Clinical symptoms of idiopathic Parkinson’s Disease
• Four major motor dysfunctions: bradykinesia
rigidity tremor at rest
postural instability
bradykinesia

Progressive neurodegeneration
Anatomically Parkinson’s Disease exhibits a progressive degeneration of the substantia nigra cells that are interconnected with dopaminergic neurons in the striatum part of the basal ganglia.

Research questions
• 1.) How PDs and healthy adults differ in temporal control of the movement under different spatial, temporal and informational constraints?
• 2.) Can paradoxical kinesia be explained by coupling the movement to the sensory information available?
