Movement analysis

Human movement analysis is a non-invasive technique that can be implemented using different devices. The aim is to measure kinematics and kinetics while providing other useful information to integrate the biomechanical picture of motor gesture. The test is objective, quantitative and multifactorial and can be used both to study the functional limitations caused by a specific condition and to improve sports performance.

Most movement analysis labs are equipped with a standard set of instruments (stereophotogrammetry system, electromyographic signal analysis system and force platforms) that allows clinicians to obtain reports containing space-time, kinematics, kinetics and muscle activation data. Each movement, however, must be studied individually to understand the biomechanical variables that describe it and that can explain its evolution and/or improvement.

Figure 1 The image schematically represents all the concepts that can be included in movement analysis.

For example, Optogait provides the opportunity to obtain multiple space-time variables that are specific to each movement. When analysing a series of jumps with counter-movement or running, flight and contact times are crucial: in the first case, it will also be important to know the height of the jumps, while in the second case, for example, cadence measurement is of primary importance.

Similarly, integrating Gyko with Optogait provides information about postural control during running and walking, while in the case of jumps it is essential to obtain the duration of the eccentric and concentric phase and the estimated RFD (Rate of Force Development).

In addition, when assessing a motor gesture, it is often important to know the motor range of the joints that allow it to be performed, and this measurement is always provided by the Gyko inertial sensor.

The combined use of these two instruments also allows joint mobility tests and static or semi-static balance tests to be conducted, which are crucial for understanding in greater depth aspects that affect the performance of any movement.

Movement analysis can be therefore considered as a large container of parameters, which can be objectively measured using a number of instruments which, together, provide a full description of any motor gesture (see Figure 1).
