In medicine,paresis (/pəˈriːsɪs,ˈpærəsɪs/), compound word from GreekAncient Greek:πάρεσις, (πᾰρᾰ- “beside” + ἵημι “let go, release”), is a condition typified by a weakness of voluntary movement, or by partial loss of voluntary movement or by impaired movement. When used without qualifiers, it usually refers to the limbs, but it can also be used to describe the muscles of theeyes (ophthalmoparesis), thestomach (gastroparesis), and also thevocal cords (vocal cord paresis).
Neurologists use the termparesis to describe weakness, andplegia to describeparalysis in which all voluntary movement is lost. The termparesis comes from theAncient Greek:πάρεσις 'letting go' from παρίημι 'to let go, to let fall'.
