Descriptive Information
Brief Title  ICMJE Randomized WAD Study
Official Title  ICMJE Treating Selected Chronic WAD Patients: Cervical Fusion or Multidimensional Rehabilitation. A Randomized Study
Brief Summary

Background: The majority of patients suffering a whiplash injury (WAD) will recover, but some may have symptoms for years despite all kinds of conservative treatment. The Neck Pain Task Force (2008) found no existing evidence for positive effects of fusion operations in such patients. Some of them, however, present with symptoms that might indicate pain from a motion segment, possibly the disc. Our aim was therefore to test this possibility by performing a randomized study comparing cervical fusion and multimodal rehabilitation in chronic WAD patients.

Methods: Patients with a specified symptomatology, all with pronounced symptoms for long periods of time, were recruited and randomized to surgery (25 pat.) or to multimodal rehabilitation (24 pat.). All patients were investigated before start of the study and at follow-up approximately two years after treatment by four independent examiners from disciplines usually involved in treating WAD patients. The patients also gave their own assessments of the treatment results. Seven patients in each group did not undergo the allocated treatment for various reasons.

Detailed Description


representing different disciplines: neurology, orthopedics, physical medicine and psychology. Each patient´s perceived change in outcome was also assessed. Assessment was made before treatment and at follow-up two years afterwards.

In addition to the assessments of outcome made by the examiners, the patients completed the SF-36, EQ-5D and BIS (Balanced Inventory for Spinal Disorders) questionnaires before treatment and at follow-up. The results of these assessments will be given in a forthcoming paper.

6b. No changes in trial outcomes were made during the study.
