Cold Laser Therapy
Low Intensity Laser Therapy (LILT) involves using a low intensity laser diode emitting monochromatic light (with a power of 250 milliwatts or less) or an array of high intensity super luminous diodes (with total optical power between 1000-3000 milliwatts) to deliver treatment.
Conditions treated include musculoskeletal injuries, chronic and degenerative conditions and wounds. The light source is placed in contact with the skin allowing the photon energy to penetrate tissue, where it interacts with various intracellular biomolecules resulting in the restoration of normal cell morphology and function. This also enhances the amount of energy available for the body’s natural healing processes. In essence, light energy is converted into biochemical energy. The result - normal cell morphology and function are restored. The process is curative and as logic dictates, symptoms disappear.
The monochromatic coherent and polarized characteristics of the therapeutic light beam permit penetration of deep tissues without affecting normal cells. Again, it should be noted that the end result is curative with regard to the pathology, rather than symptom modulation, the conventional approach for the management of pain. Better than pain management.

What is laser therapy?
The stimulating healing effects of the laser are felt almost immediately. Results are cumulative. Because the Class IV laser delivers more power and greater depth of penetration, each treatment session is shorter and fewer treatments may be required, overall, when compared to lower-powered therapy lasers.
Are there negative effects from laser therapy?
What are the physiological effects?
By affecting and reversing the offending pathology at the cellular level, laser therapy optimizes the restoration of injured tissues to function normally, thereby alleviating the symptom of pain. The beneficial effects of laser therapy are cumulative over the course of a series of treatments.
Short Term Effects
- Production and release of beta-endorphins (substances produced by various cells in the body that inhibit the sensation of pain)
- Cortisol production is increased (cortisol is the precursor of cortisone). This enables the body to combat the stress associated with trauma or the disease process
- The short-term effect is significant in 5-10% of cases during or after the conclusion of the initial treatment, but is not as important as the long term or cumulative effect
Long Term Or Cumulative Effect
- ATP (adenosine triphosphate) production is increased resulting in improved cellular metabolism
- DNA (deoxyribonucleicacid) production; protein building block of tissue is substantially increased
- Neurotransmission is facilitated due to elevated levels of serotonin and aceytylecholine
- Mitochondrial activity is stimulated resulting in cell replication etc. (i.e. replacement, regeneration and repair of abnormal cells)
- Modulation of macrophages, fibroblasts and other cells
- Angiogenesis (formation of new blood vessels)
- Regulates cell membrane potential, essential in Na, Cl and K ion transfer (electrolyte balance)
- Cytokines and other chemicals enhancing cellular communications are released
Thermal laser versus low intensity laser therapy?
Unlike thermal lasers, the low intensity laser beam is ‘soft power’, athermal and can stimulate cellular regeneration and natural healing. Red and infra-red lasers with power outputs in the range of 10 to 250 mW belong in this category, in addition to superluminous diodes up to the 3000mW level.
Low intensity laser energy stimulates cellular function at many levels including metabolism; in essence it promotes the initiation of multiple physiological and beneficial effects in the repair and function of human cells. LILT is widely used in the medical and cosmetic fields, principally because it is non-destructive to the target tissue, while positively affecting many functions such as collagen formation, cellular metabolism, angiogenesis, lymphatic flow, etc.
How many laser treatments are needed?
In a recent clinical report on over 1,000 patients treated with the class 4 laser, patients averaged slightly less than 12 treatments to resolve their condition. In some patients one treatment is sufficient, in others up to 50 may be required.
