The Miami Project and UM Department of Neurological Surgery are part of the North American Clinical Trials Network (NACTN). NACTN is a network of institutions that is developing the infrastructure, methods, and skilled personnel needed to conduct trials for SCI. Presently, the collaborative centers are collecting natural history data from newly injured people to determine the medical and rehabilitative outcomes and complications that occur in people receiving standard of care. Participants are evaluated for one year post-injury. The Miami Project has already enrolled more than 35 people to this registry. This information will help determine the design of SCI clinical trials because we will better understand complications that are risky for interventions at specific times post-injury and what degree of spontaneous recovery would be considered normal for different types of injuries.
