About this study

Official title: A Prospective Randomized Controlled Study of Radio-frequency Treatment for Shoulder Impingement Syndrome

The purpose of this study is to determine whether radio-frequency (RF)-based plasma micro-tenotomy has a positive effective for the treatment of shoulder impingement syndrome with cuff tendinosis. Eighty patients with impingement syndrome and cuff tendinosis that treated arthroscopic were enrolled in the study. Patients were randomly assigned to receive either arthroscopic subacromial decompression alone (ASD group, n=40) or arthroscopic subacromial decompression combined with RF-based plasma micro-tenotomy (RF group, n=40). Clinical outcome data including VAS(Visual Analogue Scale) pain score, Shoulder range of motion (ROM), ASES(American Shoulder And Elbow Surgeons) score, UCLA(University of California, Los Angeles) score, Constant-Murley score and SST(Simple Shoulder Test) score were recorded preoperatively and at postoperative 3-week, 6-week, 3-month, 6-month and 1-year.

What participants receive

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

  • RF micro-tenotomyProcedure or surgery

    Also called RF-based plasma micro-tenotomy

    an additional bipolar RF-based device (TOPAZ, Arthrocare, Austin, TX) connected to a System2000 generator (Arthrocare, Austin, TX) was used to perform the micro-tenotomy. The device functions using a controlled plasma-mediated RF-based process (Co-ablation).The device was placed on the tendon perpendicular to its surface, for 500 milliseconds, and micro-debridement was performed at 5-mm intervals by a 2-row fashion, which covered most of the foot-print region of the supraspinatous tendon and at a depth of 3 to 5 mm

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing RF micro-tenotomy in people with Rotator Cuff Shoulder Syndrome and Allied Disorders, run by Beijing Hospital.

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 5 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 20 Mar 2012. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

VAS pain score (time frame: postoperative 3-week). 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 20 Mar 2012.
