Abstract:Objective To observe the effect of biofeedback stimulation of pelvic floor muscles on micturition dysfunction in patients with spinal cord injury(SCI). Methods From October 2016 to October 2018,64 patients with SCI and micturition dysfunction were randomly divided into the control group (n=32) and the treatment group (n=32).Both groups received pelvic floor muscle function exercises,and the treatment group added biofeedback stimulation therapy for a total of 8 weeks.The Glazer pelvic floor surface electromyography (sEMG) curve test［select the maximum value of 5 fast shrinks (Flick-Max),the average value of the 60-s contraction (Edu-Mean)］,bladder residual urine volume test,and International Spinal Cord Injury Data Sets-Lower Urinary Tract Function Basic Data Set were performed before and after treatment in patients of the two groups to evaluate the efficacy. Results After treatment,Flick-Max in two groups and Edu-Mean in treatment group were significantly higher than those before treatment (all P<0.05);Flick-Max and Edu-Mean in the treatment group were higher than those in the control group (all P<0.01).After treatment,the bladder residual urine volume was significantly reduced in both groups than before treatment (all P<0.01),and which in the treatment group was less than that in the control group (P<0.01).The results of the questionnaire survey indicated that after treatment,the urination,urinary symptoms,and bladder emptying in the treatment group were significantly improved than those before treatment and in the control group (P<0.05,P<0.01),while only the urination in the control group was improved (P<0.01);the urinary incontinence was comparable in both groups (P>0.05). Conclusion The clinical effect of pelvic floor muscle biofeedback stimulation combined with pelvic floor muscle exercise on micturition dysfunction in SCI patients is better than that of pelvic floor muscle exercise alone.
