Electromyographic characteristics of pelvic floor muscles in women with stress urinary incontinence following sEMG-assisted biofeedback training and Pilates exercises
Researchers compared the bioelectrical activity of pelvic floor muscles in women with stress urinary incontinence following pelvic floor muscle training with surface electromyographic (sEMG) biofeedback (BF group) vs Pilates exercises (P group). Further, changes in voiding diaries and scores on quality of life questionnaire were compared against baseline values and between the groups. Eighteen women comprised the BF group and participated in pelvic floor muscle training with sEMG biofeedback; 13 women comprised the P group and participated in basic level Pilates workouts. The participants continued the protocols for eight weeks. Training with sEMG biofeedback or Pilates exercises led to no marked improvement in bioelectrical activity of the pelvic floor muscles during contraction illustrating no supremacy of any of the two methods concerning the bioelectrical activity of pelvic floor muscles in patients with stress urinary incontinence. After 8 weeks of sEMG biofeedback training, they observed a reduction in resting bioelectrical activity of pelvic floor muscles and during relaxation after sustained contraction, but only in supine-lying. The groups were comparable regarding the alleviation of urinary incontinence symptoms, whereas the Pilates group showed more notable improvement in the quality of life.
