The Shoulder Pain and Disability Index, or SPADI, is a 13-item patient-reported outcome measure used to assess shoulder pain and shoulder-related disability. It includes a 5-item Pain subscale and an 8-item Disability subscale, with scores usually reported from 0 to 100. Higher scores indicate greater shoulder pain and disability. SPADI can support baseline assessment and progress tracking, but it does not diagnose the cause of shoulder pain or clear someone for activity on its own.
Shoulder pain can affect lifting, reaching, dressing, sleeping, carrying, work, gym training, sport and confidence with overhead movement.
The Shoulder Pain and Disability Index, commonly called SPADI, is a patient-reported outcome measure designed to assess current shoulder pain and disability.
It is commonly used for:
shoulder pain monitoring
subacromial pain syndrome
rotator cuff-related shoulder pain
frozen shoulder / adhesive capsulitis
shoulder osteoarthritis
post-operative shoulder recovery
rehabilitation progress tracking
return-to-training monitoring
research and outcome reporting
The SPADI contains 13 items across two domains: a 5-item Pain subscale and an 8-item Disability subscale. Scores are usually transformed to a 0–100 scale, where higher scores indicate greater pain and disability.
Outcome measure: Shoulder Pain and Disability Index
Abbreviation: SPADI
Body region: Shoulder
Type: Patient-reported outcome measure
Number of items: 13
Subscales: Pain and Disability
Pain items: 5
Disability items: 8
Score range: 0–100
Higher score means: Greater shoulder pain and disability
Lower score means: Less shoulder pain and disability
Best used for: Baseline assessment, reassessment and shoulder outcome tracking
Key limitation: SPADI does not diagnose the cause of shoulder pain or replace professional judgement
The SPADI is a shoulder-specific patient-reported outcome measure.
It asks the client to rate shoulder pain and difficulty with functional activities.
The SPADI has two subscales:
Pain: 5 items
Disability: 8 items
The original version used visual analogue scales, while many clinical settings now use a numeric rating scale format. The Shirley Ryan AbilityLab notes that two SPADI scoring versions exist: visual analogue scale and numeric rating scale.
The SPADI aims to measure current shoulder pain and disability rather than diagnose the underlying shoulder condition.
The SPADI is used because physical tests alone do not always show how shoulder symptoms affect the client’s daily life.
A client may show improved range of motion or strength but still report:
pain reaching overhead
pain reaching behind the back
difficulty washing hair
difficulty dressing
pain carrying objects
difficulty sleeping on the affected side
reduced gym or sport confidence
reduced work or household tolerance
The SPADI can help professionals:
establish a baseline
quantify self-reported shoulder pain and disability
monitor change over time
identify whether pain or disability is the main limitation
support client education
guide goal-setting conversations
compare subjective progress with physical testing
improve progress reporting in Measurz
The SPADI should support assessment reasoning and monitoring. It should not be used as a stand-alone diagnostic, treatment or clearance tool.
The Pain subscale captures shoulder pain severity during several situations.
It may provide context around:
worst pain
pain lying on the affected side
pain reaching for something on a high shelf
pain touching the back of the neck
pain pushing with the affected arm
The Disability subscale captures difficulty with shoulder-related functional activities.
It may provide context around:
washing hair
washing the back
putting on clothing
buttoning clothing
placing objects on a high shelf
carrying heavy objects
removing something from a back pocket
daily upper-limb function
The total SPADI score summarises pain and disability on a 0–100 scale.
A higher total score suggests greater shoulder-related impairment or disability.
The SPADI may be useful for:
exercise professionals
rehabilitation practitioners
strength and conditioning coaches
workplace health professionals
allied health support teams
movement assessment professionals
students learning outcome measures
professionals using Measurz or MAT for structured progress tracking
It may be relevant for clients with:
shoulder pain
rotator cuff-related shoulder pain
subacromial pain syndrome
frozen shoulder / adhesive capsulitis
shoulder osteoarthritis
shoulder stiffness
post-operative shoulder recovery
shoulder pain affecting dressing, sleep, lifting or overhead activity
The SPADI is widely used across shoulder pathology and has been studied in shoulder pain populations, including community shoulder pain, frozen shoulder and subacromial pain syndrome.
Use the SPADI when you want to understand how shoulder pain affects daily function.
