Laser therapy is a medical treatment that uses focused light (laser) to treat various health conditions. The light is tuned to specific wavelengths, allowing it to interact with tissues precisely to reduce pain, inflammation, and accelerate tissue healing.
🧬 Origin of the Term
The word "LASER" is an acronym for:
Light Amplification by Stimulated Emission of Radiation
It refers to the process by which the laser light is generated.
🩺 How Does It Work?
Laser devices emit a concentrated beam of light that penetrates the skin or other tissues. This energy:
-
Stimulates cell regeneration
-
Improves blood circulation
-
Reduces inflammation
-
Relieves pain
-
Accelerates wound healing
🔬 Types of Laser Therapy:
-
Low-Level Laser Therapy (LLLT)
-
Also known as cold laser therapy
-
Used for: arthritis, sprains, tendonitis, back and neck pain
-
Non-invasive and painless
-
-
High-Intensity Laser Therapy
-
Used in surgical procedures
-
Can cut or destroy tissue (used in dermatology, oncology, eye surgery)
-
🏥 Common Medical Uses:
