Abstract

Background: Breast cancer-related lymphedema (BCRL) is a common and disabling complication following mastectomy and axillary lymph node dissection, leading to persistent upper limb swelling, pain, restricted mobility, muscle weakness, and reduced quality of life. Matrix Rhythm Therapy (MaRhyThe®), a biomechanical oscillation-based intervention designed to improve microcirculation and lymphatic flow, has shown therapeutic potential, although evidence in BCRL remains limited.

Objective: To evaluate the effectiveness of Matrix Rhythm Therapy as an adjunct to conventional physiotherapy in improving pain, muscle strength, upper limb mobility, arm circumference, and quality of life in a patient with post-mastectomy upper limb lymphedema.

Methods: A prospective single-case study was conducted in a female patient with unilateral upper limb lymphedema following breast cancer surgery. Outcome measures included the Numeric Pain Rating Scale (NPRS), Manual Muscle Testing (MMT), goniometric assessment of shoulder range of motion, arm circumference measurements at standardized anatomical landmarks, and the Lymphedema Quality of Life Questionnaire (LYMQOL). The patient received Matrix Rhythm Therapy for 45 minutes, three times weekly for four weeks, in addition to conventional lymphedema rehabilitation. Pre- and post-intervention findings were compared descriptively.

Results: Following the intervention, the patient demonstrated reduced pain intensity and arm circumference, improved muscle strength and shoulder mobility, and better quality of life scores. Functional performance during daily activities also improved, indicating enhanced upper limb function.

Conclusion: Matrix Rhythm Therapy may serve as a beneficial adjunct to conventional rehabilitation in managing post-mastectomy upper limb lymphedema. The observed improvements in pain, limb volume, mobility, muscle strength, and quality of life support its clinical potential. Larger controlled studies with long-term follow-up are needed to confirm its efficacy and generalizability.
