Evaluation of the pressure distribution on force platform in patients after cerebral stroke
Journal Title: Rehabilitacja Medyczna - Year 2005, Vol 9, Issue 1
Abstract
Introduction: Hemiparesis, coexistence of disturbances of deep sensation and balance affect the patients’ performance after stroke. The aim of the study was to evaluate the usefulness of a force platform for measurig the distribution of lower extremities pressure force and the effect of hemiparesis on the change of the distribution of pressure force shifted by lower extremities on the base in a standing position in the patients after the first stroke.Material and methods: The study comprised 23 patients with and 16 patients without hemiparesis (a control group). ERBE force platform with a computer program for Windows Physio-Feedback-System was used for the measurement of the pressure.Results: Mean pressure force of lower extremities in the subjects without hemiparesis was found to distribute symmetrically and is 0.5 ±0.07 for each extremity. In the patients with hemiparesis no statistically significant difference was found between the relative pressure force on the base by the paretic extremity in the patients with left and right hemiparesis (p = 0.568); the pressure force of the extremity on the side of the paresis is from 0.11 to 0.30 of total pressure.Conclusions: Force platform allows for objective evaluation of the state of human body balance by measuring the pressure force on the base. It may be applied in tests of patients with hemiparesis. Relative pressure force shifted by an extremity on the side of the paresis doses not depend on the side of the paresis. The stroke victims with hemiparesis tend to load the lower limb on the paretic side to a lesser degree.
