The Oswestry Disability Questionnaire, commonly called the Oswestry Disability Index or ODI, is a 10-section patient-reported outcome measure used to assess disability related to low back pain. Scores are usually expressed as a percentage from 0% to 100%, where higher scores indicate greater disability. The ODI can support baseline assessment and progress tracking, but it does not diagnose the cause of low back pain or determine readiness for activity on its own.
Low back pain can affect sitting, standing, walking, lifting, sleep, work, social activity, travel, exercise participation and confidence with movement.
The Oswestry Disability Questionnaire, more commonly known as the Oswestry Disability Index or ODI, is one of the most widely used patient-reported outcome measures for low back pain-related disability.
It is commonly used for:
acute low back pain monitoring
persistent low back pain tracking
lumbar radicular pain contexts
spinal stenosis outcome monitoring
pre- and post-spinal surgery reporting
rehabilitation progress tracking
work-related back pain reporting
long-term functional outcome monitoring
The ODI is a self-administered 10-section questionnaire. Each section is scored from 0 to 5, and the total is converted to a percentage from 0 to 100. A higher score indicates greater disability.
Outcome measure: Oswestry Disability Questionnaire
Common name: Oswestry Disability Index
Abbreviation: ODI
Body region: Low back / lumbar spine
Type: Patient-reported outcome measure
Number of sections: 10
Item score: 0–5 per section
Maximum raw score: 50 if all 10 sections are completed
Converted score: percentage from 0% to 100%
Higher score means: Greater reported low back-related disability
Lower score means: Less reported low back-related disability
Best used for: Baseline assessment, reassessment and disability tracking
Key limitation: ODI does not diagnose the cause of back pain or replace professional judgement
The Oswestry Disability Questionnaire is a low back pain-specific patient-reported outcome measure.
It asks the client to rate how their back pain affects different areas of daily life.
The ODI usually includes sections related to:
pain intensity
personal care
lifting
walking
sitting
standing
sleeping
sex life, where included and appropriate
social life
travelling
The official ODI is distributed through Mapi Research Trust, which provides information about copyright, licensing, scoring, translations and versions.
The ODI is used because low back pain impact is not always fully explained by physical tests alone.
A client may show improving range of motion or strength but still report:
difficulty sitting for work
pain during lifting
reduced walking tolerance
sleep disruption
fear of activity
reduced social participation
reduced confidence with daily tasks
ongoing disability despite symptom improvement
The ODI can help professionals:
establish a baseline
quantify self-reported disability
identify which life areas are most affected
monitor change over time
support client education
guide goal-setting conversations
combine subjective and physical findings
improve progress reporting in Measurz
The ODI should support assessment reasoning and monitoring. It should not be used as a stand-alone diagnostic, treatment or clearance tool.
The ODI measures perceived disability related to low back pain.
This section captures how intense the client’s pain feels.
It may provide context around:
symptom severity
irritability
perceived pain burden
change over time
This section captures whether back pain affects self-care tasks.
It may include:
washing
dressing
daily care activities
independence
This section captures difficulty lifting because of back pain.
It may provide insight into:
load tolerance
fear of lifting
work limitations
gym or training confidence
This section captures walking limitation.
It may provide context around:
walking tolerance
symptom provocation
mobility restriction
confidence with longer distances
This section captures sitting tolerance.
It may be especially relevant for:
office workers
drivers
students
people with sitting-provoked symptoms
This section captures standing tolerance.
It may be relevant for:
retail workers
trades
teachers
daily activity demands
social participation
This section captures sleep disruption related to back pain.
Sleep responses may be influenced by pain, stress, positioning, general health and other factors.
Some ODI versions include a sex life section.
Use this respectfully and appropriately.
If the client chooses not to answer, record the missing item and follow scoring guidance for the version being used.
This section captures participation in social activities.
It may reflect:
activity avoidance
pain behaviour
confidence
fatigue
participation restriction
This section captures tolerance to travel, sitting and movement during transport.
It may be relevant for:
commuters
drivers
athletes
clients travelling for work or sport
The ODI may be useful for:
exercise professionals
rehabilitation practitioners
strength and conditioning coaches
allied health support teams
movement assessment professionals
workplace health professionals
students learning outcome measures
professionals using Measurz or MAT for structured progress tracking
It may be relevant for clients with:
acute low back pain
persistent low back pain
recurrent back pain
lumbar radicular symptoms
lumbar spinal stenosis
post-operative lumbar spine recovery
work-related back pain
reduced confidence with lifting, walking, sitting or standing
The ODI is widely used across spinal conditions treated either operatively or conservatively. A 2023 lumbar surgery study described it as the most commonly used PROM to assess functional limitations in spinal conditions.
