Clinical effects of biofeedback therapy on functional constipation caused by pelvic floor dys-synergia

Objective To explore the clinical effects of biofeedback (BF) therapy on functional constipation (FC) caused by pelvic floor dys-synergia (PFD). Methods Forty patients with FC caused by PFD were enrolled and given BF therapy twice a week for 5 weeks. Constipation symptom scores and anal motility were recorded before and after the therapy. Results All the patients enrolled finished the BF therapy, with a total effectiveness rate of 80%. Both the constipation symptom scores and anal residual pressure during defecation had decreased significantly after therapy. Rectal gradient pressure, however, had increased significantly. Conclusion Biofeedback can relieve the clinical symptoms of FC and improve pelvic floor coordination during defecation. It is worth applying in clinical practice.
