Class 4 Laser Therapy at Portland Physical Therapy and Fitness
Class 4 laser therapy is a powerful, non-invasive treatment that supports faster healing, reduces pain, and restores function, making it a valuable tool for physical therapy and recovery. At Portland Physical Therapy and Fitness, we use class four therapeutic laser technology to help accelerate your body’s natural repair process at the cellular level. Whether you’re dealing with a recent injury, chronic inflammation, or post-surgical scarring, laser therapy can promote healing where your body needs it most. By increasing blood flow, stimulating tissue regeneration, and reducing inflammation, this treatment helps you move better, recover quicker, and return to the activities you love.

What is Class 4 Laser Therapy?
Class 4 laser therapy (sometimes referred to as class four therapeutic laser treatment) uses specific wavelengths of light to target damaged or inflamed tissues. This light energy penetrates deep into muscles, tendons, and joints, stimulating biological processes at the cellular level.
Think of it like this: plants need sunlight to grow—your cells, when injured or inflamed, benefit from targeted light exposure in much the same way. The high-powered laser boosts cellular metabolism, helping your body heal faster and more efficiently.
Unlike passive treatments, class four laser therapy supports real, active recovery without relying on medication or invasive procedures. The laser works best during the early stages of healing and is often used alongside stretching, hands-on therapy, or exercises to help your body recover and feel better faster.
What is Class 4 Laser Therapy Used For?
Class 4 laser therapy is highly versatile and can be used to treat a wide range of conditions. At our clinic, we primarily use it to support healing from:
- Acute injuries – including sprains, strains, and soft tissue damage
- Scar tissue – especially hypertrophic scarring after surgery that limits mobility
- Arthritis and joint degeneration – for reducing inflammation and easing stiffness
- Chronic pain – such as lingering pain from overuse or long-standing injuries
- Post-operative recovery – to support tissue regeneration and reduce swelling
- Localized inflammation – to address swelling, redness, and tenderness early in the healing process
Whether you’re recovering from a recent injury, managing a chronic condition, or simply trying to get back to your favorite activities, class four laser therapy can be a valuable part of your recovery plan.
How Does Class 4 Laser Therapy Work?
At the core, class 4 laser therapy works by delivering concentrated light energy—in the form of specific wavelengths—into the tissues that need healing. This energy is absorbed by the cells and converted into adenosine triphosphate (ATP), the fuel that powers cellular activity.
Increased ATP production leads to:
- Faster cell repair and regeneration
- Reduced inflammation
- Enhanced circulation
- Decreased muscle spasms
- Stimulated activity of healing cells like fibroblasts and macrophages
- Improved tissue oxygenation and nutrient delivery
You might not see the laser working, but beneath the surface, your body is engaging in faster, more efficient healing.
According to research published in the NCBI, class IV lasers significantly influence biological tissues through mechanisms like photobiomodulation, which stimulates mitochondrial function, cellular replication, and tissue regeneration.
Benefits and Side Effects
Benefits of Class Four Therapeutic Laser Therapy
- Pain Reduction – One of the most immediate and noticeable effects. Many patients experience pain relief within the first few sessions.
- Faster Recovery – From injuries, surgery, or overuse, laser therapy helps your body bounce back more quickly.
- Improved Mobility – Especially helpful for patients with joint or muscle stiffness due to inflammation or scarring.
- Minimal Downtime – Sessions are quick, painless, and non-invasive. You can resume daily activity afterward.
- Complementary to Other Treatments – Easily integrated into a broader physical therapy plan, including manual therapy and corrective exercise.
Are There Any Side Effects?
Class 4 laser therapy is widely considered safe when administered by trained professionals. Side effects are rare and typically mild, including:
- Temporary warmth or redness at the application site
- Tingling or light sensitivity in some cases
At Portland Physical Therapy and Fitness, we use evidence-based protocols and adjust treatment parameters for each patient to ensure comfort and effectiveness.
Class 4 Laser Therapy Treatment Plan at Portland Physical Therapy and Fitness
At our clinic, class 4 laser therapy is never a standalone solution—it’s integrated thoughtfully into a broader rehabilitation strategy.
Typically, we’ll use the laser in the early stages of your treatment, especially when:
- Pain levels are high
- Inflammation is active
- Scar tissue is limiting movement
- The goal is to jumpstart the healing process
You might receive laser therapy once a week during the initial phase, often for the first 2–4 weeks, depending on your condition. As your symptoms improve and we transition to more active therapies like strengthening and mobility training, laser use usually tapers off or is discontinued.
Sessions are short—usually 5 to 15 minutes—and are often paired with hands-on manual therapy or movement work during the same appointment.
This “early-phase” emphasis allows us to set the stage for long-term healing without relying solely on pain management.
Is Class Four Laser Therapy Right for You?
If you’re experiencing any of the following, you may be a great candidate for class four therapeutic laser treatment:
- New or recent soft tissue injuries
- Persistent joint inflammation
- Post-surgical stiffness or scarring
- Acute or chronic pain limiting daily function
- Delayed tissue healing
- Athletic injuries affecting training or performance
Laser therapy is especially valuable for individuals who want to stay active during recovery and minimize dependence on pain medications or injections.
