Question Answer
Why can lateral bending occur? Prosthetic: Short, improper shape of lateral wall, aligned in ABD. Amputee: Poor balance, ABD contracutre, ADB weakness on residual limb, hypersensitivity.
Why can an ADB gait occur? Prosthetic: Too long, improper shape of lateral wall, aligned in ABD, excessive knee friction. Amputee: ADB contracture, pain in residual limb, weak hip flexors or ABD.
Why can circumduction occur? Prosthetic: Too long, excessive knee friction, socket is too small, excessive plantar flexion. Amputee: ABD contracture, weak hip flexors, lack of confidence, pain in residual limb, unable to initiate knee flexion.
Why can excessive knee flexion occur during the stance phase of gait? Prosthetic: Socket set forward, foot set in excessive dorsiflexion, too long. Amputee: Knee/hip flexion contracture, pain in residual limb, decreased quad strength.
Why can vaulting occur? Prosthetic: Too long, inadequate socket, foot in excessive plantar flexion. Amputee: Discomfort, fear of using prosthetic, short residual limb, pain.
Why can rotation of the forefoot occur at heel strike of gait? Prosthetic: Loose fitting socket. Amputee: Poor muscle control, weak medial rotators, short residual limb.
Why can trunk flexion occur during gait? Prosthetic: Socket is too big or knee instability Amputee: Hip flexion contracture, weak hip extensors, inability to initiate knee flexion
Why can medial/lateral whip occur during gait? Prosthetic: Excessive rotation of the knee, tight socket, improper alignment of prosthetic. Amputee: Weak hip rotators or knee instability
