And Now for some news ….

Spinal Manipulation for Lower Extremity Injuries

A study in the September 2006 issue of Chiropractic and Osteopathy looked at Lumbar disc herniation being a problem frequently encountered in manual medicine.

While manual therapy has shown reasonable success in symptomatic management of these cases, little information is known how manual therapy may affect the structure and function of the lumbar disc itself.

In cases where lumbar disc herniation is accompanied by radicular symptoms, electrodiagnostic testing has been used to provide objective clinical information on nerve function.

The study presented examines the treatment rendered for a patient with lower extremity neurological deficit, as diagnosed on electrodiagnostic testing. The patient was treated using spinal manipulation and exercises performed on a Pettibon Wobble Chairtrade mark, using electrodiagnostic testing as the primary outcome assessment.

The study concluded that - Motion-based therapies, as part of a comprehensive rehabilitation program, may contribute to the restoration of daily function and the reversal of neurological insult as detected by electrodiagnostic testing. Electrodiagnostic testing may be a useful clinical tool to evaluate the progress of chiropractic patients with lumbar disc herniation and radicular pain syndromes.

Exercise and Colon Health

Two studies published in the Journal of Clinical Oncology demonstrate that moderate amounts of exercise completed in the 6-12 month period post-therapy, can improve overall survival rates for colon cancer survivors.

The improvements were observed in patients with both early onset and more advanced colon cancer, all of who underwent surgical procedures intended to cure the disease. Those individuals completing the 6-12 month exercise program had approximately a 50% higher survival rate than their less active counterparts.

From previous studies it is known that regular physical activity reduces the risk of developing colon cancer, but until now few studies have looked at the survival effect of exercise on people who have been treated for disease.

Two studies utilized two different sets of data to arrive at the same conclusion. One study examined 832 patients with Stage III colon cancer who had undergone surgery and chemotherapy.

The participants reported their levels of recreational physical activity and health status six months after therapy was completed.

Researchers determined that individuals who exercised at a moderate intensity (walking six or more hours per week at an average pace of 2.0- 2.9 mph ) increased their likelihood of survival by 47%.

The second study followed 573 patients who had undergone therapy to cure Stage I to Stage III colon cancer. The data indicated that individuals who increased their level of physical activity above the pre-diagnosis level were 50% more likely to remain free from disease than those who remained physically inactive.

As always, COT’s HealthBeat recommends discussing any exercise questions or modifications with a qualified healthcare provider.

Differences in Force between Various Manipulation Delivery Techniques

A study in the October issue of the Journal of Manipulative and Physiological Therapeutics, JMPT, looked at the variation of manipulative forces produced by instruments and a manual technique.

The study concluded that force-producing instruments reduce absolute variation in force magnitude and duration. However, this reduction does not eliminate significant differences in absolute force parameters observed to occur between some operators using the same instrument.

Given these observations, claims of instrument superiority that do not account for interoperator variability should be considered with caution.

Manipulation and Heart Rate

Another study in the October JMPT looked at whether there was a way to measure the effects of thoracic spinal manipulation on heart rate variability (HRV) in a cohort of healthy young adults.

Results of the study found that in healthy young adults, thoracic spinal manipulation was associated with changes in HRV that were not duplicated by the sham procedure

The study concluded that high-velocity and low-amplitude manipulation of the thoracic spine appears to be able to influence autonomic output to the heart in ways that are not duplicated by a sham procedure or by other forms of somatic/physical therapies.
