Abnormal morphology

The thoracic spine is prone to the usual range of degenerative and maturation changes that affect other areas of the spine, plus some that principally affect this region. With age the thoracic kyphosis tends to increase, a process that is accentuated by reduced physical activity, postural habit and female gender (Singer 2004). A number of specific pathologies, some asymptomatic, can exacerbate this these include ankylosing spondylitis, Scheuermann's disease, diffuse idiopathic skeletal...

About the Authors

Robin McKenzie was born in Auckland, New Zealand, in 1931 and graduated from the New Zealand School of Physiotherapy in 1952. He commenced private practice in Wellington, New Zealand in 1953, specialising in the diagnosis and treatment of spinal disorders. During the 1960s, Robin McKenzie developed new concepts ofdiagnosis and treatment derived from a systematic analysis of patients with both acute and chronic back problems. This system is now practised globally by specialists in physiotherapy,...

Ageing and degeneration

Certain changes occur within the cervical motion segment and are deemed to be 'normal' some of these changes occur relatively early in life (Taylor and Twomey 2002 Oliver and Middleditch 1991 Bland 1998). Changes in childhood include the development of uncinate processes on the vertebral bodies and the formation of uncovertebral clefts from the uncinate processes. These clefts spread medially across the posterior disc during adolescence and early adulthood and commonly produce horizontal...

Alternative positions for Procedure 2 Retraction and extension

Retraction and extension with rotation in supine The patient should be instructed to lie supine over the end of the treatment table so that the head, neck and shoulders are unsupported down to the level of the third or fourth thoracic vertebra. The patient places one hand under the occiput to provide assurance and stability (Photo 44). The patient then fully retracts the head (Photo 45) and is instructed to continue the movement by slowly and steadily tilting the head backwards as far as...

Alternative positions Procedure 5 Rotation

Patient lies supine on the treatment table. The head may be supported on a pillow if necessary. Placing a piece of shiny paper under the occiput allows a better rotation movement to be performed. The patient turns the head, generally towards the side ofthe pain (Photo 73). The position is maintained for one or two seconds, and then the head is returned to the neutral position. The movement is repeated about ten times. Rotation in supine with patient overpressure Ifa progression of force is...

Ankylosing spondylitis

Ankylosing spondylitis is an inflammatory systemic disease that can affect the whole spine. It usually commences with sacral and lumbar pain, but may involve the thoracolumbar spine early on (Singer 2000). Once the thoracic spine is involved, due to involvement of the costal joints, respiration may become impaired. Later on the disease causes ankylosis of joints and ossification of ligaments leading to an immobile, fused spine and structural deformity, such as a fixed thoracic kyphosis....

Clinical picture

Patients with solely postural pain are usually under 30 years old, often much younger - schoolchildren may be brought to the clinic by concerned parents. Individuals are generally sedentary due to their occupation, studies or lifestyle. They usually have spinal pain only, without referral, but may describe pain in the thoracic and lumbar regions as well. Frequently they have been getting symptoms for months, which have been getting gradually worse - pain is now coming on more quickly and...

Conclusions

This chapter has described the classification system used in the thoracic spine. The first duty of the clinician is to detect patients who have serious spinal pathology A series of 'red flags' might indicate the presence of serious pathologies, and any such patients should be referred for further investigation - these are detailed in Chapter 8. It should be remembered also that thoracic pain may result from visceral disorders, although ascribing visceral disease to thoracic musculoskeletal...

Differential diagnosis

The prevalence figures suggest that the differentiation between the different headache types is straightforward, uncontroversial and simple to make, but this is not the case. One problem is the use of different diagnostic criteria. For instance, Haldemann and Dagenais (2001) list five different criteria for cervicogenic headache, which have certain consistent features, but each includes distinctive characteristics. The most extensive classification criteria produced by IHS has been criticised...

