Oswestry Disability Index (ODI)

The Oswestry Disability Index asks how low back pain affects ten parts of daily life, from pain intensity to travelling. Each section scores 0 to 5, and the total becomes a percent from 0 to 100: the higher, the more disability. See how to work out the percent, read the bands, judge a change after treatment or surgery, and record the result with the free template. The official form comes from its source.

What the score means. 0 to 100, percent disability.

0 to 20: Minimal disability

Most daily activities are manageable, though some people still find long sitting hard. Advice is usually enough: how to lift and sit, staying active, and general fitness.

21 to 40: Moderate disability

Sitting, lifting, and standing hurt more, and travel, social life, and work may suffer; personal care, sleep, and sex life mostly hold up. Usually managed without surgery, with active care and a graded return to activity.

41 to 60: Severe disability

Pain is still the main problem, and now personal care, sleep, social life, and travel are limited too. Look closely: review the diagnosis, check the nerves, and image or refer where the findings support it.

61 to 80: Disabling back pain

Back pain reaches into every part of life at home and at work. Act on it: a specialist review, a clear treatment plan, and support with daily tasks and work.

81 to 100: Bed-bound or symptoms overstated

The developers described people here as either confined to bed or overstating their symptoms. Watch how the person moves during the visit to tell which, and check for red flags and distress before deciding.
  • Each of the 10 sections scores 0 to 5, from its first statement to its last. Add the section scores, divide by the most possible, and multiply by 100. With all 10 answered the most possible is 50, so the percent is the raw total doubled: 19 is 38%.
  • For each blank section, take 5 off the most possible. With one blank, divide by 45: a raw total of 20 is 20 ÷ 45 × 100 = 44.4, recorded as 44%. Round to the nearest whole percent.
  • Sex life is the section most often left blank, and scaling to the sections answered handles it. If two statements in one section are marked, score the higher.
  • The developers set no fixed limit on blank sections, but every blank leaves the percent resting on fewer answers. Record how many sections the score is based on.
  • The bands are the descriptive bands Fairbank and Pynsent published in 2000, and the ODI’s official page shows them. Their own labels for the top two bands were blunter than the wording here; the meaning is the same.
  • An international consensus on back pain measures put the minimal important change for one patient at 10 points, or a 30% fall from the baseline score. After lumbar surgery, studies found about 13 points, and device trials for spinal fusion have used 15 points as the mark of success.
  • The error around a single score is about 10 to 13 points in most studies, so a change smaller than that may be noise.
  • Version 2.1a is the one most studies and clinics use. Mapi Research Trust now distributes version 2.1b, updated in 2019, and both score the same way. Version 1.0, from 1980, built its pain section around painkillers, so record the version and compare scores from the same one.
  • The modified Oswestry, common in physical therapy, replaces the sex life section with one on work and homemaking. Its scores are close to the ODI’s but not interchangeable, and its original study put the meaningful change at about 6 points.

How to give it, score it, and read it.

Before the visit

The patient fills in the official form on their own, choosing in each section the one statement that fits them now. It takes about 5 minutes.

  • Use the official form or an approved translation, unchanged
  • Hand it out before the consultation, so the exam doesn’t shape the answers
  • Let the patient know the sex life section can stay blank if it doesn’t apply
  • Check for blank sections and double marks before the patient leaves

Avoid: Retyping the form or rewording the sections as you read them. Changes alter how people answer, and the terms don’t allow them.

Working out the percent

Score each section 0 to 5, add them, divide by the most possible for the sections answered, and multiply by 100.

  • All 10 answered: double the raw total
  • One blank: divide by 45; two blanks: divide by 40
  • Two statements marked in one section: score the higher
  • Round to the nearest whole percent, and write the raw total beside it

Avoid: Dividing by 50 when a section is blank. It lowers the score every time, and it’s the most common scoring error.

What the band means

Higher means more disability. The band describes daily life; the history, exam, and imaging decide the plan.

  • See which sections carry the points: often walking and standing in stenosis, sitting in disc problems
  • Ask about red flags and examine the nerves whatever the score
  • Above 40%, review the diagnosis and look for a cause that needs more than active care
  • Above 80%, watch how the person moves during the visit before reading the score

Avoid: Using the band as a rule for surgery or time off work. It describes; it doesn’t decide.

Change after treatment or surgery

Take a baseline before treatment starts, then repeat at set points with the same version each time.

  • Count a fall of 10 points, or 30% of the baseline, as meaningful
  • After spine surgery, 3 and 12 months are the usual points, with an earlier check at about 6 weeks in many clinics
  • Read a change under 10 points with care: it may be measurement error
  • Review the plan when the score hasn’t moved by the next re-evaluation

Versions and the modified form

Several forms carry the Oswestry name. Record which one the patient filled in.

  • Version 2.1a: the one most studies use
  • Version 2.1b: distributed by Mapi Research Trust since 2019, scored the same way
  • Version 1.0: the 1980 original, with a pain section about painkillers
  • Modified Oswestry: work and homemaking in place of sex life, common in physical therapy

Avoid: Comparing a modified Oswestry score with an ODI score as if they were the same measure.

