Background: Falls in people 65 years and older evaluated in the emergency department are increasing. Of all unintentional injury-related deaths among older people, 55% are due to falls. The impact of falls, especially concerning Dutch older people with the highest proportion of living independently worldwide, is unclear. Objective: To identify the influence of age, gender, health conditions, and type of fall on the severity of injury, hospital length of stay, mortality, and discharge destination. Methods: A total number of 6,084 patients from a comprehensive regional trauma care system, 65 years and older and hospitalized after a fall, were included. Groups were compared for patient-related factors and multivariable logistic regression analysis to explore the consequences. Results: Mean age was 82 years (SD = 8.3), and 70% were female. Most falls (66.4%) were due to "slipping and tripping" or "falls on the same level," 57.4% had Injury Severity Scores between 9 and 12, and 43.3% were discharged home. Higher age and type of fall increased the likelihood of severe injuries. Men experienced shorter hospital stays than women and were less frequently discharged home. Mortality was higher in males (10.8%) than in females (6.7%) and increased with the American Society of Anesthesiologists scores for preexisting health conditions. Conclusion: Advanced age, gender, type of fall, and prior health status play a significant role in the severity of injuries, length of hospital stay, 30-day mortality, and higher discharge destination to care homes in older people hospitalized after a fall.

Background Fall prevention programs have been proven effective in reducing falls and fall-related injuries in specific target groups and settings. However, implementing these programs on a larger scale often requires adjustments for feasibility. This study assessed the effectiveness of a nationally implemented fall prevention intervention compared to usual care in community-dwelling older adults. Methods This single-blinded, multicentre randomized controlled trial included 264 community-dwelling non- and pre-frail adults, aged 65 years or older with an increased fall risk. The intervention group participated in the In Balance intervention and the control group received general physical activity recommendations. Primary outcomes were the number of falls and fall-related injuries over 12 months. Secondary outcomes included the Timed Up and Go and Four Stage Balance Test, and the 36-Item Short Form Health Survey. We imputed missing data by multiple imputation, and analysed outcomes using generalized linear- and linear mixed-effects models. Analyses were done for the total group and stratified for frailty status. Results The mean number of falls per person over 12 months was not statistically different between the intervention and control group (respectively 1.67 (SE 0.24) and 1.98 (0.37); incidence rate ratio 0.85 (95% CI 0.51-1.43)), nor the mean number of fall-related injuries (respectively 0.70 (SE 0.11) and 0.97 (0.18); incidence rate ratio 0.73 (95% CI 0.44-1.19)). Secondary outcomes also showed no significant differences between group, frailty status and over time. Conclusions Although the number of falls and fall-related injuries was lower among In Balance participants, and balance, mobility, physical function, and emotional well-being improved, these differences were not statistically significant. Impact statement The implemented In Balance program appears to be less effective than a priori assumed, possibly due to insufficient adherence to the program in practice.

Background: There are indications that older adults who suffer from poor balance have an increased risk for adverse health outcomes, such as falls and disability. Monitoring the development of balance over time enables early detection of balance decline, which can identify older adults who could benefit from interventions aimed at prevention of these adverse outcomes. An innovative and easy-to-use device that can be used by older adults for home-based monitoring of balance is a modified bathroom scale. Objective: The objective of this paper is to study the relationship between balance scores obtained with a modified bathroom scale and falls and disability in a sample of older adults. Methods: For this 6-month follow-up study, participants were recruited via physiotherapists working in a nursing home, geriatricians, exercise classes, and at an event about health for older adults. Inclusion criteria were being aged 65 years or older, being able to stand on a bathroom scale independently, and able to provide informed consent. A total of 41 nursing home patients and 139 community-dwelling older adults stepped onto the modified bathroom scale three consecutive times at baseline to measure their balance. Their mean balance scores on a scale from 0 to 16 were calculated—higher scores indicated better balance. Questionnaires were used to study falls and disability at baseline and after 6 months of follow-up. The cross-sectional relationship between balance and falls and disability at baseline was studied using t tests and Spearman rank correlations. Univariate and multivariate logistic regression analyses were conducted to study the relationship between balance measured at baseline and falls and disability development after 6 months of follow-up.

