Spastic paresis. By permission from Sack W, Wensing CJG, Dyce KM, Textbook of Veterinary Anatomy, Saunders, 2002

• hypocalcemic p. — a stage or form of hypocalcemia in which the patient remains ambulatory.
• inherited spastic p. — an inherited defect of cattle that appears several months after birth. A hindleg is stiff and straight on rising and the hoof does not reach the ground. After several minutes the gastrocnemius muscle relaxes and the animal walks normally although the leg is still abnormally straight. Gradually the stiffness worsens until the animal is unable to walk. Called also Elso heel.
• parturient p. — see periparturient hypocalcemia.
• progressive canine p. — see dural ossification, degenerative myelopathy of German shepherd dogs.

A progressive psychosis associated with neurosyphilis.

• Defects and Disabilities - paresis: muscular weakness and mental deterioration, less severe than paralysis, due to neurological disease, esp. syphilitic infection

This article is about the physical malady. For the mental disorder, see general paresis of the insane.

Not to be confused with Paruresis

Paresis is a condition typified by partial loss of voluntary movement or by impaired movement. When used without qualifiers, it usually refers to the limbs, but it also can be used to describe the muscles of the eyes (ophthalmoparesis), the stomach (gastroparesis), and also the vocal cords (Vocal cord paresis). Neurologists use the term paresis to describe weakness, and plegia to describe paralysis in which all voluntary movement is lost. The term paresis comes from the Ancient Greek: πάρεσις "letting go" or "paralysis" from παρίημι "to let go, to let fall."

• Hemiparesis — One arm and one leg on either side of the body
• Tetraparesis — All four limbs

Other

• Gastroparesis -- Impaired stomach emptying
• It is also used to describe a form of ophthalmoplegia.
• In the past, the term was most commonly used to refer to "General paresis," which was a symptom of untreated syphilis.^[1] However, due to improvements in treatment of syphilis, it is now rarely used in this context.
