MS patient management: the Analog Model.

The Analog Model was developed for use in patients with multiple sclerosis (MS) at an international roundtable meeting in 2001. Three key disease components are monitored, namely relapses, disability progression and magnetic resonance imaging activity. Its use provides a rapid, straightforward means of assessing the efficacy of disease-modifying therapy and the need for treatment change. The Analog Model thus assists in optimising the management of patients with MS.
