By far the most common form of ⚡ dysfunction ⚡ is that involving loss of extension. Having already explained and taught the postural requirements, we must now instruct the patient in the methods required to regain lost extension. We must explain to him the reasons for the need to recover the extension movement. The patient must realise that without an adequate range of extension it is not possible to sit with a lordosis, even when a lumbar support is used. For some patients it is imperative that the range of extension be improved, otherwise they will be unable to sit correctly. It is my experience that, following adequate explanation, patients will co-operate with the treatment and work hard at their recovery. They will perform exercises that cause discomfort or even pain, as long as they understand the reasons for doing so.


Fig. Recovery of loss of extension, using the procedure of extension in lying.


In order to systematically stretch the lumbar spine in extension, I have adopted a system in which the patient is able to use gravity and his own body weight to apply enough force for adequate passive stretching of the joints of the lumbar spine. This procedure, a modified press-up exercise, is extension in lying. If with this exercise the desired result is not obtained quickly enough or if progress ceases, extension in lying with belt fixation must be commenced.

If due to circumstances it is absolutely impossible to perform extension exercises in lying, extension in standing must be performed instead. But it must be emphasised that a far better extension stretch is obtained with extension exercises in lying.


The patient should be instructed to perform the exercise ten times on each occasion, and to repeat the series ten times a day at intervals of approximately two hours. It is most important to ensure that stretching occurs very regularly and the patient does not let more than two to three hours pass by without doing so.

The exercise routine should result in an increase of localised central back pain which subsides within ten to twenty minutes. The patient should also develop some new pains higher up in the spine and across the shoulders. These are normally the result of performing new exercises and holding a new posture. It is necessary to explain that the combination of the new posture and exercises will result in discomfort felt in other places; that this new aching is unavoidable and indeed necessary, but will pass after a week or so. Patients who do not complain of these transitional pains are probably not exercising adequately.

Irrespective of the category in which they may fall, all patients should be warned of the significance of producing peripheral pain. If exercises are found to produce peripheral pain, the patient should stop and wait until the next treatment when further advice should be sought.

The loss of function in patients in this group is usually resolved gradually over a period of about four to six weeks. After this period the patient may reduce the number of times the exercises are performed to four sessions per day, maintaining the number of ten repetitions at each session. I instruct my extension dysfunction patients that they should continue the programme and perform ten exercises twice daily for the rest of their lives.


Often it is desirable to keep some record of progress and the therapist may choose to take photographs to evaluate the improvement in the lumbar extension curve. The improvement is most evident in the first week, and therefore the first photographs should be taken on the first day prior to the commencement of the self-treatment programme.

Special techniques

As soon as progress slows down or ceases it is time to add mobilisation techniques. If after three to four mobilisation treatments no change is evident, the patient should be manipulated. Special techniques of mobilisation and manipulation are indicated, when the patient is unable to fully restore lumbar extension himself. These procedures may ensure full recovery of extension provided the extension exercises in lying are continued as well.

Kyphosis: Causes, Symptoms and Diagnosis What Causes Kyphosis? Kyphosis, also known as roundback or hunchback, is a condition in which the spine in the upper back has an excessive curvature. The upper back, or thoracic region of the spine, is supposed to have a slight natural curve. The spine naturally curves in the neck, upper back, and lower back to help absorb shock and support the weight of the head. Kyphosis occurs when this natural arch is larger than normal. If you have kyphosis, you may have a visible hump on your upper back. From the side, your upper back may be noticeably rounded or protruding. In addition, people with hunchback appear to be slouching and have noticeable rounding of the shoulders. Kyphosis can lead to excess pressure on the spine, causing pain. It may also cause breathing difficulties due to pressure put on the lungs. Kyphosis in elderly women is known as dowager’s hump. Common causes of kyphosis Kyphosis can affect people of any age. It rarely occurs in newborns because it’s usually caused...
Back pain. Predisposing and Precipitating Factors PREDISPOSING FACTORS Sitting posture There are three predisposing factors in the etiology of low back pain that overshadow most others. The first and most important factor is the sitting posture. A good sitting posture maintains the spinal curves normally present in the erect standing position. Postures which reduce or accentuate the normal curves enough to place the ligamentous structures under full stretch will eventually be productive of pain. Such postures are referred to as poor sitting postures. A poor sitting posture may produce back pain in itself without any additional other strains of living. We have all seen patients who entered an airliner, a car, or even a common lounge chair in a perfectly healthy and painfree state only to emerge hours later crippled with pain and unable to walk upright. Alternatively, a poor sitting posture will frequently enhance and always perpetuate the problems in patients suffering from low back pain. By far the great majority of patients comp...
Spine Health. PROCEDURE 17 – SELF-CORRECTION OF LATERAL SHIFT Having corrected the lateral shift and the blockage to extension, it is now essential to teach the patient to perform self-correction by side gliding in standing followed by extension in standing. This must be done on the very first day, so that the patient is equipped with a means of reducing the derangement himself at first sign of regression. Failure to teach self-correction will lead to recurrence within hours, ruining the initial reduction, and the patient will return the next day with the same deformity as on his first visit. I have discarded the technique of self-correction as described previously and instead I now teach patients to respond to pressures applied laterally against shoulder and pelvis. Initially, therapist’ assistance is required. Patient and therapist stand facing each other. The therapist places one hand on the patient’s shoulder on the side to which he deviates, and the other hand on the patient’s opposite iliac crest. The therapist applies pressure by squeez...
The Intervertebral Disc STRUCTURE In the lumbar spine the intervertebral discs are constructed similarly to those in other parts of the vertebral column. The disc has two distinct components: the annulus fibrosus forming the retaining wall for the nucleus pulposus. The annulus fibrosus is constructed of concentric layers of collagen fibres. Each layer lies at an angle to its neighbour and the whole forms a laminated band which holds the two adjacent vertebrae together and retains the nuclear gel. The annulus is attached firmly to the vertebral end plates above and below, except posteriorly where the peripheral attachment of the annulus is not so firm. Moreover, the posterior longitudinal ligament with which the posterior annulus blends is a relatively weak structure, whereas anteriorly the annulus blends intimately with the powerful anterior longitudinal ligament. The posterior part of the annulus is the weakest part: the anterior and lateral portions are approximately twice as thick as the posterior port...
TREATMENT OF FLEXION DYSFUNCTION Loss of flexion is the second most common movement loss in the lumbar spine. It manifests itself in several ways, which interfere with either the amount of available flexion or the pathway taken to achieve flexion. This type of dysfunction is commonly seen in patients with an accentuated lordosis. Patients with significant flexion dysfunction are usually unable to sit slouched with a convex lumbar spine. When giving postural instructions to these patients, we must explain that once sitting relaxed they place the lumbar spine on full stretch much sooner than patients with a normal flexion excursion. Fig. Recovery of loss offlexion, using the procedure of flexion in standing. Recovery of pure flexion loss To regain flexion we must, just as in the case of extension dysfunction, explain to the patient the purpose of performing exercises. Again, we must stress the necessity of causing a moderate degree of discomfort or pain with the exercises. Pain produced by stretching of contra...
