Background. Using external robotic tools in rehabilitation of patients after stroke could activate neuroplasticity mechanisms, thus reducing the ischemic area and improving the neurological outcome of the disease.Aim. To evaluate the effectiveness of early rehabilitation of stroke patients in Tomsk Regional Stroke Center using assistive robotic tools by correlational analysis of clinical and laboratory biomarkers of brain neuroplasticity.Materials and methods. The study included 68 patients who suffered from stroke of the middle cerebral artery. Early rehabilitation was carried out in Tomsk Regional Stroke Center using assistive robotic tools according to the protocol. Neurotrophic factors in blood serum were measured by the enzyme-linked immunosorbent assay. The severity of neurological disorders was characterized based on the Fugl – Meyer assessment scale (FMA).Results. The clinical effectiveness of early motor rehabilitation in Tomsk Regional Stroke Center is confirmed by the statistically significant increase on the FMA scale by 5.2 ± 2.4 points (p = 0.008). Positive association between neurotrophic factors in blood serum and FMA total score enables to consider the resulting data as an evidence of neuroplasticity activation associated with the use of robotic electromechanical technologies.
This literature review is devoted to the study of recent advances in the field of neurorehabilitation using robotic technologies. Objective: to study best practices of applying robotic rehabilitation technologies in stroke patients, its clinical efficacy and influence on the molecular mechanisms of neuroplasticity. Keywords were searched in the Web of Science, Core Collection, Scopus and PubMed databases.Results.Robotic neurorehabilitation occupies a certain place in the comprehensive rehabilitation of patients with motor deficiency after stroke. An interdisciplinary patient-oriented approach and consistency at all stages of medical rehabilitation are especially important when using rehabilitation methods that implement advances in robotics and information technologies in patients after stroke. Rehabilitation with the use of high-tech computerized rehabilitation systems operating in the biofeedback mode is one of the promising areas and requires further neurophysiological and laboratory studies to create scientifically based methodological approaches. It will have great social significance and tangible economic effects from improving the quality of neurorehabilitation and reducing its duration.
One of the main directions in the development of modern electroanalytical chemistry is the development of new effective methods for research and analysis of biological objects, particularly, human blood serum. The creation of new electrochemical sensors is a promising approach, which has determined several main directions in applied voltammetry in the field of chemical analytical control. In this work, the dynamics and parameters of total antioxidant activity of human serum blood of patients with chronic cerebral ischemia, during treatment with pharmaceutical drugs Mexidol, Cavinton Comfort, and Cytoflavin was tested by cathode voltammetry with a model process of oxygen electroreduction, using a new electrochemical sensor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
