1. LASER THERAPY
BHARAT MEDICAL SYSTEMS
CHENNAI, INDIA
(DIGI LASER – Pro Demonstration)
2. LASER THERAPY:-
LASER Therapy Acronym is LIGHT AMPLIFICATION
STIMULATED EMISSION of RADIATION Therapy.
Laser therapy treatment helps reduce pain and inflammation and
enhances tissue healing – both in hard and soft tissues , including
muscles , ligaments , and even bones.
It increases oxygenation of tissues and allows injured or damaged
cells to absorb photons of light , which speeds healing .
Laser therapy can be helpful for acute injuries, such as strains ,
sprains , shoulder injuries
3. Low-level laser therapy (LLLT) is a pain-free, non-invasive,
affordable tool used by physical therapists
throughout the healing process that is becoming more
prevalent in PT practices nationwide.
Low-level cold lasers are absorbed into the skin to
increase cellular activity in tissues, which can bring
healing to injured areas.
4. Laser is a Monochromatic coherent beam produces “speckles”
emission of high power density which can cause a local heating
of inhomogeneous tissues.
Laser Therapy works on the principle of inducing a biological
response through energy transfer, in that the photonic energy
delivered in to the tissue by the laser modulate the biological
processes within the tissue. So it is called
PHOTOBIOMODULATION.
5. The photobiomodulation can have both
(i) Photobiostimulative effect
(ii) Photobioinhibitive effect
The Laser Therapy effectiveness based on the principle of ”The
Arndt-Schultz law” of biomodulation.
The Arndt-Schultz law of Biomodulation infers that low
dosage of photonic energy will stimulate the biological
process in the tissue the higher dosage of photonic energy will
inhibit the biological process in the tissue.
10. To get good and effectiveness result of the laser therapy.
The following parameters are very important
1.Dosage of photonic energy
2.Duration of the Treatment
3.Angle of Laser beam penetration.
4.Wavelenght of the probe
To achieve and to get good effectiveness from the laser
therapy following parameters:-
11. 1. variable frequency from 200 Hz to 10,000 Hz to vary the power.
2. Variable power from 2 mw to 100 mw to vary the energy.
Energy=watt x time.
3.Variable pulse ratio 10%,20% up to 100% to vary the energy.
4.Variable treatment time
5.Variable treatment area in square centimeter
6.Automatic calculation of power
7.Automatic calculation of energy
8.Automatic calculation of energy density/ cm2
9.Sensor for IR Laser check. Because IR beam is invisible.
Energy= Power (mw) X Time(mts)
(According to the area of the pain applied energy will be varying so get
decidable energy we have to vary the power so that we can select low
dosages of energy as per Arndt-Schultz law of Bio modulation).
12. The apparatus should have a two different wavelength of the
probe
1.RED probe – visible RED Laser probe 650nm and 100mw power
for superficial tissue penetration
2.Infrared IR Probe- Invisible Red Laser probe 950nm and 100 mw
power for deep tissue penetration.
The tip of the probe should be covered with plastic cling film, in
order to reduce the likelihood of cross contamination 0r infection.
Laser therapy can followed by Cryotherapy to increase the depth
of penetration or heat therapies and various creams and lotions
can be applied after laser therapy.
ENERGY SELECTION:-
In general superficial/acute pain 1 to 5 J/cm2 within 6 to 8 min.
Deep/chronic pain 8 to 12J/cm2 within 6 to 8 min.
If pain area is wider then multiply the energy.
13. we will have the demonstration of the laser therapy

In preprogrammed mode the stored parameters are
satisfied then press ”START” key, no need of saving the
data because it is already stored, so press once again
“START” to start therapy.
The timer will be coming down every minutes and when
its reads”00” the output will cutoff.
30. The above same procedure to follow in the
preprogrammed.
When you are selecting the preprogrammed, no need of
saving the data in user memory because it is
permanently saved in preprogrammed.
When you are selecting the parameters(data) by your
own, if you want to treat the same patient in future,
you can save the data's in the user memory(100 patient
can be stored).
31. USER MEMORY:
When your selecting the user memory.
Now, if you want to treat
the patient “ARUNKUMAR”.
Scroll the page number by
using up and down key
up to the page displaying
the name “ARUNKUMAR”.
Once you find the “ARUNKUMAR” select the page No.
and select the name “ARUNKUMAR”.
32. Now, if you want to save the new data's in the same user
memory you can save otherwise, no, need to save the data
because already data’s are stored in the user memory.
Then press “START” key the display will be displaying the
“PRESS SELECT TO SAVE ” in bottom of the display.
Now, press “START” key to start therapy.
The timer will be coming down every minutes and when its
reads “00” the output will cut off.
If any particular patient treatment course is over you can
overwrite the new data, new patient name, and store in the
same memory, now old name and data will be erased and
new data's and new name will be stored in the memory,
EPROM, (Erasable programmable read only memory ).
33. AREA OF TREATMENT:- (POINTED)
If pain area (Treatment area) is pointed i.e. 1 cm² . as
per the Arndt-Schultz law.
And after examination of the patient select the energy
with in 1 to 5 J with in the decided treatment time 6 to
8 mts keep the area in 1cm² because the area is pointed.
Now, you can notice energy and energy density will be
same unit.
34. WIDER AREA:
Example:- Approximately treatment area is 4cm² .If
you are decide 3J per cm2. So, total energy will be
4x3=12 Jules for 4cm²
So, total energy is required 12J to treatment the area of
4cm² .
And keep the area in 4cm² .So, total energy, energy
density/cm2 will be calculated and displaying by the
machine automatically.
35. Manual scanning:-
For wider area treatment apply the jelly/oil/cream/ lotion
on the tip of the probe to maximize irradiance at the target
tissue and move the probe in contact with patient body
perpendicular(90˚angle) to the tissue in clockwise direction
in uniform speed at the pain area.
Cluster probe:-
Multi diode cluster probes may not be effectiveness because
it contain multiple wavelengths of the diodes (each diode
will not be same wavelength) which can lead to a
degradation of the effectiveness of laser therapy.
(Karu,1998)
So manual scanning method is advisable and suitable for
the wider area application.
36. Open wounds treatment:-
When treating the open wounds the probe should
be held slightly away from the tissue surface,
whilst still maintaining a 90˚ angle. when you treat
next patient please clean the tip of the probe.
