Finding improvement
Biofeedback restores the ability to relax pelvic floor muscles during straining (94% successful) and evacuate a water-filled balloon (97% successful), and these physiological improvements are strongly associated with adequate pain relief (94.2% of improvers vs 13.6% of non-improvers reported adequate relief, chi-square=93.14, p<0.001).
Effect size94% biofeedback patients achieved pelvic floor relaxation; 97% could defecate balloon; 94.2% of all patients who improved pelvic floor function reported adequate relief vs 13.6% unchanged
ComparatorEGS (also improved relaxation/balloon but less effectively) and massage (did not improve relaxation but partially improved balloon evacuation)
Effect summaryimprovement; 94% biofeedback patients achieved pelvic floor relaxation; 97% could defecate balloon; 94.2% of all patients who improved pelvic floor function reported adequate relief vs 13.6% unchanged
