Key Takeaway
Consider 8-week home biofeedback as potentially equivalent to 16-week for FI in women, but evidence is preliminary.

This single-blind, equivalence randomized clinical trial enrolled 38 women with fecal incontinence (FI), with 36 (18 per arm) providing complete data. Participants had a mean age of 62.4 years, and 97.3% were non-Hispanic White. The study compared an 8-week duration versus a 16-week duration of the same home-based digital therapeutic pelvic health system, which included biofeedback and optional remote health coaching with twice-daily exercises. The primary outcome was change in FI severity measured by the Vaizey score from baseline to 16 weeks.

Both treatment durations led to significant improvement in FI severity over time. The 8-week group had a mean score change of -4.7 (±5.1), and the 16-week group had a change of -4.8 (±4.5). The between-group difference was not statistically significant (P = 0.918), indicating equivalence. The improvements in both groups met the threshold for the minimal clinically important difference for the Vaizey score.

Safety and tolerability data were not reported. The study has several key limitations, including a small sample size (targeted 15 per arm, achieved 18 per arm), limited demographic diversity (predominantly non-Hispanic White women), and a follow-up period limited to 16 weeks. Funding sources and conflicts of interest were not reported.

For practice, this preliminary evidence suggests that an 8-week home-based biofeedback program may be as effective as a 16-week program for improving FI symptoms in the short term among a specific patient population. However, clinicians should interpret these results cautiously due to the small study size and lack of generalizability. The findings highlight a potential avenue for more efficient treatment delivery but require validation in larger, more diverse trials with longer follow-up.

Fecal incontinence can be isolating and deeply frustrating, making everyday life feel unpredictable. A new study looked at whether a shorter home therapy program could offer the same relief as a longer one. The therapy involved a digital system with biofeedback exercises done twice daily at home, with optional remote coaching from a health professional.

Researchers worked with 36 women who had fecal incontinence. They compared an 8-week program to a 16-week program. Both groups saw their symptoms improve significantly over the 16-week study period, and the amount of improvement was essentially the same for both the shorter and longer programs. The improvement was enough to be considered meaningful in daily life.

It's important to view these results as a promising first step, not a final answer. The study was quite small, and nearly all participants were white, so we don't know if the results would be the same for a larger, more diverse group of people. The researchers also only followed participants for 16 weeks, so we don't know if the benefits last longer than that. Still, for women looking for options, this points to a potential at-home approach that might require less time than previously thought.

What this means for you:
In a small study, 8 weeks of home therapy for fecal incontinence worked as well as 16 weeks.

IMPORTANCE: Access to biofeedback, a first-line treatment for fecal incontinence (FI), is limited. OBJECTIVE: The objective of this study was to evaluate whether an 8-week duration of a home-based digital therapeutic pelvic health system to treat FI in women is equivalent to a 16-week duration. STUDY DESIGN: We conducted a single-blind, randomized, equivalence trial in women with FI. Participants were randomized to 8 or 16 weeks of twice-daily exercises using the system and could opt to participate in remote health coaching. The primary outcome was the change in FI severity as measured by the Vaizey score from baseline to 16 weeks. Our target sample size was 15 participants per arm. Paired t test, χ2 test, and McNemar-Bowker test compared differences over time and between groups. RESULTS: Among 38 women enrolled, 36 (18 per arm) provided complete data. All received allocated treatment, with a mean adherence of 75.2%. Most participants identified as non-Hispanic White (97.3%), with a mean age of 62.4 ± 15.4 years and a mean body mass index 29.5 ± 8.9. Baseline FI severity was high and improved significantly over time in both groups. Treatment duration of 8 weeks was equivalent to 16 weeks with changes in Vaizey scores that reached the minimal clinically important difference in both groups (-4.7 ± 5.1 vs -4.8 ± 4.5, P = 0.918). CONCLUSIONS: FI outcomes improved significantly with a home-based pelvic health system with biofeedback and remote health coaching used for either 8 or 16 weeks, without significant differences between groups.
