Effects of breast cancer related lymphedema on hand muscle strength, hand functions and sensory loss of hand

Purpose: In this study, we aimed to investigate clinical features of patients with breast cancer related lymphedema (BCRL) and effects of BCRL on hand muscle strength and function. Materials and Methods: Patients applying to oncologic rehabilitation polyclinic with right hand dominancy were included in the study. Clinical and demographic data of all patients were noted, physical examinations were performed. The presence of shoulder pain was questioned. To determine the hand grip strength Jamar hand dynamometer and to evaluate the tip pinch strength pinchmeter were used. Sensory loss was assessed with Semmes-Weinstein monofilament test, hand volume measurement was made with hand volumeter. Results: Thirty two female patients with mean age 54.5 +/- 11.4 (mean +/- SD) were included in the study. Axillary dissection was performed in all patients. 62.5% of patients received radiotherapy in post-operative period, 96.9% received chemotherapy. 78.1% of patients reported that they had shoulder pain on the affected side. In the right side affected group and the left side affected group, there were no significant differences in grip strengths, hand functions, sensory loss and volumes between right and left hands. The tip pinch strength of the right hand was higher than the left side in the left side affected group. Conclusion: In patients with BCRL, having axillary dissection, receiving chemotherapy and radiotherapy in post-operative period, obesity and shoulder pain are common. Evaluation of patients with BCRL should be made in details, should be versatile and should include questioning shoulder pain and hand evaluation.
