In what way does Class IV laser therapy affect inflammation?

Class IV laser therapy decreases inflammation primarily through the mechanism of promoting vasodilation. This process enhances blood flow to the treated area, allowing for increased delivery of oxygen and nutrients, which are essential for tissue repair and healing. The improved circulation also helps in the removal of inflammatory mediators and waste products from the site of injury or inflammation.

Vasodilation contributes to a reduction in edema and swelling, leading to a decrease in overall inflammatory levels. This response is part of the body’s natural healing process and is a key benefit of using laser therapy in various therapeutic applications. The ability of Class IV lasers to affect cellular function—stimulating cells to produce more energy (ATP) and releasing anti-inflammatory factors—further supports their role in reducing inflammation.

Other options suggest that laser therapy has no effect, significantly increases inflammation, or solely reduces pain without influencing inflammation. However, these interpretations overlook the established physiological effects of laser therapy and its broad therapeutic potential in managing inflammation effectively.
