    <title language="deu">Transport von schwer verletzten Traumapatienten im Rettungswagen mit und ohne starre Halsorthese: vergleichende biomechanische Messungen</title>
    <abstract language="deu">Hintergrund: &#13;
Der tatsächliche Stellenwert der prähospitalen Immobilisation der&#13;
Halswirbelsäule (HWS) bei schwer verletzten Traumapatienten ist weiterhin unklar.&#13;
In Anbetracht möglicher negativer Implikationen durch das Anbringen einer starren&#13;
HWS-Orthese muss deren Anwendung während der gesamten prähospitalen Phase&#13;
kritisch hinterfragt werden.&#13;
Ziel der Arbeit: &#13;
Es sollten vergleichende biomechanische Messungen zur Beweglichkeit&#13;
der HWS bei Immobilisation mittels Vakuummatratze mit und ohne zusätzliches&#13;
Anbringen einer starren HWS-Orthese nach Lagerung auf der Trage durchgeführt&#13;
werden.&#13;
Material und Methoden: &#13;
Die Bewegungen der HWS beim Ein- und Ausladeprozess&#13;
in einen modernen RTW sowie während der Fahrt entlang eines vordefinierten&#13;
Parkours wurden mit einem Motion-Capture-System aufgezeichnet. Die Probandin,&#13;
an der die Messungen durchgeführt wurden, wurde auf einer Vakuummatratze mit&#13;
der Möglichkeit zur seitlichen Fixierung des Kopfes sowie Kinn- und Stirngurt auf&#13;
einer elektrohydraulischen Fahrtrage immobilisiert. Bei der einen Hälfte der Versuche&#13;
erfolgte die zusätzliche Immobilisation der HWS mittels starrer Orthese, bei der&#13;
anderen wurde auf die Anwendung einer HWS-Orthese verzichtet.&#13;
Ergebnisse: &#13;
Statistisch signifikante Unterschiede ergaben sich nur bei einigen&#13;
biomechanischen Parametern in der sagittalen Ebene (Flexion und Extension). Für&#13;
die anderen Bewegungsrichtungen (axiale Rotation, laterale Beugung) wurden keine&#13;
signifikanten Unterschiede für die gemessenen Parameter ermittelt. Generell wurden&#13;
sowohl bei den Versuchen mit HWS-Orthese als auch ohne HWS-Orthese nur sehr&#13;
geringe Winkelauslenkungen (im Mittel bei axialer Rotation und Flexion/Extension im&#13;
Bereich von einem bis 2 Grad, bei der lateralen Beugung höchstens 3 Grad) gemessen.&#13;
Schlussfolgerung: Bei einer korrekt durchgeführten Immobilisation mittels einer&#13;
Vakuummatratze mit der Möglichkeit zur seitlichen Stabilisierung des Kopfes sowie&#13;
Kinn- und Stirngurt auf einer elektrohydraulischen Fahrtrage mit Beladesystem&#13;
ergeben sich für den Ein- und Ausladeprozess sowie während der Fahrt in einem&#13;
modernen RTW mit luftgefederter Tragenlagerung und Luftfederung der Hinterachse&#13;
keine relevanten Vorteile bezüglich der Einschränkung der Bewegung der HWS durch&#13;
die zusätzliche Verwendung einer starren HWS-Orthese.</abstract>

