Tripolar concentric ring electrode (TCRE) sensors have unique properties. These sensors have been used to acquire various bio-signals such as: electroencephalography (EEG), electrocardiography (ECG), and electromyography (EMG). Compared to conventional disc electrode signals TCRE EEG (tEEG) has four times better signal-to-noise ratio, eleven times better mutual information and spatial resolution....
Motor imagery (MI) based Brain-Computer Interfaces (BCIs) controlled Functional Electrical Stimulation (FES) can help people with severe neuromuscular impairments to control their limbs by bypassing peripheral nerves and muscle pathways. However, there are still four major limitations with current MI-based BCIs for FES control: 1) They require relatively longer training and the training procedures...
Electroencephalography (EEG) has long been used for Brain computer interface (BCI). Recent researches have proved that EEG can be also used to classify data generated in speech imagery. This classification can further be utilized to develop speech prosthesis and synthetic telepathy systems. In this paper we wanted to check whether features extracted from beta, delta and theta rhythms of EEG can be...
To obtain a high-quality surface electromyography (EMG) recording, the signal must be acquired as far as possible from the muscle innervation and tendon zone. This study presents a technique to indicate better electrode positions for surface EMG of the upper limb muscles during wrist extension and flexion. Ten volunteers participated in this research. Surface EMG signals were collected from flexor...
The severely disabled people have difficulties in communication with other people because they can hardly move their body. To understand the intention of disabled people, communication devices using eye movement have been developed. In these systems, the user can click by keeping the stationary gaze during the predetermined time. However, the gaze stationarily induced by discursive looking may cause...
Background: Reports indicate that percutaneous posterior tibial nerve stimulation improve pain symptoms of the patients with chronic pelvic pain. Objective: The aim of this study is to assess the efficacy of bilateral transcutaneous posterior tibial nerve stimulation (PTNS) for functional anorectal pain. Design: Prospective study. Single-group pilot study. Patients: 10 patients with functional anorectal...
The ability to walk is a very important characteristic of the human being that unfortunately not everyone can enjoy. Subjects with spinal cord damage or who have had a stroke may have difficulties in walking, or even be unable to walk, depending on their degree of disability. Although, in some cases, it is possible to recover mobility, the rehabilitation process can continue for long periods of time...
A Brain-Computer Interface (BCI) provides a completely new output pathway and so an additional possible way a person can express himself if he/she suffers disorders like amyotrophic lateral sclerosis (ALS), brainstem stroke, brain or spinal cord injury or other diseases which impair the function of the common output pathways which are responsible for the control of muscles or impair the muscles. Although...
Electroencephalography (EEG) signal between normal and special children is slightly different. Different types of special children will generate different shape of EEG patterns depend on their neurological function. This paper demonstrates the classification of EEG signal for special children: to determine and to classify level and pattern of EEG signal for autism and Down syndrome children. EEG signal...
We assessed the effects of the addition of dynamic visual elements and sounds to a levee patroller training game on the appraisal of the environment and weather conditions, the engagement of the users and their performance. Results show that the combination of visual dynamics and sounds best conveys the impression of severe weather conditions and most strongly influences the appraisal of the environment...
