Abstract:

Objective 　To adopt electromyography for measuring abdominal muscles and diaphragmatic surface electromyographic change, and to use CSS for evaluation of the effect of respiratory electrical stimulation training in patients with functional constipation.　Methods　The study enrolled 31 patients with functional constipation，who were randomly divided into control group and treatment group. The control group was treated with biofeedback therapy (16 cases), and the treatment group was treated with respiratory electrical stimulation and pelvic floor biofeedback (15 cases).Surface electromyography technique was used to measure the surface electromyogram of the diaphragm and the lower abdomen，respectively, before treatment and after treatment in two groups with CSS，Glazer method was used to evaluate the parameters of pelvic floor muscle.　Results    After 2 weeks of treatment， severity score of patients with chronic constipation in the two groups lower than that before treatment（P<0.05）.And the score of the treatment group was lower than that of the control group（P<0.05）. root mean square value of the diaphragm and rectus muscle in patients of the two groups is better than that before treatment（P<0.05）. But there was significant difference between the treatment group and the control group（P<0.05）.After treatment，the Glazer method was used to evaluate the baseline amplitude values in two groups of patients, which demonstrated a lower value after treatment（P＜0.05）. The Anterior baseline amplitude of the treatment group was lower than that of the control group, and the difference was statistically significant（P＜0.05）.　Conclusion　The respiratory electrical stimulation training can effectively improve the contractility of diaphragm and abdominal muscles and reduce the excessive activity of pelvic floor muscles, and enhance pelvic floor biofeedback in the treatment of functional constipation.
