Abstract

Background: Shoulder pain is the third most common musculoskeletal complaint in today’s society. Approximately 50% of patients with shoulder pain seek medical attention, which includes physical therapy. A thorough understanding of the anatomy of the shoulder, including its fascial attachments, its biomechanics, and functional relationship to nearby spinal regions is crucial for successful rehabilitation diagnostics and treatment interventions. Purpose: The purpose of this study is to determine the intra-rater reliability of the Clavicular Jump Test (CJT). Methods: This study is a quasi-experimental, one-group pretest-posttest (repeated measures), and correlation design. A total of 96 subjects (47 males and 49 females) volunteered to participate in this research project. The average age for the subjects was 28 (± 4.78) and ranged from 18 to 49 years old. Results: The results of a Pearson Chi-square test of the Clavicular Jump Test of Trial 1 and Trial 2 on the Right side indicate a statistically significant agreement, χ2 (1) = 44.293, p < 0.05. The calculated kappa statistic (k) of the Clavicular Jump Test of Trial 1 and Trial 2 on the Right side indicate “substantial levels” of agreement, k = .672, p < .05. The results of a Pearson Chi-square test of the Clavicular Jump Test of Trial 1 and Trial 2 on the Left side indicate a statistically significant agreement, χ2 (1) = 5.696, p < 0.05. The calculated kappa statistic (k) of the Clavicular Jump Test of Trial 1 and Trial 2 on the Left side indicate “fair” levels of agreement, k = .241, p < .05. A post-hoc power analysis was conducted and showed to have a power (1-β) = 0.84 for the Chi-square testing. Conclusion: There is now intra-rater reliability for the Clavicular Jump test. There is methodology created during this study that makes assessing the reliability of the Clavicular Jump Test in a practice environment possible. Based on this methodology it is possible to test and educate clinicians for using the Clavicular Jump Test.
