Conceptual illustration of improving physical function in older sepsis survivors. We hypothesize that patients experience early modest physical function improvement with early rehabilitation in the hospital. Upon discharge home, however, physical function plateaus or declines over time (red dashed line) due to limited physical activity. The home-based app-guided exercise training may help the older survivors improve physical function long-term (green dashed line). ICU = intensive care unit, OT = occupational therapy.
