Summary
Brief summary (as posted)
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.

- Large-area low-level laser therapy
- description
- Large-area low-level laser therapy(Venusure) was administered at proximal forearm, upper arm and axillary region of affected side. The wavelength was 980±15nm, average dose was 10-40nm/cm2 and maximal output was 1000mW. Total treatment duration was 30 min and frequency was 3 sessions/week for 4 weeks.
