Abstract

Abstract: Objective The walking characteristics of patients with adult spinal deformity(ASD) at pre-operation were analyzed with the three-dimensional gait analysis systemso as to further understand the pathophysiological changes of the lower limb function among patients with ASD, which probably gives physicians guidelines for diagnosis and treatment. Methods Totally 51 ASD patients were included as the observation group, and 51 healthy elderly patients were recruited as the control group according to the general situation (gender, age, body mass index, and basic diseases) of the observation group.Healthy Related Questionnaire of Life (HRQOL) was recorded for all subjects, including Visual Analogue Score (VAS), Oswestry Disability Index (ODI), and Short Form-36 (SF-36).Kinematic parameters were recorded by gait analysis system.At least 10 gait cycles were recorded after marker placed at specific positions of pelvis and lower limbs. Volunteers walked at individual comfortable pace within the set route.SPSS 23.0 software was used to analyze the parameters. Results Compared with the control group, lower limb step length, stride length and stride frequency of ASD patients decreased significantly, and gradually slowed down during walking.The range of flexion and extension of hip and knee joints was significantly reduced in ASD patients.There were statistically significant differences between groups (P<0.05). VAS and ODI were negatively correlated with step length, stride length, step frequency, knee flexion and hip flexion and extension (P<0.05). There was a positive correlation between Physical Component Summary (PCS) in SF-36 and the above indexes (P<0.05). Conclusions Comparing with healthy volunteers, those patients with ASD walked with much slower step frequency, and shorter step length, stride length, knee range of motion, and hip range of motion. There was significant correlation among kinematics data and HRQOL.
