The Study: Cervical spine alignment, sagittal deformity, and clinical implications: a review The Facts: a. The authors reviewed normal cervical alignment, how to measure cervical alignment in the sagittal plane and the effect of cervical misalignment (cervical kyphosis in this case) on health-related quality of life (HRQOL). b. Recent studies suggest a correlation between cervical […]

Review article Ames CP, et al. Spine (Phila Pa 1976). 2013. Abstract STUDY DESIGN: Narrative review. OBJECTIVE: To provide a comprehensive narrative review of cervical alignment parameters, the methods for quantifying cervical alignment, normal cervical alignment values, and how alignment is associated with cervical deformity and myelopathy with discussions of health-related quality of life. SUMMARY […]

Eur Spine J. 2011 Sep; 20(Suppl 5): 609–618. Published online 2011 Aug 2. doi: 10.1007/s00586-011-1928-x PMCID: PMC3175914 PMID: 21809016 Pierre Roussouly Abstract Introduction Standing in an erect position is a human property. The pelvis anatomy and position, defined by the pelvis incidence, interact with the spinal organization in shape and position to regulate the sagittal […]

Kobayashi T Abstract In a 12-year prospective study of 100 adult volunteers, incident vertebral fractures were analyzed for potential predictors. Decreased sagittal spinal curvature and pre-existing fractures were identified as independent predictors. The risk of vertebral […]
Abstract BACKGROUND Although practice protocols exist for SMT and functional rehabilitation, no practice protocols exist for structural rehabilitation. Traditional chiropractic practice guidelines have been limited to acute and chronic pain treatment, with limited inclusion of functional and exclusion of structural rehabilitation procedures. OBJECTIVE (1) To derive an evidence-based practice protocol for structural rehabilitation from publications […]
Journal of Biomechanics Volume 38, Issue 6, June 2005, Pages 1313-1323 Brian D.Stemper Abstract Although considerable biomechanical investigations have been conducted to understand the response of the cervical spine under whiplash (rear impact-induced postero-anterior loading to the thorax), studies delineating the effects of initial spinal curvature are limited. This study advanced the hypothesis that abnormal […]
J Manipulative Physiol Ther. 2005 Mar-Apr;28(3):187-93. McAviney J1, Schulz D, Bock R, Harrison DE, Holland B. Abstract OBJECTIVE: To investigate the presence of a “functionally normal” cervical lordosis and identify if this and the amount of forward head posture are related to neck complaints. METHODS: Using the posterior tangent method, an angle of cervical lordosis was measured from C2 through C7 vertebrae on 277 lateral cervical x-rays. Anterior weight bearing […]
Harrison DE, et al. Eur Spine J. 2005. Abstract In the absence of external forces, the largest contributor to intervertebral disc (IVD) loads and stresses is trunk muscular activity. The relationship between trunk posture, spine geometry, extensor muscle activity, and the loads and stresses acting on the IVD is not well understood. The objective of […]

J Bone Joint Surg Br. 1994 Jan;76(1):103-6. Helliwell PS, Evans PF, Wright V. Abstract The loss of cervical lordosis in radiographs of patients presenting with neck pain is sometimes ascribed to muscle spasm. We performed a cross-sectional study of the prevalence of ‘straight’ cervical spines in three populations: 83 patients presenting to an accident department […]
