Spastic Paralysis is a term used to describe a condition where people experience spasms
that can be accompanied by muscle stiffness. Spasms are spontaneous, uncontrolled,
exaggerated muscle contractions that can result in uncontrolled jerky movement. In spastic
paralysis the nerves controlling muscle movement are hyperirritable and do not function in
a coordinated manner, so that impulses from them cause spasmodic muscle contraction.
Spinal cord injury, such as that produced by inflammatory diseases of nerve tissue, can
injure motor neuron fibers in the spine and cause spastic paralysis. Congenital spastic
paralysis, or cerebral palsy, is often a result of intrauterine disease or birth injury,
or occasionally some inherited nervous system defect.