    <title language="eng">Biomechanical exposition of the factors influencing the pelvic floor muscle activity</title>
    <abstract language="eng">Introduction&#13;
About 40 % of the women worldwide suffer from Pelvic Floor Dysfunctions [1]. In previous studies, musculoskeletal simulations helped to understand and facilitate the complex issues of musculoskeletal disorders in several different branches [2, 3]. A fundamental prerequisite for the generation of these models is to have a basic understanding of the stresses acting on the pelvic floor. The aim of this study is to investigate the biomechanical factors influencing the activity of the pelvic floor muscles by establishing a parameterised model.&#13;
&#13;
Methods &#13;
To identify the factors that affect the pelvic floor muscles, the process is divided into several stages. The first step is to investigate the loads acting on the pelvic floor. For this, a simplified sagittal cross-sectional model of the upper body is analysed. The discretization of the abdominal cavity is presented with resulting force vectors representing the organs in the abdominal and pelvic region, the tensile force of the structures that fixate the organs as well as the intraabdominal pressure. &#13;
A second step is the examination of the basic mechanics of the pelvic floor muscles. As the functional anatomy of these muscles demonstrate differences compared to other muscle groups [4], the understanding of how they differ is crucial for the construction of musculoskeletal models.&#13;
After a static examination of loads on a simplified muscle model, an extended model including the physiological properties of a muscle must be involved in the considerations. Therefore, the influence of parameters such as the ideal muscle strength and fibre length, as well as elasticity or passive stiffness of the elements must be taken into account. The influencing factors of the variables can be analysed in a simplified pelvic floor muscle model by systematically changing the parameters.&#13;
&#13;
Results&#13;
The process of analysing the factors influencing the activity of the pelvic floor muscles follows two main strategies. The review of the effects of the whole body identifies the forces acting on the pelvic floor muscles and effect their activity. &#13;
With the examination of the basic mechanics of a simplified pelvic floor muscle model a better understanding is achieved of how the pelvic floor muscles absorb the loads acting in the body.&#13;
&#13;
Discussion&#13;
This process results in the main influence factors on the activity of the pelvic floor. The consequent parameters form the basis for a biomechanically justified construction of musculoskeletal simulation models of the pelvic floor. Nevertheless, it must be considered, that these mechanical studies represent simplifications of the reality.&#13;

    <title language="eng">Workflow for the development of a non-invasive feedback device to assess pelvic floor contractions</title>
    <abstract language="eng">Introduction&#13;
Pelvic floor disorders affect about 40% of women worldwide [1]. Pelvic floor muscle (PFM) training is both a preventive and a therapeutic intervention. Current PFM training devices are invasive and have little scientific evidence. The idea is to develop a noninvasive feedback device to assess adequate PFM contraction. Therefore, evidence-based female musculoskeletal models, non-invasive data acquisition, sensor technology and artificial intelligence (AI) will be combined. This work presents the workflow to achieve such a feedback device and describes the interaction of the technologies used.&#13;
Methods&#13;
Exercises that induce PFM contractions have been evaluated and defined. Motion capture of these exercises will provide input for female musculoskeletal models. A combination of biomechanical rigid body and FEM simulations will be used to estimate PFM contractions. In addition, a non-invasive sensor will measure pelvic floor activity. The simulated and measured data will be used to develop an AI model that provides feedback on PFM contractions based on non-invasive data collection.&#13;
Results&#13;
The AMMR (AnyBody Managed Model Repository) of the AnyBody modelling system (AMS, Aalborg, Denmark) serves as the initial model for performing inverse dynamic simulations of the exercises. To calculate the PFM forces, the full-body model must be supplemented with the relevant pelvic floor structures and a mass model of the internal organs. A modified abdominal pressure model must also be incorporated. The AMS calculates the PFM activities caused by the internal organ loads and the generated abdominal pressure during the exercises. The muscle activities are transferred to a FEM model of the female pelvic floor (SfePy, simple finite elements in Python). The identical pelvic floor structures were integrated into the FEM model as in the AMS. Active PFM contractions can be simulated using the FEM model. Movement of the coccyx due to PFM contractions has been reported in the literature [2,3]. Therefore, a noninvasive coccyx motion sensor will be developed to provide additional information on PFM contractions. The measured data (coccyx motion sensor, motion capture) and the simulation results of the models will be combined to create an AI feedback model using Python. The final feedback device will consist of the AI model and the developed coccyx motion sensor, which can reproduce the resulting PFM contractions based on the sensor data and simplified motion tracking.&#13;
Discussion&#13;
The creation of the AMS and the FEM model is a prerequisite for the development of the feedback device. The relevant structures in the models are located inside the body. This limits the ability to observe the structures during the exercises, which can lead to difficulties in model validation. The development of a user-friendly sensor with sufficient measuring accuracy of the coccyx motion is another challenge. Nevertheless, the workflow represents a promising approach to develop a noninvasive feedback system to assess PFM contraction.&#13;

