About this study
Official title: Evaluation of the Efficacy of Ultrasound-guided Cervical Root Pulsed Radiofrequency Treatment at the Intertubercular and Interscalene Levels in the Treatment of Cervical Radicular Pain
This study examines the different application techniques of ultrasound-guided pulsed radiofrequency treatment of cervical spinal nerves for cervical radicular pain.
Patients with radiologic imaging findings of C5-C6-C7 disc protrusion or extrusion, with compatible clinical and physical examinations and who have undergone ultrasound-guided spinal cervical nerve radiofrequency treatment in our clinic will be evaluated. Patients' background information will be taken in their files and missing information will be completed by phone call. Pain scores at 3 and 6 months after the procedure will be recorded by scoring from 1 to 10. Patients will not undergo any interventional procedure for research purposes.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
cervical nerve radiofrequencyProcedure or surgery
Pulsed radiofrequency treatment is applied to the cervical 5-6-7 nerve roots defined under ultrasound guidance in the intertubercular or interscalene space by approaching the cervical 5-6-7 nerve roots with an inplane technique via a cannula electrode.
| Study group | Role | What they receive |
|---|---|---|
| Interscalene cervical nerve radiofrequency | The group treated with interscalene pulsed radiofrequency intervention Receives: Procedure: cervical nerve radiofrequency | |
| Intertubercular cervical nerve radiofrequency | The group was treated with intertubercular pulsed radiofrequency intervention Receives: Procedure: cervical nerve radiofrequency |
What is being measured
The primary outcome is the main question the study is designed to answer.
Visual Analouge Scale
The Visual Analogue Scale (VAS) measures pain intensity. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be'). Ask the patient to rate their current level of pain by placing a mark on the line.
Measured: pretreatment, 3.- 6. months
Secondary outcomes (1)
Neck Disability Index
Each section is scored on a 0 to 5 rating scale, in which zero means 'No pain' and 5 means 'Worst imaginable pain'. Points summed to a total score.
Measured: pretreatment, 6. months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study examines the different application techniques of ultrasound-guided pulsed radiofrequency treatment of cervical spinal nerves for cervical radicular pain.
Patients with radiologic imaging findings of C5-C6-C7 disc protrusion or extrusion, with compatible clinical and physical examinations and who have undergone ultrasound-guided spinal cervical nerve radiofrequency treatment in our clinic will be evaluated. Patients' background information will be taken in their files and missing information will be completed by phone call. Pain scores at 3 and 6 months after the procedure will be recorded by scoring from 1 to 10. Patients will not undergo any interventional procedure for research purposes.

Questions about this trial
What is this clinical trial studying?
An observational study of Cervical Radicular Pain, run by Diskapi Teaching and Research Hospital at 1 site in Turkey (Türkiye).
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 8 Aug 2025. 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 Turkey (Türkiye). 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?
Visual Analouge Scale (time frame: pretreatment, 3.- 6. months). 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 8 Aug 2025.
