Interested in a database full of IMU and EMG data? We present the RRD MyPredict database

Written by: Erik Prinsen

 

Over the past five years, Roessingh Research and Development (RRD) participated in the H2020 MyLeg project (http://www.myleg.eu), coordinated by Raffaella Carloni from the University of Groningen. Within this project, RRD was responsible for the high-level control of a to be developed powered transfemoral prosthesis. The ultimate goal of the project was to create a smart and intuitive prosthesis that was compatible with osseointegration. In adherence to the FAIR principles, all data that was gathered on individuals without an amputation have now been published as open access. We also published an open access article that describes the data which can be found here: https://www.nature.com/articles/s41597-023-02341-6. In this article we explain what we did, what the database is and where it can be found.

 

Intent recognition using EMG

Surface electromyography (sEMG) is a non-invasive technique that could provide meaningful information for human motor intent recognition. Motor intent is the determination to move or change the state one is in. For instance, when we are approaching a staircase, we adapt our steps in such a way that we position our feet perfectly to ascent the steps. This intent can be captured using the signals that command our muscles to contract, precisely what sEMG records and analyzes.

 

The need for a lot of data

There are downsides to sEMG as well. sEMG suffers from confounding factors such as muscle fatigue, electrode placement differences and intra-subject variability. This means that a control schema that utilizes sEMG could work on one day, but could yield poor results on the next day. Therefore, a lot of data is necessary to capture the variability of sEMG between subjects and between days to develop robust human motor intent recognition systems. Furthermore, detecting the change from one activity to another is harder than detecting a continuation of the activity. Therefore it is necessary to have databases that are rich in these transitions so that algorithms can be trained properly.

 

The RRD MyPredict database

In the past three years we have collected the Roessingh Research & Development-MyLeg Database for activity prediction (MyPredict), containing data from 55 subjects in 85 measurement sessions. These subjects performed all kinds of gait-related activities, including regular walking, traversing uneven terrains like grass, and climbing stairs, while transitioning freely from one activity to the next. During these measurements we collected kinematics and sEMG in various forms, using traditional bipolar sEMG as well as 64 channel multi-array sEMG.

20230725_Robert data (1)

The data it contains

We have made use of wearable measurement systems, enabling us to measure easily inside the laboratory, but also outside. In this way we have a rich dataset containing gait activities in various settings. Next to that, we have measured 10 subjects on four different days in the span of one week. These measurements enables researchers to explore the impact of time and electrode placement on intent recognition systems, a critical aspect in improving the robustness and adaptability of these systems.

 

Data validation

An essential validation step involved comparing the MyPredict database with other publicly available datasets. The results of this comparison demonstrated excellent correlation, confirming the reliability and quality of the MyPredict database. In this way we have shown that this database can be a valuable resource to the research community.

 

What it can be used for

The MyPredict database provides an opportunity for researchers to delve into sEMG data and develop and refine intent recognition systems. This comprehensive dataset offers a foundation for further studies in the field of human motor intent recognition. Researchers can explore innovative algorithms, machine learning techniques, and signal processing methodologies to unlock the full potential of sEMG data. Ultimately, it is the goal to develop practical applications that utilize sEMG signals to enrich human-machine interactions.

 

Where to find it

The database is accessible via this link: https://doi.org/10.4121/20418720. Data collection was supported by the European Union's Horizon 2020 Research and Innovation Programme grant number 780871.

STRIDER: new project to improve mobility of stroke survivors

Written by: Christiane Grünloh

 

We are excited to announce that we started a new project together with two partners: Elitac Wearables (Utrecht, The Netherlands) and cereneo foundation (Vitznau, Switzerland).

What is our goal and why is this important?

Worldwide, we have 80 million stroke survivors and every year 14 million people are experiencing a stroke. This often comes with movement impairment and a lack of balance confidence, which are addressed during the rehabilitation. We want to support this rehabilitation and the transition from in-patient rehabilitation to home by building a wearable that gives haptic feedback (for example, a vibration) to the stroke survivor while walking. This feedback will improve their gait and balance confidence already during and also after rehabilitation. We want to help stroke survivors stay confident and active also after being discharged from rehabilitation.

 

How do we do it?

