The Upper Extremity Functional Index, or UEFI, is a patient-reported outcome measure used to assess upper limb function across shoulder, elbow, wrist and hand presentations. The original version includes 20 items scored from 0 to 4, producing a total score from 0 to 80, where higher scores indicate better reported upper limb function. The UEFI can support baseline assessment and progress tracking, but it does not diagnose the cause of symptoms or clear someone for work, training or sport on its own.

Introduction

Upper limb problems can affect reaching, lifting, carrying, dressing, grooming, gripping, pushing, pulling, work tasks, sport and gym training.

The Upper Extremity Functional Index, commonly called the UEFI, is a patient-reported outcome measure designed to assess functional difficulty related to upper limb musculoskeletal conditions.

It is commonly used for:

• shoulder symptoms
• elbow symptoms
• wrist symptoms
• hand symptoms
• upper limb injury monitoring
• post-operative upper limb recovery
• rehabilitation progress tracking
• return-to-work monitoring
• return-to-gym or sport monitoring
• broad upper limb functional assessment

The original UEFI is a 20-item questionnaire. Each item is rated from 0 to 4, giving a total score from 0 to 80. Higher scores indicate better upper limb function.

• Key limitation: UEFI does not diagnose the cause of symptoms or determine return-to-activity readiness on its own

What Is the Upper Extremity Functional Index?

The UEFI is an upper limb patient-reported outcome measure.

It asks the client to rate how much difficulty they have with common upper limb activities because of their current upper limb problem.

The scale is commonly used across upper limb regions, including:

• shoulder
• arm
• elbow
• forearm
• wrist
• hand

The original UEFI has 20 questions scored on a 5-point rating scale. It was developed to assess function in people with upper extremity musculoskeletal conditions. A later Rasch-validated version, the UEFI-15, was developed to improve interval-level measurement properties.  

Why It Is Used

The UEFI is used because upper limb function is not always fully explained by physical tests alone.

A client may show improving range of motion or strength but still report difficulty with:

• lifting groceries
• reaching overhead
• carrying objects
• dressing
• washing or grooming
• pushing or pulling
• gripping
• opening doors or containers
• household tasks
• work tasks
• sport or gym activities

The UEFI can help professionals:

• establish a functional baseline
• quantify self-reported upper limb function
• monitor change over time
• identify activity limitations
• support client education
• guide goal-setting conversations
• compare subjective progress with physical testing
• improve progress reporting in Measurz

The UEFI should support assessment reasoning and monitoring. It should not be used as a stand-alone diagnostic, treatment or clearance tool.

What It Measures

The UEFI measures perceived difficulty with upper limb functional activities.

It may provide insight into:

• reaching tolerance
• lifting tolerance
• carrying tolerance
• pushing and pulling function
• gripping and handling tasks
• dressing and grooming tasks
• household activity
• work function
• sport and recreation participation
• confidence using the affected arm

It does not directly measure:

• shoulder range of motion
• grip strength
• rotator cuff integrity
• tendon healing
• ligament integrity
• nerve function
• fracture healing
• tissue healing
• readiness to return to sport
• readiness to return to work

Who It Is Useful For

The UEFI 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
• elbow pain
• wrist pain
• hand pain
• upper limb injury
• rotator cuff-related shoulder pain
• tennis elbow or golfer’s elbow presentations
• post-operative upper limb recovery
• upper limb fracture recovery
• reduced confidence with reaching, lifting, carrying or gripping
• work-related upper limb limitations

The UEFI is broad rather than diagnosis-specific, which makes it useful when the main aim is to monitor upper limb function across different presentations.

When to Use This Outcome Measure

Use the UEFI when you want to understand how an upper limb problem affects the client’s daily activity and physical function.

It may be useful at:

• initial assessment
• onboarding
• reassessment
• flare-up review
• post-injury monitoring
• post-operative milestones
• return-to-lifting planning
• return-to-work planning
• return-to-gym planning
• return-to-sport planning
• discharge or progress review

The UEFI is most useful when repeated over time using the same version and scoring method.

