简要总结
This study aims to compare the effects of remote versus in-person exercise interventions on physical function, balance, gait stability, and fall efficacy in pre-frail older adults aged 65 years and above. Participants are randomly assigned to either a remote exercise group, an in-person exercise group, or a control group. The exercise intervention includes balance, strength, and gait training conducted twice weekly for eight weeks. The control group receives educational materials on physical activity. The primary outcome measures include assessments of balance, lower limb strength, gait ability, and fall efficacy. This study seeks to determine if remote exercise is as effective as in-person exercise in enhancing physical function in pre-frail older adults, potentially providing a feasible alternative to traditional in-person programs and addressing barriers such as limited mobility and access to exercise facilities.

结局指标
主要结局
Balance ability
时间窗: Baseline and post-intervention at 8 weeks
Balance performance will be assessed using the Timed Up and Go (TUG) test and Berg Balance Scale (BBS). The TUG measures the time taken for a participant to stand up from a chair, walk three meters, turn around, walk back, and sit down. The BBS is a comprehensive assessment of balance ability during various tasks.
Lower Limb Strength
时间窗: Baseline and post-intervention at 8 weeks
Lower limb strength will be evaluated using the Five Times Sit-to-Stand Test (FTSTS) and the 30-Second Chair Stand Test (30SCS). The FTSTS measures the time it takes for participants to rise from a chair five times, and the 30SCS measures the number of times participants can rise from a chair in 30 seconds.
Gait Ability
时间窗: Baseline and post-intervention at 8 weeks
Gait ability will be assessed using the Dynamic Gait Index (DGI) and the 10-Meter Walk Test (10MWT). The DGI assesses participants' ability to modify balance while walking in response to external demands, and the 10MWT measures the time taken to walk 10 meters at a comfortable speed.
Fall Efficacy
时间窗: Baseline and post-intervention at 8 weeks
Fall efficacy will be measured using the Modified Falls Efficacy Scale (MFES). This scale evaluates participants' confidence in performing daily activities without falling, providing an indication of fall-related self-efficacy.
