A patient fitted with an upper-limb body-powered prosthesis complains of insufficient terminal device grip force. Which adjustment would MOST directly increase grip force?
Answer: Add a stronger rubber band or spring to the terminal device
The grip force of a voluntary-opening terminal device is determined by the number and strength of the rubber bands or springs; adding stronger ones increases closing force.
During vacuum-assisted socket suspension (VASS) fitting, the technician notices the pump fails to maintain vacuum levels between steps. What is the FIRST thing to check?
Answer: Integrity of the suspension sleeve and liner seal
Vacuum loss is almost always caused by an air leak at the suspension sleeve or liner interface; checking and replacing these components resolves most pump-failure complaints.
Which carving relief is required on the posterior wall of a transtibial socket to accommodate the popliteal soft tissue during knee flexion?
Answer: Popliteal relief
The popliteal relief is carved into the posterior-proximal socket wall to prevent impingement on the soft tissue behind the knee during flexion.
When performing dynamic alignment for a transtibial prosthesis, which gait deviation suggests the socket is too far anterior relative to the foot?
Answer: Early heel rise
When the socket is positioned too far anterior, the patient must plantarflex the prosthetic foot early to maintain balance, causing premature heel rise.
According to standard prosthetic protocols, how often should a patient with a mature, stable residual limb have their prosthesis formally evaluated by a credentialed clinician?
Answer: Every 6 months to 1 year
Standard of care guidelines recommend formal prosthetic evaluations every 6 to 12 months for patients with stable residual limbs to ensure continued fit, function, and safety.
A transtibial socket exhibits a medial brim that is too high, causing discomfort at the medial tibial flare. What is the correct corrective action?
Answer: Trim the medial brim to the appropriate height
Trimming the medial brim lowers it away from the medial tibial flare, eliminating direct pressure on this anatomically sensitive area.
Which of the following best describes the purpose of the ischial containment design in a transfemoral socket?
Answer: To contain the ischium and medial femoral tissues, improving rotational and mediolateral control
Ischial containment sockets capture the ischium and surrounding soft tissue inside the socket brim, providing enhanced mediolateral stability and rotational control compared to ischial seat designs.
