Basic science evidence suggests that chiropractic adjustments modulate immune mediators in healthy individuals in the short term and cortisol levels in symptomatic and asymptomatic individuals. However, clinically relevant research has not yet been done. The purpose of this study is to determine whether there is an association between regular chiropractic care and immune status. Two groups, one that has received regular chiropractic care over the past 12 months and one that has not, will complete self-reporting questionnaires and blood analyses relevant to assessing their immune status. The results of this observational case-control study will help inform the design of future experimental trials.
