Two Decades of the Walking While Talking Test: A Narrative Review

Area of Science:

• Gerontology
• Neuroscience
• Clinical Assessment

Background:

• Early research linked stopping walking during conversation to increased fall risk in older adults.
• The Walking While Talking (WWT) test was developed to systematically measure dual-task performance.
• This review synthesizes two decades of research on the WWT test.

Purpose of the Study:

• To highlight key findings from 20 years of research utilizing the Walking While Talking (WWT) test.
• To review the validity, reliability, and applications of the WWT test.
• To discuss future research directions for the WWT test.

Main Methods:

• A narrative review of literature was conducted.
• Studies published between 2002 and April 2024 using the WWT test were included.
• The review focused on clinical and research settings where participants completed the WWT test.

Main Results:

• The WWT test is an easy-to-administer, valid, and reliable measure of dual-task performance.
• WWT performance is consistently associated with balance, executive function, and memory.
• The test has been used to predict dementia and future falls, and has shown mixed results as an intervention outcome.

Conclusions:

• The WWT test is a valuable tool in clinical and research settings for assessing dual-tasking abilities.
• Future research should expand clinical applications and clarify the longitudinal trajectory of WWT performance.
• The WWT test is a reliable and sensitive measure with broad utility.
