title: Outcome parameters in spinal cord injury research: a systematic review using the International Classification of Functioning, Disability and Health (ICF) as a reference.
abstract: OBJECTIVE
  This study is part of the development of an International Classification of Functioning, Disability and Health (ICF) Core Set for spinal cord injury (SCI). Its specific objectives were to identify outcome parameters reported in published studies on individuals with SCI in the early post-acute and chronic situation, and to identify and quantify the concepts of the reported parameters using the ICF as a reference.
  
  
  METHODS
  Electronic searches of Medline, EMBASE, PsycINFO and CINAHL from 2001 to 2005 were carried out. All outcome parameters and their underlying concepts were retrieved from the included studies. These concepts were linked to categories of the ICF using standardized rules.
  
  
  RESULTS
  From the 6681 abstracts retrieved, 2205 were randomly selected (33.0%) and 281 studies met the inclusion criteria (12.7%). A total number of 5217 concepts were retrieved from standardized and non-standardized measures, of which 4049 (77.6%) could be linked to 175 different ICF categories: 56 out of 114 Body Functions, 19 out of 56 Body Structures, 62 out of 118 Activities and Participation and 38 out of 74 Environmental Factors categories. Second-level categories reported in >20% of all studies were pain, remunerative employment, health services, systems and policies, school education and higher education.
  
  
  CONCLUSIONS
  The ICF provides a valuable reference to identify and quantify the concepts of measures focusing on SCI in the early post-acute and chronic situation. The findings show a great diversity in the consequences of SCI and underscore the importance of social participation and environment for people with SCI.
