Objective:  Research is needed to determine if P300 wave analysis has significance as an outcome assessment of subluxation-based chiropractic care in the addiction treatment setting.

Methods:  Two groups of male subjects in residential addiction treatment are studied for 90 days. The chiropractic group received chiropractic adjustments using Torque Release Technique® and the Integrator® adjusting instrument three times per week. The Placebo group received a sham adjustment three times per week. Both groups were assessed with the Beck’s Depression Inventory and the Speilberger State-Trait Anxiety Questionnaire at intake and every 30 days.  P300 analysis was taken at intake and every week for both groups.

Results:  In the chiropractic group; depression scores improved by 97%, anxiety scores improved by 36.5% with 100% retention rate in the chiropractic group and 0% retention rate in the Placebo group.  P300 wave results improved in the chiropractic group.

Conclusions:  We conclude that chiropractic care utilizing the Torque Release Technique® improves retention rates, psychosocial inventory assessments and prevents relapse. More research is warranted to determine the significance in the use of the P300 wave as an outcome strategy in chiropractic intervention.  Subluxation-based chiropractic care should be considered as standard care in the management of addicted individuals.
