  Title Original research. Inter-examiner reliability of leg length inequality assessments
Journal Ann Vert Sublux Res. 2011 Summer;2011(3):Online access only p 51-56
Peer Review Yes
Publication Type Article

Introduction: Chiropractic leg length inequality (LLI) tests are used as a method of assessing, among other clinical aspects, the presence of some type of neurological disturbance thought to be related to vertebral subluxation. This study assesses inter-examiner reliability of four LLI procedures and hip extension procedure.

Methods: Two blinded examiners assessed the same 30 participants once for the five procedures. The kappa statistic was applied to determine the level of agreement. A kappa score of 0.40 or greater was considered as acceptable agreement.

Results: The prone hip/leg extension test exhibited a kappa score of 0.482 while the other LLI procedures showed kappa scores < 0.20.

Conclusion: In this study, only the prone hip/leg extension assessment revealed acceptable repeatability. Further research is warranted to verify these findings. Link to PDF version
