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. The MotionMonitor, in combination with LIBERTY, provides the best set of tools for a quick and flexible setup, data collection and data analysis.


Product Integration

Polhemus 6 Degree-Of-Freedom (6DOF) motion capture 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, varioususer-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. Once 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 formulae 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.

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 LIBERTY system is a strong component to the solution. LIBERTY is particularly valuable when time is of the essence, and researchers or clinicians need a system by which they can set-up their respective subjects or patients in minimal time. The LIBERTY system tracks all 6 degrees-of-freedom, which eliminates the set-up of multiple markers per body segment
 
IST and Polhemus have built a strong relationship enabling the ability to provide a turn-key motion tracking solution to meet the various needs of many applications for data acquisition and analysis.
