Myo Plus TR
Even after a forearm amputation or with a congenital malformation, a mental image of the hand usually remains mapped in the brain. Amputees can still imagine closing, opening or rotating their hand. This activates the remaining muscles in the residual limb.
Even after a forearm amputation or with a congenital malformation, a mental image of the hand usually remains mapped in the brain. Amputees can still imagine closing, opening or rotating their hand. This activates the remaining muscles in the residual limb.
These muscle signals are transformed into myoelectric signals using electrodes on the forearm and translated directly into a movement of the prosthetic hand. Myo Plus learns to interpret the user’s individual movement patterns, assigning each to a specific prosthesis movement. These patterns can be adapted with the Myo Plus app.
This intuitive control enables users to fully utilise the potential of their highly complex, multi-articulating prosthetic hands. Myo Plus pattern recognition is optimised for the bebionic hand and the MyoBock system.

Myo Plus makes it possible to utilise the prosthesis control functions in a unique and entirely natural manner. It therefore allows the user to intuitively utilise their remaining capabilities.
Compared to conventional myoelectric systems, no switching signals, such as CoCo or OpenOpen, are required to switch to a desired grip or function. This allows you to concentrate fully on your activities.
Myo Plus allows the user to continuously adapt their prosthesis control device to their individual needs by adding additional grip types to the bebionic hand.
The Myo Plus app lets you easily use and configure your hand prosthesis. It serves as a “window into the prosthesis” and visualizes muscle activities in the residual limb through the spiderplot.
Aside from the bebionic hand, the Myo Plus prosthesis control device is compatible with other analogue and MyoBock terminal devices such as the Electric Greifer. This allows users to choose a solution that is optimally adapted to their activities.
Myo Plus is flexible and learns the individual commands directly from the user. It can be improved at any time by independently adding further recordings in everyday life.
Wolfgang uses Myo Plus pattern recognition
Wolfgang is a farmer in Germany who lost his right hand in an accident at work. The idea of not wearing a prosthesis was out of the question. Wolfgang therefore uses Myo Plus pattern recognition and switches between his bebionic hand, the VariPlus Speed hand or the System Electric Greifer depending on the situation.
Lina with the bebionic hand
At 17, Lina had her right hand and parts of her forearm amputated as a result of a tumour. At first she was shocked, but thanks to the early care she received from her orthopaedic technician, she quickly regained her courage.
Myo Plus pattern recognition
Movements carried out by myoelectric prostheses are generated by muscle activity in the residual limb. Unlike a conventional two-channel control device, Myo Plus uses the individual muscle activity (known as movement patterns) that occurs in the residual forearm during different hand movements. Myo Plus learns these movement patterns through a recording process via an app. A certain prosthetic hand grip can be assigned to each learned pattern. The control device thus first learns from the user.
Myo Plus app
The Myo Plus App is the central interface between user and prosthesis control.
- Visualization of individual movement patterns via the spider plot
- Adapt control by recording additional patterns in everyday life and expand it with additional grips
- Track which prosthesis movement has just been detected
- Fine-tune parameters and turn functions on or off
- Available free of charge in the Apple or Google Store
Phantom hand imagination
After an amputation, there is still a certain imagination of the hand - also called phantom hand. The movements that can be performed mentally are called phantom hand movements. These generate muscle signals in the forearm that are interpreted by Myo Plus.
The better the phantom hand imagination, the more reliably the prosthesis can be controlled and the greater the choice of possible grip types.

Testing with the Myo Plus Cuff
The Myo Cuff and the Myo Plus App make it easy and flexible to evaluate and train. The Myo Cuff already includes all necessary components and can optionally be connected to a demo prosthesis to allow a realistic experience of different hand prosthesis types and their functionalities.
