F. Matthias Alexander developed an ability that avoided what negative bodily issue?
Alexander Technique The Alexander Technique (A.T.), named after Frederick Matthias Alexander, is an educational process that attempts to develop the ability to avoid unnecessary muscular tension by retraining physical movement reactions. Alexander believed the individual's spatial self-awareness was related to psychological conditioning; questionably trained foundation habits of posture can be unsuitably added into procedural skills. Alexander observed that those whose goals justified it necessary to have trained themselves to overcompensate could not trust their judgment of physical orientation and required effort, (their "sensory appreciation.").
Paresis Paresis ( ) is a condition typified by a weakness of voluntary movement, or 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 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" from παρίημι "to let go, to let fall".
