The Oswestry Disability Index (ODI) is an index is derived from the Oswestry Low Back Pain Questionnaire used by clinicians and researchers to quantify disability for low back pain.
This validated questionnaire was first published by Jeremy Fairbank et al. in Physiotherapy in 1980. The current version was published in the journal Spine in 2000. The Oswestry Disability Index is currently considered by many as the gold standard for measuring degree of disability and estimating quality of life in a person with low back pain.
The patient questionnaire contains topics concerning intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel. Each topic category is followed by 6 statements describing different potential scenarios in the patient's life relating to the topic. The patient then checks the statement which most closely resembles their situation. Each question is scored on a scale of 0-5 with the first statement being zero and indicating the least amount of disability and the last statement is scored 5 indicating most severe disability. The index is scored from 0 to 100. Zero is equated with no disability and 100 being maximum disability.
