McKenzie assessment also helps you rule out those that are out of the 3 syndromes. The various diagnosis that feature in the other category, for example - red flags, yellow flags, central canal stenosis, lateral foraminal stenosis, symptomatic spondy, mechanically inconclusive etc. It is now an all known fact that radiology andMRI findings are not all conclusive. Hence I would say, an X-ray of a patient may show degenerative changes, but is the patient manifesting with the pain because of it ?
Mckenzie system also teaches you how to restore the patient back to their functions.
