Abstract：Objective:To investigate reference and support gluteal muscle contracture patients with gait function quantified targets for the disease diagnosis. Methods:16 cases with gluteal muscle contracture admitted to hospital from August 2011 to November 2011 were selected as the study group, in the same period, 16 healthy volunteers were selected as the control group, the application of three-dimensional gait system of the two sets of three-dimensional gait analysis.Results:①Gait cycle time parameters: compared with the control group ,the research group at normal speed, fast walking gait cycle was significantly longer (P＜0.01) , the stride and pace were significantly reduced compared with the control group (P＜0.01).②Lower extremity joint angle characteristics: compared with the control group, hip swinging period of maximum flexion angle when the research group at normal speed, fast walking, when the research group fast walking hip flexion angle range was reduced (P＜0.05);When the research group at normal speed and fast walking, knee coronal plane angle range were increased (P＜0.05), while knee support maximum flexion and knee flexion angle range were decreased(P＜0.01);When the research group at normal speed walking, the center of gravity of left and right shifting increases(P＜0.05). The center of gravity of the fast walking vertical displacement decreased(P＜0.05).Conclusions:Functional quantitative evaluation of the application of three-dimensional gait analysis system gluteal muscle contracture patients can be more accurate understanding of the gluteal muscle contracture patients with gait biomechanical changes, and provide reference and support for the patient's diagnosis, treatment and rehabilitation.
