About this study
Official title: Effects of Dual Task Prioritization Training on Dual Task Walking in Older People: A Single-blinded Randomized Controlled Trial
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.
Read the 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).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dual task trainingOther
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
| Study group | Role | What they receive |
|---|---|---|
| Posture-focus group | Experimental | Participants will be instructed to pay most attention to practice the posture task during training Receives: Other: Dual task training |
| Supraposture-focus group | Experimental | Participants will be instructed to pay most attention to practice the cognitive task during training Receives: Other: Dual task training |
| Control group | Active comparator | Participants will not be receive any instruction to prioritize either task Receives: Other: Dual task training |

Using GaitUp system to evaluate gait speed during cognitive and motor dual task walking
Measured: Change from baseline dual task walking speed and up to 6 weeks (pre- and post-test)
Dual task walking performance assessment- cadence (steps/min)
Using GaitUp system to evaluate cadence during cognitive and motor dual task walking
Measured: Change from baseline dual task walking cadence and up to 6 weeks (pre- and post-test)
Dual task walking performance assessment- stride length variability (CV, %)

Measured: Change from baseline dual task walking stride time variability and up to 6 weeks (pre- and post-test)
Cognitive dual task walking performance assessment- correct number (times)
The number of the correct answer for serially subtracting "7" from a predefined 3-digit number during cognitive dual task walking task will be recorded.

The number of successfully transferred go pieces from one side to another during motor dual task walking task will be recorded.
Measured: Change from baseline motor dual task walking performance and up to 6 weeks (pre- and post-test)
