Harnessing the Power of Photobiomodulation: A Clinician’s Guide to Laser Therapy

In recent years, laser therapy—or more accurately, photobiomodulation therapy (PBM)—has moved from the periphery of rehabilitation medicine into the mainstream. With growing evidence supporting its effectiveness for pain relief, inflammation reduction, and tissue repair, clinicians across physiotherapy, chiropractic, and sports medicine are integrating this powerful modality into daily practice.

But what exactly is PBM, and why should you consider it for your clinic?

What is Photobiomodulation Therapy?

PBM is a form of light therapy that uses non-ionising light sources, such as lasers and LEDs, in the visible and near-infrared spectrum. When absorbed by cellular structures (most notably cytochrome c oxidase in mitochondria), this light energy stimulates a cascade of biological responses:

• Enhanced ATP production (more cellular energy)
• Nitric oxide release (improving circulation and tissue oxygenation)
• Reactive oxygen species regulation (modulating inflammation)

Together, these effects can:
✅ Reduce pain and inflammation
✅ Promote wound healing and tissue regeneration
✅ Support faster recovery after injury or surgery

Why Laser Power Matters

Not all lasers are created equal. Early devices with less than 0.5W power often struggled to deliver meaningful results in vivo. Today’s Class IV therapy lasers deliver higher power, allowing clinicians to:

• Penetrate deeper tissues effectively
• Cover larger treatment areas in less time
• Provide consistent, reproducible clinical outcomes

For example, where lower-powered devices may require prolonged treatment at multiple small points, Class IV lasers can deliver a therapeutic dose efficiently across the target tissue in just 4–7 minutes.

Clinical Application

PBM is versatile and can be used for a wide range of conditions:

• Acute injuries – supporting faster control of pain and swelling
• Chronic conditions – offering non-pharmacological relief for persistent musculoskeletal pain
• Sports recovery – reducing delayed onset muscle soreness (DOMS) and accelerating return to play

Evidence supports its use in conditions such as:

• Neck and low back pain
• Sciatica and arthritis
• Tendinopathies and plantar fasciitis
• TMJ disorders
• Post-surgical rehabilitation

It’s no surprise that elite sports teams and clinics are increasingly adopting PBM as part of their multimodal approach.

A Clinician’s Perspective

At Hive Health Clinic in Swansea, PBM has transformed patient outcomes. One clinician shared:

“We use it with the majority of our patients now, all with good results. One patient with shoulder pain couldn’t raise his arm above shoulder height and was on the list for surgery. After the second session, he had full range of motion and postponed his operation.”

Beyond outcomes, clinicians report improvements in workflow efficiency, patient satisfaction, and even new referrals through word-of-mouth.

Bringing PBM Into Your Practice

Laser therapy is drug-free, non-invasive, and efficient—making it an ideal complement to manual therapy, exercise rehabilitation, and traditional treatment protocols.

If you’re considering integrating PBM:

• Look for evidence-based Class IV devices capable of reaching deep tissues
• Explore training and support to build clinician confidence
• Evaluate ROI with patient demand and treatment efficiency in mind

Final Word

As healthcare shifts towards holistic, non-pharmacological solutions, PBM offers clinicians a scientifically validated, patient-friendly tool to improve outcomes. Whether you’re treating acute sports injuries, chronic musculoskeletal pain, or post-operative cases, laser therapy can enhance your care pathway and set your clinic apart.
