研究概览
简要总结
The goal of this clinical trial is to prevent functional decline and improve mobility in healthy older adults aged 65 and over. The main questions it aims to answer are:
What is the effect of individualized dual-task training on functional balance and mobility compared to standard training? Does personalized sensory and cognitive training significantly reduce the dual-task cost during walking tasks? Researchers will compare the Individualized Dual-Task Group to a Standardized Dual-Task Group and a Single-Task Control Group to see if personalized adjustments in sensory and cognitive loads lead to superior improvements in balance, gait speed, and motor-cognitive interference.
Participants will:
Complete an initial assessment of motor and cognitive capacities to determine individual baseline levels.
Participate in a supervised exercise program 3 days a week for 8 weeks, with each session lasting 40-45 minutes.
Perform motor tasks such as walking, obstacle crossing, and balance exercises while simultaneously engaging in cognitive tasks (e.g., counting, verbal fluency).
(For the individualized group) Undergo weekly adjustments in exercise difficulty, including sensory manipulations like surface changes and head movements based on their performance.

盲法说明
The study is a single-blind trial. While participants and the physical therapist providing the intervention cannot be blinded to the group assignments due to the nature of the exercises, the outcome assessor who performs all baseline and post-intervention measurements will be kept blinded to the group allocations. Data analysis will also be conducted by a researcher blinded to the group codes.

研究组 & 干预措施
Standardized Dual-Task Group
Participants will receive a standard (fixed-progression) dual-task training program 3 days a week for 8 weeks.
干预措施: Standardized Dual-Task Training (Behavioral)
Individualized Dual-Task Group
Participants will receive individualized cognitive-motor dual-task training 3 days a week for 8 weeks. Exercises are adjusted weekly based on individual performance levels.
干预措施: Individualized Dual-Task Training (Behavioral)
Single-Task Control Group
Participants will perform single motor tasks (walking or balance exercises only) without simultaneous cognitive tasks for the same duration.
干预措施: Single-Task Motor Training (Behavioral)
结局指标
主要结局
Dual-Task Cost (DTC) of Functional Mobility
时间窗: Baseline and at the end of the 8-week intervention.
Dual-Task Cost (DTC) will be calculated based on the Timed Up and Go (TUG) test performance. DTC represents the percentage change in TUG time during a cognitive-motor dual-task condition (e.g., walking while counting backwards) compared to a single-task condition (walking only). The formula is: DTC = \[(Dual-Task Time - Single-Task Time) / Single-Task Time\] X 100. A higher percentage indicates greater interference and poorer dual-task performance.
次要结局
- Berg Balance Scale (BBS)(Baseline and at the end of the 8-week intervention.)
- 10-Meter Walk Test (10MWT)(Baseline and at the end of the 8-week intervention.)
- Falls Efficacy Scale-International (FES-I)(Baseline and at the end of the 8-week intervention.)
- Montreal Cognitive Assessment (MoCA)(Baseline and at the end of the 8-week intervention.)
