Respiratory and Quadriceps Muscle Fatigability After an ICU Acquired Weakness

Comparison Between Respiratory and Quadriceps Muscle Fatigability During a Maximal Loading for ICU Weakness Patients

Muscle dysfunction can be lead to poor outcomes moreover ICU muscle weakness recovery are not correctly described.

The investigators aimed to assess the ability for quadriceps or respiratory muscles to repeat an effort at a maximal loading.
