Answer

Spasticity is defined generally as the velocity dependent resistance of a muscle to passive range of motion. It is a common finding after middle cerebral artery (MCA) stroke and, if not proactively managed, can lead to serious complications, including contracture, pain, and skin breakdown. Contracture describes a fixed loss of range of motion of a joint and can occur from joint pathology, skin contracture after major burns, or, in the case of untreated spasticity, permanently shortened muscle.
