Predicting Motor Learning of an Upper Limb Task Based on Behavioral and Disease-specific Characteristics in Patients With Parkinson's Disease

Participants will practice the Swipe-Slide Pattern (SSP) task independently at home in both ST and DT condition, offered in a random order. During this task, participants perform different pre-defined patterns by moving their finger over a touchscreen, resembling a touchscreen unlock trace. The DT condition includes the SSP-task while counting either red or green lights illuminated on the screen. They will receive 10 training sessions of the SSP-task over a period of two weeks. Each week will consist of 5 consecutive days of training for approximately 10 min. per session. Participants will perform 9 trials of 12 patterns each, alternated with rest periods of 14s. Instruction and answers are also included. Feedback will be provided during the rest periods.
