Background:
Costs of health care consumption and sick leave 2006 in Sweden for Whiplash Associated Disorders (WAD) was estimated to be 4 billion Swedish crowns. Despite tremendous costs and personal sufferings there are only a few prospective randomized studies (RCT) in patients with chronic WAD, and none of them evaluating return to work, or the role of neck specific exercises with or without a combination of a behavioral approach compared with prescribed physical activity.
Aim:
The general aim of this RCT is to examine what neck-specific training with or without a combination with behavioral approach adds to prescribed physical activity of persons with chronic WAD with regard to pain intensity, physical and psychological function, health care consumption and return to work. Another aim is to study predictive factors of importance for a good outcome of rehabilitation.
Method:
After informed consent patients in age 18-63 years of age with WAD II-III with more than 6 months duration will be randomized to one out of the three alternatives of physiotherapy, treatment with medical exercise therapy with neck specific exercises (A),treatment with a behavioral approach combined with neck specific exercises (B), prescribed physical activity (C). Randomisation will be done by the central project leader. 200 patients will be included in the study. All physiotherapists engaged in the structured and well described treatment will be introduced in the program by the project leader. The measurements with good clinometric properties will be performed before treatment, after 12 weeks, 6, 12 and 24 months after inclusion into the study. Clinical measurements will be performed by a blinded investigator. Background data, disease-specific and generic data will be measured by self-evaluated answered questionnaires by the patients. Days of sick-leave will be collected from the Social Insurance Agency. Main outcomes of the measurements are pain intensity, neck specific disability and return to work. Cost-effectiveness will be calculated.

| Neck Disability Index (NDI) | NDI will be measured at baseline before intervention. Change from baseline in NDI will be measured at 3,6,12,and 24 months to investigate change over time. Baseline and change after three and six months of exercises and to investigate if a potential change of the exercises remain at 12 month and 24 month from baseline. | Baseline and change after 3 and 6 months of exercises, 3 month, 6 month, 12 month and 24 month follow-up. Change from baseline to follow-ups. Twelve month follow-up is the most important follow-up to investigate change over time from baseline. |
