- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. Provides written Patient Informed Consent/Patient Information Sheet prior to study-related activities being conducted~2. ≥ 18 years of age at time of informed consent~3. Willing and available to attend visits as scheduled and to comply with the study protocol~4. Willing and able to undergo assessments as part of the evaluation for eligibility and endpoints~5. Willing and able to use the external neurostimulator, recharging equipment (if applicable), and patient programmer per the schedule required by the protocol~6. Diagnosed with FBSS (i.e.):~   * Has had persistent pain for 6 months following most recent anatomically correct, successful surgery AND~  * There are no further therapeutic surgical options available as assessed by appropriate investigation~7. Back pain is considered intractable and has been adequately treated (failed an appropriate trial of at least 3 different classes of back pain treatments (pharmaceutical and/or non-pharmaceutical))~8. Is an appropriate implant candidate for the SQS system~Exclusion Criteria:~1. Has been or is currently being treated with spinal cord stimulation, subcutaneous nerve stimulation, peripheral nerve stimulation or an implantable intrathecal drug delivery system~2. Evidence of an active disruptive psychiatric disorder that is significant enough to impact the perception of pain, compliance to intervention and/or ability to evaluate treatment outcome, as determined by the investigator~3. Has a pain condition unrelated to FBSS that is severe enough to overshadow the FBSS pain in the opinion of the investigator~4. Spinal instability or anatomic compression that requires further surgery~5. Spinal fusion at more than 3 vertebral levels~6. Currently enrolled in or plans to enroll in any concurrent drug and/or device study that may confound the results of this study~7. Allergic or has shown hypersensitivity to any materials of the device system which come in contact with the body~8. History of coagulation disorder or lupus erythematosus~9. Involved in current litigation regarding back pain
