These videos show the changes to social networks after stroke. The moments shown are stroke onset, 3 months, and 6 months after stroke.
The individuals around the patient provide advice, social engagement, and support. Red lines are strong ties, or emotionally close relationships. Black lines are weak ties, or emotionally moderate relationships. An absent line between persons indicate they are strangers and would not recognize one another.
The network dynamics may be divided into four broad categories: shrinking, expanding, social migration, and constant networks. Below are videos from each category.
