The test consists of a virtual winding path along which participants must navigate (or be navigated by an experimenter) as they name objects encountered along the way. There are 4 VR task conditions, obtained by crossing the factors array complexity (simple, complex) and driver (participant, experimenter). Participants performed the VR task, a real-life wheelchair navigation task, and a battery of tests assessing arousal, visual attention under secondary task demands, and neglect. The VR test showed sensitivity to both array complexity and driver, with best performance occurring in the experimenter-navigated, simple array condition. The VR test also showed high correlations with the wheelchair navigation test, and these correlations were in many instances higher than those between traditional clinical neglect tests and the wheelchair navigation task. Moreover, the VR test detected lateralized attention deficits in participants whose performance was within the normal range on other neglect tests. We conclude that the VR task is sensitive to factors likely to affect the severity of neglect in the daily environment, and shows promise as an efficient, easily administered measure of real-life wheelchair navigation","PeriodicalId":140793,"journal":{"name":"2006 International Workshop on Virtual Rehabilitation","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126366455","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}

Virtual realty (VR) provides a unique environment where the presentation of stimuli can be systematically controlled to enable an optimal level of challenge by progressing task difficulty as performance improves. We describe four VR tasks that were developed and tested to improve skilled arm and hand movements in individuals with hemiparesis. Two participants post-stroke with different levels of motor severity attended 12 training sessions lasting 1 to 2 hours each over a 3-week period. Behavioral measures and questionnaires were administered pre-, mid-, and post-training. The less impaired participant averaged more time on task, practiced a greater number of blocks per session, and progressed at a faster rate over sessions than the more impaired participant. Differences in functional outcomes for these two cases can be explained in part by which tasks were practiced, the level of task difficulty applied during practice, and the amount of repetition included in practice","PeriodicalId":140793,"journal":{"name":"2006 International Workshop on Virtual Rehabilitation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120957822","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}

Remote assessment was compared to co-located assessment for five evaluation instruments. Developing teleassessment methods is important for delivering rehabilitation services to those whose access is limited by distance or the ability to travel to comprehensive rehabilitation clinics. The five clinical measures utilized were joint range of motion (ROM), manual muscle test (MMT), Berg sit-to-stand, Berg forward reach and the timed up and go (TUG). Co-located and remote rooms were in the same building, connected by broadband video and audio. Ten subjects without impairments participated, but were given simulated impairments to mimic the patient population commonly seen in rehabilitation clinics. One therapist performed all co-located testing while another performed all remote assessments. The two therapists were blinded to each others' test results. Measurements followed standard clinical methods. Data were analyzed using repeated measures ANOVA and paired t-tests. Results: No significant differences were found between co-located and remote assessments, but the power to detect small differences was low. Remote ROM tests using snapshots and a virtual goniometer were preferred. A digital dynamometer added no additional information to a visually-based remote MMT assessment. Remote application of several clinical test instruments was shown to be technically feasible and there are advantages to particular methods for conducting remote assessments. A clinical study with patients is needed to determine efficacy, reliability and validity of remote assessment","PeriodicalId":140793,"journal":{"name":"2006 International Workshop on Virtual Rehabilitation","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122113334","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}

If surgery is needed, the treatment involves decompression of the median nerve followed sometimes by musculo-skeletal outpatient rehabilitation. This paper presents results of pilot clinical trials in which the Rutgers Masters II haptic glove was tested on five subjects, who were two weeks post hand surgery. Subjects trained for 13 sessions, 30 minutes per session, three sessions per week, and had no conventional outpatient therapy. Computerized measures of performance showed group effects in hand mechanical energy (1,200% for the virtual ball squeezing and Digikey exercises and 600% for the power putty). Improvement in their hand function was also observed (a 38% reduction in virtual pegboard errors, and 70% fewer virtual hand ball errors). Clinical strength measures showed increases in grip (by up to 150%) and key pinch (up to 46%) strength in three of the subjects, while two subjects had decreased strength following the study. However, all five subjects improved in their tip pinch strength of their affected hand (between 20% and 267%). When asked whether they would recommend the VR exercises to others, four subjects very strongly agreed and one strongly agreed that they would","PeriodicalId":140793,"journal":{"name":"2006 International Workshop on Virtual Rehabilitation","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132785614","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}

People who have had a stroke often suffer from impairments in executive functions which have implications for their ability to return to full participation in their everyday activities and occupations. During the rehabilitation process clinicians seek opportunities, which will not be time consuming or expensive, to engage patients in complex functional activities, in order to train and improve deficits in executive functions. One solution for this is using functional virtual environments. The objectives of this study were to examine the feasibility of using a virtual supermarket to assess and treat executive function deficits for people who have had a stroke, and to explore the relationships between performance within the virtual supermarket and executive functions. The virtual supermarket used in this study runs on a desktop computer and is easy to operate in typical clinical settings. Twenty-six people, aged 31 to 65 years, who had a stroke participated in the study. Participants were tested with the virtual supermarket where they were asked to buy seven products from a prepared list. Each participant was also tested with the behavioral assessment of the dysexecutive syndrome. The results showed a large variance of performance within the virtual supermarket. In addition, moderate relationships were found between performance within the virtual supermarket and executive functions. The results point to the potential of the virtual supermarket to be used as an assessment and training tool for executive functions of people who have had a stroke","PeriodicalId":140793,"journal":{"name":"2006 International Workshop on Virtual Rehabilitation","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132971907","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}
