What is Low Level
Laser Therapy (LLLT)?
LASER is an acronym for
Light Amplification by Stimulated
Emission of Radiation. Low Level Laser
Therapy or Cold Laser therapy is the application of
specific wavelengths of coherent laser light to injuries, skin, cells and tissues to initiate a healing response. Frequency is measured in Hertz (Hz) and can be delivered in some of the better lasers in combination with the light. A
lasers' wavelength is measured in nanometers (nm) and a lasers' power is measured in Milliwatts (mW).
Select laser light wavelengths supply the tissues at
a cellular level with photons and electrons.
Many Low Level Lasers exist under
the following names: cold laser, soft laser,
stimulating laser, resonating laser, healing laser, therapeutic laser, quantum laser
and so fourth. All of these Low Level Lasers are extremely safe
non-cutting, non-heat producing, gentle, therapeutic
What is the difference between Low
Level Laser Models, Stimulating Lasers and Resonating
Choosing a laser that will serve your
needs and fit into your budget is the key. All cold lasers or healing lasers are not created equal. You can not treat everything with one wavelength and expect great results. There are many factors to consider when investing in a laser and if you would like individualized help in making a wise choice for your particular needs, you can call one of our Laser Specialists for a free consultation at toll free 1-888-824-7558. This
website is a good place to educate yourself. One laser that
utilizes a single wavelength can be great for
numerous applications, but it will not successfully
treat all dis-eases and disorders. Owning multiple
lasers or a laser that combines various wavelengths
in one instrument provides for a greater treatment
range. The difference between Low Level Laser Models
boils down to the following 10 points:
Wavelength is the length of the
light wave and is measured in millimeters (mm) most
often expressed in nanometers (nm), which is 1/1000
of a millimeter. In the visible spectrum wavelength and color are basically
the same. Laser light in the
wavelength range of 600 - 700 nanometers (nm) results
in visible red light, which penetrates up to 1/2". In
the wavelength range of 701 - 1000 nm, invisible
infrared Laser Light results, with a penetration
depth up to 3". These two specific wavelength groups
of coherent laser light are the most commonly used.
They quickly help to activate the bodies innate
cellular communication system and positive immune,
enzyme and endorphin response. The most common
red light wavelengths are 630-670 nm, and for
infrared 780-905 nm. The 904-905 nm wavelength is the longest wavelength and delivers the deepest penetration, especially when combined with super pulsed laser technology.
Power density is the power output
of a laser or laser diode and is measured in
milliwatts (mW) or 1/1000 of a watt. Maintaining a
constant power density is critical in Low Level Laser
Therapy and is best achieved with a microprocessor or
Penetration is the
depth a laser beam will penetrate into the body,
dependant on the type of laser being used and the
frequency range it applies (See above). Deeper penetraion means greater delivery of photons to target tissue if the target tissue is deep enough or hard enough to require it.
Polarization is the
body's way of protecting itself against unpredictable
energy, such as electromagnetic pollution.
Polarization is also known as impedance of
resistance. It is triggered by Low Level Lasers
utilizing a high power density or by lasers that are
not controlled by a mini-computer, which ensures the
power density and frequency are constant. The success
of many Low Level Lasers is compromised by these two
factors and it is important to purchase a laser that
is driven by the exactness of a mini-computer for
operate between 10 mW and 500 mW of power. There are
many Low Level Lasers manufactured around the world
with many different power densities and wavelengths.
Most lasers manufactured today are of a single
wavelength powered by either AC or DC current. While
AC (alternating 110V current) is okay for stimulating
lasers, it is counter productive for Resonating
Lasers. Some of the best Stimulating Lasers at reasonable prices
are the AL500 Acupuncture Laser, the TerraQuant Pro series lasers, the MedX Laser 200mW probe, the Omega XP laser to name a few.
Lasers emit subtle energy capable of
relaxing muscles, relieving pain, healing wounds, and
with the proper combination of frequencies,
delivering energy into the organs and glands.
