Reliability and Validity of the Finnish Visual Analogue Scale Foot and Ankle and the Lower Extremity Functional Scale

Study Overview
=================
Brief Summary
-----------------
There are no validated patient-reported outcome measures to assess lower extremity function in Finnish language. The present study aimed to 1)translate and culturally validate the Finnish versions of the Visual Analogue Scale Foot and Ankle and the Lower Extremity Functional Scale, and 2) study the psychometric properties of these two questionnaires

Detailed Description
-----------------
This study assesses the reliability and validity of the Finnish versions of the Visual Analogue Scale Foot and Ankle and the Lower Extremity Functional Scale. The English versions were translated and trans-culturally adapted into Finnish language according to well accepted international translation guidelines. The psychometric properties are assessed by internal validity, intraclass correlation coefficient and test-retest reliability.
