People often alternate between bouts of walking and running, for instance, when adults participate in recreational activities. Transitioning between activities can be challenging for prosthesis users because existing prosthetic feet are not well-suited for both tasks. Meanwhile, switching between prostheses for different tasks is often impractical.

- Walking is challenging for users of transtibial prostheses due to the lack of calf muscle function, and powered ankle prostheses help but don't fully replicate the role of calf muscles, specifically the gastrocnemius.
- A study investigated whether adding a passive elastic Artificial Gastrocnemius could reduce demands on the hip and knee joints for users walking with a powered ankle.
- Results showed that the Artificial Gastrocnemius significantly reduced hip demands in most participants, but its effects on knee demands were inconsistent, suggesting further research is needed to see if it enhances mobility and quality of life for users.