As always at RRD, the people are central to everything we do. Stroke survivors are experts when it comes to living with the consequences of stroke. The design of a feedback device needs to be informed by what stroke survivors need, what works for them and what does not. Therefore, we will carry out workshops and interviews with stroke survivors both in the Netherlands and in Switzerland by our partner cereneo. In addition, we will also interview healthcare professionals, to ensure that STRIDER is well aligned with their work practices and the patient journey, going from rehabilitation centre back home. The technology will be developed in iterations, and we will test early version with stroke survivors to learn quickly, if we get it right and what needs to improve. At the end, we will carry out a study to show that STRIDER indeed improves gait and balance confidence.

 

Where are we in the project?

The project has a duration of 2 years and we started about two months ago in the beginning of May 2023. We are currently carrying out the first workshops with stroke survivors in the Netherlands and Switzerland. More workshops will follow and during the summer we will conduct interviews with stroke survivors and healthcare professionals.

Are you a stroke survivor and interested in this project? Either because you want to be informed or because you want to be interviewed by us? You can always contact us!

Moving personalised health technology forward: Understand, Create and Impact

Written by: Erik Prinsen

Roessingh Research and Development (RRD) is an impact lab for personalised health technology. Through innovative health technology, RRD contributes to prevention, self-management and optimal participation in society. For RRD, the starting point always is the end-user and the context of use to ensure that innovations meet the user needs and fit the healthcare context. How do we do it? In this blogpost we will introduce the new structure of RRD and highlight our main expertise and research focus.

 

Old wine in new bottles?

Over the past year, we have refined the focus of RRD. Where we used to focus on rehabilitation technology and eHealth as separate themes, we decided to merge these themes and focus on personalised health technology. Within personalised health technology we typically act as the social sciences and humanities (SSH) partner. Our starting point for the development, application and/or evaluation of personalised health technology is always the user and the context of use. We believe that this is essential for impactful personalised health technology and as such contributes to sustainable healthcare. To tackle these challenges, the researchers of RRD work in three flexible teams: Understand, Create and Impact. In the following sections, these teams are introduced.

Understand_NL_Understand - Copy
Create_NL_Create_Create
Impact_NL_Impact - Copy

Understanding the user and the context

Team Understand performs research to understand the user needs and requirements and the context of use as input for the development of personalised health technology. The starting point for this is our strong base of health-specific knowledge. Researchers in this team use movement analysis, patient journeys and service modelling to gain knowledge about the user’s health status and their interaction with health technology across all levels: in the persons themselves, in their daily life and in the society at large. This knowledge informs which and how health technology can contribute to the prevention, self-management and participation of its user.

 

Create tools to understand users and measure impact

To understand the user and the context of use and being able to measure the impact of personalised health technology, we need to collect data in everyday life. Team Create is working on several applications for this specific purpose. Over the years, RRD has developed its own research data platform called SenSeeAct. The SenSeeAct platform consists of the data platform itself, a web-portal and several Android and iOS applications that run on the data platform. These applications are developed in-house to give feedback to the user, therapist and/or physician. It can also be used to push questionnaires or act as a diary. Next to the SenSeeAct platform, RRD has also developed its own software for ambulant movement analysis with inertial sensors. The strength of this application is its flexibility as it can be adapted to specific use cases. In addition, researchers can have access to the raw measurement data.

 

Measuring the impact

Team Impact has extensive experience and expertise in measuring the impact of (early prototypes of) personalised health technology on its users and the society. Our expertise ranges from formative usability tests (starting level TRL-4) to GCP-compliant multicenter trials that are conducted within the scope of the Medical Device Regulation (MDR) (TRL-9). We have extensive experience in conducting randomized controlled trials. Next to this, we also have expertise in innovative research designs, such as the cohort multiple randomized controlled trial (cmRCT) that may be a better fit in the context of technology development. Besides looking at the impact of technology on its users, we also study the effect of technology on the society by using the Societal Return of Investment (SROI) methodology. With the SROI we can help organisations to understand and quantify the social, environmental and economic value that they are creating with their innovation.

 

All well that ends well

We strongly feel that the restructuring that we did over the past year has helped to shape the story of RRD in a much clearer way and prepare RRD to move towards the future. This doesn’t mean that we will stop moving forwards. We will continue to expand our expertise and knowledge through new innovation projects. Besides offering our expertise in research projects, we also offer our expertise for companies. We can perform a market analysis, give feedback to technology concepts, set-up and perform focus groups for personalised health technology, use of the research data platform for research projects, perform usability tests and perform (clinical) evaluation.

