Purpose: To assess the feasibility and acceptability of immersive virtual reality for managing anxiety, nausea and vomiting amongst paediatric patients with cancer receiving their first chemotherapy.
Methods: An exploratory randomised control trial supplemented with qualitative interviews was conducted to enrol Chinese paediatric patients receiving their first intravenous chemotherapy. Participants were randomly assigned to intervention (three immersive virtual reality sessions) or control (standard care) groups. The main outcome measures included (1) feasibility parameters; (2) anxiety, nausea and vomiting; and (3) satisfaction with the chemotherapy procedures. Qualitative data were collected by semi-structured individual interviews with patients, parents and nurses.
Results: A total of 19 patients, 19 accompanying parents and 9 nurses were recruited. Results suggested that the intervention was feasible as evidenced by the high consent rate, low withdrawal rate and attrition rate. The intervention group showed significantly better improvement in anxiety at T2 [Hedges' effect size, ES = 1.25, 95% confidence interval (CI): 0.22-2.17)] and T4 [ES = 1.87, 95% CI: 0.72-2.85], as well as greater reduction in acute nausea at T4 [ES = 0.97, 95% CI: 0.02-1.87] than the control group. Qualitative data yielded three categories including positive experiences and perceived benefits of the intervention, and suggested improvements.
Conclusions: This study demonstrated the potential effectiveness, feasibility and acceptability of immersive virtual reality for managing anxiety and acute nausea amongst paediatric patients with cancer receiving their first chemotherapy.

Digital technologies, such as virtual and augmented reality (VR and AR) are mainly used in the preclinical and clinical phases in neurosurgery and orthopedics. In contrast, they are used less frequently in visceral surgery as the intraoperative deformation is challenging for the clinical use. The application of VR is used successfully particularly in education and training.

Background: Alterations to spatial navigation have been suggested by previous studies to represent an early cognitive marker for those with and at risk of Alzheimer's Disease (AD). However, with most of these studies focusing on spatial memory (usage of formed spatial representations), very little is known about the extent to which spatial exploration (process by which spatial representations are formed) may be altered in AD. The aim of this study is to investigate how spatial exploration behavior may be altered in individuals with and at risk of AD, and the extent to which individuals can be classified into their clinical status based on their exploration behavior.

Objectives: The conventional test to detect unilateral spatial neglect (USN) is the Bells Test performed in a paper-and-pencil format. While several studies showed immersive virtual reality (VR) tests may provide greater sensitivity in revealing the presence of USN using visual scanning tasks, none has investigated the Bells Test in VR. This study compares the Bells Test performed in paper-and-pencil format (PP) and in VR in conventional (CVR) and ecological (EVR) format, which differ by the size of the display, in stroke patients.

Background: Training occupational therapy students in manual skills such as goniometry typically requires intensive one on one student teacher interactions and repetitive practice to ensure competency. There is evidence that immersive virtual reality (IVR) supported embodied learning can improve confidence and performance of skills. Embodied learning refers to learner's experience of viewing a simulated body and its properties as if they were the learner's own biological body.

Background: Mental health issues pose a significant challenge for medical providers and the general public. The World Health Organization predicts that by 2030, mental health problems will become the leading cause of global disease burden, highlighting the urgent need for effective mental health interventions. Virtual reality-cognitive behavioral therapy (VR-CBT) has emerged as a promising treatment for neuropsychiatric disorders, offering immersive and engaging therapeutic experiences.
