Gait-associated dynamic deviations during cognitive dual tasks in physically active adults living with HIV

Abstract

Introduction: Among Human immunodeficiency virus (HIV) complications, individuals living with HIV experience cognitive deterioration that could influence gait and balance in this group. To identify gait variations during dual cognitive tasks equaled to single tasks in those living with HIV.Material and methods: 11 females and 18 male adults (age, 60.31 ± 7.82) diagnosed with HIV were recruited for the current investigation. The study instructed participants to walk 7 meters (single tasks), and the same distance while counting backward from 100 by 3 (dual cognitive tasks). During the activity, parameters, such as gait speed, stride length, and postural sway were gathered with six motion analysis sensors.
