ANALYSIS OF RELATIONSHIP BETWEEN POSTURAL STABILITY AND DEGREE OF VISUAL IMPAIRMENT

The aim of study was to evaluate the postural stability in patients with various degree of visual impairment. Statistical analysis of influence of degree of visual impairment on postural stability opposed to people perfectly sighted also was conducted. The studies was conducted on 30 patients with various degree of visual impairment and 10 patients perfectly sighted. Postural stability was tested using two diagnostic machines. The patient stood in its habitual position with its arms lowered along its body and its feet spacing on hip width. In this position were done some tests, where patients were obligated to adopt two positions their bodies in variants with opened and closed eyes. Next, the stabilographic parameters were measured. Conducted statistical analysis of results from research allows to propose a conclusion that there is significant statistical dependence between degree of eyesight dysfunction and ability to maintain stable posture. The conducted researches revealed the influence of lack of visual control on increase of most of stabilographic parameters values.
