AnyBody Modeling System™

Release of the AnyBody Modeling System™ Version 4
AnyBody Technology is proud to release Version 4 of the AnyBody Modeling System. Below are two descriptions of the main developments in Version 4, the muscle recruitment algorithms, and the graphical user interface including Model View.

Improved Muscle Recruitment
In biomechanics, inverse dynamics is traditionally understood at the process of computing from measured ground reaction forces in a gait analysis to net moments in the anatomical joints. However in AnyBody context, inverse dynamics is much more than that. In brief, inverse dynamics allows you to simulate muscle and joint forces in the entire body undergoing complex movements, taking dynamic inertia forces in to account, and not necessarily requiring measured forces in the interface between the body and the environment.

Key to this when working with AnyBody's sophisticated model is the muscle recruitment methodology which has been completely reworked in the new version 4.

Improved Graphics and Interface
The key feature in the new Model View is that interaction with the model appearance in the Model View is now possible. In the first release of this it allows simple manipulations without acting through drawing objects in the AnyScript code.

AnyBody is Officially Supporting C3D Format
AnyBody is now officially supporting the C3D format. C3D is "...a public domain, binary file format that is used in Biomechanics, Animation and Gait Analysis laboratories to record synchronized 3D and analog data. It is supported by all 3D major Motion Capture System manufacturers, as well as other companies in the Biomechanics, Motion Capture and Animation Industries."

New MyoScan-Z EMG Sensor

Designed for a sampling rate of 2048 samples per second, this new EMG sensor offers an unique impedance check mode, which can be triggered from BioGraph Infiniti software. It measures raw EMG signals with a range from 0 up to 2000 micro-Volts. MyoScan-Z makes impedance check fast, easy and reliable, and avoids risk of cable misplacement. It monitors skin impedance and sensor connection.

Benefits of impedance check:

  • Good contact between the electrodes and the skin is required to have a good quality signal and prevent artifacts.
  • Measuring the impedance between the electrodes is the recommended way to verify good contact. It is simple, fast and accurate.
  • It shows instantaneously which electrode is not properly connected or which part of the skin is not well prepared.

Impedance check is usually performed with an impedance meter. When you use a regular impedance meter, you have to:

  • interrupt the session
  • disconnect the cables
  • connect the meter to each site and measure them one by one
  • reconnect the cables (at the right place)
  • restart the session
  • And this, every time you need to verify the impedance!

With MyoScan-Z, you can get it done in 3 clicks:

  • pause the session
  • run the impedance check simultaneously on all the sites without disconnecting any cable
  • unpause the session
