The McKenzie method (also MDT = Mechanical Diagnosis and Therapy) is a comprehensive method of care primarily used in physical therapy.

New Zealand physical therapist Robin McKenzie, OBE (1931-2013) developed the method in the late 1950s. In 1981 he launched the concept which he called Mechanical Diagnosis and Therapy (MDT) - a system encompassing assessment (evaluation), diagnosis and treatment for the spine and extremities. MDT categorises patients' complaints not on an anatomical basis, but subgroups them by the clinical presentation of patients.

Terminology

The McKenzie method consists of two components used to treat musculosceletal conditions: assessment and intervention. The assessment component of the McKenzie method uses repeated movements and/or sustained postures in a single direction to elicit centralisation. In spinal patients centralisation refers to a pattern of pain level response which is characterised by decreased or abolished pain symptoms, experienced sequentially, first to the left and right of the spine (distal symptoms), and ultimately abolished pain symptoms in the spine altogether.

The assessment portion attempts to discover "directional preference", which identifies the pattern of lumbosacral movement in a single direction that effectively results in centralisation and subsequent abolishment of pain symptoms in the spine and the return of proper range of motion.

The intervention component of the McKenzie method is the corresponding repeated and/or sustained flexion and extension movements as prescribed by the assessment component.

History

''Everything I know I learnt from my patients. I did not set out to develop a McKenzie method. It evolved spontaneously over time as a result of clinical observation'' - Doctor Robin McKenzie.

The McKenzie method has its roots in a single event in 1956 that led to increased experimentation of certain movement in order to elicit what is now known as the centralisation phenomenon. A patient who was experiencing pain on the right side of his lower back buttock, laid down on doctor McKenzie's treatment table. The patient ended up lying in significant lumbar extension for around five minutes, meaning his back was bending backwards because the head of the table had been raised for a previous patient. After ceasing this sustained position in lumbar extension the patient noted the pain on the right side of his body had experienced surprising and significant improvement.

This led McKenzie to continuously experiment with specific movement and movement patterns to treat chronic lower back pain and bring about centralisation of pain symptoms. Over the years of experimentation in Robin McKenzie's career, he noted patterns of symptom relief in response to prescribed spinal movements and positions and developed a classification system to categorise spinal pain problems. McKenzie went on to write and publish books so people could manage and treat their own back pain, such as "Treat Your Own Back" first published in 1980, with the latest edition being published in 2011.

Description

The McKenzie Method also referred to as Mechanical Diagnosis and Therapy is a method of assessing and treating spinal back pain and related extremity pain most commonly through the use of specific repeated movements and appropriate prevention measures. The method puts an emphasis on self-care after initial clinical visits. There are four major steps when it comes to proper McKenzie method therapy: assessment, classification, treatment, and prevention.

The assessment or evaluation procedure determines the type of movements that result in centralisation and reduction in pain.

MDT uses primarily self treatment strategies, and minimises manual therapy procedures, with the McKenzie trained therapist supporting the patient with passive procedures only if an individual self treatment program is not fully effective.

McKenzie states that self treatment is the best way to achieve a lasting improvement of back pain and neck pain.

Centralisation

Centralisation plays an enormous role to treating patients with lower back pain with the McKenzie method.

Centralisation occurs when Pain symptoms off-centred from the mid-line of the spine, often diagnosed as sciatica, migrate towards the centre of the mid-line of the spine. This migration of pain symptoms to the centre of the lower back is a sign of progress in the McKenzie method. A patient has found their directional preference once they discover which repeated end-range exercise movements elicit centralisation of pain symptoms. The most common directional preference that result in centralisation is extension of the back. In many cases extension exercises are commonly referred to as McKenzie exercises for this very reason.

