Cortical propagation tracks functional recovery after stroke
In conclusion, our new spatiotemporal propagation indicators could represent promising biomarkers that are able to uncover neural correlates not only of motor deficits caused by stroke but also of functional recovery during rehabilitation. In turn, these insights could pave the way tow ards more targeted post-stroke therapies.

The beneficial role of early exercise training following stroke and possible mechanisms
Publication date: 1 April 2018 Source:Life Sciences, Volume 198 Author(s): Ying Xing, Si-Dong Yang, Fang Dong, Man-Man Wang, Ya-Shuo Feng, Feng Zhang Exercise training is a regular therapy for stroke patients in clinic. However, whether the early exercise is beneficial for stroke patients is still controversial. The review was performed in databases of OVID, PUBMED, and ISI Web of Science, from respective inception to December 2017. In this review, we summarize the effect of different exercise intensity, initiation time, and style on ischemic stroke. Moreover, the possible mechanism is also discussed. The conclusion is th...

High intensity exercise preconditioning provides differential protection against brain injury following experimental stroke
Publication date: Available online 6 March 2018 Source:Life Sciences Author(s): Rasoul Rezaee, Sanaz Nasoohi, Abbas Haghparast, Fariba Khodagholi, Mohammadreza Bigdeli, Maryam Nourshahi Aims Different modes of physical activity provide cerebrovascular protection against thromboembolic events. Based on recent reports high intensity exercise protocols appear to raise cerebral VEGF levels leading to efficient cerebral angiogenesis. The present study aims to address if moderate continuous training (MCT) and high intensity interval training (HIT) differ in preconditioning against ischemic stroke. Methods Wistar rats were subje...

Fuzzy cognitive map based approach for determining the risk of ischemic stroke
In this study, the soft computing method known as fuzzy cognitive mapping was proposed for diagnosis of the risk of ischemic stroke. Non-linear Hebbian learning method was used for fuzzy cognitive maps training. In the proposed method, the risk rate for each person was determined based on the opinions of the neurologists. The accuracy of the proposed model was tested using 10-fold cross-validation, for 110 real cases, and the results were compared with those of support vector machine and K-nearest neighbours. The proposed system showed a superior performance with a total accuracy of (93.6 ± 4.5)%. The da...

Dynamics of fMRI and EEG Parameters in a Stroke Patient Assessed during a Neurofeedback Course Focused on Brodmann Area 4 (M1)
A course of interactive stimulation of primary motor cortex (Brodmann area 4) in the brain of a stroke patient resulted in recovery of locomotion volume in the paretic extremities and in improvement of general health accompanied with diverse changes in cerebral activity. During the training course, the magnitude of response in the visual fields of Brodmann areas 17 and 18 decreased; in parallel, the motor areas were supplemented with other ones such as area 24 (the ventral surface ofanterior cingulate gyrus responsible for self-regulation of human brain activity and implicated into synthesis of tactile and special informat...

Prospects of Synchronous fMRI-EEG Recording as the Basis for Neurofeedback (Exemplified on Patient with Stroke Sequelae)
Synchronous fMRI-EEG mapping of cerebral activity in stroke patients made it possible to implement neurofeedback, a novel and promising therapeutic technology. This method integrates a real-time monitoring of cerebral activity by EEG and fMRI signals and training of the patients to control this activity simultaneously or alternatively via neurofeedback. The targets of such cerebral stimulation are cortical regions controlling arbitrary movements (Brodmann area 4), whereas its aim is optimization of activity in these regions in order to achieve better rehabilitation of stroke patients. The paper discusses the methodical det...

Kessler Foundation researchers find foot drop stimulator beneficial in stroke rehab
(Kessler Foundation) Kessler Foundation scientists have published a study showing that use of a foot drop stimulator during a task-specific movement for 4 weeks can retrain the neuromuscular system. This finding indicates that applying the foot drop stimulator as rehabilitation intervention may facilitate recovery from this common complication of stroke. 'EMG of the tibialis anterior demonstrates a training effect after utilization of a foot drop stimulator,' was published online ahead of print on July 2 by NeuroRehabilitation

Daily variation in time-trial sporting performance: A systematic review
Chronobiol Int. 2022 Jul 11:1-16. doi: 10.1080/07420528.2022.2090373. Online ahead of print.ABSTRACTFew functional measures related to time-trial display diurnal variation. The diversity of tests/protocols used to assess time-trial performance on diurnal effects and the lack of a standardised approach hinder agreement in the literature. Therefore, the aims of the present study were to investigate and systematically review the evidence relating to time-of-day differences in time-trial measures and to examine the main aspects related to research design important for studies of a chronobiological nature. The entire content of...
