A steppage gait (high stepping) pattern is most commonly caused by:
Answer: Dorsiflexor weakness (foot drop)
Steppage gait results from dorsiflexor weakness (foot drop), requiring the patient to excessively flex the hip and knee during swing to clear the toes from the ground.
For a transfemoral amputee, which of the following socket designs provides the most total surface contact?
Answer: Ischial containment (CAT-CAM) socket
The ischial containment (CAT-CAM) socket encases the ischial tuberosity and provides total surface contact throughout the socket, improving mediolateral stability and comfort for transfemoral amputees.
Crouch gait in a child with cerebral palsy is characterized by excessive:
Answer: Hip flexion, knee flexion, and ankle dorsiflexion throughout stance
Crouch gait involves excessive hip flexion, knee flexion, and ankle dorsiflexion throughout stance, resulting in a bent-knee walking pattern with high energy demands.
Which outcome measure assesses functional mobility in prosthetic users by predicting K-level functional classification?
Answer: Amputee Mobility Predictor (AMP)
The Amputee Mobility Predictor (AMP) is specifically designed for prosthetic users, assessing balance, transfers, and ambulation across varied surfaces to predict K-level functional classification.
A patient with a transtibial amputation complains of skin breakdown on the distal end of the residual limb. The most likely prosthetic cause is:
Answer: Piston action (socket too loose with inadequate suspension)
Piston action from a loose socket or inadequate suspension causes the residual limb to move up and down inside the socket, creating shear forces on the distal end and causing skin breakdown.
During normal gait, the double support phase (both feet on the ground) constitutes approximately what percentage of the gait cycle?
Answer: 20%
Double support constitutes approximately 20% of the normal gait cycle (two periods of approximately 10% each, at loading response and pre-swing). Running eliminates double support entirely.
