[Epidemiology and clinical assessment of spasticity in multiple sclerosis]

Abstract

Spasticity is a commonly seen symptom in patients with multiple sclerosis (MS). The vast majority of patients will suffer from this symptom during the course of the disease, and one- third of patients considers that spasticity contributes to a greater part of their disability. The symptom is frequently disabling. It can, however, allow some activities to be performed. Treatment of the symptom is sometimes deleterious, which is why strict assessment of the consequences of spasticity and anticipation of the outcome of antispastic treatment are necessary. Clinical scales, such as the Ashworth and Tardieu scales, are used in clinical practice. The essential element is not, however, assessment of the symptom, but its repercussions on activities of everyday life. It is important to make a list of what patients consider to be disabling situations to verify that they are truly consequences of spasticity. Considering the heterogeneity of clinical expression of spasticity in patients with MS, the use of a scale such as goal attainment scaling (GAS) can probably be totally adapted for the assessment of the effects of antispastic treatment.
