N2 - Spinal Tuberculosis could cause abnormalities in the lower extremity, even after the surgery and can be treated with Ankle-Foot Orthoses (AFO). The patient with that condition has to stabilize their body because it tends to fall forward. Thus, a ventral AFO is needed to support them. This study aims to evaluate AFO design by using Finite Element Method (FEM) with two different thickness (2 and 4 mm). The material used was a Polyethylene Terephthalate (PET). Three subphases in the stance phase were simulated, namely initial contact, midstance, and terminal stance. The external force in the simulation was based on the patient’s weight (50 kg). The result showed that the highest stress was obtained from ventral AFO with a thickness of 2 mm at the terminal stance, 244.7 MPa. This value exceeded the Ultimate Tensile Strength (UTS) of PET which indicates the design would break. The ventral AFO with a thickness of 4 mm had lower stress than the UTS of PET. The strain of both designs was quite low with the maximum value of 0.019 from the ventral AFO with a thickness of 4 mm in the terminal stance. The deformation was also acceptable for both designs with the highest value of 39.67 mm from the ventral AFO with a thickness of 2 mm in the midstance. In conclusion, the ventral AFO with a thickness of 4 mm could be used for post-surgery spinal tuberculosis patient’s rehabilitation.
