Lower Extremity Functional Scale (LEFS)

Introduction

The Lower Extremity Functional Scale (LEFS) is a patient-reported outcome measure (PROM) used to assess lower extremity function in individuals with musculoskeletal disorders or injuries. It is a 20-item questionnaire that evaluates activities of daily living (ADLs) related to standing, walking, balance, and stair climbing.

Each item is scored on a 4-point scale ranging from “0” (unable to do) to “3” (can do without difficulty). Higher scores denote better function. The total score runs from 0 to 80.

One outcome measure used to evaluate the functional status of people with impairments to their lower extremities is the LEFS.

This technique, which covers walking, stair climbing, balancing, and standing, aids in assessing the physical function and disability associated with lower extremity deficits. This is used for measuring a person’s development over time in research projects as well as clinical settings due to its dependability.

The Lower Extremity Functional Scale aids in measuring the degree of difficulty people encounter when carrying out tasks. The score goes from 20 (easy) to 80 (impossible to act).

The Lower Extremity Functional Scale (LEFS) is a valuable tool for assessing lower extremity function and evaluating the effectiveness of treatment interventions in patients with musculoskeletal disorders. It serves several important purposes in clinical practice and research:

1. Measuring Functional Impact: The LEFS quantifies an individual’s ability to perform everyday activities that rely on lower extremity function. This includes tasks like walking, climbing stairs, maintaining balance, and sitting down. By assessing these activities, the LEFS provides insight into how a lower extremity condition affects a person’s daily life.
2. Tracking Functional Progress: The LEFS allows clinicians to monitor changes in functional status over time. This is particularly useful for evaluating the effectiveness of rehabilitation interventions or tracking the progression of chronic conditions. By comparing LEFS scores at different points in time, clinicians can determine whether a patient is improving, maintaining, or experiencing functional decline.
3. Evaluating Treatment Effectiveness: The LEFS serves as a tool to assess the effectiveness of different treatment interventions, such as physical therapy, occupational therapy, or assistive devices. By comparing LEFS scores before and after treatment, clinicians can determine whether a particular intervention has led to improvements in functional status.
4. Informing Patient Care Decisions: LEFS scores provide valuable information that guides patient care decisions. For instance, clinicians can use LEFS scores to determine the level of assistance a patient may need with daily activities, make informed decisions about discharge planning, and establish functional goals for rehabilitation.
5. Assessing Quality of Life: The LEFS indirectly reflects an individual’s quality of life by measuring their ability to perform essential daily tasks. A person’s ability to independently perform these activities contributes significantly to their overall well-being and quality of life.

Overall, the LEFS is a versatile and valuable tool for clinicians and researchers working with individuals with lower extremity impairments. It provides a standardized and reliable measure of functional status, allowing for informed decision-making, treatment evaluation, and patient care planning.

Objective LEFS

The Lower Extremity Functional Scale (LEFS) is a self-reported questionnaire that measures a person’s ability to perform activities of daily living (ADLs) related to lower extremity function. It is a 20-item questionnaire that is scored on a 4-point scale, with higher scores indicating better function. The LEFS is a reliable and valid measure of lower extremity function and has been used in a variety of research studies.

The objective of the LEFS:

• To assess a person’s lower extremity function and ability to perform ADLs.
• To track changes in lower extremity function over time.
• To evaluate the effectiveness of treatment interventions.

The LEFS is a valuable tool for clinicians and researchers working with individuals with lower extremity impairments. It is a reliable, valid, and easy-to-administer measure that can be used to assess functional status, track progress, and evaluate treatment effectiveness.