Resonating Lasers operate at approximately 5 mW of power
per diode in order to prevent polarization and to
enhance energy delivery. The more
laser diodes a Resonating Laser has, the larger the
area that can be treated at one time. A good
Resonating Laser is powered by a mini-computer, which
allows for precise power density output. The mini-computer can also control
the precise wavelength emitted, deliver therapeutic frequencies and allow for a series
of specifically selected wave forms. The best resonating laser out there is the Scalar Wave Laser, which delivers energy to the body from a cluster of 36 diodes (5mW each) in 3 different wavelengths. It is also available with optional stimulating probes in 3 different wavelengths with power outputs of 100mW each.
Frequency is the term used to explain
the vibration of energy in all things. Everything we
know and understand has a vibrational frequency,
which is measured in Hertz (Hz). Royal Rife, Paul Nogier and Jack
Swartz were all pioneers who dedicated their lives to discovering frequency medicine. Through great trial and error and with the help of powerful microscopes Mr. Rife found the
frequencies that correspond to such things as:
various diseases, bacteria, viruses and other
disorders. Mr. Nogier discovered a detailed map of the entire body within the ear and specific frequencies to heal with. In diagnostic medicine, frequencies are
well known: EKG's for the heart, EEG's for the brain,
and MRI's for injured cells.
area" of a laser is the diameter of the area
that can be treated at one time. This depends on the
type of laser being used and the number of laser
diodes the laser is utilizing for treatment. Most
common Stimulating Lasers utilize 1-3 laser diodes
focused upon a single point about 3mm (1/4 inch). The
3mm spot area is surrounded by a larger diameter,
which is the immediate effective spread of the Laser
energy. The "spread area" is approximately 1/2" (10mm in
diameter). A few other lasers utilize more laser
diodes to cover a larger area.
is the term used to define the amount of energy
delivered by one watt of power in one second. The
formula for calculating joules is output x time
÷ area and is critical in determining if a
laser is resonating or stimulating.
We are complex spiritual and energetic beings.
Disease or dis-ease and illness are the result of
imbalances in our unique energy systems, which
compromises our immune, circulatory and muscular
skeletal systems. Sickness is not necessarily caused
by germs, bacteria and viruses, although these "bugs"
are opportunists and they do interfere with our
health when our inner terrain is compromised. When
the immune system is inactive, overworked or
suppressed and the cells are weak and unable to
function at peak capacity, dis-ease and aging

irradiation works to support the natural healing
process of the body because it:
Donates photons and electrons to the
injured tissues and weak cells of the body, which
supports the production of ATP (energy) that is
needed by cells to carry out their duties.

production of natural pain killer endorphins.

Laser irradiation of tissue cultures of a
mammalian cell has been shown to result in a change
in membrane permeability, increased ATP levels and
increased DNA production. The photons picked up by
the cell membrane result in improved membrane
stability and increased activity of the ATP dependent
Na/K pump. Because cell metabolism is influenced by
Na/K movement across the membrane, increasing the
gradient will affect the flow of ions and hence the
overall metabolism of the cell.
Are Low Level Lasers Proven
Low Level Laser Therapy is being used as a
successful treatment option for countless, pain,
inflammation, dental, burn and illness conditions all
over the world. Low Level Lasers have been used for
over 30 years in many countries as therapeutic energy
to bring about favorable biological effects in
people, plants and animals. Unlike many therapies and
drugs that just treat symptoms, Low Level Laser
Therapy (LLLT) has the ability to actually promote
and enhance healing. LLLT is the future of medicine
and is a modality that is rapidly growing in
popularity throughout the world. In the last few
years Laser Therapy in North America has been
steadilly and exponentially increasing and the FDA
has recently cleared multiple laser and LED devices
for treatment of a variety of medical conditions
including: carpal tunnel syndrome, cervical neck
pain, low back pain, joint pain, generalized muscle
pain and acceleration of wound healing. Technical
light therapy is being used by Governmental agencies
such as NASA for treating medical conditions in space
applications. The U.S. Olympic training facilities
have just released statements of endorsement for
Laser Therapy for athletes. The growing acceptance of
LLLT in mainstream medicine is yet another indication
of the medical efficacy of this highly effective
treatment modality, which is proving to be not only a
viable, but often a superior treatment option.
