The wavelengths of photons determine their effect on the tissue. The smaller the wavelength, the greater its ability is to penetrate tissue. Lasers affect tissue because the photons delivered to the cells and tissue trigger biologic changes and biochemical reactions. Photons are absorbed by cytochromes (respiratory chain enzymes) within the cell mitochondria and the cell membranes. This leads to ATP and DNA production, stimulating cellular metabolism and growth, potentially accelerating tissue repair and cell growth of structures. Lasers can be used to provide analgesia through the release of endorphins and enkephalins, help with wound healing and improve bone and cartilage health.
The MLS Harmony Laser has a proprietary and patented handpiece that delivers two wavelengths in a synchronized fashion. The 808 nm wavelength provides anti-inflammatory and anti-edema effects via a continuous wave delivery. The 905 nm wavelength provides analgesic effects, with some of the same effects of the 808 nm wavelength. The 905 nm wavelength is delivered using pulsed mode laser energy.
Advanced Veterinary Care Group is one of the first three sites in the Midwest for this exciting new therapy.
Indications for Laser Treatment
- Trigger Points
- Lick Granulomas
- Post-operatively (especially metabolically compromised patients)
- Muscular injuries
Improvement is often seen after 2-5 treatments. Generally, acute conditions require a closer interval, but fewer total treatments. For example, 2-3 treatments in the first two weeks, 1-2 in the following weeks, then once weekly until resolved. Chronic conditions usually require more treatments, but they can be less frequent. For example, two treatments weekly for the first 2-4 treatments, then once weekly for a few weeks, then every other week for a few weeks until a maintenance schedule is reached. The patient’s condition may temporarily worsen 6-24 hours after laser treatment as the healing process is stimulated. This is more likely to occur with chronic conditions.
Laser treatment for wounds promotes healing and reduces pain. The speed of granulation, scar tensile strength and healing time are enhanced. Post-surgical healing times can be reduced, especially in old or debilitated animals like diabetics.
Laser therapy helps by the reduction of pain and swelling. There can be noticeable improvement in range of motion as well. Laser energy influences synovial fluid and membranes as well as articular cartilage. Conditions may temporarily worsen 6-24 hours after treatment during the healing process.
Laser treatment can be used for painful conditions to assert and analgesic effect. Painful areas are treated along with trigger points. Identified trigger points include infraspinatus, quadriceps, pectineus, iliocostalis lumborum, pereneus longus, semimemranosis and -tendinosis, tensor facia latae and gluteus medius.
Intervertebral Disc Disease
When owner cannot or will not opt for surgery, laser therapy can lessen pain, swelling and inflammation to affect a positive response in return of neural function. Treatments need to be daily at first, then 1-3 times weekly until satisfactory results are achieved.
