McKenzie Method

Description/definition

The McKenzie method is a classification system and a classification-based treatment for patients with low back pain. A synonym for the McKenzie method is mechanical diagnosis and therapy (MTD). The McKenzie method was developed in 1981 by Robin McKenzie, a physical therapist from New Zealand. [1,4]
The McKenzie method exists of 3 steps: evaluation, treatment and prevention. The evaluation is received using repeated movements and sustained positions. With the aim to elicit a pattern of pain responses, called centralization, the symptoms of the lower limbs and lower back are classified into 3 subgroups: derangement syndrome, dysfunction syndrome and postural syndrome. The choice of exercises in the McKenzie method is based upon the direction (flexion, extension or lateral shift of the spine). The aims of the therapy are: reducing pain, centralization of symptoms (symptoms migrating into the middle line of the body) and the complete recovery of pain. The prevention step consists of educating and encouraging the patient to exercise regularly and self-care. [2,3,4]
All exercises for the lumbar spine are repeated a number of times to end-range on spinal symptoms in one direction. When you do only 1 repetition, this will cause pain. When you repeat it several times the pain will decrease. Also after movement termination the changes in pain intensity can persist, which leads to a treatment modality. A single direction of repeated movements or sustained postures leads to sequential and lasting abolition of all distal referred symptoms and subsequent abolition of any remaining spinal pain. [3]
