3D Posture

By January 6, 2017

Instruction

3D Posture is a static assessment, so it is important that the patient remains as still as possible when capturing.

  1. Click on ‘New Assessment.’
  2. Click on ‘Posture’ option.
  3. Select: ‘Front.’
  4. Subject should stand with feet square to the camera. Place a marker on the floor or follow instructions shown below to ensure the feet and ankles are square to the camera.
  5. Instruction to Subject:
    • Stop and stand with a normal erect posture, take a deep inhale in and out and look straight forward.
  6. Once the patient has exhaled and relaxed, click the “Calibrate’ button.
  7. Click ‘Capture’ button.
  8. Press save.

How to Determine if the subject’s ankles are square to the camera:

  • The “Ankles” data needs to be “0. _ _ cm”   If the ankles are 1 cm or higher, this is an indication that one foot is placed in front or behind the other, which may give a false sense of rotation in the transverse view for the rest of the body.

Left-side of the page:

The green avatar in the left side of the screen is a representation of the data analysis of the Frontal plane. The avatar is represented in degrees and displays the lateral tilts in the body. Example: If the shoulder is 5.15 degrees R, this means that the right shoulder is 5.15 degrees lower than the left shoulder.

The data in the bottom left of the screen represents both the frontal and transverse plane data in centimeters.  In the example above, the first line of data is expressing the frontal plane data “Right shoulder is 2.67cm below left”. The second line expresses the amount of rotation between shoulders. In this example, the “Right shoulder is 3.70cm in front of left”

The rest of the data in this column will follow a similar pattern in relation to order of joints. First the frontal plane data, and then the transverse plane.

Right-side of the page:

The green avatar in the top right of the screen is a visual representation of the sagittal plane, specifically focusing on forward head carriage. This data is represented in degrees forward or ahead of the plumbline.

A visual of the transverse data is located in the right-hand side of the screen, along with color-coordinated numerical data directly below.

This assessment screen displays the postural data that is acquired using the sagittal plumb line. The plumb line originates on the posterior side of the Lateral malleolus and travels up the body in a straight line. This line and data will become visible once the patient has turned so their left side of the body is facing the camera.
