Fig. 1From: A neuromechanical model characterizing the motor planning and posture control in the voluntary lean in Parkinson’s diseaseA sample of dynamic reaching test (LoS). a The active target is in pink, which is supposed to be hit by the COP (the small red circle) by voluntary lean. When the target is hit, the color changes to blue. The COP trajectory is in green. b The corresponding posture movement towards the target (the subject has to lean toward the target using ankle strategy); c The experimental setupBack to article page
