Laser Therapy is used for the relief of pain, to accelerate healing and decrease inflammation. When the light source is placed against the skin, the photons penetrate several centimeters and get absorbed by the mitochondria, the energy producing part of a cell. This energy fuels many positive physiological responses resulting in the restoration of normal cell morphology and function. Laser Therapy has been successfully used to treat a broad range of medical conditions, including musculoskeletal problems, arthritis, sports injuries, post-surgical wounds, diabetic ulcers and dermatological conditions.
The central goal of laser therapy is to stimulate the cell to perform its natural functions, but at an enhanced rate. Targeted in hemoglobin and cytochrome c oxidase, the high power diode laser could help the respiration and then in result have a good performance therapy. In sharp contrast to “Cold lasers” which provide no feeling or sensation, high power diode laser therapy will provide warm and smoothing feeling.
Unlike many pharmacological treatments that mask pain or only address the symptoms of disease, Laser Therapy treats the underlying condition or pathology to promote healing. This means that the treatments are effective and the benefits of Laser Therapy are long lasting.
The dosage of laser energy is measured in joules [J] and is equal to the power in watts of the laser multiplied by the treatment time. A 1 watt continuous wave laser delivers 1 Joule/sec at the surface. For a pulsed laser, the laser is off part of the time so the delivered power is derated by the duty-cycle (ratio of ON to TOTAL time). A laser with more power, measured in milliwatts (mW) or watts (W) or a higher duty-cycle laser can deliver more energy in less time. Delivering joules is where the bulk of the work is done when treating patients. The class of the laser (1 through 4) is largely controlled by the power level from each output beam because they are somewhat proportional to the potential for damage.

Many laser companies make a huge mistake on their protocols. They will use the WALT recommended target energy (which is lower than many US manufacturers recommend) "at depth" (4-8 joules) as the requirement for the output of the laser. This is a huge mistake. At a depth of 1 inch (2.54 cm), up to 80% of the energy has already been absorbed on its way to the damaged area so you must increase the dosage out of the laser to accommodate for the lost energy. That means that to get 8 joules/cm2 at depth can requires 26 joules/cm2 at the surface. Since most system have a treatment are of about 1 inch2 (1 inch2 = 6.4 cm2), the laser should output 167 joule for a single point. If you are moving the laser around, you can easily see why many lasers are underpowered. If you want 8 joules/cm2 at depth over a 3 x 5 you need 2505 joules out of the laser. You can use the table below to see the treatment times for a range of dosage requirement.
How Much Power is Enough?
Too Little: In our summary of laser power requirment, you can see that there are many inexpensive over-the-counter lasers might help with small issues are drastically underpowered for many cases. According to the FDA limitations, OTC lasers are limited to 5 milliwatt (mW). If we look at the theoretical treatment times based on the power of the laser, it is easy to see that these products will never reach the typical dosages that you would get in a doctor's office or clinic in a reasonable time (FYI, one of the largest back pain clinic in the Colorado uses 7000 joules per patient or more). With a 1mW system, it takes 5.7 days to achieve 500 joules at the surface of the skin and 500 joules over a large area (like a back) or into a deep area (like a hip) is not delivering any significant energy. These low-powered lasers are often more powerful than led power system but they are massively underpowered when compared to professional systems. We do not sell any systems with less 500mW of power because these systems do not provide consistent efficacy.
