1. What is Cold Laser Therapy?
Also known as low-level laser therapy (LLLT), low-intensity laser therapy (LILT), cold laser therapy (CLT), laser light therapy or photo bio-stimulation, cold laser pain relief treatments are amongst the earliest therapeutic methods used by humans. Most of the authors have stated that laser therapy was started in 1967, some years later, Gordon Gould gave the acronym LASER (Light Amplification by Stimulated Emission of Radiation). It is a light-based technology and is known to be very effective in the treatment of musculoskeletal problems and wound healing.
Cold laser therapy (CLT), is used worldwide and is non-poisonous without causing any invasion or puncture in the body. CLT is a pain-free process with no toxic side effects. Patients begin to recover within the first treatment, with long-term treatment requiring a few weeks of treatment. It is done with the help of light energy using different tools and technologies to treat your body naturally from many ailments.
CLT, unlike other treatment processes, is pain-free and it does not involve the use of medicines or surgery. Though this treatment was introduced many years ago, it is still new to people and is very helpful for those who are looking for a non-invasive treatment. The reason why it is called ‘CLT’ is that it does not involve the heating of tissues.
It is also evident that CLT is related to pain management. We all know that pain affects physical and mental health but what we did not know is that severe or chronic pain could result in very critical mental, familial, marital and other problems. It also results in a decrease in the life span of the affected individual. We all know that many diseases (including pain) are treated with the help of natural remedies like sunlight… but “SULFA” in 1932 was discovered by Gerhard Domagk. With this discovery, the revolution of drugs started. In this perspective, alternative modalities including CLT are also considered effective. Infact, CLT is considered two times more effective than NSAIDs for the treatment of osteoarthritis pain.
2. How it Works!
The procedure of CLT involves the application of various wavelengths and outputs of low-light towards the selected area. When low-level light is focused on a specific tissue, that tissue absorbs light and regeneration is stimulated. Damaged cells hurl back with physiological reactions and the reaction is caused by near-infrared light.
- Tissues which are apparent and present on the outside of bodies are cured with the wavelength ranging from 600-700 nm.
- For non-superficial or internal wavelengths, the range falls in between 780-950 nm.
CLT is a very easy procedure to perform as it takes only a few minutes and the patient feels no pain, piercing or any kind of vibration. Click here to see our customer testimonials abiding by this.
The procedure of how CLT work is unclear, but it helps to relieve the pain associated with swelling by lowering the levels of prostaglandin E2 (PGE2), interleukin-1 beta (IL-1 beta), tumor necrosis factor-alpha (TNF-alpha), cellular influx of neutrophils and granulocytes, oxidative stress, edema, and bleeding in a dose-dependent manner. The dosage of CLT ranges from 0.3 to 19 J/cm2. CLT has an increasing effect on cells at a low dosage and an oppressive effect at high dosage. Another mechanism for cold laser pain relief is carried out by evoking the mitochondrion to raise adenosine triphosphate (ATP) production in order to increase the reactive oxygen species (ROS), which in turn, influences redox signaling, affecting intracellular homeostasis of the proliferation of cells.
3. Applications of CLT
CLT, due to its vast effectiveness, is used in various ways. Cold laser pain relief treatments are done primarily as it’s effective in repairing tissues, pain and inflammation.
Some of important uses or applications of CLT include:
Injuries and Sprains
Medicines and physicists frequently use CLT in the healing of small injuries and sprains. These injuries include all types of bodily ailments but mainly include ligament sprains, knee pain, neck pain, lower back pain and pain associated with muscle convulsions.
CLT is also used in the healing of swollen tissues of the mouth by dentists. This could be swollen gums etc.
Pain and Inflammation
Laser treatments for pain and inflammation are done by CLT to treat acute or severe pains that occur due to diseases such as fibromyalgia and carpal tunnel syndrome.
Rejuvenation of Skin
Dermatologists use CLT to promote refreshing the dull or dead skin which occurs due to burns, acne, and rashes. Old age people get this treatment done to uplift their skin and look fresh.

4. Future of CLT
In the future, CLT has bright chances to be used in many fields and in the treatment of various syndromes which are non-treatable as of now including parkinson’s disease, spinal cord injury, brain injury, memory loss etc.
Among other things, it should also be taken under consideration that CLT could be used at home with proper precautions. The laser can normally be used at home for losing weight, to quit smoking, growing hair, checking blood pressure etc.
5. Pros of CLT
· Surgery replacement
· Fast healing
· Productive under unfavorable conditions
· Scientifically approved
· Gain revenue with this unique modality
· Drug replacement.
6. Precautionary Measures
· Engineering controls: which are already available safety features provided by the manufacturer with the consent of IEC and FDA (CDRH) standards.
· Procedural controls: These are the facilitative measures given by health care facilities.
· Administrative controls: This is the structure or measures of a laser safety program.
All of these measures must be kept under controlled supervision.
7. Case Study
Laser therapy has been in use for a long time. One case study by Dr. Stephanie Leonard highlighting the results she got using ‘superpulsed laser’ on second-degree burns. She was not only capable of providing a cold laser pain relief treatment, but also received commendable responses in the treatment of burnt areas. So the healing of lesions or wounds is one of the peculiar effects of therapeutic lasers. This is a very effective example of these types of treatments by CLT.
