The Mayo Elbow Performance Score (MEPS) is a rating system consisting of four dimensions to evaluate elbow performance. It is a common tool for assessment of elbow impairments worldwide. We determined the validity and reliability of its German version (MEPS-G) after cross-cultural adaptation.
Six investigators examined 57 patients with elbow pathologies. The MEPS-G was compared to validated elbow scores such as the German versions of DASH, the Oxford Elbow Score, pain level and subjective elbow performance on a VAS. Inter-rater reliability (IRR) and validity of the score and its dimensions were also reviewed. Verification was performed using the intraclass correlation coefficient (ICC), the prevalence and bias with adjusted Kappa (PABAK) and the Spearman correlation.
The IRR of the MEPS-G score was moderate (ICC (2.1) = 0.65). The IRR of the four individual dimensions was moderate to high (K = 0.55 -0.81). Validity for the sum score (r = 0.52-0.65) and the dimensions pain (r = 0.53-0.62), range of motion (r = 0.7) and stability (r = - 0.61) was verified. The function subscale reached insufficient validity (r = 0.15-0.39).
The MEPS-G is not sufficiently valid, which is consistent with its English version. The patient-based dimensions were a weakness, demonstrating high risk of bias. There is no general recommendation for the utilization of the MEPS-G as outcome measurement for patients with elbow pathologies.
Mayo 肘部功能评分（MEPS）是一个由四个维度组成的评分系统，用于评估肘部功能。它是一种全球通用的评估肘部损伤的工具。我们在经过跨文化调适后，确定了其德文版本（MEPS-G）的有效性和可靠性。
六位研究者检查了 57 例肘部病变患者。MEPS-G 与经过验证的肘部评分（如 DASH 的德国版本、牛津肘部评分、疼痛水平和 VAS 上的主观肘部功能）进行了比较。还评估了该评分及其各维度的组内相关系数（ICC）、信度和效度。
MEPS-G 评分的组内相关系数（ICC（2.1）=0.65）为中度。四个单项维度的组内相关系数为中度至高度（K=0.55-0.81）。总分（r=0.52-0.65）和疼痛（r=0.53-0.62）、活动范围（r=0.7）和稳定性（r=-0.61）维度的效度得到验证。功能子量表的效度不足（r=0.15-0.39）。
MEPS-G 的有效性不足，这与其英文版一致。基于患者的维度存在弱点，存在高度的偏倚风险。因此，不建议将 MEPS-G 作为肘部病变患者的结果测量工具。
