Cold Laser Therapy or Low Level Laser Therapy (LLLT) is a treatment that utilizes specific wavelengths of light to interact with tissue and is thought to help accelerate the healing process. It can be used on patients who suffer from a variety of acute and chronic conditions in order to help eliminate pain, swelling, reduce spasms and increase functionality.

How Cold Lasers Work

Cold lasers are handheld devices used by the clinician and are often the size of a flashlight. The laser is placed directly over the injured area for 30 seconds to several minutes, depending on the size of the area being treated and the dose provided by the cold laser unit.

During this time, the non-thermal photons of light that are emitted from the laser pass through the skins layers (the dermis, epidermis, and the subcutaneous tissue or tissue fat under the skin). 

Cold Laser Therapy Advantages

Cold laser therapy is a non-invasive procedure, meaning that it does not require a surgical incision. This means that there is no prolonged recovery time.

Laser therapy also does not involve taking any medications, and many patients prefer to avoid taking medications. Studies have so far found that cold laser therapy does not have serious side effects when used properly by a doctor

Potential Cold Laser Therapy Disadvantages

Cold laser therapy does have several disadvantages.

Patients do not typically get full relief or resolution from their pain symptoms after the first treatment. It takes a series of treatments, usually 8 to 30, depending on the severity and duration of the condition.

Patients often have to return to the doctor for treatments at least 2 to 4 times per week. Old injuries may be aggravated for a few days after treatments, but for most patients this sensation is short term, lasting for a couple of days.