Does the profile of RRD fit with your research proposal or is the expertise of RRD a good fit in your innovation idea? Please do not hesitate to contact us as we love to share our story!

ROBERT-SAS: rehabilitating with technology after a stroke!

Written by: Cindy Rikhof

Currently, I am working for almost three years at RRD on the ROBERT-SAS project (Eurostars grant no E113693). Within this project, we investigated the recovery of the lower extremity after a stroke. Now we are running two studies within the project. The first one focuses on the clinical implementation of a robot combined with electrical stimulation, in the (sub)-acute phase after stroke. The second study focuses on the relationship between force and the sit-to-stand transfer and walking after a stroke.

A robot combined with electrical stimulation sounds fancy, but what does it look like? The picture below shows that a brace holds the leg, and the brace is connected to the arm of the robot. With this configuration, the arm can move the leg, on a pre-specified path. The grey pads on the upper part of the leg are for electrical stimulation, which causes muscle contraction and thereby movement. We started with testing in the lab. All participants were comfortable and did not find it tiring. We are currently continuing with the next step: to the clinic!

20230612_foto1_arm+leg

Clinical pilot

During this clinical pilot, we are investigating the applicability and the early effects of the robot combined with electrical stimulation. The robot is situated in the exercise room of the physiotherapy department at Roessingh, Center for Rehabilitation. We provide training in the early phase after stroke. This training consists of three times a week 30 minutes training for 3-6 weeks. During these trainings, the movements that were frequently practiced are knee extension and ankle dorsiflexion in a lying position. The training sessions are based on ‘Assist-As-Needed’, which means that for every repetition there will be determined which assistance is required to complete the movement. This assistance consists of electrical stimulation and/or mechanical assistance.
20230612_foto2_clinic

Force and sit-to-stand transfer

Does the advantage of having more force in the lower extremity also have an advantage during sit-to-stand and walking? This is the question we are interested in, in this second study. We include both early and late after stroke. The participants are asked to perform some tasks, like knee flexion and extension, ankle dorsiflexion, etc. in a lying position. During these tasks, we measure the force and the muscle activity. The next step in this study is to stand up from a chair and walk in a straight line, again we will measure the muscle activity but also the joint angles.

For this last study, we are still looking for participants! So did you have a stroke or know someone with a stroke in their history with lower extremity problems and does this study sound interesting? Please contact me via: c.rikhof@rrd.nl or +3188-0875742!

PhD defence of Jule Bessler-Etten: Safety first in rehabilitation robots!

Written by: Marian Hurmuz

The first PhD defence of 2023 took place! Jule Bessler defended her PhD thesis “Safety first in rehabilitation robots! Investigating how safety-related physical human-robot interaction can be assessed”. Nowadays, a lot of different robotic devices are (being) developed to be used in rehabilitation care. Such robots interact closely with humans. So, they introduce risks which need to be assessed carefully. But how can we assess this? And what factors do we need to take into account during the assessment? Jule worked on this topic during her PhD. On Thursday the 19th of January, 2023, she defended her PhD thesis, which you can find here.

 

Her thesis covers the following topics:

  • Identifying the most pressing risks and safety issues in rehabilitation robots.
  • Identifying factors which may lead to excessive force application to the human body by the robot.
  • Studying the proof of concept of a prototype measuring device to assess the force interplay between a human arm and a splint.
  • Assessing loads on the musculoskeletal system with an instrumented leg simulator.
  • Investigating how loads applied by rehabilitation robots affect comfort and safety.

 

Jule ends her thesis by giving recommendations for a roadmap to achieve improvements in the safety of rehabilitation robots, and to achieve knowledge and create guidelines which support developed in the safety certification process. Jule concludes her thesis that rehabilitation robots can only enter the market after this has been achieved.

We are very proud of Jule and her hard work at RRD! Jule continues working in the rehabilitation sector. She started working at Schuchmann in Germany as a Quality Assurance Manager. This company develops supporting devices for children in rehabilitation care. We wish Jule the best of luck in her career!

Involving citizens and patients in research from " how to " to " how? like this! "

Written by: Christiane Grünloh, Ria Wolkorte, Rita Schriemer

 

As soon as the calls for research arise, the topic of citizen and patient involvement comes up. Without a letter of support from a patient organization or interest group, your application has little chance. And once you have received the letter of support, how do you properly secure the involvement? Participation is not only a matter of ticking off by patients, but also of sparking researchers. Within ICMS (see description below), three colleagues from their own field are working on implementing active and meaningful involvement. Together they spread their knowledge, experience AND conviction. 

