Structured Self-Talk and Wearable-Assisted Walking for Physical Activity and Function in Older Adults
Effects of Integrating Self-Talk Strategies With Wearable Technology on Physical Activity, Functional Performance, and Psychological Determinants in Community-Dwelling Older Adults: A Randomized Controlled Trial
The goal of this randomized clinical trial was to examine whether adding structured self-talk to wearable-assisted walking could support physical activity and physical function in community-dwelling older adults. The study also examined whether wearable-assisted walking provided benefits compared with a walking program without wearable feedback.
Participants were randomly assigned to one of three groups for 12 weeks: (1) wearable-assisted walking combined with structured self-talk, (2) wearable-assisted walking without structured self-talk, or (3) a walking-only active control condition. All groups followed the same moderate-intensity walking schedule.
The main questions were whether wearable-assisted walking was associated with better physical activity and functional performance than walking alone, and whether adding structured self-talk provided additional benefits beyond wearable-assisted walking. Physical activity, functional performance, and other protocol-specified health-related measures were assessed before and after the intervention.

Descrição detalhada
This was a 12-week, three-arm, parallel-group randomized controlled trial conducted in community-dwelling older adults. Sixty participants were allocated in a 1:1:1 ratio to an integrated intervention group, a technology-assisted group, or an active control group.
All three groups followed the same moderate-intensity walking prescription consisting of three 30-minute sessions per week for 12 weeks, with exercise intensity guided by a rating of perceived exertion of 11-13. The integrated intervention group used a wearable activity device that provided real-time activity feedback and also received structured self-talk training. The self-talk component was designed to help participants use task-focused and motivational statements during walking and progressed from awareness and instruction to regulation and self-directed use over the intervention period.
The technology-assisted group followed the same walking prescription and used the same wearable activity device but did not receive structured self-talk training. The active control group followed the same walking prescription without wearable feedback or structured self-talk and recorded exercise participation using a paper-based log.
Assessments were conducted at baseline and after completion of the 12-week intervention. Outcome assessors were blinded to group allocation. The study was designed to distinguish the effects associated with wearable-assisted walking from any additional effects associated with adding structured self-talk.

|---|---|

Experimental: Integrated Intervention Group
Participants received a 12-week moderate-intensity walking program combined with wearable-based activity feedback and structured self-talk training.
Walking was prescribed three times per week for 30 minutes per session at a rating of perceived exertion of 11-13.
The wearable device provided real-time step feedback and haptic alerts.
Structured self-talk training was provided weekly and progressed through awareness, acquisition, regulation, and maintenance stages.
|
Participants performed moderate-intensity walking three times per week for 30 minutes per session over 12 weeks.
Exercise intensity was prescribed at a rating of perceived exertion (RPE) of 11-13.
This standardized walking program was provided to participants in all three study groups.
A wrist-worn wearable activity device was used to provide real-time step feedback and haptic vibration alerts during the 12-week walking intervention.
The device was used as a behavioral feedback tool to support walking participation.
Data from the intervention wearable device were not used as the research outcome measure.
Participants received weekly structured self-talk training throughout the 12-week intervention.
The training was delivered by trained instructors and progressed through four stages: awareness, acquisition, regulation, and maintenance.
Participants were taught to use structured motivational and instructional self-talk during walking and in response to wearable-generated feedback.
Standardized scripts and fidelity checklists were used to support consistent intervention delivery.

Comparador Ativo: Technology-Assisted Group
Participants received the same 12-week moderate-intensity walking program and used the same wearable device for real-time activity feedback but did not receive structured self-talk training.
Brief weekly contacts were limited to device operation, battery status, and wearing compliance and did not include psychological strategy training.

Comparador Ativo: Active Control Group
Participants received the same 12-week moderate-intensity walking program without wearable-based activity feedback or structured self-talk training.
Participants recorded the date, duration, and rating of perceived exertion of each walking session using a paper-based exercise log.
