Substantiation and Standardization of the Multimodal Cognitive-motor Rehabilitation System for Afterstroke Patients

The aim of the study is to develop and scientifically substantiate a standardized system of multimodal cognitive-motor rehabilitation and its differentiated application in patients with cerebral stroke, according to verified rehabilitation potential based on the patient's rehabilitation model for the stages of medical rehabilitation, including inpatient-replacement technologies

The object of the study The study will include 405 patients (men and women) with the diagnosis of ischemic stroke (IS) in the acute (0-21 day), early recovery (up to 6 months) and late recovery (6-12 months) periods with stato-locomotor disturbances, dysfunction (violation of neuromuscular movement control) of the upper limb (UL), lower limb (LL), mild or moderate cognitive impairment.

Patients will be randomly assigned to one of 6 experimental groups - 3 main groups of 70 patients each in the acute, early and late recovery period of IS and 3 comparison groups (each of 65 patients) in the acute, early and late recovery periods of IS. The patients in the main and comparison groups will be comparable in age, gender and symptoms.

Each participant of the study will be assigned an ordinal number. Patients of the main groups are planned to undergo a rehabilitation course with standardized multimodal correction, depending on the severity of functional and neuropsychological disturbances with the use of FBF-stabilometric training, cognitive-motor training with double and triple tasks in a virtual environment, functional individually programmed stimulation of antagonist muscles of the lower limb (FES), training of subject-manipulative activity for the restoration of fine hand movements on the glove simulator "SensoRehab"; when severe and moderate paresis of the upper limb, the neurointerface "Exokist-2" with EEG registration will be used.

The patients of comparison groups are planned to undergo a rehabilitation course with standart rehabilitation programms depending on the severity of functional and neuropsychological disturbances: kinesiotherapy, physical therapy, occupational therapy, massage.

The study is carried out at the inpatient stage, then patients are transferred to the outpatient stage of rehabilitation or controlled home self-rehabilitation using telemedicine technologies.

The mode of application of multimodal correction technology:

inpatient stage: 10 procedures every day (5 working days, 2 days the rest);the total duration of one procedure is 2-3 hours a day.

outpatient stage: 15 procedures, 2-3 times a week, the duration of the course is 5-8 weeks. The total duration of one procedure is 2-3 hours a day.

Multimodal correction technology will not be included in the rehabilitation program of patients in the comparison group.
