Posture Analysis

Postural analysis is frequently used to evaluate the stability and balance of a quiet standing subject.

Gyko, placed on the trunk or at the level of the centre of mass, provides important information about the body sway of the subject and through appropriate protocols it enables evaluating the relative contribution made by the various components of the postural system (visual, proprioceptive of different origin, labyrinthine, etc.).

Gyko lets you simply and quickly obtain the best known indexes concerning the projection of the body's centre of gravity on the ground.

The main indexes returned are:

  • Projection length and area.
  • Projection travel speed.
  • Sway frequency

In this case the graphic is a "projection" showing all the movements (the red dot indicates the position at the end of the test) and an overlay of the ellipse. To the right there are two graphs, one for the antero-posterior movements and the other for the medio-lateral movements with the time being the abscissa and the movement in mm the ordinate.


The test can be done with a custom "SwayTest" without the OptoGait bars.

There is also a predefined "Body Sway" protocol that consists of two static (Sway) tests in which the patient must stand as motionless as possible for 30 seconds, in the first test with eyes open and in the second one with eyes closed.

There is no need for the OptoGait bars, but only the Gyko inertial sensor.

At the end of the protocol you can view a report that gives all the data comparing the eyes open test with the eyes closed test.
