Objective: To investigate the effect of aqua therapy resistance exercise on arm volume, pain, and shoulder range of movements in post-mastectomy lymphedema.
Methods: This was a single-blind randomized controlled trial. Fifty eligible breast cancer survivors (median, 10 years after surgery) with lymphedema (median, 21% inter-limb difference) were assigned randomly to group A (n=25) or control group B (n=25). The study group underwent 60 minutes of aqua therapy exercise comprising of warm-up for 10 minutes, 40 minutes of strengthening exercises, and 10 minutes of cooling down, three times a week for 8 weeks. The control group underwent 60 minutes of land-based exercise three times a week for 8 weeks. Arm volume calculated by measuring the arm circumference, shoulder flexion, and abduction range of motion (ROM), and pain using a visual analog scale (VAS) were assessed at baseline and after 8 weeks of treatment.
Results: There was a statistically significant difference in limb volume, shoulder flexion and abduction ROM, and VAS scores in favor of the study group (p<0.001) after 8 weeks of intervention. The mean±standard deviation for limb volume, shoulder flexion, abduction, and pain score were 2,108.71±200.97 mL, 169.68°±4.54°, 150.44°±3.92°, and 3.16±1.1 in the study group and 2,256.41±186.94 mL, 147.36°±5.32°, 131.32°±4.38°, and 5.68±0.94 in the control group, respectively.
Conclusion: Adding aqua therapy resistance exercise to routine physical therapy might be more effective in decreasing the limb volume and pain intensity and improving ROM of the shoulder in postmastectomy lymphedema.
