Repositioning error of the trunk was tested in 20 subjects with chronic low back pain and in 20 control subjects. The 3Space Tracker (Polhemus, Colchester, VT), a device that measures three-dimensional position in space, was used to determine the subject's trunk position. ⋯ Because proprioception is complex and entails the use of many afferent receptors, it is difficult to measure any one afferent deficiency discretely. The authors believe that this study, in which one aspect of proprioception was measured in an indirect manner, provides important background information on low back position sense. Further studies analyzing aspects of proprioception in subjects with low back pain are recommended.

Randomized Controlled Trial Clinical Trial
Coordination of primary health care for back pain. A randomized controlled trial.
A randomized controlled trial comparing usual care with a program for the coordination of primary health care (CORE) for the treatment of subacute low-back pain patients. ⋯ The therapeutic results for workers with low-back pain could be improved by implementing the clinical practice guidelines with primary care physicians in a large community, without delaying the return to work. The CORE intervention for back pain patients is highly relevant to primary care practice. It is simple in its application, flexible to accommodate physicians' and- patients' preferences in health care, and it is effective on patients' clinical outcome.

A descriptive case series pre- and post-treatment design, including a 6-month follow-up. ⋯ These early results indicate that a multimodal treatment program has the potential to be an effective treatment for patients with chronic symptoms after a whiplash injury of the neck--a group of patients who have in the past been considered intractable or, at the very least, puzzling.

Four cadavers had cervical foraminotomies performed at noncontiguous levels using either the standard open technique or the microendoscopic technique. ⋯ Posterior cervical foraminotomy, using the microendoscopic technique, is technically feasible and may be applicable to the treatment of foraminal stenosis and laterally located cervical disc herniation. Studies in live animals are currently examining techniques for hemostasis.
