Includes two sequential placement sets with nominal power output per cluster head, 626 mW: First placement set, midline only, 6 cluster heads turned on (14 min, 5 sec); Second placement set, Left and Right sides of head simultaneously, total 12 LED cluster heads turned on (14 min, 5 s). When PhotoMedex helmet, and two LED cluster heads over the ears, and two intranasals were used, Joules per treatment = 19.1 kJ, Total Joules after 15 Treatments = 286.6 kJ.
Used with participants where the head circumference was >24 inches.
Two sequential Placement Sets: Total Time, Set A plus Set B, was 23 min 18 sec. Note, the power output and power density varied slightly, for the different number of cluster heads turned on at the same time, 5 (Set A), or 10 (Set B). When Thor helmet, and two intranasals were used, Joules per Treatment = 12.2 kJ, Total Joules after 15 Treatments = 183.2 kJ.
