Parkinson’s disease does not alter automatic visual-motor coupling in postural control

摘要: Abstract This study examined the coupling between visual information and body sway in patients with Parkinson’s disease (PD) compared healthy controls. Postural control performance was 14 PD (age: 69.6 ± 8.8 years - stages 1–3 of Hoehn Yahr scale) participants 68.6 ± 3.0 years). Participants stood upright a moving room that remained motionless or continuously oscillated anterior-posterior direction. Ten trials were performed following conditions: no movement (1 trial) at frequencies 0.1, 0.17, 0.5 Hz (3 each frequency). Body displacement recorded. The results indicated displayed larger magnitude stationary condition. induced by manipulation all three stimulus frequencies, but less coherent to participants. However, difference observed visual-body structure. These indicate can unconsciously couple order postural similar manner intact visual-motor for posture control. this is marked greater variability, indicating people have motor system inherent noise leading more varied behavior.
