Introduction: Falling causes long term disability and can even lead to death. Most falls occur during gait. Therefore improving gait stability might be beneficial for people at risk of falling. Recently arm swing has been shown to influence gait stability. However at present it remains unknown which mode of arm swing creates the most stable gait. Aim: To examine how different modes of arm swing affect gait stability. Method: Ten healthy young male subjects volunteered for this study. All subjects walked with four different arm swing instructions at seven different gait speeds. The Xsens motion capture suit was used to capture gait kinematics. Basic gait parameters, variability and stability measures were calculated. Results: We found an increased stability in the medio-lateral direction with excessive arm swing in comparison to normal arm swing at all gait speeds. Moreover, excessive arm swing increased stability in the anterior–posterior and vertical direction at low gait speeds. Ipsilateral and inphase arm swing did not differ compared to a normal arm swing. Discussion: Excessive arm swing is a promising gait manipulation to improve local dynamic stability. For excessive arm swing in the ML direction there appears to be converging evidence. The effect of excessive arm swing on more clinically relevant groups like the more fall prone elderly or stroke survivors is worth further investigating. Conclusion: Excessive arm swing significantly increases local dynamic stability of human gait.

Background: Impaired upper extremity function due to muscle paresis or paralysis has a major impact on independent living and quality of life (QoL). Assistive technology (AT) for upper extremity function (i.e. dynamic arm supports and robotic arms) can increase a client’s independence. Previous studies revealed that clients often use AT not to their full potential, due to suboptimal provision of these devices in usual care. Objective: To optimize the process of providing AT for impaired upper extremity function and to evaluate its (cost-)effectiveness compared with care as usual. Methods: Development of a protocol to guide the AT provision process in an optimized way according to generic Dutch guidelines; a quasi-experimental study with non-randomized, consecutive inclusion of a control group (n = 48) receiving care as usual and of an intervention group (optimized provision process) (n = 48); and a cost-effectiveness and cost-utility analysis from societal perspective will be performed. The primary outcome is clients’ satisfaction with the AT and related services, measured with the Quebec User Evaluation of Satisfaction with AT (Dutch version; D-QUEST). Secondary outcomes comprise complaints of the upper extremity, restrictions in activities, QoL, medical consumption and societal cost. Measurements are taken at baseline and at 3, 6 and 9 months follow-up.

In wheelchair rugby (WR) athletes with tetraplegia, wheelchair performance may be impaired due to (partial) loss of innervation of upper extremity and trunk muscles, and low blood pressure (BP). The objective was to assess the effects of electrical stimulation (ES)-induced co-contraction of trunk muscles on trunk stability, arm force/power, BP, and WR performance.

In recent years, organizations across Europe, and the Netherlands in particular, have increasingly supported efforts to enhance the sustainability of festivals such as the European Climate Pact, launched by the European Commission as part of the European Green Deal, European Festivals Association and Green Deals Circular Festivals in the Netherlands (European Union [EU], 2025). As a result, festivals across Europe are growing their environmental stewardship and serving as prototypes for wider societal transitions towards sustainability (Calvano, 2024; Irimiás et; al., 2024). However, festival organizers and other stakeholders still face challenges in developing effective communication strategies that truly activate more sustainable behaviour among festival goers (Harms et. al., 2023). Generic, one-size-fits-all approaches are often applied, yet they tend to have limited impact. This is also due to the diverse nature of music festivals, ranging from indoor to outdoor settings, single-day events to multi-day experiences, and from urban to rural locations, all of which shape the audience, context, and communication needs in unique ways (Tölkes & Butzmann, 2018; Dodds et. al., 2020). Essentially, festivals are ideal for informing, experiencing and activating sustainable behavioural change through effective communication before, during and after festivals. It is therefore crucial that a more targeted approach is utilized where messages can be tailored to make communication more effective (Temmerman & Veeckman, 2024). To address pressing sustainable and social challenges within the festival sector, NHL Stenden (NHLS) will collaborate with ESNS and Thansk on a design research project. In partnership with a network of festival organizers, industry professionals, and experts, the project will explore effective communication strategies for sustainability. The goal is to develop an actionable, research-informed roadmap that supports music festivals in enhancing their sustainability communication tailored to the sector’s dynamic and diverse nature.
The Hereon team has expressed interest in the use of the PO platform for the virtualization of the (hydro)dynamic behavior of offshore wind farms, in particular regarding turbidity around wind turbines. BUas has developed the Procedural Ocean (PO) platform. The platform uses procedural content generation (AI) for data-driven 3D virtualization of complex marine and maritime environments, with elements such as geo-environment (bathymery, etc.), geo-physics (weather conditions, waves), wind farms, aquaculture, shipping, ecology, and more. The virtual and immersive environment in the game engine Unreal supports advanced (game-like) user interaction for policy-oriented learning (marine spatial planning), ocean management, and decision making. We therefore propose a joint pilot Research and Development (R&D) project to explore, demonstrate and validate how a gridded dataset provided by Hereon can show the dynmics around wind farm monopiles. Furthermore, we can explore interactivity with the engineering and design of the turbine and the multiplication of the turbine design to compose a wind farm.
