ABSTRACT

The problem of rehabilitation therapy for patients with ischemic strokes is very acute in modern neurology. Neurophysiologicalresearches are currently leading in the study and monitoring of the brain plasticity state. About 80% of all traumasassociated with ischemic stroke affects musculoskeletal system, and about half of them are upper limbs injuries. The effectivenessof treatment depends on adequacy of the first aid. After conservative methods of treatment, it reachs 13–60%, andafter the operation – from 10 to 70%. In addition, disability in patients with radial fractures is quite significant and rangesfrom 6 to 8 months, 10% of patients are forced to change their profession, and 6–17% become disabled. An integral part ofthe of the rehabilitation process in this group patients is dynamic electroencephalography (EEG), since information on the functional state of cerebral structures is necessary for a full rehabilitation program, prognosis and objective assessment oftreatment results. We examined 26 patients with cerebral stroke (14 men and 12 women aged 42–65 years) in the early recoveryperiod with spastic hemiparesis as a leading neurological syndrome and 27 patients with distal metaepiphysis radialfractures (after manual reposition and plaster splint removal), at various rehabilitation stages within a weekly interval.It was found that cerebral changes in electroactivity, assessed by similar leads of the contralateral hemisphere, are moreevident in stroke patients, that may be a peculiarity of cerebral rhythm during stroke, as there is more diffuse encephalographicpattern due to deep localization of alteration focus and pathways. Positive trends in the reduction of slow-waveactivity over the lesionare more evident in patients who were administed dynamic and static exercisesin the long-term recoveryperiod. Normalization of electrogenesis as a result of treatment is the most evident in patients who performed staticexercises than dynamic ones.
