Objectives.To identify the virtual reality (VR) interventions used for the lower extremity rehabilitation in stroke population and to explain their underlying training mechanisms using Social Cognitive (SCT) and Motor Learning (MLT) theoretical frameworks.Methods.Medline, Embase, Cinahl, and Cochrane databases were searched up to July 11, 2013. Randomized controlled trials that included a VR intervention for lower extremity rehabilitation in stroke population were included. The Physiotherapy Evidence Database (PEDro) scale was used to assess the quality of the included studies. The underlying training mechanisms involved in each VR intervention were explained according to the principles of SCT (vicarious learning, performance accomplishment, and verbal persuasion) and MLT (focus of attention, order and predictability of practice, augmented feedback, and feedback fading).Results.Eleven studies were included. PEDro scores varied from 3 to 7/10. All studies but one showed significant improvement in outcomes in favour of the VR group (P<0.05). Ten VR interventions followed the principle of performance accomplishment. All the eleven VR interventions directed subject’s attention externally, whereas nine provided training in an unpredictable and variable fashion.Conclusions.The results of this review suggest that VR applications used for lower extremity rehabilitation in stroke population predominantly mediate learning through providing a task-oriented and graduated learning under a variable and unpredictable practice.

Post Therapy

More innovative technologies are used worldwide in patient’s rehabilitation after stroke, as it represents a significant cause of disability. The majority of the studies use a single type of therapy in therapeutic protocols. We aimed to identify if the association of virtual reality (VR) therapy and mirror therapy (MT) exercises have better outcomes in lower extremity rehabilitation in post-stroke patients compared to standard physiotherapy. Fifty-nine inpatients from 76 initially identified were included in the research. One experimental group (n = 31) received VR therapy and MT, while the control group (n = 28) received standard physiotherapy. Each group performed seventy minutes of therapy per day for ten days. Statistical analysis was performed with nonparametric tests. Wilcoxon Signed-Rank test showed that both groups registered significant differences between pre-and post-therapy clinical status for the range of motion and muscle strength (p < 0.001 and Cohen’s d between 0.324 and 0.645). Motor Fugl Meyer Lower Extremity Assessment also suggested significant differences pre-and post-therapy for both groups (p < 0.05 and Cohen’s d 0.254 for the control group and 0.685 for the experimental group). Mann-Whitney results suggested that VR and MT as a therapeutic intervention have better outcomes than standard physiotherapy in range of motion (p < 0.05, Cohen’s d 0.693), muscle strength (p < 0.05, Cohen’s d 0.924), lower extremity functionality (p < 0.05, Cohen’s d 0.984) and postural balance (p < 0.05, Cohen’s d 0.936). Our research suggests that VR therapy associated with MT may successfully substitute classic physiotherapy in lower extremity rehabilitation after stroke.

Virtual reality (VR) is an immersive technology that is increasingly considered for use in the sports media space. With the proliferation of digital media, stakeholders in the sports ecosystem are looking to leverage new technology as part of their distribution strategy. This paper will seek to investigate the potential for virtual reality as a sports broadcasting medium. Through an exploration of various points of view in the field, use cases, and theoretical frameworks, this research will attempt to understand the various barriers to mainstream adoption. This MRP concludes that virtual reality for sport viewing is still in its infancy, but will pervade the market as a complementary broadcasting offering in the future. It will furthermore seek to outline a business model for virtual reality sports to monetize content.

Nonprofit Human Service Organizations

The field of nonprofit studies often assumes that efforts of actors in the nonprofit landscape are beneficial, especially when considering nonprofit human service organizations. However, there are both theoretical and empirical reasons for scholars to adopt a more critical lens when examining these organizations. Taking nonprofit human services organizations as a common setting, the article uses a critical lens to apply classic, “mainstream” theories of the role of heterogeneity in nonprofit sector formation and illuminate risks often neglected in nonprofit human services research. In this way, the article demonstrates that classic social science theories of heterogeneity already offer us the tools we need to critically question dominant assumptions about nonprofit human services provision and challenges the reader to consider why we so rarely use these well-known theoretical frameworks in a critical manner. The article concludes by inviting scholars to utilize additional critical theoretical perspectives in future studies of nonprofit human services.

The Family

Health care professionals have focused for the most part on individuals within families as they provide care in acute care settings. The lack of a theoretical perspective to permit observing the family as a unit with interacting parts has contributed to this practice. This article presents an overview of trends and of four theoretical frameworks that have contributed to family practice and research, both for other disciplines and for nursing. Symbolic interactionism, systems, developmental, and social exchange theories are promising frameworks for considering family relationships now and into the future. The purpose, major concepts, and implications for nursing practice of each theory are presented

Traditional Construction

Occupational Safety and Health Act (1994) and efforts taken to ensure the safety of workers in the construction industry. Despite these, accident rates are still alarming. One of the reasons is due to the weak pedagogy, lack of technology integration, and hazardous learning environment that lead towards low learning performance and practicing safety procedures. This study aims to discover the effectiveness of virtual reality simulation learning environment. Results show that there is a significant difference in trainee's achievements in a traditional construction site visit and virtual construction environment. To conclude, virtual reality learning environment offers effective learning platforms for millennials.Keywords: safety hazards; occupational safety and health; virtual reality;eISSN: 2398-4287 © 2019.

Humans vary greatly in their motor learning abilities, yet little is known about the neural mechanisms that underlie this variability. Recent neuroimaging and electrophysiological studies demonstrate that large-scale neural dynamics inhabit a low-dimensional subspace or manifold, and that learning is constrained by this intrinsic manifold architecture. Here we asked, using functional MRI, whether subject-level differences in neural excursion from manifold structure can explain differences in learning across participants. We had subjects perform a sensorimotor adaptation task in the MRI scanner on two consecutive days, allowing us to assess their learning performance across days, as well as continuously measure brain activity. We find that the overall neural excursion from manifold activity in both cognitive and sensorimotor brain networks is associated with differences in subjects' patterns of learning and relearning across days. These findings suggest that off-manifold activity provides an index of the relative engagement of different neural systems during learning, and that intersubject differences in patterns of learning and relearning across days are related to reconfiguration processes in cognitive and sensorimotor networks during learning.
