Hand with sensory feedback.

On sensory feedback in hand prostheses

Amputation of the hand implies the loss of the ability to grasp and the ability to "feel". The grasping function can be primitively restored using an active prosthesis. Multi­articulating electrically powered hands have recently made their way to the market and these hands provide enhanced grasping and gripping capabilities. However, these hands provide no direct and conscious sensory feedback ...

Ideas on sensory feedback in hand prostheses.

Latin America can be divided into four parts. Bordering with the United States is Mexico, next there is Central America then the Northern and Southern parts of South America. Europeans tend to be concentrated in the South where there are many Germans, British, French, Italians and Danes. The further North you travel the more you meet the Indians and their culture and the more you encounter diff...

Experience with a hand grasp neuroprosthesis incorporating natural sensory feedback

This paper presents experience with a hand grasp neuroprosthesis that is controlled by means of signals from natural sensors in the skin. The signals from the natural sensors were recorded with a cuff electrode implanted around the palmar digital nerve innervating the radial aspect of the index finger. The implanted muscle stimulator is part of the commercial FREEHAND® System. A data-recording ...

Restoring natural sensory feedback in real-time bidirectional hand prostheses.

Hand loss is a highly disabling event that markedly affects the quality of life. To achieve a close to natural replacement for the lost hand, the user should be provided with the rich sensations that we naturally perceive when grasping or manipulating an object. Ideal bidirectional hand prostheses should involve both a reliable decoding of the user's intentions and the delivery of nearly "natur...
