Outcome Measures

Primary Outcomes (1)

  • response to PRF

    loss of neuropathic pain, lasting at least 6 months was defined as a positive categorical outcome. Neuropathic pain was assessed with Douleur Neuropathique 4 questionnaire (DN4) at baseline, and at 1., 3, 6 months by the pain specialist authors. DN4 consisted of 10 items. The first seven items were associated with the patients' subjective compliants related to pain and sensational variations while the last three items were associated with the clinical findings. Those patients who had a score ≥ 4were considered to have neuropathic pain. Patients with a positive outcome at the 1 or 3 month follow-up,but did not come again were excluded from the study. After the data collection, the patients wer divided into two groups: responders with a positive outcome and nonresponders with a negative outcome.MP for 6 months. Age, sex, body mass index (BMI), employment, tight clothing, belts, carrying things at the back of pants were asked in detail at the initial visit of the Pain Clinic.
