Digital Self‐Assessment of Physical Performance to Promote Independence in Older Adults: Development, Usability, and Validity

The tool provides self-directed, comprehensive assessments and delivers intuitive comparative data against age- and sex-matched norms, thereby enabling autonomous health management. Despite variable user experience, the tool demonstrated acceptable usability, with most participants recognizing its utility and perceiving the potential for home use. Further refinements in usability, accuracy, and technical simplification are needed. With these improvements, the tool could harness these assessment results to deliver tailored exercise programs and evolve into a comprehensive prevention and rehabilitation resource for older adults.
