Low Level Laser Therapy (LLLT) is a drug-free treatment that uses a beam of light to deeply penetrate tissue. The laser energy is absorbed by the cells, initiating a chemical change that reduces pain, reduces inflammation, and speeds healing. Treatment protocols are unique to each patient's condition. For some conditions, a single treatment may be all that is required. For some chronic and difficult conditions, a series of treatments may be necessary to get the maximum benefit. In addition to treating pain and inflammation, it is also used to prevent injury and to maintain peak performance in equine athletes.
