Key result
Functional near-infrared spectroscopy (fNIRS) is reviewed as a noninvasive modality for studying cerebral hemodynamics and its applications in stroke rehabilitation.
Why the study?
Functional near-infrared spectroscopy has gained interest as a noninvasive modality to study cerebral hemodynamic changes related to brain activity across realistic and clinical environments.
This review summarizes the basics, analytical methods, and clinical applications of functional near-infrared spectroscopy (fNIRS) in stroke rehabilitation.
May enable ecologically valid stroke rehab monitoring; leaves open standardized protocols and outcome validation.
Functional near-infrared spectroscopy (fNIRS) has gained great interest as a noninvasive modality to study the changes in cerebral hemodynamics related to brain activity. The unique and beneficial characteristics of fNIRS allow ecologically effective investigations of all ages and conditions in more realistic and clinical environments. In this review, we provide a comprehensive description of fNIRS basics, analytical method developments and applications in stroke rehabilitation. We first review various new methods for the time-series processing and functional analysis of fNIRS data. Then, we review the fNIRS-based application in clinical research for stroke rehabilitation and highlight the exciting developments based on fNIRS. Finally, we discuss the possible technical limitations of the implementation of fNIRS and provide suggestions from different aspects for practical application.
