1. Definition of Myoelectric Prosthetic Hands

Myoelectric prosthetic hands are advanced artificial limbs that utilize electrical signals from the user’s muscles to control movements. These devices come in two primary types: cosmetic and functional.

2. Cosmetic Myoelectric Prosthetic Hands

Cosmetic myoelectric prosthetic hands focus on aesthetics and appearance rather than functionality. Here are some key features:

1. Appearance: Designed to closely resemble a natural hand, these devices often use skin-like materials for a lifelike look.
2. Weight and Size: Generally lighter than functional hands, making them easier to carry; however, they may not have the realistic range of motion.
3. Limited Functionality: Mostly static, allowing only basic grip functions; they lack the advanced features seen in functional versions.
4. Customization: Users can choose colors and styles to match their individual preferences, prioritizing visual appeal over utility.
5. Cost: Generally less expensive than functional prosthetics, making them an attractive option for those who prioritize appearance.

3. Functional Myoelectric Prosthetic Hands

In contrast, functional myoelectric prosthetic hands emphasize performance and utility. The following are notable characteristics:
