Introduction

Abstract

Spasticity – as a component of the upper motor neuron syndrome – is a frequently encountered clinical condition. Spasticity may be either useful – by compensating decrease in motor strength – or harmful – by limiting both passive and active motion and, in the extreme, by leading to irreducible contractures and deformities – or as in most cases and harmful and useful in the same patient. A large population of adults and children in developing countries and in wealthy societies as well is suffering from this locomotor disability. Caring involves a large number and variety of actors.
