POSTURAL CONTROL OF PATIENTS WITH HEMIPARESIS AT DIFFERENT STAGES OF EARLY RECOVERY PERIOD FOLLOWING ISCHEMIC STROKE
Main Article Content
Abstract
Ischemic stroke is a serious disease which often leads to a violation of postural regulation.
Objective – to analyze the dynamics of postural regulation of patients with hemiparesis at different stages of the early recovery period of ischemic stroke.Material and methods. 14 patients in early and transitional recovery periods following ischemic stroke were examined. A clinical neurological examination and Romberg test using computerized stabilograph were conducted. We analyzed ellipse area; length of statokinesiogram; speed and displacement of common pressure center; standard deviation of pressure center; 60% of spectrum in coronal and sagittal planes; Romberg coefficient.
Results. Primary research observations: patients’ bodies swayed, the swaying increased after patients closed eyes; rotation of shoulder and pelvic girdle are in opposite directions; head and torso are tilted forward. Area of the statokinesiogram, standard deviation in coronal plane and frequency of oscillations exceeded the norm. After patients closed their eyes, all of the listed features increased.
Secondary research observation: asymmetry of the pose remains; displacement of the total center of pressure in the coronal plane has increased. The rest of the stabilogram parameters were close to the norm. Closing of the eyes was accompanied by approach of the general center of pressure to the center of the reference contour in the coronal plane.
Conclusion. At the very beginning of the early recovery period following ischemic stroke (day 8), the area of the statokinesiogram, the RMS deviation in the coronal plane, and the frequency of oscillations of patients are increased. Visual deprivation is accompanied by a displacement of the center of pressure in the coronal plane. In the future, after 1 month, patients stood more confidently, but the displacement of pressure center in coronal plane increased. Closing of the eyes is accompanied by approaching the position of the center of pressure to the middle of the support contour.
