AbstractAlthough the citation index of an article is not a direct measure of its quality or importance, it is a measure of recognition that may suggest its impact on the scientific community. This study was undertaken to examine the characteristics of the top 100 most frequently cited articles (so-called "citation classics") on traumatic spinal cord injury (SCI) that were published between 1986 and 2003, and to compare this selected professional literature with the consumers' perspective on the key issues in SCI research. The 100 top-cited articles on traumatic SCI were identified using the Internet database of the Science Citation Index Expanded and the Web of Science with the terms "spinal cord injury" and "spinal cord injuries." Meeting abstracts, letters, and editorials were excluded. No language restriction was applied. From a consumers' perspective, the areas of greatest interest for people with SCI as reported in two previous large-scale surveys include motor function, bowel and bladder control, sexual function, and pain. The final list of citation classics on traumatic SCI included 82 original articles and 18 article reviews, which were cited 146 times on average. Topics on basic science (63%) were more frequent than clinical studies (37%). The years of publication were distributed in a bell-shape curve with a peak between 1992 and 1994. North American and European centers (99%) led the list of the citation classics. Most of the top 100 most frequently cited articles on traumatic SCI (63%) explicitly focused on at least one of the topics of greatest interest to individuals with SCI. Motor function was the leading topic in the matching list between professional literature and consumers' perspective. This bibliometric analysis, for the first time, identifies the key features of the citation classics on traumatic SCI between 1986 and 2003, a period that represents one of an unprecedented increase in knowledge in this field. The 100 top-cited peer-reviewed articles have been predominantly focused on basic science SCI research indicating a need for greater bench-to-bedside translational studies in SCI research. Although the body of this top-cited professional literature mostly matches with the consumers' perspective, most of this research has been focused on motor function assessment and recovery following SCI.
