A systematic review of the literature in relation to the theoretical knowledge base for the-Clinical-functional research by evaluation including the modern apparatus modality of functional exploration: near-infrared spectroscopy (Near - Infrared Spectroscopy - N.I.R.S. / Function Near-Infrared Spectroscopy - fN.I.R.S.) of blood oxygenation in the cerebral circulation at repose and during physical activity, respectively, in adolescents with hemiplegia in the context of Cerebral Palsy, compared to patients of the same age group with non-neurological disorders

fNIRS is also called Optical Topography (OT) or simply NIRS. Using - near-infrared spectroscopy - the amount of oxyhemoglobin and deoxyhemoglobin is measured to estimate cortical hemodynamic activity that occurs in response to neuronal activity. Next to EEG, NIRS/fNIRS is one of the newest non-invasive neurophysiologic techniques that can be used in portable settings. The device, OxyMon - with which we have the important opportunity to work is the first and so far the only one in Romania - uses as technology a continuous wave NIRS/fNIRS system with infrared light emitters that emit at least two wavelengths each (700-900nm). Specifically, a fiber end that connects to the OxyMon is called a connector: and a fiber end on the skin is called an optode (transmitter or receiver). Optodes are fixed in an optode holder. The distance between the optodes is called the source-detector distance or interoptode distance. An emitter optode and a receiver optode together form an optode combination or channel. NIRS/fNIRS is a non-invasive brain imaging method and is a suitable technique for detecting brain activity during motor dynamics. After using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (acronym PRISMA) method to quest for afferent knowledge, it resulted a quite small number of 10 related articles, of which only 6 remained eligible for our theme (4 were excluded for objective reasons). fNIRS is a niche field in which there are possibilities of deepening and of personal contribution within the doctoral research topic that we have proposed, being the first and only fNIRS apparatus in Romania, so the clinical-applied apparatus research represents an element that we have not encountered in the Romanian literature. The application of NIRS/fNIRS in neuromotor rehabilitation is still new and immature in the world, but we can expect many unique and significant discoveries through the research of neuro-myo-arthro-kinetic ''apparatus'' in relation to cortical hemodynamic activity. It is also noteworthy that these studies may provide new insights into the potential clinical applications of NIR spectroscopy. In the conclusion fNIRS is a promising tool for optimizing the rehabilitation of patients whith cerebral palsy, offering an objective method for evaluation and guidance of treatment.
