Abstract:
Objective To evaluate the effect of biofeedback therapy for the treatment of myogenic fecal incontinence. MethodsA general assessment about anorectal function was made on 17 cases receiving biofeedback therapy including muscle power training,sensory training and coordination training. Results The clinical scores before and after biofeedback therapy were 1.66?0.23,3.80?0.42 respectively,with an effective rate of 82%. The anus maximum contracting pressure elevated,(73?20) mm Hg vs. (123?30) mm Hg; myoelectric amplitude increased,(122?32) ?V vs. (230?41) ?V;Contracting time prolonged,(4.1?2.0) s vs. (9.4?3.0) s; The sensory threshold was lowered,(50?12) ml vs. ( 20? 10) ml;The feel-contract time increased,(3.1?0.4) s vs. (1.2?0.3) s. Positive rectal contraction reflex was seen in 41% patients before therapy compared with 82% after therapy. Conclusions Biofeedback therapy increases contractility of sphincter,decreases threshold of rectal sensory,and is a therapy of choice for myogenic fecal incontinence.
