Objective To evaluate the relationship between spinal cord injury level of SCI patients and ambulatory function wearing advanced reciprocating gait orthosis (ARGO) through three dimensional gait analysis, and to explore the quantizing guideline of reconstructing walking capacity of complete SCI patients. Method Fifteen paraplegic patients with complete spinal cord injury of lesion level between T2 and L1 who had experienced ARGO gait training for at least 3 months were selected into our study. We used 3D gait analysis system of Vicon Nexus to test and analyze these subjects, and examined their gait speeds, cadences, stride lengths, pelvic angles of rotation, hip ranges of motion, crutch forces, angular velocities of hip flexion and extension phases, et al. We use Pearson's product moment correlation coefficient and Spearman rank correlation coefficient to examine the relationship between the level of injury and the kinematic, kinetic and time-spatial values. Results The mean cadence and stride length of these subjects were (34.9±1.97) step/min and (95.7±10.39) cm. Their mean hip range of motion, angular velocities of hip flexion and extension phases were (45.28±4.84)°, (22.34±1.96)°/s and (121.35±10.54)°/s respectively. The gait speed, stride length, peak crutch force, hip ROM, mean crutch force and angular velocity of hip extension phase of SCI patients all had significant pertinences with their spinal cord injury level. Conclusion The abnormal movement of pelvic, limitation of hip range of motion and excess upper limb load are the main reasons that lead to ambulatory disorders in higher thoracic lesion of complete SCI patients. Higher thoracic SCI patients should undertake some rehabilitative training exercises to reduce excessive physiological load, and thus help improve their ambulatory capacity.
