Walking while talking: validation in older adults with lower-limb amputation

Abstract

Background: Walking while talking (WWT) is a dual-task (cognitive and motor) performance test that has not yet been validated in older adults with lower-limb amputation (LLA). WWT is composed of two sections: WWT-simple (walking while reciting every letter of the alphabet) and WWT-complex (walking while reciting every other letter of the alphabet).Objective: To determine the validity, and provide normative data and a new scoring system for the WWT test in older adults with LLA. Study design: Baseline cross-sectional data were collected from 56 community-living older adults ($50 years old) with LLA at rehabilitation hospitals in Vancouver,
