A search was conducted using the databases MEDLINE, CINAHL, and SPORTDiscus from 1966 to August 2006. Two of the authors (E.H. and C.C) independently hand searched recent journals and personal files for publications, posters, or abstracts. In addition, the reference lists in review articles were cross-checked and the individual names of each special test were questioned with the use of MEDLINE.
