Comparative StudyComparison of dynamic posteroanterior spinal stiffness to plain film radiographic images of lumbar disk height.
Assessments of spinal stiffness have become more popular in recent years as a noninvasive objective biomechanical means to evaluate the human spine. Studies investigating posteroanterior (PA) forces in spinal stiffness assessment have shown relationships to spinal level, body type, and lumbar extensor muscle activity. Such measures may be important determinants to discriminate between patients with low back pain (LBP) and asymptomatic subjects. ⋯ Computations of spinal input impedance are relatively simple to perform, can provide a noninvasive measure of the dynamic mechanical behavior of the spine, appear to have potential to discriminate pathologic changes to the spine, and warrant further study on a larger sample of normal subjects and patients.

Repeatability over time of posture, radiograph positioning, and radiograph line drawing: an analysis of six control groups.
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. ⋯ Posture, radiographic positioning, and radiographic line drawing are all very reliable/repeatable. When Chiropractic Biophysics standardized procedures are used, any pre-to-post alignment changes in treatment groups are a result of the treatment procedures applied. These results contradict common claims made by several researchers and clinicians in the indexed literature. Chiropractic radiologic education and publications should reflect the recent literature, provide more support for posture analysis, radiographic positioning, radiographic line drawing analyses, and applications of posture and radiographic procedures for measuring spinal displacement on plain radiographs.

Case ReportsChiropractic management of chronic chest pain using mechanical force, manually assisted short-lever adjusting procedures.
To discuss a case involving a patient with chronic chest pain, dyspnea, and anxiety. Although resistant to previous treatment regimens, the condition responded favorably to chiropractic manipulation of the costosternal articulations. ⋯ Certain types of chest pain may have their etiology in a subluxation complex involving the costosternal articulation. Although the possibility of myocardial involvement must be considered with all patients whose symptoms include chest pain, a musculoskeletal involvement, including costosternal subluxation complex, may be the underlying cause of the symptoms in certain patients. When this is the case, chiropractic adjustment may provide an effective mode of treatment. Further study in an academic research venue is merited to investigate the role that conservative chiropractic care can provide for patients with chest pain.