When Not to Use or When to Be Cautious

Use caution when:

• the client cannot complete the questionnaire independently
• language or literacy affects responses
• the wrong language version is used
• multiple body regions are driving limitation
• the client has not attempted the activities being scored
• many items are missing
• the score is being used as a diagnosis
• the score is being used as a pass/fail return-to-activity decision
• a region-specific shoulder, elbow, wrist or hand outcome measure may be more appropriate

The UEFI should not be used to:

• diagnose an upper limb condition
• confirm injury
• determine tissue healing
• identify the exact cause of symptoms
• clear someone for work, training or sport
• replace physical assessment
• replace professional judgement

Equipment or Resources Required

• UEFI questionnaire
• UEFI-15 questionnaire if using the Rasch-validated short version
• 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
  • elbow range of motion
  • wrist or hand range of motion
  • upper limb strength testing
  • grip strength testing
  • pain with resisted movement
  • overhead reach assessment
  • behind-back reach assessment
  • carrying or lifting assessment
  • work or sport exposure notes

Administration Protocol / Practice

Setup

Explain the purpose of the questionnaire before the client completes it.

Example wording:

“This questionnaire helps us understand how your upper limb symptoms are affecting activities such as reaching, lifting, carrying, gripping and daily tasks. It does not diagnose the cause of symptoms, but it helps us monitor your function over time.”

Format

The UEFI can be completed:

• on paper
• digitally
• independently
• verbally if assistance is needed
• before a session
• during reassessment
• as part of a Measurz workflow

Client Instructions

Ask the client to:

• answer based on their current upper limb problem
• rate difficulty for each activity
• answer every item where possible
• choose the number that best reflects their current difficulty
• ask for clarification if they do not understand an item
• complete the same version at each retest

Completion Method

Record whether the UEFI was completed:

• independently
• digitally
• on paper
• verbally
• with assistance

This supports repeatability and helps interpret change over time.

Assistance Rules

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

Missing Item Handling

Do not guess missing responses.

For best practice:

• encourage completion of all items
• record any missing item
• avoid comparing scores if missing-item handling differs between sessions
• record whether the score was calculated from a complete or incomplete form
• interpret incomplete scores cautiously

Scoring Process: Original UEFI

The original UEFI includes 20 items.

Each item is scored from:

• 0: extreme difficulty or unable to perform activity
• 1: quite a bit of difficulty
• 2: moderate difficulty
• 3: a little bit of difficulty
• 4: no difficulty

Total score range:

• Minimum: 0
• Maximum: 80

Scoring direction:

• Higher score: better reported upper limb function
• Lower score: greater reported upper limb limitation

Scoring Process: UEFI-15

The UEFI-15 is a Rasch-validated shorter version.

Because UEFI-15 scoring and interpretation may differ from the original 20-item UEFI, record the version clearly and avoid comparing raw UEFI-15 and UEFI-20 scores as if they are interchangeable. The UEFI-15 was developed after Rasch analysis showed that the original 20-item version had measurement issues for interval-level interpretation.  

Retesting Considerations

Retest at meaningful points, such as:

• baseline
• after a rehabilitation block
• after a flare-up
• before return to lifting
• before return to overhead activity
• before return to work
• before return to sport
• after a change in training load
• post-operative milestones
• discharge or progress review

For consistency, record:

• date
• current pain behaviour
• current reaching exposure
• current lifting or carrying exposure
• current work demands
• recent flare-ups
• current training or sport load
• any major changes in activity demands

Safety Notes

The UEFI is a self-report questionnaire, so it does not create physical testing risk.

However, worsening responses may support further assessment where the client reports:

• major functional decline
• worsening reaching tolerance
• worsening grip or carrying tolerance
• new neurological symptoms
• increased swelling or pain
• inability to complete usual activities

Scoring and Interpretation

The original UEFI produces a total score from 0 to 80.

