Lower Extremity Functional Scale References LEFS has been translated and adapted in different populations like, Italian, Canadian French, Dutch, Arabic, Brazilian Portugese, Malaysian, Finnish, Persian, Turkish, Taiwan, Chinese and Dutch translated and adapted version are also tested for validity and reliability. That is, the tabulated score is within 5 points of a patient's 'true' score. The LEFS has good measurement properties-namely test-retest reliability and cross-sectional construct validity-and it could be an alternative to WOMAC-PF. The capacity of the LEFS to detect change in lower-extremity function appears to be superior to that of the SF-36 physical function subscale, as indicated by higher correlations with an external prognostic rating of change. a clinically meaningful functional change.' That is, 'Clinicians can be reasonably confident that a change of greater than 9 points is. The minimum clinically important difference (MCID) for the LEFS is 9 points.

That is, a change of more than 9 points represents a true change in the patient's condition. The minimum detectable change (MDC) for the LEFS is 9 points. The LEFS is a valid tool as compared to the SF-36.

Test-retest reliability estimates were R=.86 (95% lower limit CI=.80) for the entire sample (n=98) and R=.94 (95% lower limit CI=.89) for the subset of patients with more chronic conditions (n=31). Internal reliability for the LEFS is excellent (α=0.96).
