CONCLUSION
After controlling for demographic factors and multiple severity
indicators, patients suffering nonspecific work-related LBP who
received health services mostly or only from a chiropractor had a
lower risk of recurrent disability than the risk of any other provider
type. Even without an improvement in days until recurrent disability,
our findings seem to support the use of chiropractor services,
as chiropractor services generally cost less than services from other
providers. If a lower rate of disability recurrence in work-related
LBP cases for chiropractors holds as true, it is important to identify
the mechanism of action.
