FIG. 3.

Second LED device (console model with three LED cluster heads) used by P2 during home treatments. These were used in three different areas at the same time. Here, two LED cluster heads are held in place, on left and right high-frontal areas on the scalp, with a loose-fitting elastic cap. The third LED cluster head has been placed on the sole of the foot (acupuncture point, Kidney 1); it is held in place with a soft, flexible, elastic band, secured with a Velcro strap. The usual treatment time is 10 min per area (13.3 J/cm²). See text for further description of this second LED device.
