Although several platforms have nowadays used in clinical practice, contrasting results have been achieved with reduced significant improvements in stroke patients when they experience robotic based therapy. In particular, an improvement of the clinical outcome may be achieved by starting the rehabilitation process almost immediately after the stroke. To address this issue a new robotic system, called “NEUROBike”, has been developed. This approach is based on the hypothesis that a better recovery of the neuro-motor control of the leg could result from an early, intensive and task-oriented rehabilitation therapy. Therefore, the leg manipulation during the acute phase, following joint trajectories comparable with the ones obtained during natural walking, could improve the outcome of the rehabilitation. In this regard, desired trajectories of the end-effector of NEUROBike have been estimated in accordance with data collected from young and elderly people when walking on treadmill in a range of speeds from 0.5 to 1.3 m/s. Moreover, tracking performance of a traditional position control algorithm has been investigated. This paper is aimed at showing the first results obtained during the test of the platform. In the next months NEUROBike will be applied for the first clinical pilot studies.","PeriodicalId":189213,"journal":{"name":"2009 IEEE International Conference on Rehabilitation Robotics","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116022199","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}

Using acceleration feedback and force control strategies, the active BWS system can offload not only partial body weight but also partial body mass (thus the dynamic load) of the patient who is supported by the system. As a result of the reduced mass, the patient can perform training with ease and comfort. Due to the safety requirements, the proposed technology has to be thoroughly investigated through simulation and experiment before a human subject experiment can be safely conducted. The work reported in this paper is such a simulation work. In the simulation the physical human is modeled as a multi-body system with 54 degrees of freedom. The model also predicts physical interaction of the feet with the treadmill using contact dynamics simulation. The simulation results verify that the proposed new active BWS system can dynamically and seamlessly reduce dynamic load of the patient in training.","PeriodicalId":189213,"journal":{"name":"2009 IEEE International Conference on Rehabilitation Robotics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122023554","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, software interfaces which include autonomous intelligent agents have yet to be explored in this context. In this paper we investigate how a narrative storytelling environment which is populated with virtual characters may help children with autism to understand narrative structure and to remember meaningful events within in a story. The behaviours of characters in the narrative storytelling environment are driven by a cognitive agent architecture and, in particular, a specially designed computational autobiographic memory (AM) which allows the virtual characters to remember and express emotional experiences. An application named Virtual Agent Story Interface (VASI) has been developed to visualise the agents' AMs and to help the children to reconstruct their own version of a story. In this paper we describe related research in the area, the overall design rationale of VASI, details of the VASI software design and the preliminary evaluation study.","PeriodicalId":189213,"journal":{"name":"2009 IEEE International Conference on Rehabilitation Robotics","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121651405","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}

Therefore, it is nearly impossible to focus on a stimulus to produce SSVEP activity while simultaneously observing the environment, especially a mobile environment. A compromise has to be found in applications that requires user's attention to the stimulus as well as to the environment (e.g., controlling a wheelchair, moving a robot arm). This paper describes a wearable SSVEP stimulator to keep the stimulus always in the user's field of view. The stimulus is mounted on a transparent visor cap which allows to keep attention to the environment and the stimulus the same time. An experiment with 6 healthy subjects has shown similar results for the visor cap in comparison to a stimulus fixed on a table.","PeriodicalId":189213,"journal":{"name":"2009 IEEE International Conference on Rehabilitation Robotics","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132359356","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, many conventional isokinetic exercise machines cannot be used safely and easily. In this study, we developed an isokinetic and iso-contractile exercise machine, named “MEM-MRB”, using an “MR brake”. This brake includes MR fluid. Because of the rapid response of the MR fluid, the MR brake shows superior response performance compared with conventional brakes. In other words, a simple and safe training machine with accurate rotational speed can be realized with this brake. At the same time, a high-speed (900 [deg/s] at an elbow joint) control was realized with this machine.

It was tested with a robotized Meyra wheelchair at Fondazione Santa Lucia (FSL) in Rome with volunteers presenting different disabilities and we observed that the system seemed to help less persons with better cognitive skills. This seemed to be due to disagreement between the users and the machine when they realized that they were being helped.
