英国医学研究理事会肌力测试在重症监护室患儿中的评定者间信度

Inter-rater reliability of Medical Research Council muscle strength test in pediatric intensive care unit

目的确定英国医学研究理事会(MRC)肌力测试应用于危重症儿童的评定者间信度。方法选择2022年6月至2023年3月在复旦大学附属儿科医院重症监护室住院的2~12岁危重症患儿41例,由两名治疗师分别对患儿进行MRC肌力测试。结果MRC总分评定者间信度良好(ICC=0.788,95%CI 0.636~0.881,P<0.001),上、下肢MRC总分信度良好至极好(ICC=0.641~0.803,95%CI 0.419~0.890,P<0.001);对≥7岁儿童,MRC总分信度极好(ICC=0.855,95%CI 0.692~0.935,P<0.001)。结论MRC肌力测试在危重症患儿人群中具有满意的评定者间信度,对学龄儿童信度可能更好。

Objective To investigate the inter-rater reliability of Medical Research Council(MRC)muscle strength test in critically ill children.Methods From June,2022,to March,2023,41 critically ill children aged two to twelve years were involved from the Pediatric Intensive Care Unit of Children's Hospital of Fudan University.Two physiotherapists implemented MRC muscle strength tests separately.Results MRC total score was good in inter-rater reliability(ICC=0.788,95%CI 0.636 to 0.881,P<0.001),as well as both the scores of upper limbs and lower limbs(ICC=0.641 to 0.803,95%CI 0.419 to 0.890,P<0.001).For children more than seven years old,MRC total score was excellent in inter-rater reliability(ICC=0.855,95%CI 0.692 to 0.935,P<0.001).Conclusion MRC muscle strength test is good in inter-rater reliability for critically ill children,especially for school-age children.
