Level of evidence: A case control study.

Objective: The purpose of this study is to determine the intra-rater reliability of the Clavicular Jump Test (CJT).

Design: This is a case control one-group pretest-posttest (repeated measures) study.

Methods: 96 participants with an average age of 28 (± 4. 78) volunteered to participate in this research project. A single examiner, blinded to the identity of the participants, conducted the CJT on both shoulders, then repeated the test on each participant in a random order.

Results: The results of a pearson chi-square test of the CJT of trial 1 and trial 2 on the right side indicated a statistically significant agreement, χ² (1)=44. 29, p<0. 05 with kappa statistic (k) of the CJT of trial 1 and trial 2 on the right side indicating “substantial levels” of agreement, k=0. 67, p<0. 05. The results of a pearson chi-square test of the CJT of trial 1 and trial 2 on the left side indicated a statistically significant agreement, χ² (1)=5. 69, p<0. 05 with kappa statistic (k) of the CJT of Trial 1 and Trial 2 on the Left side indicating “fair” levels of agreement, k=0. 24, p<0. 05. A post-hoc power analysis showed to have a power (1-β)=0. 84.

Conclusion: There is now intra-rater reliability for the CJT. There is methodology created during this study that makes assessing the reliability of the CJT in a practice environment possible.
