WearRAcon Conference - 26 October

02.30 pm - 03.00 pm

Dr. Maziar Ahmad Sharbafi,
TU DARMSTADT

Abstract:
To support human movement in their daily tasks, we need to understand how humans perceive assistance. Including users in the design and control procedure could improve the seamless integration of assistive systems for natural locomotion. I will present novel bioinspired concepts in the design and control of lower limb exosuit. These concepts can be extended to other sorts of assistive systems too.

02.30 pm - 03.00 pm

Frank Krause, TNO

Co-Speaker: Dr. Aijse de Vries, TNO

Abstract:
The potential of exoskeletons to assist workers in practice depends on the level of exoskeleton support and the proportion of time that such support is provided.  Exoskleton-specific posture-torque relationships and posture profiles obtained in practice form the basis for a quantitative method to assess the exoskeleton potential in specific work settings.

Co-Speaker: Dr. Jason Gillette,
Iowa State University

Abstract:
We will describe and demonstrate the Shoulder Injury Risk Assessment (SIRA) app for objectively quantifying shoulder fatigue. Data are being collected with and without shoulder exoskeletons in the field with ‘real world’ tasks and in the lab simulating standing assembly, seated assembly, and stocking shelves. Initial results will be presented comparing the accuracy of AI-based to lab motion analysis and validating the predictive model with EMG data relative to the ACGIH fatigue threshold limit value (TLV). We seek to enable safety professionals to evaluate shoulder MSD risk in the workplace and provide an assessment of whether an exoskeleton may be a potential solution for injury mitigation.

Dr. Kai Heinrich,
Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA)

Abstract:
The literature shows that the biomechanical principle of action of shoulder-supporting exoskeletons has been demonstrated in many cross-sectional studies under controlled conditions in the laboratory. However, the proof of the biomechanical principle of action of exoskeletons does not yet allow conclusions to be drawn about sustainable effectiveness in terms of a reduction in musculoskeletal complaints. Therefore, in a six-month prospective field study, we investigated the effectiveness of exoskeletons with regard to the prevention of musculoskeletal disorders (preventive effectiveness) under real workplace conditions in the relevant user group.

03.30 pm - 04.00 pm

Prof. Lorenzo Masia,
Heidelberg University

Abstract:
Soft wearable exosuits have been introduced in the last decade as possible candidates to overcome the limitations from devices using rigid structures: the exoskeletons.
Despite the exosuits initially promised tangible improvements, yet their soft wearable architecture presents strong drawbacks, placing this technology more in a complementary position rather than on a higher step of the podium respect to their predecessors. During my speech I will introduce the progress from our research on soft wearable exosuits for assistance and augmentation, by presenting novel solutions on mechanical design, novel implementation of control strategies based on machine learning and artificial vision to master the exosuits´ non-linear behaviours, improving flexibility and controlling such devices symbiotically.  I will discuss in detail how using bio-signals by means of realtime techniques based on musculoskeletal dynamics can be used to provide a symbiotic interface between the exosuit and the user and introduce also our latest results in clinical applications and performance augmentation.

03.30 pm - 04.00 pm

Jean-Jacques Atain Kouadio, INRS

Co-Speaker: Dr. Liên Wioland, INRS

Abstract:
It is proposed to present a feedback of the process of acquisition and integration of exoskeletons in real working situation (luggage handlers  at  an international airport). The whole process started 2 years ago.  A focus will be made on the integration phase which lasted one year and during which the users tested several models of exoskeletons. The evaluation tools used during this phase will be presented. The results will mainly concern the implementation of a longitudinal follow-up of the dynamic of acceptance and familiarization with these new technologies.

04.20 pm -  04.50 pm

Dr. Petra Abele,
Social Insurance for Agriculture, Forestry and Horticulture

Abstract:
The presentation will give an outlook regarding the usage of exoskeletons in the agriculture, forestry and horticulture sectors to promote healthy work conditions, including use-cases and results of preliminary studies. It will also highlight demands and challenges specific to these sectors.

04.20 pm -  04.35 pm

Sönke Herbst, N-Ippin GmbH

Abstract:
Exoskeleton is the generic term - the correct selection, assigned to the application / user cases, is decisive for acceptance by the employees. We would like to provide information on this in the lecture.

Carina Güttler, Pflegepraxiszentrum Nürnberg

Abstract:
In the course of several tests (n=317) conducted in a nursing care setting, 102 participants rated exoskeletons positively, especially with regard to the degree of relief and occupational safety. A pilot study (n=33) shows no measurable effects in terms of muscular activity of the lower back, however the subjective perceived parameters of the subjects indicate a significant difference when wearing and transferring with a passive exoskeleton. In order to be able to make further scientifically statements about the efficient and use of exoskeletons in the nursing sector, further studies are required, in a cross-sectionally and longitudinal design.

04.35 pm -  04.50 pm

Co-Speaker: Jonas Dülberg, Auxsys GmbH

Abstract
We will showcase our latest developments in the field of active exoskeletons. We will present and discuss testing methods and results of active exoskeletons in a variety of tasks and environments.

Abstract:

Exoskeletons in skilled trades are transforming workplaces, boosting productivity and reducing strain-related injuries. They augment human capabilities, allowing workers to work in challenging positions, stand for extended periods, or prevent injuries. Used in construction, exoskeletons offer ergonomic solutions and improved safety standards. As technology evolves, they're expected to become integral tools in diverse trades.

Co-Speaker: Dr. Bérenger Le Tellier,

Abstract:
The fight against musculoskeletal disorders (MSDs) is a major concern for healthcare professionals as they represent the majority of occupational diseases. The evolution of technologies, such as physical assistance devices aimed at reducing physical strain, has the potential to mitigate pathological effects. However, the current challenge with these physical assistance devices lies in their novelty, resulting in a lack of long-term feedback and difficulty in proving their actual benefits, especially in professional settings.
Therefore, this study aims to highlight the benefits of the HAPO exoskeleton from ErgoSanté in a real work environment outside the laboratory. Such an environment presents numerous constraints that need to be considered, making the task complex. Three work tasks from Air France's Wheels and Tires
workshop were analyzed to establish an evaluation method for assessing the value of the HAPO exoskeleton. The study is divided into two parts: objective results focusing on posture and cardiac cost, and subjective results based on questionnaires addressing multiple dimensions.
The results demonstrate improvements in trunk posture and a reduction in cardiac fatigue with the use of the HAPO exoskeleton. Additionally, the questionnaires reveal overall satisfaction with wearing the exoskeleton, except for the heat generated by the device.

Abstract:
Benchmarking exoskeletons and providing performance data in an accessible and understandable format to potential users is a key element in facilitating exoskeleton adaptation. Multiple initiatives worldwide are working on establishing performance standards to simplify understanding and comparison of the different available solutions. To contribute to this effort, in this talk, we want to share some insights into the Auxivo exoskeleton evaluation framework that we use for evidence-based product development and communication.
