Improved performance of externally powered myoelectric hands is possible when the direct control of the digit flexion and grip force are given over to an electronic controller which frees the operator to concentrate on other demands.
Design: A commercial myoelectric hand was modified to take the new touch and slip sensors and novel control method. Subject: An adult male with a traumatic mid-forearm amputation.
Outcome measure: The range and ease of use of the prosthetics system.
Result: The hand was easily and usefully operated in the home and work environment.
Conclusion: Hierarchical control of a hand is possible using sensory feedback to a sophisticated electronic controller. Such a control method reduces the demands on the user's concentration and enhances the hand's range.
