Transradial prostheses: Trends in development of hardware and control systems

Area of Science:

• Biomedical Engineering
• Rehabilitation Technology

Background:

• Trans-radial prostheses are wearable devices designed to restore function and appearance for individuals with limb differences.
• These artificial limbs, comprising an artificial wrist and hand, aim to enable daily living activities with minimal assistance.

Purpose of the Study:

• This review paper provides an overview of the hardware systems in state-of-the-art trans-radial prostheses.
• It focuses on the latest technologies in mechanical systems, including terminal devices, artificial wrists, and body attachments.

Main Methods:

• A review of current literature on trans-radial prosthesis hardware.
• Analysis of hardware designs for terminal devices, prosthetic wrists, and body attachments.
• Exploration of the latest trends and future directions in prosthesis design.

Main Results:

• Latest hardware designs for terminal devices emphasize grasping motion, a primary function.
• Review includes hardware designs for prosthetic wrists and body attachments.
• Current developments are increasingly mimicking human upper limb form and function.

Conclusions:

• Key factors in trans-radial prosthesis development include size, shape, weight, durability, appearance, and functionality.
• Despite advancements, the availability of these high-tech devices is limited due to complexity and cost.
• Further research and development are necessary to enhance the accessibility and capabilities of trans-radial prostheses.
