Question: Is exercise adherence to pelvic floor muscle strengthening a significant predictor of symptom reduction for women with urinary incontinence?
Answer: The effectiveness of the 4-month PFM strengthening program was influenced by the severity of symptoms and the improvement score of PFM strength instead of exercise adherence. Women who had more significant symptoms of leakage (higher score on the Severity Index at baseline) and who had more improvement of PFM strength showed more improvement of symptoms after PFM strengthening.
