• University of Tennessee registered feasibility trial: using AI and wearable devices to prescribe exercise for older adults and observe changes in depression and anxiety

  This is an early feasibility design using AI and wearable devices for exercise prescription and monitoring of mental health indicators (depression, anxiety) in older adults, following the U.S. National Institutes of Health (NIH) Stage Model 1b, focused on verifying feasibility rather than efficacy.

University of Tennessee registered feasibility trial: using AI and wearable devices to prescribe exercise for older adults and observe changes in depression and anxiety

Background research | Source materials archived | Source date: 2026-08-17

Event: Registration information shows: the research institution is The University of Tennessee, Knoxville, registration number NCT07768670, status is RECRUITING (recruiting), first posted date August 17, 2026, last update posted date August 20, 2026. Estimated start date October 1, 2026, primary completion date December 20, 2026, completion date December 31, 2026, all estimated. Study type is interventional, single-arm, no masking (masking: NONE), primary purpose is prevention, planned enrollment 20 participants. The intervention is an investigator-developed sFitRx fitness app plus Fitbit Flex 2 tracker: the app generates daily and weekly exercise prescriptions based on participants' daily step goals, physical activity data collected by the Fitbit Flex 2 in the previous week, and current fitness and health status collected by the app itself, and provides video demonstrations of warm-up and aerobic, resistance, balance, and flexibility exercises; prescriptions are progressively adjusted and are based on self-determination theory (SDT) and behavior change techniques (BCTs, such as goal setting, self-monitoring, graded tasks, and modeling). Primary outcomes include recruitment, enrollment, withdrawal rate, retention, adherence, and assessment with Weiner et al. (2017) Feasibility of Intervention Measure (FIM), Acceptability of Intervention Measure (AIM), and Intervention Appropriateness Measure (IAM); reported Cronbach's alpha for AIM and IAM were 0.89 and 0.87, respectively. Secondary outcomes include Fitbit daily steps, the Physical Activity Scale for the Elderly (PASE), depression measured with PHQ-8, anxiety measured with the Geriatric Anxiety Scale (GAS), and quality of life measured with the Older People's Quality of Life Questionnaire (OPQOL-Brief), measured at baseline Week 0 and Week 10 follow-up. Funding, sponsor type, and conflict of interest information were not shown in the provided registration text.

Source statement: No company framing. The study was registered on ClinicalTrials.gov by The University of Tennessee, Knoxville as the organizing entity; it is an academic institution research registration, and no corporate statement appears.

Why it matters: The University of Tennessee, Knoxville has registered a single-arm feasibility trial (NCT07768670) on ClinicalTrials.gov, planning to recruit 20 older adults to test the feasibility, acceptability, and appropriateness of generating personalized exercise prescriptions via a mobile app driven by wearable devices and AI (artificial intelligence), and to preliminarily observe changes in physical activity, sleep, depression and anxiety, and quality of life. The study has not yet started, has a small sample, and has no control group; it is an early feasibility study, and efficacy cannot be judged from it.

Editorial judgment: This is an early feasibility design using AI and wearable devices for exercise prescription and monitoring of mental health indicators (depression, anxiety) in older adults, following the U.S. National Institutes of Health (NIH) Stage Model 1b, focused on verifying feasibility rather than efficacy. Its significance for the industry is that it measures emotional and psychological indicators as secondary outcomes of an exercise intervention, representing a registration-level starting point for evidence in the 'physical activity—psychological state' intersection. Note that registration status, expected dates, and enrollment numbers may all change; single-arm, 20 participants, no control, cannot distinguish intervention effects from natural fluctuation or measurement effects.

Follow-up observation: Whether the study's result data are published on ClinicalTrials.gov or in journals; whether similar AI-driven exercise interventions for older adults have controlled designs or larger-sample studies; whether regulatory or industry standards emerge that bind evaluation of physical activity digital interventions to mental health outcomes
