title: Assessment of Consistency Between the Arm-Fossa Test and Gillet Test: A Pilot Study.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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."
  
  
  CONCLUSIONS
  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.
