Myo Plus TR

Johanna lives in Stockholm, has worked as a journalist for a long time and has now recently completed her Master of Law. Due to cancer, she had to have her right hand amputated. Independence and being able to keep up with her children are quite important to Johanna. Myo Plus and her bebionic hand support her in this.

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.

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.

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.

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

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.

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.
