Abstract

Complex Decongestive Therapy (CDT), the gold standard for lymphedema treatment, fails to demonstrate long-term efficacy. The purpose of this study was to determine the long-term efficacy of low level laser therapy (LLLT) in reducing post-mastectomy lymphedema when used with CDT. The experimental group received LLLT and CDT (n = 7) while control group received sham laser and CDT (n = 7), twice a week for 4 to 8 weeks. Percent arm circumference difference between affected and unaffected limbs was collected over 18 months. Results revealed no statistical difference between both groups at all time periods: 1 (p = 0.902), 2 (p = 0.535), 3 (p = 0.445), 6 (p = 0.095), 12 (p = 0.537) and 18 months (p = 0.4). Further study with a larger sample size may prove more significant for long-term efficacy of LLLT.
