Treatment for Frozen Shoulder using Corticosteroid Injection and Nerve Block

Official title: A Double Blinded Randomized Controlled Trial (RCT) Exploring the Additional Effect of a Suprascapular Nerve Block in Combination With an Intra-Articular Corticosteroid Injection in Patients With Frozen Shoulder

Run by Universitair Ziekenhuis Brussel · NCT06229964 · Data updated 2026-11-12

This study is testing whether a combination of a corticosteroid injection and a nerve block can help people with Frozen Shoulder feel less pain and move their shoulder better compared to a fake treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are Dutch or French speaking adults aged 18 and older who have been diagnosed with Frozen Shoulder lasting more than one month.

Probably not a fit

Patients with posttraumatic or postsurgical shoulder stiffness, or those with certain medical conditions affecting the shoulder, may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate the effectiveness of a glenohumeral intra-articular corticosteroid injection combined with a suprascapular nerve block compared to a sham nerve block in patients suffering from Frozen Shoulder. The study will measure outcomes such as shoulder-related disability, pain, and stiffness through a double-blinded randomized approach. Participants will be monitored for improvements in pain and function, with a focus on shared decision-making and patient education regarding their treatment options.

Why it matters

Potential benefit: If successful, this treatment could significantly improve pain relief and functional mobility for patients with Frozen Shoulder.

How similar studies have gone: Previous studies have shown promise with similar approaches, but this specific combination of treatments in a double-blinded format is relatively novel.
