What is a simple option for increasing the ease of pre-positioning the prosthetic elbow in flexion for a TH amputee with a body powered prosthesis?

Having a forearm lift tab located distally/anterior provides a straightforward and effective solution for a transfemoral (TH) amputee using a body-powered prosthesis. This design promotes easier manipulation of the prosthetic elbow into a flexed position by allowing the user to leverage gravity and body mechanics more effectively during positioning. When the lift tab is placed distally, it enables the user to apply upward force on the forearm, assisting in achieving the desired flexion without requiring excessive strength or complex movements.

The placement of the lift tab in an anterior position further enhances ergonomics, making it more intuitive for users to engage with the prosthesis. This ergonomic design can help reduce fatigue and improve the overall user experience by facilitating smoother transitions and better control over elbow positioning.

In contrast, while an elbow strap may provide some stability, it does not directly aid in the ease of positioning the elbow in flexion. A more complex locking mechanism could complicate the process, potentially leading to frustration for the user. Removing the elbow locking feature might allow for more freedom of movement but may also compromise control and stability, which are crucial for function in daily activities.
