Severe and early quadriceps weakness in mechanically ventilated patients
Sedation condition, RASS score −3.8 ± 1.5 ICU-acquired weakness has been reported in patients with prolonged mechanical ventilation [1], leading to prolonged weaning, poor quality of life after ICU discharge, and high ICU-related cost [2]. Muscle weakness is the primary manifestation of critical illness polyneuropathy or myopathy or both. Although quadriceps strength has never been objectively ...
متن کاملQuadriceps weakness in a family with nemaline myopathy: influence of knee angle.
Nemaline myopathy is a congenital neuromuscular disorder, which primarily affects the thin filaments. Clinically the most important feature is muscle weakness; however, this weakness is poorly understood. The present investigation aimed to determine the torque angle relationship of the knee extensor muscles during in vivo muscle contractions in a family with a novel phenotype of nemaline myopat...
متن کاملThe prevalence of quadriceps weakness in COPD and the relationship with disease severity.
Quadriceps strength relates to exercise capacity and prognosis in chronic obstructive pulmonary disease (COPD). We wanted to quantify the prevalence of quadriceps weakness in COPD and hypothesised that it would not be restricted to patients with severe airflow obstruction or dyspnoea. Predicted quadriceps strength was calculated using a regression equation (incorporating age, sex, height and fa...
متن کاملThe mechanism of quadriceps femoris weakness in patients with ruptured and reconstructed ACL
Introduction There is ample evidence that the anterior cruciate ligament (ACL) has a sensory function. Previous studies reported that afferent feedback from ACL contributed to increased tone of the muscles around the knee. However, it is unlikely that afferent feedback from ACL directly alter a motor neuron (MN); afferents from ACL could influence a motor neuron (MN) via the ? loop. Therefore, ...
متن کاملPrevalence of quadriceps muscle weakness in patients with COPD and its association with disease severity
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 impaired quality of life and increased health care utilization. Work on the quadriceps originated from the observation that a good proportion of COPD patients stop exercise due to the feeling of leg fatigue rather than...
