Advantages of externally powered prosthesis with feedback system using pseudo-cineplasty

Seiji Nambu, MD, et al.

People with upper-limb amputation require new arms. However, currently available electrical-powered prosthetic arms are difficult to use because of a lack of sensory feedback. We therefore designed a simple control and feedback system using a human- machine interface attached to a forearm tendon, based on the idea of cineplasty. We investigated the ability to determine the size of objects grasped by a robotic hand in the absence of visual information. The subject could distinguish between large and small objects with 100% accuracy and between small, medium, and large objects with 80% accuracy. This technique allows only partial sensory feedback but appears to offer several advantages over other human-machine interfaces.
