## Abstract By analyzing the kinematics of repetitive, constant‐amplitude, finger oppositions, we compared the impairment of individual and nonindividual finger movements in patients with Parkinson's disease. In one task, subjects tapped only the index finger against the thumb (individual oppositio

✦ Synopsis
Abstract
A retrospective analysis was performed on the records of 33 off‐therapy parkinsonian patients. We analyzed the clinical score of three sequential upper limb movements: finger tapping, hand opening and closing, and forearm pronation and supination. The records showed that nearly all patients had difficulty in performing all three motor tasks, but movement scores showed that they found the sequential finger‐tapping task significantly more difficult than the other two tasks. We suggest that parkinsonian patients find individual finger movements more difficult to execute than gross hand movements because‐owing to their abnormal basal ganglia output‐they lack the finer cortical control and greater facilitation that the finger task demands.
