- Target number of participants80
- InterventionsMuscle strength will be investigated by the attending physiotherapist, using the Medical Research Council (MRC) sumscore to assess the presence of ICU-AW. Next, blinded to the strength evaluation, neuromuscular ultrasound examination will be performed.
- Primary outcomeDifference in gray-scale value as measures of echointensity on standardized cross-sectional ultrasonographic views of five muscle groups in patients with ICU-AW and patients without ICU-AW.
- Secondary outcome- Differences in standard deviation of the gray scale values as a measure of homogeneity of the five muscle groups between patients with ICU-AW and patients without ICU-AW.
- Differences in cross-sectional muscle thickness as measure of muscle atrophy of the five muscle groups between patients with ICU-AW and patients without ICU-AW.
- Differences in area and vascularity on standardized ultrasonographic views of median nerve and peroneal nerve.
- TimepointsSingle timepoint for neuromuscular ultrasound just after valid muscle strength assessment

- Brief summaryIntensive Care Unit-acquired weakness (ICU-AW), a frequently occurring complication of critical illness. Ultrasound examination of the neuromuscular system has been shown to improve diagnostic accuracy in various neuromuscular diseases. However, diagnostic accuracy of ultrasound examination for ICU-AW has not been investigated.
The aim of this study is to evaluate whether neuromuscular ultrasound discriminates between patients with and without ICU-AW. In this prospective cross-sectional survey, adult patients admitted to the ICU of the Academic Medical Center, who require mechanical ventilation for at least two days, will be included. The presence of ICU-AW will be assessed by the attending physiotherapist, using the Medical Research Council score. Thereafter, an extensive neuromuscular ultrasound examination will be performed.
The main study endpoint is the difference in gray-scale value, as measures of echointensity, on standardized cross-sectional ultrasonographic views of five muscle groups in patients with ICU-AW and patients without ICU-AW.
