Patients’ characteristics are shown in Table 1. Methods Healthy visitors and staff at 4 hospitals were requested to participate. Each subscale score can vary from 0 towith higher scores representing more desirable health states. None of the patients in our study scored at 0 or leds 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 sccale this type of patient population.

Ware JE Jr, Kosinski. The questionnaire was filled out by 1, individuals. High scores were observed for the LEFS throughout the whole population, although it did decrease with age. 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. 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 tool.

Healthy visitors and staff at 4 hospitals were requested to participate. The conceptual framework that guided the development of the LEFS included that the scale 1 be based on the World Health Organization’s model of disability and handicap, 43 2 be efficient to administer, score, and record in the medical record with respect to patient and clinician time, 3 be applicable to a wide variety of patients with lower-extremity orthopedic conditions, including patients with a range of disability levels, conditions, diseases, treatments, and ages, 4 be applicable for documenting function on an individual patient basis as well as in groups, such as for clinical outcomes assessment and clinical research purposes, 5 be developed using a systematic process of item selection and item scaling, 2 6 yield reliable measurements have internal consistency and test-retest reliabilityand 7 yield valid measurements at a single point in time and sensitive to valid change.


To date, the responsiveness of several of the SF subscales and the physical component summary score have been shown to be superior or equivalent to condition-specific scales relevant to the lower extremity.

For other subpopulations e. No additional items were identified as important to include in the LEFS by these additional processes. A type 2,1 intraclass correlation coefficient was used to estimate test-retest reliability.

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. Going up or down 10 stairs about 1 flight of stairs.

The World Health Organization’s model of disability 43 served as the basis for the item generation phase of the scale development. View large Download slide. In this case, depending on the clinical picture and time frame since the previous assessment, a change in lets, referral, or discharge of the patient may be kefs. J Hand Surg Eur Vol ; sacle 2: Drafting of the work: Interpretation High scores were observed for the LEFS throughout the whole population, although they did decrease with age.

Normative data for PROMs can aid in this problem by acting as reference data for a healthy population.

Normative data for the lower extremity functional scale (LEFS)

Individuals were excluded if they had had lower extremity surgery within 1 year of filling out the questionnaire. HAND ; 9 1: Reproducibility and responsiveness of health status measures: National Center for Biotechnology InformationU. The lower extremity functional scale LEFS is a scal and validated instrument for measurement of lower extremity function.

Normative data for the lower extremity functional scale (LEFS)

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. Putting on your shoes or socks.

In addition, scle the LEFS was designed for use in individuals leefs lower extremity conditions, the fact that a ceiling effect was found for healthy individuals is notable, but it should not limit the validity of the test in the population that it was designed for.


Application to Individual Patients. Clinicians were asked to estimate the amount of change that they would consider to be clinically important for initial LEFS scores of 10, 25, 40, 55, and Methods for assessing condition-specific and generic functional status outcomes after total knee replacement.

Eur J Orthop Surg Traumatol ; 24 7: Author information Article notes Copyright and License information Disclaimer. Osteoporos Int ; 27 2: Three orthopedic physical therapists, each with at least 10 years of experience in orthopedic physical therapy practice, reviewed the 22 items and were given the opportunity to add additional items. Furthermore, the influence of sex, age, type of employment, socioeconomic status, and history of lower extremity surgery on the LEFS were investigated.

Running on even ground. A history of lower extremity surgery was associated with a lower LEFS score. The short-term goal, therefore, could be: Results 1, individuals fulfilled the inclusion criteria and were included in the study.

The LEFS is intended for use on adults with lower extremity conditions. Men had a statistically significant better score than women.

Methodological problems in the retrospective computation of responsiveness to change: J Pak Sccale Assoc ; 10 oct; lefx We used the alpha coefficient to estimate internal consistency, a measure of homogeneity of items. The lower extremity functional scale LEFS is a well-known and validated patient-rated outcome measure PROM that can be used to measure lower extremity function.

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.

There are 2 major limitations to this study. The LEFS was administered to patients with lower-extremity musculoskeletal dysfunction referred to 12 outpatient physical therapy clinics.
