BACKGROUND AND PURPOSE Physical therapists commonly attempt to reduce and prevent low back pain by "improving" individuals' lumbar posture. To investigate the physical therapy clinical practice of attempting to "improve" lumbar posture, measures of passive tissue stiffness and angular deformation during activities of daily living were used. PARTICIPANTS The lumbar spine posture of 150 univers...

OBJECTIVES To describe the distribution of prevalent syndesmophytes and bridges, and the occurrence of new ones in a prevalence cohort of patients with AS. METHODS Clinical and radiological data from 132 patients from the Outcome in Ankylosing Spondylitis International Study of which complete sets of radiographs were available at baseline and at 2- and 4-year follow-up were used. RESULTS At...

This article presents the evolution in medical history which leads to the surgical treatment for ruptured discs. Only at the last century the precise diagnosis of a ruptured lumbar disc could be made after tremendous efforts of the many medical pioneers in the study of the spine. The experience gained with the lumbar spine was rapidly transferred to the cervical spine. We describe the evolution...

Astronauts experience spine deconditioning during exposure to microgravity due to the lack of axial loads on the spine. Treadmill exercise in a lower body negative pressure (LBNP) chamber provides axial loads on the lumbar spine. We hypothesize that daily supine LBNP exercise helps counteract lumbar spine deconditioning during 28 days of microgravity simulated by bed rest. Twelve sets of health...

Radiologists are often plagued by limited time for completing their work, with an ever increasing workload [31]. A picture archiving and communication system (PACS) is a platform for daily image reviewing that improves their work environment, and on that platform for example spinal MR images can be reviewed. When reviewing spinal images a radiologist wants vertebrae labels, and in Sectra’s PACS...

STUDY DESIGN Cross sectional study. PURPOSE To determine the accuracy of the screening magnetic resonance study of the lumbar spine in the diagnosis of nerve root compression in cases of low back pain as compared to the routine magnetic resonance imaging (MRI) study of the lumbar spine. OVERVIEW OF LITERATURE No local study has been conducted for this purpose. In an international study, the...

Introduction: Previous studies of bone stresses in the human lumbar spine have relied on simplified models when modeling the spinal musculature, even though muscle forces are likely major contributors to the stresses in the vertebral bones. Detailed musculoskeletal spine models have recently become available and show good correlation with experimental findings. A combined inverse dynamics and f...

Use of lumbar spine imaging, particularly advanced imaging, continues to grow rapidly in the United States. Many lumbar spine imaging tests are obtained in patients who have no clinical symptoms or risk factors suggesting a serious underlying condition, yet evidence shows that this routine imaging is not associated with benefits, exposes patients to unnecessary harms, and increases costs. This ...
