Improvement of neurogenic bowel dysfunction after spinal cord injury using functional magnetic stimulation based on anorectal manometry / 国际生物医学工程杂志

ABSTRACT

Objective:To explore the effect of functional magnetic stimulation(FMS) on the intestinal function of patients with neurogenic bowel dysfunction (NBD) after spinal cord injury using anorectal manometry technology.Methods:36 NBD patients were divided into FMS group and control group by random number table method. Patients in the control group received conventional treatment, including diet adjustment, abdominal massage, and pelvic floor muscle training. Patients in the FMS group received FMS treatment on the basis of conventional treatment. Using 3D high-resolution anorectal manometry and neurogenic intestinal dysfunction score, the intestinal function of the two groups of patients before and after the treatment were evaluated.Results:After receiving conventional treatment + FMS treatment, the high-pressure belt length, anal systolic pressure, rectal pressure, rectal-anal pressure difference, initial sensory threshold, bowel sensation threshold, maximum tolerance threshold, rectal compliance of the patients in the FMS group received were better than those before the treatment (all P<0.05). After receiving conventional treatment, only the rectal-anal pressure difference, initial sensory threshold and maximum tolerance threshold of the patients in the control group were significantly improved (all P<0.05). The improvement of the FMS group on the length of the high-pressure belt, anal systolic pressure, rectal pressure, and initial sensory threshold was significantly better than those of the control group (all P<0.05). Conclusions:The implementation of FMS therapy on the basis of conventional treatment can better improve the intestinal motility and intestinal sensation of the patients with NBD. The 3D high-resolution anorectal manometry technique can be used to quantitatively evaluate the intestinal function of NBD patients.
