Abstract
Current
clinical methods for the assessment of Parkinson's disease suffer from
inconvenience, infrequency and subjectivity. WiiPD is an approach for
the objective home based assessment of Parkinson's disease which
utilizes the intuitive and sensor rich Nintendo Wii Remote. Combined
with an electronic patient diary, a suite of mini-games, a metric
analyzer, and a visualization engine, we propose that this system can
complement existing clinical practice by providing objective metrics
gathered frequently over extended periods of time. In this paper we
detail the approach and introduce a series of metrics deemed capable of
quantifying the severity of tremor and bradykinesia in those with
Parkinson's disease. The system has been tested on a 71 year old
participant with Parkinson's disease over a period of 15 days, a 72
year old control user without Parkinson's disease, and a group of 8
young adults. Results indicate a clear correlation between patient self
rating scores of tremor severity and metric values obtained, in
addition to clear differences in metrics obtained from each user group.
These results suggest that this approach is capable of indicating the
presence and severity of the motor symptoms of Parkinson's disease that
affect arm motor control.
