FIGURE 1. Transmitted power at the target as a function of depth in tissue for a 780-nm CW diode laser (250 mW), measured in vivo through human skin and muscle for four treated-zone diameters (Ø 40, 20, 10, and 2 mm), illustrating the near-exponential attenuation of laser energy with penetration depth (unpublished data).

780-nm photobiomodulation advances peripheral nerve repair toward a device-ready clinical platform

No drug is approved to speed nerve regeneration for peripheral nerve injury, but four decades of research have established 780-nm continuous-wave photobiomodulation (PBM) as a...
