Feasibility Of Virtual Reality Research Articles

Research on user response in virtual reality environment based on visualization and clustering

As the feasibility of virtual reality (VR) therapies is gradually being validated, understanding users' physiological and emotional responses to different VR environments is crucial for optimizing VR experiences and improving user engagement. This study aims to introduce machine learning models to analyze user responses to VR environments and identify user groups with similar physiological and emotional characteristics. This study employs visualization tools and clustering models to explore the role of various factors in shaping user experience. K-Means modeling helps the research team understand users' physiological and emotional responses to VR environments. The Principal Component Analysis (PCA) dimensionality reduction algorithm makes the model visualization easier to understand and implement. This study is conducted on a virtual reality experience dataset and produced many nuanced users experience results. The results of the experiments show that there is an apparent disparity in the experience of VR among users of different age groups. It also shows that different user groups have different levels of suitability for VR. Targeted improvements to VR can provide suggestions for people with different needs. This study has significant implications for analyzing and understanding the emotional responses and preferences of VR users and driving the personalization of VR products.

A Rapid Review of the Role of Virtual Reality in Care Delivery of Palliative Care and Hospice.

Virtual reality (VR) is an emerging technology that can provide a nonpharmacological approach to symptom management for those with serious illnesses. The VR platform offers a unique perspective to connect patients with places and experiences they might otherwise miss. This rapid review aims to present the current literature on the uses and benefits of VR for palliative care and hospice patients. Through a systematic process, we identified 14 articles published between 2018 and 2023 that used VR as an interventional strategy for symptom management. The VR equipment includes a head-mounted display, such as the Oculus Go, and sometimes requires hand controllers or joysticks. Virtual reality software was contained exclusively in the head-mounted displays or required a laptop. Nature scenes, memorable locations, and the solar system are examples of options patients could select for the VR experience. Assessments of the intervention were measured before, during, after, and several hours afterward to evaluate benefits and potential adverse effects. Pain was the predominant symptom assessed in the studies. Overall, most of the studies focused on establishing the safety, efficacy, and feasibility of VR using a single-arm interventional method. Future research should implement randomized controlled trials, increase sample size, and expand to pediatric populations.

Nature-Based Virtual Reality Feasibility and Acceptability Pilot for Caregiver Respite.

Home-based informal caregivers (CGs), such as the family members and friends of cancer patients, often suffer averse emotional symptoms, such as anxiety and depression, due to the burden associated with providing care. The natural environment has been valued as a healing sanctuary for easing emotional pain, promoting calmness, relaxation, and restoration. The use of virtual reality (VR) nature experiences offers an alternative option to CGs to manage emotional symptoms and improve their quality of life. The aim of this mixed-method pilot was to evaluate the feasibility and acceptability of a nature-based VR experience for home-based CGs. Nine informal CGs participated in a 10 min nature-based VR session and completed feasibility, acceptability, and VR symptom measures in the laboratory. Semi-structured interviews with five of the CGs provided qualitative data regarding their experiences with VR. The CGs (mean age 64.78 years) were mostly female (n = 7). Our analysis showed high feasibility (15.11 ± 1.76; range 0-16) and acceptability (15.44 ± 1.33; range 0-16), as well as low VR Symptoms (1.56 ± 1.33; range 0-27). Participants primarily expressed positive perceptions regarding VR feasibility and acceptability during interviews. Our findings show promise for the use of VR nature experiences. In the next phase of the study, the intervention will be tested on home-based informal CGs of patients at end of life.

Feasibility of virtual reality and treadmill training in traumatic brain injury: a randomized controlled pilot trial

ABSTRACT Objective To evaluate the safety and efficacy of treadmill training with virtual reality compared to treadmill training alone and standard of care balance and mobility treatment in chronic traumatic brain injury (TBI). Participants and Design Thirty-one individuals with chronic TBI with self-reported and objective balance deficits participated in a 4-week 12 session intervention of treadmill training with virtual reality, treadmill training alone, or standard of care overground therapy. Outcome Measures Primary measures included recruitment and enrollment rates, retention, tolerance to intervention, completeness of outcome measures, and adverse events. Secondary measures included the Community Balance and Mobility Scale, 10 Meter Walk Test, 6 Minute Walk Test, and Timed Up and Go. Results No serious adverse events were reported. All participants completed all training sessions and assessments at all time points. Recruitment, enrollment, and retention rates were high. All groups showed a trend toward improvement in all balance and mobility measures following treatment. Conclusion Virtual reality and treadmill training are safe and feasibile for individuals with TBI. Participants show improvements on balance and mobility measures following a 4-week intervention. Future research is needed to evaluate the efficacy of this intervention compared to other modes of balance and mobility training.

