Lower Extremity Functional Scale

The Lower Extremity Functional Scale (LEFS) is a patient-reported questionnaire used to evaluate functional impairment of the lower extremities. It consists of 16 questions asking patients to rate their ability to perform various physical activities on a scale of 0 to 4, with higher scores indicating better function. The total possible score is 80. The LEFS was developed by researchers at McMaster University to monitor patients over time and evaluate the effectiveness of interventions for lower extremity disorders.
