The aim of this article was to determine clinical significance of neurofeedback training of children with attention-deficit/hyperactivity disorder (ADHD). Many previous studies showed that the characteristic pattern of electroencephalogram (EEG) can be found in ADHD children. Neurofeedback training is developed based on this characteristic EEG pattern. Theta power and theta/beta power ratio have been known as useful indicators of neurofeedback training. However, in Korea, direct analysis of EEG change patterns before and after neurofeedback training is very rare. We reviewed the current findings of neurofeedback training of children with ADHD, and its clinical implications were discussed.

This paper proposed a rehabilitation training system with electromyography (sEMG) feedback for stroke patients based on ARM embedded system and LabVIEW. The system can achieve real-time acquisition, processing and dualview of multi-channel sEMGs and compute related sEMG parameters including iEMG, RMS, MPF and co-contraction ratio. The system was detected by clinical experiments and related inspection department. The result showed that the system is functional, interactive and in accordance with the relevant standards for medical devices so that it can fully satisfy the clinical demands. In addition, the system can help doctors to master the training state of the patient more effectively in a real-time and quantitative way that is direct to improve the training programs of stroke patients.

Neurofeedback, as an alternative treatment method of behavioral medicine, is a technique which translates the electroencephalogram (EEG) signals to styles as sounds or animation to help people understand their own physical status and learn to enhance or suppress certain EEG signals to regulate their own brain functions after several repeated trainings. This paper develops a neurofeedback system on the foundation of brain-computer interface technique. The EEG features are extracted through real-time signal process and then translated to feedback information. Two feedback screens are designed for relaxation training and attention training individually. The veracity and feasibility of the neurofeedback system are validated through system simulation and preliminary experiment.

Neurofeedback (NFB) allows subjects to learn how to volitionally influence the neuronal activation in the brain by employing real-time neural activity as feedback. NFB has already been performed with electroencephalography (EEG) since the 1970s. Functional MRI (fMRI), offering a higher spatial resolution, has further increased the spatial specificity. In this paper, we briefly outline the general principles behind NFB, the implementation of fMRI-NFB studies, the feasibility of fMRI-NFB, and the application of NFB as a supplementary therapy tool.

In order to solve the problems of insufficient stimulation channels and lack of stimulation effect feedback in the current electrical stimulation system, a functional array electrode electrical stimulation system with surface electromyography (sEMG) feedback was designed in this paper. Firstly, the effectiveness of the system was verified through

Attention-deficit hyperactivity disorder (ADHD) is a neuropsychiatric disorder that begins in early childhood and can persist throughout adulthood. ADHD causes difficulties in various area of life, such as academic achievement, peer relationships, family functioning, employment and marriage. Although ADHD is known to respond well to medication, such treatment is more effective when combined with psychosocial (non-pharmacologic) therapy in terms of alleviating the core symptoms and improving appropriate functions. Psychosocial treatment interventions are divided into psychoeducation, behavioral parent training, school intervention, cognitive behavior therapy, social skill training, parent-child interaction therapy, play therapy, other treatments (coaching, complementary and alternative medicine), neurofeedback and Cogmed. Adult ADHD cognitive behavioral therapy is described separately. These practice parameters summarize the evidence for psychosocial treatment. Based on this evidence, specific recommendations are provided for psychosocial interventions.

Since the pharmacological treatment of insomnia has the potential risk for dependence and various side effects, nonpharmacological intervention for insomnia is very important in clinical practice. The neurophysiological characteristics and recent researches using quantitative EEG of insomnia suggest the insomnia as a state of CNS(central nervous system) hyperarousal. Insomnia should not be restricted to subjective sleep complaints alone because it appears to be a 24-hour disorder including daytime fatigue and decreased quality of life. The neurofeedback treatment is a self-regulation method based on the paradigm of operant conditioning. The goal of this treatment modality is to normalize the functioning of the brain by inhibiting and/or reinforcing specific frequency bands of brain waves. Therefore, the neurofeedback treatment on the basis of thalamocortical mechanisms which play an important role in sleep and arousal might be a useful treatment modality for the insomnia in the future. In this paper the authors suggest the clinical applications of neurofeedback for the treatment of insomnia and further clinical researches about its therapeutic effects in insomnia.

OBJECTIVES: The slow cortical potential (SCP) training is one of the methods of neurofeedback which is considered as an adjunctive treatment for attention deficit hyperactivity disorder (ADHD). The purpose of this study was to investigate the effect of the SCP training in children with ADHD. METHODS: Subjects were consisted of 12 children aged between 7 and 13 years and all of the subjects have completed neuropsychological tests to assess their cognitive and executive functioning, before and after their neurofeedback training. Their parents have completed the Korean-ADHD Rating Scale (ARS). Each subject was given 30 sessions of SCP training. RESULTS: The inattention scores and total ARS scores of the subjects have decreased (Z=-2.54, p<0.05, Z=-2.26, p<0.05, respectively) after training, but the hyperactivity/impulsivity scores did not show significant improvement. The commission error scores for both the visual and auditory ADHD diagnostic system (ADS) showed a trend toward improvement after training (p=0.053, p=0.092, respectively). The larger improvement of positive task of feedback trial, which is one of the methods of SCP training, was associated with the larger reduction of ARS total scores (p<0.05) and the larger improvement of negative task of transfer trial was associated with a larger reduction of omission error scores of auditory ADS (p<0.05). CONCLUSION: This study suggests that the SCP neurofeedback program may improve ADHD symptoms and assumes that SCP training is a viable treatment option for ADHD treatment.
