The Association Between the Probability of Sarcopenia and Functional Outcomes in Older Patients Undergoing In-Hospital Rehabilitation.

Sarcopenia is a geriatric syndrome with a prevalence ranging from 5% to 50% in community-dwelling adults. It is associated with adverse outcomes including worse functional status, falls, and mortality. A paucity of studies have included an assessment of sarcopenia among older adults receiving in-hospital rehabilitation. This is, at least partially, due to the lack of simple assessment methods to reliably measure muscle mass. The objective of this study was to evaluate the probability of sarcopenia using a validated simple method and examine the association between sarcopenia and functional outcomes at discharge.