It may be useful at:
initial assessment
onboarding
reassessment
flare-up review
return-to-gym monitoring
return-to-work monitoring
return-to-overhead activity planning
post-operative milestones
progress review
discharge or long-term follow-up
The SPADI 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
the shoulder is not the main limiting region
many items are missing
the score is being used as a diagnosis
the score is being used as a pass/fail activity decision
the result is interpreted without physical assessment context
The SPADI should not be used to:
diagnose rotator cuff injury
diagnose subacromial pain syndrome
diagnose frozen shoulder
confirm structural shoulder pathology
determine tissue healing
identify the exact pain source
clear someone for work, training or sport
replace professional judgement
replace medical assessment where needed
SPADI questionnaire
Scoring guide or calculator
Measurz recording workflow
Client-reported symptom notes
Baseline and retest dates
Optional related physical tests, such as:
shoulder range of motion
shoulder strength testing
pain with resisted movement
overhead reach assessment
behind-back reach assessment
scapular control observation
work or sport exposure notes
sleep position notes where relevant
Explain the purpose of the questionnaire before the client completes it.
Example wording:
“This questionnaire helps us understand how your shoulder pain is affecting daily activities such as reaching, dressing, washing, carrying and sleep. It does not diagnose the cause of the pain, but it helps us monitor how your function changes over time.”
The SPADI 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 shoulder problem
rate each pain and disability item
answer every item where possible
choose the rating that best reflects their current difficulty
ask for clarification if they do not understand an item
complete the same version at each retest
Record whether the SPADI was completed:
independently
digitally
on paper
verbally
with assistance
This supports repeatability and helps interpret change over time.
If assistance is needed:
explain instructions without leading the answer
avoid telling the client which score to choose
record that assistance was provided
use the same assistance approach at retest where possible
Do not guess missing responses.
SPADI scoring guidance commonly requires a minimum number of items within each subscale to calculate scores. The Shirley Ryan AbilityLab notes that at least two-thirds of items in each subscale must be answered to compute a score.
A factor-structure study also states that if more than two items of a subscale are not answered, no SPADI score is calculated.
For Measurz recording, note:
missing pain items
missing disability items
whether the subscale was still scoreable
whether the total score was calculated
whether the same version was used at retest
The SPADI has 13 items:
5 Pain items
8 Disability items
Each item is commonly rated from 0 to 10, or on a visual analogue scale depending on the version.
Scores are transformed to a 0–100 scale.
General scoring direction:
0: no shoulder pain or disability
100: maximum shoulder pain or disability
Common scoring approach:
Pain subscale = average or transformed score of the 5 pain items
Disability subscale = average or transformed score of the 8 disability items
Total SPADI = average of the Pain and Disability subscales, or total item transformation depending on scoring format
Use the scoring method attached to the specific version being used.
Retest at meaningful points, such as:
baseline
after a rehabilitation block
after a flare-up
before return to overhead training
before return to work demands
after a change in gym or sport load
post-operative milestones
discharge or progress review
For consistency, record:
date
recent flare-ups
current pain behaviour
current work demands
current training exposure
overhead activity exposure
sleep impact
medication changes if relevant and appropriate
any major changes in daily or sport demands
The SPADI 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
major sleep disruption
worsening function
new neurological symptoms
major loss of shoulder motion
major quality-of-life impact
The SPADI produces Pain, Disability and total scores from 0 to 100.
Higher scores indicate greater reported shoulder pain and disability.
Lower scores indicate less reported shoulder pain and disability.
0: no reported shoulder pain or disability
100: maximum reported shoulder pain or disability
A higher SPADI score may suggest:
greater shoulder pain
greater difficulty with daily shoulder tasks
reduced overhead tolerance
reduced carrying or pushing tolerance
more sleep-related shoulder impact
lower confidence using the affected arm
A lower SPADI score may suggest:
less reported shoulder pain
better daily function
better tolerance of reaching, washing, dressing or carrying
less disability related to shoulder symptoms
Look at Pain and Disability subscales separately.
Examples:
High Pain and high Disability may suggest symptoms are strongly limiting function.
High Pain but lower Disability may suggest the client is still functioning despite pain.
Lower Pain but higher Disability may suggest stiffness, weakness, fear, confidence or exposure limits may be contributing.
Improving Disability with persistent Pain may suggest better function despite ongoing symptoms.
