Serial subtraction tasks (Subtract), reading tasks(Read), auditory response naming questions (Audible), and visual confrontation naming pictures (Visual) conditions were used as a dual-cognitive task. The first two TUG tests were used as a control then, participants performed two trials in random order for each of the four distinct dual cognitive tasks. Each participant performed the TUG test 10 times. The QTUG body-worn sensors were applied on participant’s shins to record data for temporal and spatial gait parameters. The Activities-specific Balance Confidence Scale (ABC) and Screening Assessment for Falls Evaluation (SAFE) tests were administered. Participant’s demographic data included height, weight, BMI, gender, fall history for 12 months, number ofmedications, education, and age.
Participants needed to follow three step commands and have no history of falls inthe past 30 days. Inclusion criteria: theability to stand and ambulate without an assistive device, having no orthopedic surgical procedures in the previous six weeks, living independently in the community, demonstrating corrected vision and ability to read, sufficient auditory function to carry on a conversation and ability to follow directions. Methods: Participants aged 65 and older were recruited from two communities in Iowa and Wisconsin. Background and Purpose: The purpose of this study was to determine how different cognitive dual-tasks impact gaitvariability in community-dwelling adults using the Quantitative Timed Up and Go (QTUG).