Horse riding falls under the “Sport for Life” disciplines, where a long-term equestrian development can provide a clear pathway of developmental stages to help individuals, inclusive of those with a disability, to pursue their goals in sport and physical activity, providing long-term health benefits. However, the biomechanical interaction between horse and (disabled) rider is not wholly understood, leaving challenges and opportunities for the horse riding sport. Therefore, the purpose of this KIEM project is to start an interdisciplinary collaboration between parties interested in integrating existing knowledge on horse and (disabled) rider interaction with any novel insights to be gained from analysing recently collected sensor data using the EquiMoves™ system. EquiMoves is based on the state-of-the-art inertial- and orientational-sensor system ProMove-mini from Inertia Technology B.V., a partner in this proposal. On the basis of analysing previously collected data, machine learning algorithms will be selected for implementation in existing or modified EquiMoves sensor hardware and software solutions. Target applications and follow-ups include: - Improving horse and (disabled) rider interaction for riders of all skill levels; - Objective evidence-based classification system for competitive grading of disabled riders in Para Dressage events; - Identifying biomechanical irregularities for detecting and/or preventing injuries of horses. Topic-wise, the project is connected to “Smart Technologies and Materials”, “High Tech Systems & Materials” and “Digital key technologies”. The core consortium of Saxion University of Applied Sciences, Rosmark Consultancy and Inertia Technology will receive feedback to project progress and outcomes from a panel of international experts (Utrecht University, Sport Horse Health Plan, University of Central Lancashire, Swedish University of Agricultural Sciences), combining a strong mix of expertise on horse and rider biomechanics, veterinary medicine, sensor hardware, data analysis and AI/machine learning algorithm development and implementation, all together presenting a solid collaborative base for derived RAAK-mkb, -publiek and/or -PRO follow-up projects.
In this project, Photons in Focus, researchers from The Hague University of Applied Sciences will work together with the company Photosynthetic to fabricate high-quality microlenses that will optimally focus light onto microscopic light detectors. Specifically, the microlenses will be designed to focus light onto superconducting nanowire single-photon detectors (SNSPDs) from the company Single Quantum. SNSPDs are cryogenic single-photon detectors with photon detection efficiencies up to 99% and timing resolutions down to 15 picosecond. Recently, Single Quantum has been developing arrays of SNSPDs for free-space biomedical imaging and deep space communications. The photon detection efficiency of these arrays is suboptimal, because 15-20% of the light falls onto nonsensitive areas. In Photons in Focus, fabrication of two types of microstructures will be explored for optimally focusing light onto these SNSPDs and improving the photon detection efficiency. First, 3-dimensional microlenses will be created at Photosynthetic using their method of dual-wavelength volumetric microlithography. Second, phase-reversal Fresnel zone plates will be fabricated using standard 2-dimensional photolithography at The Hague University of Applied Sciences. Both types of microstructures will be tested for their focusing properties and potential optical losses, and their ability to enhance to photon detection efficiency of SNSPDs in cryogenic conditions.
Bicycle manufacturing currently falls behind the fast technological developments in automotive industries. We propose to design, develop and test a smart cycling eco-system where bicycles communicate in realtime with each other, and with the urban transport infrastructure (e.g. traffic lights) to optimize the use and improve traffic safety, economical value, and efficiency. This require technologies and mechanisms to allow monitoring the bike, understanding the cyclist and the context, as well as data sharing between cyclists, industry, service providers, government, and urban planners. The new eco-system can drive decision-making, behaviour incentivisation, and ultimately investment, across government, and beyond. A key ingredient is an AI-enabled IoT ecosystem in which data is securely collected, shared, processed in combination with other data sources, and made available to establish new services. This allows to reliably identify relevant events (like dangerous situations), detect trends (like decreasing performance of components, allowing maintenance to be performed in time), and give new insights to the user (such as health and performance).