A SPADI score does not prove:
the diagnosis
the pain source
rotator cuff integrity
frozen shoulder stage
tendon healing
structural severity
readiness to return to work, gym or sport
whether imaging is required
whether one intervention caused the change
Example wording:
“Your SPADI score suggests your shoulder pain and disability are still affecting daily activities, especially reaching and dressing. This does not tell us exactly what structure is causing the pain, but it helps us track whether your shoulder function is improving over time.”
For general fitness clients, SPADI may help show how shoulder pain affects:
reaching
dressing
washing
carrying
pushing
sleep
gym participation
Interpretation cautions:
recent training may influence answers
fear of movement may affect responses
neck, elbow or hand symptoms may also influence disability
For athletes, SPADI can track general shoulder pain and disability, but it may not capture sport-specific performance demands.
Interpretation should also include:
sport-specific movement testing
overhead exposure
throwing or serving exposure where relevant
gym load
contact or collision exposure where relevant
confidence with training
pain response to sport tasks
A low SPADI score should not be treated as sport clearance on its own.
For older adults, SPADI can help monitor how shoulder pain affects:
dressing
washing
sleep
reaching
carrying
household activity
independence
Interpretation cautions:
other health conditions may influence scores
cervical symptoms may affect shoulder function
general strength and mobility may influence responses
SPADI is more commonly used in adult shoulder pain contexts.
For youth clients, consider:
reading level
comprehension
parent or guardian assistance
sport and school demands
whether a youth-specific or sport-specific measure may be more appropriate
If assistance is provided, record it clearly.
SPADI is commonly used in rotator cuff-related shoulder pain and subacromial pain syndrome contexts. A 2025 study specifically examined reliability, construct validity, responsiveness and MCID of SPADI in subacromial pain syndrome.
Interpretation should also consider:
painful arc or movement response
shoulder range of motion
shoulder strength
resisted testing response
sleep impact
overhead load exposure
SPADI has been studied in idiopathic frozen shoulder. A 2023 study assessed reliability and validity in 124 people with idiopathic frozen shoulder and included a retest subgroup after 7 days.
Interpretation should consider:
shoulder range of motion
irritability
sleep pain
stage of presentation
activity exposure
related physical findings
For post-operative shoulder clients, SPADI can help monitor self-reported pain and disability over time.
Interpretation should consider:
surgery type
healing stage
restrictions
expected post-operative symptoms
activity exposure
medical or surgical guidance where relevant
Meaningful change helps interpret whether a SPADI change is likely to matter.
Key terms:
MCID / MIC: the smallest change that may be meaningful to clients or professionals, depending on 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 questionnaire to detect change over time
PASS: patient acceptable symptom state
SCB: substantial clinical benefit
SPADI meaningful change values vary by condition, baseline severity, scoring version and setting.
A 2019 systematic review examined MCID values for commonly used patient-reported outcomes in shoulder surgery and concluded that consensus for MCID in shoulder PROMs had not been established. This supports using context-specific thresholds rather than one universal value.
A 2025 study examined SPADI reliability, construct validity, responsiveness and MCID in people with subacromial pain syndrome, reflecting ongoing work to define condition-specific clinically meaningful change.
When interpreting SPADI change:
compare Pain, Disability and total scores with baseline
consider whether change exceeds available MCID/MIC or MDC values for the relevant population
check which functional tasks improved
check whether activity exposure has increased
consider pain, sleep, range of motion, strength and overhead function
avoid over-interpreting very small changes
Reported meaningful change values may vary by:
rotator cuff-related pain
frozen shoulder
shoulder osteoarthritis
post-operative shoulder recovery
baseline severity
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
Broad universal SPADI normative values are limited.
The SPADI is best interpreted through practical comparison rather than strict norms.
Use:
baseline comparison
retest comparison
subscale comparison
item-level task changes
client goals
activity exposure
pain and symptom response
related physical assessment findings
Practical guidance:
Scores closer to 0 generally suggest lower reported shoulder pain and disability.
Higher scores suggest greater reported shoulder pain and disability.
A score change is more meaningful when it exceeds measurement error or MIC/MCID values for a matching population.
Improvement should align with daily function and activity exposure.
Avoid using a score alone as a return-to-work, return-to-gym or return-to-sport decision.
Comparison should consider:
age
work demands
activity level
shoulder condition
symptom duration
language version
pain irritability
sleep impact
sport or gym exposure
surgical status
The SPADI has substantial evidence supporting its use as a shoulder pain and disability measure.
