Participants found the drawing tasks relaxing but wanted more time per task.
Sixteen subjects used 12 touch-pens to perform pointing-and-clicking, writing and drawing tasks.
A touch-pen that facilitates natural pointing-and-clicking, writing and drawing tasks each requires a suitable diameter size.
Fifteen PD patients, average disease duration 14.4 ± 7.4 years, were assessed 30 min after a levodopa challenge whilst performing circular and square spiral-drawing tasks.
Additional data included a pre- and post survey of self-perceptions of creativity, prior experience with drawing tasks, and reflections on study participation.
Significant correlations were found between the magnitude of dyskinesia measured from the spiral-drawing tasks and both the 'on' or 'off' UPDRS and also the Bain dyskinesia scale.
In this study, we quantify the severity of drug-induced dyskinesias in the arms of Parkinson's disease (PD) patients using digitised spiral-drawing tasks.
We conclude that the drawing tasks may be used to provide an objective method of quantifying the severity of drug-induced dyskinesias in the arm in PD patients.
Their performance on the typing and drawing tasks wasn't affected by stimulation, however.
At the end, participants were given the Robot-drawing and Control-drawing Tasks, as well as the Motivation, Mechanistic Assessment, and Math in Robot Motion Questionnaires.
The study, titled "Drawing On The Right Side Of The Brain: A Voxel-Based Morphometry Analysis Of Observational Drawing," included 44 graduate and post-grad art students and non-art students who were asked to complete various drawing tasks.
