Different tissues absorb and respond to light in different ways. For this reason, photobiomodulation does not rely on a single wavelength or treatment approach.
Different wavelengths penetrate to different depths and may be selected depending on the tissues involved, your clinical presentation and your treatment goals.
Red Light (638–650 nm)
Generally selected for more superficial tissues, including the skin, scar tissue, wounds, trigger points and acupuncture points. The 650 nm wavelength is also used by the LightNeedle®, which delivers light to acupuncture points and meridian pathways without needles.
Near-Infrared Light (785–810 nm)
Near-infrared light penetrates more deeply than red light and is commonly selected to support muscles, fascia, tendons, ligaments and joints. These wavelengths are widely used in photobiomodulation research and clinical practice, particularly for soft tissue injuries, sports recovery, brain function, concussion and nervous system support where clinically appropriate.
Superpulsed Infrared (904 nm)
Designed for deeper musculoskeletal applications, superpulsed infrared may be selected to support deeper muscles, joints, bones and spinal regions where clinically appropriate. It may also be considered for conditions involving deeper tissues, such as plantar fasciitis, where treatment aims to reach structures beneath the more superficial layers.
Different parts of the body respond best to different wavelengths of light. Rather than using the same setting for every person or every condition, different wavelengths may be selected to match the tissues being treated and your individual presentation.
For example, a condition such as plantar fasciitis may involve different tissue layers. Rather than relying on a single wavelength, treatment may use different wavelengths to support superficial tissues, tendons and deeper structures where clinically appropriate.
The choice of wavelength is only one aspect of treatment planning. Dosage, treatment duration, delivery method and your individual presentation also influence how PBM is delivered.
