Table 3.

Changes in headache disability (HIT-6) and quality of life (SF-36v2 physical component score (PCS) and mental component score (MCS)) from baseline to 12 months post-microstimulator insertion are provided (mean ± SD (range))

Analysis	HIT-6 headache disability		SF-36v2 quality of life – PCS		SF-36v2 quality of life – MCS
	Baseline	12 months	Baseline	12 months	Baseline	12 months
All patients	64.3 ± 6.6 (41–78)	56.0 ± 11.1 (36–76)	40.4 ± 7.4 (23.9–57.6)	43.5 ± 10.1 (21.7–63.3)	32.2 ± 13.7 (6.0–59.7)	39.2 ± 15.0 (6.1–65.1)
	p < 0.0001, n = 80		p = 0.0062, n = 79		p = 0.0003, n = 79
Therapeutic responders only	64.7 ± 6.9 (41–78)	53.2 ± 11.1 (36–74)	39.9 ± 7.7 (23.9–57.6)	45.2 ± 10.4 (22.3–63.3)	32.2 ± 12.6 (14.4–57.7)	40.8 ± 14.8 (6.1–65.1)
	p < 0.0001, n = 53		p = 0.0001, n = 52		p = 0.0005, n = 52

Differences were statistically significant for all patients, as well as for therapeutic responders
