Figure 1

Angular velocity traces measured during repetitive wrist flexion-extension OFF deep brain stimulation (DBS; A); the insert on the right at higher magnitude demonstrates the severe progressive bradykinesia, ON open-loop STN DBS (olDBS; B) and after 60 min of closed-loop STN DBS (clDBS) (C). Schematic of the DBS lead demonstrates the use of a triple monopole during olDBS and a single monopole during clDBS. Vrms: the root mean square angular velocity averaged over the trial.