Over 75 Trillion cells in a human body all need
electrons to communicate with each other. Laser light
delivers these required electrons directly to the
cells and enhances both their ability to communicate
with each other and their ability to produce ATP
(energy), which they require for optimal functioning.
Additionally LLLT causes the release of healing
enzymes and the production of endorphins, which are
natural pain killers.
Are Low Level Lasers Safe?
The answer is a resounding YES. When Low Level
Lasers are used correctly, they are very safe. The
most important safety regulation is to avoid pointing
a laser at the eye. Stimulating lasers have a
particularly powerful beam and can cause harm to the
retina. Do not point them directly at a fetus during
pregnancy, or directly over a cancer. Cold lasers
have been used successfuly for over 30 years with no
reported incidences of anyone being injured.
Low Level Laser Therapy has been proven completely
safe in over 3000 worldwide studies. To date there
are no known reports of anyone being harmed from a
low level laser.
How do you use Low Level Lasers?
Low Level Lasers are used by applying the laser
light at a right angle, directly over the area or
condition of concern, and leaving it there until the
recommended time has elapsed or number of Joules is absorbed. Later in
this document you will learn about utilizing lasers
for the treatment of acupuncture points and the
number of Joules required per point. Both Resonating
Lasers and Stimulating Lasers can be used for
acu-point, trigger-point and myofascial-point
treatment. While the Scalar Wave Laser is a Resonating Laser, if
it is used for longer periods of time on a single
point it will also provide the same stimulating
results as a Stimulating Laser, however a Stimulating
Laser cannot achieve the same effects of a Resonating
Low Level Laser Therapy
The Laser treatment may be given with a Resonating
Laser or a probe style laser. While a Resonating
Laser may take longer to treat a point, it will also
treat a much larger area. Stimulating probe style
lasers typically provide spot treatment of
approximately 3mm (1/4 inch). The 3mm spot area is
surrounded by a larger area, which is the immediate
effective spread of the Laser energy. The "spread
area" in this instance would be approximately 10mm (3/4") in
diameter. The laser should be applied at right angles
to the skin, and in contact with the skin in order to avoid loss of light energy
due to reflection or deflection. The laser can be
applied over light clothing or wound dressings,
however it does not perform well with black or thick
Laser Point Treatment:
The following protocols are for Resonating or
"point treatment" as apposed to scanning. "Point
treatment" means to treat any given point on the
surface tissue, with the selected dosage. Optionally,
some therapists may choose to use the technique of
scanning, which involves moving the laser with the
tip as close to the tissue as possible, backwards and
forwards over the selected area of treatment. With
"scanning" the movement should be very slow and
steady. Imaginary lines should be traced with spacing
of 5-10mm between the lines and sometimes crisscross
lines are also applied. This results in a general
"bathing" technique, which can be used to treat
larger target areas. However, with this technique it
is important to make sure that adequate time is spent
in doing this to ensure that enough Joules are
absorbed by the tissue.
Frequency of Treatment Sessions:
In general, treat every 2-3 days for 4-5
treatments. Follow this with one treatment per week
until the issue is resolved. Some conditions,
including long term chronic conditions may need "tune
up" treatment every 4-6 weeks, or as required.
Never look directly at the Laser
aperture or the light. Protect your eyes. Infrared
laser light is invisible, so use extra caution with
A maximum of 50 Joules per adult for
total treatment dosage and 25 Joules for a child is
recommended per session.
Overuse of a laser is generally just
a waste of time and will cause diminishing returns,
reducing the benefits, but you will not make a cell
worse than when you started.
If pain gets worse due to treatment,
which rarely occurs, do not be alarmed. The laser has
increased the circulation and caused the release of
toxins, which sometimes causes some early discomfort.
It is an indication of tissue reactivity and precedes
Low Level Laser Therapy (LLLT) is
generally considered complimentary and can be used
with adjunctive treatments. In general it is a good
idea when combining LLLT with other modalities to do
cooling techniques prior to LLLT and warming
techniques after LLLT.
Patients with acute conditions will
frequently see beneficial effects almost immediately.
Patients with chronic conditions may find that a
slightly longer treatment regime is required before
effects are obvious.
