The purpose of this study was to investigate the effect of finger movement on ankle control for gait initiation in patients with Parkinson's disease (PD patients). The subjects were 13 PD patients and 6 age-matched healthy adults. The subjects moved fingers before or after gait initiation, or initiated gait without finger movement. Ankle joint movement in the stance leg was recorded to estimate the duration of ankle dorsiflexion (DIF duration), which reflects the degree of disturbance in ankle control for gait initiation in PD patients. In the PD patients with prolonged D/F duration, finger movement that preceded gait initiation shortened the D/F duration, but in the PD patients without prolonged D/F duration and in healthy subjects, the effect was not found. Accordingly, finger movement that precedes gait initiation improves ankle control for gait initiation in PD patients who suffer disturbance in ankle control for gait initiation.
本研究的目的是调查手指运动对帕金森病患者（PD患者）步态起始时踝关节控制的影响。受试者包括13名PD患者和6名年龄匹配的健康成年人。受试者在步态起始之前或之后移动手指，或者不进行手指运动而起始步态。记录站立腿的踝关节运动，以估计踝关节背屈持续时间（DIF持续时间），该持续时间反映了PD患者步态起始时踝关节控制的紊乱程度。在D/F持续时间延长的PD患者中，步态起始前的手指运动缩短了D/F持续时间，但在D/F持续时间未延长的PD患者和健康受试者中，未发现此效果。因此，步态起始前的手指运动可改善在步态起始时踝关节控制受到干扰的PD患者的步态起始时的踝关节控制。
