compression paralysis

n.

Paralysis due to compression of a nerve, as by prolonged pressure.

compression paralysis

Etymology: L, comprimere, to press together; Gk, paralyein, to be palsied

a paralysis caused by sustained pressure on a peripheral nerve. The condition may be temporary or permanent, depending on the duration and intensity of pressure.

paralysis

loss or impairment of motor function in a part due to a lesion of the neural or muscular mechanism; also, by analogy, impairment of sensory function (sensory paralysis). Called also palsy. Motor paralysis may be expressed as flaccid, in the case of lower motor neuron lesion, or spastic, in the case of an upper motor neuron lesion. See also paraplegia, quadriplegia, hemiplegia and paralyses of individual cranial and peripheral nerves.

paralysis of accommodation

paralysis of the ciliary muscles of the eye so as to prevent accommodation.

anal paralysis

manifested by flaccidity and lack of tone of the anal sphincter, and loss of house training restraint in companion animals.

antepartum paralysis

pressure on sciatic nerves by a large fetus in late pregnancy in a cow can cause posterior paralysis that is cured by a cesarean section.
