Book: Advanced Osteopathic Technique: Chapter Contents

Chapter One: An introduction to Sacroiliac and Spinal Articulation

This important chapter provides the formulae for sacroiliac and spinal articulation together with overview of the principles that govern sacroiliac and spinal joints articulation. It also explains how the synergetic theories fit in with research. There is an introduction into the ‘G’ and ‘M’ forces.


Chapter Two: Physiology of the sacroiliac joints

This chapter explains more about the architecture of the sacroiliac joints and how the sacroiliac joints articulate without semi-dislocation. It shows how and why the anatomy of the sacroiliac facets compliment the contours of the spinal facets during articulation.  


Chapter Three: Physiology of the lumbar Joints

This chapter explains the anatomy and physiology of the lumbar vertebrae. It explains with examples how the lumbar facet anatomy fits in with the sacroiliac facet contours.  And most importantly the mechanics and function of L1.


Chapter Four: Physiology of walking

This chapter explains in detail how the lumbar and sacroiliac joints work in harmony with each other to produce forward and backward ambulation.


Chapter Five: Physiology of the thoracic joints

This chapter explains the anatomy and physiology of the thoracic vertebrae. It shows how the thoracic joints integrate with the sacroiliac joints and how they integrate with the ribs in a way that allows articulation and breathing. It explains why it is physiologically impossible to extend the thoracic spine and rotate at the same time and how and why L1 blocks this movement.


Chapter Six: Physiology of the cervical joints

This chapter explains the anatomy and physiology of the thoracic vertebrae.


Chapter Seven: L3 left-right flexion lesions of the lower back

This chapter explains how flexion lesions in the lumbar are created when the forces that create normal articulation are misdirected. It explains how bony subluxations turn into Osteopathic lesions. It explains the knock on effect each lesion has on its surrounding joints and how they form a characteristic posture dysfunction. It further explains the pelvis then becomes distorted so that all lesions above are reinforced every time the legs are weight bearing.    


Chapter Eight: L3 right-right extension lesions of the lower back

This chapter explains how extension lesions in the lumbar are created when the forces that create normal articulation are misdirected. It explains how bony subluxations turn into Osteopathic lesions. It explains the knock on effect each lesion has on its surrounding joints and how they form a characteristic posture dysfunction. It further explains the pelvis then becomes distorted so that all lesions above are reinforced every time the legs are weight bearing.  


Chapter Nine: Lesions of the  thoracic joints

This chapter explains how extension and flexion lesions in the thoracic joints are created when the forces that create normal articulation are misdirected. It explains how bony subluxations turn into Osteopathic lesions. It explains the consequences that take place when lesions in L1 take place. It explains how backward extension lesions are mutated into what he old Osteopaths called a complicated lesion. It explains the knock on effect each lesion has on its surrounding joints and how they form a characteristic posture dysfunction.


Chapter Ten: Lesions of the cervical joints

This chapter explains how the cervical joints can become so tightly locked against each in either extension or flexion lesions to and osteopathic lesion.


Chapter Eleven: The two models

This chapter shows how to differentiate the two models. Each model is based on how L3 became lesioned I.e right-right or left-right. It shows how to evaluate your patient visually by looking for tell tale landmarks and what to look for on palpation. Correct diagnosis is essential when you manipulate with PPT’s.


Chapter Twelve: From spinal mechanics to manipulation

This chapter shows the importance of manipulation and why muscle based therapies can never expect to correct the misalignment of the pelvis, the sacroiliac, the spinal and the ribs joints. It recaps how joints become lesioned.


Chapter Thirteen: PPT manipulation

This chapter shows the principles that make PPT’s so powerful. It shows a variety of techniques on different parts of the spine. It shows how to safely correct neck lesions with the head straight and in the mid-line with minimal force, and characteristic of PPT’s, no click. It also shows how to correct pelvic lesions and the best strategy to make sure you are able to correct  lesion every time.


Chapter Fourteen: Physiology of the rib cage

This chapter explains the anatomy and physiology of the ribs and how they articulate with the thoracic vertebrae. It explains how ribs are kept in the parallel to allow unhindered breathing whilst the host joints rotate and side-bend.


Chapter Fifteen: Physiology of the manubrium and clavicle

This chapter explains the anatomy and physiology of the manubrium and clavicle and how they are articulate in harmony.


Chapter Sixteen: Physiology of the acromio-clavicular joint and scapula

This chapter explains the anatomy and physiology of the acromio-clavicular joint and scapula and how they are articulate in harmony.


Chapter Seventeen: Rib cage and clavicle lesions

This chapter explains how lesions are created in the ribs and the lesions they cause to the surrounding joints. It shows how the rib cage,clavicle and manubrium distort and create the distorted posture seen in the two models.


Chapter Eighteen: Rib cage manipulation

This chapter explains the position ribs become lesioned  and how to correct them using PPT’s.


The above summaries are just the headings for the subjects covered in ‘Advanced Osteopathic Technique’. Each chapter contains much more and is rich with illustration and useful information.
