Description
Objective
The objective of the Lower Extremity Functional Scale (LEFS) is to measure “patients’ initial function, ongoing progress, and outcome” for a wide range of lower-extremity conditions.[1][2]
Intended Population
The LEFS is intended for use on adults with lower extremity conditions.[1][2]
Method of Use
The LEFS is a self-report questionnaire. Patients answer the question “Today, do you or would you have any difficulty at all with:” in regards to twenty different everyday activities.[1][2]
Patients select an answer from the following scale for each activity listed:
- Extreme Difficulty or Unable to Perform Activity
- Quite a Bit of Difficulty
- Moderate Difficulty
- A Little Bit of Difficulty
- No Difficulty
The patient’s score is tallied at the bottom of the page. The maximum possible score is 80 points, indicating very high function. The minimum possible score is 0 points, indicating very low function.
