Which of the following is an advantage of a passive prosthesis?

• A. No harnessing or control cables
• B. Requires harness and cables
• C. Very heavy
• D. Limited cosmetic restoration

Answer: (A)

Passive prostheses are non-powered devices that do not use harnesses or control cables to operate. The main advantage is that you don’t have to don or manage any harnessing or cables, which makes the prosthesis easier to wear, lighter in daily use, and more comfortable. This simplicity is especially helpful when the goal is cosmetic appearance or a stable limb for balance rather than active grasping or movement. The other statements describe features that aren’t advantages of a passive prosthesis: needing harnesses and cables, being very heavy, or offering only limited cosmetic restoration do not reflect the typical benefits of a passive design.
