LASER POWER LOW, THE RED LIGHT SPECTRUM IN NERVE INJURY PERIPHERAL: SYSTEMATIC REVIEW

Abstract

The peripheral nerves are often compromised by injuries. Among the most common causes are: trauma, stretch, clamping, compression and crushing of the nerve tissue, which results in impairment motor, sensory and functional limitations. There are various forms of treatment, such nonsurgical therapeutic approaches, we can mention the low power laser, which has a number of indications, playing analgesic, anti-inflammatory and healing action. However, there is an apparent lack in Brazilian literature regarding the effect of the laser of the visible light range (red light) as a treatment modality for peripheral nerve injury, as well as the lack of published systematic reviews. Thus, the aim of this study was to systematically review of low power laser in the red light spectrum in peripheral nerve injury. For this study were consulted Scielo databases, Lilacs and Google Scholar, with the following keywords: Low power laser; Low level laser and peripheral nerve injury; Low level laser 660 nm in peripheral nerve injury and “Laser 670 nm” “sciatica”. Thus, 20 studies were found, but due to the inclusion and exclusion criteria, only five were selected. After analysis of the data, we concluded that the low-power laser in the red light spectrum in peripheral nerve injury in two of the five included articles
through national literature has demonstrated to the nerve regeneration process, but the parameters used are varied which complicates a comparison between studies.
