D020521 Clinical Trial
Official title:
Using Functional Near-infrared Spectroscopy (fNIRS) in the Evaluation of Cognitive-motor Interference in Post-stroke Patients
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 is a motor task that involves cognitive functions. The parameters of walking and
brain activity are modified in situations requiring significant attentional and cognitive
demand. fNIRS is an interesting functional neuroimaging technique for studying cortical
activity when performing a Dual Task (DT). To our knowledge, no studies have examined
cerebral oxygenation levels in post-stroke patients based on different cognitive loads during
walking. Understanding cognitive contributions in a dual-task walking situation is necessary
to providing targeted interventions and preventing falls.
Patients included in the study will be evaluated in single cognitive task, with two levels of
difficulty, single walking motor task, and dual task with two levels of cognitive difficulty.
The fNIRS will record the hemodynamic activity of the prefrontal cortex for the cognitive
slope and the GAITRite will record the walking parameters.