Higher scores indicate better reported upper limb function.

Lower scores indicate greater reported limitation.

Score Range

• 0: extreme difficulty or unable to perform all activities
• 80: no difficulty across all activities

What a High Score May Suggest

A higher UEFI score may suggest:

• better upper limb function
• less difficulty with daily tasks
• better reaching tolerance
• better lifting and carrying tolerance
• better grip or handling confidence
• improved confidence using the affected arm

What a Low Score May Suggest

A lower UEFI score may suggest:

• greater upper limb functional limitation
• difficulty with daily or higher-demand tasks
• reduced reaching, lifting or carrying tolerance
• reduced work, gym or sport capacity
• lower confidence using the upper limb

What the Score Does Not Prove

A UEFI score does not prove:

• the diagnosis
• the tissue source of symptoms
• severity of structural injury
• readiness to return to sport
• readiness to return to work
• whether imaging is required
• whether one intervention caused the change

How to Explain the Result Safely

Example wording:

“Your UEFI score shows how much difficulty you are currently having with upper limb activities. It does not tell us exactly what structure is causing symptoms, but it helps us track whether your function is improving over time.”

What the Score May Mean in Different Client Populations

General Fitness Clients

For general fitness clients, UEFI may help show how upper limb symptoms affect:

• reaching
• lifting
• carrying
• pushing
• pulling
• gripping
• gym training
• household tasks

Interpretation cautions:

• recent training may influence answers
• pain expectations may affect responses
• neck, thoracic or hand symptoms may influence upper limb function

Sport and Performance Clients

For athletes, UEFI can help track broad upper limb function but may not capture sport-specific performance fully.

Interpretation should also include:

• sport-specific exposure
• throwing, serving or contact exposure where relevant
• overhead strength and endurance
• grip or hand demands
• workload history
• sport-specific confidence
• functional testing

A high UEFI score should not be treated as return-to-sport clearance on its own.

Older Adults

For older adults, UEFI may help monitor how upper limb symptoms affect:

• dressing
• grooming
• household tasks
• carrying
• reaching
• independence
• confidence with daily activity

Interpretation cautions:

• other health conditions may influence scores
• general strength and mobility may affect responses
• assistive devices or support at home may influence function

Youth Clients

UEFI is more commonly used in adult upper limb musculoskeletal contexts.

For youth clients, consider:

• reading level
• comprehension
• sport exposure
• parent or guardian assistance
• whether a youth-specific or sport-specific measure may be more appropriate

If assistance is provided, record it clearly.

Shoulder, Elbow, Wrist and Hand Presentations

UEFI can be used across the upper limb, but region-specific tools may provide more detail.

Consider pairing UEFI with:

• SPADI for shoulder pain and disability
• Oxford Shoulder Instability Score for shoulder instability
• grip strength testing for hand or wrist presentations
• region-specific measures where available and relevant

Post-Surgical Clients

For post-operative clients, UEFI can help track perceived upper limb function over time.

Interpretation should consider:

• surgery type
• healing stage
• restrictions
• expected symptom response
• activity exposure
• medical or surgical guidance where relevant

Clients Returning After Injury

For clients returning after injury, UEFI can help show whether daily and higher-demand function is improving.

However:

• high UEFI scores should not automatically be treated as clearance
• task-specific capacity should still be tested
• strength, range of motion, grip, load tolerance and workload measures should be considered

Meaningful Change, MCID, MDC and Responsiveness

Meaningful change helps determine whether a UEFI score 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: estimated measurement error around a score
• Responsiveness: ability of the questionnaire to detect change over time

UEFI Meaningful Change Evidence

A 2018 clinimetric summary reported that the UEFI has demonstrated strong measurement properties across clinical populations and that an MCID of 8 points out of 80 has been reported for shoulder, elbow, wrist and hand musculoskeletal conditions.  

