Pelvic floor muscle training for urinary incontinence in female stroke patients: a randomized,controlled and blinded trial

Abstract

Objective:

To examine the effects of pelvic floor muscle training (PFMT) on the contractility of pelvic floor muscle and lower urinary tract symptoms in female stroke patients.

Design:

Randomized, single-blind controlled study.

Setting:

Outpatient rehabilitation hospital.

Subjects:

Thirty one female patients who were more than three months post-stroke and stress urinary incontinence.

Interventions:

The subjects were randomized to either a PFMT group (n = 16), or a control group (n = 15). Both groups received general rehabilitation exercise for 6 weeks, but the PFMT group additionally received PFMT for 6 weeks.

Main measures:

Vaginal function test using a perineometer (maximal vaginal squeeze pressure) and intra-vaginal electromyography (activity of pelvic floor muscle), and urinary symptoms and quality of life using a Bristol Female Lower Urinary Tract Symptom questionnaire.

Results:

After intervention, the maximal vaginal squeeze pressures for the PFMT and control groups were 18.35 (5.24) and 8.46 (3.50) mmHg, respectively. And the activities of pelvic floor muscle of the PFMT and control groups was 12.09 (2.24) ㎶ and 9.33 (3.40) ㎶, respectively. After intervention, the changes of scores for inconvenience in the activity of daily living of the PFMT and control groups were −15.00 (6.25) and −0.17 (1.59), respectively. In addition, the changes of score for lower urinary tract symptom was improved more in the PFMT group (-4.17 (4.00)) than in the control group (-0.25 (1.29)) (P < 0.05).

Conclusions:

These findings suggest that PFMT is beneficial for the management of urinary incontinence in female stroke patients.
