BACKGROUND CONTEXT: The optimal number of visits for the care of cervicogenic headache (CGH) with spinal manipulative therapy (SMT) is unknown.  

PURPOSE: To identify the dose-response relationship between visits for SMT and chronic
CGH outcomes; to evaluate the efficacy of SMT by comparison with light massage control.  

STUDY DESIGN/SETTING: Two-site, open-label randomized controlled trial.  

PATIENT SAMPLE: Participants were 256 adults with chronic CGH

OUTCOME MEASURES: The primary outcome was days with CGH in the prior 4 weeks evaluated at the 12- and 24-week primary endpoints.  Secondary outcomes included CGH days at remaining endpoints, pain intensity, disability, perceived improvement, medication use, and patient satisfaction.  

METHODS: Participants were randomized to 4 dose levels of chiropractic SMT: 0, 6, 12, 18 sessions.  They were treated 3 times per week for 6 weeks and received a focused light- massage control at sessions when SMT was not assigned.  Linear dose effects and comparisons to the no-manipulation control group were evaluated at 6, 12, 24, 39, and 52 weeks.  This study was funded by the National Center for Complementary and Integrative Health (R01AT006330) and is registered at ClinicalTrials.gov (NCT01530321).  The authors declared no conflicts of interests.  

RESULTS: A linear dose-response was observed for all follow-ups, a reduction of approximately 1 CGH day/4 weeks per additional 6 SMT visits (p < .05); a maximal effective dose could not be determined.  CGH days/4 weeks were reduced from about 16 to 8 for the highest and most effective dose of 18 SMT visits.  Mean differences in CGH days/ 4 weeks between 18 SMT visits and control were -3.3 (p = .004) and -2.9 (p = .017) at the primary endpoints, and similar in magnitude at the remaining endpoints ( p < .05).  Differences between other SMT does and control were smaller in magnitude (p > .05).  CGH intensity showed no important improvement nor differed by dose.  Other secondary outcomes were generally supportive of the primary.  

CONCLUSION: There was a linear dose-response relationship between SMT visits and days with CGH.  For the highest and most effective dose of 18 SMT visits, CGH days were reduced by half, and about 3 more days per month than for the light-massage control.
