spinal rotation definition
His method incurred least systematic error, but greatest random error. California Privacy Statement, While numerous vertebral rotation measurement methods have been developed and tested, thorough comparisons of these are still relatively unexplored. What Causes Pain in the Lower Right Part of Your Back? A good injury prevention exercise program will also work your hip and pelvic muscles, too. Department of Surgery, University of Alberta, Edmonton, T6G 2B7, Canada, Gabrielle C Lam, Doug L Hill, Jim V Raso & Edmond H Lou, Department of Rehabilitation Technology, Glenrose Rehabilitation Hospital, Alberta Health Services, Edmonton, T5G 0B7, Canada, Department of Radiology and Diagnostic Imaging, University of Alberta, Edmonton, T6G 2B7, Canada, You can also search for this author in Furthermore, accuracy of CT measurements is more severely affected by inclination and tilt, outweighing limitations encountered with radiographic measurement of large rotations when considering realistic conditions. spinal - WordReference English dictionary, questions, discussion and forums. Rotated or twisted vertebrae, especially when bending forward—as when lifting heavy objects—is associated with a risk of back injuries like strain and herniated disc. 10.1097/00007632-199710150-00016. EL conceived of the study, coordinated the project and edited the manuscript. Low Back Pain Fact Sheet. Google Scholar. Google Scholar. 10.1016/0021-9290(76)90113-5. − Here’s how to do it. Current research has provided a more comprehensive understanding of Adolescent Idiopathic Scoliosis (AIS) as a three-dimensional spinal deformity, encompassing both lateral and rotational components. Rotation prone on the Arc barrel is an easy-to-do, therapeutic exercise. b Journal of Spinal Disorders. 1999, 59: 316-320. This challenge is more inconclusive, although Weiss noted that their effect on measurement accuracy was insignificant when studying the apical vertebra. When you move your spine, each individual vertebrae affects the direction of the entire spinal column. July 1997. [46, 47]. Stokes reported similar accuracy, with the added advantage of one fewer x-ray exposure and a less complicated measurement scheme . 1997, 22 (20): 2403-2407. These changes are largely attributable to sedentary behavior.. × Scoliosis. Stokes' method accounted for vertebral asymmetry and dimension by determining pedicle-offset with respect to a center point rather than the vertebral edges. Google Scholar. Despite many advantages of this technology, radiographic methods remain most standard, to which current developing techniques are compared for evaluating their accuracy [27, 38–41]. Journal of Spinal Disorders. Furthermore, the hazardous health implications associated with frequent and prolonged exposure to radiation has been of primary concern for scoliotic patients, who are often undergoing critical growth and developmental stages. Microscopic analysis of muscles. ( Stud Health Technol Inform. Krismer M, Bauer R, Sterzinger W: Scoliosis correction by Cotrel-Dubbousset instrumentation: The effect of derotation and three dimensional correction. Cookies policy. The position of the spinous process (Cobb method) [ 22 ], pedicle shadows (Nash and Moe, Perdriolle, Drerup, Stokes method) [ 9, 10, 23 – 25 ], or a combination of landmarks (Mehta) [ 26] in relation to the vertebral body are often clinically used to quantify the extent of vertebral rotation. Studies in Health Technology and Informatics: Research into Spinal Deformities 1. This review discusses the advantages and disadvantages of six common measurement techniques based on technology most pertinent in clinical settings: radiography (Cobb, Nash-Moe, Perdriolle and Stokes' method) and computer tomography (CT) imaging (Aaro-Dahlborn and Ho's method). Ho et al reported higher intraobserver and interobserver errors in the use of the Aaro-Dahlborn method when compared to their technique . Cole AA, Burwell RG, Webb JK: Lateral flexion induced axial rotation in adolescent idiopathic scoliosis (AIS). Spine.
