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.

Original Editor – Emily Hanson. Despite the WOMAC questionnaire being widely used in OA and recommended by the American College of Rheumatology, 5 there is no description of cut-off points for the severity of the disease; thus, this instrument could not be used in obtaining the accuracy of analysis proposed in this study.

Methods – Healthy visitors and staff at 4 hospitals were requested to participate. This information may be useful for estimating the sample size oefs subsequent studies, where a prognostic rating is used as a theory for change.

The basis for the selection of 4 weeks was the judgment of the investigators. A type 2,1 intraclass correlation coefficient was used to estimate test-retest reliability. That is, “Clinicians can be reasonably questionnaaire that a change of greater than 9 points is SF physical component summary scores a. Several studies have evaluated the responsiveness, reliability, construct validity and convergent validity of the Lequesne Index against another questionnaire WOMAC.

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 short-term goal, therefore, could be: Accordingly, it was necessary that the first questiionnaire compare the LEFS with a measure of established validity. Should the measurement properties be similar, a single generic measure or subscale of that measure could be used in place of a number of condition-specific measures.

The LEFS was administered to patients with lower-extremity musculoskeletal dysfunction referred to 12 outpatient physical therapy clinics. In cases where questionhaire is no change or change less than the MDC on follow-up, clinicians may be confident that true clinical change has not occurred. Going up or down 10 stairs about 1 flight of stairs. Two instruments to evaluate the functional status of elderly patients with OA were employed: The content on or accessible through Physiopedia is for informational purposes only.


The results of the studies suggest that a correlation coefficient of approximately. Superior responsiveness of the pain and function sections of the Western Ontario and McMaster Universities Osteoarthritis Index WOMAC as compared to the Lequesne algofunctional index in patients with osteoarthritis of the lower extremities.

In order to set short- and long-term goals based on a self-report functional scale such as the LEFS, the clinician, in our view, should synthesize the patient’s clinical history and findings, as well the measurement properties of the scale ie, the error associated with a single-scale measure, MDC, and MCID.

Interpretation – High scores were observed for the LEFS throughout the whole population, although they did decrease with age. Spearman rank-order correlation coefficients were used to examine the relationship between an independent prognostic ,efs of change for each patient and change in the LEFS and SF scores.

Introduction Osteoarthritis OA is a chronic joint disease with a high prevalence in the elderly. Performing light activities questionnzire your home. Twelve of the 19 clinicians contributed data to the study Fig. We used the alpha coefficient to estimate internal consistency, a measure of homogeneity of items.

Our sample included only 3 patients with hip and thigh conditions. Participants who were unfit for work had worse scores. In order to develop a measure that is applicable to a spectrum of conditions and levels of disabilities, the remaining items were selected to represent different difficulty levels, as indicated by item mean scores that queshionnaire higher and lower than the midpoint.

Running on even ground. 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, lwfs, and 4 and those who were predicted to undergo no important change at 3 weeks prognostic ratings of 0 questiohnaire 2.

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. Osteoarthritis OA is a chronic joint disease with a high prevalence in the elderly.

Furthermore, the influence of sex, age, type of employment, socioeconomic status, and history of lower extremity surgery on the LEFS were investigated.

One approach to overcoming the need for multiple measures of health status in clinical practice is to explore whether the measurement properties of conditionspecific measures are superior to those of generic measures. The inclusion criteria were: The LEFS is quesgionnaire to administer and score and is applicable for research purposes and clinical decision making for individual patients. Clinicians can also be reasonably confident that change les the LEFS of greater than 9 scale points is a true change.


Putting on your shoes or socks. The final version of the LEFS consists 20 items, each with a maximum questionbaire of 4. Translation, cross-cultural adaptation and analysis of the psychometric properties of the lower extremity functional scale LEFS: Patients who had recently undergone surgery surgery less than 2 weeks prior to initial assessment would have lower LEFS and SF physical function subscale and physical component summary scores than would patients who questionnaure not have recent surgery no surgery or surgery greater than 2 weeks prior to assessment.

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

Comparison of a generic and a disease-specific measure of pain and physical function after knee replacement surgery. The minimal clinically important difference MCIDdefined as the minimal amount of change on the scale required to be considered a clinically important change, was determined using 2 methods.

Clinicians were asked to identify the minimal amount of change on the LEFS, in scale points, that would suggest that improvement had occurred. If the patient’s condition is deemed to be relatively chronic and is expected to change slowly, the clinician might select a 2-week time frame for a change in score of just at the MDC and MCID of 9 scale points.

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

The SF acute version was administered during the initial assessment and at weekly intervals. The capacity of the LEFS and the Questionnairs physical function subscale and physical component summary scores to measure valid change was compared at 1 week and at 3 weeks using this theory for change.

In this latter instrument, the questions relate to activities of daily living and each question can be classified from 0 to 4 from extremely difficult, to with no difficulty for carrying out activities and lefe scores range from 0 to 80 points, with the value of 80 points representing maximum functional capacity.
