Back Pain: a movement problem is a practical manual to assist all students and clinicians concerned with the evaluation, diagnosis and management of the movement related problems seen in those with spinal pain disorders. It offers an integrative model of posturomovement dysfunction which describes the more commonly observed features and related key patterns of altered control. This serves as a framework, guiding the practitioner's assessment of the individual patient.

• Examines aspects of motor control and functional movement in the spine, its development, and explores probable reasons why it is altered in people with back pain
• Maps the more common clinical patternsof presentation in those with spinal pain and provides a simple clinical classification system based upon posturomovement impairments
• Integrates contemporary science with the insights of extensive clinical practice
• Integrates manual and exercise therapy and provides guiding principles for more rational therapeutic interventions:
• • which patterns of movement in general need to be encouraged
  • which to lessen and how to do so
• Abundantly illustrated to present concepts and to illustrate the difference between so-called normal and dysfunctrional presentations
• Written by a practitioner for practitioners

Chapter 1 Introduction

Back pain is usually a symptom of dysfunction in the musculoskeletal system.

Janda¹ suggests that pain, however undesirable, serves an important biological function acting as a warning signal that all is not well in the movement system. It may be functioning in a harmful way and rather like the warning light on your dashboard reminding you the car needs a service, pain heralds the ‘tipping point’ in a continuum of dysfunction. Addressing the dysfunction will generally ameliorate the pain. However, classical Western medicine has by and large tended to view pain within a ‘disease model’, hunting for ‘the pathological’ structure in order to arrive at diagnosis and ‘fix it’. As we all know, the results have been less than promising and there is now a shift towards the possibility that disturbed function may be more important than structural damage as the physical basis of back pain.¹ When the dysfunction and pain continue unabated, secondary factors such as disability and psychosocial factors begin to create a complex picture of interlocking dysfunctions. The ‘biopsychosocial model of dysfunction’² acknowledges the multifactorial nature of the ‘problem of back pain’ and contemporary treatment approaches generally embrace addressing each aspect as indicated.

Back pain is fundamentally a physical problem and the focus of this book is to primarily address the ‘bio’ aspect – the physical perspective of back pain.

Gracovetsky³ has said ‘restoring the function of the injured patient implies knowing what the normal function is, something which is still the subject of speculation’. In similar vein, Van Dieën⁴ states ‘the relationship between low-back pain and motor behavior is poorly understood. Consequently the (para) medical disciplines involved lack a theoretical basis for treatment and outcome evaluation’. Moseley⁵ asks ‘what is it about pain that changes the way people move?’ Conversely, one could ask: ‘what is it about the way people move that causes pain?’

The aim in this work is an attempt to assist the understanding of normal movement function and the nature of movement dysfunction seen in spinal pain patients. Understanding how and why movement is altered goes a long way towards effectively redressing it.

An integrative model of neuromusculoskeletal dysfunction is offered as both a theoretical and a practical framework to aid the understanding of dysfunction and enhance current clinical practice skill. It describes the consistently observed, more common altered patterns of postural and movement control seen clinically in patients with spinal pain and related disorders. While each person with back pain presents individually, we can observe the tendency for common features which can be collated into a general paradigm of dysfunction. In general, the kinematic patterns of movement adopted during the simple repetitive activities of daily living are altered as a result of changed posturomovement control, and contribute to repetitive microtrauma and ‘injury’. Most back pain is a developmental movement disorder – a simple event often called an ‘injury’ can end up being a major problem. This helps explain the development and perpetuation of pain and related symptoms.

The model is somewhat of a paradigm shift – one of functional adaptation and maladaptation of posturomovement control as a common underlying genesis of most spinal pain disorders. It also provides a clinical classification system based upon posturomovement dysfunction providing a framework guiding assessment and management. Without a conceptual practical framework, there is a risk that ‘evidence based research’ is often misinterpreted and inappropriately applied to all patients regardless of that patient's presenting dysfunction. The aim of treatment interventions, both manual and therapeutic exercise, is to restore function. Manual treatment is necessary initially to alleviate pain and help normalize the local neuromuscular dysfunction. Retraining control of movement protects the spine against reoccurrence and helps restore function.

An appreciation of these more common changed responses in motor control helps to formulate the choices and enhance the quality of teaching therapeutic exercise in the rehabilitation of spinal musculoskeletal pain syndromes. We are seeing a larger group of patients presenting with symptoms resulting from, or exacerbated by, inappropriate exercise therapy. Hopefully an improved understanding of the problem can help rescue and refine the art of exercise therapy.

The work has emanated from the fruits of over 40 years of extensive clinical practice, scientific ‘evidence’ to hand and the diverse influences of inspired thinkers within the realms of therapeutic practice and somatic movement education. The clinical practice combination of manual therapist and movement educator has helped in seeing and understanding the relationships between joint and myofascial dysfunction and movement disorders. Conducting therapeutic exercise and movement classes has provided more opportunity for observing and recognizing certain ‘patterns’ of response which appear to be somewhat common in people with a history of spinal pain disorders.

Significantly however, by our observation, it appears that the boundary between ‘normal’ and abnormal movement function is often quite blurred and dysfunction may represent subtle variations from normal.⁶ Similar patterns are often evident, albeit less marked, when observing the general public: students in a yoga class or similar exercise forum perhaps reflect common underlying tendencies in us all and which, when more pronounced, contribute to the development of pain syndromes. The presence of pain further compounds the dysfunction. Janda noted ‘the high incidence of functional impairment makes it extremely difficult to estimate the borders between the norm and evident pathology’. The prevalence of low back pain appears to be on the rise in affluent urbanized countries.⁷

This book is addressed to the clinician to practically assist in the physical aspect of the management of patients with spinal pain disorders. It attempts to examine and provide an overview of ideal normal movement function of the torso and the functional interrelationship of its parts. This includes the significant aspects of normal motor development and the important qualities in normal movement control. It also describes the commonly observed inefficient patterns of axial muscle control and the close relationship between these and the development of changed articular function and pain syndromes.

Chapter 2 The problem of back pain

Just about any book or paper you read on low back pain (LBP) introduces the subject by restating the fact of the increasing ‘epidemic’ of low back pain and its enormous cost to society. We can fly man to the moon yet despite the advances of modern science the effective diagnosis and treatment of back pain remains somewhat of an elusive dilemma. Is it perhaps a case of losing sight of basic principles? To utilize Feldenkrais’¹ term, is it missing ‘the elusive obvious’?

According to Janda,² excluding insidious pathology, most musculoskeletal pain is the result of impaired function in the motor system. Pain serves an important biological function,

It might even be said that the motor system suffers from our whims and thus has no other way of protecting itself than by producing pain’.²

The Eastern medical paradigm would tend to view pain as a valuable sign signalling harmful overstress in the system. Western medicine has had a vested interest in treating pain as a disease and back pain has certainly become this.

The diagnosis dilemma

Waddell³ says: ‘only with the introduction of western medicine does chronic back disability become common’. The approach of contemporary medicine is to search for a ‘pathological’ diagnosis, the cornerstone for instituting appropriate treatment. However, definite structural pathology is only evident in about 15% of patients with back pain.^3-5 The relationship between imaging and symptoms is weak.^4,6 There are inherent lim...
