Abstract
Objectives: To evaluate the correlation between dopa induced gait improvement and upper limb motor improvement using a rapid and simple method; and to evaluate the correlation between gait improvement and UPDRS III improvement.
Methods: A finger tapping test and a simple walking test were used to measure the OFF-ON variations of upper limb motor function and gait in 23 patients with Parkinson's disease. The UPDRS motor score and the Hoehn and Yahr stage were measured in the OFF and the ON state.
Results: There was no correlation between OFF-ON variation of the number of hits with the finger tapping test and OFF-ON variation in the gait variables. OFF-ON variation in the UPDRS motor score was not correlated with OFF-ON variation in the gait variables.
Conclusions: There was a dissociation between the effect of levodopa on upper limb and gait. The findings suggest that simple measures like the finger tapping test and a walking test should be included in the usual evaluation of patients with Parkinson's disease.
