Background. Clinical practice for rehabilitation after mild traumatic brain injury (mTBI) is variable, and guidance on when to initiate physical therapy is lacking. Wearable sensor technology may aid clinical assessment, performance monitoring, and exercise adherence, potentially improving rehabilitation outcomes during unsupervised home exercise programs. Objective. The objectives of this study were to: (1) determine whether initiating rehabilitation earlier than typical will improve outcomes after mTBI, and (2) examine whether using wearable sensors during a home-exercise program will improve outcomes in participants with mTBI. Design. This was a randomized controlled trial. Setting. This study will take place within an academic hospital setting at Oregon Health & Science University and Veterans Affairs Portland Health Care System, and in the home environment. Participants. This study will include 160 individuals with mTBI. Intervention. The early intervention group (n = 80) will receive one-on-one physical therapy 8 times over 6 weeks and complete daily home exercises. The standard care group (n = 80) will complete the same intervention after a 6- to 8-week wait period. One-half of each group will receive wearable sensors for therapist monitoring of patient adherence and quality of movements during their home exercise program. Measurements. The primary outcome measure will be the Dizziness Handicap Inventory score. Secondary outcome measures will include symptomatology, static and dynamic postural control, central sensorimotor integration posturography, and vestibular-ocular-motor function. Limitations. Potential limitations include variable onset of care, a wide range of ages, possible low adherence and/or withdrawal from the study in the standard of care group, and low Dizziness Handicap Inventory scores effecting ceiling for change after rehabilitation. Conclusions. If initiating rehabilitation earlier improves primary and secondary outcomes post-mTBI, this could help shape current clinical care guidelines for rehabilitation. Additionally, using wearable sensors to monitor performance and adherence may improve home exercise outcomes., There is currently limited evidence supporting when rehabilitation for mild traumatic brain injury (mTBI) should be initiated, and as a result, clinical care guidelines for rehabilitation of mTBI lack consistency.

This study documented the means by which STEM (science, technology, engineering, and mathematics) educators experienced the mathematics and science associated with understanding lunar phenomena. The article reports how well STEM education graduate students interacted with project-based materials as they engaged in interdisciplinary teaching and learning. Research questions pursued were: (a) How will students 'spatial mathematics and scientific understandings develop as they engage in a contextualized, technology-rich, project-based environment? and (b) How will the student' group projects affect their understanding of lunar related concepts? A mixed-methods approach was used with this semester-long design study to expose how focused project work facilitated spatial understanding. Significant gains were made on lunar-related concepts that had been previously resistant to conceptual change (lunar motion and effect of lunar phase with location change). An implication of this study suggests that technologies (i.e., Stellarium, online blogging with Australia, and Geometer's Sketchpad) facilitated students 'project progress, aided students' understanding of how perspective matters in terms of Earthly sky viewing, and deepened students' understanding on domains that included spatial reasoning., This research concerns a project-based environment created in a graduate course designed for 21st-century science, technology, engineering, and mathematics (STEM) educators. The modeled project-based environment was intentionally designed around the [...]
