LLLT for BCRL: a Randomized, Placebo-controlled Study

Summary

This study is conducted to compare between efficacy of large and small area of low-level laser therapy (LLLT) in treatment of post mastectomy lymphedema. The change of severity of BCRL will be measured by the difference of circumference and skin thickness, detected by ultrasound. The influence on clinical symptoms, such as pain, shoulder mobility and hand function, are also investigated in the study.
