MODERN APPLICATIONS OF FUNCTIONAL NEAR-INFRARED SPECTROSCOPY (fNIRS) IN THE ASSESSMENT OF COGNITIVE RECOVERY AFTER STROKE: A LITERATURE REVIEW
Keywords:
stroke, cognitive impairment, fNIRS, neuroimaging, rehabilitation, NIRSITAbstract
The restoration of cognitive functions following a stroke is one of the key objectives in modern neurorehabilitation. Among the current methods used for objectively assessing the effectiveness of treatment, functional near-infrared spectroscopy (fNIRS) is gaining increasing popularity. This technology allows for non-invasive real-time evaluation of cortical brain activity, especially in areas responsible for higher mental functions. This review discusses the theoretical foundations of the fNIRS method, its technical characteristics, clinical applications, and recent research data confirming its effectiveness in assessing neuroplasticity in post-stroke patients. Special attention is given to the NIRSIT device as one of the most commonly used tools in clinical practice.
