Biosensors, Journal Year: 2021, Volume and Issue: 11(10), P. 389 - 389

Published: Oct. 13, 2021

Functional Near-Infrared Spectroscopy (fNIRS) is a wearable optical spectroscopy system originally developed for continuous and non-invasive monitoring of brain function by measuring blood oxygen concentration. Recent advancements in brain-computer interfacing allow us to control the neuron combining it with fNIRS regulate cognitive function. In this review manuscript, we provide information regarding current advancement how provides advantages developing enable We also briefly discuss about can use technology further applications.

Cerebral and muscle tissue oxygenation during exercise in healthy adults: A systematic review

Journal of sport and health science/Journal of Sport and Health Science, Journal Year: 2024, Volume and Issue: 13(4), P. 459 - 471

Published: March 8, 2024

Near-infrared spectroscopy (NIRS) technology has allowed for the measurement of cerebral and skeletal muscle oxygenation simultaneously during exercise. Since this been growing is now successfully used in laboratory sports settings, systematic review aimed to synthesize evidence enhance an integrative understanding blood flow adjustments oxygen changes (i.e., balance between (O2) delivery O2 consumption) within systems A was conducted using PubMed, EMBASE, Scopus, Web Science databases search relevant studies that investigated hemodynamics NIRS system This considered manuscripts written English available before February 9, 2023. Each step screening involved evaluation by 2 independent authors, with disagreements resolved a third author. The Joanna Briggs Institute Critical Appraisal Checklist assess methodological quality studies. Twenty were included, which 80% had good quality, 290 young or middle-aged adults. Different types exercises hemodynamic changes, such as cycling (n = 11), treadmill 1), knee extension 5), isometric contraction biceps brachii 3), duet swim routines 1). analysis focused on frontal cortex 20), while muscle, vastus lateralis 18), gastrocnemius deltoid intercostal Overall, deoxygenation increases exercise, reaching plateau voluntary exhaustion, brain, oxyhemoglobin concentration exercise intensity, declining at exhaustion point.

The Contribution of Functional Magnetic Resonance Imaging to the Understanding of the Effects of Acute Physical Exercise on Cognition

Brain Sciences, Journal Year: 2020, Volume and Issue: 10(3), P. 175 - 175

Published: March 18, 2020

The fact that a single bout of acute physical exercise has positive impact on cognition is well-established in the literature, but neural correlates underlie these cognitive improvements are not well understood. Here, use neuroimaging techniques, such as functional magnetic resonance imaging (fMRI), offers great potential, which just starting to be recognized. This review aims at providing an overview those studies used fMRI investigate effects exercises cerebral hemodynamics and cognition. To this end, systematic literature survey was conducted by two independent reviewers across five electronic databases. search returned 668 studies, 14 met inclusion criteria were analyzed review. Although findings reviewed suggest (e.g., cycling) leads profound changes brain activation, small number available variability study protocols limits conclusions can drawn with certainty. In order overcome limitations, new, more well-designed trials needed (i) rigorous design, (ii) apply sophisticated filter methods data analysis, (iii) describe applied processing steps analysis detail, (iv) provide precise prescription.

Transcranial direct current stimulation combined with physical or cognitive training in people with Parkinson’s disease: a systematic review

Journal of NeuroEngineering and Rehabilitation, Journal Year: 2020, Volume and Issue: 17(1)

Published: June 15, 2020

Abstract Background Pharmacologic therapy is the primary treatment used to manage Parkinson’s disease (PD) symptoms. However, it becomes less effective with time and some symptoms do not respond medication. Complementary interventions are therefore required for PD. Recent studies have implemented transcranial direct current stimulation (tDCS) in combination other modalities of interventions, such as physical cognitive training. Although tDCS training seems promising, existing present mixed results. Therefore, a systematic review literature necessary. Aims This aims (i) assess clinical effects when applied or therapies people PD and; (ii) analyze how specific details intervention protocols may relate findings. Methods The search strategy detailed technique stimulation, population combined (i.e. and/or training). Only controlled were included. Results Seventeen an initial yield 408 satisfied criteria. Studies involved small sample sizes. characteristics varied. reviewed suggest that synergistic be obtained cognition, upper limb function, gait/mobility posture motor Conclusion reported results encourage further research better understand therapeutic utility inform optimal use Future this field should focus on determining parameters maximal benefits