A 2006 study of community volunteers with shoulder pain found that SPADI demonstrated factor, construct and longitudinal validity, supporting its use in shoulder pain assessment and monitoring.
A 2009 factor-structure study stated that SPADI is a self-administered instrument designed to measure pain and disability associated with shoulder disease, with 5 pain and 8 disability items, and confirmed scoring on a 0–100 scale.
A responsiveness study reported that SPADI was suitable as an outcome measure in similar shoulder pain settings and described the total score as ranging from 0 best to 100 worst.
Reliability and validity are stronger when:
the correct SPADI version is used
the correct language version is used
all required items 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 items are missing
the client has difficulty understanding items
symptoms are not primarily shoulder-related
neck or upper limb symptoms drive limitation
the score is used as a stand-alone diagnostic or clearance decision
the language version has limited validation evidence
Common errors include:
treating SPADI as a diagnosis
using SPADI as return-to-work, return-to-gym or return-to-sport clearance
mixing VAS and numeric rating versions across retests
ignoring missing items
not recording completion method
over-interpreting small changes
using broad categories as strict cut-offs
interpreting shoulder function without activity exposure
failing to pair it with physical testing
Limitations include:
self-report can be influenced by mood, expectations and recent activity
scores do not identify the exact physical cause of symptoms
meaningful change values vary across conditions
universal normative values are limited
SPADI may not capture sport-specific performance well
neck, elbow or hand symptoms may influence responses
it should be paired with physical assessment and client goals
The SPADI may help professionals:
document baseline shoulder pain and disability
identify whether pain or disability is more 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, SPADI can show whether shoulder pain is affecting pressing, pulling, carrying, reaching or gym participation.
For workplace clients, SPADI can help track disability related to lifting, carrying, overhead work and daily tasks.
For persistent shoulder pain, SPADI can help monitor whether disability is improving even if pain fluctuates.
For Measurz users, SPADI is most useful when combined with practical measures such as:
shoulder range of motion
shoulder strength
pain with resisted movement
overhead reach
behind-back reach
scapular control
lifting tolerance
sleep impact
work or training exposure
Record:
outcome measure name: Shoulder Pain and Disability Index / SPADI

completion method: paper, digital, interview or assisted
language/version used
condition or presentation being tracked
side involved: left, right or bilateral
Pain subscale score
Disability subscale score
Total SPADI score
score range: 0–100
direction of scoring: higher score indicates greater pain and disability
missing pain items, if any
missing disability items, if any
whether score was calculable
assistance provided, if any
current pain score, if relevant
current symptoms
sleep impact
current work, gym or sport exposure
key functional limitations
confidence or participation goals
baseline comparison
MCID/MIC/MDC comparison where supported
item-level tasks that improved or worsened
related physical assessment findings
interpretation notes
retest date
referral or further assessment notes where appropriate
Record whether the main limitation appears to be:
pain dominant
disability dominant
overhead reaching limitation
behind-back reach limitation
dressing or washing limitation
carrying or pushing limitation
sleep-related limitation
mixed limitation
unclear due to incomplete responses
This improves:
repeatability
communication
client education
assessment reasoning
monitoring over time
team consistency
reporting quality
The SPADI measures self-reported shoulder pain and shoulder-related disability.
The SPADI has 13 items: 5 pain items and 8 disability items.
SPADI is usually scored from 0 to 100 for Pain, Disability and total score. Higher scores indicate greater shoulder pain and disability.
Yes. Higher SPADI scores indicate greater reported pain and disability.
No. SPADI measures shoulder pain and disability. It does not diagnose rotator cuff injury, frozen shoulder, subacromial pain or any other specific condition.
Meaningful change values vary by population and shoulder condition. Use condition-specific MCID or MDC values where available and interpret change alongside baseline score, symptoms, function and activity exposure.
It can track general shoulder pain and 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 or return-to-training planning, and at progress review.
The Shoulder Pain and Disability Index is a 13-item shoulder outcome measure.
It includes a 5-item Pain subscale and an 8-item Disability subscale.
Scores are usually reported from 0 to 100.
Higher scores indicate greater shoulder pain and disability.
SPADI does not diagnose the cause of shoulder pain or clear a client for activity.
Meaningful change values vary by shoulder condition and population.
Broad normative values are limited, so baseline comparison is usually most useful.
Measurz should record version, Pain score, Disability score, total score, completion method, missing items, side, activity exposure, baseline comparison, item-level changes and related physical findings.
