Whether you’re rehabbing from a sprain, managing a nagging low back issue, or looking to optimize recovery time, Class IV laser therapy offers a safe, non-invasive way to get you back to peak performance.
How does it work?
Laser therapy is a non-invasive treatment that uses specific wavelengths of light to stimulate cellular healing, reduce pain, and accelerate recovery in both acute and chronic conditions. This process of using light to stimulate the body’s natural healing processes is known as photobiomodulation. Therapeutic lasers are categorized into four different classes based on their power output and depth of tissue penetration. These factors determine their therapeutic effectiveness and safety levels. Therapeutic lasers range from low-level Class I–III devices to high-powered Class IV systems. Lower-level lasers primarily target surface tissues and are often used for mild pain modulation, while higher-powered Class IV lasers penetrate deeper to accelerate repair, reduce inflammation, and enhance circulation.
Across all classes, laser therapy works by energizing cells, promoting faster recovery, reducing pain, and improving overall tissue function—making it a versatile tool in both acute injury management and long-term rehabilitation.
What Makes Class IV Laser Different?
Class I, II, and most Class III lasers can be purchased by the public, but the higher-powered Class III and Class IV lasers must be used under professional supervision. Class IV lasers are a special class of therapeutic lasers because of the substantially increased power output allowing the light energy to penetrate deeper into muscles, tendons, and joints. This higher intensity enables faster tissue healing, greater pain reduction, and shorter treatment times.
What are the benefits?
- Boosts Cellular Energy (Increase ATP Production)
Laser light stimulates the mitochondria — the energy-producing engines of your cells — to generate more ATP. This added energy fuels faster repair and regeneration of damaged tissue. - Reduces Inflammation and Swelling
The light energy dilates blood vessels and increases lymphatic drainage, helping flush out inflammation and reduce swelling around injured areas — crucial for both acute and chronic conditions. - Decreases Pain
Laser therapy helps reduce pain by modulating nerve activity and stimulating the release of endorphins — your body’s natural pain relievers. Many patients notice pain relief immediately after treatment. - Improves Circulation and Oxygen Deliver
Class IV laser therapy increases blood flow to the targeted area, delivering more oxygen and nutrients to the tissue and supporting a quicker recovery process. - Accelerates Tissue Repair
By stimulating collagen production and fibroblast activity, Class IV lasers promote faster healing in muscles, tendons, and ligaments — helping athletes return to training sooner and with greater confidence.
Injuries That Benefit Most from Laser Therapy
Class IV laser therapy is used to treat a wide range of acute and chronic musculoskeletal injuries, including:
- Ligament sprains (ankle)
- Muscle strains (hamstring)
- Acute low back pain
- Neck pain
- Headaches/migraines
- Tendinopathies (shoulder, Achilles, or patellar)
- Rotator cuff injuries
- Plantar fasciitis
- IT band syndrome
- Hip and knee pain
- Shin splints
- Joint inflammation or arthritis
- Post-surgical soft tissue healing
What to expect during treatment
Each Class IV laser session lasts about 5–10 minutes. You’ll wear protective goggles while a trained clinician applies the laser handpiece to the treatment area. You’ll feel a gentle, soothing warmth as the light energy penetrates your tissues. Most patients find the treatment relaxing — many even describe it as a pleasant warmth. Once the session is over you can immediately return to normal activities as tolerated. Most treatment plans include 4–8 sessions, spaced out over several weeks, depending on the condition and its severity.
