One study conducted on five comatose patients showed a marked increase in wakefulness and awareness after cold laser intervention. Improves Awareness in Severe TBI Patients There have been several studies conducted on human patients with TBI that suggest cold laser therapy may be beneficial.īelow, we’ll discuss 2 studies that support laser therapy and their findings. The highest wavelength at 980 nm produced the least improvements. In a study conducted on mice that compared four different wavelengths, 660 nm and 810 were found to be the most effective. For deeper issues, wavelengths between 780 and 950 nm are used.Īs far as brain injury treatments go, research has found that higher intensity waves had less positive effects than lower intensity waves. For superficial muscles, wavelengths are typically set between 600-700 nanometers. The absorbed infrared light triggers an increase in cellular respiration and other physiological responses that promote healing.ĭepending on what issue you want to treat, the wavelengths will be set to different levels. ![]() The device emits infrared and near-infrared light, which penetrates the skin and gets absorbed by the tissue beneath. Cold laser therapy works by pressing the laser device directly over the targeted area.
