Restoration of Pediatric Cervical Lordosis CBP® NP #47 The cervical lordosis is a normal postural development that occurs as early as 7-9.5 weeks in utero. This study by Chiropractic BioPhysics or BCP researchers reviewed the existing literature for any ad all peer-reviewed evidence of any chiropractic technique system that has documented an improvement of cervical lordosis in pediatric patients (age less than 18 years). 10 Publications were included for review; only 6 reported an x-ray measurement documenting the increase in cervical curve resulting from treatment; the other 4 papers merely commented on a post-treatment improvements in lordosis. Only 4/10 studies used a reliable measurement method; that being the Harrison posterior tangent method.
Thoracic Kyphosis Optimized Elliptical Model & Alignment Data CBP® NP#49 Abnormal Thoracic Kyphotic curvature is a causative / associated factor in a variety of human health, disease, and disability situations. However normal geometric models of the shape of kyphosis are rare. This study by Chiropractic BioPhysics researchers investigated Thoracic kyphosis of 50 optimized lateral full-spine radiographs to obtain the mean thoracic kyphosis. Global and segmental angles were determined. Computer iteration processes passed geometric shapes through the posterior body coordinates of the mean thoracic kyphosis to determine the best fit model in the least squares sense. The T1 and T12 areas tended to be flatter in curvature when compared with T2-T11, indicating these are inflection points between the cervical and lumbar lordotic curves. The T2-T11 kyphotic region was closely modeled with approximately a 72 degree portion of an ellipse. Vertebral body and disc dimensions fluctuated as would be expected in normal variations of human anatomy. However, these fluctuations had limited effect on segmental and total angles of Thoracic Kyphosis. This elliptical model can be used by clinicians and researchers for normal values against which to compare patient populations too and to use an estimate goal of non-surgical and surgical spine rehabilitation.
