The Utah Study - fewer costs and days lost
This 1988 Utah workers' compensation board study found a tenfold savings for mean
compensation costs in back-related injuries treated by chiropractors as compared with medical doctors ($68.38 vs. $668.39). To ensure accurate and true results, only those back-related injuries
with the same diagnostic codes were compared between the two treatment groups. Also, the medical treatments assessed were limited to nonsurgical medical treatments only.

The Florida Study - shorter disability, lower costs, and lower hospitalization rates
This large study - conducted by the State of Florida - examined 10,652 patients who
sustained back-related injuries on the job. Their findings revealed individuals who received chiropractic care compared with standard medical care experienced had a (i) 51.3 percent shorter
temporary total disability duration (ii) lower treatment cost by 58.8 percent (iii) 20.3 percent hospitalization rate in the chiropractic care group vs. 52.2 percent rate in the medical care group.

The California Study - chiropractic patients get back to work sooner
In this study, Richard Wolf, MD followed 500 individuals sent for chiropractic treatments
and 500 individuals sent to medical doctors for treatment. Those who received chiropractic treatments returned to work in an average of 15.6 days vs. 32 days in those who received treatments from
medical doctors.

The Oregon Study - chiropractic gets individuals back to work, and fast!
This Oregon study found that individuals with workers' compensation claims returned to work
significantly faster under chiropractic care compared with medical care. In fact, under chiropractic care 82% were able to return to work after one week compared with only 41% in those who received
medical care.

The Australian Study
In this Australian study, 1,996 workers' compensation cases were evaluated in patients who
experienced work-related mechanical low back pain. It was found that those individuals who received chiropractic care for their back pain returned to work 4 times faster (6.26 days vs. 25.56 days)
and had treatment that cost 4 times less ($392 vs. $1,569) than those who received treatments from medical doctors. Also, in those patients who received chiropractic care there was a significantly
lower incidence of progression to a chronic low back pain status.
