Unstable? Unreliable

Weekly nuggets of pain science news and insight, usually 100-300 words, with the occasional longer post. The blog is the “director’s commentary” on the core content of a library of major articles and books about common painful problems and popular treatments. See the blog archives or updates for the whole site.

You can’t very well treat core instability if you can’t diagnose it as a problem in the first place. This test of the reliability of core strength testing was a clear failure: “6 clinical core stability tests are not reliable when a 4-point visual scoring assessment is used.” Even if core strength is important (a separate question), this evidence clearly shows that no one should be claiming to be able to detect a problem with core weakness in the first place. A bit problematic for core dogma.

Just added this citation to my article about reliability studies—it's a really good example of poor reliability. Later I will add it to a half dozen more articles.
