- Primary Outcome Measures
Name Time Method Analgesic efficacy 40 minutes Analgesic efficacy will be assessed from several endpoints. The primary endpoint will be defined as the change of pain level between baseline (T0) and 40 minutes (T1) after baseline. The pain level will be assessed using a self-administered numeric pain intensity scale (NPIS), ranged from 0 (no pain) to 10 (worst pain possible). A minimal 30% decrease of pain level between baseline and T1 will define the success, and other cases will define the failure of the treatment.
- Secondary Outcome Measures
Name Time Method intensity of the pain neuropathic 120 minutes the intensity of the pain neuropathic component using the Neuropathic Pain Symptom Inventory (NPSI) at T4, T5, and T6 {Bouhassira, 2004 #9}; the NPSI is a 12-item self-administered questionnaire describing the intensity of the symptoms associated with pain neuropathic
