Fig. 3From: A neuromechanical model characterizing the motor planning and posture control in the voluntary lean in Parkinson’s diseaseThe proposed model for the dynamic reaching test. 'Visual input' is a step function which indicates the target appearance; 'Motor planning' is the trajectory planning section of the task; 'Postural control' is a feedback/feedforward control model for performing the motion commanded as \(\theta _{{ref}}\) from motor planning module, completing the whole task of reach (hitting the target).”Back to article page
