Brief Summary

The purpose of this single-blinded three-armed randomized controlled trial is to investigate the effect of different task prioritization during dual task training on dual task performance.

Detailed Description

Introduction: Many activities of daily livings involve performing two tasks simultaneously, i.e. dual tasking. Performing dual task increases the demand on attentional resources, which may further decrease the dual task performance, especially in older adults. According to capacity sharing theory, the two tasks compete and influence with each other due to limited attention and information processing capacity. It has been noted that task prioritization during dual tasking may influence the dual task performance. Previous study indicated that supraposture-focus strategy resulted in better posture and task performance in older people. On the other hand, it is known that dual task training improved dual task performance. However, the effects of applying task prioritization during dual task training have not yet been investigated. Therefore, the purpose of this study is to investigate the effect of different task prioritization during dual task training on dual task performance.

Methods: Participants will be randomized into three groups: posture-focus, supraposture-focus and control group. Participants will receive a total of 12 sessions of cognitive dual task training with different prioritization strategies, i.e. prioritization on posture, cognitive or neither task. Walking and task performance during dual task walking, executive function, and balance performance will be assessed before and after the interventions (pre- and post-test).

Study Groups

Posture-focus group

Participants will be instructed to pay most attention to practice the posture task during training

Group Type: EXPERIMENTAL

Dual task training

Intervention Type: OTHER

All participants will receive cognitive dual task training for 30 min/session, 2-3 sessions/week for 4-6 weeks (a total of 12 sessions). The cognitive dual task training includes 15 min of cognitive task combining with standing task and 15 min of cognitive task combining with walking task. The differences among group are the instructions of task prioritization given by the therapist

Supraposture-focus group

Participants will be instructed to pay most attention to practice the cognitive task during training

Group Type: EXPERIMENTAL

Dual task training

Intervention Type: OTHER

All participants will receive cognitive dual task training for 30 min/session, 2-3 sessions/week for 4-6 weeks (a total of 12 sessions). The cognitive dual task training includes 15 min of cognitive task combining with standing task and 15 min of cognitive task combining with walking task. The differences among group are the instructions of task prioritization given by the therapist

Control group

Participants will not be receive any instruction to prioritize either task

Group Type: ACTIVE_COMPARATOR

Dual task training

Intervention Type: OTHER

All participants will receive cognitive dual task training for 30 min/session, 2-3 sessions/week for 4-6 weeks (a total of 12 sessions). The cognitive dual task training includes 15 min of cognitive task combining with standing task and 15 min of cognitive task combining with walking task. The differences among group are the instructions of task prioritization given by the therapist
