Who developed
the RYSEN?

Our pioneering partners and key contributors to the RYSEN’s leading role in rehabilitation robotics.

GTX Medical

Due to extensive know-how in rehabilitation robotics and medical device development, GTX project-led the RYSEN’s development. The company drove the mechanical design and usability engineering, alongside setting up the RYSEN’s real-time control framework and contributing to its electronic design.

 

“The RYSEN shows high value and flexibility during the rehabilitation of people with a spinal cord injury. It can act both as bodyweight support whilst simultaneously activating fall prevention. It is great to see its versatility as it can be applied to a wide range of locomotor training tasks like balance, obstacles or stairs training. As such, the RYSEN will be an essential tool during the rehabilitation of the new and promising Targeted Epidural Spinal Stimulation (TESS) therapy of Prof. Courtine and GTX medical.”

Sjaak Deckers
CEO, GTX, Switzerland

 

“With the RYSEN, we managed to move from the classical robotic approaches towards a safe, energy-efficient and high-performance bodyweight support system. The extensive usability work which was conducted in close collaboration with clinicians resulted in an intuitive device that can be smoothly integrated into existing rehab therapies.”

TU Delft

Heike Vallery’s research group at TU Delft contributed to the sensing, control, and technical evaluation of the system. They also developed a special winch design to reduce power consumption. Their key contributor, Michiel Plooij, successfully bridged the gap between academia (TU Delft) and industry (Motek) by working on both sides during the project.

 

“The RYSEN enables all sorts of challenging 3D activities in a safe environment, whilst avoiding restrictions to therapists’ physical contact with their clients. At TU Delft, we look forward to exploring, together with clinicians, the many options the system offers in applying forces to an individual.”

Principal Investigator, TU Delft, The Netherlands

 

“The RYSEN facilitates gait training and research while freeing therapists from heightened physical labor. In the RYSEN, patients can feel free, while getting support when needed.”

CRR Suva

The Clinique Romande de Réadaptation (CRR) is a tertiary center of rehabilitation that belongs to the Swiss Accident Insurance Fund (Suva), the main injury insurance in Switzerland. As field partner, the CRR was the proud sponsor of the feasibility study, performed in order to obtain the CE certification of the RYSEN.

 

“The RYSEN provides all the advantages of body weight support or microgravity for rehabilitation. Moreover, thanks to sophisticated algorithms, the RYSEN allows promotion of early overground walking training that is known to stimulate neurological recovery through improved balance, strength and proprioception.”

Chef du Service de Recherche, CRR Suva, Switzerland

EPFL

The Swiss Polytechnique Fédérale de Lausanne developed the first suspension systems for rodents, and later demonstrated the critical importance of multidirectional bodyweight support to facilitate walking in humans. Based on these findings, the institution contributed in-depth robotic knowledge and scientific input to the RYSEN progression from the first prototype to CE-certification. Furthermore, EPFL ran the clinical study with the partner hospital, the CRR in Sion, Switzerland.

 

“As a bodyweight support that now also allows unconstrained walking within a large workspace, the RYSEN has solved many of the technical issues that limited the functionality of previous systems. The user interface is intuitive and the possibility to adjust the forces in multiple directions provides unprecedented opportunities for gait rehabilitation and research.”

Gregoire Courtine, PhD
Neuroscientist, Swiss Federal Institute of Technology, Switzerland

 

“Thanks to the close collaboration of a large network of scientific, clinical and industrial partners during the development, the RYSEN is a safe, user-friendly support system applicable to adult and pediatric patients with different neuromotor disabilities.”

Motek

Almost 20 years of global experience in developing and manufacturing high-quality rehabilitation technologies has meant that Motek not only played a fundamental role in co-developing the RYSEN, but now also builds, distributes and services the product to maximize its benefits to researchers, clinicians, and patients.

 

“We are very proud to extend our product portfolio with the newest, next-generation 3D bodyweight support: the RYSEN. Developed together with scientists and clinicians in the field, its highly innovative design will open new doors for research and treatment which we will walk through together with our partners and customers. We look forward to a present and future of new rehabilitation techniques with the RYSEN.”

Frans Steenbrink, PhD
Executive Manager, Motek, The Netherlands
Head of Clinical Applications & Research, Motek, The Netherlands

 

“When we started to work on this project we set out to develop the world’s most advanced body weight support system for rehabilitation: in creating the RYSEN, we have fulfilled our ambition. This ground-breaking rehabilitation technology paves the way for a future of motion capture, virtual reality, serious games, and real-time control of unloading forces.”
