I also use your Prone Instability Test - it is a predictor variable for Hicks' Stabilization groups (Success and Some Improvement) in Treatment Based Classification.
You have a lot of good videos here - could you attach validity and reliability data to those where such data exist?
Thank you for your contribution.

@cervelo58 Thanks Tim. All the data (sensitivity, specificity, likelihood ratios, reliability coefficients, and in this case how it applies to the Core stabilization TBC) as well as hyperlinks to all the PUBMed abstracts appear for this test in the iPhone and Android version of this application.

In terms of reliability for this specific test:
Kappa (adjusted) = 0.58
Percent Agreement = 79%
Two examiners (chiropractors) with 10 and 25 years experience evaluated a total of 39 subjects with low back pain.
Schneider, J Manip Physiol Ther, 2008
Kappa = 0.52
Percent Agreement = 78.3%
Studying a total 123 patients with low back pain < 90 days (mean age = 38 years).
