To compare the kinematics of lower limb joints between individuals with and without chronic ankle instability (CAI) during cross-turn and -cutting movements.
Cross-sectional study.
Motion analysis laboratory.
Twelve subjects with CAI and twelve healthy controls.
Hip flexion, adduction, and internal rotation, knee flexion, and ankle dorsiflexion and inversion angles were calculated in the 200 ms before initial ground contact and from initial ground contact to toe-off (stance phase) in a cross-turn movement during gait and a cross-cutting movement from a forward jump, and compared across the two groups.
In the cross-cutting movement, the CAI group exhibited greater hip and knee flexion than the control group during the stance phase, and more hip abduction during the period before initial contact and the stance phase. In the cross-turn movement the joint kinematics were similar in the two groups.
CAI subjects exhibited an altered pattern of the proximal joint kinematics during a cross-cutting movement. It is important for clinicians to assess the function of the hip and knee as well as the ankle, and to incorporate coordination training for the entire lower limb into rehabilitation after lateral ankle sprains.
比较慢性踝关节不稳（CAI）患者与非慢性踝关节不稳患者在交叉转身和切入动作中下肢关节的运动学特征。
横断面研究。
运动分析实验室。
12名CAI患者和12名健康对照者。
在步态中的交叉转身动作以及向前跳跃的切入动作中，计算初始地面接触前200毫秒以及从初始地面接触到离地（支撑期）期间的髋关节屈曲、内收和内旋、膝关节屈曲以及踝关节背屈和内翻角度，并在两组之间进行比较。
在切入动作中，CAI组在支撑期表现出比对照组更大的髋关节和膝关节屈曲，在初始接触前和支撑期表现出更多的髋关节外展。在交叉转身动作中，两组的关节运动学特征相似。
CAI患者在切入动作中表现出近端关节运动学特征的改变。临床医生评估髋关节、膝关节以及踝关节的功能，并将整个下肢的协调训练纳入踝关节外侧扭伤后的康复治疗中非常重要。