Use the ODI when you want to understand how low back pain affects daily activities and perceived disability.
It may be useful at:
initial assessment
onboarding
reassessment
flare-up review
return-to-work monitoring
return-to-lifting planning
post-operative milestones
progress review
discharge or long-term follow-up
The ODI is most useful when repeated over time using the same version and scoring method.
Use caution when:
the client cannot complete the questionnaire independently
literacy, language or cognitive factors affect responses
the wrong language version is used
multiple body regions are driving limitation
many items are missing
the client is uncomfortable answering a section
the score is being used as a diagnosis
the score is being used as a pass/fail activity decision
results are interpreted without physical assessment context
The ODI should not be used to:
diagnose the cause of low back pain
confirm disc injury
confirm nerve involvement
determine tissue healing
identify the exact pain source
clear someone for work, training or sport
replace professional judgement
replace medical assessment where needed
Oswestry Disability Questionnaire / ODI form
Official scoring guidance or validated scoring calculator
Measurz recording workflow
Client-reported symptom notes
Baseline and retest dates
Optional related physical tests, such as:
lumbar range of motion
hip range of motion
strength testing
lifting assessment
walking tolerance
sit-to-stand testing
pain with repeated movement
balance or gait assessment
work or training exposure notes
Explain the purpose of the questionnaire before the client completes it.
Example wording:
“This questionnaire helps us understand how your back pain is affecting daily activities such as sitting, standing, walking, lifting and sleep. It does not diagnose the cause of the pain, but it helps us monitor how your function changes over time.”
The ODI can be completed:
on paper
digitally
independently
verbally if assistance is needed
before a session
during reassessment
as part of a Measurz workflow
Ask the client to:
answer based on their current low back problem
choose one statement per section
choose the statement that best describes their current situation
answer every section where possible
ask for clarification if they do not understand the wording
complete the same version at each retest
Record whether the ODI was completed:
independently
digitally
on paper
verbally
with assistance
This supports repeatability and helps interpret changes over time.
If assistance is needed:
explain the instructions without leading the answer
avoid telling the client which option to choose
record that assistance was provided
use the same assistance approach at retest where possible
Do not guess missing responses.
Official scoring guidance describes each section as scored from 0 to 5 and the final score as a percentage of the maximum possible score. If one section is missed, the maximum possible score changes from 50 to 45, and the percentage should be calculated using the answered-item maximum.
Example:
10 sections answered: total score / 50 × 100
9 sections answered: total score / 45 × 100
Record any missing section clearly.
Each section is scored from 0 to 5.
A higher section score indicates greater limitation in that domain.
Total score is converted to a percentage:
ODI percentage = total score / maximum possible score × 100
If all 10 sections are completed:
maximum raw score = 50
converted score range = 0% to 100%
Retest at meaningful points, such as:
baseline
after a rehabilitation block
after a flare-up
before return to lifting
before return to work
after a change in training load
post-operative milestones
discharge or progress review
For consistency, record:
date
recent flare-ups
current pain behaviour
current work demands
current training exposure
sitting, standing and walking exposure
medication changes if relevant and appropriate
any major changes in life or activity demands
The ODI is a self-report questionnaire, so it does not create physical testing risk.
However, worsening responses may support further assessment where the client reports:
severe deterioration
worsening walking tolerance
major sleep disruption
major functional decline
new neurological symptoms
red flag symptoms
major quality-of-life impact
The ODI produces a disability percentage from 0% to 100%.
Higher scores indicate greater reported disability.
Lower scores indicate less reported disability.
0%: no reported disability
100%: maximum reported disability
Commonly used ODI categories are:
0–20%: minimal disability
21–40%: moderate disability
41–60%: severe disability
61–80%: crippled / very high disability
81–100%: bed-bound or symptom exaggeration category in traditional wording
Use these categories cautiously. Some traditional labels are outdated and may not align with current person-centred language. In Measurz education and reporting, it is safer to describe the score as minimal, moderate, severe or very high reported disability rather than using stigmatising wording.
