WP’s project INPUT
WP8: patient training.
Coordinators: Prof. Dr. C. (Corry) van der Sluis, Dr. R. (Raoul) Bongers and Dr. A. (Alessio) Murgia, University Medical Centre Groningen: Rehabilitation Medicine and Human Movement Sciences, The Netherlands.
This WP aims to develop a computer-based training game to help users to learn to control 4 DOFs in a prosthetic hand simultaneously. While the control of INPUT will be natural and intuitive in the sense that phantom limb movements will be directly matched to prosthetic movements, subjects with acquired limb amputations still require training to restore consistent phantom limb muscle activations. The current project uses a computer game to teach the user to produce appropriate myosignals such that the simultaneous proportional prosthetic control device generates the appropriate movements (i.e., grip types of the hand and other actuated joints) of the prosthetic device.
The key objectives in the current work-package are:
- Developing a computer-based rehabilitation game in which an avatar is controlled with algorithms used in controlling a prosthetic hand simultaneously and proportionally.
- Establishing optimal types of feedback for learning to control the avatar in the rehabilitation game.
- Establish whether the computer-based training game leads to better control of the prosthesis than conventionally based prosthetic training using a lab-based set of ADL tasks.
WP9: clinical tests.

The current state of practice in the prosthetic field is that a wide range of questionnaires and tests is used to evaluate different types of prosthetic device usages (Deijs et al, submitted; Van der Niet
et al, 2010; 2014). Questionnaires usually concentrate on user satisfaction or on user rates of capacity of performance with the prosthesis, while most tests focus on a specific aspect of
behavior that is evaluated. Important for the current project is that no tests exist that are explicitly developed to evaluate simultaneous proportional control of a multi-DOF hand.
The main objectives of the current work package are:
• Develop a test to measure the performance, cognitive load, and quality of movements with the
simultaneous proportional prosthetic control device
• Develop a system to monitor prosthesis activities in daily life tasks in a laboratory setting, including
the grip patterns and opening/closing of the hand, and the wrist, elbow, and shoulder angles
employed
• Test the advancements of the simultaneous prosthetic control device in comparison to
current state of the art control algorithms of multi-DOF prostheses in daily life tasks.
