Cold laser therapy is low-intensity laser therapy that stimulates healing while using low level laser light.
The technique is called “cold” laser therapy because the low levels of light aren’t enough to heat your body’s tissue. The level of light is low when compared to other forms of laser therapy, such as those used to destroy tumors and coagulate tissue.
Surgical and aesthetic lasers heat the tissue being treated. True to its name, cold laser therapy does not.

Low-level laser therapy (LLLT)
low-power laser therapy (LPLT)
soft laser biostimulation
photobiomodulation

During this procedure, different wavelengths and outputs of low-level light are applied directly to a targeted area. The body tissue then absorbs the laser light. The red and near-infrared light cause a reaction, and the damaged cells respond with a physiological reaction that promotes regeneration.

Superficial tissue is commonly treated with wavelengths between 600 and 700 nanometers (nm). For deeper penetration, wavelengths between 780 and 950 nm are used.

Although you’ll feel the laser device touching your skin, the procedure is painless and noninvasive. There will be no sound and you’ll feel no vibration or heat. Each treatment typically takes only a few minutes.

Laser stimulates the mitochondria of the cell to produce more Adenosine Tryphosphate (ATP- or basic energy cell) to accelerate tissu repair.

Laser Technology effectively removes the pain signal at source by rebalancing the Sodium, Potasium pathway. (Reareched by Harvard Medical School in the 2010)

Laser Technology increases the production of Nitric Oxide by over 700 percent increasing vasodilution and decreasing inflammation

There are thousands of published studies that describe the positive effect of laser therapy. These studies range from studies on individual, cell types to vo double blind control studies. The area of study range from wound healing to musculo sceleton conditions and have been conducted on different types of laser devices.There are also many books on the subject, one very good among them is ‘Low Level Laser Therapy annd Clinical Practice wirtten by Jan Tornar and Lars Hodey and Photon Theory of Light by Albert Einstein in 1969.

Doctors, dentists, physical therapists, and other medical professionals use cold laser therapy in a variety of ways. The main uses for cold laser therapy are tissue repair and relief from pain and inflammation.

Sports medicine and physical therapy practices often use cold laser therapy in the treatment of minor injuries and sprains, such as:

Ligament sprains, Muscle strains, Tendonitis,  bursitis, Tennis elbow, Neck Pain Lower Back Pain, Wound healing, Diabetic Neuropathy, Trigeminal Neuralgia, Tinnitus, TMJ (Temporomandibular Joint) Disorders, Knee Pain, Fibromyalgia, Carpal Tunnel Syndrome Heel Spur, Plantar Fasciitis, Pain associated with muscle spasms, It’s also used to help reduce swelling and promote healing of the joints and soft tissue.

Cold laser therapy is also used to treat difficult-to-heal wounds, including wounds related to diabetes.

Acupuncturists use cold laser therapy for clients who are uncomfortable with needles. The low-level laser beams can stimulate your acupoints the same way needles do, but without piercing your skin.

The use of cold laser therapy is growing in traditional medical practice and as a complementary or alternative therapy. It’s approved by the U.S. Food and Drug Administration (FDA) for a number of conditions in 2002.

Cold laser therapy is considered safe when performed under the care of a doctor or qualified practitioner. On the plus side, it’s also non-invasive and painless. It doesn’t require medication or other preparation either.

Cold laser therapy shouldn’t be used on carcinomas or cancerous lesions. It should also be avoided on the thyroid or eyes. Since the effect of cold laser therapy on unborn children is unknown, it’s suggested that pregnant women avoid this type of treatment.

One of the drawbacks of this therapy may be time. While each cold laser therapy session only takes a few minutes, it may take as long as a month (with as many as four treatments a week) before you can gauge its effectiveness.

The depth of penetration of laser lights depends on many parameters such as laser wave length and power. The higher the wavelenghth, the deeper the penetration. Our medical laser can provide a direct penetration of Tissue 5 CM into and an indect penetration into upto 10 CMs.

You might feel a slight tingling sensation, but you won’t feel heat or cold. It’s also painless. There’s no lengthy recovery time, so you can go home right away.

Patients would be recovered and get relieved from the pain if the treatment taken as per the specialists advises you. The therapist will go through the patients’ health history and other required report before you undergo the treatment. And the patient must attend the sessions as your body, age, physical as well psychologicl conditions and severity of the pain suffered and stage of the health issue. Positive thoughts of the patients would help fast recovery.

Cons
you may need up to 30 treatments before you feel pain relief
may not be covered by your insurance

Therapitic lasers have been cleared by health US and FDA to treat acute and chronic knee pain. Over 4000 Clinical studies have been conducted world wide. 

Laser can treat 100 treatable conditions including arthritis, wound healing, addiction rehabilitation, headache and carpel tunnel syndrome among many others including stress related conditions.
