Pathophysiology of balance disorders due to multiple sclerosis (MS) and atrial vertigo (AV) is different. We evaluated posture stability when maintaining balance in people with MS presenting symptoms of ataxia and those with AV. We included 45 women (15 with MS; 15 with AV; 15 controls). A posturography platform was used to measure balance parameters. To characterize the image of stability and the compensation of balance disorders, the surface area of the stabilogram (SAS), vision control index (VCI) and the vision-motion control index (VMCI) were used. The stability image of people with MS and AV with eyes open (p = 0.002), with eyes closed (p = 0.080) and with visual biofeedback (p = 0.0008) differed significantly. SAS depended on visual biofeedback regardless of the occurrence of balance disorders and was the basis for determining the compensatory share of vision-motor coordination. Differences in VCI between groups were insignificant. VMCI was significantly higher in people with balance disorders than in those without, but similar in the MS and AV groups. The image of stability is different in people with MS and AV. Thanks to visual biofeedback, it becomes possible to launch effective vision-motor coordination when compensating balance disorders. VCI may become the measure of compensation for balance disorders.

Multiple sclerosis (MS) is a chronic progressive neurological disease with a characteristic myelin sheath loss and consequent progressive neurological disorders. The latest statistics, published by the Multiple Sclerosis International Federation, show that around the world people with MS are about 2.3 million, and most are from 20 to 40 years old. In Poland, it is estimated that 40-60,000 people suffer from multiple sclerosis. Until recently, people with MS were advised not to exercise. It was dictated that physical activity causes, among other things, an increase in body temperature, but this may contribute to the severity of the symptoms of the disease. However, lack of physical activity is conducive to lowering exercise tolerance and muscle weakness. Polish Society of Multiple Sclerosis promotes movement in patients with MS. Researchers point out that people with MS have lower levels of physical activity than in the general population, which aggravates motor impairment and negatively affects the quality of life of MS patients. The assessment of the quality of life of people with MS is largely influenced by both motor disability factors and socio-demographic or clinical factors. The disease negatively affects most areas of life, which contributes to a significant deterioration in its quality. It should be noted, however, that there is a greater tendency to deteriorate the quality of life in the physical dimension than in the mental one. The duration of SM does not affect the level quality of life, and with the duration of the disease, the disease is accepted by patients with MS. Elderly patients with progressive disease, less active and untreated, are significantly less likely to report quality of life than those younger, with a cast-off, lower EDSS score and treated. People who are more adept at ADL activities show higher quality of health in the social and social fields. Rehabilitation strategies, fatigue and sleep disorders, as well as cognitive functions, are analyzed in order to understand the underlying mechanisms and to identify the most effective therapeutic approaches. The study of the relationship between individual and clinical factors of people with multiple sclerosis with selected components of the quality of life can be used to model the patients’ illnesses and the course of the disease.
