About this study

Official title: Pulsed Radiofrequency in Treatment of Classic Trigeminal Neuralgia (Prolonged Duration Versus Higher Voltage)

The current study investigated the efficacy of pulsed radiofrequency in pain reduction in TN patients and compared the efficacy and the impact on the quality of life of the standard technique with a prolonged duration technique and a higher voltage one.

Entire enrolled patients were diagnosed as classic TN according to the international headache society classification (IHS, 2013) and underwent brain MRI and MRA to exclude secondary causes. Patients were randomly divided into three groups, Group A patients underwent PRF using the standard settings, group B patients underwent PRF with prolonged duration and Group C patients underwent PRF with higher voltage. VAS and pain amplitude reduction were recorded before the intervention and 1 hour, 1 day, 1week, 1 month, 6 months and 1year after it. Quality of life was assessed before and 1 year after the intervention.

Study groupRoleWhat they receive
Group AActive comparatorusing the standard settings of pulsed radiofrequency technique (PRFT). two cycles, each one for 2 minutes at 45 Volts (V) with a pulse width of 10 milliseconds (ms) and a pulse frequency of 4 Hertz (Hz). The cut-off needle tip temperature is set at 420 Celsius (C).
Receives: Procedure: pulsed radiofrequency
Group BExperimentalusing prolonged duration of PRFT. four cycles, each one for 2 minutes at 45V with a pulse width of 10ms and a pulse frequency of 4Hz. The cut-off needle tip temperature is set at 420C.
Receives: Procedure: pulsed radiofrequency
Group CExperimentalusing higher voltage PRFT.. two cycles, each one for 2 minutes at 60V with a pulse width of 10ms and a pulse frequency of 4Hz. The cut-off needle tip temperature is set at 420C.
Receives: Procedure: pulsed radiofrequency

Questions about this trial

What is this clinical trial studying?

A study testing pulsed radiofrequency in people with Trigeminal Neuralgia, run by Mansoura University.

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 3 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 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

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?

Pain amplitude reduction (time frame: 1 year). 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 Apr 2020.
