Free clinician calculator

Oswestry Disability Index calculator

Score the 10-section ODI in the browser. Skipped sections are removed from the denominator, the score is interpreted against the SpineOS ODI bands, and the MCID is shown so a change is not overcalled.

Current ODI -- Answer at least one section

Score each answered section

Leave a section blank if it was skipped. A blank section is not counted as zero.

How the score is calculated

ODI = section total / (5 x answered sections) x 100. A skipped section reduces the denominator. For example, nine answered sections are scored out of 45, not 50.

Patients complete ODI on their phone in EasySpine

SpineOS collects ODI at consistent timepoints, applies the skipped-section rule, labels the band, and tracks MCID-aware change for clinician review.
