowing difficulty. There will be a total of 12 treatments given over 6 to 8 weeks. Changes in severity of swallowing difficult after treatment will be assessed using 2 subjective assessment tools.
