GLED exposure improved all quality of life parameters reported using the modified University of Arizona pain clinic follow up questionnaire. WLED exposure had minimal improvement of several parameters in episodic (a), chronic (b), and all migraine patients (c). The following criteria were evaluated: Perceived percent improvement of migraine pain intensity, migraine headache frequency, pain duration, ability to fall asleep, ability to stay asleep, work, exercise and doing chores, after completion of WLED therapy compared with baseline (n[WLED]epi = 6–8, n[WLED]chro = 19–21). On the contrary, GLED exposure demonstrated significantly greater improvements in all measured parameters in episodic, chronic and combined migraine groups. (n[GLED]epi = 6–7, n[GLED]chro = 15–22). Data presented as average ± SEM, standard error of the mean (Mann-Whitney test, *p<0.05, **p<0.01, ***p<0.001).
