A poor suspension in a TF prosthetic could lead to which of the following issues?

A poor suspension in a transfemoral (TF) prosthetic can lead to the risk of falling due to inadequate control and stability of the prosthesis. Good suspension is crucial for ensuring that the prosthesis remains securely attached to the residual limb and that the user has proper alignment and control while walking or standing. If the suspension system is not functioning well, the prosthesis may shift or move inappropriately, which can result in a lack of support during weight-bearing activities. This instability can increase the likelihood of falls, as the user may not be able to adequately balance or maintain posture without the prosthesis functioning as intended.

Inadequate suspension might not necessarily cause excessive knee flexion, foot driving too far forward, or pain in the residual limb directly. While these issues can be influenced by various factors such as alignment and socket fit, the immediate and critical concern with poor suspension is the increased risk of falling, making this the most pertinent consequence associated with inadequate suspension in a transfemoral prosthesis.
