Joint-level augmentation treatment, grounded in referent control theory, prescribes insertion of error at the joint level for inducing a dynamic re-mapping of muscle-leve control mechanisms. We hypothesize that this will lead to an increase in the control range of the joint and consequently to improved performance of voluntary motion. In the current presentation we describe a system harnessing virtual reality developed for upper-limb training based on joint level error augmentation. The system comprises three components, a passive arm rest supporting the arm against gravity, a Kinect motion tracking system, and a virtual-reality training environment. The visualization of the entire arm is a critical system component which should invoke a high degree of presence. For the method to be effective, the participant should accept the visualized arm position as representing his/her actual arm location, despite conflicting input from his/her proprioception. A pilot test is currently under way for assessing the method’s effectiveness.","PeriodicalId":179905,"journal":{"name":"2019 International Conference on Virtual Rehabilitation (ICVR)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122960685","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}

Patients who experience symptoms or a fall within a certain environment are likely to develop fear of that situation. It has been suggested that multisensory integration should be addressed in conditions as close as possible to real-life situations, but these are often challenging to replicate in the clinical setting. Virtual reality (VR) can provide a non-threatening method for patients to practice multisensory integration in a functional context. Advances in technology make Head Mounted Displays (HMDs) accessible and affordable in the clinic. We developed a VR HMD application that allows patients to practice contextual sensory integration (C.S.I) while sitting, standing, turning or stepping within diverse scenes. This application can become an integral part of vestibular rehabilitation. For successful implementation, usability is critical. In this pilot, usability and preliminary outcomes were tested in a mixed-methods descriptive study. Six physical therapists in a Vestibular Rehabilitation Clinic treated 12 patients with peripheral or central vestibular disorders. Therapists viewed the system as a bridge for a functional carry over from the clinic to the outside world. While they reported challenges in operating the technology within the clinical time constraints, they liked the ability to gradually introduce a challenging sensory stimulus and bring reality to the clinic. Several patients dropped out prior to completing training. Nine out of 12 patients who completed training thus far improved their disability score, 9 improved their visual vertigo and 10 improved their balance confidence following training with the app. Recommendation for future research and clinical implementation are discussed.","PeriodicalId":179905,"journal":{"name":"2019 International Conference on Virtual Rehabilitation (ICVR)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130195474","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}

The present study focuses on kinematic and dynamic adaptation and post-adaptation effects of lower limb segment coordination, during and after a 15 N tensile force exposure by presenting two representations of 3D coordination - planar and phase diagrams. One chronic stroke subject (73 y.o., 8 months post-stroke, RH) and one age-matched control subject (71 y.o, RH) walked on a self-paced treadmill in a virtual environment holding a robot-controlled haptic leash. The paradigm consisted of a 30 s pre-force baseline epoch, followed by a 60 s tensile force and a 60 s post-force epoch. Both the chronic stroke and control subject showed evidence of changes in bilateral intersegmental coordination of the lower limb to accompany gait speed increases during force and post-force epochs. In particular, both subjects increased dorsiflexion of the non-dominant leg during and after the 15 N force exposure. Changes in limb segment coordination also corresponded to bilateral increases in 3D intersegmental trajectory areas. While there was no evidence of increased symmetry based on left and right leg plane comparisons, slight increases in angular velocity were noted just prior to and during the swing phase of the paretic leg during force and post-force epochs. These findings were further substantiated by Sobolev norms which increased bilaterally and proportionally for force and post-force epochs. Adaptation and post-adaptation effects seen in bilateral lower limb coordination when haptic forces were present and released suggest proportional increases in the kinematic and dynamic outcomes. Further investigation involving a wider range of chronic stroke functional levels should be conducted.","PeriodicalId":179905,"journal":{"name":"2019 International Conference on Virtual Rehabilitation (ICVR)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127932612","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}
