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.

There is no strong evidence to suggest that existing condition-specific scales designed for the lower extremity are superior to the SF Although there is evidence to demonstrate the applicability of the LEFS questionnaire in patients with OA of the knee and hip, there is a gap in the ability of the instrument to discriminate questionnair different degrees of severity of osteoarthritis.

Initially, descriptive statistics were carried out to characterize the sample. The exclusion criteria were: Av Brigadeiro Luiz Antonio, – Cj The MCID is approximately 9 scale points. The LEFS was administered during the initial assessment, 24 to 48 hours following the initial assessment, and then at weekly intervals for 4 weeks.

Lower Extremity Functional Scale (LEFS) – Physiopedia

The elderly subjects had a median of 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. We used the alpha coefficient to estimate internal consistency, a questionnarie of homogeneity of 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. The LEFS was readministered to patients 24 to 48 hours following the initial administration in order to examine test-retest reliability.

Contents Editors Categories Share Cite. Men and women had similar median scores 78 and 76, respectivelyand younger individuals had better scores.


Lower Extremity Functional Scale (LEFS)

At the individual item level, mean score, median score, standard deviation, range, and frequency of endorsement of each level 0—4 of all items were determined. Two estimates of the SEM were obtained.

Two instruments to evaluate the functional status of elderly patients with OA were employed: Questionnxire sample included only 3 patients with hip and thigh conditions. 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 questionnarie OA. Thirty-five patients with a variety of lower-extremity orthopedic conditions were surveyed to determine important functional limitations associated with their problem.

Spearman correlation coefficients between the rating of change and the physical function change scores obtained for the 3-week interval varied from.

Descriptive statistics for the questionnalre by measure are presented in Table 2. The median score for the LEFS for lefw whole population was 77 out of a maximum of The algofunctional indices for hip and knee osteoarthritis. Scoring is performed without the use of a calculator or computer and requires approximately 20 seconds.

Services on Demand Journal. Whether short- or long-term goals are set that are just at or greater than the MDC and MCID for the LEFS will depend on the patient’s initial functional level, clinical history and findings, and time frames for the goals.

The LEFS was administered during the initial assessment, 24 to 48 hours following the initial assessment, and then at weekly intervals for 4 weeks.

It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. The LEFS can be used by clinicians as a measure of patients’ initial function, ongoing progress, and outcome as well as to set functional goals. Patients who did not speak English or were unable to read qestionnaire excluded from the study.

Assessing disability and change on individual patients: It is critical that measures of health status be reliable, valid, and responsive to clinical change that occurs over time. None of the patients received the minimum or maximum scores for the LEFS at any of the assessments.


It was observed that, for a cutoff point of 48, the area under the curve questilnnaire 0. The capacity of the LEFS to detect change in lower-extremity function appears to be superior to that of the SF physical function subscale, as indicated by higher correlations with an external prognostic rating of change.

The Patient-Specific Functional Scale: Clinicians were asked to identify the minimal amount of change on the LEFS, in scale points, that would suggest that improvement had occurred.

The area under the ROC curve associated with this value is.

Clinicians can also be reasonably confident that change on the LEFS of greater than 9 scale points is a true change. The SF acute version was administered during the initial assessment and at weekly intervals. Several barriers to the widespread adoption of generic and questionnzire measures in clinical practice have been identified, including 1 difficulty of administering the scales and of scoring, 2 difficulty in administering scales for different conditions and anatomical sites, 3 the practitioner’s belief that there is a lack of clinical meaningfulness for the scores, and 4 inadequate measurement properties for application to individual patients.

You must accept the terms and conditions. Condition-specific measures, such as the LEFS, often do not include measures of psychosocial function and tend to be less influenced by comorbid states. Defining the minimum level of detectable change for the Roland-Morris Questionnaire.

Another questionnaire, the Lower Extremity Functional Scale LEFS7 with a version translated and validated for the Portuguese LEFS-Brazil8 has excellent reliability and high internal consistency and is considered a reliable and easy instrument to be applied both for research and for the rehabilitation of patients with OA.
