This study investigates the effects of conventional versus video-based games exercise training (exergaming) on balance in PBTS. The present study was a randomized controlled trial. The study included 23 PBTS who were randomized to a Video-Based balance exergaming Group (VBG) or Conventional balance exercise training Group (CG). In both groups, the interventions were targeted to the balance function and balance exercise training was administered twice a week for 8 weeks. VBG exercised using selected Nintendo Wii Fit Plus® balance games while CG received a specially designed balance training using conventional physiotherapy methods. The primary outcome was the balance tests (Timed Up and Go and <i>Nintendo® Wii™</i> Center of Gravity: COG), and the secondary outcomes were the functional tests (10-m walking, 2-min walking, 5-step climb/descent/times), and disease effect test (PedsQL Brain Tumor Module). The outcomes were assessed before and after the intervention. At baseline, no significant clinical and outcome assessment differences existed between both groups except for COG (<i>p</i> = 0.0495). After training, overall scores for balance, functional, disease effect tests significantly improved in VBG (<i>p</i> &lt; 0.05) while progress observed in CG was not significant (<i>p</i> &gt; 0.05). Video-based balance exergaming was found effective and more so than conventional balance exercise training in PBTS. Greater effectiveness of exergaming is thought to be due to increased motivation and effort of the children who are more attracted to gaming than conventional exercising. Exergaming could be beneficial both in clinical and home settings with physiotherapist supervision and may reduce the costs of treatment while improving their health-related quality of life.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140569453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Osteoporosis is a systemic skeletal disorder and is among the most prevalent diseases globally, affecting 0.5 billion adults. Despite the fact that the number of people with osteoporosis is similar to, or greater than those diagnosed with cardiovascular disease and dementia, osteoporosis does not receive the same recognition. Worldwide, osteoporosis causes 8.9 million fractures annually; it is associated with substantial pain, suffering, disability and increased mortality. The importance of physical therapy as a rehabilitation strategy to avoid osteoporosis fracture cannot be over-emphasised. However, the main rehabilitation challenges relate to engagement and participation. The use of virtual rehabilitation to address such challenges in the delivery of physical improvement is gaining in popularity. As there currently is a paucity of literature applying virtual rehabilitation to patients with osteoporosis, the authors broadened the search parameters to include articles relating to the virtual rehabilitation of other skeletal disorders (e.g. Ankylosing spondylitis, spinal cord injury, motor rehabilitation, etc.). This systematic review initially identified 130 titles, from which 23 articles (involving 539 participants) met all eligibility and selection criteria. Four groups of devices supporting virtual rehabilitation were identified: a head-mounted display, a balance board, a camera and more specific devices. Each device supported physical improvement (i.e. balance, muscle strength and gait) post-training. This review has shown that: (a) each device allowed improvement with different degrees of immersion, (b) the technology choice is dependent on the care need and (c) virtual rehabilitation can be equivalent to and enhance conventional therapy and potentially increase the patient’s engagement with physical therapy.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140569324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Virtual reality (VR) games are a valuable addition to conventional cognitive rehabilitation as they increase engagement to the therapy through customization, socialization, immersion, and feedback. This review, performed according to PRISMA protocol, addresses the following questions: How VR games have been used for cognitive rehabilitation?, What cognitive domains have been addressed by VR games and in which populations have these games been used?, Which features have been considered to improve engagement in VR games for cognitive rehabilitation?, How is the difficulty adjustment of exercises carried out in VR games for cognitive rehabilitation?. We found 25 scientific works related to these questions, 92% of them treating one cognitive domain at a time, despite the fact that the related literature recognizes the value of training multiple domains simultaneously. Our review indicates that, despite the existence of serious VR games for working memory training, such as those described in Flak et al. (Front Psychol 10:807, 2019. https://doi.org/10.3389/fpsyg.2019.00807), to our knowledge, there are no applications that simultaneously address multiple cognitive domains and incorporate dynamic difficulty adjustment, which are important to ensure ecological validity of therapy and therapy adherence, respectively. In addition, we found that games themselves could be used to monitor the user’s progression. It is also important to determine the impact of multiplayer interactions in the game, test difficulty adjustment approaches that use physiological variables, and define difficulty-skill relationships aligned with the user’s preferences. This paper concludes that the main barriers to implement dynamic difficulty adjustment in VR games for cognitive rehabilitation are: (i) the absence of metrics to estimate when the game offers to the players a challenge adapted their skills, and (ii) the lack of a conceptual framework that integrates relevant theories such as state of flow, cognitive load, cognitive rehabilitation, and feedback systems.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140569452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In two experiments, participants had to grasp a glass and place it to a new position, with either a personal intention (to fill the glass themselves using a bottle) or a social one (to have the glass filled by the human confederate or the virtual agent using the bottle). Experiment 1 showed that the kinematics of the object-directed actions was modulated by the social intention but only when interacting with a human confederate. Experiment 2 showed that the effects of social intention on object-directed actions performance can be improved using feedback-based learning. Specifically, participants proved able to progressively adapt their motor performances as if they were expressing social intention to a virtual confederate as well. These findings emphasize the importance of the modulatory role of social intention on non-verbal motor behaviour, and enrich the understanding of the interaction with virtual agents.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140569320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hall’s proxemics theory, which holds that the distance varies depending on the relationship between people, has been applied when designing VR in such media. However, this concept was usually applied to designs without criticism and without confirming whether proxemic distances established in physical space are equally valid in VR. This study investigated how proxemics in VR activate differently from those in a physical space. We measured the distance and the number of instances of direct contact between people, with 69 participants from Korea and Turkiye. As a result, a proxemics pattern similar to that of a physical space appeared in VR. However, the average distance between participants in the VR was about 160% greater than in the physical space. Also, we could observe direct contact up to 260% more in the VR than in the physical space. We analyzed the collected data using Bayesian ANOVA and t-tests. We could clarify the difference between the two proxemics in physical space and VR, but the reason for the phenomenon has yet to be discovered.

Rehabilitation is an essential component of therapeutic strategy. Virtual reality based rehabilitation (VRBR) is a powerful distraction technique that could be beneficial for chronic neck pain patients. The objective of this systematic review was to analyse the effectiveness of VRBR in chronic neck pain treatment. We followed the PRISMA guidelines and used four databases (CINAHL, Medline (Via PubMed), Scopus and Web of Science) from their inception to August 2023. Eligibility criteria were established using PICOS. Methodological quality was evaluated with the Downs and Black scale and the risk of bias with the Revised Cochrane risk-of-bias tool. The meta-analysis was performed using the RevMan software. Six studies were included in the systematic review and the meta-analysis. We observed significant differences in favour of VRBR for pain intensity (SMD = − 0.46; 95% CI = − 0.74, − 0.19; <em>p</em> = 0.001), disability (MD = − 2.84; 95% CI = − 4.23, − 1.45; <em>p</em> &lt; 0.0001), global perceived effect (MD = 0.49; 95% CI = 0.25, 0.72; <em>p</em> &lt; 0.0001) and patient satisfaction (MD = 0.62; 95% CI = 0.38, 0.86; <em>p</em> &lt; 0.00001). However, at short-term follow-up significant differences were only obtained for disability (MD = − 3.52; 95% CI = − 5.85, − 1.20; <em>p</em> = 0.003). VRBR can significantly improve pain intensity, disability, global perceived effect and patient satisfaction. The small number of articles included in the analysis is a limitation, even considering the good methodological quality of these studies.
