Relationship between functional capacity, dynamic and static muscle function assessments in people with Chronic Obstructive Pulmonary Disease (COPD)

Supplement: 62Meeting Abstract: PA4154
Introduction: In addition to impaired lung function, patients with COPD often exhibit limb muscle dysfunction and impaired functional status, negatively impacting quality of life. However, whether and how these two components related to each other remains to be established. The objective of this study was to examine relationships between quadriceps muscle function and functional capacity in patients with COPD.Methods: Forty participants (age :69±7 years, FEV1 :57±18 % predicted) were evaluated. Quadriceps strength was measured during isometric and isokinetic knee extension while quadriceps endurance was evaluated using isometric, isokinetic and isotonic knee extension protocols. Functional capacity was assessed with a battery of test including the 6 minute walking test (6MWT), the ADL Glittre test, the 1 minute Sit to Stand (1STS) and the Short Physical Performance Battery test (SPPB). Univariate correlation analyses between indices of muscle strength and endurance and functional tests were performed.Results: Pearson correlations coefficients between functional capacity and quadriceps function are provided in the table.Conclusion: Several indices of muscle function moderately correlate with functional capacity in patients with COPD, with stronger correlations noted for the dynamic contraction protocols (isokinetic, isotonic).
