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.").
Sense of balance Sense of balance or equilibrioception is one of the physiological senses related to balance. It helps prevent humans and animals from falling over when standing or moving. Balance is the result of a number of body systems working together: the eyes (visual system), ears (vestibular system) and the body's sense of where it is in space (proprioception) ideally need to be intact. The vestibular system, the region of the inner ear where three semicircular canals converge, works with the visual system to keep objects in focus when the head is moving. This is called the vestibulo-ocular reflex (VOR). The balance system works with the visual and skeletal systems (the muscles and joints and their sensors) to maintain orientation or balance. Visual signals sent to the brain about the body's position in relation to its surroundings are processed by the brain and compared to information from the vestibular, visual and skeletal systems.
