case_images: A. Power spectrum analysis of accelerometer recording from patient 3. Peak frequency and harmonic frequencies are depicted. The unit for amplitude is g2/Hz. The frequency unit is hertz. Half-peak bandwidth shown in the figure was calculated as the width of the spectral peak at one-half the peak amplitude in the power spectrum. High-frequency harmonic frequencies are shown B. Accelerometer tracing reveals that the oscillations were rhythmic but the waveforms were not necessarily sinusoidal. C. EMG bursts recorded from extensor carpi radialis muscle of patient 3. D. EMG recording of extensor carpi radialis muscle revealing 75-85 ms as the average duration of bursts.