Feasibility of virtual reality based training for optimising COVID-19 case handling in Uganda

BackgroundEpidemics and pandemics are causing high morbidity and mortality on a still-evolving scale exemplified by the COVID-19 pandemic. Infection prevention and control (IPC) training for frontline health workers is thus essential. However, classroom or hospital ward-based training portends an infection risk due to the in-person interaction of participants. We explored the use of Virtual Reality (VR) simulations for frontline health worker training since it trains participants without exposing them to infections that would arise from in-person training. It does away with the requirement for expensive personal protective equipment (PPE) that has been in acute shortage and improves learning, retention, and recall. This represents the first attempt in deploying VR-based pedagogy in a Ugandan medical education context.MethodsWe used animated VR-based simulations of bedside and ward-based training scenarios for frontline health workers. The training covered the donning and doffing of PPE, case management of COVID-19 infected individuals, and hand hygiene. It used VR headsets to actualize an immersive experience, via a hybrid of fully-interactive VR and 360° videos. The level of knowledge acquisition between individuals trained using this method was compared to similar cohorts previously trained in a classroom setting. That evaluation was supplemented by a qualitative assessment based on feedback from participants about their experience.ResultsThe effort resulted in a COVID-19 IPC curriculum adapted into VR, corresponding VR content, and a pioneer cohort of VR trained frontline health workers. The formalized comparison with classroom-trained cohorts showed relatively better outcomes by way of skills acquired, speed of learning, and rates of information retention (P-value = 4.0e-09). In the qualitative assessment, 90% of the participants rated the method as very good, 58.1% strongly agreed that the activities met the course objectives, and 97.7% strongly indicated willingness to refer the course to colleagues.ConclusionVR-based COVID-19 IPC training is feasible, effective and achieves enhanced learning while protecting participants from infections within a pandemic setting in Uganda. It is a delivery medium transferable to the contexts of other highly infectious diseases.

Virtual Reality in the Management of Chronic Low Back Pain: A Scoping Review.

Virtual reality (VR) is a burgeoning treatment option for chronic pain. Its use has been heterogenous in the literature. This scoping review assesses the current literature for the use of VR in the treatment of chronic low back pain (CLBP). The following themes were identified by the analysis: safety and feasibility of VR, quality of life associated with VR treatment for CLBP, efficacy of VR to treat CLBP, and efficacy of VR to treat functional changes associated with CLBP. Gaps were identified after analysis of the extant literature. Although the nascent research uncovered in this scoping review found good evidence for safety and tolerability of VR, more studies of safety, acceptance, and satisfaction are recommended including focused studies of spinal pain risks specific to use of VR. Overall, the methodological quality of studies reviewed in this scoping review was poor and outcomes were limited to short-term posttreatment outcomes.

Virtual Reality in the Preoperative Planning of Adult Aortic Surgery: A Feasibility Study.

Background: Complex aortic anatomy needs careful preoperative planning in which a patient-tailored approach with novel immersive techniques could serve as a valuable addition to current preoperative imaging. This pilot study aimed to investigate the technical feasibility of virtual reality (VR) as an additional imaging tool for preoperative planning in ascending aortic surgery. Methods: Ten cardiothoracic surgeons were presented with six patients who had each undergone a recent repair of the ascending aorta. Two-dimensional computed tomography images of each patient were assessed prior to the VR session. After three-dimensional (3D) VR rendering and 3D segmentation of the ascending aorta and aortic arch, the reconstructions were analyzed by each surgeon in VR via a head-mounted display. Each cardiothoracic surgeon completed a questionnaire after each planning procedure. The results of their assessments were compared to the performed operations. The primary endpoint of the present study was a change of surgical approach from open to clamped distal anastomosis, and vice versa. Results: Compared with conventional imaging, 80% of surgeons found that VR prepared them better for surgery. In 33% of cases (two out of six), the preoperative decision was adjusted due to the 3D VR-based evaluation of the anatomy. Surgeons rated CardioVR usefulness, user-friendliness, and satisfaction with median scores of 3.8 (IQR: 3.5–4.1), 4.2 (IQR: 3.8–4.6,) and 4.1 (IQR: 3.8–4.7) on a five-point Likert scale, respectively. Conclusions: Three-dimensional VR imaging was associated with improved anatomical understanding among surgeons and could be helpful in the future preoperative planning of ascending aortic surgery.

