Class 4 Laser Treatment
Mechanism of Class IV Laser Therapy
Class IV lasers use higher wavelengths, usually between 800 and 1,000 nanometers, which reach deeper layers of muscle, fascia, and joint tissue.
Class 4 Laser Therapy Benefits
- Reduce pain and swelling
- Improved range of motion.
- Increases tissue regeneration which is why you heal faster
- Accelerates soft tissue and bone repair
- Improve nerve regeneration & function
- Increase cell metabolism, enzymatic responses, collagen production, and promote angiogenesis (the creation of new blood vessels).
Therapeutic Laser Biological Effects:
- Rapid Cell Growth — Laser light accelerates cellular reproduction and growth.
- Faster Wound Healing — Laser light stimulates fibroblast development and accelerates collagen synthesis in damaged tissue.
- Increased Metabolic Activity — Higher outputs of specific enzymes, greater oxygen and food particle loads for blood cells and thus greater production of the basic food source for cells, Adenosine Triphosphate (ATP).
- Reduced Fibrous Tissue Formation — Laser light reduces the formation of scar tissue following tissue damage from cuts, scratches, burns or post-surgery.
- Anti-Inflammatory Action — Laser light reduces swelling caused by bruising or inflammation of joints to give enhanced joint mobility.
- Increased Vascular Activity — Laser light induces temporary vasodilation increasing blood flow to damaged areas.
- Stimulated Nerve Function — Slow recovery of nerve function in damaged tissue can result in “dead” limbs or numb areas. Laser light speeds the process of nerve cell reconnection to bring the numb areas back to life
For over 20 years, clinicians found that laser therapy for pain treats a variety of chronic conditions including:

ABSTRACT:
About 20-50 % of patients with diabetes and about 60 % of those with diabetic neuropathy develop neuropathic pain, which is characterized by tingling, burning, sharp, shooting, or stabbing sensations, and even electric shock-like sensations. Painful diabetic neuropathy can significantly affect the quality of life of patients with diabetes, the ability to perform daily activities and negatively affect mood. According to the 2021 consensus of an international panel of experts regarding the treatment of painful distal symmetric polyneuropathy, non-pharmacological forms of treatment should also be considered due to unsatisfactory pharmacotherapy. A number of studies have demonstrated the role of photobiomodulation as a non-pharmacological method of treating painful diabetic neuropathy.
The purpose of this placebo-controlled, longitudinal study was to investigate the effect of high-energy MLS-laser therapy on neuropathic pain.
Material and methods: A total of 69 cases of patients with type 2 diabetes and painful diabetic neuropathy of the lower extremities were followed, divided into two groups: an experimental - 41 patients received high-energy laser radiation and a control (placebo) group - 28 patients, with a "mock" laser treatment. For objectification of pain, the Bulgarian version of the short form of the McGill pain questionnaire, version SF-MPQ-2, which includes the visual analog scale (VAS), was used. Comparisons between groups were performed with parametric or non parametric tests depending on the distribution of the variables, the number of the compared groups and the study pre test – post test design.
Results: The pain index, reported by the McGill questionnaire, in the experimental group, decreased by - 63.2 % at the end of the nine-day treatment and by - 56.1 % at the 90th day after the start of treatment compared to the value before therapy. In the control group, there was a minimal change at the end of treatment (day 21), which did not persist until the end of the observation period (day 90).
Conclusions: MLS laser therapy significantly increases the pain threshold and should be considered a safe, non-pharmacological adjunct to standard therapy in patients with painful diabetic peripheral neuropathy.
