Objective To analyze the gait parameters of adolescent idiopathic scoliosis (AIS) patients,and to explore the changes of weight bearing balance and gait kinematics in dynamic walking in patients with AIS.Methods A total of 30 patients with thoracolumbar AIS aged 10~18 who visited the Spine Ward of the Second Hospital of Shanxi Medical University for the first time from May 2021 to September 2021 were enrolled.The patients were divided into three groups according to the direction of scoliosis.There were 9 cases in the left curve group,inlcuding 4 males and 5 females.The age was 11~15 years old,with an average ago of (13.33±2.45) years.Right curve group had 10 cases,including 3 males and 7 females.The age was 12~14 years old,with an average ago of (13.30±2.00) years.There were 11 cases of thoracolumbar scoliosis of the “S” spine,3 males and 8 females.The age was 11~15 years old,and the average age was (13.18±1.47) years.In addition,10 healthy adolescents aged 10~18 years were recruited as the control group,including 4 males and 6 females.The age was 8~13 years old,with an average age of (11.50±1.27) years.The 3D gait analyzer was used to collect the spatiotemporal parameters,joint kinematic parameters and other indicators in the static standing and walking states of the four groups of subjects for detection and comparison,so as to analyze the weight-bearing and gait characteristics of AIS patients in different bending directions.Results (1) Weight bearing status:There were significant differences in weight balance between static standing and dynamic walking between the four groups of AIS patients (P<0.05) and.(2) Gait parameters.①Spatial-temporal parameters:The difference in step length between the four groups was statistically significant (P<0.05).②Kinematic parameters:There were significant differences in the range of motion of hip,knee and ankle joints on both sides of the right curve group (P<0.05).Conclusion Scoliosis alters posture control and gait patterns throughout the body.There are significant differences in static standing weight-bearing and balance,gait analysis temporal and spatiotemporal and kinematic parameters of AIS patients with different lateral bending directions.Further research is needed in the future to seek more gait parameter patterns in AIS patients.
