The major impetus of basic spinal cord injury (SCI) research is that therapeutic interventions can be devised to prevent or reduce disability. For years, there was doubt about the prospect that any effective treatment could ever be developed. This view is based primarily on the notion that once spinal cord trauma has occurred, the damage is done and outcome is determined at the moment of impact. The potential for any therapeutic intervention to reverse the injury process or to reduce the damage has been, understandably, doubtful. Numerous therapeutic interventions had claimed to be successful in animal models, yet none had been confirmed in patients with SCI. Recently, however, the Second National Spinal Cord Injury Study (NASCIS II) has altered such pessimistic viewpoints.1 This study is a landmark achievement in pharmacological intervention of SCI. For the first time, a multicentre placebo-controlled, double-blind trial, using a well designed protocol and sound statistical analysis, shows that an acute traumatic insult to the spinal cord is treatable if an appropriate therapeutic agent is administered within a therapeutic window. NASCIS II was based on earlier elegant investigations in animal models that showed methylprednisolone, a glucocorticoid, to be effective in ameliorating vascular, metabolic, pathological, and functional consequences of traumatic SCI. 2 -9 Confirmation of the animal studies in a human trial using a rigorously designed protocol has significant laboratory and clinical implications. It establishes the precedent that the therapeutic success of SCI models in animals can be duplicated in patients with a similar disorder. It also diminishes the pessimism concerning the applicability of animal models to human diseases affecting the central nervous system, in particular, central nervous system (CNS) trauma.10. II The success of NASCIS II also legitimises therapeutic trials in animal models of SCI. Research projects exclusively devoted to therapeutic trials in animal models are usually not considered to be meritorious by review panels from various funding agencies. The
