PHILADELPHIA – Both a pelvic yoga program and a general physical conditioning program for incontinence led to improvements in women’s incontinence, according to a study presented at the annual meeting of the Menopause Society (formerly The North American Menopause Society).
“As clinicians, we’re usually focused on treatments that we ourselves can prescribe, perform, or administer. We’re not as good as recommending or supporting treatment or management strategies that don’t rely on costly or intensive visits with clinical specialists,” lead author Alison Huang, MD, MAS, a professor of medicine at the University of California, San Francisco, said in an interview.
“But our findings suggest that women who try pelvic yoga as a complementary management strategy for genitourinary conditions like urinary incontinence that often emerge in midlife are likely to experience substantial improvement in their genitourinary symptoms and function,” Dr. Huang said. “Some of these improvements may be shared with other forms of low-impact physical movement or exercise.”
The 240 participants from communities around three Northern California sites ranged in age from 45 to 90 years old, with an average age of 62, and all had at least daily urgency, stress, or mixed-type urinary incontinence. While most were White women, 40% identified as racial/ethnic minorities, including 14% Hispanic, 6% Black, 16% Asian American, and 4% multiracial.
Participants needed to be able to walk two blocks on level ground and get from a supine to a standing position on their own, but they should not have recently participated in any organized yoga or physical conditioning exercise classes. They also needed to forgo behavioral, invasive, or pharmacologic treatments for urinary incontinence for at least 3 months. The trial ran from 2019 to 2022, with most women completing the 3-month program virtually once the pandemic began.
The 121 women randomly assigned to the pelvic yoga program had twice-weekly group instruction by trained yoga instructors and once-weekly individual practice. The practice focused on 16 standard Hatha yoga poses in standing, seated, supine, and prone positions with an emphasis on precise alignment of their postures during each pose. Yoga props, such as blocks, straps, or bolsters, were available to minimize risk of injury and to accommodate women with less flexibility.
The 119 women randomly assigned to the physical conditioning group spent the same amount of group and individual class time on skeletal muscle stretching and strengthening exercises. These exercises focused on strengthening and stretching exercises for the upper and lower extremities in standing, sitting, or supine positions. The only props needed were exercise straps and handles and an exercise mat, and the program was designed to be safe and feasible for women across all ages.
Both groups received standard self-management pamphlets describing pelvic floor muscle exercises and recommendations on timed urination and urging suppression. After early dropouts from both arms, 107 women remained for analysis in the pelvic yoga group, and 113 women remained for analysis in the physical conditioning group.
Researchers assessed participants’ genitourinary quality of life at baseline and after 3 months using the Urogenital Distress Inventory-6 (UDI-6), Incontinence Impact Questionnaire (IIQ), and Patient Perception of Bladder Condition (PPBC). At baseline, the women’s average scores were 38.8 on the UDI-6, 101 on the IIQ, and 3.4 on the PPBC.
About one-third of the women in both groups attended all 24 group classes, and 57% of women in both groups attended 20-23 classes. In addition, 65% of the women in the pelvic yoga group and 73% of the women in the physical conditioning group completed all of the recommended additional hours of individual practice. Only 15% of pelvic yoga participants and 9% of physical conditioning participants completed less than 80% of the recommended individual practice hours. No differences in participation between the groups were statistically significant.
“Over 3 months, scores on all genitourinary quality of life measures improved by more than the minimum important difference thresholds in the pelvic yoga group,” the researchers reported, but only the UDI-6 score improved significantly – albeit still modestly – in the pelvic yoga group, compared with the physical conditioning group. Average scores improved 18.9 points in the pelvic yoga group and 13.1 points in the physical conditioning group (5.8-point difference; P = .02).
The scores on the IIQ improved an average 38.5 points in the pelvic yoga group and 31.4 points in the physical conditioning group (P = .48). PPBC scores improved 0.7 points in both groups.
“While yoga may offer benefits for genitourinary quality of life, it may not offer superior benefits compared to equivalent-time practice of other activities that improve general physical function,” Dr. Huang told attendees.
“The bottom line is that physical activity toward incontinence is a helpful technique,” Stephanie Faubion, MD, MBA, director for Mayo Clinic’s Center for Women’s Health and medical director for the Menopause Society, said in an interview regarding the findings. Urinary incontinence is under-recognized, Dr. Faubion said, “because women are embarrassed, so they don’t bring it up, so it doesn’t get managed.” But it’s a common problem, so clinicians need to ask patients about it, she said.
“We should realize that, in midlife and older age, genitourinary health is often connected to overall health,” Dr. Huang said in an interview. “We shouldn’t focus exclusively on treatments that are directed solely at the genital or lower urinary tract organs or tissues. We should consider the ways in which women’s urinary and sexual function are influenced by other aspects of their physical and cognitive health.”
The research was funded by the National Institutes of Health. Dr. Huang and Dr. Faubion had no disclosures.
