Study Overview
Brief Summary
The objective of this study is to investigate psychometric properties of dual-task walking assessments and compare effects of three types of dual-task balance interventions on dual-task walking for stroke patients.
Detailed Description
English Synopsis
I. Title of Study:
Immediate and retained effects of three types of dual-task interventions on dual-task walking performance of stroke patients: psychometric study and 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 three types of dual-task balance interventions on dual-task walking for stroke patients. Specifically, we will investigate psychometric properties (i.e. reliability, validity, and responsiveness) of dual-task walking assessments with various levels of difficulty for stroke individuals (Aim 1). The second aim of this study is to compare the immediate and retained effects of combined motor and cognitive dual-task training (MCDTT), motor dual-task training (MDTT), and cognitive dual-task training (CDTT) on dual-task gait and cognitive performance after stroke (Aim 2). The third aim of this study is to elucidate the changed CMI pattern of stroke patients after dual-task interventions (Aim 3).

Inclusion Criteria
- •(1) first-ever stroke with onset duration more than 3 months
- •(2) able to walk 10 m

Outcomes
Primary Outcomes
gait speed
Time Frame: 10 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.
composite score
Time Frame: 10 minutes
For all the cognitive tasks, we will calculate a composite score for cognitive-task performance by dividing the accuracy (% correct responses) with the reaction time of correct answers (milliseconds), which accounts for speed-accuracy tradeoffs in the overall dual-task effect.
Secondary Outcomes
- Berg Balance Scale (BBS).(5-10 minutes)
- Chair Stand Test (CS).(2 minutes)
- Patient Global Impression of Change Scale (PGIC).(1 minutes)
- Muscle Strength of Lower-Extremity.(10 minutes)
- Mini-Balance Evaluation Systems Test (Mini-BESTest).(10 minutes)
- Functional Gait Assessment (FGA).(10 minutes)
- Timed Up and Go Test (TUG)(2 minutes)
- Activity-specific Balance Confidence Scale (ABC).(2 minutes)
