The purpose of this project is to further improve and test the current ankle brace. The challenge is to design a comfortable slim fit ankle brace that is competitive with current ankle support braces on the market and still has the durability and strength that taping has done by professionals. The ankle brace is 3-D printed using an Ultimaker 5S and then tested with a testing rig designed to rotate a model foot as well as human participants testing their range of motion. So far, the ankle braces created in previous cycles have proven to be lightweight and limit inversion/eversion of the ankle helping prevent ankle sprains. More testing with human participants will be done and the ankle braces will change in design and size.
