Background: Subacromial Impingement Syndrome (SIS) is a leading cause of shoulder pain and disability, especially among adults over 40 years old. Subacromial injections are frequently recommended when physiotherapy and pain relief are ineffective. Despite the common use of corticosteroids along with local anaesthetics like mepivacaine, proof of their effectiveness over anaesthetic used alone is still inconsistent. Objectives: To determine whether subacromial injection with mepivacaine (1%) plus saline is non- inferior to mepivacaine (1%) plus triamcinolone acetonide (40 mg) in improving shoulder pain and function after 6 weeks of follow-up in patients aged 40 years or older with subacromial impingement syndrome. Additional outcomes assessed at baseline, at 6 and 12 weeks include pain levels (VAS), range of motion (ROM), compliance with home exercises and use of pain medications. Methods: A randomized, triple-blind, non-inferiority clinical trial will be carried out at Hospital Universitari Dr. Josep Trueta (Girona, Spain). Eligible patients will be recruited consecutively and randomly allocated to either the corticosteroid or control group. All injections will be ultrasound-guided and performed by experienced physicians. Outcomes will be evaluated at baseline, 6, and 12 weeks by blinded evaluators
