5.1.3.1 GYKO
If the test was performed using the Gyko inertial sensor as well (usually at the height of the shoulder
blade), there are the following in addition to the previous values:
Area [cm
2
]: The Area parameter provides a dimension of how much the subject moves his/her
trunk. The greater it is and the broader are the antero-posterior and medio-lateral rotations. In
numerical terms it represents the area of the ellipse of confidence (95%), which is the ellipse
that contains approximately 95% of the points of the trajectory.
Ant/Post [mm]: Antero-posterior displacement (positive values = anterior, negative ones =
posterior)
LH/RH [mm]: Medio-lateral displacement (positive values = to the right, negative ones = to the
left)
Control strategy: AP, ML or NEUTRAL depending on the values mentioned above (AP if the axis
of the Ant/Post ellipsoid is greater than the medio-lateral one; ML, vice versa. If the axes are
equal the strategy is called "neutral")
