Description of intervention(s) / exposure
The study is a RCT with unblinded treatment and blinded outcome assessment in patients with acute whiplash disorders, classified as WAD II, to test the effectiveness of a pragmatic multi-professional management approach (medical, physiotherapy and psychological management) to reduce the incidence of chronicity. Within the randomization process, subjects will be stratified on three factors predictive of a poor prognosis (high NDI score; signs of moderate post-traumatic distress reaction; abnormal sensory responses {at least two of cold hyperalgesia, pressure hyperalgesia, impaired sympathetic vasoconstriction}) to ensure equal distribution of these factors between the pragmatic intervention and usual care groups. The pragmatic management approach will be tested against a control intervention of usual care. The medical, physiotherapy and psychological management within the pragmatic approach will be prescribed in accordance with the subjects level of pain and presenting physical and psychological features. The intervention period and the number of medical, physiotherapy and/or psychological consultations will be variable and as required for the individual subject depending on the severity of their condition, but will be for a maximum of 10 weeks. Full recovery can be expected for at least 40% of whiplash patients within 12-24 weeks post-injury with usual care. Outcomes will be tested after the 10 week intervention period (week 11) regardless of the length of treatment time, and at 6 months and 12 months post-injury. The direct costs of this approach and of usual care will be measured and the costs associated with lost earnings and time in treatment will be calculated until 12 months post-injury. The treatment costs will be those incurred during the intervention period as well as any further treatment costs incurred in the 12 months post-injury. In addition to these measures of costs, utility weights (or health state preferences) will be measured using the standard gamble (SG), time-trade-off (TTO) and visual analogue scale (VAS) approaches.

Outcomes
Primary outcome [1] 263 0
1.The Neck Disability Index (NDI) is a validated questionnaire which measures patients' self rated neck pain and disability. It will be used to calculate the proportion of subjects reporting recovery, defined as NDI score <8.
Timepoint [1] 263 0
At 6 months.
Primary outcome [2] 264 0
2. Utility weights/health preference data derived from the SG, TTO and VAS approaches. These methods have commonly been employed to create Quality-Adjusted Life-Years (QALYs) for the purposes of cost-utility analysis (CUA).

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation process will be conducted by an independent body, the Clinical Trials Centre in the School of Population Health, UQ, on receipt of a phone call from the trial RA.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation process is using an ACCESS database structure with both customised programming and tested inbuilt function written in MS Visual Basic. We are using the minimisation technique with three stratification factors. Subjects will be stratified according to psychophysical measures indicative of a poor prognosis (values derived from confidence intervals of control subjects, except for the NDI and IES scores which are standard values of at least moderate dysfunction). Based on our regression analysis, we will regard initial NDI as the primary factor (F1), signs of severe post-traumatic distress reaction (IES) as the second factor (F2), and abnormal sensory responses as the third factor (F3). The third factor will be at least 2 of; elevated cold pain thresholds over the cervical region, lowered pressure pain thresholds over the tibialis anterior muscle (TA), impaired sympathetic vasoconstriction. The values for abnormal responses represent those outside the values for normative data. Subjects will be stratified prior to randomisation using the following values:
