Background and Purpose. Subjects and Methods. The LEFS was administered to patients with lower-extremity musculoskeletal dysfunction referred to 12 outpatient physical therapy clinics. The LEFS was administered during the initial assessment, 24 to 48 hours following the initial assessment, and then at weekly intervals for 4 weeks.

Normative Data ACL Reconstruction: Alcock et al, LEFS scores can be used to predict functional recovery after surgery with rapid improvements 7 to 8 weeks post with slower improvements after.
Improvement adheres to bone and soft tissue healing as well as a regain of muscle inhibition secondary to decreased swelling and pain. An example of such a prediction would be at 16 weeks where the predicted LEFS score is 63 out of It is speculated that further treatment could overcome any remaining deficits. High construct validity of the Lower Extremity Functional Scale was demonstrated using Rasch analysis. At all time points, the scale explained a high variance in activity limitation.
Responsiveness in the medium term warrants further validation. First postoperative to second postoperative interval: 1. Construct Validity Hip Osteoarthritis: Pua et al, Pearson coefficients and one way analysis of variance, compared with SF, showed to be more sensitive to change.

Normative data for the lower extremity functional scale (LEFS)

Lower Extremity Functional Scale
Assessment Tool Category: Physical Functioning. Setting: Clinical Setting Rehabilitation. Method of Delivery: Health professional and self administered questionnaire. Description: The Lower Extremity Functional Scale LEFS was developed to provide health care professionals with an efficient tool to measure the functional ability of patients with lower extremity issues. The test then consists of 20 items.
The lower extremity functional scale LEFS is a well-known and validated instrument for measurement of lower extremity function. The LEFS was developed in a group of patients with various musculoskeletal disorders, and no reference data for the healthy population are available. Here we provide normative data for the LEFS. Healthy visitors and staff at 4 hospitals were requested to participate. A minimum of volunteers had to be included at each hospital. Participants were excluded if they had undergone lower extremity surgery within 1 year of filling out the questionnaire, or were scheduled for lower extremity surgery.
