Center of pressure is a key historically reported parameter in biomechanics. In this tutorial, we show you how to use the Compute Model Based Data function to calculate the center of pressure path and how to tweak the pipeline command in order to get exactly what you want from your data.
Joint kinematics are a staple element of motion capture biomechanics reporting. In this tutorial, we show you how to use the Compute Model Based Data function to calculate joint velocity and acceleration.
For a full understanding your data, how to perform calculations, and knowing what they mean, it is fundamental to know what the Visual3D default joint angle conventions are. In this tutorial we give an overview of the conventions for the lower body.
Calculating the joint angle is a key contribution to biomechanics by the Compute Model Based Data feature. However, the rotation between two segments is very complex, and a simple joint angle calculation may not be sufficient to describe the motion. In this tutorial, we show you how to use the joint rotation fuction.
The complexity of joint angle calculations is made all the more challenging when the joint in question is the ankle. In this tutorial, we discuss why the ankle is complex, and some of the methods to calculate it with reasonable results.
The joint angle calculation in Visual3D is a feature of Compute Model Based Data. In this tutorial, we show you how to use both joint angle and helical angle functions to calculate the angle between two segments.
Throughout biomechanics literature, you will find a variety of ways to calculate joint kinematics. One of the most widely accepted is put forward by the ISB and is called the Joint Coordinate System. In this video, we explain the basics of what a joint coordinate system is, and how it can be defined.
Scientifically validated biomechanical data is essential for confidence in your results. One of the most basic – but critical – calculations to be performed is that of the joint angle. In this tutorial, we discuss the theory behind how Visual3D processes your marker data to obtain the angle between two segments.
