Which of the following is a disadvantage of a myoelectric prosthesis?

• A. Increased cost
• B. Improved sensory feedback
• C. Minimal maintenance
• D. Proprioceptive feedback

Answer: (A)

The key point being tested is the drawback tied to using a myoelectric prosthesis, which centers on cost. These devices rely on sensors, processors, and rechargeable batteries to translate muscle signals into movement, plus the need for regular charging, upkeep, and potential repairs. All of this adds up to a higher upfront price and ongoing expenses, making cost the main disadvantage you’d encounter with a myoelectric prosthesis.

The other options describe advantages or characteristics that aren’t drawbacks: improved sensory feedback would be a benefit, not a disadvantage; minimal maintenance isn’t accurate because these devices require regular care and charging; and proprioceptive feedback isn’t typically considered a feature or disadvantage in this context.
