Effects of Motor Pace on Frontal Haemodynamic Activity during Whole-Body Movements

Even with the recent works on fNIRS robustness and reproducibility, this technique still lacks of standardised methodological precautions and evidence-based recommendations to guide whole-body movement protocol building. We present a procedure that aimed at verifying the stability of the fNIRS headset during whole-body movements, to properly track the anatomical locations of the recorded signals. In addition, we showed that averaging at least 10 trials for a block-design procedure is necessary to improve fNIRS reproducibility and to obtain a robust haemodynamic response. Finally, we demonstrated that the test–retest reliability of fNIRS signals is high, even in whole-body movement motor paradigms.