Distinguishing chemical and mechanical pain

As the cause of pain is an important determinant of the appropriateness of mechanical therapy, it is vital to distinguish between mechanical and chemical sources ofnociception (McKenzie 1981, 1990). We can begin to distinguish between these types of pain by certain factors gained during the history-taking and largely confirm this impression during the physical examination. A key characteristic that indicates the possibility of pain of chemical origin is constant pain. Not all constant pain is...

Health careseeking

As with those who have lumbar back pain, not everyone with neck pain seeks health care. In the Netherlands, just over 50 of those with neck-shoulder-upper back pain had contact with a Gp, specialist or physiotherapist (Picavet and Schouten 2003). In the US, in two studies with a mixed population of neck and or back pain, 25 to 66 had sought health care from a complementary or conventional provider (Cote et al. 2001 Wolsko et al. 2003). In the UK, 69 consulted a health professional, mostly their...

History

As mentioned in the introduction, most items of history-taking are the same as those used for neck pain patients, and much of the detail in the chapter on cervical history is relevant here. However, some items that are relevant specifically to the thoracic spine need further comment. In the thoracic spine the patient's age may alert one to the possibility of Scheuermann's disease, which affects adolescents, whilst osteoporosis is a consideration in older patients, especially older women. These...

Horners syndrome

Horner's syndrome occurs as a result of interference to the sympathetic nerve supply to the eye in the central or peripheral nervous system (Berkow et al. 1992 Walton and Buono 2003). It comprises the following symptoms variable drooping of upper eyelid - ptosis constriction of the pupil - miosis ipsilateral loss of sweating - anhydrosis recession of eyeball into the socket - enopthalmos. This may result from central nervous system lesions or damage to the cervical sympathetic chain or...

Introduction

Headache is a commonly reported symptom with a variety of causes, both serious and benign. Some headaches arise secondary to a neck problem with the primary complaint in the neck - such patients should be classified with one of the mechanical syndromes and managed in the same way as described elsewhere in the book. Some patients attend primarily with the complaint of headache, although there may be some secondary neckache - this chapter addresses this group. Headache means pain anywhere in the...

Management lateral component with lateral deviation wry neck or acute torticollis

These patients, few in number, are identified by the obvious lateral deviation of their head and neck. The patient is fixed in flexion, lateral flexion or rotation, or a combination of these. The patient cannot laterally flex, rotate or extend normally. The pain and deformity is usually of very recent onset. The patient may in some cases be able to bring their head back to mid-line, but is unable to maintain this correction. This deformity is termed a contralateral shift if away from the...

These symptoms may be pain anc Jor paraesthesia and may be accompanied by pain in the arm, shoulder, scapular region or neck. These patients are those previously classified as Derangements 5 and 6, and comprise up to 20 of the neck pain population (McKenzie 1990). Specific cervical pain with clear aetiology is more likely in this group as...

Mechanical diagnosis and therapy and clinical reasoning

Clearly elements of the classical description of clinical reasoning are as relevant to the McKenzie Method as any other. Data-gathering, knowledge base, clinical experience and thought processes during the clinical interaction are all central to mechanical diagnosis and therapy. However, there are limitations and problems with the process of clinical reasoning as described. The list ofwhat knowledge base is needed is considered incomplete, as knowledge from other areas can be required also...

Mechanical nociception

Pain may be produced in the absence of actual tissue damage by excessive mechanical strain or tension upon collagen fibres. This is thought to be the result of the deformation of collagen networks so that nerve endings are squeezed between the collagen fibres, with the excessive pressure perceived as pain (Bogduk 1993). No damage to the tissues need have occurred, and when the stress is removed the pain abates. Me weakened, damaged or abnormal tissues. If the excessive strain is so great as to...

Mechanically determined directional preference

Mechanically determined directional preference describes the situation when postures or movements in one direction centralise, abolish or decrease symptoms and lead to an improvement in mechanical presentation. Very often postures or movements in the opposite direction cause symptoms and signs to worsen, although in part this is a response to the length of exposure to the provocative loading. The phenomenon of mechanically determined directional preference is characteristic of derangement...

