However, the underlying injury mechanisms and the role of muscle activity are not fully clear. Potential increases in injury risk of non-nominal postures, i.e., rotated head, cannot be evaluated in detail due to the lack of experimental data. Examining changes in neck muscle activity to hold and stabilize the head in a rotated position during pre-crash scenarios might provide a deeper understanding of muscle reflex contributions and injury mechanisms. In this study, the influence of two different head postures (nominal vs. rotation of the head by about 63\u2009±\u20099° to the right) on neck muscle activity and head kinematics was investigated in simulated braking experiments inside a driving simulator. The braking scenario was implemented by visualization of the virtual scene using head-mounted displays and a combined translational-rotational platform motion. Kinematics of seventeen healthy subjects was tracked using 3D motion capturing. Surface electromyography were used to quantify muscle activity of left and right sternocleidomastoideus (SCM) and trapezius (TRP) muscles. The results show clear evidence that rotated head postures affect the static as well as the dynamic behavior of muscle activity during the virtual braking event. With head turned to the right, the contralateral left muscles yielded higher base activation and delayed muscle onset times. In contrast, right muscles had much lower activations and showed no relevant changes in muscle activation between nominal and rotated head position. The observed delayed muscle onset times and increased asymmetrical muscle activation patterns in the rotated head position are assumed to affect injury mechanisms. This could explain the prevalence of rotated head postures during a crash reported by patients suffering from WAD. The results can be used for validating the active behavior of human body models in braking simulations with nominal and rotated head postures, and to gain a deeper understanding of neck injury mechanisms.", "doi" : "10.1007/s10439-022-03087-9", "bibtexKey": "noauthororeditor2024rotated" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2eeb7eec4365e95de248e73401073785a/inspo5", "tags" : [ "Biaxial","Biological","Stress-strain-relationship","mechanics","stomach","tissue","Inspo","testing","tensile","soft","Porcine","Organ" ], "intraHash" : "eeb7eec4365e95de248e73401073785a", "interHash" : "252446e0dc715c88dc9bb6f9988761ec", "label" : "Regional differences in stomach stretch during organ filling and their implications on the mechanical stress response", "user" : "inspo5", "description" : "", "date" : "2024-04-30 15:05:35", "changeDate" : "2024-04-30 15:05:35", "count" : 2, "pub-type": "article", "journal": "Journal of Biomechanics","publisher":"Elsevier BV", "year": "2024", "url": "http://dx.doi.org/10.1016/j.jbiomech.2024.112107", "author": [ "Stefan Papenkort","Mischa Borsdorf","Simon Kiem","Markus Böl","Tobias Siebert" ], "authors": [ {"first" : "Stefan", "last" : "Papenkort"}, {"first" : "Mischa", "last" : "Borsdorf"}, {"first" : "Simon", "last" : "Kiem"}, {"first" : "Markus", "last" : "Böl"}, {"first" : "Tobias", "last" : "Siebert"} ], "editor": [ "Tobias Siebert" ], "editors": [ {"first" : "Tobias", "last" : "Siebert"} ], "volume": "168","pages": "112107","abstract": "As part of the digestive system, the stomach plays a crucial role in the health and well-being of an organism. It produces acids and performs contractions that initiate the digestive process and begin the break-up of ingested food. Therefore, its mechanical properties are of interest. This study includes a detailed investigation of strains in the porcine stomach wall during passive organ filling. In addition, the observed strains were applied to tissue samples subjected to biaxial tensile tests. The results show inhomogeneous strains during filling, which tend to be higher in the circumferential direction (antrum: 13.2%, corpus: 22.0%, fundus: 67.8%), compared to the longitudinal direction (antrum: 4.8%, corpus: 24.7%, fundus: 50.0%) at a maximum filling of 3500 ml. Consequently, the fundus region experienced the greatest strain. In the biaxial tensile experiments, the corpus region appeared to be the stiffest, reaching nominal stress values above 400 kPa in the circumferential direction, whereas the other regions only reached stress levels of below 50 kPa in both directions for the investigated stretch range. Our findings gain new insight into stomach mechanics and provide valuable data for the development and validation of computational stomach models.", "language" : "English", "issn" : "0021-9290", "doi" : "10.1016/j.jbiomech.2024.112107", "bibtexKey": "Papenkort_2024" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/243c7d8d7611bdcf9c01955ccd18e1576/inspo5", "tags" : [ "tension","Biaxial","experiments","staining","Layer","specific","Tissue","muscle","testing","Smooth","Microstructure" ], "intraHash" : "43c7d8d7611bdcf9c01955ccd18e1576", "interHash" : "1c551a3d7362260e9dc45aeb1d271fa4", "label" : "Location- and layer-dependent biomechanical and microstructural characterisation of the porcine urinary bladder wall", "user" : "inspo5", "description" : "", "date" : "2022-07-19 11:10:29", "changeDate" : "2022-07-19 09:10:56", "count" : 2, "pub-type": "article", "journal": "Journal of the Mechanical Behavior of Biomedical Materials","publisher":"Elsevier BV", "year": "2021", "url": "https://doi.org/10.1016%2Fj.jmbbm.2020.104275", "author": [ "Robin Trostorf","Enrique Morales-Orcajo","Tobias Siebert","Markus Böl" ], "authors": [ {"first" : "Robin", "last" : "Trostorf"}, {"first" : "Enrique", "last" : "Morales-Orcajo"}, {"first" : "Tobias", "last" : "Siebert"}, {"first" : "Markus", "last" : "Böl"} ], "editor": [ "Tobias Siebert" ], "editors": [ {"first" : "Tobias", "last" : "Siebert"} ], "volume": "115","pages": "104275", "doi" : "10.1016/j.jmbbm.2020.104275", "bibtexKey": "Trostorf_2021" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2714e20216ab260122aab18992916b89a/hermann", "tags" : [ "software","testing","debugging","diss" ], "intraHash" : "714e20216ab260122aab18992916b89a", "interHash" : "74cd7efe7bc66d6ca18165c76d848a55", "label" : "Test-driven Development - by example.", "user" : "hermann", "description" : "", "date" : "2020-11-30 13:25:08", "changeDate" : "2020-11-30 12:25:08", "count" : 3, "pub-type": "book", "series": "The Addison-Wesley signature series","publisher":"Addison-Wesley", "year": "2003", "url": "", "author": [ "Kent L.
