Background: Biomechanical analysis of the sagittal alignment of the lumbar spine and pelvis on radiographs is common in clinical practices including chiropractic, physical therapy, scoliosis-related thoraco-lumbo-sacral orthosis (TLSO) management, orthopedics, and neurosurgery. Of specific interest is the assessment of pelvic morphology and the rel...

(1) Background: This study assessed the relationship between cervical spine parameters taken on standing full-spine lateral radiographic images compared to sectional lateral cervical radiographs. (2) Methods: Full-spine (FS) and sectional lateral cervical (LC) radiographs from four spine treatment facilities across the USA retrospectively provided...

Background: Measures of lumbar lordosis (LL) and elliptical modeling variables have been shown to discriminate between normal and chronic low back pain (CLBP) patients. Pelvic morphology influences an individual’s sagittal lumbar alignment. Our purpose is to investigate the sensitivity and specificity of lumbar sagittal radiographic alignment and m...

Background: Forward head posture (FHP) and altered cervical lordotic curvatures are common spine displacements often associated with neck pain and disability. Two primary categories for determining FHP exist: radiographic and postural measurements. Methods: This study investigated the correlation between the craniovertebral angle (CVA), the radiogr...

Background: Biomechanical analysis on the alignment of the sagittal lumbar spine and pelvis, particularly in assessing pelvic morphology and the relationship with sacral slope and lumbar lordosis, is common in clinical practice including in chiropractic care and orthopedic surgical planning. The current state of the literature on the reliability of...

Fears over radiation have created irrational pressures to dissuade radiography use within chiropractic. Recently, the regulatory body for chiropractors practicing in British Columbia, Canada, the College of Chiropractors of British Columbia (CCBC), contracted Pierre Côté to review the clinical use of X-rays within the chiropractic profession. A "ra...

[Purpose] To present the case of the dramatic reduction in pain, disability, and neurologic symptoms following the reduction of forward head translation and increased cervical curvature in a patient suffering from post-surgical radiculopathy. [Subject and Methods] A 52-year-old male mechanic presented with chronic neck pain, unilateral paresthesia...

[Purpose] To present the clinically significant improvement of straight back syndrome (SBS) in a patient with spinal pain and exertional dyspnea. [Subject and Methods] A 19 year old presented with excessive thoracic hypokyphosis and other postural deviations. A multimodal CBP® mirror image® protocol of corrective exercises, traction procedures and...

Background: Many US insurance companies, managed care organizations, chiropractic researchers, and chiropractic academics claim that, if low back pain resolves with Spinal Manipulative Therapy (SMT), it does so in 6 to 12 visits. Objective: To determine the validity of claims that low back pain should resolve in 6 to 12 visits with Spinal Manipula...

Objective: To determine the validity of claims that headaches, neck pain, and upper back pain should resolve in 6 to 12 visits with Spinal Manipulative Therapy (SMT) or Mobilization and to derive an evidence-based Frequency and Duration program for these conditions. Methods: Searches were performed in PubMed, CINAHL, Mantis, and the Index of Chiro...

It is our collective opinions that Dr. Troyanovich continues to misrepresent Chiropractic history by not giving credit to Drs. Don and Deed Harrison for their multiple original ideas that span three decades.

In summary, Pettibon and Langworthy performed longitudinal traction. Dr. Don Harrison in 1981 was the originator of extension cervical traction to restore cervical lordosis. In the mid 1990’s, Dr. Deed Harrison was the originator of lumbar extension traction to restore posture and restore the lumbar lordosis. Dr. Coleman did not originate anything...

Conclusion Unlike what Troyanovich and Coleman wrote (“refer the interested reader to our Chiropractic History article(2) to allow him/her to decide for themselves the accuracy of this matter”), since it appears that they have a history of distorting the facts, we suggest the reader not go to their summaries, but go to the actual texts and the page...

Objective: To delineate the history of spine traction in the literature. Data Collection: A hand search of available reference texts and a computer search of literature were performed on traction in the Indexed Medicus, CINAHL, Index to Chiropractic Literature, and Mantis sources. Results: Reviewed material indicates that most traction studies were...

To determine projected Cobb angles associated with trunk list (side shift) posture, hypothesizing that the side shift "scoliotic" curvature would be similar to true scoliotic curvature in the early stages. Anteroposterior (AP) radiographs of volunteers in neutral, in left, and right lateral translations of the thoracic cage (trunk list) were digiti...

Spinal trunk list is a common occurrence in clinical practice, but few conservative methods of spinal rehabilitation have been reported. This study is a non-randomized clinical control trial of 63 consecutive retrospective subjects undergoing spinal rehabilitation and 23 prospective volunteer controls. All subjects presented with lateral thoracic-c...

Fifty-one retrospective, consecutive patients were compared to twenty-six prospective volunteer controls in a nonrandomized clinical control trial. Both groups had chronic neck pain and lateral head translation posture. For treatment subjects, beginning and follow-up pain scales and anteroposterior (AP) cervical radiographs were obtained after 12.8...

Cervical lordosis has been shown to be an important outcome of care; however, few conservative methods of rehabilitating sagittal cervical alignment have been reported. To study whether a seated, retracted, extended, and compressed position would cause tension in the anterior cervical ligament, anterior disk, and muscle structures, and thereby rest...

There is debate concerning the repeatability of posture over time, radiograph positioning repeatability, and radiograph line drawing reliability. These ideas seem to negate the use of before-and-after spinal radiographic imaging to detect and correct vertebral subluxations. To review the results of control groups in 6 clinical control trials with b...
