Low-Level Laser Therapy

What is Low Level Laser (LLLT / Cold Laser)?

In simple terms, laser is amplified light studies have shown that all cells in the body respond to light. The laser kit I use consists of a 660nm probe and an LED cluster probe. The 660nm probe can penetrate up to 8cm into the body tissues and is a great way of accessing large muscle groups or deep injuries. The kit has a vast number of settings, meaning it is possible to be very specific about which cell type, depth of tissue, and cell response is required.

As laser does not vibrate, there is little or no sensation during the treatment and it is accepted very well by animals even very touchy ones! The lack of vibration also means it is safe to use on fractures, and where there are pins or plates.

How does LLLT work?

In short, laser stimulates cell processes by increasing the activity of cell mitochondria, thus accelerating cell replication and healing. It also reduces pain and inflammation by means of vasodilation and inhibition of pain receptors. Levels of serotonin and endorphins also increase during laser treatment, meaning most animals enter a state of relaxation. It can also be used to neutralise infection and bacterial growth.

What does LLLT do?

LLLT can help with a wide range of conditions, including:

  • Wound healing - recovery from accidental or post-surgical wounds
  • Soft tissue injuries and bruising
  • Muscle spasm
  • Tendon and ligament injuries
  • Scarring
  • Fractures
  • Blemishes - splints, windgalls, capped hocks, etc
  • Thrush and mud fever
  • Joint pain, i.e. due to arthritis.

In many cases, muscle pain or bruising can be vastly helped or resolved in just one session. For treatment of wounds, bone / tendon / ligament injuries, thrush, or splint reduction, I recommend a course of 4-8 sessions (discounted block bookings available).

If you have any enquiries about whether your animal would benefit from LLLT, please do not hesitate to contact me.


I attended an Equine Laser Therapy course in January 2010 with Omega Laser Systems, and in June 2010 I spent a day with well-known practitioner Janet Lloyd-Jones to consolidate this learning and to add skills in using the laser kit on dogs and small animals. I have since (July 2011) attended an introductory course in Equine Laser Acupuncture, also with Omega Laser Systems.
