Lower Extremity Functional Scale (LEFS)

The Lower Extremity Functional Scale asks how hard 20 everyday activities are because of a hip, knee, ankle, or foot problem. Each scores 0 to 4, and the total, from 0 to 80, measures lower limb function: higher is better, and a change of 9 points is real. See how to read a score, work out percent of maximal function, set goals in LEFS points, and record the result with the free template.

What the score means. 0 to 80, function score, higher means better function.

0 to 20: Severe limitation

Most everyday activities are very hard or not possible. Common in the first days after major surgery or a serious injury: work on safe transfers, walking with an aid, and pain control, and score again within 2 weeks.

21 to 40: Moderate limitation

Getting around the home is possible, with effort; longer walks, stairs, and standing for long are hard. Typical early in rehab. Set short-term goals in points and build toward walking in the community.

41 to 60: Mild limitation

Most daily tasks are manageable. Difficulty remains with heavier work around the home, longer walks, and sport. Aim treatment at the activities the patient still finds hardest.

61 to 80: Minimal or no limitation

Little or no difficulty with daily activities; most healthy adults score in this range. Plan discharge to a home program, and for athletes, add sport-specific tests before return to sport.
  • Add the 20 item scores, each 0 to 4, for a total from 0 to 80. Higher means better function, the opposite direction from the QuickDASH, the WOMAC, and the Oswestry.
  • Percent of maximal function is the total divided by 80, times 100. A score of 52 is 65% of maximal function.
  • The developers published no severity bands. The four bands here are descriptive quarters of the range, to help read a score; track the change and the goals rather than the band.
  • In the original study, the error around a single score was ±5.3 points at 90% confidence, and both the minimal detectable change and the minimal clinically important difference were 9 points. A rise of 9 or more is real and matters to the patient.
  • Studies after hip and knee replacement and after ACL reconstruction found much the same, about 9 points. One study of hip conditions put the smallest important change a little lower, at about 6 points.
  • Healthy adults score high: a study of over 1,000 adults found a median of 77, men slightly higher than women, falling with age. A goal of 80 isn’t right for every patient.
  • The LEFS has a ceiling. Very active people can score in the high 70s before they’re ready for sport, so add hop, strength, and sport-specific tests near the top of the range.
  • Use it for any lower limb musculoskeletal condition, at any joint and from any cause, from hip arthritis to an ankle sprain. It has also been studied in inpatient rehab and after stroke.
  • It gives one score for the person, not one per leg. Record which side or sides are affected, so later scores are read in context.
  • The original paper gives no rule for blank items. Ask any blank before the patient leaves; if your protocol prorates a form with a blank, record that the score was prorated and how many items were missing.

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

Giving it

The patient completes the official form alone, rating how much difficulty their lower limb problem causes with each activity at present. It takes about 5 minutes.

  • Use the official form in the patient’s language, with its own instructions
  • For an activity they don’t usually do, the patient rates the difficulty they think they would have
  • Give it at the first visit, before treatment starts, so there is a true baseline
  • Read the form aloud word for word when reading is hard

Avoid: Filling it in for the patient from what you saw in the session. The LEFS records the patient’s own view of their function.

Scoring

Each of the 20 activities scores from 0, extremely hard or not possible, to 4, no difficulty. Add them for a total from 0 to 80.

  • Check that all 20 items are answered before the patient leaves
  • Work out percent of maximal function: the total divided by 80, times 100
  • Record the total, the percent, and the activities that lost the most points

Avoid: Reading a falling score as progress. On the LEFS, higher is better.

Reading the score

The total shows how much the problem limits daily life; the item scores show where.

  • Name the band next to the total, and say it is descriptive
  • Look at which activities still lose points, and match treatment to them
  • Weigh the score against what you measured: range of motion, strength, gait, and balance

Avoid: Treating one score as exact. A single LEFS score carries an error of about 5 points either way.

Tracking change

Score it at the evaluation, every 2 to 4 weeks or at each progress report, and at discharge.

  • Use the same form, given the same way, each time
  • A rise of 9 points or more from baseline is real, meaningful change
  • A change under 9 points may be measurement error; look at the trend over several scores
  • Review the plan when the score hasn’t risen 9 points in 4 to 6 weeks

Setting goals

Write goals as a target score tied to an activity that matters to the patient, with a date.

  • Short-term goals at least 9 points above baseline, so reaching one is a real change
  • Long-term goals from the patient’s work, sport, or daily role, not a fixed 80
  • For athletes, pair the score with hop, strength, and running tests before return to sport

Avoid: Discharging on the score alone when the patient can’t yet do the activity the goal stands for.

