Photobiomodulation has been previously known as light laser therapy or cold laser therapy. Light laser therapy is typically in the infrared wavelength, although some lasers also utilize blue wavelengths and red wavelengths for certain therapies as well. The blue and the red wavelengths are typically using LEDs. There are also different classes of lasers available. Photobiomodulation is generally well tolerated. It offers an alternative or adjunct treatment for accelerating wound healing and pain management.
Laser therapy has the benefit of having few side effects. Pigmentation of the skin and excessive amounts of fur can definitely affect the absorption of laser light. Close contact with the skin allows for better penetration of the lasers.
Lasers are currently being used for a variety of conditions and more information is becoming available every year. Like any treatment regimen, chronic conditions like osteoarthritis may take time to respond and improvement depends on the severity of the condition. Lameness such as with elbow arthritis may not resolve as the joint has undergone changes that result in a decrease in range of motion. While inflammation and pain may improve, the bony and muscular changes probably will not. So, how does one assess degree of improvement? It would be nice if our pets could tell us, but instead we have to look at their every day routine. Some dogs will whine or whimper when in pain, but others are very stoic. In the latter case, activity level, willingness or reluctance to go on walks, speed and duration of walks or their overall activity can be signals as to how the pet is doing.
Lasers have the potential of accelerating wound healing. Obviously, if the cells involved with tissue repair are working at optimum levels, then you probably will not see a huge difference. However, most wounds are compromised to some degree by tissue damage or bacteria. Even with the best case scenario such as a sterile surgical incision site, the laser can help minimize pain post surgery.
