Voluntary vs autonomous control of repetitive finger tapping in a patient with Parkinson's disease.
Fourier analysis was used to investigate the role of perceptual information in controlling repetitive finger tapping in a patient with unilateral Parkinsonian tremor. The results are interpreted in the context of Von Holst's theory of relative co-ordination, and demonstrate the subject's reliance on extrinsic information to counteract tremor when performing voluntary repetitive movement.
