Ottobock Myo Plus prosthesis control

Most people take it for granted that they can go about their everyday lives with two healthy hands.

To give this feeling back to amputees, Ottobock has developed Europe's first prosthesis control system with pattern recognition with the support of BLUE-ZONE GmbH. The control system adapts to the individual needs of the user and supports them with the challenges of everyday life.

For this purpose, the movement patterns of the forearm muscles are measured with eight electrodes and assigned to a hand movement via pattern recognition. This makes it possible to use the remaining muscle movement on the forearm stump to perform the previously familiar movements with the prosthesis.

When the patient reaches for an object, the movement pattern is recognized by the control unit and automatically transferred to the correct grip and rotation movement via pattern recognition. The control unit can be used in various Ottobock hand prostheses such as the multi-articulating bebionic hand.

BLUE-ZONE GmbH was able to support the Ottobock development team in the areas of design, embedded firmware and testing during the development of this innovative prosthesis control, thus making a valuable contribution to a comfortable control option for arm prosthesis wearers.
