The Flexision measuring devices use electromyography, linear magnetic acceleration and ultrasonic sensors to provide data about a person's reflexes. Early diagnosis of reflex abnormalities is important as they are often linked to certain disorders and neurological diseases. To offer highly individual and precise evaluations the results of the exam are not compared with an arbitrary central scale. Rather, the device allows to observe the changes of the reflexes from measurement to measurement. This is necessary, because the behaviour of reflexes differs significantly depending on age, health and genetics.
