Pain phenotype and response to corticosteroid injection in SAPS

Official title: Association Between Pain Phenotype and Change in Pain Following Routine Corticosteroid Injection in Patients With Subacromial Pain Syndrome - A Prospective Cohort Study.

Run by Vejle Hospital · NCT07792421 · Data updated 2026-11-12

This study tests whether people with subacromial pain syndrome who have a nociplastic pain pattern respond differently to a corticosteroid injection than those without that pattern.

Is this trial a fit for you?

Likely a good fit

Adults aged 18-70 with diagnosed SAPS, experiencing shoulder pain for at least 3 months and meeting specific shoulder test criteria, who are receiving a corticosteroid injection as part of routine care.

Probably not a fit

Patients whose pain phenotype is nociplastic may not experience greater short-term relief after corticosteroid injection compared with non-nociplastic patients.

What this trial studies

This prospective cohort study examines if pain mechanism phenotype, specifically nociplastic pain, influences changes in shoulder pain after a corticosteroid injection given as part of routine care for SAPS. Participants are adults with SAPS who receive an injection and are classified by pain phenotype using IASP criteria as part of the larger NAP SAPS study. The analysis compares pain change from baseline to 4 weeks post-injection between phenotypes, aiming to understand how mechanisms of pain relate to short-term treatment response. The study is conducted at Vejle Hospital and uses standard clinical evaluations without experimental interventions beyond routine care. Findings may inform personalized approaches to managing SAPS based on pain mechanisms.

Why it matters

Potential benefit: If successful, the results could help tailor treatments for SAPS based on pain phenotype to improve short-term pain relief.

How similar studies have gone: Prior work in musculoskeletal pain shows variability in corticosteroid response, but studies focusing on nociplastic phenotypes in SAPS are emerging and results have been mixed.
