The Effect of Dopaminergic Medication on Joint Kinematics during Haptic Movements in Individuals with Parkinson’s Disease

Figure 1

Experimental setup. A robotic manipulandum was used to create a virtual space that was passively explored by the participants. (a) Subjects wore goggles and gloves to occlude visual and tactile cues. (b) The participant’s hand was moved along a virtual box (15 cm × 5 cm) that had a left side that was either curved or straight. The maximum curvature experienced by the participant translated to a 2.1 cm deviation from a straight line.
