Evidence-based medicine is the process of systematically finding, appr
aising, and applying contemporaneous research findings as the basis fo
r clinical decisions. The individual clinician is too busy to perform
this long and arduous task across the whole of their specialty, so the
y must rely on the highest quality reviews available in the literature
. The Cochrane Collaboration is an international network of individual
s preparing, maintaining, and disseminating systematic reviews of tria
ls all health care interventions. We examine the work of the Collabora
tion and the major method it uses to disseminate systematic reviews th
rough the Cochrane Library. The rationale for the Cochrane Movement Di
sorders Group is discussed, and its management structure outlined.
