LEFS QUESTIONNAIRE PDF

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.

Sensitivity to change was examined using a prognosis rating. 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.

Thank you for submitting a comment on this article. Two instruments to evaluate the functional status of elderly patients with OA were employed: Several methods have been used by us and by other researchers in an attempt to questionniare among patients’ levels of change, including other clinical measures eg, spinal flexion29 retrospective global rating of change, 272937 — 41 the achievement of treatment goals, 35 and an external prognostic rating of change.

An example of questionaire application of the LEFS to establish functional level, set goals, and track progress and outcome.

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

Comparison of the WOMAC Western Ontario and McMaster Universities osteoarthritis index and a self-report format of the selfadministered Lequesne-algofunctional index in patients with knee and hip osteoarthritis. 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.

You must accept the terms and conditions. The LEFS is a self-report questionnaire.

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

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. 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. When refering to evidence in academic writing, you should always try to reference the primary original source.

The ISCD’s official positions updated The selection of the SF was based on the literature documenting the measurement properties of the SF, including its applicability to patients with lower-extremity dysfunction.

Our goal was to develop a self-report condition-specific measure that would yield reliable and valid measurements and that would be appropriate for use as a clinical and research questionanire. 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.

Any of your usual work, housework, or school activities. Sitting for 1 hour. Clinicians were asked to identify the questionnairr amount of change on the LEFS, in scale points, that would suggest that improvement had occurred. The interrater reliability for the prognostic ratings was determined using a type 3,2 intraclass correlation coefficient ICC.

Ware JE Jr, Kosinski. The Italian version of the lower extremity functional scale was reliable, valid, and responsive.

The median score for the LEFS for the whole population was 77 out of a maximum of The SF has served as the principal generic measure for comparisons with condition-specific measures. Methodological problems in the retrospective computation of responsiveness to change: Comparison of methods for the scoring and statistical analysis of SF health profile and summary measures: Pearson correlations and one-way analyses of variance were used to examine construct validity.

As a result of the item analysis, 2 items were removed from the original LEFS and 1 item was reworded. Several barriers to the widespread adoption of generic and condition-specific 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.

Reliability of the LEFS scores was also quantified using the standard error of measurement SEMa representation of measurement error expressed in the same units as the original measurement, in this case, LEFS points. Individual-patient monitoring in clinical practice: The LEFS was conceived as a measure applicable to a broad spectrum of lower-extremity problems. The maximum possible score is 80 points, indicating very high function. Accordingly, it was necessary that the first study compare the LEFS with a measure of established validity.

The LEFS appears to overcome, to some extent, the barriers identified for questionjaire of a health status measure in clinical practice. 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.

No additional items were identified as important to include in the LEFS by these additional processes.
