The effectiveness of pelvic floor muscle training on lumbar function and muscle performance in sedentary women with lower back pain: a randomized controlled trial.

Abstract

Objective: This study aimed to investigate the impact of combined core and pelvic floor muscle (PFM) training on lumbar function in sedentary women with lower back pain (LBP).

Methods: This randomized controlled study included 60 female patients divided into three groups: a control group (n = 20), a core training group (n = 20), and a combined PFM and core training group (n = 20). The participants underwent three weekly interventions over four weeks. Trunk muscle endurance, deep lumbar stabilizing muscle activity, and LBP severity were assessed before and after the intervention.

Results: Following the 4-week intervention: 1. In the combined PFM and core training group, significant improvements in muscle endurance (p < 0.01) were observed, particularly in the flexor, extensor, and right abdominal muscles compared to the control group (p < 0.05). 2. In the core training group, significant increases in muscle endurance were seen in various directions (p < 0.05), with highly significant improvements in flexion and right flexion directions (p < 0.01). The flexor muscles exhibited greater endurance than the control group (p < 0.05). 3. In the control group, dorsal muscle endurance significantly decreased after four weeks (p < 0.01). 4. Pain scores after 2 h of sitting significantly decreased (p < 0.01), along with reduced LBP differences (p < 0.05). There was a decrease in pain scores (p < 0.05) and a significant reduction in LBP after 2 h of sitting (p < 0.01).

Conclusion: Core training, either independently or combined with PFM training, can enhance trunk muscle endurance and alleviate LBP in sedentary women with LBP. Core training alone appeared to have a more pronounced effect.
