Pain response to sagittal end-range spinal motion. A prospective, randomized, multicentered trial.

This article reports a prospective, randomized, multicentered study documenting changes in the intensity and location of low-back and referred pain to repeated end-range lumbar flexion and extension movements performed first while standing and then while recumbent during a single clinical patient evaluation. Significant and rapid changes in central and distal pain intensity and location of peripheral pain resulted from the performance of these movements. For the mean in both protocols, regardless of the order of spinal movements, end-range extension significantly decreased central and distal pain intensity and centralized referred pain. Flexion spinal movements, however, significantly increased mean central and distal pain intensity and peripheralized the pain. Forty percent of individual subjects had a clear preference for extension and 7% a clear preference for flexion.

Centralization phenomenon. Its usefulness in evaluating and treating referred pain.

In patients with low-back and radiating leg pain, a clinical phenomenon has been described known as "centralization," which occurs during a mechanical evaluation protocol described by McKenzie. Relocation of the most distal pain in a proximal or central direction characterizes the pain behavior when patients are assessed in this fashion. Centralization typically occurs rapidly and can be maintained. In a review of 87 such patients, centralization occurred in 76 (87%). Its occurrence during initial mechanical evaluation is a very accurate predictor of successful treatment outcome and reliably determines the appropriate direction of treatment exercise. Nonoccurrence of centralization accurately predicts poor treatment outcome and was a helpful early predictor of the need for surgical treatment.

The McKenzie approach to evaluating and treating low back pain.

The McKenzie approach to evaluating and treating low back and neck pain is an exciting development in clinical medicine. A thorough mechanical assessment as described by McKenzie is informative and appropriate for all such patients and identifies an individualized self-treatment program that is often dramatically successful. Despite its world-wide use, this comprehensive discipline of evaluation and treatment is misunderstood or unappreciated by most medical practitioners. The assessment process and McKenzie's classification of low back pain syndromes--postural, dysfunctional, and derangement--are described. Therapeutic regimens emphasizing patient self-treatment for the current episode are presented, with the long-range goal of preventing recurrences.
