This study aims to evaluate the feasibility, usability, and clinical effectiveness of a digital rehabilitation platform in adult patients discharged from the intensive care unit (ICU). Adult patients aged 19 years or older who stayed in the ICU for more than 48 hours and are capable of using a smartphone will be enrolled from two tertiary hospitals in South Korea.
Participants will receive individualized rehabilitation programs using a digital rehabilitation platform ("Tuntun Rehabilitation Assistant") based on their functional status. Rehabilitation will be conducted once daily for up to 30 minutes per session. Physical and cognitive function outcomes will be assessed at baseline, two weeks after intervention initiation, at hospital discharge, and during follow-up when applicable.
This prospective cohort study will investigate changes in physical function, mobility, cognitive status, and quality of life, as well as platform usage and safety-related events, to determine the clinical usefulness of digital rehabilitation for ICU survivors.
