About this study

Official title: A Randomized Controlled Trial of a Group-Based Therapeutic Yoga Intervention for Urinary Incontinence in Ambulatory Older Women

The investigators will conduct a randomized controlled trial to evaluate the efficacy of a group-based yoga intervention to decrease the frequency and impact of urinary incontinence in ambulatory middle-aged and older women and explore potential mediators of improvement in outcomes. Women aged 45 years and older who report daily or more frequent stress-, urgency-, or mixed-type incontinence, are not already engaged in formal yoga or muscle stretching/strengthening programs, are willing to temporarily forgo other clinical treatments for incontinence, are able to walk to and use the bathroom without assistance, and meet other eligibility criteria will be recruited from multiple locations surrounding the San Francisco Bay area.

Being tested
Yoga Practice Program, Physical Conditioning Program
Medical subject headings
Urinary Incontinence, Stress, Urinary Incontinence, Urge

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Yoga Practice ProgramOther

    The 3-month yoga intervention will provide instruction and practice in a variety of yoga postures and techniques that have been selected by the study yoga expert consultants for their potential to improve bladder control and safety and feasibility for the target population.

  • Physical Conditioning ProgramOther

    The 3-month muscle stretching/strengthening intervention program (also referred to as the "physical conditioning" program) has been designed by the study physical therapist consultants.

Study groupRoleWhat they receive
Yoga Practice ProgramExperimentalThe 3-month yoga intervention will provide instruction and practice in a variety of yoga postures and techniques that have been selected by the study yoga expert consultants for their potential to improve bladder control and safety and feasibility for the target population. The study will feature a therapeutic program based primarily on Iyengar yoga, a form of Hatha yoga that is known for its potential therapeutic applications.
Receives: Other: Yoga Practice Program
Physical Conditioning ProgramActive comparatorThe 3-month muscle stretching/strengthening intervention program (also referred to as the "physical conditioning" program) has been designed by the study physical therapist consultants. Similar to postures in the yoga intervention program, the exercises in the stretching/strengthening program have been selected for their potential to be performed safely by women across a range of ages and flexibility levels.
Receives: Other: Physical Conditioning Program

Questions about this trial

What is this clinical trial studying?

A study testing Yoga Practice Program and Physical Conditioning Program in people with Stress Incontinence, Female and Stress Incontinence, Urinary, run by University of California, San Francisco at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Oct 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Total Urinary Incontinence Episodes (time frame: Repeated change from baseline to 6 and 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03672461, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2025.
