NCT02774694

Brief Summary

Interventional pain management for back and neck pain is widely used, but the indications and relative merits of these techniques rest subject to discussion. This study aims to identify prognostic criteria for patients who might specifically benefit from interventional pain management. Specifically, the nociceptive reflex threshold will be investigated, which is a measure of central sensibilisation and thus a potentially important prognostic factor.

Outcome Measures

Primary Outcomes (1)

  • ROC-AUC for incidence of pain reduction>30% at 1 week

    Primary study outcome is the diagnostic accuracy of the NFR threshold, measured as area under the "receiver operating characteristic ROC" curve, for the following main pain management outcome: "pain reduction of 30% one week after the interventional procedure

    1 week

Secondary Outcomes (8)

  • ROC-AUC for incidence of pain reduction>30% at 1 month

    1 month

  • ROC-AUC for incidence of pain reduction>30% at 3 months

    3 months

  • ROC-AUC for incidence of pain reduction>30% at 6 months

    6 months

  • ROC-AUC for physical functioning at 1 week

    1 week

  • ROC-AUC for emotional functioning at 1 week

    1 week

  • +3 more secondary outcomes