The principles of value-driven care and Shared Decision Making are self-evident in the clinic. Can we say the same of the research that precedes healthcare? Are patients, citizens or end-users involved in ICMS studies? The answer is yes. But it can be even better. If it were up to these colleagues, it will become the gold standard that members of the public, be it patients, citizens or end-users of healthcare and technology are involved in all research we do in ICMS. And not just as a participant or tester, but that they have a voice in the design and choices made in the research. Christiane Grünloh (Roessingh Research and Development), Ria Wolkorte (University of Twente) and Rita Schriemer (Sint Maartenskliniek/Radboudumc) share their point of view.

Christiane: “For the three of us, the need to get people actively involved in your research is crystal clear. It is necessary if you want to create impact. You only have impact if your research is relevant. You will achieve relevance if your research addresses the most important questions and problems of the target group. Or when the outcomes, technological or social, contribute to the quality of life.” Ria: “We involve patients in the daily practice of science. They help make decisions.” All three of them do this within their own disciplines and in ways that are customary in their field. Rita: “In clinical research we call this patient involvement. Citizen Science is the term and approach applied to health research at the UT. At Roessingh Research and Development we speak of Human Centered Design.”

Christiane: “These are different concepts and interpretations for approaches that have the same point of departure, namely that the people for whom you conduct your research are also the people with whom you conduct the research.”

 

Patient Involvement in clinical and fundamental research

Rita: “In clinical research, it is increasingly becoming the standard to actively involve patients in research. Where people were first only involved as participants, patients now also contribute within other phases of the research. This can already be done at the time of the application. Patients can contribute to the relevance of the study and comment on the layman summary. But if you start the interaction earlier, their input can lead to focus differences because certain areas are more relevant to them in daily life than others. We recently experienced this in an application for osteoarthritis research. Two highly engaged patients even attended the interview with the funding organisation. For them, the main reason for committing to the study was the research's holistic view of the disease. They know better than anyone that their condition involves a combination of medical, biological, social, movement and behavioural aspects.

Basic researchers often think that their field of expertise or research is too difficult for laymen, or that involving outsiders is of little use. Nevertheless, the PhD students on rheumatism research at the Sint Maatenskliniek and at the experimental rheumatology lab at Radboudumc all have a patient representative who follows most of the research process. They then have to explain to him or her in layman's terms what they are investigating, how they do that and what the results of the investigations are. In our experience there is a role for patients in every research phase. Patients and members of the public can contribute ideas at different levels and in different research phases. These partnerships are highly valued by both parties.”

 

Citizen Science

Citizen science is mainly known from ecological research, for example, counting birds. But this view is too limited. Citizen science has been widely applied in health research in recent years. People with a chronic condition are often already looking for solutions to make their lives more pleasant. It is precisely this motivation and self-inquiry that you can use in research. Ria: “In Twente we started working with a group of people with rheumatoid arthritis according to the principles of citizen science. Actively involving citizens in your research means a different division of roles than the traditional one between patient and researcher. With the people involved we made agreements about data management and open science. Who owns the data and who can access it? Only the researcher? Or is the data also from the participating citizen themselves. How should access be arranged? These were nice conversations with clear agreements, which do normally not take place with the participants in research.

Based on the choice of people with rheumatoid arthritis, our research theme was formulated quite loosely around fatigue. Together with the participants, whom we call co-researchers, we have further shaped this. We found that it was precisely the capriciousness and unpredictability of fatigue that they wanted to understand better. As researchers, we turned this into a research question “Which factors are associated with experienced fatigue in people with rheumatoid arthritis?”. The co-researchers then decided that it was important to take a longer-term look at the degree of fatigue and factors that can influence it. To this end, they determined the maximum number of measurement moments (namely: 1) per 24 hours, as well as the duration of the measurement (namely: 21 days). This is more limited than we as researchers had in mind, but the feasibility of the research was also important to us. However, it is not only the researcher or the citizens who decide, it is a collaborative process As researchers, we naturally continue to look at what is scientifically justified, and we remain responsible for that. But there is much more a principle of joint decision-making and transparency.”

 

Participative health technology design

To develop technology that has a high usability and creates positive user experiences, , it is important to know what needs and goals people have, what their characteristics are, what tasks they have and in what context they will use the solutions. This is the starting point for creating initial ideas for possible solutions, which are then continuously tested and improved together with the users.

