JoJozragore Results — 1, individuals fulfilled the inclusion criteria and were included in the study. The initial version of the scale consisted of 22 items. Interpretation — High scores were observed for the LEFS throughout the whole population, although they did decrease with age. This information may be useful for estimating the sample size for subsequent studies, where a prognostic rating is used as a theory for change. Please check for further notifications by email. 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.

Making sharp turns while running fast; Hopping; Rolling over in bed. As per the original study, the main objective of LEFS is to measure patient initial function, rate ongoing progress and quantify outcome. The range of lower limbs conditions the self report questionnaire addresses includes musculoskeletal disorders, hip, knee or ankle pain as well as foot injuries.
In terms of internal reliability the LEFS rates at 0. The results have shown that the change detection in the lower-extremity function in LEFS has greater degrees of correlation with external prognosis compared to the physical function subscale of SF Since the lower back area and the lower extremities are anatomically and functionally related and a common symptom of patients with LBP is radiating low pain, LEFS has been used, with satisfactory psychometric results as supplementary measure of functional limitation.
The clinimetric properties of this lower extremity scale have been tested in a population of patients with ankle fracture. While for medium and long term follow up the scale was found to lack certain specificity, the responsiveness and internal consistency for short term follow up were rated high. LEFS score interpretation The maximum score obtainable is 80 points which signifies complete function and the lowest score is 0 which indicates very low function.
All LEFS scores are then awarded as number of points out of the total of The lower the score, the higher the degree of impairment caused by the lower extremity problem. The minimal detectable change is 9 scale points meaning that for improvement or degradation to be valid, the difference between two subsequent scores needs to be equal to or higher than 9.
