PBM light therapy Flashcards
what is PBM
exposure to daylight or specific waves of light
what is LLLT do
reduce inflammation
promote tissue repair
induce analgesia
not for cutting
what type of light is LLLT
monochromatic coherent colluminated
what is the depth and use of level III laser? IV?
1cm depth, must be touching skin
3-4cm, doesnt need to contact skin
how does the PBM work on tissues
supresses cox 2 pathway by being absorbed by Cytochrome c oxidase in mitochondria
three things cytochrome c oxidase does
release NO
modulate ROS
icnrease ATP
why is decreasing ROS a good thing
ros causes inflammation
what does NO normally do
antiaging, microcirculation, insulin regulation, increase cognitive performance, kidney function
overall effects of PMB
down stream effects
increase bone formation, cartilage protection, nerve and muscle regeneration
decrease inflammation
four levels
primary- cyto c
secondary- NO, ROS, ATP
tertiary- cell proliferation, migration, decrease necrosis and inflammation
quaternary- bystander cells affected my secretions from other cells
myofacial trigger points
palpable nodules in taut muscle bands that lead to issues, spasms
difference between watts in III and IV
III 1-500 watts
IV >500 watts
lower wattage lasers are better for treating
superficial structures
no laser on
growth plates, pregnant uterus, fontanels, tumors, eyes, thyroid
where to find treatment doses
world association of laser therapy