Christiane: “We recently started a study about eHealth for people with COPD. One important goal for the clinical researchers is to develop a prediction model that predicts when symptoms are getting worse for the patient. To do this, patients have to collect data for a longer period, for example, with a wearable and by answering questionnaires . But by talking with patients, we learned that people also want something in return for providing their data. They also expect feedback from their personal measurements. Data collection alone is not helpful to them, but rather can be a burden, especially for patients with low energy. This is important to take into account when developing the app, because otherwise people will stop using it in the long run and then clinical researchers will not have enough data for their prediction model. We already know these kinds of comments from human-centered design, or from action research, yet I keep seeing this blind spot. For me, research without the active input of end-users and stakeholders is unconceivable. In this way, we bring together all the relevant perspectives and expertise, and learn about the needs of the different user groups, to create health technologies that are useful for all of them.”

Together we can make research more relevant and better. And beyond that, patient involvement, citizen science and human-centered design keep the conversations between science and society going.

Involving citizens, patients and end-users is not "rocket science", but it does require a certain responsibility and care from the researcher. If you have questions about this, we can aid, educate and guide you towards involvement in your design and implementation of the research. You will see that it is very rewarding and becomes self-evident. Would you like to know more about how to involve people in your research? We are happy to think along with you at an early stage!

Involving stakeholders as co-researchers: Taking a first step in how to train them

Written by: Kira Oberschmidt

 

For almost three years now, RRD has been involved in the Pharaon project (Horizon 2020, grant agreement No. 857188). In Pharaon, we use action research to integrate technologies for smart and healthy ageing. At the end of the project, RRD is going to provide guidelines for action research that can be used in other projects.

In our work, we notice that the involvement of non-researcher stakeholders (for example patients and healthcare professionals) becomes increasingly important. Especially in participatory projects that make use of approaches like action research or citizen science, simply involving these stakeholders as participants is not enough. Instead, they should take on a more active and empowered role. However, as there are not formally trained as researchers, more knowledge and preparation might be required.

We see that stakeholder skill training is occasionally mentioned in literature as a way of preparing stakeholders to become co-researchers. However, little practical information about such training is given. This left us wondering:

  • What is being taught?
  • Who are the recipients of the training?
  • When do training activities take place?
  • What are identified training needs (why do we need this training)?
  • How is the training set up and which methods are used?

 

Workshop at NordiCHI 2022

To answer these questions, we decided to invite researchers with an interest in stakeholder skill training to a workshop. This session took part on 9 October 2022, as part of the pre-conference program at NordiCHI 2022. NordiCHI is a biannual, international conference on Human-Computer Interaction This took place in Aarhus, Denmark this year. The topic of this year’s event was Participative computing for sustainable futures.

During the workshop, our group of organisers engaged in some very interesting discussions with the participants. For example we talked about:

  • How to find a common language between stakeholders?
  • How can we identify training needs?
  • Is training even the correct term for such activities?
20221026 NordiCHI (4)

While working in smaller groups we also took some time to identify barriers and facilitators of good stakeholder skill training. (We were unable to settle on a better term, so for now we kept calling it ‘training’). While there are still a lot of open questions, it was nice to see that many participants took inspiration and ideas for their own practice from the session.

Extending CE certification under the Medical Device Regulation (MDR) to a new 'intended use' - A real-world example

In recent years, Roessingh Research and Development (RRD) has worked intensively to coordinate a multi-center intervention study. This intervention consisted of a soft-robotic glove, called Carbonhand, which was developed to support hand function for patients with reduced hand pinch strength. Bioservo, the manufacturer of Carbonhand and sponsor of the study, had the intended goal of extending CE certification of the system within the MDR to a new medical application. Carbonhand already had a CE for its operation as an aid in daily tasks. However, the new "intended use" is focused on the therapeutic effect of Carbonhand, or improving hand function after long-term use of the system as an aid during daily activities. RRD was therefore asked to design and conduct a clinical evaluation that could demonstrate whether or not that therapeutic effect is there.

Carbonhand systeem

For this, RRD set up an appropriate research protocol according to the Good Clinical Practice (GCP) guideline, an international ethical and scientific quality standard (ISO14155) for the design, recording and reporting of human-related research. In addition, RRD realized the approval at the Medical Ethics Review Committee (METC), we realized cooperation with 8 Dutch (rehabilitation) centers and trained all involved in the application of the Carbonhand system and the implementation of the research protocol. A monitor from an external party was involved to check the implementation of the GCP guideline and all collected data.

