Automated classification of peripheral movement disorder

Abstract A low cost spectral analysis system for the measurement and analysis of body tremor is described. The system has been implemented using an accelerometer, amplifier and an 8-bit 6502 based microcomputer system (Apple II) complete with purpose-built data acquisition interface and appropriate software. Data is acquired in 8 by 8 s epochs at a sampling rate of 128 Hz for resting, modified postural and postural arm positions and stored for off-line analysis. The time information is transformed to the frequency domain using the Fast Fourier Transform, and the average power spectrum in bands 1–32 Hz is computed for the 64s recording period. Hardware and software aspects of the system are discussed and clinical and research applications outlined.
