What is Laser Therapy ?

What is Laser Therapy ?

OUR LOW 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.

Low level laser therapy effects are biochemical and not thermal and do not cause heating and thereby damage to living tissue. Four distinct effects are known to occur when using low level laser therapy:

A)    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 calcium up-take.

B)     Pain relief as a result of increased endorphin release; Increased serotonin; Suppression of nociceptor action.  

C)    Strengthening the immune system response via increasing levels of lymphocyte activity and through a newly researched mechanism termed photomodulation of blood.

D)    Acupuncture point stimulation.

Parameters for Use

Three parameters are important for clinicians to achieve the best possible therapeutic effects when using low level laser.

A) Selection of the correct beneficial Wavelength

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

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

  • Readily absorbed by the mitochondria and therefore potentially stimulatory
  • Excellent 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 deeper injury

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.

Energy = Power × Time

Pulsing Rate

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.
