Can a phone app stop muscle loss in seniors?
NCT ID NCT07230210
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a 12-week smartphone-based program can help older adults at risk of sarcopenia (muscle loss) maintain muscle mass and strength. The program includes exercise videos, nutrition tips, daily reminders, and a point system to keep users engaged. Sixty participants will be split into two groups: one using the app, the other receiving standard care. The goal is to see if the app improves muscle mass, physical performance, and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Line Bot platform delivering exercise videos, nutrition education, reminders, and logging
- What this could lead to
- If it works, this could offer a practical, home-based way to prevent muscle decline in older adults.
- What could go wrong
- This is a small, early-stage trial with only 60 participants, so results may not apply to everyone. The program relies on smartphone use, which may limit who can benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria Score ≥ 11 on the SARC-CalF questionnaire, indicating risk of sarcopenia. No evident functional impairment in the limbs and able to complete handgrip strength, walking speed, and muscle mass assessments. Possesses basic reading, writing, and calculation abilities sufficient to understand study-related materials and complete informed consent and daily logs. Owns a smartphone and has used it for at least one year, with basic operational ability (e.g., sending and receiving LINE messages, scanning QR codes). Exclusion Criteria Self-reported functional impairment in any limb. Requires assistance from a wheelchair, walker, or cane for ambulation. Has an implanted cardiac pacemaker. Currently participating in, or planning to participate in, other physical training courses or nutrition programs during the study period.
