Analysis And Clinical Study Of Pelvic Floor Electromyography Characteristics In Patients With Spinal Cord Injury At Different Nerve Plane Lesion

Objective:To explore the signal characteristics of pelvic floor muscle surface electromyography(s EMG)in patients with spinal cord injury(SCI)at different levels of nerve injury.Subjects and Methods:The experimental group and the control group are compared,and the experimental group is controlled in pairs.Sixty patients with spinal cord injury who met the enrollment criteria were evaluated and studied.After the patient is admitted to the hospital,the basic condition is stable and there is two fecal disorder.After completing the basic routine rehabilitation assessment,the pelvic floor muscle assessment can be performed,that is,the Glazer pelvic floor surface electromyography assessment.The evaluation electrode is placed in female(vagina)and male(anus),and the depth of insertion is five-seven cm.The main evaluation indicators: before and after resting(average uv,coefficient of variation),rapid contraction(fast contraction time s,maximum value,rapid relaxation time s),slow muscle strength assessment(average uv,coefficient of variation),slow muscle endurance test(average uv,coefficient of variation),total time 6 minutes and 38 seconds.Spinal cord injury AISA score,VAS score,Simple bladder volume pressure measurement,comprehensive spasticity assessment scale score,ADL ability of daily living score(Bathel index),measurement of residual urine volume(ultrasound evaluation scan,etc.),all before the patient’s pelvic floor assessment Done.Select the pelvic floor evaluation parameters and use SPSS24.0 for statistical analysis,and set P<0.05 as the difference is statistically significant.Results:volunteers completed the experiment well.1.Compared with the experimental group and the control group(1)The average value of the pre-rest period was statistically different(P<0.001).The pre-rest period variability was not statistically significant compared with the control group(P=0.178).(2)The rapid contraction time in the rapid muscle contraction phase was not statistically different(P=0.262).The maximum value of the rapid contraction period and the rapid relaxation time were significantly different from the control group(P <0.001).(3)The average and variability of the slow muscle contraction stage are statistically significant(P<0.001).(4)The average value and the ratio of the first ten seconds/the last ten seconds of the endurance evaluation stage are statistically significant(P<0.001,P=0.038).there is no statistical difference in the variability compared with the control group Learning significance(P=0.103).(5)The average value of the post-rest assessment stage has a statistically significant difference(P<0.003).The post-rest stage variability compared with the control group has no statistically significant difference(P=0.771).2.Comparison within the experimental groupThe parameters of the cervical,thoracic,and lumbar segments were compared between the three groups before resting,fast contraction,slow muscle contraction,endurance contraction,and post rest,and the differences were not statistically significant((P>0.05).The difference in resting pelvic floor surface electromyography before and after treatment was statistically significant(P<0.05).Although the differences in other parameters were not statistically significant,the overall parameter values developed in a good direction.According to the analysis of urinary log before and after treatment,the difference of urine leakage was statistically significant compared with that before treatment(P<0.05),and the difference in catheterization volume was not statistically significant,but it was improved compared with before,and the bladder volume increased.Conclusions:1.The changes in pelvic floor s EMG values of SCI patients with different injury planes have certain rules,and the consistent performance is in the resting phase,the maximum rapid contraction,the average contraction value of 5 times lasting 10 s and the average value of 60 s continuous endurance contraction The s EMG detection values were all lower than the normal standards,while the slow muscle,endurance variability,and rapid contraction time were higher than the normal standards.2.The pelvic floor surface electromyography assessment Glazer assessment can be used as a quantitative evaluation standard for clinical evaluation of dysfunction in patients with spinal cord injury.It has certain clinical guidance value for the treatment of pelvic floor dysfunction in patients with spinal cord injury and improving the function of feces.
