The purpose of this study was to undertake a cross-country comparison of VR/AVG uptake to inform the content of educational interventions designed to promote implementation of these technologies into practice. A cross-sectional online survey that included the Assessing Determinants of Prospective Take-up of Virtual Reality (version 2; ADOPT-VR2) Instrument was conducted in 2014–2015 (Canada) and replicated in 2017–2018 (US). Recruitment took place via convenience and snowball sampling, using email, social media and newsletter postings. Therapists in the US reported greater past experience with, current use of, and intention to use VR/AVGs than did those in Canada. They also rated facilitators more positively and barriers less negatively. Use of customized VR systems was low, with specific system prevalence differing between countries. The most frequently used AVG systems, populations and settings of use, functional goals, predictors of use, learning needs and preferred forms of support were similar between countries. These similarities support the generalizability of educational interventions for both countries. Materials to be developed will focus on non-customized AVG systems. Subsequent work will examine how uptake relates to country-specific health care funding and policies, probe differences in learning needs between therapists with experience using customized versus non-customized VR/AVG systems, and extend the survey to other countries where VR/AVG use is prevalent.","PeriodicalId":179905,"journal":{"name":"2019 International Conference on Virtual Rehabilitation (ICVR)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123239792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such adaptations are designed to measure the same cognitive construct(s) as the original test but may also evaluate interactions between such constructs and other functions (e.g., motor), as occurs in daily life. Here we report on translation of the pen-and-paper Color Trails Test (CTT) to a VR-based head-mount device (HMD) implementation. Trails A is a measure of sustained attention, while Trails B measures divided attention. Participants were twenty-seven young (28.02±3.98 years) and twenty-nine middle-aged (55.41±6.60 years) healthy individuals. For young and middle-aged participants, respectively, mean VR-CTT Trails A completion times were 61.77 and 86.70 sec. Mean VR-CTT Trails B completion times were 113.25 and 154.00 sec, respectively. These completion times were significantly longer than those obtained for the pen-and-paper version (p<.001). The middle-aged group had longer completion times than young adults for both test formats (p<.001), with VR-CTT Trails B separating among the groups better than the corresponding pen-and-paper measure (p<.05). Supporting construct validity, completion times were correlated between pen-and-paper and VR-based versions (Trails A: r=.63; Trails B: r=.60, p’s<.001). VR-CTT motor performance was evaluated by quantifying the deviation of the actual reaching trajectories from the hand trajectories predicted by the minimal jerk model. For both age groups, deviations were greater for Trails B relative to Trails A (p<.001), consistent with a potential effect of divided attention on motor planning and execution. In sum, our VR-based HMD implementation of the CTT assesses similar cognitive constructs to the original pen-and-paper test (construct validity). Further, as suggested by longer completion times and substantial impact of cognitive demands upon motor performance, this VR-CTT affords enhanced ecological validity and added value by capturing cognitive-motor interactions associated with planning and execution of voluntary reaching movements during the task. We believe that such VR-based adaptations lie at the frontier of neuropsychological testing and will ultimately offer novel insights into our understanding of multimodal human function in the real world.","PeriodicalId":179905,"journal":{"name":"2019 International Conference on Virtual Rehabilitation (ICVR)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124760716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paper-and-pencil tasks are still widely used for cognitive rehabilitation despite the proliferation of new computer-based methods, like VR-based simulations of ADL’s. The health professionals’ resistance in adopting new tools might be explained by the small number of validation trials. Studies have established construct validity of VR assessment tools with their paper-and-pencil versions by demonstrating significant associations with their traditional construct-driven measures. However, adaptive rehabilitation tools for intervention are mostly not equivalent to their counterpart paper-and-pencil versions, which makes it difficult to carry out comparative studies. Here we present a 12-session intervention study with 31 stroke survivors who underwent different rehabilitation protocols based on the same content and difficulty adaptation progression framework: 17 performed paper-and-pencil training with the Task Generator and 14 performed VR-based training with the Reh@City. Results have shown that both groups performed at the same level and there was not an effect of the training methodology in overall performance. However, the Reh@City enabled more intensive training, which may translate in more cognitive improvements.","PeriodicalId":179905,"journal":{"name":"2019 International Conference on Virtual Rehabilitation (ICVR)","volume":"87 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126293343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To verify that the movements practiced in virtual reality applications are similar to the movements to be retrained when performing everyday activities, it is important to understand if movements performed in a virtual and a physical environment (real-life) are similar. The aim of this study is to estimate the extent to which unilateral reach to grasp movements performed in a 2D low-cost virtual environment are kinematically similar to movements performed in a comparable physical environment in healthy individuals. Using a cross-sectional design, 12 right-handed, healthy participants performed reaching to grasp movements with the dominant arm in a low cost 2D virtual and a comparable physical environment. Each movement was repeated 20 times in each environment. Arm and trunk kinematics were recorded using the Optotrak motion analysis system (13 markers; 120 Hz) and 3D kinematics were reconstructed. Temporal and spatial characteristics of the endpoint trajectory and arm and trunk movement patterns were compared between environments using ANOVAs. In the virtual environment, movements were slower, more segmented and the endpoint trajectory was straighter. Ranges of motion of arm and trunk movements did not differ between environments. When using 2D virtual environments for upper limb rehabilitation, differences in movement performance between virtual and physical environments should be taken into account.","PeriodicalId":179905,"journal":{"name":"2019 International Conference on Virtual Rehabilitation (ICVR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128601280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, since motor recovery is related to exercise intensity and task difficulty, it is important to determine whether these factors are considered in VR applications applied in different centers for patients with different motor impairment levels. We define exercise intensity as the total number of movement repetitions divided by the total minutes in active therapy.The main objective of this study was to determine the training intensity of a clinically-applied treatment program using VR in 3 centers involved in a multi-site study. Our secondary objective was to determine if training intensity differed among patients with different levels of UL sensorimotor impairment.Patients with sub-acute unilateral stroke in the middle cerebral artery area (<6 mo post-stroke) with Fugl-Meyer Assessment (FMA-UL) scores ranging from 14–57, completed 10 50-minute UL training sessions with a VR rehabilitation application over 2 weeks, in rehabilitation centers located in 3 countries. Total training time (minutes), total number of movement repetitions, and success rates were extracted from game activity logs. Intensity was calculated for each game for each participant, related to UL impairment and compared between centers.Exercise intensity was higher in one of the 3 centers (p<0.01). Participants had most difficulty with the games involving bilateral coordination and lateral reaching. Participants with higher FMA-UL scores had longer total training times (r = 0.40, p = 0.03) and started the training earlier within the subacute phase (r = −0.38, p = 0.04). Participants who used the VR system later in the subacute phase trained at a higher intensity than those who started earlier (r = 0.43, p = 0.02). However, their level of training intensity was not related to UL impairment.The level of intensity attained with this training program was much higher than that reported in current stroke therapy practice. Despite different training centers, therapists progressed patients through the training program using similar training principles. Therefore, VR rehabilitation systems can be used to deliver intensive exercise programs in a standardized way and can be tailored to individual impairment levels.","PeriodicalId":179905,"journal":{"name":"2019 International Conference on Virtual Rehabilitation (ICVR)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121268752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
