The effect of hemodialysis on balance measurements and risk of fall.

In the current study, we evaluated the balance of ESRD patients before and after a routine session of hemodialysis treatment. This is the first study to investigate the effect of hemodialysis on balance, using an electronic posturographic balance system. We found the Fall Index score to be significantly higher after hemodialysis, indicating a negative effect of hemodialysis on postural stability. As expected, our data showed an increased Fall Index score correlated with the increase in age both in ESRD patients and in healthy controls. However, the correlation with age was not observed for the patient group at the post-dialysis balance measurement. We might conceive that young patients with ESRD are also prone to fall risk after a session of hemodialysis. Methods that provide quantitative assessment for fall risk could be rather beneficial for high-risk populations such as patients on maintenance hemodialysis.
