The Effects of Kegel Exercise Combined With Biofeedback Therapy on Bowel Function Recovery, Emotional Distress, and Quality of Life in Patients Following Low Anterior Resection for Rectal Cancer
Sponsor: National Taiwan University Hospital
Summary
This randomized controlled trial aims to evaluate the effects of combining Kegel exercise with a single biofeedback session on bowel function, emotional distress, and quality of life in patients who have undergone low anterior resection (LAR) for rectal cancer. Low anterior resection syndrome (LARS) is a common postoperative complication following LAR, characterized by increased stool frequency, urgency, and incontinence, which can significantly impair patients' psychological well-being and daily quality of life. Participants will be randomly assigned to one of two groups: (1) Kegel exercise combined with one non-invasive biofeedback session, or (2) Kegel exercise alone. Both groups will perform home-based Kegel exercises for eight weeks. The study aims to determine whether the combined biofeedback and Kegel exercise intervention results in greater improvements in bowel control, emotional well-being, and quality of life compared with Kegel exercise alone.

Interventions
Kegel Exercise with Biofeedback
A single 30-minute non-invasive EMG biofeedback session will guide participants to correctly contract and relax pelvic floor muscles using real-time visual and auditory feedback. Conducted by trained healthcare staff in the physical therapy center, with additional outpatient or ward instruction if needed. After the session, participants perform home-based Kegel exercises for 8 weeks (3-5 times/day, 6-8 contractions/set, hold 5-10 sec, relax 10 sec, ≥5 days/week). Research staff will follow up every 1-2 weeks by phone to monitor adherence and adjust intensity. If stable 5-sec contractions are achieved, duration or frequency may increase; if fatigue, abdominal pressure, or discomfort occurs, training will be reduced or paused for safety.
Kegel Exercise Only
Participants in the control group will receive a single 30-minute session of verbal instruction and demonstration on Kegel exercise by trained medical personnel, without the use of any biofeedback device. The provider, setting, duration, exercise dosage, and follow-up schedule are identical to those in the experimental group.
