In 1992, an Australian study compared Mechanical Low-Back Pain: A Comparison of Medical and Chiropractic Management within the Victorian WorkCare Scheme. Comparisons of costs and outcomes were made between the two samples. Results showed:
- A significantly lower number of claimants requiring compensation days when chiropractic management was chosen.
- Fewer compensation days taken by claimants who received chiropractic management.
- A greater number of patients progressed to chronic status when medical management was chosen.
- A greater average payment per claim with medical management.
