Influence of physical and cognitive capacity on task prioritization during the gait-related dual-task performance in elderly: A comparison

Purpose and objectiveTo find influence of cognitive and physical capacity of elderly on task prioritization during dual-tasking as there is conflicting evidence about whether the elderly prefer posture first or cognition first strategy while doing dual-tasking.Method164 elderly were divided into 4 groups as per their physical and cognitive capacity using MoCA (Montreal Cognitive Assessment) and TUG (Time Up and Go) scores (1-balance affected and cognition normal (BACN), 2 -balance normal and cognition affected (BN CA), 3- balance normal and cognition normal (BN CN), 4- balance affected and cognition affected (BA CA). They were evaluated with n-back test and Time up and go cognitive (TUG-COG) for dual-tasking in motor and cognitive domain respectively. The interference pattern was analyzed for each group.ResultMutual interference was observed in each group.ConclusionMotor and Cognitive capacity of an individual does not affect task prioritization in the elderly.
