不完全脊髓損傷患者之步態表現

Purpose: This study was to investigate the temporal-distance and kinematic gait performance in individuals with incomplete spinal cord injury. Methods: Seventeen subjects who could walk independently for a minimal of 5 meters participated in this study. A VICON 370 motion analysis system was used to examine the gait performance at the self-selected preferred walking speeds. Subjects walked along a 9-meter walkway for 10 trials. Results: The average cadence was 71±31 steps/mm; the average walking speed was 52.04±41.75 cm/sec; the average stride length was 73.22±38.16 cm; the average stride length normalized to leg length was 0.86±0.45; the average single limb support duration was 25.70±11.57% of gait cycle. The maximal hip extension at terminal stance was limited. The knee joint showed exaggerated flexion at initial contact, insufficient flexion at loading response, hyperextension at mid stance, and limited fiexion at swing phase. The ankle joint showed insufficient plantar flexion at loading response and initial swing, and exaggerated dorsiflexion in swing phase. Conclusion: Abnormal gait pattern was noted in individuals with incomplete spinal cord injury.
