As described in step 5 of Review and finalize a calibration of a labeling skeleton using a ROM trial, to enable Plug-in Gait to calculate the static outputs based on the measured marker positions, you can run a Plug-in Gait Static pipeline on the reconstructed and labeled static frames of either a ROM trial or a static trial.
The Plug-in Gait Static pipeline is intended to calculate subject-specific offsets for use as inputs to the Plug-in Gait Dynamic pipeline. If joint angles are required, you must run the Plug-in Gait Dynamic pipeline in addition to the static pipeline, even for a stationary subject.
Process Static Plug-in Gait Model properties
The following table describes the properties you can specify for the Process Static Plug-in Gait Model pipeline operation:
|Specify the first frame to be used for processing.
|Specify the last frame to be used for processing.
|Specify the diameter of the markers used, assuming they are applied to the skin's surface. The default is 14mm.
|Anterior Thorax Tilt is Positive
|Select this option to specify that the anterior thorax tilt is positive. Clear this option to specify that the anterior thorax tilt is negative.
|Output Joint Centers
|Select this option to visualize the joint centers that are calculated by Plug-in Gait.
In this section, you can configure Plug-in Gait to assume that certain markers are at the same height from the floor during the static trial. Set the appropriate option to enable Plug-in Gait to compensate for your patient's stance during the static trial.
Important: Set the appropriate foot option if you specify the Sole Thickness Delta subject measurement because the patient is wearing shoes or orthoses that introduce a vertical difference between the toe and the heel (for details, see Subject measurements for Plug-in Gait lower body model).
|Plug-in Gait assumes that the LTOE and LHEE markers are level with one another. Select this option if the patient's left foot was flat with the toe and heel in contact with the floor, even if the left toe (LTOE) and heel (LHEE) markers were not level with one another.
|Select this option if the patient's right foot was flat with the toe and heel in contact with the floor, even if the right toe (RTOE) and heel (RHEE) markers were not level with one another.
|Select this option if the patient's head was held level during the static trial, even if the rear of head markers (LBHD,RBHD) could not be placed level with the front of head markers (LFHD, RFHD).
