摘要：Aim: The aim of this study was to investigate the acquisition and performance of a more complex bilateral obstacle stepping task compared to unilateral obstacle stepping in Parkinson’s disease (PD) patients and healthy age-matched control subjects.Preliminary evidence evidence suggests that impaired force control during walking may contribute to freezing episodes,with difficulty to unload the swing leg and initiate the swing phase,we used external loading to manipulate force control and to investigate its influence on freezing of gait.Methods: We used obstacle stepping and trendmill.Gait tasks were used to provoke freezing episodes,quantified using blinded,videotaped clinical assessment.Reading the literature.Observation.Tests.Trials.Results: The subjects were informed about the experiments and gave written consent.15 patients with PD and 15 age-matched healthy subjects participated.Inclusion criteria for the patients were the diagnosis of idiopathic PD according to the UK Parkinson's disease Brain Bank criteria and Hoehn and Yahr stages 1.5-3.Only subjects who were able to walk unassisted on the treadmill at a speed of 2 km/h were included.We evaluated: -the ability of PD patients to acquire and perform a high-precision bilateral locomotor task.Conclusions:Task performance improved with repetition in both PD and healthy subjects.This suggests a motor learning in both groups but depending on the task investigated,it was suggested that a dysfunction of the basal ganglia resulted in a difficulty to switch between motor programs.
