What is the STIFF Trial?
The STIFF Trial (Steroid vs. PRP Injections for Frozen Shoulder) is a randomized controlled trial (RCT) investigating whether platelet-rich plasma (PRP) or corticosteroid injections provide better pain relief and mobility improvement for Frozen Shoulder (Adhesive Capsulitis).
✔ Free participation for eligible patients.
✔ Goal: Compare the effectiveness of PRP vs. Cortisone in reducing pain and restoring shoulder function.
✔ Duration: Recruiting 200 patients over 12 months.
Who Can Participate?
You may be eligible if you have:
✅ Painful shoulder stiffness with restricted movement.
✅ Loss of external rotation (common in Frozen Shoulder).
✅ Normal shoulder X-ray (no fractures or arthritis).
🔎 Doctors & Referrers: If your patient meets these criteria, we welcome referrals!
Why This Trial is Important
🔹 PRP and cortisone injections are commonly used, but strong comparative evidence is lacking.
🔹 PRP may promote healing, while cortisone reduces inflammation, and we aim to determine which is superior for Frozen Shoulder.
🔹 This study will provide evidence-based guidance for the best treatment approach.
How is Frozen Shoulder Treated?
Frozen Shoulder is a condition where shoulder movement becomes painful and restricted due to inflammation and stiffness.
Current treatment options include:
💉 Corticosteroid Injections – Reduces inflammation and pain.
🩸 Platelet-Rich Plasma (PRP) Injections – Stimulates natural healing and tissue repair.
🏋️ Physiotherapy & Stretching – Helps restore mobility over time.
🔬 Hydrodilatation & Surgery – Used for severe or prolonged cases.
Our trial compares PRP vs. Cortisone to determine the most effective option for Frozen Shoulder.
