Adult visitors to the outpatient clinic of the Department of Surgery and also staff at 4 different Dutch hospitals were asked to participate in this study.

There was no statistically significant correlation between socioeconomic status and LEFS score, but people who were unfit for work had a significantly worse LEFS score. 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: Performing light activities around your home.

Qual Life Res ; 4 4: The average of the 5 clinician estimates for MCID was 10 scale points, suggesting that the statistical approach has resulted in a reasonable estimate of the MCID.

Find articles by Niels W L Schep. As expected, the LEFS score showed a negative correlation with age; i. All analyses were performed using SPSS version When refering to evidence in academic writing, you should always try to reference the primary original source. The results of the studies suggest that a correlation coefficient of approximately.

Evaluating changes in health status: 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.


Your comment will be reviewed and published at the journal’s discretion. For the LEFS, however, no such data are available. 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.

Clinical outcome scoring of intra-articular calcaneal fractures. Abstract Background and Purpose. Sensitivity to change was examined using a prognosis rating. Health state utilities in knee replacement surgery: The same question was posed to clinicians in terms of deterioration.

The LEFS is intended for use on adults with lower extremity conditions. The capacity of the LEFS and the SF 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. Normative values in the general population in Norway.

Evaluation of knee ligament surgery results with special emphasis on use of a scoring scale. Responsiveness of functional status in low back pain: This suggests that function may be independent of SES in a normal population, but in posttraumatic patients SES may negatively influence treatment outcome. Running on even ground. Because the LEFS measures physical function but not overall health, we believe that a generic health status measure such as the SF should be used to supplement the LEFS when the goal is to measure the overall health status of our patients.

View large Download slide. Data were collected over a 4-month period. In our study, we also used a rating of expected change as the theory for change.

Assessing scal responsiveness of functional scales to clinical change: There is no strong evidence to suggest that existing condition-specific scales designed for the lower extremity are superior to the SF Design of the paper: 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.


Pearson correlations and one-way analyses of variance were used to examine construct validity. The correlations relating scwle change scores are presented in Table 5.

The physical and mental component summary scores represent weighted composite scores derived from the 8 health concept scales. Methodological problems in the retrospective computation of responsiveness to change: Since it was not possible to perform a prospective sample size calculation, we chose to include a minimum of individuals at each hospital.

Lower Extremity Functional Scale (LEFS)

Only prospective research, however, validates the use of this measure in clinical decision making. The area under the ROC curve associated with this value is.

Component summary scores are scaled to have a mean of 50 and a standard deviation of 10 in the general population of the United States. The magnitudes of the correlations between the prognostic ratings and the LEFS, SF physical function subscale, and SF physical component summary scores were formally compared using the method of Williams 48 for dependent data. This means that it is unknown what normal scores for a healthy individual should be.

Are available health status surveys adequate.
