Overview of the McKenzie Method®

Abstract

The McKenzie Method® of Mechanical Diagnosis and Therapy® (MDT) is a system of classification and management based on clinical responses induced by specific mechanical loadings. This system can be applied to any musculoskeletal problem: e.g. low back pain, neck pain, and extremity symptoms. The MDT classification system comprises four major categories (Derangement Syndrome, Dysfunction Syndrome, Postural Syndrome, OTHER) and each category leads to a specific management strategy. This paper introduces: 1) the evaluation process leading to each category, 2) the criteria of the four categories and rate of each category, and 3) the significance of the MDT classification system. Some research findings are also presented to support its validity.
