简要总结
The purpose of this investigational study is to document the safety, clinical effectiveness and health economic analytics of DTM™ SCS programming delivered through the Intellis™ neurostimulator in subjects with chronic, intractable pain of the trunk with or without lower limb pain, including unilateral or bilateral pain without prior history of spine surgery and refractory to conservative treatment and are not candidates for lumbar spinal surgery.

入选标准
- •Be a candidate for SCS system (trial and implant)
- •Have been diagnosed with chronic, refractory axial low back pain with or without lower limb pain, with a neuropathic component as assessed by the investigator, 6 months refractory to conventional therapy and are not eligible for spine surgery (e.g., lumbar fusion, discectomy, laminectomy, laminotomy) at the time of enrollment
- •Has an average back pain intensity ≥ 6.0 cm on the 10.0 cm Visual Analog Scale (VAS) at the time of enrollment
- •Be willing and capable of giving written informed consent to participate in this clinical study based on voluntary agreement after a thorough explanation of the subject's participation has been provided.
- •Be willing and capable of subjective evaluation, read and understand written questionnaires, and read, understand and sign the written inform consent
- •Be 18 years of age or older at the time of enrollment
- •Be on a stable pain medication regime, as determined by the study investigator, for at least 30 days prior to enrolling in this study
- •Be willing and able to comply with study-related requirements, procedures, and visits
排除标准
- •Had a previous spinal surgery (e.g., lumbar fusion, discectomy, laminectomy, laminotomy)
- •Has a medical, anatomical, and/or psychosocial condition that is contraindicated for commercially available Intellis™ SCS systems as determined by the Investigator
- •Has a diagnosed back condition with inflammatory causes of back pain (e.g., onset of severe pain with activity), serious spinal pathology and/or neurological disorders as determined by the Investigator
- •Be concurrently participating in another clinical study
- •Has an existing active implanted device such as a pacemaker, another SCS unit, peripheral nerve stimulator, and/or drug delivery pump, etc.
- •Has pain in other area(s) and/or medical condition requiring the regular use of significant pain medications that could interfere with accurate pain reporting, study procedures, and/or confound evaluation of study endpoints, as determined by the Investigator
- •Has mechanical spine instability as determined by the Investigator
- •Has undergone, within 30 days prior to enrollment, an interventional procedure and/or surgery to treat back and/or leg pain, which is providing significant pain relief
- •Has unresolved major issues of secondary gain (e.g., social, financial, legal), as determined by the investigator
- •Be involved in an injury claim under current litigation or has a pending or approved worker's compensation claim
- •Be pregnant (determined by urine testing unless female subject is surgically sterile or post-menopausal. If female, sexually active, and childbearing age, subject must be willing to use a reliable form of birth control.)
结局指标
主要结局
Percentage of Individual Responders
时间窗: 6 months
Individual Responders defined as decrease in back pain rating on 10 cm Visual Analog Scale (VAS) by at least 50%. Visual Analog Scale is a scaled psychometric instrument to report pain severity on a 10 cm line, with 0 indicating no pain and 10 indicating the worst pain imaginable.
次要结局
- Percentage of Individual Responders(24 months)
- Change From Baseline in Visual Analog Scale (VAS) Back Pain Score(24 months)
