Purpose: This study systematically reviewed and meta-analyzed the effects of pelvic floor muscle training (PFMT) on the bowel dysfunction and health-related quality of life (HRQoL) of patients with rectal cancer who have undergone low anterior resection (LAR). Methods: A comprehensive search was conducted across six major databases for studies published until May 2025. Studies that evaluated the effects of PFMT on the bowel dysfunction and HRQoL of patients with rectal cancer who have undergone LAR were included. Pooled effect sizes were estimated using random-effects models, and heterogeneity was assessed using the I2 statistic. Subgroup and sensitivity analyses were used to explore potential sources of heterogeneity. Results: Eighteen randomized controlled trials involving 932 patients were included. Meta-analysis demonstrated that PFMT significantly improved bowel dysfunction compared with standard care (Hedges' g =-0.59, 95 % CI:-0.91 to-0.28). However, PFMT did not significantly reduce the incidence of bowel dysfunction (risk ratio = 0.88, 95 % CI: 0.66 to 1.17) or improve the HRQoL (Hedges' g = 0.08, 95 % CI:-0.15 to 0.30) of LAR patients. Subgroup analysis suggested that three-month PFMT interventions yielded the most consistent improvements. Conclusions: Although PFMT reduces bowel dysfunction, it limitedly affects the incidence and HRQoL of LAR patients. These findings highlight the need for early rehabilitation strategies to support postoperative functional recovery. Future research should explore the optimal intervention timing and integration into postoperative care pathways.
