Science of Class 4 Laser Therapy

Photobiomodulation (PBM) is a light therapy that uses red and near infra-red light to induce photochemical reactions in the body on the molecular and cellular levels. Research protocols combining wavelengths, pulsing and power to achieve unparalleled therapeutic effects including modulation of inflammation, reduction in pain, accelerated tissue healing and increased circulation. 

Cellular Effects

During laser therapy, infrared laser light interacts with tissues at the cellular level increasing metabolic activity within the cell. By improving the transport of nutrients across the cell membrane, the increased production of cellular energy (ATP) is stimulated. The cascade of beneficial effects that follows includes increased cellular function and tissue repair.

Therapeutic Effects

During each painless treatment, laser energy increases circulation, drawing water, oxygen, and nutrients to the damaged area. This creates an optimal healing environment that reduces inflammation, swelling, muscle spasms, stiffness and pain. As the injured area returns to normal, function is restored and pain is relieved.
