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

"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."
