Prophylactic Swallowing Exercises in Patients With Head and Neck Cancer Undergoing Chemoradiation<subtitle>A Randomized Trial</subtitle><alt-title>Prophylactic Exercises in HNC</alt-title>

Patients who performed prophylactic swallowing exercises had improved swallowing function at 3 and 6 months after CRT but not immediately after CRT or at 9 and 12 months after CRT. The small sample size may have limited our ability to detect significant differences beyond 6 months of observation as well as additional significant differences in our study.
