The control of human balance is a complex task which is assured by uninterrupted flow of afferent signals reaching the central nervous system (CNS) from the muscle, tendon and joint proprioceptors, skin exteroceptors, and vestibular and visual inputs [2].
With the sensorimotor mechanism the tape stimulates the mechano-receptors in the skin exteroceptors and, by reflex action, induces changes in muscle tone.
