Análise do equilíbrio bipodal de pessoas com doença renal crônica sob hemodiálise: comparação com idosos caidores e não caidores

Abstract

Among the main tissues affected by Chronic Kidney Disease (CKD) is skeletal muscle. Patients undergoing chronic hemodialysis experience loss of strength, muscle mass, and physical function, which contribute to the risk of falls. The objective of the study to assess the balance of individuals with CKD undergoing hemodialysis compared to fallers and non-fallers older adults. Methods: A cross-sectional and observational study was conducted with 99 participants among adults and older adults from the city of Governador Valadares, Minas Gerais, Brazil. The protocol followed the ethical principles of the Helsinki Declaration and was approved by the Research Ethics Committee of the Federal University of Juiz de Fora (number 74024123.3.0000.5147). Balance assessment was performed using the Balance Tracking System signal acquisition system. The Shapiro-Wilk test and Levene's test were used to assess data normality and homogeneity, respectively. The Kruskal-Wallis test was used to compare differences between groups. Bonferroni post hoc test was used for pairwise comparisons. Findings: There were significant differences between groups in age and weight. In comparing center of pressure displacement, the fallers group exhibited greater total center of pressure displacement, antero-posterior excursion, ellipse area formed by displacement, and velocity compared to non-fallers and renal patients. However, it is noteworthy that the Renal group had worse balance compared to the non-fallers older adults group. Interpretation: Fallers older adults demonstrate poorer postural balance compared to Chronic Kidney Disease patients undergoing hemodialysis.
