Chiropractic Prone Distraction for Lower Back Pain

Summary

Back pain is a major cause of disability in the United States. The lifetime prevalence of low back pain is estimated at 60-90%. Back pain has conservatively been estimated to involve total direct and indirect costs of over $25 billion annually in lost wages, treatment, and related issues. These losses clearly extend to the active duty population cared for by military health care facilities.

Chiropractic medicine is characterized by the use of a number of physical manipulations and mobilization techniques, which can be used singly or in combination to treat a variety of medical conditions. Although basic clinical practice guidelines for Chiropractic have been developed, few studies have rigorously compared techniques and their outcomes for specific conditions. Fewer still have sought to correlate treatment modality with both anatomical effect and clinical outcome.

Throughout the military, Chiropractic care is available only to active duty personnel and only at a limited number of medical treatment facilities. At National Naval Medical Center, it is a well-established treatment option, where the full array of techniques is employed, primarily for painful conditions, and most often for back pain. This study seeks to clarify the mechanisms of action and efficacy of one specific treatment option, prone distraction, for the relief of subacute sciatica due to radiographically confirmed herniated disc, and to compare it to side-posture manipulation and standard medical management.

Prone lumbar distraction utilizes a specialized table with motorized continual motion distraction. This table has multiple mechanical articulations that can be used to place patients in a wide variety of positions. Patients being treated with continuous motion distraction are placed prone with the table positioned for maximum comfort and centralization of symptoms.

Side posture manipulation is a widely practiced, standard chiropractic technique, which has been shown to provide considerable clinical improvement for patients with sciatica. Low- grade oscillatory stresses are performed within the physiological range of normal joint motion. The hip, pelvis and lumbar spine are rotated forward with manual pressure while a counter rotation of the chest and thoracic spine is applied.
