How should the laser be positioned in relation to the treatment area?

Positioning the laser perpendicular to the skin is essential for effective treatment outcomes. When the laser is held perpendicular, it ensures optimal energy delivery to the target tissue. This alignment minimizes any scattering of the laser light, allowing for a more focused and uniform penetration of the laser energy. This is crucial in achieving the desired therapeutic effects, whether the goal is to reduce inflammation, promote wound healing, or alleviate pain.

Holding the laser at an angle, such as at a 45-degree angle, or parallel to the skin can lead to uneven treatment, decreased efficacy, and potential complications. When the laser is not directed straight onto the skin, some areas may receive less energy than intended, resulting in ineffective treatment.

Additionally, maintaining an appropriate distance—while important—should not replace proper angling of the laser beam. Therefore, positioning the laser perpendicular to the skin is the best practice for maximizing the benefits of Class IV laser therapy.
