NCT03716557

Brief Summary

This study aims to investigate the clinical response to Spinal Cord Stimulation frequency parameters: 40Hz, 4000Hz and 10000Hz and explore the brain imaging changes using PET-CT scans. The response to these stimulator settings on health related quality of life will also be measured using validated questionnaires.

Outcome Measures

Primary Outcomes (1)

  • The change in patient reported back pain levels (Numerical Rating Score)

    The Numerical Rating Scale will be used to measure patient reported pain levels. The scale is from 0 (no pain) to 10 (extreme pain).

    Baseline, 4-weeks post implant, 4-weeks post randomisation, 4-weeks post crossover

Secondary Outcomes (4)

  • PET/CT Scans

    Baseline, 4-weeks post implant, 4-weeks post randomisation, 4-weeks post crossover

  • Oswestry Disability Index (ODI)

    Baseline, 4-weeks post implant, 4-weeks post randomisation, 4-weeks post crossover

  • Patients Global Impression of Change (PGIC)

    Baseline, 4-weeks post implant, 4-weeks post randomisation, 4-weeks post crossover

  • EQ-5D-5L

    Baseline, 4-weeks post implant, 4-weeks post randomisation, 4-weeks post crossover

Study Arms (3)

Spinal Cord Stimulation 4000Hz

EXPERIMENTAL

Patients will trial Spinal Cord Stimulation 4000Hz for 4 weeks. PET/CT scan will be conducted at the end of this period.

EXPERIMENTAL

Patients will trial Spinal Cord Stimulation 10,000Hz for 4 weeks. PET/CT scan will be conducted at the end of this period.

Device: Spinal Cord Stimulation 10000Hz

Spinal Cord Stimulation 40Hz

ACTIVE COMPARATOR

Patients will trial Spinal Cord Stimulation 10,000Hz for 4 weeks. PET/CT scan will be conducted at the end of this period.

Device: Spinal Cord Stimulation 40Hz

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with intractable lumbar neuropathic pain who are due to receive Percutaneous Spinal Cord Stimulation as part of their standard treatment per NICE HTA guidance 159 at Barts Health NHS Hospitals.
  • Patients between 18 and 75 years of age.
  • Patients who have given their written informed consent.
  • Female patients of childbearing potential must be using adequate contraception (i.e. using oral or IM contraception or an IUCD) and must have a negative urine pregnancy test.
  • Patients must be able to communicate in English in order to complete validated questionnaires written in English only.

You may not qualify if:

  • Patients with diabetes or any underlying neurological condition.
  • Patients known to have a condition that in the investigator's judgement precludes participation in the study.
  • Patients who have received an investigational drug or have used an investigational device in the 30 days preceding study entry.
  • Patients unable to comply with the study assessments and to complete the questionnaires.
