This paper discusses and evaluates the role of shared control approach in a BCI-based telepresence framework. Driving a mobile device by using human brain signals might improve the quality of life of people suffering from severely physical disabilities. By means of a bidirectional audio/video connection to a robot, the BCI user is able to interact actively with relatives and friends located in different rooms. However, the control of robots through an uncertain channel as a BCI may be complicated and exhaustive. Shared control can facilitate the operation of brain-controlled telepresence robots, as demonstrated by the experimental results reported here. In fact, it allows all subjects to complete a rather complex task, driving the robot in a natural environment along a path with several targets and obstacles, in shorter times and with less number of mental commands. ©2010 IEEE.

This study intended to describe general personality functioning in patients with a progressive course of multiple sclerosis. 55 consecutive rehabilitation inpatients with progressive course of multiple sclerosis were assessed with a multimethod test battery: the Expanded Disability Status Scale, the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Rosenberg Self-esteem Scale, and the Rorschach Test administered and scored with Comprehensive System. The control group comprised 55 healthy participants with similar sociodemographic characteristics. Specific differences were found for both cognitive and affective aspects, as the patients with progressive course of multiple sclerosis had less positive self-image, less effective mediation processing, and an affective approach to reality. Present data illustrated the usefulness of examining patients with a progressive course of multiple sclerosis to identify abilities and difficulties in cognitive and affective patterns, and support better adaptation to relationships and the environment. © Psychological Reports 2010.

Background. Six months after a stroke, the hemiplegic arm often remains compromised. More innovative approaches to motor rehabilitation are needed. Objective. The authors compared a motor learning-based approach in a virtual environment with more conventional upper extremity therapy in a pilot trial. Methods. This prospective, single-blinded, randomized controlled trial compared reinforced feedback in a virtual environment (RFVE; n = 27) with a control intervention (n = 20) of progressive therapy for the affected upper extremity. Both treatments were provided for 4 weeks, 5 days per week, with 1-hour treatment sessions daily. The primary outcomes were the Fugl-Meyer Upper Extremity (F-M UE) and Functional Independence Measure (FIM) scores. Kinematic outcomes included mean duration (MD), mean linear velocity (MLV), and number of submovements to measure the motor performance. Analyses of the primary outcomes were performed per protocol and by intention to treat. Results. F-M UE scores improved significantly in the RFVE group compared with the conventional therapy group (“intention to treat” = 5.10 points, P =.004; ANCOVA = 4.26 points, P <.01). Several of the kinematic parameters improved in the RFVE group (MD, P <.01; MLV, P <.01). FIM improvements did not differ. Conclusions. Both rehabilitation therapies improved arm motor performance and functional activity, but the RFVE therapy induced more robust results in patients exposed to late rehabilitation treatment. © 2010 The Author(s).

Coenzyme Q10 (CoQ10) deficiency has been associated with an increasing number of clinical phenotypes. Whereas primary CoQ10 defects are related to mutations in ubiquinone biosynthetic genes, which are now being unraveled, and respond well to CoQ10 supplementation, the etiologies, and clinical phenotypes related to secondary deficiencies are largely unknown. The purpose of this multicenter study was to evaluate the frequency of muscle CoQ10 deficiency in a cohort of 76 patients presenting with clinically heterogeneous mitochondrial phenotypes which included myopathy among their clinical features. A reliable diagnostic tool based on HPLC quantification was employed to measure muscle CoQ10 levels. A significant proportion of these patients (28 over 76) displayed CoQ10 deficiency that was clearly secondary in nine patients, who harbored a pathogenic mutation of mitochondrial DNA. This study provides a rationale for future therapeutic trials on the effect of CoQ10 supplementation in patients with mitochondrial diseases presenting with myopathy among clinical features. © 2009 Elsevier B.V.

In this paper we present the first results of users with disabilities in mentally controlling a telepresence robot, a rather complex task as the robot is continuously moving and the user must control it for a long period of time (over 6 minutes) to go along the whole path. These two users drove the telepresence robot from their clinic more than 100 km away. Remarkably, although the patients had never visited the location where the telepresence robot was operating, they achieve similar performances to a group of four healthy users who were familiar with the environment. In particular, the experimental results reported in this paper demonstrate the benefits of shared control for brain-controlled telepresence robots. It allows all subjects (including novel BMI subjects as our users with disabilities) to complete a complex task in similar time and with similar number of commands to those required by manual control. © 2011 IEEE.

Offline analysis pipelines have been developed and evaluated for the detection of covert attention from electroen-cephalography recordings, and the detection of overt attention in terms of eye movement based on electrooculographic measurements. Some additional analysis were done in order to prepare the pipelines for use in a real-time system. This real-time system and a game application in which these pipelines are to be used were implemented. The game is set in a virtual environment where player is a wildlife photographer on an uninhabited island. Overt attention is used to adjust the angle of the first person camera, when the player is tracking animals. When making a photograph, the animal will flee when it notices it is looked at directly, so covert attention is required to get a good shot. Future work will entail user tests with this system to evaluate usability, user experience, and characteristics of the signals related to overt and covert attention when used in such an immersive environment. © 2011 IEEE.

Background. In 2007, Schiff et al reported a patient in a minimally conscious state (MCS) who responded to deep brain stimulation (DBS), but clinicians cannot predict which patients might respond prior to the implantation of electrodes. Methods. A patient in a MCS for 5 years participated in an ABA design alternating between repetitive transcranial magnetic stimulation (rTMS) and peripheral nerve stimulation. rTMS (condition A) involved the delivery of 10 trains of 100 stimuli at 20 Hz using a stimulator with a 70-mm figure-of-eight coil to elicit a contraction of the abductor pollicis brevis. Condition B used median nerve electrical stimulation. Results. After peripheral stimulation, the patient did not exhibit clinical, behavioral, or electroencephalographic (EEG) changes. The frequency of specific and meaningful behaviors increased after rTMS, along with the absolute and relative power of the EEG δ, β, and α bands. Conclusion. These results suggest that rTMS may improve awareness and arousal in MCS. If these results are reproducible, rTMS may identify subgroups of MCS patients who might benefit from DBS. © The Author(s) 2011.

The aim of this work is to present the development of a hybrid Brain-Computer Interface (hBCI) which combines existing input devices with a BCI. Thereby, the BCI should be available if the user wishes to extend the types of inputs available to an assistive technology system, but the user can also choose not to use the BCI at all; the BCI is active in the background. The hBCI might decide on the one hand which input channel(s) offer the most reliable signal(s) and switch between input channels to improve information transfer rate, usability, or other factors, or on the other hand fuse various input channels. One major goal therefore is to bring the BCI technology to a level where it can be used in a maximum number of scenarios in a simple way. To achieve this, it is of great importance that the hBCI is able to operate reliably for long periods, recognizing and adapting to changes as it does so. This goal is only possible if many different subsystems in the hBCI can work together. Since one research institute alone cannot provide such different functionality, collaboration between institutes is necessary. To allow for such a collaboration, a new concept and common software framework is introduced. It consists of four interfaces connecting the classical BCI modules: signal acquisition, preprocessing, feature extraction, classification, and the application. But it provides also the concept of fusion and shared control. In a proof of concept, the functionality of the proposed system was demonstrated.