LEFS result: progress report 10 weeks after a total knee replacement

Outpatient physical therapy, progress report at visit 14

Lower limb problem

58-year-old school librarian. Right total knee replacement for osteoarthritis 10 weeks ago; first seen here at week 2. Back at work 3 days a week, where she is on her feet most of the day and shelves books from floor to head height.

Score today

LEFS 52 out of 80, all 20 items answered: 65% of maximal function, mild limitation. Most points lost on the demanding activities: a full flight of stairs without the rail, getting down to the floor, and walking more than about 20 minutes. Knee bends to 112° and straightens to 3° short of full. Walks without a cane.

Change

Baseline 24 at week 2: 30%, moderate limitation. Up 28 points, three times the 9-point minimal clinically important difference: real, meaningful improvement. 41 at week 6, so up 11 since the last score.

Goals

Short-term, set at week 2: LEFS 40 and walking indoors without the cane by week 6. Met at week 6. Long-term: LEFS 65 and full shifts at work, with stairs foot over foot, by week 16. On track.

Plan

Twice weekly for 4 more weeks: quadriceps strengthening, step-ups and step-downs, floor transfers, and walking endurance, with the home program progressed. LEFS again at week 14. Discharge to the home program when she reaches 65 and works full shifts.

Common mistakes, and how to avoid them.

Reading the score the wrong way round

On the LEFS, higher is better. On the QuickDASH, the WOMAC, and the Oswestry, higher is worse. Write “improved” only when the LEFS rises.

Calling a small change progress

A rise of 4 or 5 points can be measurement error. Report 9 points or more as real change, and look at the trend across scores.

Using the bands as cutoffs

The developers set no severity bands. Read the total, the change from baseline, and the activities still lost, not only which quarter of the range it falls in.

Clearing an athlete on the score

A runner can score 76 and still not be ready to race. Near the top of the range, add hop, strength, and running tests.

Scoring each leg apart

The LEFS gives one score for the person. When both legs are affected, record both sides, and give the form once.

Using a retyped copy

Reworded versions circulate online and aren’t validated. Use the official form and its translations, so scores compare across visits and clinics.

Frequently asked questions.

How do you score the LEFS?

Each of the 20 activities scores from 0, extremely hard or not possible, to 4, no difficulty. Add them for a total from 0 to 80. Higher means better function. Check that every item is answered before the patient leaves.

How do you work out the LEFS percentage?

Divide the total by 80 and multiply by 100. That gives percent of maximal function: a score of 52 is 65%, and a score of 24 is 30%. Some clinics also report percent limitation, which is 100 minus that figure; say which one you recorded.

What does an LEFS score mean?

The higher the score, the less the lower limb problem limits daily life. The developers set no official bands; a common descriptive reading is 0 to 20 severe, 21 to 40 moderate, 41 to 60 mild, and 61 to 80 minimal or no limitation. Healthy adults usually score in the high 70s, with a median of about 77 in one large study.

What is the MCID for the LEFS?

About 9 points. In the original study, both the minimal detectable change and the minimal clinically important difference were 9 points, and studies after joint replacement and ACL reconstruction found much the same. The error around a single score is about 5 points either way.

What is the difference between the LEFS and the KOOS or WOMAC?

The LEFS covers the whole lower limb, so one form works for a hip, knee, ankle, or foot problem, and higher is better. The KOOS is knee-specific, with five subscales scored 0 to 100. The WOMAC is built for hip and knee osteoarthritis, with pain, stiffness, and function scores where higher is worse. Many clinics use the LEFS across all lower limb patients and a joint-specific measure alongside it.

Is there an upper limb version of the LEFS?

Yes. The Upper Extremity Functional Index, from the same research group, uses the same format: 20 activities, scored 0 to 80, higher is better. Many clinics use the DASH or the shorter QuickDASH instead, scored 0 to 100, where higher means more disability.

Show all questions
Who can give the LEFS?

The patient completes it themselves, in about 5 minutes, and no training is needed to give or score it. Physical therapists use it most, but any clinician can hand it out, score it, and read it alongside the exam.

What activities does the LEFS ask about?

Twenty everyday activities, from tasks around the home and getting around to higher-demand ones such as sport. The exact wording, with its translations, is on the official form from Mapi Research Trust’s ePROVIDE site. Use that form rather than a retyped copy, as altered versions aren’t validated.

Is the LEFS free?

The Shirley Ryan AbilityLab’s RehabMeasures database lists the LEFS as free to use, and the copyright is held by the American Physical Therapy Association. The official form and 19 translations are listed on Mapi Research Trust’s ePROVIDE site, with the conditions of use, after a free sign-up. Check them before using it in research, a publication, or software. The recording template on this page is free to copy or download.
