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

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.
