Understanding the Structure of the LEFS PDF
Overview of the Content
The LEFS outcome measure PDF typically includes:
- Instructions for administration
- The questionnaire itself
- Scoring guidelines
- Interpretation of results
- Additional resources or references
The LEFS Questionnaire
The core of the PDF is the questionnaire, which comprises 20 items. Each item assesses a different aspect of lower limb function, such as walking, running, or stair climbing.
Sample items include:
- Walking more than 2 blocks
- Running on level ground
- Kneeling or squatting
- Getting in and out of a car
Response Scale
Participants rate their difficulty in performing each activity over the past week using a 5-point Likert scale:
- 0 = Extreme difficulty or unable to perform
- 1 = Quite a bit difficult
- 2 = Moderately difficult
- 3 = Slightly difficult
- 4 = No difficulty
Scoring and Interpretation
Once completed, the total score is calculated by summing individual item scores, providing a score range from 0 to 80. Higher scores indicate better function.
Interpreting the scores involves:
- Recognizing minimal clinically important difference (MCID)
- Comparing scores over time to assess progress
- Using normative data for context
