Design outcomes

Primary

MeasureTime frame
For patients with neuropathic pain,responder rate (30% reduction in mean pain intensity at the last visit compared to pretreatment baseline values) on the BPI scale.;For patients with migraine, Monthly frequency of headache days during weeks 9 through 12 of treatment;For patients with migraine, responder rate, who experienced a = 50% reduction in monthly headache day frequency, in the 9th to 12th week of treatment compared to the month prior to the start of the study (baseline period)

Secondary

MeasureTime frame
For patients with neuropathic pain, pain intensity (0 to 10 verbal numerical scale) after induction (day 5) and after the twelfth (12th) week of treatment, maintenance phase;For patients with neuropathic pain, number of responders (50% reduction) in the Brief Pain Inventory assessment at the end of the stimulation period (12th week), compared to baseline values;For patients with neuropathic pain, evaluation of neuropathic pain symptoms using the Neuropathic Pain Symptom Inventory (NPSI) after induction (day 5) and after the twelfth (12th) week of treatment, maintenance phase;For patients with migraine, monthly frequency of days of acute headache medication use ;For patients with migraine, HIT6 score at week 12;For patients with migraine, the Migraine Disability Assessment Test (MIDAS) score at week 12;For patients with migraine, the Migraine-Specific Quality of Life Questionnaire (MSQoL v2.1) score at week 12
