The McKenzie Method for Back and Neck Pain

The McKenzie method, also known as MDT (Mechanical Diagnosis and Therapy), is a systematic way of assessing and treating back and neck problems. Rather than relying on imaging alone, it uses repeated movements and positions to find out exactly what makes the problem better or worse – and uses that actively in treatment.

Why use movement as a tool?

Many back and neck problems, including those with symptoms radiating into the arm or leg (as with sciatica or a disc herniation), respond predictably to certain movements and positions. By testing systematically – for example, repeated bending backward or forward – it's often possible to identify a pattern: the pain may move closer to the spine and disappear from the arm or leg, or it may worsen and spread further out.

This phenomenon is called centralisation, and is one of the most important findings in a McKenzie assessment. It provides valuable information about prognosis, and – importantly – which direction of movement should be used in treatment.

Three main categories

After the assessment, the problem is usually classified into one of three categories, each with its own approach:

• Derangement – the most common category, often related to the disc between the vertebrae. Symptoms change clearly with movement, and respond well to a specific exercise direction.
• Dysfunction – stiffness in tissue following a previous injury or prolonged strain, where discomfort occurs at the end range of a movement.
• Postural – pain caused solely by prolonged static loading, such as sitting still, which disappears once the position changes.

You learn to treat yourself

What sets the McKenzie method apart from many other approaches is the emphasis on self-treatment. Once we've found the movement or position that provides relief, you're given a specific exercise programme to do yourself, often several times a day for a period. The goal is for you to be able to quickly influence your own symptoms and regain normal movement and function, without depending on treatment for every flare-up.

Manual treatment in the clinic can still be useful as a supplement, especially early on or for stiffness that's difficult to move on your own.

Who is this method suitable for?

The McKenzie method is well suited for most mechanical back and neck problems, including disc-related symptoms. The assessment itself is also diagnostically useful – if symptoms don't follow an expected mechanical pattern, that's a signal the problem should be investigated further in another way, such as with imaging or a medical assessment.
