Spastic Paralysis

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.
 

Causes of spastic paralysis

Spinal cord injury, such as that produced by inflammatory diseases of nerve tissue, can injure motor neuron fibers in the spine can 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.
