To determine whether an exercise-based intervention was safe and effective for breast cancer survivors
Quasiexperimental
The number of lymphedema symptoms reduced from baseline to the 12-month follow-up visit (2.6 [SD = 2.6] to 1.7 [SD = 2.1], p = .002), but there was no statistically significant reduction in the severity of lymphedema symptoms from baseline to the 12-month follow up visit (p = .58). In addition, there was no difference in arm volume, measured as a percent of interlimb difference, at the 12-month follow-up visit (p = .98). Within this sample, four patients (8%) had new-onset lymphedema at the 12-month measurement and five (19%) had a flare-up of existing lymphedema.
The PAL intervention reduced the number of lymphedema symptoms but not the severity of symptoms experienced by participants. In addition, the intervention did not reduce the limb volume of participants. Participants were able, however, to complete the intervention, which took place mostly in the home setting, making it a feasible intervention for women with breast cancer.
When available, home-based exercise interventions like the ones described here may be beneficial for patients who are motivated to participate in and complete exercises at home. Nurses should assess patients for readiness to participate in a home exercise program and help patients find resources for planning an appropriate home-based program.
