This randomized trial tested a 6 month intervention of computer network vs a control group (standard care) to improve quality of life and health status for traumatic brain injury (TBI) patients and their caregivers. The network, termed the Trauma Recovery Support System (TRSS), consisted of a central computer system connected via modem to a personal computer in the caregiver's home. Users could access via the Internet special modules and communication services to help them cope with their new roles as caregivers and with accompanying social isolation. These modules were an on-line discussion group, an "ask an expert questions" function, a database of previously asked questions with answers, a database of community resources, and a reference library.
