To test the reliability of the Mayo Elbow Performance Score (MEPS) and compare it with a validated outcomes instrument, the American Shoulder and Elbow Surgeons (ASES) score.
A total of 42 patients with the chief problem of elbow dysfunction formed the study cohort. Patients with an immediate surgical indication or treatment at the index visit were excluded. The others completed an MEPS questionnaire; at a second visit 2 to 3 weeks later, they completed another MEPS questionnaire and were evaluated with the ASES elbow assessment. Reliability and accuracy were calculated using 2-tailed Pearson correlation coefficients with 95% confidence intervals. Pearson coefficients greater than 0.8 indicated strong agreement.
The average MEPS score at the initial visit was 58. At the second visit, the average MEPS score was 69 and the average ASES score was 78. The Pearson coefficient for MEPS scores at the 2 time points averaged 0.82, and between the MEPS and ASES scores averaged 0.83. Both coefficients indicated strong agreement.
The MEPS has strong reliability when assessed at different times and when compared with a validated elbow outcomes instrument. Differences in compared scores of approximately 10 points indicate some patient improvement between time points; however, 95% confidence intervals, standard deviations, and ranges were essentially equivalent between and among tests, indicating similar accuracy.
The MEPS is a reliable outcomes instrument for clinical studies of elbow function that is used to assess nonsurgical treatment.
测试梅奥肘关节功能评分（MEPS）的可靠性，并将其与经过验证的结果评估工具——美国肩肘外科医师学会（ASES）评分进行比较。
共有42例以肘关节功能障碍为主要问题的患者组成研究队列。排除在首次就诊时有立即手术指征或接受治疗的患者。其余患者完成一份MEPS问卷；在2至3周后的第二次就诊时，他们完成另一份MEPS问卷，并接受ASES肘关节评估。使用双侧Pearson相关系数及95%置信区间计算可靠性和准确性。Pearson系数大于0.8表示高度一致。
首次就诊时MEPS平均评分为58分。第二次就诊时，MEPS平均评分为69分，ASES平均评分为78分。两个时间点的MEPS评分的Pearson系数平均为0.82，MEPS与ASES评分之间的Pearson系数平均为0.83。两个系数均表示高度一致。
MEPS在不同时间进行评估以及与经过验证的肘关节结果评估工具进行比较时，具有很强的可靠性。比较评分相差约10分表明两个时间点之间患者有一定改善；然而，各测试之间及测试内部的95%置信区间、标准差和范围基本相当，表明准确性相似。
MEPS是一种用于评估非手术治疗的肘关节功能临床研究的可靠结果评估工具。
