Learning Potential of Patients With Parkinson's Disease After Two Weeks of Targeted Touchscreen Training

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 form 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 minutes per session. Participants will perform 9 trials of 12 patterns each, alternated with rest periods of 14 seconds. Instruction and answers are also included. Feedback will be provided by means of knowledge of performance. On each training day, participants will receive a reminder on the training tablet.
