文摘
- •
Patients with Parkinson’s disease (PD) show an accelerated drop in total force in accurate two-finger force production tasks performed without visual feedback.
- •
Sharing of the total force between the two fingers drifts towards a 50:50 pattern without a difference between the PD patients and control subjects.
- •
The accelerated force drop in PD may reflect adaptive changes to the documented loss of action stability.
