![]() Spinal Pain: A School-based Epidemiological Study of ![]() Sagittal Standing Posture and its Association with The case studies suggest that intervertebral kinematic time-course data could have value in clinical assessments, lead to broader understanding of how specific anatomical features influence joint motions, and in due course inform clinical treatments. When applied to two patient cases, aberrant intervertebral motions in the cervical spine were typically found to correlate with patient-specific anatomical features such as disc height loss and osteophytes.

It may assist in the diagnosis, as well as suggest increased muscle tension/pressure as a possible etiology.Ī Videofluoroscopy-based Tracking Algorithm for Quantifying A straight neck without other radiographic abnormalities may be a major anatomical abnormality in fibromyalgia that has gone unnoticed. In fibromyalgia patients, the loss of cervical curvature was approximately 6.5 times greater than in control subjects (50.3% vs. In 83.2% of the patients, the cervical spine was essentially straight (Cobb angle ≤10 degrees). Most patients with fibromyalgia share an abnormality in common that is verifiable by a simple radiograph. The Cervical Spine: An Aid in the Diagnosis ofįibromyalgia and a Possible Clue to the Etiology Straight Neck Observed on a Lateral View Radiograph of The Vast Majority of Patients With Fibromyalgia Have a A recent study found this hyperkyphotic posture was associated with a 1.44 greater rate of mortality. Persistent forward head posture ( a.k.a “hyperkyphotic posture”) puts compressive loads upon the upper thoracic vertebra, and is also associated with the development of Upper Thoracic Hump, which can devolve into Dowager Hump when the vertebra develop compression fractures (anterior wedging). Spinal Alignment and Cervical Curve Articles A line under the bottom of the C2 body (Whitehorn's line) should be parallel with the floor. The normal Atlas Plane line would be 18–24 degrees superior to the bottom of the film. If it crowds C2, it is labelled “superior”. If C1's posterior arch “crowds” occiput, it is labelled as an “inferior” Atlas. The posterior arch of Atlas should be centered in the space between occiput and the C2 spinous process. This is easily measured with the AcuArc ruler. The normal cervical lordosis (which extends from C1 to T2) should have a 17–24 cm. Positioning of the head and spine should also be assessed for anterior head placement (also known as Forward Head Posture). There should be an even spacing between each spinous process. All segments should be on Georges's line (one curved line). The picture on the left is an example of perfect cervical lordosis. (See Figure 2) Note that ALL the vertebra should be on this curved line, with a radius between 17–24 cm., depending on patient height. (See Figure 1 + 2) Then set the compass on that radius center-point, and use that same chord length to strike the radius of the cervical curve at the anterior vertebral bodies. Now, swing arcs back from the C1 and T2 points, with the compass set using the chord length, to locate the point which will describe the optimum spinal curve. This length becomes the “chord” length of that patient's curve. Set your compass for the distance between theseĢ points. Dot the anterior superior aspect of theģ. To define the cervical curve of the spine with a compass:Ģ. Thus, a reduced cervical curve may result in a 50% reduction in the overall resistance of the spine to axial stress. If we lose the cervical or lumbar curves, the formula is Thus, the spine'sĪbility to resist axial stress, taking into account the cervical, thoracic and lumbar curves is: The lordotic cervical & lumbar spine are the basis of the spine's ability to resist axial stressors.” A resistance factor in mechanical structure is expressed by the formula:Īnd C = the number of curvatures. “ Clinical Chiropractic Biomechanics” states, “Spinal biomechanical stability requires an optimal lordotic structure. The normal cervical lordosis (which extends from C1 to T2) should have aġ7–24 cm. Chiropractic analysis should be aimed at locating the specific segments which are subluxated, as well as providing the means to “free” those segments. Abnormal stresses occur in the facets, discs and supporting tissues when normal motion of the spine is impaired. Loss of structural integrity and/or normal function of the spine is the basis for the evolution of the vertebral subluxation. Painter, D.C.Īlternative Medicine Approaches to Disease
