Correlations of Body Composition Measures with Functional Outcomes and the Clinical Frailty Scale in Inpatient Rehabilitation: a Prospective Cohort Study

The investigators are investigating if body composition measures - in particular muscle mass, body fat, and something called the phase angle - are able to reliably predict functional outcomes for patients who are in an acute hospital for inpatient rehabilitation. The investigators also want to see if age and frailty affect these relationships. Patients undergoing inpatient rehabilitation in our hospital will be monitored through a variety of frailty-specific tools, including strength and speed. The investigators will use a device called a body composition monitor (BCM) to record their body composition measurements. These will then be compared against their usual rehabilitation outcomes. The investigators believe that there is a correlation between these measures and a patient's functional outcomes.
