Striding beyond numbness: a non-randomized controlled study of an exercise program for breast cancer patients with chemotherapy-induced peripheral neuropathy

Purpose To investigate the effectiveness of a 13-week combined supervised and home-based exercise program in alleviating the symptoms of chemotherapy-induced peripheral neuropathy (CIPN) in patients with breast cancer (BC). Methods In this non-randomized controlled study, 77 patients with BC selected after applying the inclusion and exclusion criteria were allocated to the intervention ( n = 37) or control ( n = 40) group. Patients in the intervention group underwent a 13-week exercise program consisting of health education and hand and foot exercises combined with aerobic, resistance, and balance training, while those in the control group received usual care. The symptoms of CIPN were assessed at baseline (T0), post-intervention (T1), and 3 months post-intervention (T2). Physical fitness and finger flexibility were assessed at T0 and T1. A generalized estimating equation (GEE) model was used to analyze the repeated measures data. Results The results of GEE showed a significant group effect, indicating significant intergroup differences in the total CIPN score and the dimensions of occurrence, severity, disruption, and frequency (all P
