[目的] 帕金森病相关症状可能会影响四肢协调性，并可能导致跌倒风险增加。本研究的目的是比较帕金森病患者与健康老年人在系统控制步行速度时肢体间协调性的变化。 [对象和方法] 参与者在跑步机上行走，同时在 0.22 至 1.30 m/s 之间系统地增加和减少步行速度。运动学数据通过三维运动捕捉系统收集。因变量包括手臂和腿部运动之间以及骨盆和胸部旋转之间的相位关系。 [结果] 与健康对照组相比，帕金森病患者左右臂摆动之间的相对相位变异性增加，手臂、腿部摆动幅度较小，胸椎和骨盆旋转之间的相位关系变异性较小。 [结论] 左右臂摆动相位关系变异性的增加可能与帕金森病患者轴向强直导致肩部手臂运动异相受力减少有关。手臂之间协调性的改善是否可以导致帕金森步态正常化，值得进一步研究。
[Purpose] Interlimb coordination can be affected by the symptoms associated with Parkinson's disease and may result in an increased risk of falls. The purpose of the current study was to compare changes in interlimb coordination in individuals with Parkinson's disease to healthy older adults while systematically manipulating walking speed. [Subjects and Methods] Participants walked on a treadmill while systematically increasing and decreasing the walking speed between 0.22 and 1.30 m/s. Kinematic data were collected by means of a three dimensional motion capture system. Dependent variables included the phase relation between arm and leg movements as well as between pelvic and thoracic rotation. [Results] Compared to healthy controls, an increased variability in relative phase between left and right arm swing, and smaller amplitude with arm, leg as well as less variability for the phase relation between thoracic and pelvic rotations were shown in individuals with Parkinson's disease. [Conclusion] The increased variability of phase relation between left and right arm swing may be related to the reduced out-of-phase forcing of the arm movements at the shoulders as a result of axial rigidity in Parkinson's disease. It deserves further investigation whether the improvement of the coordination between arms could result in the normalization of parkinsonian gait.
