Pelvic floor physical therapy for functional constipation in children: a systematic review and meta-analysis.

Constipation in children is common and can be hard to treat, especially when the pelvic floor muscles are not relaxing properly during a bowel movement. This review pooled thirteen randomized trials involving nearly a thousand children to ask whether pelvic floor physical therapy helps beyond conventional treatment alone. The picture that emerged was mixed depending on the specific technique.

Biofeedback, a method that helps children see and learn to control their pelvic floor muscle activity, showed no statistically significant difference from control treatment. However, other approaches, including therapeutic exercise, manual therapy, electrical stimulation, and multimodal programs combining several methods, were associated with more frequent bowel movements, less painful defecation, better quality of life, and less fecal incontinence compared to conventional care. No adverse events related to these therapies were reported.

The main limitation is that trial quality ranged from fair to good, and the interventions grouped as effective were quite varied, making it hard to say which specific technique matters most.

If your child struggles with chronic constipation, you may have heard about pelvic floor physical therapy as a possible extra step alongside standard treatments like diet changes or laxatives. This review looked at the existing research, thirteen studies involving almost a thousand children, to see whether these physical therapy techniques actually help. The results were not uniform across all types of therapy.

Biofeedback, where children learn to control their pelvic floor muscles using visual or sensor feedback, did not show a statistically significant benefit over standard care in this pooled analysis. On the other hand, therapies involving therapeutic exercises, hands-on manual therapy, electrical stimulation, or a mix of approaches were linked to more frequent bowel movements, less painful defecation, improved quality of life, and less accidental stool leakage compared to conventional treatment alone.

No harmful effects tied to these therapies were reported. It is important to understand this comes from combining several different studies of varying quality, and the therapies lumped together were diverse, so it is not yet clear which specific technique drives the benefit.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

This systematic review and meta-analysis pooled thirteen randomized controlled trials (997 children) comparing pelvic floor physical therapy approaches to conventional treatment for pediatric functional constipation. Methodological quality, assessed via the PEDro scale, ranged from four to eight, indicating fair to good quality across the included trials rather than uniformly high-quality evidence. Biofeedback specifically showed no statistically significant difference from control (risk ratio 0.91, 95% CI 0.50 to 1.68).

In contrast, when therapeutic exercise, manual therapy, electrical stimulation, and multimodal treatment were considered, pooled results favored these approaches over conventional treatment: increased defecation frequency (mean difference 1.89, 95% CI 1.30 to 2.47), reduced painful defecation (risk ratio 0.69, 95% CI 0.54 to 0.89), improved quality of life (standardized mean difference 1.14, 95% CI 0.26 to 2.01), and reduced fecal incontinence (risk ratio 0.59, 95% CI 0.46 to 0.74). No adverse events attributable to pelvic floor physical therapy were reported across studies. Clinicians should note that these positive outcomes were derived from grouping heterogeneous intervention types together, which limits conclusions about which specific modality is responsible for the effect, and the abstract does not report head-to-head comparisons between these active treatments.
