Laser Therapy

WHAT IS LASER THERAPY?

Light Amplification by Stimulated Emission of Radiation is referred to as L.A.S.E.R. Low-intensity laser light is used in laser therapy to treat pain brought on by soft tissue damage. It makes tissue repair easier and gets cell function back to normal. Experts use it to relieve pain and repair wounds. Compared to other types of laser therapy, like those used to coagulate tissues and eliminate malignancies, the level of light is fairly modest.

High power lasers

Due to the heat response they produce, high-power lasers are also referred to as hot lasers. They are employed in surgical procedures to coagulate tissues, cut through tissue, and eliminate malignancies.

Low power lasers

The Arndt-Schulz principle, which asserts that if a stimulus is too faint, no effect is apparent, governs how low power lasers operate. The term “photobiomodulation,” which is also used to refer to increased stimulation and optimal dose, is used to treat pain and promote wound healing. However, further dose increases have the unfavourable effect of decreasing the effect, and further dose increases have the unfavourable effect of inhibiting stimulation. Low laser is a non-invasive, painless procedure. It possesses the characteristics of coherence, collimation, and monochromaticity (all beams are the same colour and parallel to one another over great distances) (all the light waves are in phase both spatially and temporally).

EFFECTS OF LASER THERAPY

In general, this treatment is non-invasive, safe, and reliable. The laser device will touch your skin, but the process is painless and you won’t feel any vibrations or heat. The skin layers are penetrated by the non-thermal photons of light that are released by the laser. After the light has penetrated the skin’s layers and reached the target location. After the body tissue absorbs the light, a number of biological processes begin that speed up intracellular metabolism, promote tissue repair, reduce pain and inflammation, and shorten the overall healing time.

• Reduce pain 
•  Increases ATP (Adenosine Triphosphate) which accelerates the repair process of the cell. Some molecules that increase inflammation are reduced and beneficial antioxidants are increased.
• Faster wound healing. Laser Therapy is effective on open wounds also.
• Recovery from nerve injury Reduces aches and pains by decreasing nerve sensitivity.
• It reduces the formation of Fibrous/Scar tissue. It also improves the vascular activity in the body.
• Promotes bone and cartilage formation

Most commonly used lasers

Helium-neon

A pressurised tube filled with helium gas and neon is employed in this laser. This produces a laser with a wavelength of 632.8 nm in the red region of the electromagnetic spectrum.

Gallium arsenide

It produces an infrared invisible laser with a wavelength of 904 nm using a diode. Semiconductor silicon is sliced and stacked to form diode lasers. At the intersection of the two surfaces, lasing action is created by applying an electrical source to each side. The surfaces produce coherent light by serving as surfaces that partially reflect light. This laser is delivered in pulsed form due to the heat it generates.

APPLICATION OF LASER THERAPY.

Laser therapy, also known as phototherapy or low-level laser therapy (LLLT), is a medical treatment that uses low-level lasers or light-emitting diodes (LEDs) to stimulate cells and tissues. The therapy is non-invasive and painless and is used to ‘treat a wide range of conditions, including:

1 Pain management: Laser therapy has been shown to be effective in reducing pain associated with conditions such as arthritis, back pain, and neck pain.

2 Wound healing: Laser therapy can speed up the healing process of wounds  and reduce scarring by promoting the production of ATP, a molecule that provides energy to cells.

3 Skin conditions: Laser therapy can be used to treat skin conditions such as acne, rosacea, and eczema by reducing inflammation and promoting cell renewal.

4 Hair loss: Low-level laser therapy has been shown to be effective in treating hair loss by increasing blood flow to the scalp and promoting hair growth.

5 Neurological conditions: Laser therapy has been used to treat neurological conditions such as depression, anxiety, and migraines by increasing the production  of neurotransmitters in the brain.

6 Rehabilitation: Laser therapy is often used in physical rehabilitation to reduce inflammation and swelling, improve circulation, and accelerate the healing process.

7 Sports injuries: Laser therapy has been shown to be effective in treating sports injuries such as sprains, strains, and tendinitis by reducing pain and swelling and promoting healing.

In conclusion, laser therapy is a versatile and effective treatment for a wide range of conditions and has been shown to have few side effects. However, as with any medical treatment, it is important to consult a healthcare professional to determine if laser therapy is appropriate for your specific needs.
