A Prosthetic Myoelectric Hand uses electrical signals generated by muscles (myoelectric signals) in the residual limb to control movement. These devices aim to restore functionality and improve the quality of life for individuals with upper limb loss or congenital limb differences.

Functions

Actions of fingers are controlled by myoelectricity

Wrist joint can rotate passively and self-lock at any position.

Suitable for middle and short stumps of arm.

Key Features

Myoelectric Control: Electrodes placed on the skin detect muscle activity when the user contracts specific muscles.

Multiple Grip Patterns: Modern models offer various grip types (pinch, tripod, power grip, etc.) for different tasks.

Individual Finger Movement: Some advanced hands allow independent finger control for more natural and precise movements.

Rechargeable Batteries: Most are powered by compact lithium-ion batteries.

Custom Fit: Typically integrated into a socket that's molded to fit the user's limb.
