What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of pain relief experienced in the area of pain identified at baseline compared to 12 months post full implant of the Freedom SCS system.

    Self reported pain intensity measured by the Visual Analog Scale (VAS)

    Measured: 12 months

  2. Incidence and severity of device related adverse events during the study.

    Measured: Up to 12 months

Secondary outcomes (11)
  1. To assess compliance data to indicate usability of the device.

    Questionnaire

    Measured: 12 Months

  2. To assess the implanters' experience with the device.

    Questionnaire

    Measured: Average of 7 days after implant

  3. Patient satisfaction with treatment.

    Questionnaire

    Measured: 12 Months

  4. Reduced visits to health care institutes for chronic back and leg pain.

    Questionnaire

    Measured: 12 Months

  5. Improved work status.

    Questionnaire

    Measured: 12 Months

  6. Improved quality of life function via the ODI and EQ-5D questionnaires

    ODI and EQ-5D Questionnaires

    Measured: 12 Months

  7. Reduction in use of analgesics

    Measured: 12 Months

  8. Reduced operating theater time

    Review of hospital records

    Measured: Average of 7 days after implant

  9. Reduced skin to skin time

    Review of hospital records

    Measured: Average of 7 days after implant

  10. Reduced skin to fluoroscope time

    Review of hospital records

    Measured: Average of 7 days after implant

  11. To monitor non-device and non-SCS-related adverse events

    Measured: Up to 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Freedom Spinal Cord Stimulator System in people with Chronic Low Back Pain and Pain in Leg, Unspecified, run by Curonix LLC at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Are results available for this study?

The study was stopped early (reason given: Lack of recruitment). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of pain relief experienced in the area of pain identified at baseline compared to 12 months post full implant of the Freedom SCS system. (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Oct 2020.
