Design and realization of measuring device for tremor evaluation

Tremor as an involuntary rhythmic oscillatory movement of a body part belongs to one of the most disabling features of multiple sclerosis. Our research presented in this paper deals with the developing of an evaluation system of tremor. The system which was designed and realized consists of the portable telemetry units with accelerometers and the base station. The system is able to store 3 axes accelerometry data in the dynamic range of ± 8 g and the sample frequency of 50 Hz. The system allows storing raw data for further processing in PC. The device was verified in the experiment with the gravitational acceleration. The illustration of results from pilot study are presented in the result section. These results show the system ability to trace various types of tremors and distinguish between them.
