Red Light Therapy for Equine Tendon and Ligament Injuries

Tendon and ligament injuries are slow to heal in horses. Red light therapy supports the repair process without adding pharmaceutical load.

Soft tissue injuries are the part of horse ownership nobody wants to deal with. A bowed tendon, a suspensory issue, a check ligament strain — they're all slow, frustrating, and prone to reinjury if you rush rehab. Red light therapy isn't a fix-all, but it's one of the more useful tools to have in the rehab toolbox.

Why Tendons Heal So Slowly

Tendons and ligaments have poor blood supply compared to muscle. Less blood flow means slower delivery of the cells, oxygen, and nutrients needed for repair. That's why a tendon injury can take six to twelve months to heal properly, and why so many of them come back if you put the horse back in work too soon.

Where Red Light Comes In

Red light therapy (and near-infrared light specifically) penetrates into the deeper soft tissues. The light energizes the mitochondria of the cells in the area, which improves cellular repair capacity, reduces inflammation, and supports the production of collagen — the structural protein tendons are built from. Studies on tendinopathy in both human and animal subjects have shown faster recovery times when red light is part of the rehab plan.

It pairs well with PEMF therapy, which improves circulation in the area. Better circulation plus better cellular repair capacity equals a more supportive environment for healing. We do a lot of these combination sessions for performance horses on stall rest.

Where It Fits in a Rehab Timeline

• Acute phase (first 1–2 weeks): work with your vet on diagnostics, icing, and rest. Red light can begin once your vet clears it.
• Subacute phase (weeks 2–8): regular red light and PEMF sessions to support tissue repair while the horse is on controlled exercise.
• Remodeling phase (months 2–6+): continued sessions help the new tissue organize properly as work resumes.
• Return to work: maintenance sessions during the gradual return to full work to support the healing tissue under load.

A Note on Imaging and Vet Coordination

Don't skip imaging. Ultrasound (and sometimes MRI) is what tells you whether a tendon is actually healing or just feeling better. Therapy can make a horse seem sound before the tissue is structurally ready. Always coordinate with your vet, follow their rehab schedule, and use ultrasound checks to time progressions. Therapy is part of the plan, not a substitute for the plan.
