Le dessin ostéopathique des atteintes corporelles : une clinique émersive
No full textInternational audienceObjective. – Osteopathy is the most popular alternative healthcare practice in France. To update and improve this practice, which is already part of patient care pathways, it is necessary to explore and understand bodily damage via a central idea in osteopathy: somatic dysfunction.Methods. – First-person data were collected using a consciousness drawing approach followed by explanatory interviews. During their first two years of osteopathic studies, students engage in a reflective practice around somatic dysfunction. This study utilized a qualitative method with a thematic analysis of the above interviews and drawings.Results. – The thematic analysis identified the existence of four axes: the reading of the bodily injury, the materialization of the bodily injury, the transition from local bodily injury to global bodily injury, and the impact of the bodily injury on the osteopath in the context of emerging intercorporeality. There were three categories of drawings: (drawings) of consciousness, drawings (of) consciousness, and drawings of (consciousness).Discussion. – Exploring knowledge about somatic dysfunction has highlighted that mixed epistemology is needed to propose a model of osteopathic clinical practice that incorporates elements of a bio- psychosocial approach. Touch seems to allow the identification of intercorporeality in the experiences of the therapist and patient, thanks to an emersive clinical experience of the body.Conclusion. – This study explores the knowledge and theories of osteopathic students in early training. Their conception of somatic dysfunction was expressed through several drawings of consciousness and through a narrative arising from bodily reflexivity. This work seems conducive to the better integration of psychosocialcriteria and a holistic understanding of the body, with a view to enhancing the contribution of osteopathic touch as care within a patient-centered approach.L’ostéopathie est la pratique de soins non conventionnelle la plus sollicitée par les Franc ¸ ais. Afin d’actualiser et faire progresser cette pratique déjà présente dans le parcours de soin des patients, ilsemble nécessaire de mieux explorer et comprendre l’atteinte corporelle à travers une notion centrale de la discipline ostéopathique : la dysfonction somatique.Méthode. – Une collecte de données en première personne est réalisée à partir de dessins de conscience puis d’entretiens d’explicitation. Au cours de leurs deux premières années en cur-sus ostéopathique, des étudiants sont engagés dans une pratique réflexive vis-à-vis de la dysfonction somatique. Cette étude repose sur une méthode qualitative avec une analyse thématique des entretiens et des dessins.Résultats. – L’analyse thématique permet d’identifier quatre axes : la lecture de l’atteinte corporelle, la matérialisation de l’atteinte corporelle, le passage d’une atteinte corporelle locale à une atteinteglobale et l’impact de cette atteinte corporelle sur l’ostéopathe dans une intercorporéité émergente. Les dessins révèlent trois catégo- ries : (dessin) de conscience, dessin (de) conscience et dessin de (conscience).Discussion. – L’exploration des connaissances de la dysfonction somatique permet de mettre en lumière la nécessité de proposer une épistémologie mixte pour proposer une modélisation de la pratique clinique ostéopathique intégrant les éléments d’une approche biopsychosociale. Le toucher semble permettre l’identification d’une intercorporéité entre le vécu du thérapeute et du patient, ceci grâce à une clinique émersive du corps.Conclusion. – Cette étude explore les connaissances et les théories du corps d’étudiants en début de cursus ostéopathique. Leur conception de la dysfonction somatique s’exprime au travers de plusieurs dessins de conscience ainsi que d’une narration dans une démarche de réflexivité corporelle. Ceci semble propice à une meilleure intégration de critères psychosociaux et une connaissance du corps holiste afin de valoriser la place de l’expérience vécue par le soin tactile ostéopathique dans une approche centrée sur le patient
L’évolution de la pharmacie en France : les risques induits par la transition numérique des officines
No full textLe numérique transforme le secteur officinal, en apportant des technologies innovantes qui améliorent la gestion des officines, optimisent les dispensations pharmaceutiques et renforcent la coordination entre professionnels de santé. Des outils comme les e-prescriptions, le dossier médical partagé ou encore la messagerie sécurisée de santé offrent des opportunités pour moderniser les pratiques pharmaceutiques et répondre aux besoins croissants des patients, notamment en termes d'accessibilité et de personnalisation des services. Cependant, cette transition numérique n’est pas sans risques. La sécurité des données de santé reste un enjeu majeur, nécessitant des réglementations strictes et des infrastructures adaptées. Par ailleurs, la digitalisation pose des enjeux éthiques importants, notamment le risque d’aggraver la fracture numérique d’une partie de la population et de réduire la qualité des interactions humaines entre les pharmaciens et leurs patients. Ainsi, si le numérique promet d’immenses bénéfices pour la pharmacie, il impose également des investissements, des adaptations et une vigilance constante pour en gérer les impacts
Creep in steel-concrete composite beams bonded by adhesive and connected by studs
