Effects of matrix rhythm therapy on primary lymphedema: a case report.

[Purpose] Primary lymphedema occurs because of genetic predisposition and developmental insufficiency of the lymphatic system. Matrix Rhythm Therapy was developed as an external and dynamic method that supplies rhythmic mobilization of the fluids in tissues. The aim of the study was to investigate the effects of Matrix Rhythm Therapy in primary lymphedema. [Subject and Methods] A 36-year-old female with left lower limb lymphedema was evaluated. Leg circumference was measured before and at the end of treatment, and 1 and 3 months later. The circumferences were converted to volumetric values. Twenty sessions of Matrix Rhythm Therapy (5 days/week) were applied to the affected leg, spine, and abdominal regions. Patient satisfaction was assessed with the Global Rating of Change scale. [Results] Volumetric values were 1,573.28 ml before treatment, 1,573.13 ml at the end of treatment, 1,516.70 ml 1 month later, and 1,441.61 ml 3 months later. At the end of treatment, the volumetric reduction was not significant; however, when compared with baseline, measurements at 1 and 3 months decreased by 3.59% and 8.36%, respectively. The Global Rating of Change score was 2. [Conclusion] Matrix Rhythm Therapy could not reduce lymphedema when used alone, but long-term treatment may show positive effects.
