The article presents an overview of innovative technologies based on the methods of sensorimotor retraining of patients using virtual reality technology as a promising in the comprehensive rehabilitation of patients who have suffered a cerebral stroke. High level of evidence studies (RCTs, meta-analyses, and systematic reviews) index in the PubMed, Cochrane Library, ClinicalTrials.gov databases are analyzed. Training with multisensory effects on visual, auditory, vestibular, and kinesthetic analyzers in multitasking conditions have beneficial effects on cognitive and motor training, retraining, neuropsychological status of the patien,t and an increase in the level of motivation to achieve success in the rehabilitation. The synergistic nature of the multimodal effects of virtual reality makes it possible to expand the possibilities and increase the effectiveness of medical rehabilitation in patients who have undergone cerebral stroke.
Cerebral stroke (CS) remains the most important medical and social problem. According to available data, only 25% of stroke survivors return to the premorbid level of daily or work activity, most patients have residual neurological disorders of varying severity. Effective rehabilitation of patients with CS requires not only timely initiation of treatment, but also an individual choice of rehabilitation program. To optimize the rehabilitation strategy in each case, it is necessary to set goals and objectives taking into account the rehabilitation potential (RP) and the prognosis of the patient’s recovery. This paper provides a definition of RP and ways to describe it. The existing neurophysiological methods for assessing the RP of functional recovery after CS, such as electroencephalography, evoked potentials and diagnostic transcranial magnetic stimulation (TMS), are considered. Information about neuroimaging diagnostic methods – computer (CT) and magnetic resonance imaging (MRI) in the context of determining RP is presented. The possibilities of functional and diffusion-t ensor MRI of the brain for assessing RP in various periods of the disease are highlighted in detail. Other possible predictors of the restoration of impaired functions are also considered – the volume and localization of the brain lesion, the patient’s age, cognitive functions and laboratory parameters. Modern complex approaches to the formation of algorithms for the quantitative assessment of RP are described. In particular, the current algorithms for evaluating RP – PREP2 for the upper limb and TWIST for predicting the recovery of walking disorders are described. Currently, there are no generally accepted methods for determining and quantifying RP. The instruments proposed for this purpose are insufficiently sensitive and specific or are not suitable for routine clinical practice.
INTRODUCTION. The prevalence of upper limb dysfunction and cognitive impairments are frequently observed following stroke, but are often considered as distinct entities, and there is little evidence regarding how they are related, as well as rehabilitation methods are aimed at monodomain restoration of any of these impairments.
AIM. To analyze the data of recent years on the impact of rehabilitation interventions on cognitive and the upper limb (UL) motor functions in patients with stroke, and to establish how they are related.
MATERIAL AND METHODS. The search was carried out in the Medline, Web of Science, PubMed and Scopus sources in accordance with the PRISMA principles and initially revealed 2,841 records. Of these, 35 articles were included in the study with publication 2011–2022. Keywords were used: stroke, movement, motor, upper limb, cognition, cognitive, cognitive-motor, motor-cognitive function. The relationship between cognitive impairments and the degree of restoration of the UL motor function under the influence of various rehabilitation interventions was assessed.
RESULTS. Five studies were selected for meta-analysis with the inclusion of 180 stroke patients. It is shown that the improvement of cognitive tests (MoCA) is accompanied by an improvement in UL motor impairments (FMA, Jebsen-Taylor Hand Function Test), while hand dexterity (Box and blocks, NHPT, Minnesota manual dexterity test) remained without statistically significant changes during medical rehabilitation.
CONCLUSION. The meta-analysis provides evidence of the relationship and mutual influence of cognitive functions on motor recovery and manual dexterity. However, the small sample size and heterogeneity of available studies are still limiting factors for obtaining unambiguous conclusions.
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.
