Impact of different types of revision materials on the learning of musculoskeletal techniques

International audienceBackground: This study aimed to measure the impact of different revision materials developed for osteopathy students, by studying their results, their perceptions and their behaviour when revising for exams. Methods: A cohort of 68 second-year osteopathic students was allocated to three groups (pseudo-randomisation), each group being separately taught the same practical course, but provided with different types of revision materials (video, digital data sheet and no material). They were then assessed by an external examiner. Outcome measures were grades, time spent revising on the platform and student material perceptions collected via a practical assessment, by monitoring student visits on an education platform (Tactiléo®) and a questionnaire. Results: The results showed that the mean exam grades for the Video group were 14% higher than those of the No Materials group (p = 0.04, d = 0.94) and 29% higher than the Digital Data Sheet group (p < 0.01, d = 1.36). In addition, an interesting result was that students from the Video group spent more time using the revision materials (+29%), consulted them more often (+25%) and repeated their techniques more often than students in the Digital Data Sheet group (+14%). Conclusions: The use of video revision material improved participants' results while exerting a positive influence on their behaviour when revising but did not prevent surface learning. A structured teaching and learning approach will therefore need to be implemented if learners are to get all the benefits of video materials while being more engaged on a personal level

Analyse biomécanique du complexe lombo-pelvi-fémoral complex during the one-sided tilt test ::a pilot study in triathletes

Introduction: The evaluation of the risk of low back pain remains complex as it lacks evidence-based recommendations and a reliable functional test. The one-sided tilt test can provide additional information on the dynamics of the lumbo- pelvic complex. However, little is known about the expected movement. This study aims to identify different patterns of movement during the test in a healthy population of triathletes and provide preliminary normative values. Method: Twenty-tvvo asymptomatic triathletes were instructed to perform the right and left one-sided tilt test. Three-dimensional kinematics were obtained from a 24-camera motion analysis system. This made it possible to mode! the range of motions of the torso, the pelvis, the hips and the kneesusing OpenSim. Latent class analysis was then used to identify different classes of movement combination. Results: Four classes of possible movement combinations w ere identified. Knee flexion was most limited with reduced range of pelvis tilt motion, then rotation, and fina lly list. These patterns were different between the left and right side in 31.8% of the studied population. Discussion: This approach enabled the ident ification of athletes with limited range of motion on the lumbar-pelvic-femoral complex. Conclusions : Polyarticular functional movement could help understand different strategies and kinematic adaptations linked to over- or under- mechanical load of specific joints.Introduction: L’évaluation du risque de lombalgie demeure complexe, car elle manque de recommandations fondées sur des données probantes et de tests fonctionnels fiables. Le test d’inclinaison unilatérale du bassin propose une analyse dynamique du complexe lombo-pelvi-fémoral. Il n’existe cependant pas de description quantitative du mouvement attendu chez une population asymptomatique de triathlètes. Cette étude vise à identifier et à différencier des schémas de mouvement du complexe lombo-pelvi-fémoral lors du test et d’en fournir des premières valeurs normatives. Méthode: Vingt-deux triathlètes asymptomatiques ont reçu l’instruction d’effectuer le test d’inclinaison latérale du bassin de manière bilatérale. La cinématique 3D a été obtenue à partir d’un système d’analyse de mouvement à 24 caméras. Ceci a permis de modéliser via OpenSim l’amplitude articulaire du mouvement effectué par le tronc, le bassin, les hanches et les genoux. Une analyse de classe par latence a permis d’identifier les «classes» de mouvements possibles. Résultats : Quatre classes de mouvements possibles ont été identifiées. La mobilisation du genou était limitée au maximum en présence d’une limitation de l’inclinaison du bassin, puis de la rotation du bassin, et finalement de l’antéversion du bassin. Ces schémas étaient présents de manière différenciée entre le côté gauche et le côté droit chez 31.8% des participants. Discussion: Cette approche permet d’identifier des athlètes ayant des limitations de mobilité du complexe lombo-pelvifémoral. Conclusion: L’interprétation du mouvement fonctionnel polyarticulaire pourrait aider à identifier et comprendre différentes stratégies ou adaptations cinématiques expliquant la sur ou sous sollicitation de certaines articulations

Learning strategies of osteopathic techniques and clinical decision-making. Implications for osteopathic education. Preliminary study

International audienceA number of different osteopathic techniques can be observed nowadays (Fryer, 2008). The teaching of these techniques is widely dependent on strategies chosen by the schools and their teaching staff (Browning et al. 2010). In addition, many different techniques and practices can be recorded across Europe, despite the teachings of Andrew Taylor Still who founded Osteopathy (Still, 1910). One of the reasons behind such findings could be that field experience would be the source of integrated skills among therapists. This study puts forward a methodology that allows the analysis of practices by experienced osteopaths. The aim of this preliminary study was to analyse the different integrated skills used in their practice, thus reflecting on their acquisition skills and their future teachings
