Simpler motions, typically benefit from the use of a Cardan sequence, however, more complex joints like the shoulder may require the use of an Euler sequence. In this chapter, we highlight the need for and use of Euler sequences to calculate joint angles. However, these concepts can be applied to other parameters as well.
Throughout many calculations in biomechanics – and therefore Visual3d – the Cardan sequence has a significant impact on the results. In this chapter, we explain what a Cardan sequence is, and how it impacts your data when calculating, for example, a joint angle.
Many types of calculations in biomechanics involve kinematics in some respect. The motion between two segments is the foundation for many calculations such as joint angles and joint moments. For this reason, it is essential to understand how coordinate systems are defined and how to tweak them to describe exactly what you are trying to measure.

As two segments rotate with respect to each other, the more complex the motion, the more challenging it is to describe mathematically. In biomechanics, defining the rotations is key to understanding the meaning of the data. One method is to use Cardan Sequences; however, in this tutorial, we explain what Euler Sequences are, and how they are used to calculate rotaions between segments.
Performing 3D calculations between segments is mathematically complex. When those segments are also moving, setting up those calculations is critical to understanding what your data means. One of the methods in Visual3D to obtain rotational data is to use Cardan Sequences. In this tutorial, we show you how to use Cardan Sequences in Compute Model Based Data and how the data changes based on your choices. We also show you the use of Euler Sequences, which in Visual3D are listed in the Cardan Sequence menu.
Calculating rotational data between two objects in space can be mathematically challenging, especially if those bodies are moving with respect to each other. In biomechanics, we regularly need to perform calculations between segments, and one of the ways we do that is by using Cardan Sequences. In this tutorial, we explain what they are.
Joint moment is one of the most common biomechanical values to be calculated and be used for evaluation of a subject’s performance or condition. In this tutorial, we focus on how the data is calculated depending on which resolution coordinate system or Cardan sequence is used.
