Spasticity in head trauma and CVA patients: etiology and management.

Spasticity is a common problem in patients following head trauma and cerebral vascular accident (CVA). Spasticity interferes with mobility and self-care activities which are critical for successful rehabilitative outcomes. While a patient with a spastic muscle about a joint may be able to voluntarily contract the muscle, relaxation of the muscle may be impossible. Severe spasticity can result in joint contractures which further impair function. Shearing movements due to spastic responses precipitate skin breakdown and may disrupt pressure sore repair. In addition, the inability to perform functional activities produces frustration and anxiety for patients and their significant others. The purpose of this article is to review the pathophysiologic basis of spasticity, outline treatment methods used to decrease spasticity, and suggest clinical management strategies for the nurse working with head trauma and CVA patients who exhibit spasticity.
