Further advancements in the near infrared lightemitting diode: review

Abstract

During the last decade, significant advances have been made in the application of using a near infrared LED light-emitting diode over the use of low-level laser light therapy for a wide range of healing and rehabilitation processes. Near infrared LED has been shown to represent a novel, non-invasive, and effective coadjutant therapeutic intervention for the treatment of numerous diseases. With the discovery of the use of gallium arsenate (red light), the near infrared light-emitting diode has shown to be an effective therapy in the use of wound, bone, and traumatic brain injuries. Specific applications include wound healing, dentistry, peripheral nerve injury, depression, neurological disease (including Parkinson’s Disease, depression, and dementia), aging cerebrovascular disease, and traumatic brain injury. Most recently, the application of infrared light on brain tumors (photodynamic therapy) has started to provide a positive result. More evidence-based research is required to support this growing coadjutant therapeutic intervention.
