The study will look at a non-invasive treatment for people suffering with chronic and episodic headaches. Study subjects will be randomized to an active treatment or an in-active treatment for 2 weeks. After the 2 weeks all subjects will continue to treat with an active treatment for an additional 2 weeks.

Primary Outcome Measures:
  • severity of headache [ Time Frame: 4 weeks ]
    Comparison of the pain free rates at 15 minutes following the treatment

Secondary Outcome Measures:
  • Reduction of disability [ Time Frame: 4 weeks ]
    Comparison of scores of disability on a 5 step disability scale

  • Quality of Life [ Time Frame: 4 weeks ]
    Questionnaires answered by the subjects will be compared

  • Use of rescue medication [ Time Frame: 4 weeks ]
    Comparison of subjects who need to the use of medication for rescue of symptoms

  • Pain [ Time Frame: 4 weeks ]
    Pain free from symptoms at 30 minutes after treatment

Enrollment: 120
Study Start Date: August 2013
Study Completion Date: January 2015
Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: gammacore
gammacore active device to be used noninvasively to the vagal nerve in the neck.
Device: gammaCore
Vagal stimulation
Placebo Comparator: inactive gammacore
same as the active treatment, but without the therapy treatment provided
Device: gammaCore
Vagal stimulation

Detailed Description:
The study is a prospective double blind, randomized, sham-controlled, multi-center investigation designed for comparison of two parallel groups, GammaCore® (active treatment) and a sham, (in-active) treatment. The study period begins with a 1-week run-in period, followed by a 2 week comparative period when the subjects are randomized (1:1) to either active treatment or sham (in-active) treatment. The comparative period will be followed by an open label 2 week period, where the subjects in the sham treatment group will switch in treatment assignment and receive an active treatment and the active group will continue to receive an active treatment.
