Can light therapy unlock stiff fingers?
NCT ID NCT07753460
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This trial tests whether adding low-level laser therapy to a standard splint can ease the pain and locking of trigger finger, a common hand condition. About 91 people with trigger finger will receive either real laser treatment or a sham (inactive) laser, three times a week for four weeks, while all wear a splint. Researchers will compare changes in pain, triggering severity, and hand function between the two groups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Low-level laser therapy (LLLT) plus a splint, compared to a sham laser plus a splint
- What this could lead to
- If effective, adding low-level laser therapy to standard splinting could offer a non-invasive way to reduce pain and finger locking, potentially delaying or avoiding the need for injections or surgery.
- What could go wrong
- This is a relatively small trial, and the sham-controlled design means the true benefit may be modest. Low-level laser therapy is generally safe, but results may not apply to all cases, especially severe ones.
