Accelerations, ground reaction force data, and other quantitative data obtained from kinematic analyses of gait initiation serve as measures of dyskinesia in patients with Parkinson's disease. The objective of this study was to determine whether a separate center of pressure information could reveal new characteristics of reduced anticipatory postural adjustments in patients with Parkinson's disease.
Ten healthy elderly subjects and 10 patients with Parkinson's disease participated in this study. Motions at gait initiation in response to a light signal to begin the task were analyzed. Anticipatory postural adjustments were characterized using trunk acceleration data and center of pressure displacement data.
The separated center of pressure in patients with Parkinson's disease showed longer peak latency ( < .01) and larger peak magnitude ( < .01) in the stance leg than in the stepping leg. In patients with Parkinson's disease, the displacement peak latency of the stance leg center of pressure correlated negatively with the Timed Up and Go time ( = -0.46, < .05), while displacement peak latency of the stepping leg center of pressure correlated negatively with Unified Parkinson's Disease Rating Scale (= -0.47, < .05), and positively with Berg Balance Scale score ( = 0.50, < .05).
Patients with Parkinson's disease experience asymmetry between the stance leg and stepping leg at gait initiation. These findings may help clinicians understand the changes to motor function in patients with Parkinson's disease and suggest strategies for improved rehabilitation training.
从步态启动的运动学分析中获得的加速度、地面反作用力数据和其他定量数据可作为帕金森病患者运动障碍的测量指标。本研究的目的是确定单独的压力中心信息是否可以揭示帕金森病患者姿势预适应调整减少的新特征。
本研究纳入 10 名健康老年人和 10 名帕金森病患者。分析了对开始任务的光信号做出反应的起始步态时的运动。使用躯干加速度数据和压力中心位移数据来描述姿势预适应调整。
与迈步腿相比，帕金森病患者分开的压力中心在支撑腿中显示出更长的峰值潜伏期（<0.01）和更大的峰值幅度（<0.01）。在帕金森病患者中，支撑腿压力中心的位移峰值潜伏期与计时起立行走时间呈负相关（= -0.46，<0.05），而迈步腿压力中心的位移峰值潜伏期与统一帕金森病评定量表呈负相关（= -0.47，<0.05），与伯格平衡量表评分呈正相关（= 0.50，<0.05）。
帕金森病患者在步态启动时出现支撑腿和迈步腿之间的不对称。这些发现可能有助于临床医生了解帕金森病患者运动功能的变化，并为改善康复训练提供策略。
