Low-level laser therapy

From WikiMD's Wellness Encyclopedia

Low-Level Laser Therapy (LLLT), also known as cold laser therapy, is a form of phototherapy that uses low-level (low-power) lasers or light-emitting diodes to alter cellular function.

History[edit | edit source]

The use of low-level laser therapy dates back to the 1960s, when Endre Mester, a Hungarian physician, first discovered its biological effects during an experiment on mice.

Mechanism of Action[edit | edit source]

LLLT works by emitting photons, which are absorbed by the mitochondria and cell membranes. This leads to an elevated production of ATP, increased DNA and RNA synthesis, and improved cell proliferation. The overall effect is enhanced cell repair and functionality.

Applications[edit | edit source]

Low-level laser therapy has been used in various medical fields, including dentistry, physiotherapy, and dermatology. It is used to treat a variety of conditions such as:

  • Pain: LLLT is used to manage both acute and chronic pain.
  • Wounds: It accelerates tissue repair and cell growth.
  • Inflammatory conditions: LLLT reduces inflammation by inhibiting inflammatory cells.

Safety and Efficacy[edit | edit source]

While LLLT is generally considered safe, its effectiveness varies depending on the condition being treated, the power and type of the laser, and the duration of treatment. More research is needed to establish optimal treatment protocols.
