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.

Lower Extremity Functional Scale (LEFS) – Physiopedia
Clinicians can be reasonably confident that a change of greater than 9 scale points is not only a true change but is also a clinically meaningful functional change.
A description of the patients is presented in Table 1.
The basis for the selection of 4 weeks was the judgment of the investigators. A minimum of volunteers had to be included at each hospital.
To obtain this estimate, the SEM is multiplied by the z value for the confidence level of interest, and this quantity is multiplied by the square root of 2.
Assessing disability and change on individual patients: 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. Constitution of the World Health Organization.
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.
In addition, the SF auestionnaire version was administered during the initial assessment and at the weekly follow-up assessments.
Thank you for submitting a comment on this article. Running on uneven ground. We surveyed existing questionnaires.

Clinicians can also be reasonably confident that change on the Llefs of greater than 9 scale points is a true change. The algofunctional indices for hip and knee osteoarthritis. There was a questionnare correlation between the prognostic rating of change and the LEFS than between the prognostic rating of change and the SF physical function score. 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.
Another questionnaire, the Lower Extremity Functional Scale LEFSquestiohnaire 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.
None of the patients in our study scored at 0 or 80 on the scale at admission or at the 3-week follow-up assessment, indicating that there is no ceiling or floor effect associated with the LEFS in this type of patient population.
Each of the component summary scores is scaled to have a mean of 50 and a standard deviation of 10 for the general population of the United States. How to cite this article. The factor loadings varied from.
The SF acute version was administered during the initial assessment and at weekly intervals. In addition, local institutional review board approval was obtained by clinicians and clinics participating in the study, where necessary.
Spearman rank-order correlation levs were used to examine the relationship between an independent prognostic rating of change for each patient and change in the LEFS and SF scores. The purpose of this article is to report on the development and initial validation of a newly developed condition-specific measure, the Lower Extremity Functional Scale LEFSincluding the determination of internal consistency, reliability, construct validity, sensitivity to change, and clinical application.
Normative data for the lower extremity functional scale (LEFS).
The SF has been used to assess outcomes in people with hip, knee, and ankle dysfunction. Health state utilities in knee replacement surgery: The SF has served as the principal generic measure for comparisons with condition-specific measures. The correlations relating to change scores are presented in Table 5. The second approach was questioonnaire survey of 5 clinicians who reported that they had used the LEFS for an minimum of 4 months and on at least 10 patients as a clinical decision-making tool.
Only prospective research, however, validates the use of this measure in clinical decision making.
Lower Extremity Functional Scale (LEFS)
Informed questionnxire was obtained from all patients. The results of our study, in our opinion, provide evidence supporting the superiority of the LEFS over the SF for assessing lower-extremity function. Spearman rank-order correlation coefficients were used to examine the questionnzire between the prognostic rating and change in the following functional status scores at 1 week and 3 weeks: It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide.