ODI result: lumbar radiculopathy after 12 weeks of physical therapy

Outpatient physical therapy, re-evaluation at 12 weeks, form completed on a clinic tablet

Presentation

46-year-old dental hygienist with left leg pain for 4 months, which began after lifting a box at home. MRI in July: left paracentral L4–L5 disc protrusion touching the L5 nerve root. At the start, leg pain was 7/10 down the outer shin to the top of the foot, worse than the back pain, and she could sit for only 15 minutes. Care to date: physical therapy twice a week for 6 weeks, then weekly, with a home program; naproxen for the first 3 weeks.

Calculation

ODI version 2.1a in English. 9 of 10 sections answered; sex life left blank, as at the start. Section scores: pain intensity 1, personal care 0, lifting 2, walking 1, sitting 2, standing 1, sleeping 1, social life 1, travelling 1. Raw total 10 out of a possible 45: 10 ÷ 45 × 100 = 22%, moderate disability, 2 points above the minimal band.

Progress

First ODI on August 14: 20 out of 45, 44%, severe disability. Now 22%: down 22 points, half the starting score, well past both the 10-point and the 30% marks. The biggest gains were in sitting, from 4 to 2, and personal care, from 2 to 0.

Red flags and exam

No bladder or bowel change, saddle numbness, fever, or weight loss. Left big toe extension 5/5, up from 4/5; ankle reflexes equal; light touch normal. Straight leg raise negative on both sides; at the start it was positive at 40° on the left. Sat through the 40-minute visit without needing to stand.

Decision

Goals met: ODI under 25 and a full clinic day without leg pain above 2/10. Discharged to her home program: a daily walk, hip hinge and trunk exercises 3 times a week, and a break from sitting every 45 minutes at work. Back on full duties with her usual patient load. Return for leg pain above 4/10 or any new weakness or numbness; repeat the ODI then.

Common mistakes, and how to avoid them.

Dividing by 50 with a section blank

A raw total of 20 with sex life blank is 44%, not 40%. In one hospital audit, every form with a blank section had been scored wrong; training and a scoring chart cut those errors to 1 in 7.

Writing the raw total as the percent

A raw total of 19 is 38%, not 19%. Record both, labelled, so the trend reads right.

Mixing versions

Version 1.0 and the modified Oswestry give scores that don’t line up exactly with version 2.1a. Record the version, and compare like with like.

Treating the band as a surgical threshold

The bands describe disability; they don’t decide treatment. A score of 38% can sit beside a clear case for surgery, and 55% beside a plan for active rehab.

Taking a very high score at face value

Above 80%, the person is either confined to bed or the score overstates the problem. Watch how they move during the visit, and look for distress and fear of movement, which need care of their own.

Frequently asked questions.

How do you score the Oswestry Disability Index?

Each of the 10 sections scores 0 to 5, from its first statement to its last. Add the section scores, divide by the most possible, which is 50 when every section is answered, and multiply by 100. With all 10 answered that’s the raw total doubled, so 19 becomes 38%. For each blank section, take 5 off the most possible: 20 over 9 sections is 20 ÷ 45 × 100 = 44%.

What does an ODI score mean?

Higher means more disability. The published bands from Fairbank and Pynsent are 0 to 20% minimal disability, 21 to 40% moderate, 41 to 60% severe, 61 to 80% back pain that limits every part of life, and 81 to 100% confined to bed or overstating symptoms. They describe daily life; the treatment decision also rests on the history, the exam, and any imaging.

What change in ODI score is clinically meaningful?

An international consensus put the minimal important change at 10 points, or a 30% fall from the baseline score. Studies after lumbar surgery found about 13 points, and device trials for spinal fusion have used 15 points as success. For the modified Oswestry used in many physical therapy clinics, the original study found about 6 points.

What if a patient skips a section?

Score the sections answered, and take 5 off the most possible for each blank one. Sex life is the section most often left blank, and scaling handles it. If two statements in one section are marked, score the higher. Ask about any blank before the patient leaves, and record how many sections the score rests on.

Which version of the ODI should I use?

Version 2.1a is the one most studies and clinics use, and Mapi Research Trust now distributes version 2.1b, updated in 2019; both score the same way. Version 1.0 from 1980 framed the pain section around painkillers, and the modified Oswestry swaps the sex life section for one on work and homemaking. Pick one, use it every time, and record it.

What is the difference between the ODI and the Roland-Morris questionnaire?

Both measure disability from low back pain. The Roland-Morris has 24 yes-or-no statements about today, scored 0 to 24, and suits milder problems, as often seen in primary care. The ODI has 10 sections of six statements each, scored as a percent, and separates people better when disability is moderate to severe, as in spine clinics. The Neck Disability Index was built on the ODI’s design, for neck pain.

Who can give the ODI?

The patient fills it in, so any member of the team can hand it out: physical therapists, chiropractors, physicians, nurses, or clinic staff. It takes about 5 minutes to complete and a minute to score, and needs no training. It was developed for adults. A clinician goes over the result with the patient.

Is the Oswestry Disability Index free?

For students, clinicians using it in patient care, and unfunded academic research, yes: download the form and its translations from ePROVIDE after a free sign-up. Funded research, healthcare organizations, and commercial users, including software companies, apply to Mapi Research Trust, and fees may apply.