No full textInternational audienceThis study investigates the creep behavior of steel-concrete composite beams, comparing traditional shear stud connections with adhesive bonding. Unlike shear studs, adhesive bonding distributes stress more evenly along the interface, reducing stress concentrations and enhancing structural performance. It also eliminates the need for welding or bolting, significantly reducing construction time-an advantage particularly beneficial for prefabricated and modular structures. Flexural creep tests were conducted under constant loads for 120 days, with longitudinal deformations monitored. Three-dimensional finite element models incorporating linear viscoelastic theory were developed to analyze strain and stress evolution. Results highlight significant differences: adhesivebonded beams exhibit lower creep strains and more uniform strain distribution compared to stud-connected beams. Creep strain follows a three-stage pattern: in the initial stage (0-9 days), adhesive bonding reduces the rate of creep increase by up to 39 %; in the second stage (10-80 days), by up to 33 %; and in the final stage, the creep stabilizes, with an overall reduction of up to 24 %. Finite element simulations further demonstrate that adhesive bonding enhances stress redistribution and ensures a more uniform creep variation along the beam's length, offering a promising alternative for long-term structural performance.</div
Aerodynamic challenges in running: Understanding headwind and tailwind effects
No full textInternational audienceThe primary objective of this study was to assess how wind affects metabolic cost of running. A numerical method was employed to investigate aerodynamic forces acting on a runner at three different running speeds (10, 15, and 20 km/h) while experiencing five headwind and tailwind speeds (ranging from 0 to 30 km/h). Additionally, a mathematical model was used to estimate aerodynamic and metabolic power based on both runner and wind speeds. Insights from the numerical investigation highlighted how wind conditions, including speed and direction, alter the turbulent wake behind the runner, ultimately affecting metabolic power requirements. While a 30 km/h tailwind leads to a modest 9% reduction in energy expenditure, a headwind of the same speed results in a substantial 37% increase. In practical terms, running at 13.7 km/h against a 20 km/h headwind imposes the same metabolic demand as running at 19.4 km/h with a 20 km/h tailwind. Furthermore, considering an out and back course, temporary tailwind advantages do not sufficiently offset headwind effects. Thus, this study underscores the critical need for runners to consider weather conditions, especially wind, to effectively manage energy expenditure and optimize performance in competitions or training sessions
Early Postoperative Evaluation of Arthrogenic Muscle Inhibition, Anterior Knee Laxity, and Kinesiophobia After ACL Reconstruction: A Cross-Sectional Observational Study
No full textInternational audienceBackground: Arthrogenic muscle inhibition (AMI), anterior knee laxity, and kinesiophobia are key barriers to recovery after anterior cruciate ligament reconstruction (ACLR). While each has been independently studied, their interrelationships during the early postoperative phase remain unclear. Methods: This cross-sectional study included 56 patients (mean age: 26.5 ± 5.7 years) who underwent ACLR using hamstring autografts. Clinical AMI grading, GNRB® arthrometer measurements of anterior tibial translation, and the Tampa Scale for Kinesiophobia-11 (TSK-11) were used to assess neuromuscular inhibition, mechanical laxity, and psychological fear, respectively. All evaluations were performed at 34.9 ± 4.2 postoperative days. Statistical analyses included one-way ANOVA, Kruskal–Wallis, and Spearman correlation. Results: No significant differences in TSK-11 scores were observed across AMI grades (p = 0.327). Similarly, anterior laxity did not differ significantly between AMI groups (p = 0.182). Correlation between GNRB measurements and TSK-11 scores was non-significant (rho = −0.220, p = 0.103). Conclusions: In the early phase following ACLR, AMI, anterior laxity, and kinesiophobia appear to be independent domains. These findings suggest that early postoperative rehabilitation should address each dimension individually. Further longitudinal studies are needed to explore their potential interactions over time
Influence of Graft Type on Muscle Contractile Dynamics After ACL Reconstruction: A 9-Month Tensiomyographic Follow-Up
No full textInternational audienceBackground: Persistent neuromuscular deficits following anterior cruciate ligament reconstruction (ACLR) are frequently attributed to arthrogenic muscle inhibition (AMI). The type of autologous graft used may influence the trajectory of neuromuscular recovery. Objective: To investigate the influence of graft type—bone–patellar tendon–bone (BPTB), hamstring tendon (HT), and quadriceps tendon (QT)—on the contractile properties of periarticular knee muscles over a 9-month post-operative period. Hypothesis: Each graft type would result in distinct recovery patterns of muscle contractility, as measured by tensiomyography (TMG). Methods: Thirty-one patients undergoing ACLR with BPTB (n = 8), HT (n = 12), or QT (n = 11) autografts were evaluated at 3, 6, and 9 months post-operatively. TMG was used to measure contraction time (Tc) and maximal displacement (Dm) in the rectus femoris, vastus medialis, vastus lateralis, and biceps femoris. Results: Significant within-group improvements in Tc and Dm were observed across all graft types from 3 to 9 months (Tc: p < 0.001 to p = 0.02; Dm: p < 0.001 to p = 0.01). The QT group showed the most pronounced Tc reduction in RF (from 30.16 ± 2.4 ms to 15.44 ± 1.6 ms, p < 0.001) and VM (from 31.05 ± 2.6 ms to 18.65 ± 1.8 ms, p = 0.004). In contrast, HT grafts demonstrated limited Tc recovery in BF between 6 and 9 months compared to BPTB and QT (p < 0.001), indicating a stagnation phase. BPTB exhibited persistent bilateral deficits in both quadriceps and BF at 9 months. Conclusions: Autograft type significantly influences neuromuscular recovery patterns after ACLR. TMG enables objective, muscle-specific monitoring of contractile dynamics and may support future individualized rehabilitation strategies
