What is Laser Therapy or Photobiomodulation (PBM Therapy)?
Photobiomodulation (PBM Therapy) also known as Low Level Laser Therapy (LLLT) is the application of red and near infra-red light over injuries to improve wound and soft tissue healing, reduce inflammation and give relief for both acute and chronic pain. First developed in 1967, it is now commonly referred to as PBM.
Photobiomodulation is used to: increase the speed, quality and tensile strength of tissue repair; resolve inflammation and relieve pain (analgesia).
The red and near infrared light (600nm-1000nm) commonly used in PBM can be produced by laser or high intensity LEDs. The intensity of PBM lasers and LED's is not high like a surgical laser. There is no heating effect.
The effects of PBM are photochemical (like photosynthesis in plants). When the correct intensity and treatment times are used, red and near infrared light reduces oxidative stress and increases ATP. This improves cell metabolism and reduce inflammation.
PBM devices are typically delivering 10mW - 500mW (0.01 -> 0.01 Watts). The power density typically ranges from 0.005W/Cm² -> 5 W/Cm². The device I use is a laser with an adjustable power range from 10mW – 775mW.
PBM is popularly used for soft tissue injuries, joint conditions and neuropathic pain.
Results typically take up to 6 treatments preferably applied 2-3 times per week for 2-3 weeks.
