Class IV laser therapy, also known as high-power or high-intensity laser therapy, is a type of medical treatment that uses a laser with higher power output compared to Class III or low-level laser therapy (LLLT). These lasers produce a greater amount of energy, which can penetrate deeper into tissues, including muscles and joints.

The therapeutic effects of Class IV laser therapy are based on the concept of photobiomodulation. When the laser light is absorbed by the body’s tissues, it can stimulate cellular processes, leading to various beneficial effects, such as:

  • Pain Relief: Laser therapy can help reduce pain and inflammation by promoting the release of endorphins and decreasing inflammatory markers.
  • Tissue Repair: The increased energy levels in cells can accelerate tissue repair and regeneration, aiding in wound healing and recovery from injuries.
  • Increased Blood Flow: Laser therapy can improve blood circulation, which can enhance oxygen and nutrient delivery to the tissues.
  • Reduced Muscle Spasms: By promoting relaxation of muscles, laser therapy can reduce muscle spasms and improve mobility.

Class IV laser therapy is used in various medical fields, including orthopaedics, sports medicine, chiropractic care, and rehabilitation. It is often used to treat conditions such as chronic pain, musculoskeletal injuries, arthritis, and neuropathic pain

The number of treatments needed depends on the nature of the condition being treated. For some acute conditions may be treated daily, particularly if they are accompanied by significant pain and 4-6 treatments may be sufficient.  More chronic problems respond better when treatments are received 2 to 3 times a week, requiring 6 to 12 (or more) treatments, tapering to once every week or two as improvement is seen.  Patients often describe the sensation during treatments as a soothing warmth or tingling.
