fNIRS in the Evaluation of Cognitive-motor Interference in Post-stroke Patients

NCT03559283 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 11

Summary

This study evaluates cognitive-motor interference in stroke patients who is responsible an alteration of spatio-temporal gait parameters. It's proved in the literature but the underlying pathophysiological mechanisms remain poorly understood. fNIRS is a functional imaging technique that evaluates this interference under optimal conditions. The purpose of this study is to evaluate the hemodynamic activity of the CPF in walking post-stroke patients under different DT conditions.

Walking and Record Cortical Activity

The cortical activity of each patient is recorded by NIRS under the following conditions: * Simple task : The patient walks on an electronic walking track (GAITRite system) over 10 meters. The data collected are the spatio-temporal parameters of walking. * Cognitive task alone : two conditions of the n-back test (1-back and 2-back) to study neural activities related to working memory. The duration of realization will be 30 seconds by condition and we retain the number of errors realized. * Double Task : Achievement of the motor task (10-meter walk) is performed at the same time as a "weak" cognitive task (1-back) and a "high" cognitive task (2-back). The spatio-temporal parameters and the number of errors are collected by the observer.