According to the McKenzie method, movements and exercises that produce centralisation are very beneficial whereas movements that create pain that wander from the spinal mid-line are extremely detrimental to a patients specific condition. A 2012 systematic review found that lumbar centralisation was associated with a better recovery prognosis in terms of pain, short- and long-term disability, and the likelihood of undergoing surgery in the following year

Assessment

The first step is understanding a patients symptoms and how they behave. Such as where patient feels pain and when, how often in a day, to what degree, and in what specific movements or positions does pain intensify or express itself. The patient will be tested and asked by a clinician to perform specific single direction movement, both sustained and repeated. A large differentiator from other physical therapy methods of assessment is the use of repeated movements. A range of single direction movements are used in this phase of the McKenzie method, depending on how pain symptoms behave and change will allow the clinician to categorise the problem to effectively prescribe the proper movements to achieve centralisation and elimination of spinal and sciatic pain.

Classification

There are three primary classifications that result from the assessment portion of the McKenzie method's comprehensive approach; Postural syndrome, dysfunction syndrome, and derangements syndrome with a minority of patients falling into an 'other category. Each classification represents the likely underlying reason of experienced pain symptoms and symptom behaviour. The classification process is very important because it determines if the McKenzie method is an appropriate approach for specific patients and also determines which movement and protocols will most likely lead to centralisation and a cessation or reduction of pain symptoms. Each syndrome corresponds to specific mechanical procedures.

Treatment

Depending on the classification and the nature of the underlying cause of disablement, certain treatment protocols are used. Depending on classification type and directional preference, patients perform specific exercises to end-range. There will be limited mobility and the position will likely cause discomfort, but the patient repeats the exercises one after the other until centralisation occurs, pain symptoms subside, and mobility to end-range increases.

Derangement Syndrome

The most common treatment classification. Defined by pain that is experienced due to a disturbance in the joint area resulting in diminished movement in certain directions. Depending on a patients specific directional preference as discovered in the assessment stage of the McKenzie method, patients are prescribed to use repeated movements in a single direction that cause a gradual reduction in pain and centralisation of pain symptoms. That is, symptoms of pain from the left and right of the middle-lower back become centralised to the centre of the lower back and over time result in lasting reduction of pain symptom intensity.

Dysfunction Syndrome

This type of pain is categorised by mechanical impairments and deformities of impaired tissue within the body such as scar tissue or shortened tissues. To treat this treatment classification the goal is to remodel the impaired tissue by mobilisation exercise

Postural Syndrome

This type of pain is the result of postural deformation. Static holds of improper end-range positions, such as slouching are the cause of postural syndrome. Treatment is more geared towards education and proper posture training rather than repeated exercises as the other syndrome classifications prescribe.

Prevention

The last portion of treatment is designed to educate patients to ensure proper continuation of appropriate exercises and correct structural positionings day-to-day. Self-care and proper exercise is stressed and encouraged as prevention methods.

Medical Literature Concerning Efficacy of Treatment

According to a meta-analysis of clinical trials in 2006, treatment using the McKenzie method is somewhat effective for acute low back pain, but the evidence suggests that it is not effective for chronic low-back pain. A 2012 systematic review agreed with this, finding that centralisation occurred more frequently in acute patients (74%) compared to subacute (50%) and chronic (40%). Also, centralisation was found to be more common in younger patients. Cervical centralisation was observed in only 37% of patients.

There have also been other reviews of the literature.

A 2006 systematic review into the clinical evidence of the McKenzie method's ability to treat spinal pain concluded that the McKenzie method decreased short-term (<3 months) to a higher degree than other standard treatments including: "nonsteroidal anti-inflammatory drugs, educational booklet, back massage with back care advice, strength training with therapist supervision, and spinal mobilization". At the intermediate term follow-up there was no statistical differences among therapies.

A report published in 2008 noted only marginal benefits over an assessment and advice-only group at the short-term follow up mark, 6 month, and 1 year.

A 2010 study concluded that the McKenzie method "does not produce appreciable additional short-term improvements in pain, disability, function or global perceived effect".

A 2006 systematic review of the literature assessed whether or not the McKenzie method treated Lower back pain more effectively than passive therapy, advice to stay active, flexion exercises, and others. The assessment concluded that there were no clinically significant benefits compared with the passive therapy and advice to stay active in those with acute lower back pain
