However, 3D markerless motion capture based on pose estimation is advancing into the field of gait analysis. This study aims at evaluating the lower-body 3D gait kinematics and kinetics from synchronously recorded Theia3D markerless and CAST marker-based systems. Twelve healthy individuals and 34 clinical patients aged 8\u201361 years walked at self-selected speed over a 13 m long walkway. Similarity between models was statistically analysed using inter-trial variability, root mean square error, Pearson\u2019s correlation coefficient and Statistical Parametric Mapping. Inter-trial variability was on average higher for clinical patients in both models. Overall, the markerless system demonstrated similar gait patterns although hip and knee rotations were non-comparable. Pelvic anterior tilt was significantly underestimated. Significant differences especially in peak values at specific phases of the gait cycle were observed across all planes for all joints (more so for clinical patients than healthy subjects) as well as in the sagittal powers of the hip, knee and ankle. Theia3D markerless system offers great potential in gait analysis. This study brings awareness to potential clinical users and researchers where they can have confidence, as well as areas where caution should be exercised.", "doi" : "s41598-024-80499-8", "bibtexKey": "dsouza2024comparison" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/29fc3cfecc2c39e52b98d0b7689d90927/inspo5", "tags" : [ "myown","Passive","strength","isometric","muscle","of","motion","range" ], "intraHash" : "9fc3cfecc2c39e52b98d0b7689d90927", "interHash" : "c80ddfcaf1910d1f46a38466df87a8f6", "label" : "Reference measures of lower-limb joint range of motion, muscle strength, and selective voluntary motor control of typically developing children aged 5\u201317 years", "user" : "inspo5", "description" : "", "date" : "2024-05-07 14:33:56", "changeDate" : "2024-08-07 11:29:43", "count" : 6, "pub-type": "article", "journal": "Journal of Children\u2019s Orthopaedics","publisher":"SAGE Publications", "year": "2024", "url": "http://dx.doi.org/10.1177/18632521241234768", "author": [ "Emily Scherff","Sabrina Elisabeth Schnell","Tobias Siebert","Sonia D\u2019Souza" ], "authors": [ {"first" : "Emily", "last" : "Scherff"}, {"first" : "Sabrina Elisabeth", "last" : "Schnell"}, {"first" : "Tobias", "last" : "Siebert"}, {"first" : "Sonia", "last" : "D\u2019Souza"} ], "editor": [ "Tobias Siebert" ], "editors": [ {"first" : "Tobias", "last" : "Siebert"} ], "pages": "1-10","abstract": "Background:\r\nJoint range of motion based on the neutral null method, muscle strength based on manual muscle testing, and selective voluntary motor control based on selective control assessment of the lower extremity are standard parameters of a pediatric three-dimensional clinical gait analysis. Lower-limb reference data of children are necessary to identify and quantify abnormalities, but these are limited and when present restricted to specific joints or muscles.\r\nMethods:\r\nThis is the first study that encompasses the aforementioned parameters from a single group of 34 typically developing children aged 5\u201317\u2009years. Left and right values were averaged for each participant, and then the mean and standard deviation calculated for the entire sample. The data set was tested for statistical significance (p\u2009<\u20090.05).\r\nResults:\r\nJoint angle reference values are mostly consistent with previously published standards, although there is a large variability in the existing literature. All muscle strength distributions, except for M. quadriceps femoris, differ significantly from the maximum value of 5. The mean number of repetitions of heel-rise test is 12\u2009±\u20095. Selective voluntary motor control shows that all distributions, except for M. quadriceps femoris, differ significantly from the maximum value of 2.\r\nConclusion:\r\nSince typically developing children do not match expectations and reference values from the available literature and clinical use, this study emphasizes the importance of normative data. Excessively high expectations lead to typically developing children being falsely underestimated and affected children being rated too low. This is of great relevance for therapists and clinicians.", "language" : "English", "issn" : "1863-2548", "doi" : "10.1177/18632521241234768", "bibtexKey": "Scherff_2024" } , { "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/24295397405bd6b64c87b1b56bab3529b/inspo5", "tags" : [ "ergometer","SSC","potentiation","muscle","motion","capture","concentric","force","enhancement","eccentric" ], "intraHash" : "4295397405bd6b64c87b1b56bab3529b", "interHash" : "0535f924fe995f82ece9301a4bd96aa8", "label" : "10 % Higher Rowing Power Outputs After Flexion-Extension-Cycle Compared to an Isolated Concentric Contraction in Sub-Elite Rowers", "user" : "inspo5", "description" : "", "date" : "2022-07-19 11:10:29", "changeDate" : "2022-07-19 09:10:56", "count" : 2, "pub-type": "article", "journal": "Frontiers in Physiology","publisher":"Frontiers Media SA", "year": "2020", "url": "https://doi.org/10.3389%2Ffphys.2020.00521", "author": [ "Steffen Held","Tobias Siebert","Lars Donath" ], "authors": [ {"first" : "Steffen", "last" : "Held"}, {"first" : "Tobias", "last" : "Siebert"}, {"first" : "Lars", "last" : "Donath"} ], "editor": [ "Tobias Siebert" ], "editors": [ {"first" : "Tobias", "last" : "Siebert"} ], "volume": "11","abstract": "The resulting muscular performance is considered notably higher during a stretch shortening cycle (SSC) compared to an isolated concentric contraction. Thus, the present study examined the occurrence and magnitude of rowing performance enhancement after a flexion\u2013extension cycle (FEC) of the legs compared to both concentric contractions only and isometric pre-contraction. Therefore, 31 sub-elite male rowers (age: 25 ± 6 years, height: 1.90 ± 0.02 m, weight: 91 ± 10 kg, weekly training volume: 11.4 ± 5.3 h/week, rowing experience: 7.1 ± 2.7 years) randomly completed (a) isolated concentric rowing strokes (DRIVE), (b) single FEC-type rowing strokes (SLIDE-DRIVE), and (c) rowing strokes with an isometric pre-contraction (ISO-DRIVE). The resulting rowing power (Prow), leg power (Pleg), and work per stroke (WPS) were recorded using motion-capturing, force, and rotation sensors. Comparison of DRIVE and SLIDE-DRIVE revealed significantly (p < 0.05) higher Prow (+11.8 ± 14.0%), Pleg (+19.6 ± 26.7%), and WPS (+9.9 ± 10.5%) during SLIDE-DRIVE. Compared to ISO-DRIVE, Pleg (+9.8 ± 26.6%) and WPS (+6.1 ± 6.7%) are again significantly (p < 0.05) higher for SLIDE-DRIVE. In conclusion, notably higher work and power outputs (compared to an isolated concentric contraction) during FEC rowing referred to an underlying SSC. Future ultrasound studies should elucidate whether a real SSC on the muscle tendon unit level account for these performance enhancements.", "doi" : "10.3389/fphys.2020.00521", "bibtexKey": "Held_2020" } ] }
