The study examines the manufacturing process of two types of ankle-foot orthoses (AFO): an adjustable joint and a modified static joint. Polypropylene and steel are used in manufacturing. Vacuum forming is used in the manufacturing process. The ankle orthosis test is performed on a patient with an ankle fracture as a result of a sports injury. The treadmill and F-Socket are used in the second step of the study for gait analysis. In addition, walking cycle results including: ground reaction force (GRF), center of pressure, pressure distribution, stride length, and footprint analysis were used to demonstrate a significant difference between healthy subjects and subjects with pathology who wore AFO. Interference, force, and pressure between feet with AFO contact areas were measured for all subjects.
