Structured Abstract
Background:
Due to the limitations of existing clinical treatments for urinary incontinence, many women with incontinence are interested in complementary strategies for managing their symptoms. Yoga has been recommended as a behavioral self-management strategy for incontinence, but evidence of its feasibility, tolerability, and efficacy is lacking.
Objectives:
To evaluate the feasibility and tolerability of a group-based therapeutic yoga program for ambulatory middle-aged and older women with incontinence and examine preliminary changes in incontinence frequency as the primary efficacy outcome after 3 months.
Study Design:
Ambulatory women aged 50 years or older who reported at least daily stress-, urgency-, or mixed-type incontinence, were not already engaged in yoga, and were temporarily willing to forgo clinical incontinence treatments were recruited into a randomized trial in the San Francisco Bay area. Women were randomly assigned to take part in a program of twice weekly group classes and once weekly home practice focused on Iyengar-based yoga techniques selected by an expert yoga panel (yoga group) or a non-specific muscle stretching and strengthening program designed to provide a rigorous time-and-attention control (control group) for 3 months. All participants also received written, evidence-based information about behavioral incontinence self-management techniques (pelvic floor exercises, bladder training) consistent with usual first-line care. Incontinence frequency and type were assessed by validated voiding diaries. Analysis of covariance models examined within- and between-group changes in incontinence frequency as the primary efficacy outcome over 3 months.
Results:
Of the 56 women randomized (28 to yoga, 28 to control), mean age was 65.4 (±8.1) years (range 55–83 years), mean baseline incontinence frequency was 3.5 (±2.0) episodes/day, and 37 (66%) had urgency-predominant incontinence. Fifty women completed their assigned 3-month intervention program (89%), including 27 in the yoga and 23 in the control group (P=0.19). Of those, 24 (89%) in the yoga and 20 (87%) in the control group attended at least 80% of group classes. Over 3 months, total incontinence frequency decreased by an average of 76% from baseline in the yoga and 56% in the control group (P=0.07 for between-group difference). Stress incontinence frequency also decreased by an average of 61% in the yoga group and 35% in controls (P=0.045 for between-group difference), but changes in urgency incontinence frequency did not differ significantly between groups. Forty-eight non-serious adverse events were reported, including 23 in the yoga and 25 in the control group, but none were directly attributable to yoga or control program practice.
Conclusions:
Findings demonstrate the feasibility of recruiting and retaining incontinent women across the aging spectrum into a therapeutic yoga program and provide preliminary evidence of reduction in total and stress-type incontinence frequency after 3 months of yoga practic...
