Attentional Focus and Prefrontal Cortical Activation in Older Adults and Patients With Parkinson's Disease (PD)

Summary

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 older adults and thirty PD will participate in this study.

Detailed description

The subjects will be guided to walk at a normal pace while maintaining the required attentional focus. Subjects will walk on 20 m four 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.

Conditions

• Parkinson Disease

Interventions

Type	Name	Description
OTHER	Functional Near-Infrared Spectroscopy (fNIRS)	The hemodynamic response in prefrontal cortex will be measured using an Octomon+ system (Artinis). Eight emission and two detector probes will be arranged on the participant's forehead.
