The LEFS is intended for use on adults with lower extremity conditions.[1]
Method of Use[edit | edit source]
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 activities.[1] 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.
