The purpose of this pilot study was to test methods needed to conduct a study with adequate power to investigate consistency between the arm-fossa test (AFT) and the Gillet test.
A convenience sample of chiropractic college students enrolled in a weekend Sacro-Occipital Technique seminar participated. Each was tested with AFT and sacroiliac orthopedic tests, including the Gillet test. Statistical testing included calculation of κ for consistency of the AFT and Gillet test and their diagnostic efficiency.
This study recruited 14 participants. Important issues arose in gathering and recording data, the standardization of examiner methods, and the flow of participants to examination stations. κ for AFT and Gillet test consistency = 0.55, corresponding to "moderate."
This pilot suggests that the future study should include a mix of symptomatic and asymptomatic participants; record trichotomous data, where appropriate; use washout periods between diagnostic tests; and refine the selection of orthopedic tests deployed besides the AFT. The preliminary data are consistent with but do not establish due to the very small sample size and experimental design issues, that a positive AFT may be consistent with a negative Gillet test.
本初步研究的目的是测试进行一项有足够效能的研究所需的方法,以调查臂窝试验(AFT)和吉列试验之间的一致性。
选取参加周末枕下技术研讨会的整脊学院学生作为便利样本。每位学生都接受了AFT和骶髂关节骨科检查,包括吉列试验。统计测试包括计算AFT和吉列试验一致性的κ值及其诊断效率。
本研究招募了14名参与者。在数据收集和记录、检查者方法的标准化以及参与者到检查站点的流程方面出现了重要问题。AFT和吉列试验一致性的κ值 = 0.55,对应于“中等”。
本初步研究表明,未来的研究应纳入有症状和无症状参与者;在适当情况下记录三分法数据;在诊断测试之间使用洗脱期;并完善除AFT外所采用的骨科检查的选择。由于样本量非常小和实验设计问题,初步数据虽与之相符,但尚未证实阳性AFT可能与阴性吉列试验一致。
