Wearable-Assisted Walking for Cognitive Function and Loneliness in Older Adults (WAW-CogLon)
Effects of a Wearable-Assisted Walking Program on Longitudinal Trajectories of Cognitive Function and Loneliness in Older Adults: A Randomized Controlled Trial
Participants in the wearable-assisted walking group were asked to walk five days per week for approximately 30 minutes per session at moderate intensity. An Apple Watch was used to monitor daily steps, walking duration, and estimated energy expenditure. Participants also received weekly feedback to support adherence to the walking program. Participants in the usual-care control group were asked to maintain their usual daily activities and not begin any new structured exercise program during the study period.
Cognitive function was measured using the Montreal Cognitive Assessment, and loneliness was measured using the 8-item UCLA Loneliness Scale. Assessments were conducted at baseline and at weeks 4, 8, and 12. The study also explored whether baseline muscle mass and functional mobility were associated with changes in cognitive function and loneliness over time.
調査の概要
状態
詳細な説明
This randomized controlled trial examined longitudinal changes in cognitive function and loneliness during a 12-week wearable-assisted walking intervention. The intervention combined regular moderate-intensity walking with wearable-device monitoring and weekly feedback. The control group received usual care and maintained their normal daily activities.
The primary outcome was cognitive function, measured using the Montreal Cognitive Assessment. The secondary psychosocial outcome was loneliness, measured using the 8-item UCLA Loneliness Scale. Outcomes were assessed at four time points: baseline, week 4, week 8, and week 12. Baseline appendicular skeletal muscle mass index and timed up-and-go performance were also assessed to examine whether muscle health and functional mobility were associated with individual differences in outcome trajectories.

実験的：Wearable-Assisted Walking Group
Participants assigned to this group received a 12-week wearable-assisted walking intervention.
They were instructed to walk five days per week, with each session lasting approximately 30 minutes at moderate intensity.
A commercially available Apple Watch was used to monitor daily step counts, walking duration, and estimated caloric expenditure.
Weekly feedback was provided through the LINE messaging application and face-to-face check-ins to support self-monitoring, reinforce walking goals, and monitor adherence.

The intervention consisted of a 12-week moderate-intensity walking program supported by a commercially available wearable device.
Participants were instructed to walk five days per week for approximately 30 minutes per session.
Walking intensity was guided by a rating of perceived exertion of 11-13.
An Apple Watch was used to record daily step counts, walking duration, and estimated caloric expenditure.
Weekly feedback was provided through the LINE messaging application and face-to-face check-ins to support self-monitoring, reinforce walking goals, and monitor adherence.

介入なし：Usual-Care Control Group
Participants assigned to this group were instructed to maintain their routine daily activities and typical lifestyle throughout the 12-week study period.
They were asked not to initiate any new structured exercise or rehabilitation program during the study period.
They did not receive wearable devices, structured walking prescriptions, or weekly activity feedback.

Change in Cognitive Function Assessed by the Montreal Cognitive Assessment
時間枠：Baseline, week 4, week 8, and week 12
|
Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), a brief screening tool that evaluates multiple cognitive domains, including visuospatial ability, executive function, attention, memory, language, abstraction, and orientation.
Total scores range from 0 to 30, with higher scores indicating better cognitive performance.

Change in Loneliness Assessed by the 8-item UCLA Loneliness Scale
時間枠：Baseline, week 4, week 8, and week 12
|
Loneliness was assessed using the 8-item UCLA Loneliness Scale (UCLA-8), which measures subjective feelings of loneliness and perceived social disconnection.
Items are rated on a 4-point Likert-type scale, with higher total scores indicating greater loneliness.
