Effectiveness of pelvic floor muscle exercise therapy supplemented with a health education program to promote long-term adherence among women with urinary incontinence

Aims: A longitudinal randomized controlled trial (RCT) was conducted to evaluate the effectiveness of physiotherapeutic pelvic floor muscle exercise (PFME) therapy supplemented with a health education program to promote long-term adherence among women with stress, mixed, and urge urinary incontinence (UI). Methods: Women (n = 129) were evaluated by their general practitioner (GP) and randomized in either the control group (PFME therapy alone) or one of the three experimental groups (PFME therapy with one of the three health education program versions). Therapy consisted of 9-18 individual 30 min sessions with a specialized physiotherapist, over 14-22 weeks. Outcome measures were weekly frequency of wet episodes and adherence behavior. Women were assessed up to 1 year after therapy. Results: The health education program had no additional impact to individual contact during PFME therapy on treatment outcome, nor on adherence. However, the individual physiotherapeutic treatment protocol was very effective in reducing weekly frequency of wet episodes from 23 to 8 times a week immediately after therapy, and effects were maintained during the 1-year follow-up period. Adherence was very high; most women followed the behavioral advice on average 6 days/week at posttest and still 4-5 days 1 year after therapy. Results were not different between incontinence types. Women who had relatively frequent wet episodes before and 1 year after therapy had higher adherence levels compared to women who had fewer weekly losses. Conclusions: Results suggest that a standardized protocol checklist for physiotherapists covering all treatment aspects of PFME therapy, may optimize long-term treatment outcome and adherence behavior among patients, and outshines the addition of a health education program.
