肌无力通常会使危重疾病复杂化，并与毁灭性的短期和长期后果有关。对于介入研究，需要对重症监护室（ICU）中的肌肉力量进行可靠的测量。研究方法：为了检验观察者之间的一致性，两名观察者独立测量了ICU横断面样本中的医学研究理事会（MRC）总分（n = 75）和握力（n = 46）。结果：MRC总分的组内相关系数（ICC）为0.95（0.92 ± 0.97）。识别显著弱点的kappa系数（MRC总分
Introduction: Muscle weakness often complicates critical illness and is associated with devastating short- and long-term consequences. For interventional studies, reliable measurements of muscle force in the intensive care unit (ICU) are needed. Methods: To examine interobserver agreement, two observers independently measured Medical Research Council (MRC) sum-score (n = 75) and handgrip strength (n = 46) in a cross-sectional ICU sample. Results: The intraclass correlation coefficient (ICC) for MRC sum-score was 0.95 (0.920.97). The kappa coefficient for identifying significant weakness (MRC sum-score
