Responsiveness and validity of two outcome measures of instrumental activities of daily living in stroke survivors receiving rehabilitative therapies

Abstract

The modified Nottingham Extended ADL Scale and Frenchay Activities Index are both valid outcome measures but the modified Nottingham Extended ADL Scale is more responsive than the Frenchay Activities Index. While simultaneously considering the properties of responsiveness and validity, the modified Nottingham Extended ADL Scale may be a relatively sound measure of instrumental ADL function in stroke patients receiving rehabilitation.
