【 摘 要 】

Purpose: We analysed the cognitive influence on walking in multiple sclerosis (MS)patients, in the absence of clinical disability. Method: A case-control study wasconducted with 12 MS patients with no disability and 12 matched healthy controls.Subjects were referred for completion a timed walk test of 10 m and a 3D-kinematicanalysis. Participants were instructed to walk at a comfortable speed in a dual-task(arithmetic task) condition, and motor planning was measured by mental chronometry.Results: Scores of walking speed and cadence showed no statistically significantdifferences between the groups in the three conditions. The dual-task conditionshowed an increase in the double support duration in both groups. Motor imageryanalysis showed statistically significant differences between real and imaginedwalking in patients. Conclusion: MS patients with no disability did not show anyinfluence of divided attention on walking execution. However, motor planning wasoverestimated as compared with real walking.
