Revised Oswestry Low Back Pain Disability Index

Headache Disability Index
Using this system, if “YES” is checked on any given line, that answer is given 4

points. Add up the total points. That number is the percent disability.
Lower Extremity Disability Index
Add up the total points from all sections and subtract this total from 80. Divide this
