How do people plan and adjust reaching movements?

Researchers study how people with Parkinson’s choose movement goals and adapt reaching movements when conditions change.

Full study name & original research details

Official study title

Behavioural Study of Reaching Control in Healthy Volunteers and Volunteers With Parkinson Disease in Dynamical Context

Short title used by the registry

Flexible Reaching Control in Parkinson Disease

Original description

Current research and theories have highlighted that the parameters linked to movement planning, e.g. the decision to select a movement goal, and adaptation, e.g. the ability to update control dependent on a novel dynamical context, are update quickly and within an ongoing movement in the general population. In parallel, it has been suggested that the evaluation of movement costs is a function of the basal ganglia, and it is impaired in Parkinson disease (PD). Here the investigators want to test whether these mechanisms also alter the ability of patients to update control during an ongoing action. A positive result would confirm that movement-related costs and dynamical representations depend on the integrity of the basal ganglia, in contrast a negative result would indicate that the deficit in PD is more specifically related to movement initiation, which would invite one to reconsider the cause of bradykinesia in this population.
