What is a Spasticity? Spasticity is a motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes with exaggerated tendon reflexes, resulting from hyper excitability of the stretch , as one factor of the upper motor neuron syndrome. Spasticity is loss in muscle movement patterns so that muscles contract all at once. Muscle movements…
