Red light therapy
Photobiomodulation. Wavelength, distance and duration determine the delivered dose.
Evidence category: Systematic review. This describes the source category, not approval or certainty.
Regulatory statement in source: Not separately recorded; do not infer approval from the evidence category.
Red and near-infrared photobiomodulation applies low-level light to tissue. A meta-analysis of 17 randomised trials in tendinopathy found light plus exercise beat sham plus exercise for pain and function, but no advantage over other treatments, at very low to moderate certainty. A systematic review of four trials in primary headache judged the evidence insufficient to support use. A broader review notes that results vary because devices, wavelengths and delivery are not standardised. The evidence is weak and condition-specific.
Benefits reported in the imported source
- Added to exercise for tendinopathy, it beat sham plus exercise for pain and function in pooled trials
Risks and limits
- It showed no advantage over other treatments, at very low to moderate certainty
- For primary headache, reviewers judged the evidence insufficient to support use
- Devices, wavelengths and delivery are not standardised, so results vary
Source bottom line: Red and near-infrared light helped tendinopathy pain alongside exercise, on weak evidence.
Uncertainty: Reference information only. Not medical advice.
Study protocols — reports, not instructions
835 participants with tendinopathy across 17 randomised trials, mostly elbow and rotator cuff
- Reported regimen
- near-infrared photobiomodulation at 810-905 nm, 0.5-5 J/cm2, 7 to 24 sessions given 2-5 times a week, alone or added to exercise
- Duration
- most trials measured at the end of 2 to 4 weeks of treatment, with follow-up at 3 months
- Reported outcome
- Added to exercise it beat sham plus exercise for pain and function, but not other interventions; certainty was very low to moderate.

Community and practice descriptions
Accounts of a practice are not evidence of safety or effectiveness. Words such as “standard”, “safe” or “recommended” describe the source account, not verified consensus or this wiki’s advice. Commercial and self-published citations are retained for traceability, not vendor endorsement or independent clinical corroboration.