Natural history

A number of studies suggest that, like lumbar back pain, the natural history of neck pain is frequently protracted and episodic. In two long-term follow-ups of over 250 patients with neck pain, nearly 60 reported on-going or recurrent problems (Lees and Turner 1963 Gore et al. 1987). In those who had on-going symptoms, just over half reported them to be moderate or severe (Gore et al. 1987). Retrospectively, 42 of a general population sample of nearly four thousand reported an episodic history...

Onset

Commonly, a sudden or insidious onset of neck pain is reported (McKenzie 1981 Kramer 1990), This would suggest that normal daily mechanical loading might frequently trigger neck pain symptoms, Kramer (1990) reports that symptoms are brought on by prolonged kyphotic posture during reading or deskwork, by rotational movements, or, so patients report, from sitting in a draft Equally sustained loading during sleep may trigger symptoms, In a random population-based study, about 20 reported commonly...

Postural syndrome

The postural syndrome is characterised by intermittent pain brought on only by prolonged static loading of normal tissues. Time is an essential causative component, with pain only occurring following prolonged loading. However, the loading period required to induce symptoms may decrease with repeated exposure over time. Patients with the postural syndrome experience no pain with movement or activity. Neither do they suffer restriction of movement. No pathological changes occur in this syndrome....

Postural syndrome aggravating factor standing

Patients rarely report cervical postural pain that occurs in standing, presumably as this position allows greater postural variety and they escape sustained end-range postures. Occasionally someone who works standing in a position of sustained neck flexion or protruded head posture may present. For management, the same principles apply. If sustaining the causative posture can reproduce symptoms, the effects of resuming a more neutral posture are quickly established. If symptoms cannot be...

Preventative strategies

It is reasonable to advise patients about aspects of the epidemiology of neck pain. Not everyone with neck pain has future episodes, but a considerable proportion have future or persistent episodes. Warnings regarding the natural history of neck pain, which is commonly episodic or persistent, thus represent a responsible aspect of management. Most patients are interested in prognosis and clinicians are responsible for providing this information. Two main aspects should be discussed what can be...

Procedure 2 Retraction and extension

Can be performed in sitting, supine or prone. Retraction and extension in sitting Head and neck retraction and extension are the movements of retraction, followed immediately by movement of the head and neck into the fully extended position. Although there are two movements involved, they should appear to blend smoothly into one continuous motion until finally the neck is fully extended. This procedure can be commenced once the patient is proficient in performingbasic retraction and a good...

Severity and disability

The last study also reported on symptom severity. In those with continuous or recurrent pain (84 ), 11 reported this to be severe, but a further 10 reported severe episodes against a background of mild continuous pain (Picavet and Schouten 2003). A minority (6 ) reported partial disability from work and work leave greater than four weeks due to neck symptoms however, while 29 reported some limitation of daily living, the majority (80 ) reported no or minimal work loss (Picavet and Schouten...

Thoracic pain

As mentioned above, there is ample room for confusion between symptoms that emanate from the thoracic and cervical spines. Several studies have indicated that pain around the scapular and shoulder region commonly arise from cervical discogenic or zygapophyseal joint disorders (Cloward 1959 Smith 1959 Whitecloud and Seago 1987 Grubb and Kelly 2000 Dwyer et al. 1990 Aprill et a .1990). However, stimulation of thoracic structures has also caused pain in the chest and scapular region (Bogduk...

Upper cervical instability

A generally accepted definition of instability does not exist (Swinkels and Oostendorp 1996). Concerns about instability at upper cervical levels relate to systemic conditions, such as rheumatoid arthritis (RA) or cervical trauma (Aspinall 1990 Bland 1994). There may be a discrepancy between the degree of destruction or instability and the symptoms. Patients with slight instability may have major neurological problems, whereas others may have significant laxity without neurological symptoms...

Epidemiology of headache

Headaches are extremely common in the general population and a very common reason for seeking health care. The literature on the prevalence of headache in forty-four studies was summarised in 1999 (Scher et al. 1999). At age 40 there was an estimated prevalence in males of 25 in Europe and just over 60 in North America, and in females of 70 - 80 in both these areas (Scher et al. 1999). It is unclear why there is such a marked difference between European and North American males. Lifetime...

