Laser Therapy ?
LEVEL LASER THERAPY DEVICES ARE FDA CLEARED FOR CERTAIN PAIN
CONDITIONS. ANY USES BEYOND THOSE FOR WHICH THEY HAVE BEEN
CLEARED ARE INTENDED FOR INVESTIGATIONAL
AND CLINICAL TRIAL USE ONLY UNDER IRB GUIDELINES.
laser therapy effects are biochemical and
not thermal and do not cause heating and thereby damage to
Four distinct effects
are known to occur when using low level laser therapy:
Growth factor response within cells and tissue as a
result of increased ATP and protein synthesis; Improved
cell proliferation; Change in cell membrane permeability to
Pain relief as a result of increased endorphin
release; Increased serotonin; Suppression of nociceptor
Strengthening the immune system response via
increasing levels of lymphocyte activity and through a newly
researched mechanism termed photomodulation of blood.
Acupuncture point stimulation.
Parameters for Use
parameters are important for clinicians to achieve the best
possible therapeutic effects when using low level laser.
A) Selection of the correct beneficial
B) The use of the correct Power levels
C) The consistent
application of the necessary amount of Energy
measured in Joules.
Another factor which has to be considered in laser
therapy is Pulsing Frequency.
Wavelength is measured in nanometers. It is set in the manufacturing of the laser diode in the probe and cannot be changed. Class
3B lasers are manufactured with wavelengths of between 600
and 1000 nm
Red Light Laser Probes
with Wavelengths between 620 and 675nm
absorbed by the mitochondria and therefore potentially
source of stimulation of a range of growth factors
- Red Light does not penetrate very effectively
below the skin surface and into the tissue below
- Red light is the best for wound healing or superficial
conditions but is not the most effective way to treat
Infrared (Invisible) Laser Probes with Wavelengths
between 780 and 950nm.
* Absorbed through the cell walls (acting differently between cells) and therefore cell response is more wavelength specific in the infrared range responding differently to different wavelengths
* More penetrative through the tissue, especially the 785-830nm range, therefore this range is selected for treatment through intact skin and pain relief
* Cluster probes with a range of wavelengths offer the best of both worlds to a clinician
How to Calculate the Necessary Energy Power (Watts) and Energy (Joules)
Power (watts or milliwatts) is the strength of the probe and is set at the factory. Clinicians need to know the power of the probe they are choosing to use and also have the probes regularly checked to ensure that they are running to full power. This check can be quite simply carried out by a special power meter. The simple formula as outlined above shows the calculation necessary to establish the amount of energy which we as clinicians are providing in each treatment. The relationship is Energy (as measured in Joules) = Power × Time. We provide detailed literature on the most commonly calculated procedures.
To create a response in the growth factor cells or to provide pain relief it is necessary to make sure that we are delivering sufficient energy Simply, to increase the energy being delivered by the probe you increase the time of treatment.
Pulsing rate equals the
number of times per second the laser turns on or off. Research
has demonstrated there are pulsing rate specific effects
with low level laser therapy. Concise details of optimal
pulsing frequencies and energy density requirements are
supplied with your laser equipment.
