268 Gyko is an inertial measurement tool for the analysis of the movement of any body segment. It contains the latest generation components that are used for making accurate and repeatable measurements of acceleration, angular velocity, and magnetic field in three dimensions. • 3D accelerometer, to measure the linear accelerations to which the device is subjected (up to 16G). • 3D gyroscope, to measure the angular velocities of the device (up to 2,000°/s with an acquisition frequency of 1000Hz. • 3D magnetometer, to measure the magnetic field to which the device is subjected. The Bluetooth data transmission provides real-time measurements directly to the PC via the Microgate software that, with its scientifically validated algorithms, offers simplified data processing and interpretation. Data can also be acquired without a PC, using a MicroSD memory card, thanks to its long lasting battery. From the measured data, it is possible to describe the kinematics of the body segment to which Gyko is fastened so as to provide the user with summary information about the quality of the analysed movement. Gyko can be used in two ways: In combination with OptoGait Gyko acts as a optional accessory to your existing OptoGait equipment to provide additional data such as body sway and posture analysis during: • Walking and running tests both on a treadmill and with one- or two-dimensional linear systems. • Marching in place tests. • Vertical jumping tests. • The (new) tests for posture analysis. Gyko, placed in the area beneath the shoulder blade by using a special bib with a comfortable 3-button fastening, enables integrating the information measured on the ground with the kinematics of the trunk in order to provide accurate information on the stability and coordination of the upper body. The movement of the trunk is analysed in each phase of the step, and through advanced algorithms, specific parameters of the analysed test are estimated such as: • Antero-posterior and medio-lateral imbalance. • Main directions and breadth of the movement of the trunk. • Dominant control strategy (AP, ML or neutral). Advanced parameters such as the following are available: • Upper Phase Coordination Index (UPCI) that describes coordination in the rotation of the trunk. • Phase difference between the lower body and the upper body. • RMS, harmonic ratio e-harmonicity index describing gait stability.
