RESUMEN
Despite well-documented benefits, the effectiveness of some aspects of near-peer (NP) teaching in medical education within anatomy curricula remains unclear. Here, we explored the impact of various permutations of staff/student laboratory-based co-teaching in neuroanatomy by determining the optimal staff and student teaching combination. We assessed student perceptions and knowledge acquisition using three different co-teaching strategies. Second-year medical students at the University of Southampton were co-taught neuroanatomy by faculty staff and third-year medical students (NP teachers). Three cohorts, 2016/2017, 2017/2018, and 2018/2019, were included in the study. Subsequent cohorts experienced increasingly structured NP teaching with more NP teachers. Students completed evaluations for anatomy sessions, which were statistically compared. The 2017/2018 and 2018/2019 cohorts completed lunchtime quizzes matched to the learning outcomes of each practical session, which were analysed. A focus group involving six students was transcribed and thematically analysed. Anatomy practical ratings were significantly higher when both session structure and NP teacher numbers increased from 3 to 5-6 (p = 0.0010) and from 3 to 7-8 (p = 0.0020). There were no significant differences in anatomy practical ratings using 5-6 and 7-8 NP teachers (p > 0.9999). There were no significant differences between the knowledge scores of students who experienced 5-6 and 7-8 NP teachers. Themes detailing the benefits of NP teaching and the importance of faculty involvement were identified, demonstrating that students appreciated NP teaching within a co-teaching environment. Therefore, increased NP teaching may augment students' perceptions and knowledge acquisition. In this context, the optimal number of NP teachers may sit between 5 and 8.
RESUMEN
INTRODUCTION: It is unclear whether hydrodilatation is beneficial in the management of frozen shoulder compared with other common conservative management modalities. This systematic review evaluates the efficacy of hydrodilatation for the management of frozen shoulder. SOURCES OF DATA: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. An extensive search of PubMed, Embase, Scopus, Cochrane Central, Web of Science and CINAHL databases using multiple keyword combinations of 'shoulder', 'rotator', 'adhesive capsulitis', 'hydrodilatat*', 'distension' since inception of the databases to June 2023 was implemented. AREAS OF AGREEMENT: Hydrodilatation leads to at least transient more marked improvements in shoulder disability and passive external rotation compared with intra-articular corticosteroid injections. AREAS OF CONTROVERSY: Hydrodilatation improves passive external rotation in the longer term. Moreover, hydrodilatation may be a preferable option over manipulation under anaesthesia, given its lower cost and better patient convenience. GROWING POINTS: Intensive mobilization after hydrodilatation is a promising adjuvant treatment option for patients suffering from a frozen shoulder. AREAS TIMELY FOR DEVELOPING RESEARCH: Although current evidence suggests that hydrodilatation provides a transient improvement in disability in patients with frozen shoulder, its clinical relevance remains unclear. Further research is necessary to establish its role in the management of the condition.
