To Study The Three-dimensional Gait Analysis Of Patients With Gluteal Muscle Contracture Treated By Arthroscopy

Objective In our study,to accurately evaluate the gait characteristics of gluteal muscle contracture(GMC)patients and curative effect of arthroscopic minimally invasive treatment and offer scientific references for clinical treatment and rehabilitation,the three-dimensional gait data collection and data analysis of walking gait between patients with GMC(before operation and after operation)and normal persons were carried out.Methods Thirty-nine patients with GMC in the Center of Joint and Sports Medicine of Hunan People's Hospital from 2018 October to 2019 October were selected as the experimental group,including 22 males and 17 females.And 20 healthy people whose age,height and weight matched with the experimental group were selected as the control group.The Vicon-V5 three-dimensional gait analysis system was used for static and constant walking speed test between the experimental group(before operation and after operation)and the control group.Polygon 4.3.0 software,Nexus2.6 software and Origin2018 C software was applied to assess the time and space parameters and SPSS21.0 software was used for statistical analysis.Results1.Patients with gluteal muscle contracture before surgery had smaller stride,step length,and average stride frequency before surgery than the normal control group,and the differences were statistically significant(p <0.05);The stride length and step length were larger than those before surgery,and the difference was statistically significant(p<0.05).Compared with the normal control group,postoperative gait stride length,step length,and average step frequency were the same as normal The control group had no statistical significance(p> 0.05);2.Compared with the normal control group,patients with gluteal muscle contracture before surgery had smaller maximum and minimum hip flexion and extension angles during normal walking than the normal control group,and the difference was statistically significant(p <0.05);The minimum hip anterior andexternal rotation angle was smaller than that of the normal control group,and the difference was statistically significant(p <0.05).The maximum hip adduction and abduction angle before surgery,and the range of adduction and abduction angles were greater than normal.The control group was small and the difference was statistically significant(p <0.05);3.The maximum and minimum angles of flexion and extension of the hip joint during walking compared with those before operation compared with those before operation were greater in the gluteal muscle contracture group than before,and the difference was statistically significant(p <0.05);The minimum value of hip internal and external rotation angle and the range of internal and external rotation angle were smaller than those before surgery,and the difference was statistically significant(p <0.05).The maximum value of hip adduction and abduction angle and adduction and abduction angle after surgery were changed.The range is larger than before surgery,and the difference is statistically significant(p <0.05);4.Compared with the normal control group,the minimum value of the flexion and extension angle of the hip joint during walking was larger than that of the normal control group.The difference was statistically significant(p <0.05).The minimum value was larger than the control group,and the difference was statistically significant(p<0.05).The maximum value of hip adduction and abduction angle and the range of adduction and abduction angle were larger than those of the control group,and the difference was statistically significant(p <0.05);Conclusion1.The gait of patients with gluteal muscle contracture is significantly improved after arthroscopic surgery with good curative effect.2.The three-dimensional gait analysis system can be used as a means to evaluate the effect of surgery for patients with gluteal muscle contracture which complements the traditional efficacy evaluation method.
