CONTEXT: Somatic dysfunction is diagnosed by the presence of any of 4 TART criteria: tissue texture abnormality, asymmetry, restriction of motion, or tenderness. OBJECTIVE: To measure the prevalence of somatic dysfunction in patients with chronic low back pain (LBP) and to study the associations of somatic dysfunction with LBP severity, back-specific functioning, and general health. DESIGN: Cross-sectional study nested within a randomized controlled trial. SETTING: University-based study in Dallas-Fort Worth, Texas.

A case of sacroiliac syndrome and lumbar facet capsulitis coexisting with an asymptomatic grade II spondylolisthesis is presented. Spinal manipulative therapy is not contraindicated in the presence of spondylolisthesis if specific to the site of joint hypomobility and if the underlying spondylolisthesis is stable. Manipulation may prove to be diagnostic as well as therapeutic. The need to clinically assess whether the spondylolisthesis is symptomatic is discussed.

Metastatic disease of the lumbar spine is a relatively common, but catastrophic cause of low back pain. Because of an increasing role as primary care providers for back pain patients, it is essential that chiropractors keep this possibility in mind. Careful consideration of the patient's history, physical and laboratory findings, and the use of imaging procedures are helpful in establishing a correct diagnosis in those cases where metastasis is suspected.

There remains a lack of definitive evidence regarding the etiology of pars defects, though evidence is mounting in favor of micro-trauma. Approximation of the articular facets, as occurs in subjects with increased sacral base angles, may result in greater stress to this area, leading to the development of pars defects. Alternatively, pars defects may facilitate approximation of the articular facets, resulting in a higher sacral base angle. The purpose of this study was to determine whether persons with spondylolysis have greater sacral base angles compared to persons without spondylolysis.

OBJECTIVES: To evaluate plain film radiographic findings of lumbar intervertebral disk degeneration. DESIGN: A cross-sectional observational design was employed. Contingency tables were constructed to evaluate the relationships between radiographic findings of degeneration and the corresponding MRI signal intensities of the inner intervertebral disk. SETTING: Twenty-four consecutive cases were retrospectively selected from an MRI imaging center. PATIENTS: No exclusion was made on the basis of age or sex.

OBJECTIVE: To examine the role of oblique-axis sacral torsion in the presence of true or apparent short leg. DESIGN: Prospective blind trial of eighteen subjects. SETTING: A suburban chiropractic practice, a hospital and a university campus. SUBJECTS: Of 33 subjects selected, 27 completed the study, 8 exhibited elimination criteria, and 1 X-ray was nondiagnostic. MAIN RESULTS: 3 x 3 contingency table showed the presence of unilateral sacral prominence as statistically significant (p > .001) in subjects with LLI.

OBJECTIVE: Reports of complications after chiropractic adjustments were administered to the lumbar spine and/or pelvis are rare. This case report provides the events associated with a sacral fracture that was not identified before a side-posture sacroiliac adjustment. CLINICAL FEATURES: The patient suffered from blunt, low back trauma as a result of a fall. Clinical evaluation indicated fixation dysfunction at the left sacroiliac articulation, with minimal edema/tenderness at the inferior portion of the left sacroiliac joint.

The aim of this clinical investigation was to determine whether the abnormal H-reflex complex present in patients with S1 nerve root compression due to lumbosacral disc herniation is improved by single-session lumbar manipulation. Twenty-four patients with unilateral disc herniation at the L5-S1 level underwent spinal H-reflex electro-physiological evaluation. This was carried out before and after single-session lumbar manipulation in the side-lying position.

Cranial bone motion continues to stimulate controversy. This controversy affects the general acceptance of some intervention methods used by physical therapists, namely, cranial osteopathic and craniosacral therapy techniques. Core to these intervention techniques is the belief that cranial bone mobility provides a compliant system where somatic dysfunction can occur and therapeutic techniques can be applied. Diversity of opinion over the truth of this concept characterizes differing viewpoints on the anatomy and physiology of the cranial complex.

STUDY DESIGN: An in vivo biomechanical study of three separate manipulation procedures administered in random order. A biomechanical computer model estimated the loads passing through the spine at the level of interest. OBJECTIVES: The difference in loading effects from manipulation were contrasted for all six degrees of freedom based on treatment method. Quantitative information was compared with loads predicted by existing biomechanical models for work tasks in materials handling jobs.
