Additional Measurements


Electroculogram Activity (EOG), is measured by electrodes placed on the skin near the eye.  These electrical changes are unique to each of four different types of eye movement (saccades, VOR, pursuit, and vergence).  The IX-BIO4/IX-BIO8/iWire-BIO4/iWire-BIO8, are DC coupled, allowing the measurement of EOG’s.

Strength and Performance Testing

Strength and performance testing and evaluation in athletes of all types can be performed with the iWorx EMG system. The IX-BIO4 and the IX-BIO8 offer a portable, color coded system, with the ability to generate reports and export data.



LabScribe software is a powerful recording and analysis software package offered by iWorx. LabScribe has an intuitive, user-friendly interface for setting up acquisition screens, calibrating signals and analyzing data. Up to 128 channels of data can be displayed simultaneously at sampling rates as high as 100,000 samples/second.

A comprehensive set of analysis routines have been preconfigured making data analysis and interpretation quick and easy. LabScribe includes a scripting function for use if the built-in analysis tools fall short of what is required for your application. Scripting languages currently supported include: Dadisp, Python, MatLab, LabView, and C++

In addition, data from iWorx Recorders can be acquired with LabView or Matlab or C++ programs using the provided iWorx API.