Use of Virtual Reality for Pediatric Cardiac Critical Care Simulation.

Simulation is a key component of training in the pediatric cardiac intensive care unit (CICU), a complex environment that lends itself to virtual reality (VR)-based simulations. However, VR has not been previously described for this purpose. Two simulations were developed to test the use of VR in simulating pediatric CICU clinical scenarios, one simulating junctional ectopic tachycardia and low cardiac output syndrome, and the other simulating acute respiratory failure in a patient with suspected coronavirus disease 2019. Six attending pediatric cardiac critical care physicians were recruited to participate in the simulations as a pilot test of VR’s feasibility for educational and practice improvement efforts in this highly specialized clinical environment. All participants successfully navigated the VR environment and met the critical endpoints of the two clinical scenarios. Qualitative feedback was overall positive with some specific critiques regarding limited realism in some mechanical aspects of the simulation. This is the first described use of VR in pediatric cardiac critical care simulation.

Assessment of virtual reality as an anxiety and disgust provoking tool: The use of VR exposure in individuals with high contamination fear

Preliminary studies have provided promising results on the feasibility of virtual reality (VR) interventions for Obsessive-Compulsive Disorder. The present study investigated whether VR scenarios that were developed for contamination concerns evoke anxiety, disgust, and the urge to wash in individuals with high (n = 33) and low (n = 33) contamination fear. In addition, the feasibility of VR exposure in inducing disgust was examined through testing the mediator role of disgust in the relationship between contamination anxiety and the urge to wash. Participants were immersed in virtual scenarios with varying degrees of dirtiness and rated their level of anxiety, disgust, and the urge to wash after performing the virtual tasks. Data were collected between September and December 2019. The participants with high contamination fear reported higher contamination-related ratings than those with low contamination fear. The significant main effect of dirtiness indicated that anxiety and disgust levels increased with increasing overall dirtiness of the virtual scenarios in both high and low contamination fear groups. Moreover, disgust elicited by VR mediated the relationship between contamination fear and the urge to wash. The findings demonstrated the feasibility of VR in eliciting emotional responses that are necessary for conducting exposure in individuals with high contamination fear. In conclusion, VR can be used as an alternative exposure tool in the treatment of contamination-based OCD.

The Feasibility of Virtual Reality and Student-Led Simulation Training as Methods of Lumbar Puncture Instruction.

There is limited data assessing simulation and virtual reality training as a standardized tool in medical education. This feasibility study aimed to evaluate the effectiveness of virtual reality training and a student-led simulation module in preparing medical students to perform a lumbar puncture. Twenty-five medical students completed a pre-intervention survey, and a baseline video recorded lumbar puncture procedure on a task trainer. Students were randomly distributed into the virtual reality group, or the curriculum's standard student-led procedural instruction group. Participants were then given 45min to practice the lumbar puncture procedure. After the intervention, all participants were video recorded again as they performed a post-intervention lumbar puncture and completed a post-intervention survey. Pre- and post-intervention videos were scored using a critical action checklist in conjunction with time needed to complete the procedure to evaluate proficiency. At baseline, there were no major statistically significant differences between groups. Assessing overall post-intervention performance, both groups showed improvement in aggregate score (p < 0.001) and time required to complete (p = 0.002) the lumbar puncture. Following interventions, the student-led group improved over the virtual reality group in a variety of metrics. The student-led group increased their aggregate score by 3.49 and decreased their time to completion by 34s over the VR group when controlling for baseline measures. Both virtual reality and student-led simulation training were useful training modalities, with hands-on simulation showing better results versus virtual reality training in this setting.

Bringing the outside in: The feasibility of virtual reality with people with dementia in an inpatient psychiatric care setting.

