Long-Term Effectiveness of Combined Intermittent Pneumatic Compression Plus Low-Level Laser Therapy in Patients with Postmastectomy Lymphedema: A Randomized Controlled Trial.

Background

Upper limb lymphedema may be revealed after breast cancer and its treatment. Among different treatment approaches, intermittent pneumatic compression (IPC) therapy and low-level laser therapy (LLLT) are reported as effective modalities in the treatment of postmastectomy upper limb lymphedema (PML). The aim of the current study is to investigate the long-term effectiveness of combined IPC plus LLLT versus IPC therapy alone in patients with PML. Methods and

Results

The patients were allocated into two groups in this single-blinded, controlled clinical trial. Group I received combined treatment with IPC plus LLLT (n = 21) and group II received only IPC (n = 21). IPC treatment was given 5 sessions per week for 4 weeks (20 sessions). LLLT was also performed 5 sessions per week for 4 weeks (20 sessions). Clinical evaluations were performed before and after the treatment at the 3, 6, and 12-month follow-up visits. According to within-group analysis, statistically significant improvements in the circumference difference (Cdiff) and grip strength were observed in both groups (for Cdiff, p = 0.018 and p = 0.032, respectively; for grip strength, p = 0.001 and p = 0.046, respectively). Visual analog scale values for arm pain and shoulder pain during motion were decreased only in group I.

Conclusion

Both interventions have positive effects on lymphedema, grip strength, and pain. Long-term effects of combined therapy, especially on pain, are slightly superior to the pneumatic compression alone.