Surgery for cervical and thoracic problems

Indications for cervical surgery are said to be instability, often secondary to rheumatoid arthritis or trauma, radiculopathy, myelopathy and tumour Qones 1998). In the thoracic spine, thoracic disc herniations causing progressive myelopathy, trauma that may cause spinal cord lesions, and progressive deformity that fails to respond to conservative measures are said to be indications for surgery (Findlay and Eisenstein 2000). If treatment is considered for thoracic scoliosis deformity, this may...

Management of dysfunction syndrome

The treatment of adhesions, contractures or adaptive shortening as in an articular dysfunction essentially requires the application of movements that encourage the process of remodelling. Only with the application of such loading strategies will normal tissue function be re-established. Ideally such movements commence during the stages of repair and remodelling in the weeks after an injury (Evans 1980 Hardy 1989 Hunter 1994 Barlow and Willoughby 1992). If appropriate and graded tension is...

Instructions to all patients with dysfunction syndrome

Patients will be attending the clinic with pain. To be told that they must go away and regularly cause the pain that they are complaining about needs a very good explanation to gain their adherence to the programme. As long as patients are given a good justification for performing the exercises, most will follow the advice that is given. Most will understand the idea of scar tissue that needs to be 'stretched' to recover full movement that stretching the scar hurts, and on releasing the stretch...

Classification of WAD

As the identification of specific pathology without the use of intrusive injection technology is highly problematical, classification is usually based on symptomatology. Most commonly this is related to duration of symptoms, which are described as either acute or chronic. The Quebec Task Force (QTF) classification attempts to portray some level of the severity of symptoms resulting from a whiplash injury (Spitzer et al. 1995) . Neck pain, stiffness or tenderness only Mechanical signs reduced...

Treatment pathways in derangement

Description of the management of derangement is based on two considerations. The numbering system is no longer used, but the management is based on familiar concepts. The first consideration is the location of pain the next is the extent of distal symptoms. These issues are decided by the patient's report of present symptoms, which is defined as the pain that is their present problem. This applies to all symptoms being experienced even if not actually present at the time of assessment....

Cervical and thoracic zygapophyseal joint pain

Zygapophyseal or facet joint pain somatic dysfunction is a common diagnostic label used by manual therapists (Maitland 1986 Trott 2002 Gatterman 1998 McClune et al. 1998). This section explores what is documented, rather than speculated, about this syndrome in terms of diagnosis and treatment. Zygapophyseal joints are involved in the normal ageing process of cervical spondylosis, but changes such as anterior and posterior osteophytes, bony hypertrophy and foraminal stenosis are commonly found...

Consequences of postural neglect

The effects of postural habits have long-term implications on the human shape (McKenzie 1981, 1990). The commonly observed posture of protruded head, rounded shoulders and flattened spine may become habitual. As age advances, permanent postural 'set' may occur - head protruded, shoulders rounded, dowager's hump, loss of lumbar lordosis and the erect posture replaced by a slight stoop. This is likely to be accompanied by considerable soft tissue adaptations. Positions that are frequently...

Classification

Mechanical headaches are classified as derangement, dysfunction or postural syndrome. It should be recognised that mechanical syndromes may behave atypically when symptoms are primarily headache, which may be due to the unique anatomy of the upper cervical region. For instance, with derangement headache symptoms can be abolished, but not always easily reproduced. For this reason the original description involved a separate headache syndrome (McKenzie 1990). However, despite atypicality, certain...

Postural syndrome aggravating factor sitting

Sitting is the most common cause of pain in the posture syndrome. The individual with posture syndrome is exposed to long hours of sitting due to occupation, study, unemployment or hobby The postural habit when sitting for a period of time, and the effect this may have on symptoms, is best observed if the patient is seated without a back support as on the examination couch, rather than in a chair. Posture in sitting is often slumped, with no attempt to maintain an upright position actively The...