A 2014 study evaluated reliability and validity of two UEFI versions, and ePROVIDE lists the original UEFI and UEFI-15 with related validation research.  

Practical Interpretation

When interpreting UEFI change:

• compare the total score with baseline
• use the same UEFI version at retest
• consider whether change exceeds available MCID or MDC values for a matching population
• check which activities improved
• check whether activity exposure has increased
• consider pain, swelling, range of motion, strength and grip findings
• avoid over-interpreting very small changes

When Values Are Uncertain

Reported meaningful change values may vary by:

• upper limb region
• condition
• language version
• surgical versus non-surgical context
• baseline score
• follow-up timeframe
• activity exposure
• scoring version

When no matching MCID, MDC or SEM value exists, interpretation should rely more heavily on:

• baseline comparison
• repeated measurement
• client-reported change
• activity exposure
• related physical assessment findings
• professional judgement

Normative Data, Reference Values or Comparative Data

Broad universal UEFI normative values appear limited.

The UEFI is best interpreted through practical comparison rather than strict norms.

Use:

• baseline comparison
• retest comparison
• item-level task change
• client goals
• activity exposure
• pain and symptom response
• related physical assessment findings

Practical guidance:

• Scores closer to 80 generally suggest better reported upper limb function.
• Lower scores suggest greater reported functional limitation.
• A score change is more meaningful when it exceeds measurement error or 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
• upper limb region
• symptom duration
• language version
• pain irritability
• surgical status
• sport or gym exposure
• dominant side involvement

Reliability and Validity

The UEFI has post-2000 evidence supporting its use as an upper limb function measure.

A 2018 clinimetric summary described the UEFI as a 20-item, region-specific patient-reported outcome measure developed to measure upper extremity function in people with hand and upper extremity disorders. It also reported excellent test-retest reliability values across samples, including ICC values around 0.94–0.95 in upper extremity musculoskeletal conditions.  

A Rasch validation study found that the original 20-item UEFI had not previously undergone Rasch validation and developed a Rasch-validated version for interval-level measurement of upper extremity function.  

A 2023 systematic review examined the clinical utility and psychometric properties of available UEFI versions, reflecting ongoing evaluation of different versions and their measurement quality.  

Reliability and validity are stronger when:

• the correct UEFI version is used
• the correct language version is used
• all 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 not attempted the activities being scored
• symptoms are from multiple body regions
• the score is used as a stand-alone diagnostic or clearance decision
• UEFI-20 and UEFI-15 scores are compared directly
• the language version has limited validation evidence

Common Errors and Limitations

Common errors include:

• treating UEFI as a diagnosis
• using UEFI as return-to-sport clearance
• using UEFI as return-to-work clearance
• not recording the version used
• comparing UEFI-20 and UEFI-15 raw scores directly
• not recording completion method
• ignoring missing items
• over-interpreting small changes
• interpreting the score 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 populations
• broad upper limb scoring may miss region-specific issues
• sport-specific performance may require additional testing
• high scores do not guarantee readiness for high-speed or high-load activity
• it should be paired with physical assessment and client goals

Practical Applications

The UEFI may help professionals:

• document baseline upper limb function
• identify activities that are most affected
• monitor change over time
• track response during rehabilitation or training modification
• support return-to-lifting discussions
• support return-to-work planning
• guide goal-setting conversations
• improve client education
• strengthen Measurz reports

For fitness clients, UEFI can show whether upper limb symptoms are affecting reaching, lifting, carrying, gripping or gym participation.

For athletes, UEFI can support broad function monitoring but should be paired with sport-specific testing.

For workplace clients, UEFI can help track function related to lifting, carrying, gripping, pushing, pulling and overhead work.

For Measurz users, UEFI is most useful when combined with practical measures such as:

• upper limb range of motion
• shoulder strength
• elbow or wrist strength
• grip strength
• overhead reach
• behind-back reach
• pain with resisted movement
• lifting or carrying tolerance
• work or sport exposure
