“…5,8 In addition, more and more intervention studies are implementing fNIRS as a primary outcome, comparing cortical activation before and after training in repeated measures designs. [9][10][11][12][13] For example, studies have used fNIRS to investigate learning-induced neural changes in the prefrontal cortex (PFC) as well as in other motor regions during balance 9,12,13 and manual tasks 10,11 in young adults. These studies, however, did not take test-retest reliability into account, crucial for interpreting the changes in the BOLD signal as being meaningful rather than signifying measurement error.…”

.SignificanceFunctional near-infrared spectroscopy (fNIRS) is increasingly employed in studies requiring repeated measurements, yet test-retest reliability is largely unknown.AimTo investigate test-retest reliability during a postural and a finger-tapping task with and without cap-removal.ApproachTwenty 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.ResultsTest-retest reliability without cap-removal was excellent for the prefrontal cortex (PFC), the premotor cortex (PMC) and the somatosensory cortex (SSC) (intraclass correlation coefficient ( ICC ) ≥ 0.78), and fair for the frontal eye fields (FEF) and the supplementary motor area (SMA) (ICC ≥ 0.48). After cap-removal, reliability reduced for PFC and SSC (ICC ≥ 0.50), became poor for SMA (ICC = 0.01) and PMC (ICC = 0.00) and remained good for FEF (ICC = 0.64). Similarly, good reliability (ICC = 0.66) was apparent for the hand motor region without cap-removal, which deteriorated after cap-removal (ICC = 0.38).ConclusionsTest-retest reliability of fNIRS measurements during two separate motor tasks in healthy older adults was fair to excellent when the cap remained in place. However, removing the fNIRS cap between measurements compromised reliability.

Data Processing in Functional Near-Infrared Spectroscopy (fNIRS) Motor Control Research

FNIRS pre-processing and processing methodologies are very important—how a researcher chooses to process their data can change the outcome of an experiment. The purpose of this review is to provide a guide on fNIRS pre-processing and processing techniques pertinent to the field of human motor control research. One hundred and twenty-three articles were selected from the motor control field and were examined on the basis of their fNIRS pre-processing and processing methodologies. Information was gathered about the most frequently used techniques in the field, which included frequency cutoff filters, wavelet filters, smoothing filters, and the general linear model (GLM). We discuss the methodologies of and considerations for these frequently used techniques, as well as those for some alternative techniques. Additionally, general considerations for processing are discussed.

“…Increased OFC activity has been associated with faster response times (Bode et al ., 2018) and hand motor learning (Alves Heinze et al ., 2019). The increased rM1-rOFC functional connectivity observed here may therefore reflect the OFC’s role as a top-down motor control region (Ono et al ., 2014) which is involved in the regulation of motor responses and error monitoring (Alves Heinze et al ., 2019). In line with this hypothesis, Jackson et al (2003) showed increased activation in the right OFC in participants who significantly improved their performance in a right-hand motor task, either having physically executed the task or having performed motor imagery.…”

In humans, motor learning is underpinned by changes in functional connectivity (FC) across the sensorimotor network. Unilateral exercise-induced fatigue increases FC in the ipsilateral primary motor cortex (M1) and supplementary motor area (SMA); areas involved in motor planning and execution of the contralateral hand. Unilateral fatiguing exercise is therefore a promising potential approach to augment motor performance in the non-fatigued, contralateral, hand. In a within-participant, controlled, randomized, cross-over design, 15 right-handed adults had two magnetic resonance imaging (MRI) sessions, where functional MRI and MR Spectroscopic Imaging were acquired before and after repeated right-hand contractions at either 5% or 50% maximum voluntary contraction (MVC). Before and after scanning, response times (RTs) were determined in both hands, and after scanning, participants performed a serial reaction time task (SRTT) with their left, unfatigued, hand. Nine minutes of 50% MVC contractions resulted in fatigue. This unimanual fatigue improved motor performance, as indexed by decreased RTs, in the contralateral hand. Although fatigue had no significant effects on sequence learning, fatigue led to a significant increase in the transfer of the learned skill to the untrained hand. These behavioural effects were supported by significant neural changes: an increase in SMA-SMA functional connectivity, and increased connectivity between right M1 and right Orbitofrontal Cortex. At a neurochemical level, the degree of fatigue-induced decrease in GABA in left M1, left and right SMA correlated with subsequent behavioural improvements in the left-hand. These results support unilateral fatiguing exercise as a potential therapeutic intervention in a range of neurological and orthopedic conditions.
