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. No difficulty: with usual work, housework or school activities; with usual hobbies, recreational or sporting activities; getting into or out of the bath; walking. Another questionnaire, the Lower Extremity Functional Scale (LEFS), with a version translated and validated for the Portuguese (LEFS-Brazil), has excellent.

Normative data for the lower extremity functional scale (LEFS).

Measurement properties of the RM A total of patients were entered into the study. Rolling over in bed. Constitution of the World Health Organization. The American College of Rheumatology criteria for the classification and reporting of osteoarthritis of the hip.

Retrieved from ” https: Please check for further notifications by email. This information may be useful for estimating the sample size for subsequent studies, where a prognostic rating is used as a theory for change.

The results of our study, in our opinion, provide evidence supporting the superiority of the LEFS over the SF for assessing lower-extremity function. In the first approach, we used the prognostic ratings of change to separate patients into those who were predicted to undergo important change prognostic ratings of 2, 3, and 4 and those who were predicted to undergo no important change at 3 weeks prognostic ratings of 0 and 2.

Generic measures, such as the SF, are not generally practical for application at an individual patient level due to the length of the scale and complexity of scoring.

The total possible score of 80 indicates a high functional level Appendix. Email alerts New issue alert. Prognostic ratings were based on documentation review of patients’ diagnoses, age, chronicity, number of comorbid conditions, and type of surgery and time since surgery, where applicable. Men and women had similar median scores 78 and 76, respectivelyand younger individuals had better scores.


Introduction Osteoarthritis OA is a chronic joint disease with a high prevalence in the elderly. We believe that there is a need for a functional measure that is easy to administer and score and applicable to a wide range of patients with lower-extremity orthopedic conditions. That is, a change of more than 9 points represents a true change in the patient’s condition. To date, the responsiveness of several of the SF subscales and the physical component summary score have been shown to be superior or equivalent to condition-specific scales relevant to the lower extremity.

Close mobile search navigation Article navigation. One or more theories are developed, and the extent to which a measure yields results concordant with the theory provides support for the validity of the measure. The inclusion criteria were: Your comment will be reviewed and published at the journal’s discretion. Clinicians can also be reasonably confident that change on the LEFS of greater than 9 scale points is a true change.

The broad categories of orthopedic conditions in this group were: Subjects were consecutive patients referred for physical therapy with any lower-extremity musculoskeletal condition defined as any condition of the joints, muscles, or other soft tissues of the lower extremity. The SF acute version was administered during the initial assessment and at weekly intervals.

This approach was based on clinical judgment and previous work by Westaway et al, 45 whose data suggested that experienced clinicians can make prognoses about patients. Patients with acute conditions would demonstrate lower LEFS scores and SF physical function subscale and physical component summary scores than would patients with chronic conditions. We surveyed existing questionnaires. The LEFS was administered to patients with lower-extremity musculoskeletal dysfunction referred to 12 outpatient physical therapy clinics.

Patients were placed in one of the following categories based on a review of documentation, which included diagnosis and the time since onset of condition or the time since surgery or cast removal: The short-term goal, therefore, could be: In a previous study, 24 we observed that the LEFS questionnaire shows a strong correlation with the Lequesne Index and also with WOMAC, confirming its validity as a clinical tool for the analysis of functional impairment in elderly patients with OA.


Descriptive statistics for the patients by measure are presented in Table 2.

The LEFS is a self-report questionnaire. Ware JE Jr, Kosinski. Men had a slightly higher score than women. Your usual hobbies, questionnaird or sporting activities.

The SF acute version was administered during the initial assessment and at weekly intervals. The objective of the Lower Extremity Functional Scale LEFS is to measure “patients’ initial function, ongoing progress, and outcome” for a wide range of lower-extremity conditions.

The same question was posed to clinicians in terms of deterioration. Lower Extremity Functional Scale. As a result of the item analysis, 2 items were removed from the original LEFS and 1 item was reworded.

Normative data for the lower extremity functional scale (LEFS).

Subsequently, only individuals diagnosed with OA underwent radiographic examinations of the hips and knees in the supine position, with frontal and side views, based on the criteria of Kellgren and Lawrence 18 ; all individuals who were submitted to the study were with grade II mild OA to IV advanced OA.

The basis for the selection of 4 weeks was the judgment of the investigators. Condition-specific measures, such as the LEFS, often do not include measures of psychosocial function and tend to be less influenced by comorbid states.

The final version of the LEFS consists 20 items, each with a maximum score of 4.
