A patient reports that their endoskeletal (modular) pylon feels very rigid and transmits too much shock during ambulation on hard floors. Which change is MOST appropriate?
Answer: Install a shock-absorbing pylon component
A shock-absorbing pylon component absorbs vertical impact forces, reducing the shock transmitted to the residual limb on hard surfaces.
Which of the following best describes total contact socket design philosophy in prosthetics?
Answer: Distributing pressure evenly over the entire residual limb surface
Total contact socket design distributes forces across the entire residual limb surface to minimize peak pressures at any single point and improve circulation.
A pediatric patient with a unilateral transhumeral amputation is being fitted for a body-powered prosthesis. Which control motion is typically harnessed to operate the terminal device?
Answer: Biscapular abduction (forward flexion of the intact shoulder)
Biscapular abduction — forward shoulder flexion — is the primary control motion used to operate the terminal device via the figure-9 or figure-8 harness system.
When applying a roll-on silicone liner prior to donning a prosthesis, what is the correct technique?
Answer: Roll the liner onto the limb from distal to proximal, expelling air
Rolling the liner from distal to proximal expels trapped air and ensures full contact between the liner and the residual limb skin.
A patient with a partial foot amputation through the Lisfranc joint is most likely to experience which functional problem without a prosthetic intervention?
Answer: Equinus deformity and loss of push-off
Lisfranc-level amputations remove the forefoot lever arm and disrupt push-off mechanics, often leading to an equinus deformity as the calf muscles become unopposed.
In microprocessor-controlled prosthetic knees, what sensor input is MOST commonly used to detect stumble and initiate a stumble recovery response?
Answer: Inertial measurement unit (IMU) detecting unexpected angular velocity
IMU sensors detect unexpected angular velocity of the shank during early swing, triggering the microprocessor to increase resistance and prevent a fall.
Which clinical measurement is used to determine the appropriate knee center height for a transfemoral prosthesis?
Answer: Distance from the medial tibial plateau to the ground on the sound side
The sound-side medial tibial plateau-to-floor measurement establishes the appropriate knee center height to achieve symmetric knee levels in the finished prosthesis.
