目的：研究女性不对称负重行走时下肢关节力矩特征，探讨负重侧和无负重侧下肢关节适应机制，为分析女性不对称负重行走可能出现的下肢关节损伤提供依据。
方法：16例健康女性采用单肩背包的不对称负重方式以自身体重的0%、5%、10%、15% 4种负重重量行走，使用Motion红外高速运动捕捉系统和Kistler三维测力台同步采集运动学和动力学数据。
结果：不对称负重会显著减小负重侧下肢膝关节外翻力矩（P<0.05），显著增加无负重侧下肢膝关节外翻力矩和髋关节外展力矩（P<0.05）；无负重侧下肢膝关节外翻力矩和髋关节外展力矩显著高于负重侧下肢（P<0.05），且两侧差异随着负重重量增加而增大。
结论：不对称负重行走，对无负重侧肢体有更大的要求。无负重侧下肢膝关节外翻力矩、髋关节外展力矩均大于负重侧，这种改变可能与关节退变和骨性关节炎的发生相关。 |

| Abstract
Objective： To investigate the effects of asymmetric loads on joint moment characteristics of lower limb in women walking and to explore the adaptation mechanism of lower limb joints for loaded limb stance and unloaded limb stance. This study can provide basis for the analysis of potential lower limb joint injury in women walking with asymmetric loads.
Method： Sixteen healthy women walked carrying a bag on the right shoulder with a loading of 0%，5%，10% and 15% of the subjects' weight. Motion capture system and 2 Kistler force plates were used to collect kinematic and kinetic data synchronously.
Result： Asymmetric loads significantly reduced the internal knee abduction moments in loaded limb stance （P<0.05）， and significantly increased the internal knee abduction moments and the internal hip abduction moments in unloaded limb stance （P<0.05）. The internal knee abduction moments and the internal hip abduction moments were higher in unloaded limb stance as compared to loaded limb stance when carrying asymmetric loads （P<0.05）， and the difference between the two sides increased with the increase of loads.
Conclusion： Walking with asymmetric loads has greater requirements for unloaded limbs. The internal knee abduction moments and the internal hip abduction moments were higher in unloaded limb， which may be associated with the joint degeneration and the development of osteoarthritis. |
