Trial summary

Spinal cord stimulation (SCS) is one of the most commonly undertaken neuromodulatory surgery techniques in the treatment of neuropathic pain. The indication for SCS is an ineffective conservative treatment of chronic pain syndromes. The effectiveness of SCS in the case of neuropathic pain is high. Read more about this study

About this study

Official title: Comparison of Effectiveness of Tonic, High Frequency and Burst Spinal Cord Stimulation in Chronic Pain Syndromes: a Double-blind, Randomised, Cross-over, Placebo Controlled Trial

Spinal cord stimulation (SCS) is one of the most commonly undertaken neuromodulatory surgery techniques in the treatment of neuropathic pain. The indication for SCS is an ineffective conservative treatment of chronic pain syndromes. The effectiveness of SCS in the case of neuropathic pain is high. The positive result of SCS treatment is the reduction of previous painful symptoms by min. 50% and / or a reduction in the amount of taken analgesics and an improvement in the quality of life including sleep quality. Long-term studies estimate that in a properly selected group of patients more than 50% of patients achieve pain reduction by the required 50% and about 60% - 70% have an improvement in the quality of life and a reduction of pain.

The efficacy of SCS in different modes of stimulation is evaluated. Patients receive four different types of stimulation for 2-week period - not knowing what kind of stimulation it is. It is said that in one type of stimulation they would feel parestesias and in other three they would not. Patients are not informed that beside tonic, burst and high frequency stimulation, the fourth is an off stimulation to check for placebo effect. The test is double-blinded

Read the detailed description

Patients with FBSS and CRPS are evaluated for VAS,, dissability scale, Quality of Life (QoL), sleep disorders and mental disorders.

All patients undergo percutaneus (1 or 2) 8-contact SCS electrode implantation with trial.

All patients are blindly randomized to tonic or burst or high frequency or off stimulation. After 2-week period each participant is adequately switched to another type of stimulation for next 2 weeks. Alltogether crossover takes 8 weeks: four 2-week periods of tonic, burst, HF and off stimulation. At the end of trial period patients are subjected to the mode of stimulation which is the most efficent. The final 2-week stimulation is performed with final renewed evaluation for VAS, amount of taken medications, dissability scale, Quality of Life (QoL), sleep disorders and mental disorders. Follow-up observation will last up to 12 months.

Questions about this trial

What is this clinical trial studying?

A study testing Device: Precision Novi™ system Neurostimulation procedures in people with Failed Back Surgery Syndrome and CRPS (Complex Regional Pain Syndromes), run by Jan Biziel University Hospital No 2 in Bydgoszcz at 1 site in Poland.

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 4 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 29 May 2019. 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 Poland. 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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

Contact Pawel Sokal, Ph.D. (+48600954415, pawel.sokal@cm.umk.pl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual Analogue Scale (time frame: 12 months). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03957395, which also lists 1 linked publication.

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 29 May 2019.
