帕金森病（PD）使平衡控制能力下降。触觉（触觉和本体感觉）反馈与固定表面的光接触不足以机械稳定平衡改善平衡控制健康人。在这项研究中，我们测试了PD是否会损害独立于机械支持的触觉线索的使用来控制平衡。我们测量了13名PD患者（H&Y 1-3，中位数= 2,Q1= 2,Q3= 2）和13名年龄匹配的对照者在四种情况下以扩大、尖锐的Romberg站立平衡：闭上眼睛、无手接触；闭眼轻触接触（<1 N），闭眼无限制接触；眼睛睁着，不要接触。为了确定PD的严重程度是否会影响这些平衡策略，PD参与者在服药和停药时进行了测试，并在站立和手动接触时使用受影响较大和较小的身体一侧。PD患者无需练习即可同时维持非支持性指尖接触和平衡。PD参与者比对照参与者更容易摇摆（ML CPp= 0.010；肩部p< 0.001），但手接触减少了摇摆。非支持性手触比视力更能稳定平衡（p< 0.05）。pd严重程度因素无显著影响（p < 0.05）。我们得出结论，PD对平衡的影响并不局限于视觉或触觉反馈。然而，来自手动接触的触觉提示，独立于机械支持，可以改善PD患者的平衡控制。我们讨论PD或相关多巴胺能通路不直接影响触觉反馈平衡控制机制，包括手臂/姿势协调和本体感觉整合。
Parkinson's disease (PD) degrades balance control. Haptic (touch and proprioception) feedback from light contact with a stationary surface inadequate to mechanically stabilize balance improves balance control in healthy people. In this study we tested whether PD impairs use of haptic cues independent of mechanical support to control balance. We measured postural sway in thirteen individuals with PD (H&Y 1–3, median = 2,Q1= 2,Q3= 2) and thirteen age-matched controls balancing in a widened, sharpened Romberg stance in four conditions: eyes-closed, no manual contact; eyes-closed light-touch contact (<1 N), eyes-closed, unrestricted contact; and eyes-open, no contact. To determine whether PD-severity affects any of these balance strategies, PD participants were tested on- and off-medication, and using the more- and less-affected body side in the stance and manual contact.Individuals with PD simultaneously maintained non-supportive fingertip contact and balance in this task without practice. PD participants swayed more than control participants (ML CPp= 0.010; shoulderp< 0.001), but manual contact reduced sway. Non-supportive manual contact stabilized balance more than vision (p< 0.05). PD-severity factors had no significant effect (p> 0.05).We conclude the effect of PD on balance is not specific to vision or haptic feedback. Nevertheless, haptic cues from manual contact, independent of mechanical support, improve balance control in individuals with PD. We discuss the implication that PD or associated dopaminergic pathways do not directly affect haptic feedback balance control mechanisms, including arm/posture coordination and proprioceptive integration.
