# How do you interpret a lower extremity functional scale?

## How do you interpret a lower extremity functional scale?

LEFS score = SUM (points for all 20 activities) Interpretation: Minimum score: 0 Maximum score: 80 The lower the score the greater the disability. The Minimal Detectable Change (MDC) is 9 scale points. The Minimal clinically Important Difference (MCID) is 9 scale points.

## What is a good LEFS score?

They found a mean LEFS score of 71, indicating a good result of their treatment. When less than 15% of the individuals have the minimum score, no floor effect is present, and when less than 15% reach the maximum score, there is no ceiling effect (McHorney and Tarlov 1995).

Who created the lower extremity functional scale?

Binkley et al5
Binkley et al5 developed the Lower Extremity Functional Scale (LEFS) as a patient-reported measure to examine the functional status in the presence of lower extremity musculoskeletal problems. The LEFS consists of 20 items, with scores ranging from 0 (extreme difficulty/unable to perform activity) to 4 (no difficulty).

### What is the MCID for LEFS?

The MCID for the LEFS has been previously reported as 9 points. However, this MCID was established for patients with a variety of lower extremity conditions and the study did not include any subjects with Achilles tendinopathy. Therefore, a specific MCID for Achilles tendinopathy may be useful.

### What is the purpose of the LEFS?

The LEFS can be used to evaluate the functional impairment of a patient with a disorder of one or both lower extremities. It can be used to monitor the patient over time and to evaluate the effectiveness of an intervention. The columns on the scale are summed to get a total score. The maximum score is 80.

How do you read a DASH score?

Use a calculator Add up the points marked by the patient Subtract 30 Divide by 1.2 The answer is the DASH score. The response to the first 30 items of the DASH are added to form the raw, or ac- tual, score. For example, if a patient an- swered 2, or Mild Difficulty, to all 30 ques- tions, the raw score would be 60.

## What is LEFS outcome measure?

The Lower Extremity Functional Scale (LEFS) is a questionnaire containing 20 questions about a person’s ability to perform everyday tasks. The LEFS can be used by clinicians as a measure of patients’ initial function, ongoing progress and outcome, as well as to set functional goals.

## How do you score a Knee outcome Survey?

Each item is scored 0-5 with 5 indicating “no difficulty” and 0 representing “unable to perform”. The highest possible score is 70. The scores of all items are summed, divided by 70, then multiplied by 100 to give an overall ADLS percent rating. Higher percentages reflect higher levels of functional ability.

What is the DASH outcome measure?

Go to DASH website. Published: January 1996. The DASH (Disabilities of the Arm, Shoulder and Hand) Outcome Measure is a 30-item, self-report questionnaire that measures physical function and symptoms in people with musculoskeletal disorders of the upper limb.

### What is a functional scale?

Patient Specific Functional Scale was developed by Stratford et al 1995 as a self-report outcome measure of function that could be used in patients with varying levels of independence.

### How do you score UEFS?

The UEFS consists of 8 questions, that are scored out of a possible 10 points. The scale is calculated by summing the points from each individual question, with a range of 0 (no disability) to 80 (maximum disability).

What is the highest DASH score?

100
The DASH Questionnaire The scores are then used to calculate a scale score ranging from 0 (no disability) to 100 (most severe disability)—this is called the DASH score.

## How valid is the lower extremity functional scale?

Concurrent validity of the Lower Extremity Functional Scale was excellent compared with the Olerud Mo- lander Ankle Score at the short- and medium-term follow-ups ( r = 0.80 and 0.87, respectively).

## What is the normal range of lefs scores?

Results: The ICC of the LEFS was 0.88, and the SEM was 4 LEFS points (LEFS score range, 0-80). The change in LEFS correlated with changes of comparison measures in the same direction of improvement. Patients rated as improved by both themselves and their therapists had significantly larger change in LEFS scores than subjects rated as no change.

What is the correlation between the lefs and Berg Balance Scale?

Adequate to Excellent correlation between the LEFS and the Short Form 36 Function Scale, Berg Balance Scale, Six Minute Walk Test, Five Meter Walk Test, Timed Up and Go Test, and the LAS of function ( r = 0.40 – 0.71) (Young et al, 2009; n = 91 subjects with a primary complaint of neck pain and with or without concomitant upper extremity symptoms)

### What is the purpose of a limb function test?

The test can be used to evaluate the impairment of a patient with lower extremity musculoskeletal condition or disorders. Can be used clinically to measure the patients’ initial function, ongoing progress, and outcome as well as to set functional goals.
