The correct answer is a loss of voluntary muscle control even though the spinal motor muscles are intact.
Spastic paralysis refers to a prolonged pathological situation in which the muscles are influenced by continuous spasms and overstated tendon reflexes due to destruction of the central nervous system.
The condition is a side effect of paralysis, which fluctuates from mild or extreme muscle stiffness, uncontrollable leg motions. It may take place in combination with multiple sclerosis, spinal cord injury, brain trauma, or cerebral palsy.
