Simi Motion Inverse kinematics/dynamics

Inverse kinematics

This module enables the calculation of joint centers, joint and segment rotations as well as segment axes on the basis of certain standard marker sets (modified Helen Hayes).

The data complies with the typical data sets gained from clinical gait analyses carried out throughout the world.

Inverse dynamics

In addition to inverse kinematics data, torques, lever arms and external forces can also be calculated in combination with measurements from one or two force plates. This provides all the necessary data for a professional and detailed analysis (e.g. gait analysis).

The results can be output in graphs and reports. In addition, virtual reality displays in the form of animated skeletons and realistic 3D images can be produced. Forces and torques can be superimposed on the image if required.

The following calculations can be performed:

segment centers (local/global), joint centers (local/global), segment rotations (local/global), joint rotations (local/global), constraining forces (local/global), constraining torques (local/global), muscle torques (local/global), external forces (local/global), external torques (local/global), external levers (local/global).
