The handedness or corporal hemi dominancy is a key factor to understand the motor skills because knowing corporality is in the intersection with knowing the spatial variables in which all motor action are developed. In spite of the existence of a good number of tests to value the handedness of the diverse corporal zones, we considered that they don\u2019t pay sufficient attention towards the corporal zones of postural support and the corporal zones of gestural precision that take part in the use of the corporal hemi dominancy. Both act simultaneously: the one of postural support it allows the static and blockade of the movement that permits the corporal zone of gestural precision executes the dynamics of the motor action. This distinction, key in motor learning, usually is not well considered and is exactly what it allows us to obtain the effectiveness in the execution of a great fan of sport skills as far as the profiles of integral handedness, no integral and ambidextrous. We have designed the LATMO tool of registration that designates a set of tests or complementary tests used with views to evaluate several aspects or the handedness of a subject.<\/p>\n\n
