Reproducibility of fNIRS Parameters During Walking (REPROXY)

August 1, 2024 updated by: Centre Hospitalier Régional d'Orléans

Reproducibility of fNIRS Parameters During Walking in Stroke Patients and Healthy Subjects

Brain activation can be studied using the Functional Near InfraRed Spectroscopy (fNIRS). It was shown that CPF activation during walking and during dual task could be different in stroke patients and in healthy subjects.

To date, fNIRS reliability is not completely established during walking and during dual task. Therefore, this study will examine the reproducibility of fNIRS parameters during simple walking and during dual task in healthy subjects and in stroke patients.

Conditions

Detailed Description

A fNIRS system will be used to measure the CPF activation. The subjects will walk at their preferred speed on 10 m 3 times and while doing a cognitive task (dual task) 3 times also (in a random order). The same test will be repeated five minutes later. The fNIRS system will be retired and the same test will be repeated 10 min later.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Oxyhemoglobin (HbO) variations during simple walking and during dual task
Time Frame: Day 0
HbO will be measured by the NIR spectrometry technique continuously at rest and during walking. This technique allows to measure the variations of HbO concentration by measuring the variations of light absorption by the explored tissues.
Day 0
Deoxyhemoglobin (HbR) variations during simple walking and during dual task
Time Frame: Day 0
HbR will be measured by the NIR spectrometry technique continuously at rest and during walking. This technique allows to measure the variations of HbR concentration by measuring the variations of light absorption by the explored tissues.
Day 0
