摘要

背景:患者评价的网球肘评估(PRTEE),握力疼痛,无痛,最大握力是网球肘广泛使用的结果。本研究采用前瞻性测试-再测试研究设计来检验测量特性。方法:选取100例网球肘患者。评估信度、内部一致性、效度、反应性和最小重要变化(MIC)。结果:各项测量的信度均可接受。8/15的PRTEE项目低于内容效度标准。对于PRTEE总分(0-100),最小可检测变化95% (SDC95%)为17分,疼痛和功能亚量表(0-50)为8分和12分。对于抓握疼痛(0-10),SDC95%为4,无痛握力为6.4 kg,最大握力为8.4 kg。PRTEE总分MIC为9分,疼痛评分为11分,功能评分为4分。握力疼痛的MIC为3.5,无痛握力和最大握力的MIC为6.5 kg和1 kg。PRTEE、无痛握力和抓握疼痛的结构效度得到证实。PRTEE疼痛和无痛握力有反应。结论:所有测量结果均可靠。PRTEE的内容效度有问题。由于测量误差较大,对MIC的解释具有挑战性。

Measurement properties of core outcomes in patients with tennis elbow.

Background: The Patient-Rated Tennis Elbow Evaluation (PRTEE), pain on gripping, pain-free, and maximum grip strength are widely used outcomes for tennis elbow. This study tested the measurement properties with a prospective test-retest study design.

Methods: 100 participants with tennis elbow were included. The reliability, internal consistency, validity, responsiveness, and the Minimal Important Change (MIC) were evaluated.

Results: The reliability of all measures was acceptable. 8/15 PRTEE items were below the criteria for content validity. For PRTEE total score (0-100), the smallest detectable change 95% (SDC95%) was 17 points, and for the pain and function subscales (0-50) 8 and 12. For pain on gripping (0-10), the SDC95% was 4, and 6.4 kg for pain-free grip strength and 8.4 kg for maximum grip strength. The MIC for PRTEE total score was 9 points, 11 for pain and 4 for function. The MIC was 3.5 for pain on gripping, and 6.5 kg and 1 kg for pain-free and maximum grip strength. Construct validity was confirmed for PRTEE, pain-free grip strength, and pain on gripping. PRTEE pain and pain-free grip strength were responsive.

Conclusion: All measurements were reliable. PRTEE had questionable content validity. The interpretation of MIC is challenging due to large measurement errors.
