Effectiveness of a Smartphone Chatbot to Improve Exercise Adherence in Older Adults (EXEBOT)
Effectiveness of a Smartphone-Based Chatbot on Adherence to a Home-Based Multicomponent Exercise Program and Physical Function in Older Adults: A Randomized Controlled Trial
This randomized controlled trial aims to evaluate the effectiveness of a smartphone-based chatbot in improving adherence to a 12-week home-based multicomponent exercise program in community-dwelling older adults. Participants will be randomly assigned to receive either a chatbot-supported exercise program delivered through Telegram or an equivalent paper-based exercise program. Both groups will perform the same exercise program, including strength, balance, flexibility, and walking exercises. The primary outcome is exercise adherence. Secondary outcomes include physical function, physical activity, participant satisfaction, usability of the chatbot, and adverse events. The study seeks to determine whether chatbot-based support can enhance adherence and improve health outcomes in older adults.

Population aging is associated with declines in physical function, mobility, and independence. Home-based multicomponent exercise programs are effective strategies to maintain physical function and reduce the risk of disability in older adults; however, adherence to exercise programs remains a major challenge, particularly when exercises are performed without direct supervision. Effectiveness of a Smartphone-Based Chatbot on Adherence to a Home-Based Multicomponent Exercise Program and Physical Function in Older Adults: A Randomized Controlled Trial addresses this challenge by evaluating a digital intervention specifically designed to support exercise adherence.
This study is a two-arm, parallel-group randomized controlled trial conducted in community-dwelling adults aged 60 years and older. Participants are randomly allocated in a 1:1 ratio to either a chatbot-supported exercise program or a paper-based exercise program. Both groups receive the same 12-week home-based multicomponent exercise program, consisting of three exercise sessions per week. The intervention includes strength, balance, flexibility, and walking exercises with a predefined progression throughout the program.
Participants assigned to the intervention group receive exercise prescriptions through a Telegram-based chatbot. In addition to delivering the exercise program, the chatbot provides instructional videos, automated reminders, exercise monitoring, adherence tracking, scheduling adjustments, and feedback based on participants' reported exercise completion. Participants allocated to the control group receive the same exercise program in a printed booklet together with a paper calendar for recording completed sessions. Both groups receive standardized follow-up telephone calls during the intervention period.
The primary outcome is exercise adherence, defined as the percentage of prescribed exercise sessions completed during the 12-week intervention. Participants are also classified according to whether they achieve at least 80% adherence to the prescribed sessions. Secondary outcomes include physical function assessed using the Short Physical Performance Battery (SPPB), 4-meter walking test, Five Times Sit-to-Stand Test (FTSST), and Timed Up and Go (TUG) test. Additional outcomes include physical activity measured with the International Physical Activity Questionnaire for Older Adults (IPAQ-E), participant satisfaction, perceived usability of the chatbot, and adverse events.
The study will provide evidence regarding the effectiveness of chatbot-supported exercise interventions for promoting adherence to home-based exercise programs among older adults. If effective, this approach may represent a scalable and accessible strategy to support healthy aging and the implementation of exercise programs in community settings.

Eksperymentalny: Chatbot-Supported Exercise Program
Participants will receive a 12-week home-based multicomponent exercise program delivered through a Telegram-based chatbot. The program includes three exercise sessions per week consisting of strength, balance, flexibility, and walking exercises with a predefined progression. The chatbot provides exercise prescriptions, instructional videos, reminders, monitoring of exercise completion, scheduling adjustments, and automated feedback to support adherence. |

Aktywny komparator: Paper-Based Exercise Program
Participants will receive a 12-week home-based multicomponent exercise program in a printed booklet. The program includes three exercise sessions per week consisting of strength, balance, flexibility, and walking exercises with a predefined progression. Participants will also receive a paper calendar to record exercise completion. No chatbot-based reminders, monitoring, or automated feedback will be provided. Participants will receive the same exercise content, dosage, and progression as the experimental group. |

Exercise Adherence
Ramy czasowe: 12 weeks
|
Exercise adherence will be measured as the percentage of the 36 prescribed exercise sessions completed during the 12-week intervention period. Adherence will be calculated from participant exercise records and expressed as a continuous percentage value. |

Short Physical Performance Battery (SPPB)
Ramy czasowe: Baseline and 12 weeks
|
Physical function assessed using the Short Physical Performance Battery. Scores range from 0 to 12, with higher scores indicating better physical performance. |
Baseline and 12 weeks

Timed Up and Go Test (TUG)
Ramy czasowe: Baseline and 12 weeks

Physical Activity Level
Ramy czasowe: Baseline and 12 weeks
|
Physical activity will be assessed using the International Physical Activity Questionnaire for the Elderly (IPAQ-E). Physical activity is quantified as MET-minutes per week (MET-min/week), calculated from the frequency and duration of walking, moderate-intensity, and vigorous-intensity physical activities performed during the previous week. The questionnaire does not have a predefined minimum or maximum score, as results are reported as a continuous measure of energy expenditure. A practical minimum score is 0 MET-min/week, while no upper limit is defined. Higher scores indicate higher levels of physical activity and therefore a better outcome. |
Baseline and 12 weeks
|
|
Participant Satisfaction
Ramy czasowe: 12 weeks
|
Participant satisfaction with the intervention will be assessed using the Client Satisfaction Questionnaire-8 (CSQ-8). The CSQ-8 consists of 8 items, each scored on a 4-point Likert scale. Total scores range from 8 to 32 points, with higher scores indicating greater satisfaction with the intervention and therefore a better outcome. |

Chatbot Usability
Ramy czasowe: 12 weeks
|
Perceived usability of the chatbot will be assessed using the System Usability Scale (SUS). The SUS is a 10-item questionnaire with responses scored on a 5-point Likert scale. Total scores range from 0 to 100, with higher scores indicating better perceived usability of the chatbot and therefore a better outcome. This outcome will be assessed only in participants allocated to the chatbot intervention group. |
