Low back pain is the most common cause of disability in the working population. Approximately 50-80% of the adult population will experience LBP at some point in their life. The pain location could be localized to the back, unilateral (one side only), bilateral (both sides) or radiate into the lower extremity. Some may or may not also experience the presence of paraesthesia (pins and needles sensation).
There is a strong evidence to support the role of : education, behavioural therapy, manipulation, and exercise. However, there is little evidence to support the use of passive therapy, including but not limited to the use of modalities, electrical stimulation and bed rest.
Less than 15% of low back pain can be given a specific diagnosis. Thus, Mechanical Diagnosis and Therapy (McKenzie) system of assessment and treatment uses non-specific classification. One such classification within the system is the Lumbar derangement pertaining to LBP.
Derangement syndrome is a clinical presentation seen in a mechanically obstructed affected joint. The key feature of this clinical presentation is directional preference and centralization (if present). A common analogy I have heard many clinician use is- like a door hinge, you know it is supposed to go either way but sometimes for whatever reason it may be jerky to move in one direction or very rigid to move. Thus, we may lubricate it with oil and keep moving it in the obstructed direction of movement until it frees up.
*Centralization is a phenomenon seen in the derangement syndrome and is a good prognostic indicator. Centralization means that the pain originating from the spine progressively disappears from the distal to proximal direction. In other words, pain that was in your foot and calf (distal) and upper thigh gradually goes away until you are left with pain in your lower back (central).
There are sub types within the lumbar derangement. However, in the following example we will be discussing the most common type which is Posterior derangement.
These are derangements which have a preference to extension exercises (bending backwards).
These can be seen in people who are more prone to favouring forward bending movements, such as the physical demands of being a nurse or working/sitting at a desk.
When we flex forward (bending forward), using the disc model as an example, there is posterior displacement of disc material and the intra-discal pressure increases up to 80%.
Patients may have difficulty with: straightening themselves up, sitting for too long, rising from a seated position, etc. They may feel better with lying on their tummy, walking, and when they are on the move.

This patient came in with a painful and disturbing clunking sensation while reaching overhead. With his consistency you can see his progress through his injury rehabilitation.
Many people don’t realize that they can come in BEFORE they have pain. You don’t have to wait until the pain effects your quality of life to come to physio.
