Question 1

What is the most critical functional milestone that predicts community ambulation success for lower limb prosthetic users?

Accepted Answer

Independent donning and doffing of the prosthesis

Answer

Independent donning and doffing ensures patients can use the prosthesis reliably without caregiver dependence, which is foundational to community ambulation.

Question 2

Upper extremity prosthesis training typically progresses in which order?

Accepted Answer

Controls training → use training → activity-specific training

Answer

Prosthetic training follows a hierarchy: first mastering control of the terminal device, then integrating use into daily tasks, then applying skills to specific activities.

Question 3

Which condition is considered the most common secondary musculoskeletal complication in long-term unilateral transtibial amputees?

Accepted Answer

Contralateral knee osteoarthritis from asymmetric loading

Answer

Long-term asymmetric gait loads the contralateral knee with increased compressive forces, significantly elevating osteoarthritis risk in the intact limb.

Question 4

Osseointegration as a prosthetic attachment method provides which key functional benefit over socket-based suspension?

Accepted Answer

Direct skeletal attachment eliminating skin-socket interface and improving proprioception

Answer

Osseointegration transmits mechanical stimuli directly to the skeleton, significantly improving proprioceptive feedback and eliminating socket-related skin issues.

Question 5

Targeted Muscle Reinnervation (TMR) is performed to primarily:

Accepted Answer

Reduce neuroma pain and improve myoelectric prosthesis control signals

Answer

TMR reroutes residual nerves to nearby motor nerve branches, reducing painful neuromas and creating additional EMG signals for advanced myoelectric prosthetic control.
