  • Documented history of trunk and/or limb pain of at least 180 days
  • Average back pain intensity of 5 or greater on a 0-10 numerical rating scale during the 7-day period prior to the Screening Visit
  • Pass study site's routine psychological/psychiatric evaluation within 180 days of the Trial Lead Insertion Visit
  • If taking any medications for chronic pain, must be on a stable prescription during the 14-day period prior to the Trial Lead Insertion Visit and agree to continue on the same prescription throughout study participation
  • Subject is willing and able to comply with all protocol-required procedures and assessments/evaluations
  • Subject is able to independently read and complete all questionnaires and/or assessments provided in English
  • 18 years of age or older when written informed consent is obtained
  • Subject signs a valid, Ethics Committee-approved informed consent form (ICF) provided in English

Exclusion Criteria:

  • Unable to operate the PrecisionPlus™ system
  • Primary source of pain is cancer-related, pelvic, visceral, angina, or migraine
  • Is a high surgical risk
  • Is diabetic
  • Is immunocompromised
  • Currently on any anticoagulant medications that cannot be discontinued during perioperative period
  • Untreated major depression or untreated generalized anxiety disorder
  • Diagnosed with somatoform disorder, severe personality disorder, borderline personality disorder
  • Diagnosed with any major psychiatric disorder not specifically listed in previous two exclusion criterion
  • Currently diagnosed with cognitive impairment that would limit subject's ability to discern differences in pain severity, complete a pain diary, perform wound care
