Prior to 2004, very little was known about spinal cord injuries in Canada: their causes, prevalence, severity, or what factors affected how people improved (or didn’t improve) over time after injury. A registry—an organized system to create a centralized repository of information—which follows the progress of people with SCI over a period of time, has the potential to yield valuable information such as which interventions provide the best long-term outcomes for the patient. Unlike clinical trials, which normally involve a smaller sample of participants in an artificially standardized research environment, registries are often much larger with a more representative sample of people, and can give a better idea of what works in a real-world environment.
