Brief Summary:
This a single center study comparing two forms of electrical stimulation: sub-sensory burst stimulation (DRG-Burst3D) and standard low frequency stimulation (DRG-LF) in the dorsal root ganglion of subjects diagnosed with neuropathic pain
Detailed Description:
The study will consist of two phases; a 26 day randomized trial phase in which the subject will assess the effectiveness of DRG-Burst3D and DRG-LF, and a 12 month post permanent implant follow up phase.
The randomized trial phase which consists of two phases Trial Assessment 1 and Trial Assessment 2 will last for a maximum of 26 days. Subjects will be randomized 1:1 to receiver 10 ±3 days of DRG-LF stimulation and 10 ±3 days of Burst3D stimulation (DRG-Burst3D) to assess the efficacy of each the different forms of stimulation throughout the trial phase.
Subject will complete in clinic questionnaires (SF-36, ODI, DN4, PGIC, Paraesthesia Map) during the trial phase along with multi-day diary to record VAS pain scores. The subject-reported data from multi day diary and in-clinic assessments will be the basis of verification for success of trial (\> 50% overall pain relief). Following device trial subjects will take a questionnaire on program preferences of DRG-LF or Burst3D.
If VAS score during either of the two trial assessments is reduced by at least 50% compared to the baseline score, the subject will be considered for permanent DRG-SCS implant. Subjects who do not experience a \>50% overall pain relief on either of the two stimulation settings will exit the study.
Subject who underwent a successful trial (\> 50% overall pain relief) will then be implanted with Boston scientific Precision NoviTM neurostimulator trial System. Post permanent implant subjects will receive both DRG-LF and Burst3D programs and use their preferred stimulation program.
The subjects will then be followed for 12 months to assess the long-term treatment outcome. Follow up visits will occur at 1, 3, 6 and 12 months after permanent implant. During each of these visits subjects will rate their pain using the VAS, their quality of life using the EQ-5D, their disability using the ODI, Neuropathic pain using DN4 , Mental health using SF-36 and sensation using paraesthesia Map.
