2 thoughts on “The Prone Instability Test”
What are the sensitivity and specificity values on the anterior shear test?
I cannot find any research providing sensitivity and specificity. But, the prone instability test has the following …
Sensitivity: .72, Specificity: .58, +LR: .48, -LR: 1.7 (“Preliminary development of a clinical prediction rule for determining which patients with low back pain will respond to a stabilization exercise program”; it should be noted that the participants of the study had non-radicular low back pain).
From: Hicks G, Fritz J, Delitto A, McGill S. “Preliminary development of a clinical prediction rule for determining which patients with low back pain will respond to a stabilization exercise program.” Arch Phys Med Rehabil 2005; 86: 1753-1762.
Seeing both appear comparable in clinical practice, I would imagine it would be close to the above, but formal research would have to be performed.