    <title language="eng">Assessment of implant internal stresses under physiological femoral loading: Translation to a simplified bending load model</title>
    <abstract language="eng">The success of surgical treatment for fractures hinges on various factors, notably accurate surgical indication. The process of developing and certifying a new osteosynthesis device is a lengthy and costly process that requires multiple cycles of review and validation. Current methods, however, often rely on predecessor standards rather than physiological loads in specific anatomical locations. This study aimed to determine actual loads experienced by an osteosynthesis plate, exemplified by a standard locking plate for the femoral shaft, utilizing finite elements analysis (FEA) and to obtain the bending moments for implant development standard tests. A protocol was developed, involving the creation and validation of a fractured femur model fixed with a locking plate, mechanical testing, and FEA. The model’s validation demonstrated exceptional accuracy in predicting deformations, and the FEA revealed peak stresses in the fracture bridging zone. Results of a parametric analysis indicate that larger fracture gaps significantly impact implant mechanical behavior, potentially compromising stability. This study underscores the critical need for realistic physiological conditions in implant evaluations, providing an innovative translational approach to identify internal loads and optimize implant designs. In conclusion, this research contributes to enhancing the understanding of implant performance under physiological conditions, promoting improved designs and evaluations in fracture treatments.</abstract>

    <title language="eng">Using markerless motion capture and musculoskeletal models: An evaluation of joint kinematics</title>
    <abstract language="eng">BACKGROUND: This study presents a comprehensive comparison between a marker-based motion capture system (MMC) and a video-based motion capture system (VMC) in the context of kinematic analysis using musculoskeletal models. OBJECTIVE: Focusing on joint angles, the study aimed to evaluate the accuracy of VMC as a viable alternative for biomechanical research. &#13;
&#13;
METHODS: Eighteen healthy subjects performed isolated movements with 17 joint degrees of freedom, and their kinematic data were collected using both an MMC and a VMC setup. The kinematic data were entered into the AnyBody Modelling System, which enables the calculation of joint angles. The mean absolute error (MAE) was calculated to quantify the deviations between the two systems. &#13;
&#13;
RESULTS: The results showed good agreement between VMC and MMC at several joint angles. In particular, the shoulder, hip and knee joints showed small deviations in kinematics with MAE values of 4.8∘, 6.8∘ and 3.5∘, respectively. However, the study revealed problems in tracking hand and elbow movements, resulting in higher MAE values of 13.7∘ and 27.7∘. Deviations were also higher for head and thoracic movements. &#13;
&#13;
CONCLUSION: Overall, VMC showed promising results for lower body and shoulder kinematics. However, the tracking of the wrist and pelvis still needs to be refined. The research results provide a basis for further investigations that promote the fusion of VMC and musculoskeletal models.</abstract>

    <title language="eng">Technologies for Evaluation of Pelvic Floor Functionality: A Systematic Review</title>
    <abstract language="eng">Pelvic floor dysfunction is a common problem in women and has a negative impact ontheir quality of life. The aim of this review was to provide a general overview of the current state oftechnology used to assess pelvic floor functionality. It also provides literature research of the phys-iological and anatomical factors that correlate with pelvic floor health. The systematic review wasconducted according to the PRISMA guidelines. PubMed, ScienceDirect, Cochrane Library andIEEE databases were searched for publications on sensor technology for the assessment of pelvicfloor functionality. Anatomical and physiological parameters were identified through a manualsearch. In the systematic review 115 publications were included. 12 different sensor technologieswere identified. Information on the obtained parameters, sensor position, test activities and subjectcharacteristics were prepared in tabular form from each publication. 16 anatomical and physiologi- cal parameters influencing pelvic floor health were identified in 17 published studies and rankedfor their statistical significance. Taken together, this review could serve as a basis for the develop-ment of novel sensors which could allow for quantifiable prevention and diagnosis, as well as par-ticularized documentation of rehabilitation processes related to pelvic floor dysfunctions.</abstract>
