The Optimum Common Shape Technique (OCST) 1 , Symmetrical Center of Rotation Estimation (SCoRE) 2 and Symmetrical Axis of Rotation Analysis (SARA) 3 methods are based on research publications that can be obtained from Vicon on request. As the research and validation of the values produced by these methods is a continuing effort, it is recommended that OCST, SCoRE and SARA are used for investigative and research purposes. It is the responsibility of the user to review the scientific references and understand the methods. Any use of the methods as part of a clinical assessment is strictly at the discretion of the user.

Vicon Nexus 2 includes a Biomechanics Workflow area that enables you to associate specified data capture and processing steps with particular trial types, add joint range monitors for instant feedback, and quickly accept or reject the results of each step.
In the Biomechanics Workflow area, you can run (or modify and then run) the supplied Advanced Gait Workflow, or set up your own workflows:
- To help you to calculate a repeatable Hip Joint Center location using the SCoRE method, and an optimized Knee Joint Flexion Axis using the SARA method, Nexus includes an Advanced Gait Workflow. TheAdvanced Gait Workflow also incorporates a mathematical approach (known as OCST) that finds the average or common shape for selected sets of markers. The OSCT method allows non-rigid arrangements of skin-based markers to be used in SCoRE and SARA calculations where rigidity is assumed. TheAdvanced Gait Workflow steps each have an associated step description in the Biomechanics Workflow area that guides you through the process from marker placement to capture and processing. For more information, seeUsing the Advanced Gait Workflow.
- To set up your own workflow, see Using a custom biomechanics workflow, which explains how to set up and use custom workflows, and includes further information on using functional calibration and SCoRE and SARA.
In addition, a Vicon Nexus 2 video: SCoRE and SARA, is available on YouTube.
Note
As the videos were recorded using an earlier version of Nexus 2, you may notice small differences in the user interface.
