Case Report: Focused shockwave therapy (fESWT) in thumb carpometacarpal joint osteoarthritis: a single case study.
Timmy Gustafsson, Sofia Ryman Augustsson
PMID 41602581WHAT IT FOUND
In one woman with thumb osteoarthritis, focused shockwave therapy was followed by less pain, better grip and lower disability over a year.
This is a single case, so it cannot show the treatment works.
Key findings
01The patient reported less pain and better gripping, pinching and carrying after treatment.
02Grip strength and QuickDASH disability improved at follow-up.
03The patient tolerated the sessions, with discomfort decreasing and no redness or bruising.

What it does not show
This is one patient, so it cannot show what fESWT does in other people. There was no control group, so placebo, natural variation, or other factors cannot be ruled out. The patient had already tried conservative treatments, so the case does not show how fESWT compares with them. No imaging was used to check tissue changes, so the mechanism cannot be confirmed. Case reports tend to publish positive outcomes, so negative or neutral responses may be missing. Patient-reported outcomes may be affected by recall bias during follow-up.
Declared interests
The authors state financial support was received for the work or publication, and open-access funding was provided by Linnaeus University.
The easy way to misread this
Do not treat this as evidence that fESWT works for thumb CMC osteoarthritis. It is a single case without a control group, so the improvement cannot be separated from placebo or other factors.