 

Intensive cooperation leads to success

Within this study 63 participants were included with reduced hand squeezing strength, independent of underlying diagnosis, who used the Carbonhand during a period of 6 weeks at home while performing daily activities. Three baseline measurements took place beforehand, followed by a post-measurement (within 1 week of intervention) and a follow-up measurement (4 weeks after the end of the intervention). Despite intervention of the COVID-19 pandemic, we managed to conduct the study successfully, not least due to the intensive and pleasant cooperation with the participating centers. On Tuesday, September 27, the final measurement took place and the data collection was officially completed. Of course, we could not have reached this milestone without the commitment of the clinical centers: Roessingh Center for Rehabilitation, University Medical Center Groningen, Isala clinics, Rijndam rehabilitation center, Reade center for rehabilitation and rheumatology, Hoogstraat rehabilitation, Sint Maartenskliniek with the location Canisius Wilhelmina Hospital, Klimmendaal.

 

In the coming period we will focus on the analysis of all outcome measures. Interim results were promising, now we need to see if this remains so after analysis of all data. If you are interested in the results of the study, keep a close eye on our news page for the latest developments.

 

Do you recognize the above process as a medical device manufacturer and have a similar issue? RRD is happy to advise and support you in the design and implementation of your clinical evaluation under the MDR!

Looking back at RehabWeek 2022

It was a special RehabWeek this year. It was the first in three years because of the covid pandemic. It was also my first physical conference since covid, and the last one prior to all the lockdowns was RehabWeek 2019. So we came full circle last week. And it was 'at home', in the Netherlands. It felt somewhat like a reunion. And whether it was a psychological post-covid effect, or the longer 3-year period in between two RehabWeeks, or just that a lot of developments are happening, it felt like more news was shared than normally, there was more to catch up on with people, and more plans discussed for future collaborations. All in all, it was great to meet our colleagues again and talk about how they are doing and to hear about their latest developments. The fact that the social programme also involved water cabs and the SS Rotterdam topped it all off.

Showcasing RRD at Rehabweek

When Rotterdam was announced as the location for the next RehabWeek (2021, originally) at the previous conference in Toronto, we said we should have a good representation of RRD at this edition. Well, we kept our promise. RRD presented in 6 workshops, Hans Rietman delivered a keynote and was expert panel member, Erik Prinsen and Hans Rietman were involved in parallel programme of ISPO-NLand NSRM, we had 4 presentations in various conference sessions, RRD chaired 5 sessions, and had 3 posters on display. The poster from Robert Schulte was nominated for Best Poster Award and he pitched his research findings on smart signal processing from the MyLeg project. Additionally, Claudia Haarman presented her work in one of the ICORR sessions about GRIP, a collaboration with Anke Kottink, where Hankamp Rehab and RRD evaluated a very small and smart wearable device that supports key grasp for people with spinal cord injury, for example.

Inspirational topics

In between latest developments and research findings of rehabilitation robots, electrical stimulation, VR, eHealth applications etc., in various combinations, there were a few transdisciplinary topics that came back in many presentations and discussions. A lot was said about the need and benefits of involving end-users, either patients or therapists or other stakeholders, in early stages of technology development. Although this is definitely not news to RRD (glad to hear that we've been doing the right thing all along), it is nice to see this catching on across the RehabWeek audience. It was fitting that Stephanie Kosterink presented (twice) about using the Societal Return on Investment (SROI) method to elicit the impact of technology in a broad sense, including quality and process improvements. One of our examples for an SROI was the Innovation Lab of Roessingh Centrum voor Revalidatie, which gained a lot of interest as a means to implement rehabilitation technology in clinical practice and to gauge its impact. Another topic that stood out was the Medical Device Regulation (MDR). Its challenges was a frequent topic of discussion on the exhibition floor with developers of rehabilitation technology. Besides this, we had two presentations about it's practical implications for research with medical devices; once in relation to safety requirements for rehabrobots and using instrumented dummy limbs to solve this, once in relation to following MDR during a multi-center clinical evaluation of the effect of a soft-robotic glove (Carbonhand) used unsupervised at home. We hope our contributions gave some inspiration for how to deal with the discussed challenges.

Looking forward to the next RehabWeek, next year in Singapore!
