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

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.

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.

The photobiomodulation can have both (i) Photobiostimulative effect (ii) Photobioinhibitive effectThe 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.

LASER MECHANISM OF ACTION:-

LASER THERAPY:-

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 probeTo achieve and to get good effectiveness from the laser therapy following parameters:-

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).

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.

we will have the demonstration of the laser therapy MODEL: DIGI LASER- Pro Manufactured by BHARAT MEDICAL SYSTEMS Chennai

Now move the cursor to time place by using down key and press select key and press up key to increase up to decided time(6 to 8 min). After selecting the decided time press select key.

Now, by using up key move the cursor to frequency place, press select key and press up key increase the frequency up to 5000Hz for superficial/acute pain. Increase the frequency up to 10,000Hz for deep/chronic pain. When your increasing the frequency(right side of the frequency), corresponding power, energy and energy density will be calculated and displaying by the machine automatically.

When your increasing the pulsed% energy and energy density will be calculated and displaying by the machine automatically.

By adjusting any one or two parameters (Frequency, pulsed%) you will be getting decided energy with in the decided time.

By adjusting the area we will be getting corresponding energy density per cm.

After selecting the parameter you will select key. The display will asking Press Select to save.

If you want to save the selected parameters press select key(see user memory) if you dont want to save the parameters press START key to start therapy.Now the display will be

In right side of the display Run Time will be displaying in ZOOMED number.The timer will be coming down every minutes and when its reads 00 the output will cut off.

Save procedure:-If you want to save the selected parameters press SELECT key display will be.

By default the select bar will be in page No:1 if all are engaged with patient name or Disease name then move to page No:02, 03 up to find the empty memory (1 to 10 pages) by using up and down key. If you find EMPTY memory in any page press SELECT key the select bar will be moving to 1st memory of the page. Now, move the select bar to the required memory by using up and down key and press select. now you can write the first letter of the patient name by using up and down key when you are pressing up key the 1st letter will be changing to F,G,H,I,J,..Z,A,B,. If you are pressing down key letter will be changing to,D,C,B,A,Z,Y,,B,A,

After selecting the 1st letter then press start key. Now the cursor is move to the 2nd letter follow the same procedure to select the required letter, likewise you can type the five letters and used stored the data in the patient name "start key is used to move the cursor towards forward direction and MENU key is used to move the cursor in reverse direction.After writing the patient name select now the data stored in the particular memory (page no. 2 and Sl.No:18) in the particular patient name (ARUNKUMAR) and therapy also start likewise 100 patient name or disease name can be stored.

When the patient come for next treatment you can go to the memory select the name ARUNKUMAR.

If you find the suitable pain condition in the display by using up and down key move the select bar to the required condition press select key.Now, in preprogrammed mode stored parameters are not satisfied you can change the parameters by using select, up and down key.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 reads00 the output will cutoff.

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).

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.

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 datas 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 ).

AREA OF TREATMENT:- (POINTED)If pain area (Treatment area) is pointed i.e. 1 cm . 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 1cm because the area is pointed. Now, you can notice energy and energy density will be same unit.

WIDER AREA:Example:- Approximately treatment area is 4cm .If you are decide 3J per cm2. So, total energy will be 4x3=12 Jules for 4cm So, total energy is required 12J to treatment the area of 4cm .And keep the area in 4cm .So, total energy, energy density/cm2 will be calculated and displaying by the machine automatically.

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(90angle) 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.

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.