Emerging research supports virtual reality use with people with dementia in the community, but is limited to this area, warranting further investigation in different care settings. The feasibility of virtual reality within an inpatient psychiatric care setting was therefore explored.Research design and methods: Eight people with dementia and 16 caregivers were recruited in January and February 2018 from a UK hospital specialising in progressive neurological conditions. A mixed methods design measured affect and behaviour using the Observed Emotion Rating Scale, Overt Aggression Scale-Modified for Neurorehabilitation and St Andrew's Sexual Behaviour Assessment. Thematic analysis was conducted following semi-structured interviews. Caregivers who worked at the hospital supported people with dementia throughout the process and were interviewed for their views on Head Mounted Display-Virtual Reality (HMD-VR) use with people with dementia. HMD-VR was tried and accepted by people with dementia. Participants viewed HMD-VR positively as a 'change in environment' and would use it again. People with dementia experienced more pleasure during and after HMD-VR compared to before exposure, as well as increased alertness after. Three core themes emerged: 'Virtual Reality Experiences', 'Impact of Virtual Reality' and 'Experiences within the Virtual Environment'. Caregivers discussed preconceptions about virtual reality use and how these changed.Discussion and implications: This is the first study to explore the feasibility of HMD-VR with people with mild to moderately severe dementia in hospital and found that overall HMD-VR is viable. Findings evidence the clinical feasibility of HMD-VR implementation in this environment and inform future research.

Effectiveness and feasibility of virtual reality and gaming system use at home by older adults for enabling physical activity to improve health-related domains: a systematic review

use of virtual reality and commercial gaming systems (VR/gaming) at home by older adults is receiving attention as a means of enabling physical activity. to summarise evidence for the effectiveness and feasibility of VR/gaming system utilisation by older adults at home for enabling physical activity to improve impairments, activity limitations or participation. a systematic review searching 12 electronic databases from 1 January 2000-10 July 2012 using key search terms. Two independent reviewers screened yield articles using pre-determined selection criteria, extracted data using customised forms and applied the Cochrane Collaboration Risk of Bias Tool and the Downs and Black Checklist to rate study quality. fourteen studies investigating the effects of VR/gaming system use by healthy older adults and people with neurological conditions on activity limitations, body functions and physical impairments and cognitive and emotional well-being met the selection criteria. Study quality ratings were low and, therefore, evidence was not strong enough to conclude that interventions were effective. Feasibility was inconsistently reported in studies. Where feasibility was discussed, strong retention (≥70%) and adherence (≥64%) was reported. Initial assistance to use the technologies, and the need for monitoring exertion, aggravation of musculoskeletal symptoms and falls risk were reported. existing evidence to support the feasibility and effectiveness VR/gaming systems use by older adults at home to enable physical activity to address impairments, activity limitations and participation is weak with a high risk of bias. The findings of this review may inform future, more rigorous research.

"Wii-Hab" in critically ill children: A pilot trial

To evaluate the safety and feasibility of virtual reality (VR) exercise as a novel acute rehabilitation intervention in a Pediatric Critical Care Unit (PCCU) setting. Children aged 3-18 years with an anticipated PCCU stay > 48 hours, and baseline normal to moderate cognitive and functional disability were eligible. Exclusion criteria included: anticipated death, physical inability, or a contraindication to mobilization. Nintendo Wii™ Boxing was prescribed for a minimum of 10 minutes twice a day for 2 days. Primary outcomes were feasibility and safety. Of 21 eligible patients, 12 (57.1%) were enrolled and 8 completed the study. 41.7% (5/12) were males, and the median age was 11 (3,16) years. Four of the 8 participants who received the intervention were mechanically ventilated during Wii™ play. Participants used the Wii™ a median of 2 times (1,5) over the 2-day intervention period, for a median total duration of 54.5 (15, 224) minutes. There were no adverse events attributable to the intervention. Upper limb activity during Wii™ was significantly greater than the average daily activity (p=0.049). Grip strength did not change significantly from baseline (p=0.20). While the results of this pilot trial suggest that VR exercise may be safely applied in a subset of critically ill children, we observed several threats to its feasibility in this population.

Virtual Reality Promotes Visual and Cognitive Function in Rehabilitation

The purpose of this study is to evaluate the effectiveness of virtual reality (VR) in cognitive and perceptual dysfunction. Patients who have suffered cerebro-vascular accidents may exhibit visual field and auditory processing deficits, which may pose a challenge for clinicians in the rehabilitation setting. Visual neglect and auditory processing can greatly interfere with a person's ability to perform activities of daily living. These can include reading, writing, dressing, self care activities, communicating, and establishing eye contact during conversational exchanges. Occupational therapists and speech-language pathologists coordinate their treatment goals to address these cognitive and visual perceptual deficits for improved communication skills and performance of daily functional activities. Our focus is to demonstrate how VR can be used in conjunction with traditional therapeutic techniques to facilitate a patient's ability to follow multi-unit commands and increase visual attention to the affected side. The VR technology used in this particular procedure is nonimmersive, which allows for full body movement and immediate feedback. Future efforts to determine the feasibility of VR in other aspects of rehabilitation are currently being explored.
