LLLT 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. Usually applied by a doctor, therapist or technician, treatments typically take 1 - 10 minutes and should be applied two or more times a week.
How it works?
LLLT works predominately on a protein in mitochondria (cytochrome c oxidase) to increase ATP and reduce oxidative stress. A cascade of mitochondrial and intracellular downstream effects lead to improved tissue repair and reduced inflammation.
How much is enough, how much is too much?
There is a dose response: not enough power density and there is no effect, too much and there can be inhibitory effects which can slow down healing and lose the anti-inflammatory effects.
The analgesic mechanism
This depends on an LLLT 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.
So there are actually 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). Nouifo do both high and low power density for best healing, deep penetration and analgesia.
