Abstract


Background. Stroke and osteoporosis are age-dependent pathologies that affect elderly people mostly. The purpose of the study was to evaluate the features of bone mineral density (BMD) in stroke patients. Materials and methods. We examined 84 stroke patients and 124 persons of the corresponding age and sex without neurological pathology, who made up the comparison group. The activities of daily living were determined by the Barthel index. Results. The frequency of osteoporosis was significantly higher in stroke patients than in the comparison group (16.7 versus 4.0 %). BMD in stroke women was significantly lower at all levels, in men differences are recorded at the level of radius 33% and total body. With an increase in the length of the post-stroke period, men had a decrease in BMD at the level of the femoral neck (F = 3.12; p = 0.038) and radius 33% (F = 3.26; p = 0.034), in women — at the level of all surveyed sites. Correlations were recorded between the Barthel index and BMD at the level of the lumbar spine (r = 0.37, p < 0.05), femoral neck and proximal femur (r = 0.30, p < 0.05 and r = 0.26, p < 0.05), at the level of the upper and lower extremities (r = 0.27, p < 0.05, r = 0.32, p < 0.05), as well as at the total body and radius 33% (r = 0.33, p < 0.05, r = 0.38, p < 0.05). A model has been created for predicting the development of osteoporosis in stroke patients, taking into account the parameters of body mass, the duration of the post-stroke period and the total Barthel index. Conclusions. The results of our study show that stroke is a risk factor for the development of osteoporosis. The degree of bone loss depends on the functional deficit, the duration of the post-stroke period, and has gender features.
