Cold Laser Therapy in Ottawa – LOW LEVEL (LLLT)

At EWC, we provide the latest technology in order to increase the speed and degree of recovery for all of our patients. Low Level Laser Therapy is a safe, effective, and virtually side-effect free method to help treat patients with chronic injuries and many other health conditions. LLLT has been shown to work wonders in reducing pain, speeding injuries, reducing inflammation, and increasing the effectiveness of complimentary treatments.



LLLT (Low Level Laser Therapy) is a light therapy using lasers or LEDs to improve tissue repair, reduce pain and inflammation wherever the beam is applied. Usually applied by a therapist, treatments take about 10-15 minutes and should be applied two or more times a week.

LLLT is used to: increase the speed, quality and tensile strength of tissue repair; resolve inflammation and relieve pain (analgesia). The red and near infrared light commonly used in LLLT can be produced by laser or high intensity LEDs. The intensity of LLLT lasers and LED’s is not high like a surgical laser. There is no heating effect.



The effects of LLLT are cold not thermal, thus photochemical processes are effected. Hot lasers in the medical world are used for surgical precision while cold lasers are used for healing precision. During treatment of the tissue with the laser beam, an interaction between cells and photons takes place, thus a photochemical reaction. Photons from the laser affect the tissue at the cellular level. The cold laser enters the tissue, alters cell membrane permeability, and at the cellular level is absorbed in the mitochondria of the cell creating physiological changes

Benefits of LLLT


The laser accelerates cellular reproduction and growth

Pain Reduction (Chronic & Acute)

Faster wound healing: The laser stimulates fibroblast development in damaged tissue. The reduction in recovery time is an important consideration.

Increased metabolic activity: Helps the body increase output of specific enzymes, greater oxygen to blood cells and more effective immune response are induced by laser.

Reduced fibrous tissue formation: The laser reduces the formation of scar tissue following tissue damage from cuts, scratches, burns, or following surgery.

Anti-inflammatory action: The laser reduces swelling caused by bruising or inflammation of joints to give improved joint mobility.

Increased vascular activity: The laser stimulates lymph and blood circulation, to allow the affected tissue to have the best possible circulation.

Stimulated nerve function: Slow recovery of nerve function in damaged tissue can result in “dead” limbs or numb areas. Laser will speed the process of nerve cell reconnection to bring the numb areas back to life.

Laser also increases the amplitude of action potentials to optimize muscle action.



Because LLLT is as safe as it is effective, there are no known long-term side effects of this form of light therapy. Other than averting your eyes from the laser’s red or infrared light, the FDA has found no other red flags or adverse side effects from using LLLT. Because the light emitted does not cause your skin to burn, there is no risk of pain except under certain conditions.

What are the Contraindications?


There are, however, people with health conditions or disorders that should speak to their doctor before using LLLT, as some contraindications or risks are involved. Low-level laser therapy should generally not be used over:


 Malignant tumours: With the physician’s permission, LLLT is commonly used to treat cancer side effects or for pain relief during the final terminal stage of the illness.



 Developing Fetus: While there is no evidence to suggest that LLLT during pregnancy is harmful, there is not enough research and evidence yet to suggest otherwise.

 Eyes: One of the first safety precautions our parents ever taught us was to avoid looking directly at the sun in case of eye damage. Maintaining that same philosophy with LLLT is common sense. During your LLLT session, you will be given a pair of tinted safety
