| Objective: To investigate the effect of pelvic floor EMG biofeedback electrical stimulation (PES) on neurogenic bowel (NB) dysfunction induced by spinal cord injury (SCI).Methods：31 patients with SCI complicated with NB were randomly divided into two groups, 15 in the observation group and 16 in the control group. They all received anal and pelvic floor muscle contraction training. The observation group received electrical stimulation biofeedback (25 Hz/75 Hz, 500 μs) training additionally, 20 times, 20 min per time. Before and after treatment, intestinal function score and rectal ultrasonography were evaluated.Results: The Wexner constipation score, Cleveland urinary incontinence score and neurogenic bowel syndrome score were significantly lower in the observation group than in the control group (all P<0.01). As compared with the control group after treatment and the observation group before treatment separately, the thickness of the anal external sphincter and the levator ani muscle in the observation group after treatment was significantly ameliorated (all P<0.01). The change ratio of the thickness of the external anal sphincter and levator ani muscles in the observation group was significantly higher than in the control group (all P<0.01). There was no statistically significant difference before and after treatment in the control group. Conclusion: PES can improve the intestinal function, and increase thickness of external anal sphincter and levator ani muscle in patients with SCI. |
