Cold Laser Therapy: Relieving Pain and Inflammation


Cold laser therapy, also known as low-level laser therapy (LLLT), is a type of medical treatment used to treat pain and inflammation. It is a non-invasive technique that delivers light energy to the body’s cells in order to stimulate healing and reduce discomfort. Cold lasers have been used for many years now, largely by acupuncture practitioners, chiropractors, and physical therapists. It is a safe, effective treatment for numerous conditions that cause pain such as tendonitis, arthritis, fibromyalgia, and more.

What is Cold Laser?

Cold laser therapy involves the application of specific wavelengths of light to parts of the body without heat or sound waves. This form of energy has long been known to have healing properties in the medical field. When absorbed by our cells, this light energy may reduce inflammation, repair tissue, and alleviate pain. Cold laser therapy is a safe, non-invasive procedure that has been proven to be effective for numerous conditions such as back pain, carpal tunnel syndrome, tendonitis, and more.

The Science Behind the Keyword

Cold lasers use low levels of non-thermal laser light to penetrate deeply into the soft tissues. The light energy is then absorbed by the cells, which triggers a biological response that results in a cascade of healing effects. Some studies show that cold lasers can stimulate the release of endorphins – natural painkillers – and increase circulation, allowing for faster tissue repair and relief from discomfort.

Benefits and Uses of the Keyword in Physical Therapy

Cold laser therapy is used to treat a variety of conditions in physical therapy. It can be used to reduce inflammation, relieve pain, increase range of motion, improve tissue healing time, and more. It can also be used for post-surgical rehabilitation as well as pre-operative preparation. Cold laser therapy is non-invasive, but research is limited on it’s effectiveness.

The Cold Laser Procedure

During a cold laser therapy session, the practitioner will place the laser device on the affected areas of the body for several minutes at a time. The amount of time that each treatment takes varies depending on the condition being treated and the size of the area being treated. Most sessions last between 10 and 30 minutes. Once the treatment is complete, the patient may experience some temporary redness or swelling at the site of the treatment.

Risks and Side Effects

Cold laser therapy is a non-invasive procedure with minimal risks and side effects. Some patients may experience slight redness, swelling, or tingling at the site of treatment but these effects usually go away within a few hours. It is also important to note that cold laser therapy may not be suitable for everyone, so it is important to consult with your doctor before beginning treatment.

Comparisons With Other Techniques

Cold laser therapy can provide some of the same benefits as other modalities such as ultrasound, electrical stimulation, and deep tissue massage. However, cold laser therapy is more focused and targeted than these other techniques. Additionally, it requires no recovery time after treatment and is non-invasive.


In conclusion, cold laser therapy is a non-invasive procedure that can provide effective relief from pain and inflammation. It is safe, and efficient, and requires no recovery time after treatment. There is limited research on its effectiveness and should not be the first line of treatment in most cases.
