Nowadays virtual reality (VR) is a common tool in neurorehabilitation. However, developing scenarios that maximize therapeutic outcome remains an ongoing challenge. In a virtual scenario with varying cognitive complexity, this study investigated the influence of cognitive abilities, arousal and motivation on movement training. Results show that cognitive demand is a crucial factor for controlling...
Rehabilitation robots, together with vision and audio systems form the multimodal environment for exercising the person in a number of ways, unavoidably influencing the physiological state of the subject. This paper examines viability of measuring psycho physiological responses to different robotic tasks. The heart rate, skin conductance, respiration and peripheral skin temperature were observed to...
This paper presents the analysis of four psychophysiological responses in post-stroke upper extremity rehabilitation. The goal was to determine which psychophysiological responses would provide the most reliable information about subjects' psychological states during rehabilitation. Heart rate, skin conductance, respiration, and skin temperature were recorded in a stroke group and a control group...
Immersive and multimodal sensory feedback was implemented to improve neurorehabilitation movement training. A major aspect of feedback is to reflect back the patient's psychophysiological state into the environment, and also to use this as a guidance mechanism as to how events within the virtual environment unfold. The virtual environment was constructed using haptic, visual and acoustic primitives...
This paper presents a case study with a HenRiE (Haptic environment for reaching and grasping exercises) device with two hemiparetic subjects. The HenRiE device is intended for use in a robot-aided neurorehabilitation for training of reaching and grasping in haptic environments. The goal of the study is to develop a single system that retrains both hand grasping and releasing movements (which are essential...
The purpose of this paper is to present the newly founded European research project MIMICS. The hypothesis of this project is that movement training for neurorehabilitation can be substantially improved through immersive and multimodal sensory feedback. The approach is real-time acquisition of behavioral and physiological data from patients and the use of this to adaptively and dynamically change...
Multimodal rehabilitation environment including haptic, visual and audio pathways is, among other, also influencing the physiological state of the subject. Heart rate, skin conductance, respiratory rate and skin temperature were measured in 30 healthy subjects during a control task, a purely mental task, a task with minor physical load and a task with major physical load. All physical activity was...
Task-oriented repetitive movements can improve motor recovery in patients with neurological or orthopaedic lesions. HEnRiE is a robot based haptic environment for simultaneous training of reaching and grasping movements. It consists of a robot with three active and two passive degrees of freedom and a grasping device with one degree of freedom. A training scenario that includes a virtual physiotherapist...
Task-oriented repetitive movement can improve movement performance in patients with neurological lesions. The application of robotics can serve to assist, enhance, evaluate and document rehabilitation of movements. ARMin is a robot for arm therapy applicable to the arm training in clinics. It has an exoskeleton structure and is equipped with position and force sensors. Our latest version ARMin II...
The paper gives insight into main fields of analysis and synthesis of human motion in the recent years or into the works that are still under development. After general introduction half to one page of description is provided for each topics. Simple explanations are omitting theoretical details and rather each use one to two pictures to provide quickly accessible information, which is similar to digest...
Task-oriented repetitive movements can improve motor recovery in patients with neurological or orthopaedic lesions. The application of robotics can serve to assist, enhance, evaluate, and document neurological and orthopaedic rehabilitation. ARMin II is the second prototype of a robot for arm therapy applicable to the training of activities of daily living. ARMin II has a semi-exoskeletal structure...
Task-oriented repetitive movements can improve motor recovery in patients with neurological or orthopaedic lesions. The application of robotics can serve to assist, enhance, evaluate, and document neurological and orthopaedic rehabilitation. ARMin is a new robot for arm therapy applicable to the training of activities of daily living in clinics. ARMin has a semiexoskeletal structure with six degrees...
Early intervention and intensive therapy improve outcome of neuromuscular disorder rehabilitation. However, a major problem is posed by considerable controversy surrounding the most appropriate method of therapy and there are still insufficient data to identify clearly the benefits of different approaches. At the same time largely still non-patient-specific methods for diagnosis and therapy are currently...
