Physical functioning measures a person’s ability to do everyday tasks. Mental functioning measures a person’s ability to think and reason. All networks had higher physical functioning scores among their injured employees than non-network. Most network patients had better or equal mental functioning scores as well. Both of these scores among network injured employees have consistently been higher than those of non-network injured employees and the U.S. population since 2012.
