@article{34481, abstract = {{Background: Differential learning (DL) is a motor learning method characterized by high amounts of variability during practice and is claimed to provide the learner with a higher learning rate than other methods. However, some controversy surrounds DL theory, and to date, no overview exists that compares the effects of DL to other motor learning methods.Objective: To evaluate the effectiveness of DL in comparison to other motor learning methods in the acquisition and retention phase.Design: Systematic review and exploratory meta-analysis.Methods: PubMed (MEDLINE), Web of Science, and Google Scholar were searched until February 3, 2020. To be included, (1) studies had to be experiments where the DL group was compared to a control group engaged in a different motor learning method (lack of practice was not eligible), (2) studies had to describe the effects on one or more measures of performance in a skill or movement task, and (3) the study report had to be published as a full paper in a journal or as a book chapter.Results: Twenty-seven studies encompassing 31 experiments were included. Overall heterogeneity for the acquisition phase (post-pre; I2 = 77%) as well as for the retention phase (retention-pre; I2 = 79%) was large, and risk of bias was high. The meta-analysis showed an overall small effect size of 0.26 [0.10, 0.42] in the acquisition phase for participants in the DL group compared to other motor learning methods. In the retention phase, an overall medium effect size of 0.61 [0.30, 0.91] was observed for participants in the DL group compared to other motor learning methods.Discussion/Conclusion: Given the large amount of heterogeneity, limited number of studies, low sample sizes, low statistical power, possible publication bias, and high risk of bias in general, inferences about the effectiveness of DL would be premature. Even though DL shows potential to result in greater average improvements between pre- and post/retention test compared to non-variability-based motor learning methods, more high-quality research is needed before issuing such a statement. For robust comparisons on the relative effectiveness of DL to different variability-based motor learning methods, scarce and inconclusive evidence was found.}}, author = {{Tassignon, Bruno and Verschueren, Jo and Baeyens, Jean-Pierre and Benjaminse, Anne and Gokeler, Alli and Serrien, Ben and Clijsen, Ron}}, issn = {{1664-1078}}, journal = {{Frontiers in Psychology}}, keywords = {{General Psychology}}, publisher = {{Frontiers Media SA}}, title = {{{An Exploratory Meta-Analytic Review on the Empirical Evidence of Differential Learning as an Enhanced Motor Learning Method}}}, doi = {{10.3389/fpsyg.2021.533033}}, volume = {{12}}, year = {{2021}}, } @article{34479, abstract = {{Background: The incidence of anterior cruciate ligament (ACL) injuries is commonly reported as an annual incidence rate. There is relatively little information about the seasonal aspects of these injuries. The aim of the current study was to analyze the distribution of ACL injuries during the season in nonprofessional soccer, handball, and basketball based on a retrospective analysis of a hospital-based registry. Hypothesis: ACL injuries in soccer, handball, and basketball were more common within the first 2 months of the season in comparison with the rest of the year. Study Design: Case series. Level of Evidence: Level 4. Methods: Injury occurrence during the calendar year was divided into 6 periods of 2 months, with segment 1 (S1) representing the first 2 months of the season. For soccer, S1 corresponded to September and October. The season started 1 month later for handball and basketball, so S1 represented October and November. Chi-square tests were used to analyze the distribution of ACL injuries among segments according to gender, age, sports, and injury mechanism (contact/noncontact). Results: A total of 371 ACL injuries were included (soccer, 258, handball, 56, basketball, 57). Overall, the distribution of ACL injuries was not uniform across the segments ( P < 0.01). Almost one-third of the ACL injuries occurred in S1 (n = 104; 28%). Significant differences could be observed according to sports ( P < 0.01). There were fewer ACL injuries in S2 for soccer compared with basketball ( P < 0.05). In S5, there were significantly more ACL injuries in soccer compared with handball and basketball ( P < 0.05). Conclusion: A high occurrence of ACL injuries was reported immediately within the first 2 months of the season in nonprofessional soccer, handball, and basketball sports. Clinical Relevance: These findings indicate that ACL injury prevention programs should be started in the preseason period to allow for gradual increases of load. }}, author = {{Mouton, Caroline and Gokeler, Alli and Urhausen, Anouk and Nührenbörger, Christian and Seil, Romain}}, issn = {{1941-7381}}, journal = {{Sports Health: A Multidisciplinary Approach}}, keywords = {{Physical Therapy, Sports Therapy and Rehabilitation, Orthopedics and Sports Medicine}}, number = {{2}}, pages = {{183--187}}, publisher = {{SAGE Publications}}, title = {{{High Incidence of Anterior Cruciate Ligament Injuries Within the First 2 Months of the Season in Amateur Team Ball Sports}}}, doi = {{10.1177/19417381211014140}}, volume = {{14}}, year = {{2021}}, } @article{34476, author = {{Rambaud, Alexandre JM and Neri, Thomas and Dingenen, Bart and Parker, David and Servien, Elvire and Gokeler, Alli and Edouard, Pascal}}, issn = {{1877-0657}}, journal = {{Annals of Physical and Rehabilitation Medicine}}, keywords = {{Rehabilitation, Orthopedics and Sports Medicine}}, number = {{4}}, publisher = {{Elsevier BV}}, title = {{{The modifying factors that help improve anterior cruciate ligament reconstruction rehabilitation: A narrative review}}}, doi = {{10.1016/j.rehab.2021.101601}}, volume = {{65}}, year = {{2021}}, } @article{26117, author = {{Büchel, Daniel and Lehmann, Tim and Ullrich, Sarah and Cockcroft, John and Louw, Quinette and Baumeister, Jochen}}, journal = {{Experimental Brain Research}}, number = {{1193-1202}}, title = {{{Stance leg and surface stability modulate cortical activity during human single leg stance}}}, volume = {{239}}, year = {{2021}}, } @article{34486, abstract = {{In inklusiven Schulen wird zunehmend ein stärker individualisierter Unterricht verfolgt.

Within Germany, the role of special education within inclusive schools has been widely discussed in Germany (Powell et al., 2016). Educators worldwide consider collaborative teaching between special educators and general educators to be a fundamental precondition for inclusive education (Hoppey & McLeskey, 2014). The history of the German school system, however, is characterized by a rigorous division of special and regular schools that is reflective of broad divisions in teacher education. Since the ratification of the Convention on the Rights of Persons with Disabilities (CRPD) in Germany in 2009, more students with special educational needs, as well as special educators, have begun to attend and work in inclusive schools. While cooperation between general and special educators is a key to the development of inclusive schools, many teachers report that responsibilities are divided between special and general teachers, while various challenges exist regarding cooperation (Urban & Lütje-Klose, 2014). Nevertheless, dysfunctional cooperation can foster mechanisms of separation and exclusion even in “inclusive” settings (Idel et al., 2019). The present chapter offers a reflection on the different roles of special educators and the current state of research on interdisciplinary and multi professional cooperation in inclusive schools in Germany.

To overcome this drawback, an innovative approach is the usage of individually produced and task-adapted JE, the so-called friction spun joint connectors (FSJC). These connectors can be modified in shape as well as in material properties. This flexibility offers high potential for lightweight design but also increases the necessary analytical effort regarding the forming process as well as the manufactured joint's properties. Therefore, a new analysis strategy based on the Finite-Element-Method (FEM) is proposed, which numerically determines the local load bearing capacity within a given joint in order to identify the critical regions for load transfer.
