Within RRD, we work on robotics to support rehabilitation medicine, such as robots for gait training and robotic devices to support arms and hands. We use our expertise in the area of motion analysis and the measurement of muscle activation to produce smart devices that correct or support the movements and position of the limbs when necessary.
One such example is our work on robots that assist people with spasticity or partial paralysis during gait training. Another is robotics that can support the arm and hand of elderly people to independently carry out daily activities.
Supporting technology
The technology used as assistive and training devices is becoming increasingly complex, while using such devices will eventually become commonplace. At RRD we investigate how a patient functions with and without these devices. This allows us to determine the optimum balance between technical possibilities, the clinical context, and the requirements and wishes of patients and therapists. This means that we sometimes conclude that a person would be better off with less advanced technology.
Our added value in this area is that we study the influence of various orthoses, prostheses and robotic systems on the patient’s movement. For example, in our own labs we can measure muscle activation in patients with and without support from an orthosis. In addition, we can analyse the movements of limbs with the help of video recordings, 3D motion analysis systems and ambulatory sensors. Our guiding principle is always to apply advanced technology as effectively and simply as possible for both the patient and the therapist. These applications also extend beyond the treatment centre to the patient’s home.
Projects
MyLeg – Development of an intuitive prosthetic leg
The MyLeg project (Horizon 2020 project) develops a powered prosthetic leg that can be intuitively operated and trusted as a reliable counterpart during use in daily life. The aim is to improve the quality of life in people with an amputation. The myoelectric (EMG) control is the responsibility of RRD.

COVR – break down barriers collaborative robot safety
In a pan-European strategic effort to break down barriers around collaborative robot safety, five Research and Technology organizations across Europe have teamed up in a new initiative funded by the EU called COVR.

eNHANCE – Improving and training arm and hand function
The eNHANCE project (Horizon 2020 project) is focusing on the development and testing of new concepts with regard to improving and training arm and hand function during daily life in individuals with physical disabilities. It includes a multimodal interface, user assessment and personalised support.
ironHand – Soft-robotic glove
Through the development of a soft-robotic glove (the ironHand), which gives support during the performance of daily activities, elderly and patients with diminished hand function not only experience support in force, but also de opportunity to train their hand function.
Evolutions – Timing of foot ortheses
Patients who experience drop foot as a consequence of a stroke are given an orthosis that positions the foot in the correct posture. However, what point in the treatment is the most adequate to provide such an orthosis? RRD performed comparative patient research to determine this.

Gerdienke is a human movement scientist, with a PhD in the evaluation of robotic devices for rehabilitation of the arm after stroke. As senior researcher, she currently leads the research topic on therapeutic rehabilitation technology (Active Therapeutic Devices), involving supervision of 4 PhD students. She coordinates and supervises multiple European and national projects, in particular regarding clinical evaluation, collaborating extensively with care organisations, technical universities and companies. Her research is focused on applying technology for improvement of arm and hand functionality in clinical practice or at home, evaluating its impact and understanding associated neurological and biomechanical working mechanisms.

Erik is a clinical health scientist and physiotherapist. His PhD project focused on the influence of a microprocessor-controlled prosthetic knee on gait adaptations after a transfemoral amputation or knee disarticulation. He obtained his PhD on December 8th 2016 at the University of Twente. He is currently setting up studies to evaluate the added value of assistive technology. In addition, he co-organizes and participates in multiple gait analysis courses that are given by Roessingh Research and Development. His research interests mainly include assistive rehabilitation technology and clinical gait analysis. Besides his work for RRD he is also the chairman of the Dutch Society for Rehabilitation Physiotherapists.
