Light therapy may soothe wrist pain without surgery

First seen Aug 26, 2026 · Last updated Aug 27, 2026 · Updated 1 time
Summary
This trial tests whether low-level laser therapy can reduce symptoms and improve hand function in people with mild-to-moderate carpal tunnel syndrome, a common condition where the median nerve in the wrist is compressed. Participants will be randomly assigned to receive either active laser therapy, a sham (inactive) laser, or paraffin bath therapy, all alongside standard care like wrist splinting and exercises. The study measures changes in symptom severity, nerve function, and hand strength before treatment, right after the 3-week session, and at a 3-month follow-up.
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) using a device that delivers 670 nm wavelength light to the wrist, compared with paraffin bath therapy and a sham (inactive) laser.
- What this could lead to
- If effective, low-level laser therapy could become a non-invasive, drug-free option to reduce pain and numbness and improve hand function in people with mild-to-moderate carpal tunnel syndrome.
- What could go wrong
- This is a relatively small trial, and results may not apply to severe cases. The therapy might not outperform the sham or paraffin bath, and benefits may not last beyond three months.

Inclusion Criteria: * Diagnosis of mild-to-moderate carpal tunnel syndrome (unilateral or bilateral), confirmed by paresthesia and pain in the median nerve distribution, positive Tinel's and Phalen's signs on physical examination, and electrophysiologically confirmed mild-to-moderate CTS * Age 18 years or older * No cognitive impairment * Provision of informed consent to participate in the study Exclusion Criteria: * Cognitive impairment * Severe-stage CTS with surgery planned * Neurological disease affecting the extremity with CTS * Active local infection at the treatment site (e.g., cellulitis, erysipelas, thrombophlebitis) contraindicating physical therapy * Cardiac pacemaker (contraindication to physical therapy and electrodiagnostic studies) * Prior wrist fracture or laceration at the treatment site * Injection therapy for CTS within the past 3 months * Prior CTS surgery with recurrence * Active malignancy under treatment * Pregnancy
