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

Early research reported that older adults who stopped walking when they began a conversation were more likely to fall in the future. As a systematic measure of dual-task performance, Verghese and colleagues developed the Walking While Talking (WWT) test, in which a person walks at a normal pace while reciting alternate letters of the alphabet. The present paper highlights key findings from the 2 decades of research using the WWT test.
