While the subjects perform continuous plantar- and dorsiflexion movements in two different controlled velocities, the ultrasound probe sweeps cyclically from the ankle to the knee along the anterior shin. The ankle joint angle can be determined using reflective motion capture markers. Since we considered the movement direction of the foot, i.e., active or passive TA, four conditions occur: slow active, slow passive, fast active, fast passive. By employing an algorithm which defines ankle joint angle intervals, i.e., intervals of range of motion (ROM), 3D images of the volumes during movement can be reconstructed.\r\n\r\nResults: We found constant muscle volumes between different muscle lengths, i.e., ROM intervals. The results show an increase in mean cross-sectional area (CSA) for TA muscle shortening. Furthermore, a shift in maximum CSA towards the proximal side of the muscle could be observed for muscle shortening. We found significantly different maximum CSA values between the fast active and all other conditions, which might be caused by higher muscle activation due to the faster velocity.\r\n\r\nConclusion: In summary, we present a method for determining muscle volume deformation during dynamic contraction using ultrasound, which will enable future empirical studies and 3D computational models of skeletal muscles.", "language" : "English", "doi" : "10.3389/fbioe.2024.1388907", "bibtexKey": "siebert2024determination" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2fd36e7e13c488bf8e769fe41bed60dc3/inspo5", "tags" : [ "Longitudinal","femoris","functions","muscle","rectus","intramuscular","dynamic","human","sequencing" ], "intraHash" : "fd36e7e13c488bf8e769fe41bed60dc3", "interHash" : "9c585a2d480703d099c25ec697d427ed", "label" : "Longitudinal sequencing in intramuscular coordination: A new hypothesis of dynamic functions in the human rectus femoris muscle", "user" : "inspo5", "description" : "", "date" : "2022-07-19 11:10:29", "changeDate" : "2022-07-19 09:10:56", "count" : 1, "pub-type": "article", "journal": "PLOS ONE","publisher":"Public Library of Science", "year": "2017", "url": "https://doi.org/10.1371/journal.pone.0183204", "author": [ "Christoph von Laßberg","Julia A.

It describes general principles of intersegmental neuromuscular succession patterns to most efficiently generate specific movement intentions. The general hypothesis of this study is that these principles\u2014if they really do indicate a fundamental basis for efficient movement generation\u2014should also be found in intramuscular coordination and should be indicated by \u201Clongitudinal sequencing\u201D between fibers according to the principles of the punctum fixum-punctum mobile model. Based on this general hypothesis an operationalized model was developed for the rectus femoris muscle (RF), to exemplarily scrutinize this hypothesis for the RF. Electromyography was performed for 14 healthy male participants by using two intramuscular fine wire electrodes in the RF (placed proximal and distal), three surface electrodes over the RF (placed proximal, middle, and distal), and two surface electrodes over the antagonists (m. biceps femoris and m. semitendinosus). Three movement tasks were measured: kicking movements; deceleration after sprints; and passively induced backward accelerations of the leg. The results suggest that proximal fibers can be activated independently from distal fibers within the RF. Further, it was shown that the hypothesized function of \u201Cintramuscular longitudinal sequencing\u201D does exist during dynamic movements. According to the punctum fixum-punctum mobile model, the activation succession between fibers changes direction (from proximal to distal or inversely) depending on the intentional context. Thus, the results seem to support the general hypothesis for the RF and could be principally in line with the operationalized \u201Cinter-fiber to tendon interaction model\u201D.", "isbn" : "PMID: 28817715", "issn" : "PMCID: PMC5560678", "doi" : "10.1371/journal.pone.0183204", "bibtexKey": "10.1371/journal.pone.0183204" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/220aac70d92fb99729b91ffe1c3adb342/inspo5", "tags" : [ "Motion","Myofascial","Dynamic","of","Range","Static","Stretching" ], "intraHash" : "20aac70d92fb99729b91ffe1c3adb342", "interHash" : "998f4bb115946256f369303b1f4fc79c", "label" : "Effect of Static Stretching, Dynamic Stretching, and Myofascial Foam Rolling on Range of Motion During Hip Flexion: A Randomized Crossover Trial", "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 Strength and Conditioning Research","publisher":"Ovid Technologies (Wolters Kluwer Health)", "year": "2022", "url": "https://doi.org/10.1519%2Fjsc.0000000000003517", "author": [ "Tobias Siebert","Lars Donath","Mischa Borsdorf","Norman Stutzig" ], "authors": [ {"first" : "Tobias", "last" : "Siebert"}, {"first" : "Lars", "last" : "Donath"}, {"first" : "Mischa", "last" : "Borsdorf"}, {"first" : "Norman", "last" : "Stutzig"} ], "editor": [ "Tobias Siebert" ], "editors": [ {"first" : "Tobias", "last" : "Siebert"} ], "volume": "36","number": "3","pages": "680--685", "language" : "English", "doi" : "10.1519/jsc.0000000000003517", "bibtexKey": "Siebert_2022" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/250eb44f91950357cf988eb9394027e14/carsten.scherer", "tags" : [ "robust","multiobjective","synthesis","control","imng","feasibility","h-infinity","inequalities","bilinear","algorithms","formulas","linear-systems","global","h-2","matrix","uncertainty","output-feedback","optimization","design","parameter","peerReviewed","lmis","structured","dynamic","order" ], "intraHash" : "50eb44f91950357cf988eb9394027e14", "interHash" : "79b43995f394ecc9dbf6ddc0aa390ca5", "label" : "Robust output-feedback controller design via local BMI optimization", "user" : "carsten.scherer", "description" : "", "date" : "2021-12-07 20:40:52", "changeDate" : "2021-12-07 19:40:52", "count" : 4, "pub-type": "article", "journal": "Automatica", "year": "2004", "url": "https://doi.org/10.1016/j.automatica.2004.01.028", "author": [ "S.

In this paper a new approach is proposed to the design of locally optimal controllers. It is iterative by nature, and starting from any initial feasible controller it performs local optimization over a suitably defined non-convex function at each iteration. The approach features the properties of computational efficiency, guaranteed convergence to a local optimum, and applicability to a very wide range of problems. Furthermore, a fast (but conservative) LMI-based procedure for computing an initially feasible controller is also presented. The complete approach is demonstrated on a model of one joint of a real-life space robotic manipulator. (C) 2004 Elsevier Ltd.
