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.

The selected subjects were informed about the objectives of the study and signed a Consent form, agreeing in participating in the study. The LEFS is a self-report questionnaire. Sensitivity to change was examined using a prognosis rating. In this case, the goal may be: Measures exist for people with general conditions of the knee, 5 patellofemoral joint disorders, 67 ligamentous deficiency, 8 — 10 and joint replacement.

The SF acute version was administered during the initial assessment and at weekly intervals.

The reliability, validity, and responsiveness of measurements obtained with the SF have been documented in diverse patient groups. Of these, 36 The total possible score of 80 indicates a high functional level Appendix.

The ISCD’s official positions updated The corrected item-item total correlation is an estimate of the degree to which a single item score correlates with the total scale score with that item removed. Two estimates of the SEM were obtained.

Lower Extremity Functional Scale (LEFS)

A total of patients were questionnsire into the study. This categorization could facilitate the classification of functional impairment of these individuals, providing additional criteria to check the impact of the therapeutic approaches in activities of daily living of elderly patients with OA.

Radiological assessment of osteo-arthrosis. Toggle navigation p Physiopedia. Lower Extremity Functional Scale. In light of this finding as well as the greater ease of administering and scoring the LEFS, this scale appears to be a good choice for documenting lower-extremity function.

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

One-way analyses of variance were used to examine the hypotheses about validity that specified that there would be a difference in initial LEFS scores and SF physical function subscale and physical component summary scores between: Spearman rank-order correlation coefficients were used to examine the relationship between an independent prognostic rating of change for each patient and change in the LEFS and SF scores.


Items were generated for the LEFS by a process of reviewing existing questionnaires as well as surveying clinicians and patients.

However, LEFS may represent a promising alternative compared to the WOMAC, because it has good internal consistency and is able to discriminate issues such as pain and function as supported by the findings by Pua et al.

Our sample included only 3 patients with hip and thigh conditions. The short-term goal, therefore, could be: The SF has served as the questionanire generic measure for comparisons with condition-specific measures. Our results, coupled with those of Westaway et al, 45 provide support for using a prognostic rating of change as a theory for evaluating a measure’s sensitivity to change.

Getting into or out of the bath. The physical and mental component summary scores represent weighted composite scores derived from the 8 health concept scales. The LEFS is easy to administer and score and is applicable to a wide range of disability levels and conditions and all lower-extremity sites. This class of ICC is appropriate when ratings questionniare averaged and an adjustment has been applied to address a systematic difference between raters.

Men and women had similar median scores 78 and 76, respectivelyand younger individuals had better scores. Sign In or Create an Account. Comparison of a generic and a disease-specific measure of pain and physical function after knee replacement surgery.

The interrater reliability for the prognostic ratings was determined using a type 3,2 intraclass correlation coefficient ICC.

The LEFS was administered during the initial assessment, 24 to 48 hours quesfionnaire the initial assessment, and then at weekly intervals for 4 weeks. Close mobile search navigation Article navigation.

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. A item short-form health survey: Making sharp turns while running fast. Health state utilities in knee replacement surgery: Twelve of the 19 clinicians contributed data to the study Fig.


There is no strong evidence to suggest that existing condition-specific scales designed for the lower extremity are superior to the SF Three orthopedic physical therapists, each with at least 10 years of experience in orthopedic physical therapy practice, reviewed the 22 items and were given the opportunity to add additional items.

However, the definition of cut-off points in its scale of severity of OA have not been previously published, and these findings could have a clinical relevance, both for evaluation and for analysis of the effectiveness of interventions in this patient group. A type 2,1 intraclass correlation coefficient was used to estimate test-retest reliability.

Two orthopedic physical therapists who were blind to the patient’s functional scale scores performed independent prognostic ratings on each patient, which were subsequently averaged. Clinicians’ judgments of MCID were compared with the statistical approach. In this latter instrument, the questions relate to activities of daily living qusetionnaire each question can be classified from 0 to 4 from extremely difficult, to with no difficulty for carrying out activities and its scores range from 0 to 80 points, with the value of 80 points representing maximum functional capacity.

A specialist was responsible for the classification of these subjects in categories relating to the radiographic findings ; this professional was blinded to the analyzed outcomes. No additional items were identified as important to include in the LEFS by these additional processes. The broad categories of orthopedic conditions in this group were: The LEFS was readministered to patients 24 to 48 hours following the initial administration questionnarie order to examine test-retest reliability.

Rather than asking whether the LEFS is superior to existing measures, future research should inquire about the equivalence of the LEFS and the competing measures of interest. That is, a change of more than 9 points represents a true change in the patient’s condition. Performing light activities around your home. Lesf basis for the selection of 4 weeks was the judgment of the investigators.
