Class IV Laser (Light Amplification by Stimulated Emission of Radiation) Therapy uses an intense beam of light directed into tissues. Class IV lasers can be broken down into two categories; surgical & therapeutic. A surgical laser cuts tissue.
In contrast, a therapeutic laser heals tissue. Laser therapy reduces pain, reduces inflammation, and accelerates healing by a process called photobiostimulation.
Science has known for many years about the phenomenon of light producing beneficial effects on animals and other organisms. A basic example of photobiostimulation is photosynthesis, which occurs both in plants (to produce oxygen) and in skin (to produce Vitamin D). The Class IV laser is simply a way to target this light to produce fast and specific results. Deep, penetrating light allows relief of pain by the release of endorphins and stimulates injured cells to heal at an accelerated rate.
This laser allows us to ease pain and improve mobility without the use of surgery or pharmaceuticals.
Some disorders that respond positively to laser therapy;
- Hip Dysplasia
- Skin conditions & irritated anal glands
- Post surgical pain relief & increased healing
These disorders are commonly result in pain, inflammation and scaring. Treatment times may vary between 3 -5 minutes for each affected area (multiple times on a flexible schedule) producing a gentle and pleasant warming sensation.
Commonly asked questions regarding the therapeutic laser;
How does it reduce pain?
- The laser effects nerve cells and nociceptors (sensory receptor reacting to a damaging stimuli responding through the spinal cord/brain) by increasing their stimulatory threshold. It is also causing a reduction in neuronal impulses while increasing the release of endorphins. Together these effects will result in a decrease in the animals pain perception.
How does it reduce inflammation?
- The laser causes a decrease in release of prostaglandins & inflammatory mediators and reduces edema through dilation of lymphatics.
How does it accelerate healing?
- The laser accelerates healing by an increase in blood flow caused by vasodilation, by increasing angiogenesis(growth of new blood vessels from pre-existing vessels)and capillary production, increased release of cytokines and finally by stimulation of fibroblast activity and collagen production.
