What is the prosthetic cause associated with forward flexion deviation?

When considering the prosthetic cause associated with forward flexion deviation, having a short walker explains this phenomenon effectively. A walker that is too short can lead to impaired stability, making it difficult for the wearer to maintain an upright posture during ambulation. As a result, the individual may unintentionally lean forward, causing a forward flexion deviation in the prosthetic limb.

In contrast, the other options relate to different issues that may not directly lead to a forward flexion deviation. For instance, a low anterior wall in a prosthetic socket could fail to provide adequate support at the anterior section, but it typically influences stability rather than causing a specific forward flexion movement. Similarly, weak extensors might cause general instability and a tendency to lean forward but do not pinpoint the prosthetic cause of forward flexion deviation itself. An abduction contracture impacts the alignment of the leg and may influence gait mechanics, but it does not directly relate to how the length of the walker affects posture.
