Quadriceps weakness is associated with a poor prognosis in COPD. Several data suggest
that immobility and muscle wasting may be related through up-regulation of the p38 Mitogen …

Introduction COPD presents with an array of extra-pulmonary symptoms of which skeletal
muscle dysfunction, particularly of the quadriceps, is well recognized. This contributes to …

Quadriceps strength relates to exercise capacity and prognosis in chronic obstructive
pulmonary disease (COPD). We wanted to quantify the prevalence of quadriceps weakness …

Background: Quadriceps muscle weakness is common in chronic obstructive pulmonary
disease (COPD) but is not observed in a small hand muscle (adductor pollicis). Although this …

Quadriceps muscle weakness is an important component of chronic obstructive pulmonary
disease (COPD). We hypothesised that quadriceps weakness would also be a feature of …

Quadriceps weakness is an important complication of advanced chronic obstructive
pulmonary disease (COPD) but few data exist concerning muscle bulk in early disease. We …

Background Quadriceps muscle dysfunction is well confirmed in chronic obstructive
pulmonary disease (COPD) and reported to be related to a higher risk of mortality. Factors …

Quadriceps muscle weakness and increased fatigability are well described in patients with
chronic obstructive pulmonary disease (COPD). Whether these functional alterations also …

Muscle atrophy in chronic obstructive pulmonary disease (COPD) is associated with
reduced exercise tolerance, muscle strength, and survival. The molecular mechanisms …

It is well known that chronic obstructive pulmonary disease (COPD) patients present with
muscle dysfunction that may not correlate with the degree of severity of airflow obstruction …
