Veterans Response to Dosage in Chiropractic Therapy (VERDICT)

  • Study HIC#:2000025406
  • Last Updated:12/01/2021

Veterans with chronic low back pain (cLBP) often receive non-pharmacological treatment such as chiropractic care, but the ideal number of visits for such treatment is not known.  This study will measure differences in patient outcomes for cLBP between participants that receive a lower or higher number of chiropractic visits within a 10-week period. Some participants may receive additional visits for the next 10 months. The study is being conducted at the VA Connecticut Healthcare System in West Haven, CT.

Trial Purpose and Description

This is a pragmatic randomized trial of Veterans with chronic low back pain comparing 1-5 visits of multimodal chiropractic care vs. 8-12 visits over a 10-week period.

The primary outcome is the Roland Morris Disability Questionnaire at week 10 and week 52.
