Purpose: This study was planned to compare the effect of three different prosthetic feet on gait, weight bearing on amputated side, and ambulation activities. Material and methods: 20 unilateral below-knee amputees were evaluated for gait, ambulation activities, weight bearing on the amputated side, and comfort with SACH, dynamic and conventional prosthetic feet. Results: There was not statistically significant difference in step width, amputated and sound side step lengths (p> 0.05). Walking velocity and cadence was found to be significantly different between SACH and dynamic, dynamic and conventional prosthetic feet (p< 0.05). When ambulation activities and weight bearing on amputated side were evaluated, an important difference was found between SACH and dynamic feet (p< 0.05). Climbing up and down the stairs and ascending descending an incline showed significant differences between SACH and conventional feet (p< 0.05). Patients were more comfortable with dynamic and conventional feet. Conclusion: Consequently it can be seen that dynamic feet is the best option for amputees in terms of gait, ambulation activities, and comfort among the prosthetic feet covered through with health insurance.
