Case Study: Biomechanics Analysis—IST Integrates Polhemus LIBERTY
Innovative Sports Training (IST), based in Chicago, IL, provides complete solutions for 6 Degree-Of-Freedom (6DOF) motion capture and integrated comprehensive analysis. The MotionMonitor, IST's software package, integrated with Polhemus LIBERTY, the fastest, most accurate, scalable electromagnetic motion tracker available, creates the finest advanced data acquisition and analysis system in the market place. Combined, this provides a perfect set of tools for a quick and flexible setup, data collection and data analysis.
Once the LIBERTY is set-up, sensors (up to 16 available per LIBERTY system) are assigned to body segments. Various protocols can be used for tracking anatomical landmarks and defining local coordinate systems for each body segment. Once the subject/patient is setup, various user-defined parameters can be assigned to control the manner in which the activity is recorded, i.e. using event markers and triggers to start or end data collection such that all activities are synchronized to one specific event.
After data has been recorded, the activity along with graphical
displays of data can be played back immediately. All standard kinematic
and kinetic data can be selected from drop-down menu items. In addition,
the user can calculate data with the user-defined data formula using
any raw or processed data variable. Smoothing parameters such as a
Butterworth filter can be applied uniquely to each sensor or data
acquisition channel. Further enhanced functionalities for data reduction
and exporting are also available.
Other hardware systems such as EMG, force plates, event markers, digital video, haptic devices, immersive displays and eye-tracking can be integrated as well for synchronous data collection and analysis along with the sensor data.
Why LIBERTY is the Professional's Choice
LIBERTY offers a quick and easy subject set-up and is a more economical system over traditional optical video systems. When line-of-sight could be an issue, the Polhemus LIBERTY system is a strong component to the solution.
