Introduction: Several large trials of task based rehabilitation examining interventions designed to meet the main tenets of experience-dependent neuroplasticity have failed to identify an approach to rehabilitation that produces improvements in hand function that consistently returns persons with stroke to their pre-stroke levels of activity and participation. Several scholars have identified the...
This paper proposed a VR-based self-rehabilitation system which utilizes the virtual training model rendered by OpenGL and collects electromyography (EMG) signals from the subjects to perform hand motion recognition. EMG signals are biomedical signals generated in muscles and can be applied in many fields such as clinical diagnosis and biomedical applications. The subjects were asked to manipulate...
Haptic technology has many real world applications such as rehabilitation robotics, telepresence surgery, gaming, virtual reality and human-robot interaction. Force plays an important role in the above mentioned haptic applications. In this paper, we propose a method to estimate force from surface Electromyography (SEMG) signals using Artificial Neural Network (ANN). The haptic device is modeled to...
A recent trend in virtual environments aims at making the user free of devices or limitations in its motion, at the benefit of immersiveness and interactivity. This work introduces an interaction paradigm that goes beyond motion based interaction, by making use of measured real forces exerted by the user in free space. The sensation of touch with virtual object is obtained by vibrotactile stimulation...
Current changes in aging demographics poses new challenges: people require to keep their quality of life even after circumstances that threatened their movement and function. This increases the demand for new physical rehabilitation facilities that go beyond the traditional patient-therapist, one-to-one rehabilitation sessions. Two promising solutions rely on virtual reality and on the development...
The ability to use haptic input through light contact to improve stability while walking post-stroke is investigated in a virtual environment (VE). Persons with stroke and healthy participants walk in a VE where they encounter changes in the slope of the support surface. Kinematic, kinetic, and electromyographic data analyses will be used to show the anticipatory postural adjustments made leading...
