Treatment of the spastic pelvic floor syndrome with biofeedback.

The spastic pelvic floor syndrome is a functional disorder based on contraction instead of relaxation of the pelvic floor muscle during straining, which inhibits defecation and gives rise to constipation. Until now no adequate treatment has been found for this condition. The treatment described here is aimed at teaching patients to relax their pelvic floor muscle during straining. Treatment consists of a training program with EMG feedback, followed by simulation of the defecation process, using oatmeal porridge. Patients are then given instructions to generalize the relaxation response in their daily lives. Treatment was completely successful in seven of ten patients. The three remaining patients learned to strain in the correct manner, but could not achieve generalization. Two of them underwent subtotal colectomy because of delayed colonic transit times, which subsequently resulted in normal evacuation. In the third patient, the generalization was most likely hampered by psychologic problems, for which she now receives psychotherapy.
