Despite the abundance of theories concerning the effects of chiropractic adjustments on brain function, this remains an understudies area for the profession.

Quantitative Electroencephalography (qEEG)is a technique that allows for an in-depth analysis of brain function. A normative database will be used to compare before, during and after effects of chiropractic adjustments on brain function. This will include usage of Low Resolution Electromagnetic Tomography (LORETA).

This study seeks to objectively document effects of chiropractic adjustments on brain function.

Primary Purpose: Health Services Research
Official Title: Effects of Chiropractic Adjustments on Brain Function Using Quantitative Encephalography

Further study details as provided by Life University:

Primary Outcome Measures:
  • Changes in quantitative EEG values as compared to a normative database [ Time Frame: Baseline, during adjustment, after adjustment, follow up in 7 days ] [ Designated as safety issue: No ]

    There will be a baseline measurement. There will be measurements during the adjustment. There will be measurements immediately after the adjustment. There will be measurements 7 days after the adjustment.

    Data will then be analyzed comparing values to a normative database. This database is adjusted for age. This will generate z-score values in addition to raw EEG values. Statistical analysis of P-values will then be run to test significance of changes.

Secondary Outcome Measures:
  • Behavioral assessment questionaire [ Time Frame: At baseline, one week after adjustment. ] [ Designated as safety issue: No ]
    Subject will be asked to complete the Achenbach System of Empirically Based Assessment. This assessment asks questions about subjects adaptive and maladaptive functioning. This information is comparing the subject to other people their age.

Estimated Enrollment: 30
Study Start Date: June 2013
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Sham Comparator: Placebo group
Ten people. Participants will receive what appears to be a chiropractic adjustment but which actually is not. This is the sham adjustment. Participants will also fill out Achenbach questionnaire. There will be a follow up in 7 days.
Other: Sham adjustment
Active Comparator: Chiropractic adjustment
Ten people. Group will be getting chiropractic adjustments. Participants will be filling out Achenbach questionnaire. There will be a follow up in 7 days.
Other: Chiropractic adjustment
No Intervention: Control group
Ten people. This group will simply have their EEG recorded at baseline and after 7 days. There will be an Achenbach questionnaire like the two other groups.
