Validation of Functional Fitness Tests as Surrogates for Strength Measurement in Frail, Older Adults with Chronic Obstructive Pulmonary Disease

Abstract

Only the Arm Curl and Chair Stand tests were valid surrogates. Although multiple field tests to measure strength in a clinical setting may be desirable, these data support limiting functional testing to the Arm Curl for upper-body and the Chair Stand for lower-body strength assessment.