A higher ODI score may suggest:
greater low back-related disability
more daily activity limitation
lower confidence with movement
greater difficulty with sitting, standing, walking or lifting
greater impact on sleep, social life or travel
A lower ODI score may suggest:
fewer reported limitations
better daily function
better tolerance of walking, sitting, standing or lifting
less impact on social or daily activity
An ODI score does not prove:
the diagnosis
the pain source
structural damage
disc injury
nerve compression
readiness to return to work or sport
whether imaging is required
whether one intervention caused the change
Example wording:
“Your ODI score suggests your back pain is currently having a moderate impact on daily activities. This does not tell us exactly what structure is causing the pain, but it helps us track whether your daily function is improving over time.”
For general fitness clients, ODI may help show how low back pain affects:
sitting
standing
walking
lifting
sleep
gym participation
daily activity
Interpretation cautions:
recent exercise may influence answers
fear of lifting may affect responses
symptoms from the hip or leg may also influence disability
For athletes, ODI can help track general low back-related disability, but it may not capture sport-specific performance demands.
Interpretation should also include:
sport-specific movement testing
lifting exposure
running or jumping exposure
workload changes
confidence with training
pain response to sport tasks
A low ODI score should not be treated as clearance on its own.
For older adults, ODI can help monitor how low back pain affects:
walking
standing
personal care
sleep
travel
social participation
Interpretation cautions:
other health conditions may influence scores
balance, strength and endurance may affect function
walking limitation may not be caused only by back pain
The standard ODI is mainly used in adults.
For youth clients, consider:
reading level
comprehension
parent or guardian assistance
sport and school demands
whether another measure may be more suitable
If assistance is provided, record it clearly.
For persistent symptoms, ODI can help monitor disability patterns over time.
Scores may be influenced by:
pain intensity
fear of movement
confidence
sleep
work demands
mood and stress
activity avoidance
flare-up history
Interpret alongside education, graded activity, physical function and goals.
For workplace contexts, ODI may help track how low back pain affects:
lifting
sitting
standing
travel
work-related tolerance
confidence returning to duties
Interpretation should also consider:
job demands
modified duties
psychosocial factors
workplace support
legal or compensation context where relevant
ODI is commonly used before and after lumbar spine surgery.
Interpretation should consider:
surgery type
healing stage
medical restrictions
neurological symptoms
medication use
walking tolerance
surgeon or medical guidance
A 2021 decompression study reported that ODI is commonly used in lumbar spinal stenosis outcome assessment and examined validity and responsiveness after open decompression.
Meaningful change helps interpret whether an ODI change is likely to matter.
Key terms:
MCID / MIC: the smallest change that may be meaningful to clients or professionals, depending on the method used
MDC: the amount of change likely needed to exceed measurement error
SEM: the estimated measurement error around a score
Responsiveness: the ability of the measure to detect change over time
ODI meaningful change values vary across populations, settings and methods.
A study on responsiveness and minimum important change noted that proposed ODI minimum important change values include a reduction of 10 points or a 30% decrease from baseline, but these should be interpreted in relation to the population and context.
A 2024 registry-based study assessed responsiveness and minimal important change for the ODI using Norwegian neck and back registry data, showing that meaningful change interpretation remains an active research area and should be population-specific.
When interpreting ODI change:
compare the percentage score with baseline
consider whether the change exceeds available MCID/MIC or MDC values for the population
check whether the change aligns with client goals
check whether activity exposure has increased
consider pain, walking tolerance, sitting tolerance, strength and movement findings
avoid over-interpreting small changes
Reported meaningful change values may vary by:
acute versus persistent low back pain
surgical versus non-surgical care
spinal stenosis versus general low back pain
baseline disability
follow-up timeframe
anchor method
language version
scoring version
When no matching MCID, MDC or SEM value exists, interpretation should rely more heavily on:
baseline comparison
repeated measurement
client-reported change
physical assessment findings
activity exposure
professional judgement
Published ODI normative and reference values are more limited than clinical cut-off categories.
A 2012 study aimed to establish normative ODI scores and a cut-off value for disability in people with low back pain. The study noted that ODI was commonly used for low back pain, but normative score work was limited before that point.
More recent work continues to address the need for population-based normative values. A 2026 Japanese validation study noted that population-based ODI normative values are scarce.
Practical comparison guidance:
Use the client’s own baseline as the primary comparison.
