Sports Injuries

Sports InjuriesPain is believed to originate from an ionic differentiation of potassium (K+) and sodium (Na+) ions across a cellular membrane. Theralase 905 nm super-pulsed laser technology increases cellular membrane permeability and causes a reabsorption of sodium and expulsion of potassium molecules, removing the gradient and thus the pain signal at source.

Anti-Inflammation

LLLT has an anti-oedemic effect, as it causes vasodilation, but also because it activates the lymphatic drainage system to drain interstitial fluid (drains swollen areas).

Anti-Pain (Analgesic)

As a result of reduced inflammation, there is less oedema and therefore less pain. LLLT stimulates vasodilation and lymphatic drainage, which increases the reabsorption of pain-causing products. LLLT delivers 905 nm super-pulsed infrared wavelength light, which is absorbed by the bi-lipid layer comprising the cellular membrane and thus regulates the nerve cell's sodium-potassium pump. This pump maintains the potential across the membrane of a nerve cell, which leads to pain transmission signals. By regulating the pump, transmission of pain signals from the area can be eliminated.

Clinical Studies Utilizing 904nm Lasers

Currently there are over 100 Positive Double Blind Studies dating as far back as 1984. One source for hundreds of abstracts online is www.laser.nu.

Since 1984 the technology has become far more advanced and the technology (laser) that is promoted by Theralase is still unique Class 3b laser due to the wavelengths utilized and the 50 watts of power behind it.

Consequently, the most successful clinical in regards to efficacy are pulsed lasers utilizing 904 nm laser diodes. (Newest modification of this wavelength is 905 technology). Here are the most informative double blind studies.
