A Study on Diagnosis of Parkinson's Disease by Walking Video.

Parkinson’s disease (PD) is a progressive nervous system disorder that accompanied with resting tremor, bradykinesia, muscle rigidity and impaired posture. The diagnosis for gait disturbance in Parkinson’s disease is subjective mostly depends on the experience and skills of experts due to lack of quantitative criterion. As a consequence, nonspecialist doctors could easily make wrong assessment for gait disturbance. Therefore, in this paper, we propose a diagnostic method for PD by analyzing the state of walking with the aids of image processing technology. An experiment was conducted using walking videos recording to confirm the effectiveness of the proposed method.
