Effect of Using a Reminder to Encourage Patients to be Active During Their Hospital Stay.

Around 30% of patients aged 65 and over experience functional decline due to hospitalization. Physical inactivity, often without medical justification, is common during hospital stays.This immobility leads to loss of autonomy, muscle strength, and increases post-discharge risks. Slow walking for 25-40 minutes daily significantly improves functional capacity. However, it could be difficult to reach this time of walking due to a lack of physiotherapist in hospital. A vibrating watch may encourage patients to walk or perform strengthening exercises. This simple intervention aims to improve function without requiring additional staff or resources
