Don’t sit up straight

The longstanding advice to “sit up straight” has been turned on its head by a new study that suggests leaning back is a much better posture.

Researchers analyzed different postures and concluded that the strain of sitting upright for long hours is a perpetrator of chronic back problems.

Using a new form of magnetic resonance imaging (MRI), researchers studied 22 volunteers with no back pain history. The subjects assumed three different positions: slouching; sitting up straight at 90 degrees; and sitting back with a 135-degree posture—all while their spines were scanned. (more…)

Smokers and the obese cheaper to care for, study shows

Preventing obesity and smoking can save lives, but it does not save money, according to a new report.

It costs more to care for healthy people who live years longer, according to a Dutch study that counters the common perception that preventing obesity would save governments millions of dollars.

“It was a small surprise,” said Pieter van Baal, an economist at the National Institute for Public Health and the Environment in the Netherlands, who led the study. “But it also makes sense. If you live longer, then you cost the health system more.”

In a paper published online Monday in the Public Library of Science Medicine journal, Dutch researchers found that the health costs of thin and healthy people in adulthood are more expensive than those of either fat people or smokers. (more…)

Our understanding of the biomechanics and neurology of the subluxation continues to evolve as more research is published which helps explain the nature of this lesion. Historically, the subluxation has been at the heart of the identity and purpose of the chiropractic profession.

Contemporary models provide new insights into this elusive and sometimes mysterious problem which we attempt to find by various clinical means and correct by the application of high-velocity, low-amplitude thrusts. Let’s review past models, but focus primarily on the latest evidence concerning the subluxation published in the recent scientific literature in order to improve our understanding, insight, and application of clinical interventions to improve patient outcomes with chiropractic care.

Older Models of Subluxation: Static Malposition and Pathology

Over the 115-year history of chiropractic, there have been many varied attempts to explain and clarify the subluxation. In the past, descriptions of this lesion were phrased in pathological terms and often included malposition, distortion of the intervertebral foramen and impingement of nerves as primary components. Henderson, et al., [1] described early notions of subluxation as static mechanical lesions, a misalignment or a bone out of place, as seen on a neutral radiograph. The authors explain that this static model has been vigorously challenged in the scientific literature.

Lantz [2] raised concerns about the strictly static, structural interpretation of vertebral subluxation and introduced his own hierarchical model including kinesiopathology, neuropathology, myopathology, connective tissue pathology, vascular abnormalities, as well as inflammatory response, histopathology, and biochemical abnormalities. Similarly, Dishman [3] described the vertebral subluxation complex in terms of various pathologies including neuropathology, myopathology, kinesiopathology, histopathology, and biochemical abnormalities.