Effect of posture on symptoms in normal population

Harms-Ringdahl (1986) explored the effects of sustained slumped postures in volunteers without current or past neck symptoms. They maintained a posture of lower cervical and thoracic flexion and extreme upper cervical extension that is seen in a typical protruded head posture. All ten volunteers began to perceive pain within two to fifteen minutes, which increased with time, eventually forcing them to discontinue the posture after sixteen to fifty-seven minutes. Once they discontinued the...

Failure to remodel repair tissue

Following tissue damage, an important factor in the physiology of repair is the phenomenon of contracture of connective tissues. A characteristic of collagen repair is that it contracts over time. Recently formed scar tissue always shortens unless it is repeatedly stretched, this contracture occurring from the third week to the sixth month after the beginning of the inflammation stage. Contracture of old scar tissue may in fact occur for years after the problem originated (Evans 1980 Hunter...

Example of clinical reasoning process

In the following illustration some examples of the clinical reasoning process are given in italics. In this clinical example not all possibilities are explored the main emphasis is on trying to establish a mechanical diagnosis and appropriate management. The data gathered was relevant to this end and another clinician with an alternative perspective could have focussed on other aspects of the case. It should also be noted that the patient initially displayed a number of poor coping responses to...

Osteoporosis

Osteoporosis is the most common metabolic disorder affecting the spine. The suggested World Health Organisation definition is bone mineral density more than 2.5 standard deviations below the mean of normal young people (Melton 1997). According to this definition, approximately 30 ofpost-menopausal white women in the USA have the condition, and 16 have osteoporosis of the spine. Prevalence is less in non-white populations. Bone density decline begins in both sexes around 40 years of age, but...

Yellow flags

Term used to describe psychosocial risk factors for developing or perpetuating long-term disability or sick leave as a consequence of musculoskeletal symptoms. They include factors such as the attitudes and beliefs of the patient about their problem, their behavioural responses to it, compensation issues, inappropriate health care advice, information or treatment, emotions such as depression, anxiety and fear of movement, and relations with family and work. Adherent nerve root classification...

Management of mechanical cervical headache

If it has been established that the headache is cervical in origin and mechanical in nature by the previous test movements, management usually consists of postural advice and an exercise component. The exercise involves the movement thathasbeenfound to abolish or decrease symptoms for derangement and reproduce symptoms for dysfunction, whilst for postural syndrome, posture correction is the key component. The sequence below describes the normal force alternatives and force progressions that may...

Sustained loading and creep

Mechanical diagnosis and therapy makes use of the concept that different sustained postures (and movements) cause symptoms to decrease, abolish, centralise, produce, worsen or peripheralise. Certain therapeutic loading has a favourable effect on symptoms and should be encouraged, whilst other loading has an unfavourable effect on symptoms and should be temporarily avoided. Clues about this are gained during the history-taking, and these provide important pointers to management. The...

Fractures and dislocations

Fractures of the cervical or thoracic spine or ligamentous instabilities of the upper cervical spine may be caused by a variety of traumatic events, such as motor vehicle accidents, diving into shallow water, falling from a high place or a number of athletic activities. The thoracolumbar junction is reported as the most common site for non-osteoporosis-related spinal column fractures (Huler 1997). Fractures ofthe ribs may be caused by repeated muscular contractions. There are more reports...

Identification of serious spinal pathology

It is recommended that the same 'red flags' used to provide clues as to the existence of serious spinal pathology in patients with back problems be applied to patients with neck pain (Nachemson and Vingard 2000 Honet and Ellenberg, 2003). The recommendation exists because there is a lack of evidence with regard to 'red flags' for the cervical spine (Nachemson and Vingard 2000 Honet and Ellenberg, 2003). Minimal work has been done to evaluate the diagnostic accuracy, incidence or...