Here is a table summarizing the objective of the LEFS:

Objective	Description
Assess lower extremity function	The LEFS can be used to assess a person’s ability to perform activities of daily living (ADLs) related to lower extremity function.
Track changes in lower extremity function over time	The LEFS can be used to track changes in a person’s lower extremity function over time. This can be helpful for monitoring the progress of treatment or rehabilitation.
Evaluate the effectiveness of treatment interventions	The LEFS can be used to evaluate the effectiveness of treatment interventions for lower extremity impairments

Scoring the LEFS

The Lower Extremity Functional Scale (LEFS) is scored by assigning points to each item based on the patient’s self-reported ability to perform the activity. Each item is graded on a four-point scale:

• 0: Unable to do
• 1: Can do with assistance
• 2: Can do with some difficulty
• 3: Can do without difficulty

The final score is determined by adding the scores from all 20 items. The maximum possible score is 80, and higher scores indicate better functional status.

Here is an example of how to score the LEFS:

Item	Patient’s Response	Score
Everything you typically do for a job, household, or school.	I can do all of my usual work and activities without difficulty.	3
Your usual hobbies, recreational, or sporting activities.	I can do most of my usual hobbies, but I have some difficulty with strenuous activities.	2
Getting into or out of the bath.	I can get into and out of the bath without assistance, but I need to be careful.	2
Walking on a flat surface.	I can walk on a flat surface for more than 10 minutes without stopping.	3
Walking downstairs.	I can walk up stairs without assistance, but I need to take one step at a time and hold onto the railing.	2
I can walk downstairs without assistance, but I need to be careful and take my time.	I can walk upstairs without assistance, but I need to take one step at a time and hold onto the railing.	2
Standing for more than 10 minutes.	I can stand for more than 10 minutes without discomfort.	3
Sitting for more than 10 minutes.	I can sit for more than 10 minutes without discomfort.	3
Getting out of a chair.	I can get out of a chair without assistance.	3
Putting on shoes and socks.	I can put on my shoes and socks without assistance.	3
Getting dressed.	I can get dressed without assistance.	3
Bathing.	I can bathe myself without assistance.	3
Eating.	I can eat without assistance.	3
Toileting.	I can use the toilet without assistance.	3
Getting in and out of bed.	I can get in and out of bed without assistance.	3

In this example, the patient’s total score is 70. This indicates that the patient has good functional status, but they may have some difficulty with strenuous activities.

Interpretation of LEFS scores

The interpretation of LEFS scores is as follows:

Score	Interpretation
80-76	Very good functional status
75-71	Good functional status
70-66	Fair functional status
65-61	Poor functional status
60 or less	Very poor functional status

A score of 80-76 indicates that the patient has a very good functional status and can perform most activities of daily living (ADLs) without difficulty. A score of 75-71 indicates that the patient has good functional status and can perform most ADLs without assistance, but may have some difficulty with more strenuous activities. A score of 70-66 indicates that the patient has fair functional status and can perform most ADLs, but may need some assistance with more difficult tasks. A score of 65-61 indicates that the patient has poor functional status and may need assistance with many ADLs. A score of 60 or less indicates that the patient has a very poor functional status and may need assistance with most ADLs.

It is important to keep in mind that these are just general guidelines, and the interpretation of an LEFS score may vary depending on the individual’s age, gender, and overall health status. For example, an older adult may be considered to have good functional status with a score of 70, while a younger adult may be considered to have fair functional status with the same score.

Here are some additional factors to consider when interpreting LEFS scores:

• The patient’s self-report: The LEFS is a self-report measure, which means that it is based on the patient’s own perception of their functional status. This can be affected by a number of factors, such as pain, muscle fatigue, and motivation.
• The patient’s baseline functional status: The LEFS is not a standardized measure, so it is important to consider the patient’s baseline functional status before interpreting their score. A patient who starts with poor functional status may have a more difficult time improving their score, even if they make significant progress.
• The patient’s goals: The interpretation of a LEFS score will also depend on the patient’s goals. For example, a patient who is trying to return to work may need a higher score than a patient who is trying to maintain their independence at home.

Overall, LEFS scores are a valuable tool for assessing lower extremity function and tracking progress over time. However, it is important to interpret scores with caution and to consider all of the factors that may affect a patient’s functional status.
