ABSTRACT
Purpose@#Awareness of environmental control is considered a major influence on the performance of asthma self-management behaviors that are involved in maintaining effective control of asthma. The aim of this study was to investigate whether immersive virtual reality (VR) education is effective in environmental control education for asthmatic children. @*Methods@#Thirty asthmatic children aged 9 to 13 years with aeroallergen sensitization were enrolled. Environmental control education for asthmatic subjects were performed using either immersive VR (VR group) or conventional leaflets provided by asthma specialists (control group). Five questionnaires, such as awareness of environmental control, memory, assessment of intent to act, satisfaction test, and asthma control test (ACT) questionnaires were used for estimating the effects of education. @*Results@#Awareness of environmental control, memory, and intent to act scores were significantly increased after education in both groups and the scores were maintained high until 4 weeks after education. In both group, ACT scores were maintained high scores before and 4 weeks after education. Satisfaction scores were very high in the VR group. @*Conclusion@#The increased scores in awareness of environmental control and intent to act indicate that the environmental control education using VR is worthy of attention as an effective educational tool for asthma management. Application of further developed techniques, including active environmental intervention by participants in VR, could be applied to effective asthma management.
ABSTRACT
It has been shown that aerobic exercise improves atopic dermatitis (AD), although the mechanism is not clear. Here, we propose a hypothesis that moderate-intensity aerobic exercise improves AD in a mouse model through modulating allergic inflammation. The DNCB-treated mouse model for eczema was divided into 3 groups: (a) not subjected to aerobic exercise, (b) subjected to continuous aerobic exercise and (c) subjected to accumulated aerobic exercise. After given exercise using a treadmill device either 30 min/d or 10 min × 3/day at a speed of 16 m/min, for 9 days, respectively, dermatitis symptom score, thickness of epidermis/dermis and eosinophil infiltration were decreased in the 2 exercise groups compared to the sedentary living group. The serum levels of IgE, MCP-1 and MDC showed a significant decrease both in the continuous or accumulated exercise groups. Moderate-intensity aerobic exercise ameliorates dermatitis symptoms through immune modulation in the DNCB-treated mouse model for eczema.
