The initial questions to ask when evaluating motor deficits concern the site of the lesion and the type of the paralysis. The distinction between spastic and flaccid paralysis (Table 18) permits the physician to determine the location of the lesion:
  1. 1.

    Paralysis of the corticospinal neurons spastic paralysis ) due to lesions in the cerebral cortex, the subcortical white matter, the internal capsule, or the spinal cord (i.e., pyramidal system including extrapyramidal inhibitory fibers)

  2. 2.

    Paralysis of the lower motor neurons (flaccid paralysis) due to damage of the peripheral neuron, defects in transmission at the neuromuscular junction, or injury of the muscle.
