An interventional study of Functional Near-Infrared Spectroscopy (fNIRS) in Healthy, sponsored by Centre Hospitalier Régional d'Orléans. Completed at 1 site in France. Open to participants aged 18 Years to 30 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-09-01.

Attention may influence the motor performance and frontal activity. This study will examine the effect of different attentional focus : internal, external and divided attention (dual task) on prefrontal cortical activation (fNIRS) and on gait performance. Thirty young healthy voluntary adults will participate in this study.
The subjects will be guided to walk at a normal pace while maintaining the required attentional focus. They will walk on 30 m five times in each of the four different focus conditions :1) no instructions about the attentional focus 2) internal focus on their feet movements, 3) external focus on two lines drawn on the floor, 4) divided attention (walking while performing an arithmetic task). A fNIRS system will be used for the prefrontal cortex activation evaluation and FeetMe soles for gait analyses.
Centre Hospitalier Régional d'Orléans is the lead sponsor of 129 studies on the registry; 31 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
30 young healthy voluntary adults
Device: Functional Near-Infrared Spectroscopy (fNIRS)
The hemodynamic response in prefrontal cortex will be measured using an Octamon+ system (Artinis). Eight emission and two detector probes will be arranged on the participant's forehead.
