The instrumentation of such a cane device is described and results examining its use and feasibility as a proof of principle are provided in this preliminary study involving five persons with stroke and 5 healthy participants. Average walking speeds with and without the cane are compared between the overground physical environment (PE) and the treadmill-based virtual environment (VE). Gait variability quantified as the % coefficient of variation (CV) for stride duration with and without the cane in the VE is also examined. Furthermore, the vertical loading forces exerted on the cane during level walking in the VE are reported and discussed. Results reveal that walking with the treadmill cane is feasible for use in both healthy and stroke populations. It is evident that people who normally rely on a walking cane benefit more from the instrumented cane than those people who normally walk unaided. This work represents the first instrumented cane for use with a treadmill-based locomotor system.","PeriodicalId":102061,"journal":{"name":"2009 Virtual Rehabilitation International Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116764270","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}

Although presence correlated with immersive tendencies and empathy, empathy and internal locus of control (and not immersive tendencies) were the best predictors for the sense of presence.

We present the design, development and the evaluation of usability of Audio-Based Environments Simulator (AbES) software that enables a blind user to navigate through a virtual representation of a real space in order to train his/her orientation and mobility skills. Our findings indicate that users feel satisfied with the proposed interface, are sure of themselves when interacting with the software, and the incorporated sounds allow them to become correctly oriented within the virtual world that they navigate. AbES is also being used to study changes and adaptations at the level of the brain related to navigation by incorporating the software within a neuroimaging environment. Our results suggest that this kind of virtual environment is highly efficient as a testing, training and rehabilitation platform for learning and navigation.","PeriodicalId":102061,"journal":{"name":"2009 Virtual Rehabilitation International Conference","volume":"114 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113953458","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}

During the chronic phase, many stroke survivors return home where they are cared for by their partner. What was normal before may have become completely impossible or has to be re-learned. Patients will have to find a new balance in their living routine, also redefining their relationship with their spouse and their children, especially those living at home. Depression after stroke affects approximately one third of stroke patients, either as a consequence of the disrupting effects of stroke on the brain, or because the patient is going through a phase of bereavement, through loss of physical and mental abilities, job, income, status, respect, and even relationships. Also, partners of stroke patients run an increased risk of becoming depressed, which is related to depression and a low level of general activities in the patient [1]. Motivating a patient to become more active again is a significant challenge, but has tremendous potential benefits, both for patients as well as their immediate family and caretakers.","PeriodicalId":102061,"journal":{"name":"2009 Virtual Rehabilitation International Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132146520","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}

Schneider","doi":"10.1109/ICVR.2009.5174226","DOIUrl":"https://doi.org/10.1109/ICVR.2009.5174226","url":null,"abstract":"The level of immersion that is induced in an individual can be measured by subjective report, but VE immersion can also affect automatic sensorimotor processes which function below perceptual thresholds. Such sub-threshold effects on central nervous system processing are important to understand for the purposes of shaping VE rehabilitation. This study investigates the effect of dynamic immersive VE on self-motion perception and automatic upper extremity motor response. Subjects viewed either horizontal or vertical sinusoidal linear translation ±1m at 0.25 Hz via a head-mounted display (HMD) while sitting in a stationary motion apparatus. Subjects performed a perceptuomotor task of aligning a handheld object to perceived vertical using their unconstrained arm (i.e. free to move in 6 DOF). Two objects were tested, a joystick and a full glass of water, in counter-balanced order. Results show the majority of subjects perceive self-motion that spatially and temporally agrees with the visually depicted VE motion. This occurs despite the absence of sinusoidally varying changes to gravitoinertial forces, since subjects are not exposed to actual physical motion. Despite only being instructed to orient the handheld object, handheld object kinematics also show automatic motor responses involving object translation. These manual motor responses were dependent on the direction and phase of the visual motion depicted in the VE. Specifically, vertical visual motion induced vertical translation and pitch tilt of the handheld object, while horizontal visual motion induced horizontal translation and roll tilt of the object. Motor responses were significantly greater in subjects who reported compelling self-motion perception. These findings suggest that a representation of net gravitoinertial forces can be derived from the high-fidelity, pictorial and dynamic depth cues visually presented in a VE. Automatic upper extremity manual responses which are controlled by descending central systems and tracts dissociable from lower extremities can be affected by immersion in a VE much like automatic postural behavior has been shown to be. This new evidence supports current efforts to conduct upper extremity rehabilitation in the relative safe and controllable experimental environments that VE technology affords.","PeriodicalId":102061,"journal":{"name":"2009 Virtual Rehabilitation International Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128278041","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}
