Since tremors and muscle stiffness are two of the symptoms of Parkinson's disease, it is more difficult for patients with Parkinson's disease to draw spiral and wavy patterns. This tester, made up of a microcomputer, a scanner, and a display, assesses whether the elders are suffering from the symptoms of Parkinson's disease by the data calculated from the speed and pressure from drawing spiral and wavy patterns. The elders can undergo a preliminary test at an affordable price at home.