Mechanical diagnosis and therapy and headaches

Patients who attend musculoskeletal specialists with a primary complaint of headaches may be suitable for mechanical diagnosis and therapy. Patients who have a secondary complaint of headache, but a primary complaint of neck pain, are managed as explained in other parts of the book. Amongst those with primary headache it must be remembered that the symptom can indicate serious pathology, although rare, and such patients must always be screened for the existence of other 'red flag' features...

Specific questions

These questions serve three purposes. First, it gives us some idea about previous medical management and imaging studies for their neck problem. Second, this helps to bring to our attention any systemic or other conditions that may affect mechanical management or prognosis. Specific questions also raise questions about and explore any concerns we might have about serious spinal pathology as opposed to normal neck pain. With general medical questions, we need to know what drugs the patient takes...

Chronic pain interpretation of symptomatic responses

With chronic pain, peripheral tissue and central nervous system elements may be sensitised and deconditioned to normal movement the criteria of symptom response needs to be different. Under these circumstances normal mechanical stimuli can produce pain, repeated movements may have a 'wind up' effect on pain production, there may be a spread of painful areas, and there may be ectopic nociceptive signals (Dubner 1991 Johnson 1997). These changes make the interpretation of mechanically produced...

Assessment of the mechanical presentation

Neck pain has traditionally and anecdotally been viewed as being less dramatic in its effect on function thanback pain. Nonetheless, restrictions in normal function and range of movement are common in neck pain patients, especially if acute. Decreased movement compared to healthy controls and interference with usual activities of living and working are commonly reported in neck pain patients (Jordan et al. 1997 Hermann and Reese 2001 Hagen et al. 1997b Chiu and Lo 2002). Changes in these...

Tissue repair process

Following tissue injury, the process that in principle leads to recovery is divided into three overlapping phases inflammation, repair and remodeling (Evans 1980 Hardy 1989 Enwemeka 1989 Barlow and Willoughby 1992). No inflammation no repair is a valid dictum (Carrico et al. 1984). In fact, each part of this process is essential to the structure of the final result. Connective tissue and muscle do not regenerate if damaged, but are replaced by inferior fibrous scar tissue (Evans 1980 Hardy...

Dysfunction syndrome

In the dysfunction syndrome, pain is never constant and appears only as the affected structures are mechanically loaded. Pain stops almost immediately on cessation ofloading. When affecting articular structures, the dysfunction syndrome is always characterised by intermittent pain and a restriction of end-range movement. When affecting contractile structures, functional impairment is demonstrated when the muscle or tendon is loaded at any or certain points during the physiological range,...

What is whiplash

Whiplash is a familiar term to patients and clinicians. It generally denotes neck symptomatology that has commenced during or shortly after a motor accident. Strictly, the causal event for a true 'whiplash' injury is said to be a rear-end collision at a modest speed into a stationary vehicle in which the victim is facing forwards (Bogduk 1986). In practice, anyone involved in a car accident that develops symptoms is likely to be considered to have 'whiplash'. Neck pain that develops after a...

Cervical spine and vertebrobasilar insufficiency VBI Background

Traditionally a series of movements or positions thought to test the integrity of the vertebrobasilar arteries have been advocated prior to manipulation or mobilisation of the cervical spine (Maitland 1986 Grant 1994a McKenzie 1990). Such cervical procedures have sometimes been associated with complications, very rarely of a serious nature, such as death or cerebrovascular accident. The aim of the test movements and certain direct questions is to try to identify patients for whom this type of...

Cervical radiculopathy

For its management refer to Chapter 20, where it is included in the derangement category with referred arm pain below the elbow. The radiculopathy is most often attributed to...

Neuroanatomy of cervicogenic headache and experimental evidence

Ironically, despite remaining controversies regarding diagnosis, the neuroanatomical mechanism for cervicogenic headaches is one of the best understood (Bogduk 2001). Cervicogenic headache appears to be a form of referred pain from the upper three cervical segments (Bogduk 1994 Pollman et al. 1997) The mechanism for this is the 'trigeminocervical' nucleus in the upper part of the spinal cord (Bogduk 1994). Within this area, terminals from the trigeminal nerve and the upper three cervical nerves...
