Low Level Light Therapy
What is Low Level Laser Therapy?
Low Level Laser Therapy (LLLT) also known as known as Photobiomodulation (PBM Therapy) is a laser or LED light therapy that improves tissue repair (skin wounds, muscle, tendon, bone, nerves), reduces inflammation and reduces pain wherever the beam is applied. Treatments typically take 15-30 minutes and should be applied two or more times a week.
How it works?
LLLT works predominately on a protein in mitochondria (cytochrome oxidase) to increase ATP and reduce oxidative stress. A cascade of mitochondrial and intracellular downstream effects lead to improved tissue repair and reduced inflammation.
The analgesic mechanism: This depends on an PBM overdose; Higher power density LLLT >300mW/cm² reduces ATP production in C fibres and A delta fibres resulting in an immediate neural blockade lasting up to approx 24 hr.
There are TWO kinds of LLLT ?
Yes, high power density is necessary for analgesia and deep tissue targets, low power density (< 100mW/cm²) is necessary to promote healing and reduce inflammation in superficial wounds, tendons and joints (the target is the synovia not the joint). LLLT do both high and low power density for best healing, deep penetration and analgesia.
