Biomechanics workflow

The new methodology included in Vicon Nexus 2 uses the dynamic movement around a subject’s joints to minimize errors and significantly improve the estimation of joint centers and joint axes. This approach is known as functional calibration.

Nexus 2 introduces a full functional calibration workflow, in which the SCoRE and SARA methods and algorithms, patented by the Julius Wollf Institute for Biomechanics and Musculoskeletal Regeneration, at the University of Berlin, can be included.

The biomechanics workflow offers two key components:

❙     You can now create and save subject calibration pipeline steps (a workflow).

❙     Real-time visual calibration feedback provides you with an instant and reliable indication that enough subject joint calibration frames have been collected for a successful calibration.

The biomechanics workflow system largely replaces the functions of the Nexus 1.x Protocols by enabling you to save a series of live and/or offline steps (a workflow) for both collecting and processing data.

Real-time subject monitors (joint range overlay monitors)

To allow real-time monitoring of subject calibration (particularly functional calibrations), Nexus 2 includes a new monitor type. These new joint range monitors enable you to monitor any kinematic subject joint in real-time during a range of motion trial (ROM) or single joint calibration.

The new monitors are also valuable in non-calibration trials, for example, sports performance trials.

For more information, see View real-time subject calibration feedback with monitors.

Auto Initialize Labeling pipeline for fast calibration

The new Auto Initialize Labeling pipeline can, in many circumstances, eliminate the need for the manual labeling step that was previously required for static trials, and enables you to run functional subject calibration.
