What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.

Spinal cord stimulator is switched off for 12 hours
SCS is switched onDevice

| Study group | Role | What they receive |
|---|---|---|
| SCS off | Experimental | Not described Receives: Device: SCS is switched off |
| SCS on | Experimental | Not described Receives: Device: SCS is switched on |
What is being measured
The primary outcome is the main question the study is designed to answer.
Exhaled breath changes
The investigators will examine the difference in exhaled breath patterns between both measurements (SCS on versus SCS off), measured with the Aeonose.
Measured: Two times on the same day; once while SCS is switched off and once while SCS is switched on. Total study duration lasts one day.
Secondary outcomes (1)
Pain intensity scores using the Visual Analogue Scale
Pain intensity score on that time on a Visual Analogue Scale (VAS) ranging from zero (no pain) towards 10 (worst possible pain) for the pain intensity.
Measured: Two times on the same day; once while SCS is switched off and once while SCS is switched on. Total study duration lasts one day.

Questions about this trial
What is this clinical trial studying?
A study testing SCS is switched off and SCS is switched on in people with Failed Back Surgery Syndrome, run by Universitair Ziekenhuis Brussel at 1 site in Belgium.
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 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 May 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Exhaled breath changes (time frame: Two times on the same day; once while SCS is switched off and once while SCS is switched on. Total study duration lasts one day.). 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 21 May 2021.
