A simple timing movement was used to investigate augmented feedback on motor learning in Parkinson's disease (PD) patients and controls. During acquisition, participants received knowledge of results (KR) about their errors after every trial (100%) or every fifth trial (20%). Participants then performed a retention test without KR. Controls performed better on the retention test after having had 20% KR during acquisition. PDs showed superior retention with 100% KR. This suggests that the PD patients are more reliant on KR for learning motor skills; a difference that may be attributable to reduced proprioceptive acuity in PD patients.
采用一种简单的定时动作来研究帕金森病（PD）患者和对照组在运动学习方面的增强反馈。在习得阶段，参与者在每次试验后（100%）或每五次试验后（20%）获得关于其错误的结果知识（KR）。然后，参与者在没有KR的情况下进行保持测试。对照组在习得阶段接受20%的KR后，在保持测试中表现更好。PD患者在100%的KR下表现出更好的保持能力。这表明PD患者在学习运动技能时更依赖KR；这种差异可能归因于PD患者本体感觉敏锐度的降低。
