Limb Rehabilitation

Nonlinear optimisation-based search algorithms have been developed for the precise stimulation of muscles in the wrist and hand, to enable stroke patients to attain predefined gestures. These have been integrated in a system comprising a 40 element surface electrode array that is placed on the forearm, an electrogoniometer and data glove supplying position data from 16 joint angles, and custom signal generation and switching hardware to route the electrical stimulation to individual array elements. The technology will be integrated in a upper limb rehabilitation system currently undergoing clinical trials to increase their ability to perform functional tasks requiring fine hand and finger movement. Initial performance results from unimpaired subjects show the successful reproduction of six reference hand postures using the system.

The purpose of the present study is to assess the influence of auditory and haptic signals on the manipulation performance in a virtual reality-based hand rehabilitation system. A personal computer, a tracker, and a data glove were included in this system. Three-dimensional virtual environments were developed. Forty volunteers were recruited to participate in a pick-and-place procedure, with three levels of difficulty and four feedback modes. Task time and collision frequency were the parameters used to evaluate their manipulation performance. It can be concluded that the haptics is a significant signal for improving a subject's performance at the high difficulty level.

The purpose of the present study is to assess the effect of an auxiliary lateral image and display devices on manipulation performance in a virtual reality-based hand rehabilitation system. The system consists of a personal computer, a tracker, a data glove, and a display device. For this study, a projector, a monitor, and a head-mounted display were respectively used as the display devices to present three-dimensional virtual environments. Twelve volunteers were recruited to take a pick-and-place procedure at different levels of difficulty. Task time and collision frequency were the parameters used to evaluate the manipulation performance. It was found that the presence of an auxiliary lateral image was a significant factor only for the performance of the projector group and the monitor group. In addition, no statistically significant difference was found in the comparison between the projector group and the monitor group.

The Brazilian Symposium on Virtual and Augmented Reality (SVR) celebrated its 10th edition in 2008, in the city of João Pessoa. During these last 10 years, SVR has earned its space and magnitude as a truly consolidated event within the Brazilian research community. The papers in this special issue of RITA were selectively chosen among the 24 full papers presented in SVR 2008. They are extended and revised versions of those originally presented in the symposium. The material in this special issue is representative of the wide scope of the areas covered by the symposium. The first paper, the only one not presented at the symposium, was written by the editors jointly with Luciano Soares and Veronica Teichrieb. It provides a rich panorama of current Brazilian research in Virtual Reality (VR) and related areas, based on an analysis of the 124 full papers presented over the last four SVR editions. The second paper, by Silvano Malfatti, Selan dos Santos, Luciane Fraga, Claudia Justel, Paulo Rosa, and Jauvane Oliveira, describes some interesting VR work. Its authors present an engine (EnCIMA) aimed at the quick development of VR applications. The third paper, by Fábio Miranda, Romero Tori, Cláudio Bueno, and Lucas Trias, presents research results from the Augmented Reality (AR) area. This paper, which received the best paper award in the symposium, presents a projection-based AR X-Ray tool to allow visual exploration of internal details of walls, as an illustration. The fourth paper, by Leandro Fernandes, Vitor Pamplona, João Prauchner, Luciana Nedel, and Manuel Oliveira, explores 3D user interaction. It presents the implementation of a data glove that uses a camera to track visual markers at finger tips. Finally, the last paper, by Ednaldo Pizzolato, Diego Duarte, and Marcio Fernandes, explores speech recognition as a form of interaction, introducing a software framework for application developers.

Physical disability due to any neurological disorder such as Traumatic Brain Injury (TBI), Spinal Cord Injury (SCI) or Cerebrovascular Accident (CVA) leads to motor deficit which will result in loss of control over whole body or one side of the body depending on which part of the brain is affected. In this case, physical rehabilitation is required to perform for restoration of lost functions to promote the patient's quality of life. However, traditional rehabilitation therapy requires one-to-one attention between patient and therapist. Furthermore, patients feel mundane after long term training with traditional exercises in repetitive manners. Therefore, this chapter presents the Effective Physical Rehabilitation System (EPRS) for upper limb rehabilitation by combination of augmented reality based rehabilitation exercises and biofeedback for fast recovery of motor deficit with motivational approach over traditional upper limb rehabilitation therapy which requires minimum supervision of physiotherapist. The main objective of EPRs is to restore the range of motions of upper limb and to prevent from muscle spasticity, muscle atrophy and osteoporosis in effective and motivated way. To meet this objective, augmented reality based pick and place rehabilitation exercises are developed for reaching movements. The effectiveness of the proposed system is evaluated by the experiments and questionnaires results.
