Assessing the Educational Environment of a Flipped Physical Therapy Course: Utilization of the Dundee Ready Education Environment Measure (DREEM)

Purpose: Using valid and reliable measures to assess curricula within health professions programs has gained significant attention in recent years. The educational environment is considered a key domain for student success. The primary aim of this study was to measure the educational environment following the addition of a flipped classroom model within a physical therapy course as measured by the Dundee Ready Education Environment Measure. Methods: A first year doctorate of physical therapy course, “Physical Agents”, was redesigned to include a flipped classroom model, incorporating 24 videos that students reviewed independently, prior to hands-on laboratory learning. Following the conclusion of the course, students (n=57) completed the Dundee Ready Education Environment Measure, a valid and reliable survey designed to measure the educational environment within health profession programs. The Dundee Ready Education Environment Measure contains 50 items, rated from 0 to 4 (5-point Likert scale, “0” strongly disagree to “4” strongly agree), assessing five domains: students’ perceptions of learning; perceptions of teachers; academic self-perception; perceptions of atmosphere; and social self-perception. Descriptive statistics included mean global score (out of 200, 151 to 200 being an excellent environment) mean domain scores, and mean item scores. Cumulative grade point average between students in the flipped classroom model (n=58) and those who previously received a traditional teaching model (n=59) for the course were also compared. Student’s t-test was utilized with significance accepted at p\u3c0.05. Results: The mean global score (168 ± 13.3), indicated that the flipped classroom model fostered an excellent educational environment. Additionally, all mean domain scores, including students’ perceptions of learning (41.3 ± 3.9), perceptions of teachers (39.2 ± 2.9), academic self-perception (25.1 ± 2.5) perception of atmosphere (40.1 ± 4.1) and social self-perception (22.1 ± 2.9) fell into the highest rank of each subscale. Individual item analysis demonstrated 26 items (52%) were identified as especially strong areas, five items (10%) were identified as areas that could be improved, and no individual items were identified as requiring particular concern or immediate attention. Further, no significant differences were seen in cumulative course grade point average between the flipped classroom model (3.74 ± 0.44) and the traditional teaching model (3.71 ± 0.46). Conclusions: The flipped classroom model, utilizing an online learning environment, fostered an excellent educational environment for the physical therapy Physical Agents class. No difference in course grade point average between the flipped classroom model and previous traditional teaching model was seen. Further investigations examining performance on didactic and psychomotor activities within the flipped classroom model are recommended

Mechanical Instabilities of Biological Tubes

We study theoretically the shapes of biological tubes affected by various pathologies. When epithelial cells grow at an uncontrolled rate, the negative tension produced by their division provokes a buckling instability. Several shapes are investigated : varicose, enlarged, sinusoidal or sausage-like, all of which are found in pathologies of tracheal, renal tubes or arteries. The final shape depends crucially on the mechanical parameters of the tissues : Young modulus, wall-to-lumen ratio, homeostatic pressure. We argue that since tissues must be in quasistatic mechanical equilibrium, abnormal shapes convey information as to what causes the pathology. We calculate a phase diagram of tubular instabilities which could be a helpful guide for investigating the underlying genetic regulation

A Community-based Boxing Program is Associated with Improved Balance in Individuals with Parkinson’s Disease

International Journal of Exercise Science 14(3): 876-884, 2021. In alignment with efforts to mitigate the negative health consequences of Parkinson’s Disease (PD), the purpose of this investigation was to examine if participation in a community-based boxing program (CBP) was associated with improvements in balance and fall risk reduction among individuals with PD. In this retrospective cross-sectional study, de-identified data from 12 individuals with PD participating in a CBP was examined. Participants included those with a Hoehn and Yahr stage between 1 and 3, averaging 2.8 ± 0.8 CBP sessions per week for 6.1 ± 0.8 months between testing. Baseline and re-evaluation testing included the Fullerton Advanced Balance (FAB) Scale and Timed Up and Go (TUG) to quantify balance and fall risk. Sessions were 90-minutes in length involving a warm-up, boxing drills, strength and endurance exercises, and cool down. Sessions included multiple bouts of 30-60 second high-intensity exercise intervals (RPE between 15/20 to 17/20). Paired t-tests were used to determine if differences existed between the FAB and TUG from baseline to re-evaluation, with statistical significance accepted at p \u3c 0.05 and \u3e 0.8 interpreted as a large effect using Cohen’s d. Results indicated a statistically significant increase and large effect in FAB performance, with a mean increase in score above previously reported minimal detectable change (MDC). While participation in CBP was associated with a statistically significant improvement and medium effect in the TUG, this did not demonstrate a population specific MDC. This study found that participation in a CBP was associated with improved balance among clients with PD
