Lower Extremity Functional Scale

Healthcare professionals use LEFS to measure how well someone can do activities related to their lower body. It assesses an individual's ability to perform tasks such as walking, climbing stairs, and squatting.

The LEFS scores range from 0 to 4. To score LEFS, you must add the total number of points rated by the patient for each activity. A lower score indicates greater disability, while a higher score suggests better functional ability.

The LEFS should be completed regularly every six weeks or before and after physical therapy interventions.
