Mechanics and Treatment of the Sacroiliac Joint
Richard L. Don Tigney, PT
Abstract: Dysfunction of the joint is as far common than has been suspected and may mimic disc disease or give the impression of a multifactorial etiology. Details of the anatomy, biomechanics and pathomechanics are presented enabling clinicians to better understand the function of the sacroiliac joint in different postures and during locomotion. The clinical assessment of sacroiliac dysfunction is presented and suggested treatment techniques are discussed.

Biomechanics of the Thorax: A Clinical Model of in Vivo Function
Diane Lee, BSR, MCPA, COMP
Abstract: A clinical model of the in vivo biomechanics within the thorax is proposed. The relative motion of the thoracic vertebrae and the associated ribs both as moving bones ( osteokinematics ) and moving joints ( arthrokinemechanics ) is considered during sagittal, coronal and transverse motion of the trunk. Flexion and extention of the thorax induces anterior / posterior translations together with slight vertical translation of the vertebral elements. Simultaneously the ribs anteriorly / posteriorly rotate at the costotransverse joints. Side flexion and rotation can occur both to the same side and to the opposite side in the midthorax and the lower thorax. The first pattern of motion occurs during axial rotation of the trunk while the latter occurs during lateral bending. The ribs rotate anteriorly on one side and poseriorly on the other during both lateral bending and axial rotation of the trunk. A clinical hypothosis of the mechanism which produces the coupling movement patterns is discussed.

A preliminary Investigation of the Relationship between Lumbar Postero-anterior Mobility and Low Back Pain
Debra Shirley, BSc, GradDipPhys, GradDipManipTh Michael Lee, BE, BappSc(Phty), MbiomedE
Abstract: It is widely assumed that there is a relationship between pain, stiffness and the muscle activity in patients with low back pain. This preliminary study was designed to begin an investigation of the existence of this relationship. Two subjects with low back pain and six normal subjects participated. The posteroanterior mobility of L3 and L4 was measured together with lumbar extensor muscle EMG. All normal subjects showed negligible muscle activity whereas both low back pain subjects demonstrated elevated EMG levels. In addition, both low back pain subjects were found to have relatively low mobility of L3 and L4 as compared to the normal subjects. Further research to investigate the relationship between the variables indicated.
