Primary aim: To determine the impact of LLLT, as compared to wait-list control, on changes in severity of lymphedema.~Secondary aim: To determine the impact of LLLT, as compared to a wait-list control, on lymphedema-related symptom burden (e.g., tightness), functional impairments (e.g., range of motion in jaw and neck), and quality of life.
The purpose of this study is to evaluate the effect of low-level laser treatment (LLLT) on the severity of lymphedema, symptom burden, functional status, and quality of life in HNC survivors.
