STUDY DESIGN A randomized, controlled trial, test--retest design, with a 3-, 6-, and 30-month postal questionnaire follow-up. OBJECTIVE To determine the efficacy of a specific exercise intervention in the treatment of patients with chronic low back pain and a radiologic diagnosis of spondylolysis or spondylolisthesis. SUMMARY OF BACKGROUND DATA A recent(More)
OBJECTIVE To quantitatively describe the postural alignment of the head and shoulders and the surface curvature of the thoracic spine in comfortable erect standing and to examine the effect of age and gender on head and shoulder alignment. DESIGN Descriptive survey. SETTING Gait research laboratory. PARTICIPANTS One hundred sixty asymptomatic(More)
In a controlled clinical trial, we allocated 48 subjects with acute low back pain but without neurological signs, at random to two treatment groups. The conservative treatments compared were passive mobilisation and manipulation of the lumbar spine and a regimen of microwave diathermy, isometric abdominal exercises and ergonomic instructions. The duration(More)
Reduction of stature in old age has been attributed to loss of disc height. A measurement study of 204 cadaveric lumbar spines from subjects ranging in age from one day to 97 years confirmed data on loss of "spinal stature" but could not confirm a loss of disc height. With aging, there is a progressive increase in vertebral end-plate concavity, associated(More)
The articular triad of the intervertebral disc and the two synovial zygapophyseal joints at the same vertebral level, allows the spine its considerable mobility, while providing support and protection. The principal structural changes which occur to the elements of the articular triad in old age are an increase in the convexity, central height and(More)
The intent of this study was to describe the effects of long term paraplegia and wheelchair use on upper limb function. Bilateral upper extremity isokinetic and grip strength, pain, and active range of motion were compared in 52 men with paraplegia (mean age 44 years; mean duration of spinal cord injury (SCI) 17 years) and 52 age and activity level matched(More)
Common clinical beliefs about the relationship between postural characteristics and pain are based on mainly anecdotal evidence. This study examined the reliability of physical characteristics of the head, shoulders and thoracic spine and identified relationships among them. Measurements were made from photographs of subjects in comfortable erect standing.(More)
OBJECTIVE To report the outcome of a multidisciplinary physically based program to treat sufferers of chronic low back pain who had not responded to previous treatment. DESIGN Prospective intervention study. SETTING The treatment program was conducted at the private practice of Brian C Edwards and Associates Rehabilitation Centre. PATIENTS A total of(More)
Thirty victims of blunt cervical trauma, who did not survive (acute death group), were studied at autopsy as were 11 patients who survived trauma for more than 1 month and ten controls without any known cervical trauma. All specimens were sagitally sectioned in 2-mm slices and carefully examined for injuries to the lateral parts of the atlanto-axial joints.(More)
Facet arthrograms in patients with lumbar spondylolyses show spread of contrast medium through pars interarticularis defects into the adjacent ipsilateral facet joint space and across the midline into the contralateral joint space. Transverse and sagittal sections of facet joints from 141 postmortem lumbar spines were studied. Five examples of spondylolysis(More)
