[Purpose] The purpose of this study was to investigate the effects of treadmill training on functional recovery by analyzing the ankle joint as well as the knee and hip joints with 2D video analysis during gait by rats with sciatic nerve injury. [Subjects and Methods] Twenty-four male Sprague-Dawley rats were used in this study. The sham group (SG) received only a sham operation without any sciatic injury; the training group (TG) performed treadmill training for 4 weeks after sciatic injury; and the control group (CG) wasn't provided with any therapeutic intervention after sciatic injury. [Results] The ankle, knee, and hip ROM of TG and CG during the initial, mid stance, and toe-off phases of gait at post-test were significantly different from SG. [Conclusion] Physical exercise, like treadmill training, is beneficial for the improvement of the ankle, knee and hip joints of rats with crushed sciatic nerve injury.
[目的] 本研究的目的是通过二维视频分析，在坐骨神经损伤大鼠步态过程中分析踝关节以及膝关节和髋关节，探讨跑步机训练对功能恢复的影响。[对象与方法] 本研究使用了24只雄性Sprague-Dawley大鼠。假手术组（SG）仅接受假手术，无任何坐骨神经损伤；训练组（TG）在坐骨神经损伤后进行4周的跑步机训练；对照组（CG）在坐骨神经损伤后未接受任何治疗干预。[结果] 测试后，TG和CG在步态初始、中期支撑和蹬离阶段的踝关节、膝关节和髋关节活动度与SG有显著差异。[结论] 像跑步机训练这样的体育锻炼有利于改善坐骨神经挤压伤大鼠的踝关节、膝关节和髋关节。
