详细描述
English Synopsis
I. Title of Study:
Effects of simultaneous or sequential combination of physical and cognitive training on dual-task walking performance for community-dwelling healthy older adults: a randomized controlled trial.
II. Study Objectives:
The objective of this study is to investigate psychometric properties of dual-task walking assessments and compare effects of simultaneous or sequential combination of physical and cognitive training on dual-task walking and cognitive performance for community-dwelling healthy older adults. Specifically, the study aims to test: 1) the psychometric properties (i.e., test-retest reliability and validity) of dual-task walking outcome measures, 2) the effectiveness of delivering physical and cognitive training via simultaneous or sequential way (physical training concurrent to or followed by a cognitive training) on improving dual-task walking for healthy older adults by using good psychometric properties of outcome measures, 3) the changed CMI pattern of older adults after simultaneous or sequential physical and cognitive training.

研究组 & 干预措施
physical training followed by cognitive training
The physical training followed by cognitive training will receive training at progressively increasing task difficulty 3 times a week for 12 weeks and followed by another 12 weeks without exercise (follow-up).
干预措施: physical training followed by cognitive training (Device)
physical training without cognitive training
The physical training without cognitive training group will receive training at progressively increasing task difficulty 3 times a week for 12 weeks and followed by another 12 weeks without exercise (follow-up).
干预措施: physical training without cognitive training (Device)
physical training concurrent with cognitive training
The physical training concurrent with cognitive training group (the P+C group) will receive training at progressively increasing task difficulty 3 times a week for 12 weeks and followed by another 12 weeks without exercise (follow-up).
干预措施: physical training concurrent with cognitive training (Device)
结局指标
主要结局
composite score
时间窗: 10 minutes
A composite score for cognitive-task performance will be calculated by dividing the accuracy (% correct responses) with the reaction time of correct answers (milliseconds), which accounts for speed-accuracy trade-offs in the overall dual-task effect.
gait speed
时间窗: 5 minutes
Participants will walk 10m at their preferred speed and at fast speed. A 12-meter walkway will be used for walking testing. In order to allow the subjects to have enough distance to accelerate and decelerate, only the time taken to walk the middle 10 meters will be recorded by a stopwatch. The primary gait parameter is gait speed (cm/s) under dual-task walking conditions using the 10 Meter Walking Test,
