我们研究了接受医疗治疗的帕金森病 (PD) 患者在涉及现实动作的双手任务中手内和手间的握力协调情况。 PD 患者的握力增加和运动迟缓的迹象是预期的。由于预期部队控制受损，预计部队协调指数也会降低。与健康对照相比，PD 患者表现出握力增加、运动迟缓和异常负载力产生。 PD 患者的手间负荷力协调指数降低，但手间握力协调指数没有降低。 PD 患者的手内力量协调强度与手部动作也存在差异。握力产生增加，加上负载力产生异常，可能会导致 PD 患者在日常活动中精细运动控制能力下降。在临床中整合实际运动功能的定量分析可以帮助临床医生评估帕金森病患者医疗干预的有效性。
We investigated within- and between-hand grip-load force coordination in medically managed Parkinson’s disease (PD) patients during bimanual tasks involving realistic actions. Increased grip force production and evidence of bradykinesia were expected in PD patients. Force coordination indices were also expected to be reduced in PD, due to impaired anticipatory force control. Increased grip force, bradykinesia, and abnormal load force production were exhibited in PD patients as compared to healthy controls. Indices of between-hand load force coordination, but not between-hand grip force coordination, were reduced in PD patients. Discrepancies in the strength of within-hand force coordination with respect to hand action were also noted in PD patients. Increased grip force production, in conjunction with abnormal load force production, may result in reduced fine motor control in PD patients during daily activities. Integrating quantitative analyses of realistic motor function in clinic may assist clinicians in evaluating the effectiveness of medical intervention in PD patients.
