Minimal important difference of quadriceps maximal voluntary contraction (QMVC) in COPD: a prospective cohort study
Key Points
Changes in quadriceps maximal voluntary contraction should be interpreted using specific minimum important difference estimates.
Sex-specific estimates are vital for proper assessment of quadriceps strength in individuals with COPD.
This study employed a prospective cohort approach to gather data on quadriceps strength changes over time.
Identifying these differences may enhance personalized treatment strategies for patients with COPD.
Abstract
We provide MID estimates for QMVC parameters. Sex-specific or normalised MID estimates for QMVC should be used to facilitate the interpretation of change.
