DISORDERS OF MOTOR FUNCTION (SEE ALSO CHAPTER 82
WEAKNESS )
Goals of Treatment
Weakness or motor deficits are often a sign of a significant underlying illness.
The primary goals of treatment should be early recognition of life-threatening
conditions such as spinal shock and ascending paralysis. Treatment should then
focus on assessment of the pattern of motor deficit and anatomic localization in
order to identify the underlying etiology.
Every level of the neural axis is involved in the performance of motor tasks.
Paresis refers to partial or complete weakness of a part of the body. Various
clinical designations are used to describe patterns of weakness: paraplegia (or
paraparesis), affecting the lower half of the body; quadriplegia, affecting all
limbs; and hemiplegia, referring to weakness of one side of the body. Paraplegia
most often results from spinal cord involvement, whereas hemiparesis is most
often a sign of cortical disease.

LOCALIZING LEVEL OF NEUROMOTOR DYSFUNCTION
CLINICAL PEARLS AND PITFALLS
Anatomic localization is usually possible after evaluation of the
distribution and character of the deficit ( Table 97.8 ).
MRI of the spine is the imaging modality of choice to detect
compressive mass lesions.
