Rehabilitation of hand function in patients with upper limb impairment is often de-prioritized to allow for an emphasis on practicing activities necessary for a safe discharge to the home, such as walking and bed mobility. This case study describes a patient with slow recovering hand motor function (hand sub-section of Fugl-Meyer examination score = 2 on post-stroke day 37) following a stroke. The patient received an intensive eight-session intervention that focused on the recovery of finger extension, finger individuation and pinch-grasp force modulation as well as the recovery of proximal upper extremity movement. Over the eight sessions, the patient demonstrated a dramatic increase in hand function and a corresponding expansion of the cortical motor map area representing several key muscles of the paretic hand. Recovery of hand function and motor map expansion continued after discharge through the three-month retention testing. Gains in motor control transferred to clinically meaningful hand function measured at the activity level.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"123 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123903514","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}

This initial study tested the feasibility of training individuals with severe hemiparesis using virtual reality (VR) based mirrored feedback and pinch force modulation tasks. The results demonstrated that the simulations were well tolerated early after stroke. Priming effects of the mirror tasks were suggested by increased maximal pinch force immediately after training. Furthermore, despite having no clinically observable movement distally, the subjects were able to consciously activate their muscles as shown by force traces and EMG recorded during the pinch trace task. Motor learning was also suggested by the decrease in Root Mean Square Error (RMSE) during this task. Lastly the benefits of using objective, technology based measurement tools was demonstrated by the ability of the force sensor to detect small changes in force production that could not be measured with a clinical scale of impairment.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127384022","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}

Specifically, we compared the effectiveness of augmented information feedback provided per training trial either visually, haptically or visual-haptically to the non-augmented condition, where no on-line feedback on task performance was afforded during training sessions. Surprisingly, the non-augmented training group was in general as successful in the long-term learning of a rowing skill as the augmented groups and according to some measures even superior to them. Our results also highlight important differences in the course of learning and skill representation upon different feedback conditions provided during training and may provide useful insights to the optimization for both sport and rehabilitation training protocols in VR.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115766889","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}

Two of these are equipment costs and the VR interface. In order to address these hurdles, a stepping game was developed from the ground-up using simple source code - C# and WPF and the Microsoft Windows 7 (WinT) Operating System (OS). Using a managed-open-source perspective [2] and sharing the source code enables the rehabilitation community to customized their game for deployment on a desktop or laptop running the Win7 system while limiting costs. The game is built in the native Win7 environment and is coded for development by a beginner programmer. It also allows for the wider open-source developer community to take the programming and application further than would otherwise be possible.

This was accompanied by similar changes in stride length, which increased as much as 15% when walking with the haptic force in the stroke group. While double and single limb support times showed some signs of reduction relative to the pre-force baseline, further investigation is needed to determine whether there are proportional changes in double limb support durations relative to the paretic or non-paretic limb.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"289 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116176102","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 growth was allowed by inducing the need of patient - environment interaction and efforts to achieve goals. Possibility to carry out the therapy at much higher and more accurate doses, instead of manual therapy, represents another benefit to the research. We can achieve more frequent and more intense therapies without consequences of fatigue, only by adjusting to individual patients needs, with help of robotic devices. Although robotic research continues to grow despite of increasing number of patients per one physical therapist, it still saves time. Use of virtual reality as a new kind of neurorehabilitation promises to improve the traditional health care. Nevertheless, best results are achieved in combination with robotic and traditional therapy. The aim of our study is to analyse effect of cognitive therapy by using virtual reality on upper limp mobility in postacute stroke patients.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123606517","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 there is still a need for an accurate quantitative grading system that is easy to use, inexpensive and has low inter-observer variability. This work presents such a grading system based on the newly released Kinect for Windows v2 and accompanying SDK 2.0. This new system automatically detects facial landmarks and is designed to compute and grade resting facial symmetry and the extent of facial paralysis for several voluntary movements. The system also offers the option to report grading according to three widely used traditional grading systems. The system developed so far shows promising results and is a work in progress. More facial landmarks and more voluntary movements are being added to have a comprehensive quantitative grading tool which can be widely used by clinicians. With further work, it can be extended to become a virtual rehabilitation tool for facial paralysis.","PeriodicalId":194703,"journal":{"name":"2015 International Conference on Virtual Rehabilitation (ICVR)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128624279","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}
