An important distinction is between statistical signifi-
cance and clinical relevance of findings. One study
howed a statistically significant difference in pain-
related disability on ODI; however, the difference was
very small and may not have represented a clinically
relevant change.

Currently, there is consensus regard-
ng minimal clinically important changes for pain and
unction (measured by RMDQ, not ODI) in back
pain.

For LBP, 30% on VAS/NRS for pain is consid-
ered to be clinically significant and 2–3 points (8–12%)
on the RMDQ for function is also considered as clinic-
ally significant.
