A Prospective, Open Label, Pilot Study of Patient OutcoMes Following Successful TriAl of High Frequency SpInal CorD Stimulation at 10kHz (HF10™) Leading to Permanent Implant Compared to Trial Failure and Standard CarE for the TreatmeNt of Persistent Low BACK Pain of Neuropathic Origin

Inclusion Criteria: I. Patient is 18 years of age or older and has given written informed consent. II. Has persistent chronic predominant low back pain of neuropathic origin, with or with out radiculopathy, for a minimum of 6 months III. Visual Analogue Scale (VAS) back pain score of at least 50 mm at baseline IV. Confirmation of pain from neuropathic origin by SLANSS score (≥12) AND PainDETECT score( ≥19) V. Total daily dose of opioids equivalent to ≤200mg of Morphine VI. No previous open spinal surgery (percutaneous procedures such as nucleoplasty are not considered as open surgical procedures) VII. Failed conservative therapies such as physiotherapy, chiropractor, hydrotherapy, TENS. VIII. MRI within the previous 18 months (as per standard care) IX. In the investigators opinion the patient is a suitable candidate for HF10 Exclusion Criteria: I. Patient has mechanical spine instability based on flexion/extension testing of lumbar spine (documented in the last 6 months) II. Patient is pregnant, or pregnancy is suspected or planned within the first six months of the study timeframe. III. Patient has a cardiac pacemaker, automatic defibrillator, or any other implanted device, which will make the trial impossible. IV. Allergy to device components or drugs to be used in the intended procedure. V. Medical co-morbidities that preclude surgical intervention. VI. Patient is incapable of understanding or responding to the study questionnaires VII. Patient is incapable of understanding or operating the patient programmer handset. VIII. History of previous open spinal surgery (not percutaneous procedures) IX. Patient is morbidly obese (BMI ≥ 40). X. Patient is simultaneously participating in another device or drug study within the last 30 days. XI. Patient has a spinal fracture, tumour or infection. XII. Clinical evidence of cauda equina syndrome. XIII. Progressive neurologic deficit.
