Veterans Response to Dosage in Chiropractic Therapy
VERDICT (Veterans Response to Dosage in Chiropractic Therapy): A Pragmatic Randomized Trial Addressing Dose Effects for Chronic Low Back Pain
Source: ClinicalTrials.gov · Last updated 11 Aug 2026
Brief summary (registry, in English)
This study evaluates how Veterans with chronic low back pain (cLBP) respond to varying doses of chiropractic therapy and how health services utilization are impacted as a result. There are 2 phases in this study. In Phase 1, half of participants will be randomized to receive a low dose (1-5 visits) of chiropractic care for 10 weeks, while the other half will be randomized to receive a higher dose (8-12 visits) for 10 weeks. At the end of Phase 1, participants in each group will be randomized again to receive either chronic chiropractic pain management (CCPM) (1 scheduled chiropractic visit per month x 10 months) or no CCPM for 10 months.
