Pain Phenotype and Response to Corticosteroid Injection in Patients With Subacromial Pain Syndrome (SAPS)
Sponsor: Vejle Hospital
Summary
The goal of this prospective cohort study is to investigate whether pain phenotype is associated with subsequent change in pain intensity after corticosteroid injection given as part of routine care in patients diagnosed with SAPS. The main question it aims to answer is: Does change in shoulder pain from baseline to 4 weeks after corticosteroid injection differ between patients classified as having a nociplastic pain phenotype and those classified as having a non-nociplastic pain phenotype?

Clinical evaluation
Participants undergo a standardised clinical assessment including medical history, specific orthopedic shoulder test, diagnostic ultrasound and x-ray of the shoulder. Participants are included in this cohort only if they receive a corticosteroid injection as part of usual clinical care. The decision to administer the corticosteroid injection, is made part of usual clinical care and is independent of participation in the study. All corticosteroid injections are administered by experienced clinicians under ultrasound-guidance into the subacromial bursa.
