In physical therapy, low-level lasers, often referred to as Class III or IV lasers, are commonly used. These lasers operate at wavelengths typically between 600 nm and 1000 nm. They are designed to penetrate tissues without causing damage and promote healing by reducing inflammation, alleviating pain, and enhancing tissue repair. Common types include:
1.Helium-Neon (HeNe) Lasers - Often used for superficial tissues.
2.Gallium-Aluminum-Arsenide (GaAlAs) Lasers - Frequently used for deeper tissue penetration.
3.Diode Lasers - Versatile and widely used in various therapeutic applications.
These lasers are utilized in treatments for conditions such as musculoskeletal pain, arthritis, and soft tissue injuries.
