 Powered prostheses can help a bugney amputees move more efficiently and comfortably than passive prosthetics. In our study, we found that powered prostheses improved weight-bearing symmetry, effort, and speed during the stand-up movement compared to passive prosthesis. Additionally, we observed improvements in all three metrics with increasing assisted torque levels commanded by the powered prosthesis. Furthermore, we saw increased weight-bearing asymmetry at the end of movement and increased kinematic asymmetry with increasing assistance from the powered prosthesis. This suggests that powered prostheses may be able to reduce the amount of effort required to complete tasks, leading to better overall performance and quality of life for those living with the bugney amputations.
