How to calculate laser therapy dose?
Dosage expressed as J/cm² is inadequate. A 500mW laser with a beam area of 0.25Cm2 used for 20 seconds delivers 40 J/cm². A 200mW laser with a beam area of 0.1Cm2 used for 20 seconds delivers 40 J/cm². A 30mW laser with a beam area of 0.015Cm2 used for 20 seconds also delivers 40 J/cm².

What is a WALT?
World Association for Laser Therapy (WALT) was founded in 1994 in Barcelona, Spain at the congress for The International Laser Therapy Association (ILTA) and The International Society for Laser Application in Medicine (ISLAM). When these two international organizations merged WALT was formed. It is the world’s leading organization for the purpose of promoting research and education in the field of photo-biostimulatory treatment with lasers and other light sources. Currently, the worldwide organization WALT and its members comprise the world’s leading experts in all forms of treatment with photo-biostimulatory light treatment; including Low Level Laser Therapy (LLLT) or Photobiomodulation Therapy (PBMT) which is the best technical term.
Is the World Association of Laser Therapy responsible for the application of laser therapy in patients?
The list may be subject to change at any time when more research trials are being published. World Association of Laser Therapy is not responsible for the application of laser therapy in patients, which should be performed at the sole discretion and responsibility of the therapist.
What is LLLT laser therapy?
What is Low Level Laser Therapy (LLLT) and Does It Work? Low level laser therapy represents a solution for a number of medical issues, which is based on the application of low power laser, on various parts of the body.
Why is LLLT used?
LLLT treatment is often preferred by athletes, as it guarantees faster recovery after intense periods of treatment (exercise-induced muscle fatigue). From another perspective, the low-level laser therapy can offer more rapid healing in case of various injuries.
Why do dentists use cold lasers?
Dentists, for instance, rely on the cold laser to treat inflamed oral tissue and heal ulcerations. The cold laser is beneficial for skin rejuvenation and dermatological conditions, such as acne, psoriasis and burns. It might also be used to treat wounds that heal with difficulty, as it happens in case of diabetes.
Who discovered the infrared light?
Infrared light history. History tells us that it was the Hungarian physician and surgeon, Endre Mester , who discovered the biological effects of the low power laser. As time passed, and research evolved, the equipment used for the application of the low level laser therapy became more advanced.
Why do you need protective eyewear when you have a laser?
This is because looking at the laser directly can cause retina damage. Even the diffuse reflection of a laser can damage the eyes, in case of certain laser types.
What is LLLT laser?
LLLT, short for low-level laser therapy is also known as photobiomodulation (PBMT), cold laser therapy, low-intensity light therapy, and soft laser therapy. Studies have confirmed that such kind of applications has excellent pain-relieving properties, as well as the ability to improve the functioning of various cells.
Does laser therapy help with back pain?
The low level laser therapy offers pain relief in those who suffer from chronic low back pain and it can stimulate wounds to heal faster. It helps with acute conditions, such as the frozen shoulder and it eliminates the muscle pain associated with intense physical training (exercise-induced muscle fatigue). LLLT is effective for conditions such as plantar fasciitis, providing relief from both pain and inflammation.
2 Important Parameters for Calculating Laser Therapy Dose
1. The Size of the Area to Treat#N#Treatment Area (cm 2) = length (cm) x width (cm)
Real-Life Dosing Example
I want to treat a 10 cm by 10 cm area with 10 joules/cm 2. To calculate my total joules required to deliver the appropriate dosage, I will first calculate treatment area:
How Long Would It Take To Deliver that 1,000 Joules in Continuous Wave?
How long would it take to deliver 1,000 joules in continuous wave? Delivering doses in relevant treatment times is the key to why many clinics are moving to high-powered lasers. To calculate the treatment time we will use the following formula:
