What is a Clinically Meaningful Improvement in Leg-Extensor Power for Mobility-limited Older Adults?

摘要

Background:Muscle power is a key predictor of physical function in older adults; however, clinically meaningful improvements in leg-extensor muscle power have yet to be identified. The purpose of this study is to establish the minimal clinically important improvement (MCII) and substantial improvement (SI) for leg-extensor power and muscle contraction velocity in mobility-limited older adults.