Compare ODI percentage change over time.
Interpret broad categories as context, not strict labels.
Consider age, work demands, activity exposure and symptom duration.
Combine ODI with pain, function and physical assessment findings.
Avoid using ODI alone as a return-to-work, return-to-training or referral decision.
Reference values should be interpreted cautiously because ODI scores may differ by:
age
sex
country
language version
work demands
symptom duration
spinal condition
surgical status
psychosocial context
activity exposure
The ODI has extensive evidence and is one of the most widely used low back pain disability measures.
A 2015 review of culturally adapted ODI versions examined adaptation processes, construct validity, test-retest reliability and internal consistency, showing broad international use and the importance of validated language versions.
A 2023 lumbar spinal surgery study reported that ODI remains a common PROM for spinal conditions and found it had high reliability and validity among people undergoing lumbar spinal surgery.
A 2021 study in lumbar canal stenosis examined construct validity and responsiveness of ODI, Roland-Morris Disability Questionnaire, SF-12 physical and mental component scores after open decompression.
Reliability and validity are stronger when:
the correct ODI version is used
the correct language version is used
all relevant sections are completed
missing items are handled consistently
the same scoring method is repeated
retesting occurs at meaningful time points
results are interpreted alongside physical and functional assessment
Interpret cautiously when:
multiple sections are missing
the client is uncomfortable answering some items
symptoms are not primarily low back-related
multiple body regions affect function
the score is used as a stand-alone diagnostic or clearance decision
the language version has not been validated for the client population
Common errors include:
treating ODI as a diagnosis
using ODI as return-to-work or return-to-sport clearance
not converting raw score to percentage correctly
forgetting to adjust the denominator for missing items
ignoring missing sections
using inconsistent ODI versions
not recording completion method
over-interpreting small changes
using traditional severity labels without context
interpreting the score without physical assessment findings
Limitations include:
self-report can be influenced by mood, expectations and recent activity
some sections may be sensitive or not relevant for all clients
scores do not identify the exact physical cause of symptoms
meaningful change values vary across populations
normative values are limited
ODI may not capture sport-specific performance well
it should be paired with physical assessment and client goals
The ODI may help professionals:
document baseline low back-related disability
identify which daily activities are most affected
monitor change over time
track response during rehabilitation or training modification
support return-to-work discussions
guide goal-setting conversations
improve client education
strengthen Measurz reports
For fitness clients, ODI can show whether back pain is affecting lifting, walking, sitting or gym participation.
For workplace clients, ODI can help track disability related to sitting, standing, lifting, travel and daily function.
For persistent low back pain, ODI can help monitor whether disability is improving even if pain fluctuates.
For Measurz users, ODI is most useful when combined with objective and practical measures such as:
lumbar range of motion
hip range of motion
trunk endurance
lifting tolerance
walking tolerance
sit-to-stand performance
pain score
confidence measures
work or training exposure

reporting quality
It measures self-reported disability related to low back pain across daily activities such as sitting, standing, walking, lifting, sleep, social life and travel.
Yes. It is commonly called the Oswestry Disability Index, or ODI.
Each of the 10 sections is scored from 0 to 5. The total is divided by the maximum possible score and multiplied by 100 to produce a disability percentage.
Yes. A higher ODI percentage indicates greater reported low back-related disability.
No. ODI measures disability related to low back pain. It does not diagnose the cause or identify the tissue source of symptoms.
Commonly cited guidance suggests a 10-point reduction or about 30% improvement from baseline may be meaningful, but meaningful change varies by population and context.
It can track general low back-related disability, but it may not capture sport-specific performance demands. It should be paired with sport-specific testing and workload information.
It can be repeated at baseline, reassessment, after a rehabilitation phase, after a flare-up, during return-to-work planning and at progress review.
The Oswestry Disability Questionnaire is also known as the Oswestry Disability Index or ODI.
It is a 10-section low back pain disability questionnaire.
Each section is scored from 0 to 5.
Scores are converted to a percentage from 0% to 100%.
Higher scores indicate greater reported disability.
ODI does not diagnose the cause of back pain or clear a client for activity.
Meaningful change values vary, but a 10-point reduction or 30% improvement is commonly cited in the literature.
Measurz should record version, raw score, denominator, percentage score, missing sections, completion method, baseline comparison, related findings and retest plan.
