摘　　要：目的观察膝骨关节炎(knee osteoarthritis,KOA)患者和健康人群在练习太极云手初学阶段的下肢动态稳定性和运动学、动力学特征差异。方法招募30名太极初学者,包括15名KOA患者和15名健康对照组,在太极拳专家的指导下进行2 h太极云手练习。采用运动捕捉系统和三维测力台,采集并计算云手运动过程中左侧下肢的动态稳定性指标以及运动学和动力学指标。结果与健康对照组相比,KOA患者在云手动作中表现出更小的内外侧倾斜角,踝关节背屈角度的均值和峰值均减少,髋关节内收角度峰值减少,而膝关节屈曲峰值力矩增大(P<0.05)。结论KOA患者采用了适应性的姿势策略以维持太极云手运动中的横向稳定性,但在运动初学阶段应建议采用综合训练方案以减少下肢屈曲时的关节负荷。Objective To observe the differences in dynamic stability and kinematic/kinetic characteristics of the lower limbs between patients with knee osteoarthritis(KOA)and healthy individuals at the begining stage of practicing Tai Chi Yunshou movement.Methods Thirty Tai Chi beginners,including 15 patients with KOA and 15 healthy controls,were recruited to practice Tai Chi Yunshou movement for two hours under the guidance of a Tai Chi expert.A motion capture system and a three-dimensional force platform were used to collect and calculate dynamic stability parameter as well as kinematic and kinetic parameters of the left lower limb during the Yunshou movement.Results Compared with healthy controls,patients with KOA demonstrated a smaller center of mass(COM)-center of pressure(COP)inclination angle,reduced mean and peak ankle dorsiflexion angle,reduced peak hip adduction angle and increased peak knee flexion moment during the Yunshou movement(P<0.05).Conclusions Patients with KOA use adaptive postural strategies to maintain the lateral stability in Tai Chi Yunshou exercise,but a comprehensive training programme should be recommended to reduce the joint loading during flexion of the lower limbs at the benginning stages of this exercise.
