During fabrication, an AFO’s joint axis must be aligned with the anatomical ankle axis to ensure that the AFO provides the desired function. However, sometimes, the two axes aren’t properly aligned, and the AFO fails to achieve the desired outcome. In an attempt to gain greater insight into the consequences of misalignment, a program called AFO3D was developed to simulate the likely result of both rotational and translational misalignments.
The following assumptions apply to the simulation:
AFO3D Simulation of AFO Joint Misalignment Program
We have created an AFO3D-Installation Folder located outside this web page. The Folder contains: 1) the AFO3D Installer (an executable file); 2) the AFO 3D Installation Instructions; and 3) the AFO3D User's Manual. Everyone is welcome to access, view, download and use this program. Prior to leaving this web page, you may preview the AFO 3D Installation Instructions and the AFO 3D User's Manual or download from the off-site AFO 3D Installation Folder. Access the AFO 3D Installation Instructions for information and screen shots about the installation and extraction of the included MatLab compiler.
The program consists of two main windows: a command window where the simulation is setup and run, and a Plot Window where the results of the simulation are displayed. Open the AFO 3D-Installation Folder to access all resources.
- Download the AFO3D_install program to your computer (Windows 7 compatible).
- Double click the icon to open a black DOS prompt window and the program will download the MatLab Compiler.
- Continue to follow the prompts for the MRTC installer.
- After installation, click on the AFO3D icon to open and run the AFO3D app.
