Laser therapy: A proven solution for pain management

Branded content sponsored by Summus Medical Laser

Laser therapy, formally known as photobiomodulation (PBM), is emerging as a transformative approach in healthcare.

The analogy of a “tsunami approaching the shore” aptly captures the growing impact this technology is having in chiropractic practice, specifically in pain management and injury recovery. As research evolves, what began as a subtle ripple in the ocean of therapeutic options is now becoming a powerful force that healthcare practitioners should adopt to optimize patient outcomes.

A promising alternative to traditional methods

The science behind photobiomodulation is both proven and fascinating. PBM is a light therapy that employs specific wavelengths of light to induce photochemical reactions in the body on the molecular and cellular levels. By delivering light energy into the body’s cells, PBM stimulates the production of adenosine triphosphate (ATP), the energy currency of cells, thereby accelerating cellular recovery and increased circulation. This natural, noninvasive therapy can be particularly effective for treating arthritis and chronic pain, offering a promising alternative to traditional methods, such as medication and or surgery.

One of the most critical aspects of effective PBM therapy lies in the precise use of wavelengths and power dosages. In the early stages, many therapeutic lasers were underpowered and lacked the ability to consistently generate a photobiological response in tissues. Consequently, early adopters of this technology often saw inconsistent results. However, as research advanced, scientists identified optimal wavelengths—typically in the red and near-infrared spectrum—and appropriate energy densities to elicit a significant biological response. This development marked a turning point in the efficacy of therapeutic lasers, making them a viable and potent treatment option.

The impact of laser therapy on pain management

Today, reputable scientific journals, including the Journal of Orthopaedic and Sports Physical Therapy (JOSPT), recommend PBM therapy for a range of conditions.¹ Achilles tendinopathy, plantar fasciitis and other soft tissue injuries are just a few examples where PBM has been shown to reduce pain and promote recovery. Clinical trials consistently report positive outcomes, underscoring the reliability and impact of PBM in rehabilitation and pain management.

Moreover, quality companies are producing state-of-the-art therapeutic lasers that meet the necessary power and wavelength standards to achieve optimal results. Healthcare providers now have access to tools that not only could but should be incorporated into their treatment protocols. The growing body of research and improved technology mean the days of underpowered lasers are over; we now have devices that can consistently produce meaningful therapeutic outcomes.

Final thoughts

In summary, PBM is no longer a niche treatment modality but a well-researched, proven therapy with significant implications for patient care. The evolution of therapeutic lasers from underpowered devices to sophisticated tools capable of delivering profound biological benefits has been nothing short of remarkable. As healthcare professionals, incorporating this therapy into patient care is not only a possibility but an imperative—one that holds the potential to revolutionize pain management, optimize recovery and enhance overall well-being.
