Test-retest reliability of functional near-infrared spectroscopy during a finger-tapping and postural task in healthy older adults.

ABSTRACT:

Significance

Functional near-infrared spectroscopy (fNIRS) is increasingly employed in studies requiring repeated measurements, yet test-retest reliability is largely unknown.

Aim

To investigate test-retest reliability during a postural and a finger-tapping task with and without cap-removal.

Approach

Twenty healthy older adults performed a postural and a finger-tapping task. The tasks were repeated twice in one session and once the next day. A portable fNIRS system measured cortical hemodynamics (HbO2) in five regions of interest for the postural task and in the hand motor region for finger-tapping.

Results

Test-retest reliability without cap-removal was excellent for the prefrontal cortex (PFC), the premotor cortex (PMC) and the somatosensory cortex (SSC) (int
