Brief Summary

Early screening of posttraumatic neck pain after accidents \- A clinical prediction tool with biomarkers predicting chronic posttraumatic neck pain. The goal of this prospective cohort study is to develop a clinical prediction tool with biomarkers for early prediction of chronic posttraumatic neck pain. Aims:

  1. 1.validate and further develop an existing prediction and screening tool for post traumatic neck pain using biomarkers for stress (i.e. HRV). The investigators hypothesize that the addition of a HRV to the existing screening and prediction tool in the acute phase (i.e. \< 72 hours) post-accident can contribute to better and earlier identification of high-risk patients who continue to experience moderate to high degree of impairment after 12 months (i.e. NDI \>32%).
  2. 2.examine whether the health economic costs for the group that does not improve are greater after 12 months. The investigators hypothesize that the health economic costs for the group that does not improve are greater after 12 months (labour market attachment and health services) compared to those who improve (NDI score \< 10% vs. \> 32%).
  3. 3.evaluate the role of low HRV on the development of PTSD 3 month after the accident. the hypothesis is that low HRV is a predictor of the development of PTSD.3 month after an accident.
  4. 4.Evaluate whether PTSD mediates the association between low HRV and pain sensitization 3 months after the accident. The investigators hypothesize that the development of pain sensitivity 3 month after an accident is associated with low HRV and PTSD.
