Abstract
Parkinson’s Disease (PD) is a neurodegenerative disease caused by the depletion of dopamine in the brain. Tremor, bradykinesia, rigidity and postural stability are the four major symptoms. Like other symptoms, bradykinesia causing unnatural stillness/slowness in motions affects the daily life of the patients. The levels of these symptoms are clinically assessed by a scoring system based on Unified Parkinson’s Disease Rating Scale (UPDRS). However, UPDRS relies on the visual observations of physicians rather than a test based on quantitative measurements. This makes it not only difficulty to repeat but also subjective. Because of these two major disadvantages, researchers build custom devices for their studies. But this leads to the reliability issues and non-standard measurements. Thus, 24 PD patients were bilaterally UPDRS III (motor subsection) scored and recorded for finger motion (pinching) by using commercially available off-the-shelf (COTS) product called Leap Motion.
