A Dyadic Approach for a Remote Physical Activity Intervention in Adults With AD and Their Caregivers
The objective of this study is to compare the effectiveness of 2 intervention delivery strategies for increasing moderate physical activity (MPA), real-time group video conferencing (RGV) vs. enhanced usual care (EUC), in community dwelling adults with Alzheimer's diseases (AD) and their caregiver (dyads) over 18 mos. (6 mos. active, 6 mos. maintenance, 6 mos. no contact). The primary outcome is to compare total MPA (min/wk.), assessed using ActiGraph, in adults with AD from baseline to 6 mos. Secondary aims for the Adults with AD are to compare MPA (min/wk), sedentary time (min/wk.), percentage meeting 150 min/wk. goal, functional fitness, activities of daily living (basic/instrumental), quality of life, residential transitions, and cognitive function across 18 months between RGV and EUC. Secondary aims for the caregivers are to compare total MPA (min/wk.), sedentary time (min/wk.), functional fitness, quality of life, caregiver burden across 18 months between RGV and EUC. Additionally, as an exploratory aim, this study will evaluate the influence of process variables/participant characteristics on MPA in adults with AD and their caregiver across 6, 12 \& 18 mos.: age, sex, BMI, attendance (exercise/support sessions), use of recorded videos, PA self-monitoring, peer interactions during group sessions, caregiver support, type and quality of dyadic relationship, and number of caregivers.
⁃ Adults with AD -
• Very mild to moderate dementia
• Age ≥ 55 yrs
• Low-risk of falls
• Ability to participate in MPA, e.g., walk including with an assistive device, as verified PCP clearance.
• Ability to communicate verbally.
• Vision and hearing sufficient to safely comply with the intervention program as verified by PCP clearance.
• Reside at home and receive support from a caregiver.
• Internet access in the home.
⁃ Caregivers-
• Age ≥18 yrs.
• Spends at least 20 hrs./wk. with the adult with AD.
