Intra-articular corticosteroid,
does it really help with Short-term improvement in pain and shoulder function in adhesive capsulitis?
research showsIntra-articular corticosteroid is rated C despite improving early pain and function in adhesive capsulitis. Carette randomized 93 and analyzed all 93 by intention to treat with last observation carried forward; the six-week SPADI primary endpoint succeeded at P=.0004. An approximately 27.6-point contrast exceeded the 8-to-13-point SPADI MCID range summarized by Roy 2009, but a sample below 200 and a six-week primary assessment create a B2 ceiling.

Useful facts when choosing a product
- Carette used one fluoroscopically guided intra-articular 40-mg triamcinolone hexacetonide injection.
- Groups converged by twelve months.
What the research actually shows
Carette randomized 93 participants across four groups and included all 93 in intention-to-treat analysis using last observation carried forward. The six-week SPADI primary assessment succeeded at P=.0004. Funding came from the nonindustry Arthritis Society of Canada. A 2017 meta-analysis of five studies and 225 participants found pain reduction at zero to eight weeks but no difference at nine to twenty-four weeks. Roy 2009 summarized a SPADI MCID range of 8 to 13 points. Verdict 1678, which is D with 28 points, concerns repeated knee injections, while verdict 1577, which is F with 18 points, concerns knee hyaluronic acid; both differ in joint or intervention.
Why this is classified as C (58)
P, R2, I2, and E+ are capped by B2 for small size and a six-week primary assessment, giving C with 58 points.
Counterpoint. It may create a short window for rehabilitation when early pain limits exercise.
Rejudgment record. Cross-check applied — Clinically important short-term symptom benefit capped by small size and short duration
| Endpoint | P | Patient-reported treatment goal - the symptom is the goal |
| Replication | R2 | Independently replicated across trials |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
The scoring table and the verdict agree (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Pain reduction through eight weeks | C | Pooled benefit is positive but short term. |
| Short-term shoulder function improvement | C | The six-week SPADI effect exceeded MCID. |
| Durable long-term pain and function improvement | D | Pain was null at nine to twenty-four weeks and groups converged at twelve months. |
