Movement evaluation system for measuring movement of the entire body, such as head or hand tremor, has sensor system attached in upper rear area of probands and is placed on spectroscope, and sensor system emits electric signals

摘要

The movement evaluation system has a sensor system attached in the upper rear area of the probands and is placed on a spectroscope. The sensor system emits electric signals of the forward acceleration (a-z), lateral acceleration (a-x), and the lateral angular speed through a band pass filter with a bandwidth of 0.2 to 8 Hertz. The forward and lateral acceleration electrical signals are also emitted by the back-mounted sensor system through a low-pass filter. The electrical signals geometrically directed to the gravitational acceleration to allow the identification of the posture.
