The Programming and Execution of Movement Sequences in Parkinson'S Disease

摘要: Parkinsonian and neurologically normal subjects performed a finger-tapping task in which different sequence lengths had to be executed as rapidly possible. For each response sequence, reaction time (RT), inter-tap-intervals (ITIs) error patterns were recorded. It was found that the RT-sequence length relationship well group ITI data for two groups, indicative of impaired programming subjects. This conclusion supported by relative dissociation first subsequent taps pattern progressively increasing errors with longer tap sequences Parkinsonians.
