Summary

This study aims to investigate the circulation and oxygenation changes of deep tissue respond on low level light/laser therapy (LLLT) in the healthy population. The investigators used a self-made near infrared spectroscopy (NIRS) instrument to noninvasively monitor hemodynamic indicators of brain and forearm muscle groups, including total hemoglobin (\[tHb\]), and blood flow (BF) and oxygen consumption (VO2).

Detailed description

Low level light/laser therapy (LLLT) employs visible or near-infrared light generated from a laser or light emitting diode (LED) system. It has beneficial effects on a wide range of disease, including improving wound healing, reducing pain, improving memory, treat cancer, and many other human applications. This study aims to investigate the circulation and oxygenation changes of deep tissue respond on low level light/laser therapy (LLLT) in the healthy population. The investigators used a self-made near infrared spectroscopy (NIRS) instrument to noninvasively monitor hemodynamic indicators of brain and forearm muscle groups, including total hemoglobin (\[tHb\]), and blood flow (BF) and oxygen consumption (VO2). Then the investigators concluded the effect of LLLT, according to compare the difference between the experimental group and control group.
