[Purpose] While electromyography (EMG) biofeedback has been recently used in diverse therapeutic interventions for stroke patients, research on its effects has been lacking. Most existing studies are confined to functions of the lower extremities, and research on upper extremity functional recovery using EMG biofeedback training is limited. Therefore, this study examined the effects of training using EMG biofeedback on stroke patients’ upper extremity functions. [Subjects and Methods] The subjects of this study included 30 hemiplegia patients whose disease duration was longer than six months. They were randomly divided into a control group (n=15) receiving traditional rehabilitation therapy and an experimental group (n=15) receiving both traditional rehabilitation therapy and training using EMG biofeedback. The program lasted for a total of four weeks. In order to examine the subjects’ functional recovery, the author measured their upper limb function using the Fugl-Meyer Assessment and Manual Function Test, and activities of daily living using the Functional Independence Measure before and after training. [Results] A comparison of the study groups revealed that those in the experimental group experienced greater improvement in upper extremity function after training in all tests compared to the control group; however, there was no significant difference in terms of the activities of daily living between the two groups. The results of this study were as follows. [Conclusion] Thus, stroke patients receiving intensive EMG biofeedback showed more significant upper extremity functional recovery than those who only received traditional rehabilitation therapy.

Spiraea prunifolia var. simpliciflora (SP) is traditionally used as an herbal remedy to treat fever, malaria, and emesis. This study aimed to evaluate the anti-oxidative and anti-inflammatory properties of the methanol extract of SP leaves in tumor necrosis factor (TNF)-α-stimulated NCI-H292 cells and in a lipopolysaccharide (LPS)-induced acute lung injury (ALI) mouse model. SP decreased the number of inflammatory cells and the levels of TNF-α, interleukin (IL)-1β, and IL-6 in the bronchoalveolar lavage fluid, and inflammatory cell infiltration in the lung tissues of SP-treated mice. In addition, SP significantly suppressed the mRNA and protein levels of TNF-α, IL-1β, and IL-6 in TNF-α-stimulated NCI-H292 cells. SP significantly suppressed the phosphorylation of the mitogen-activated protein kinases (MAPKs) and p65-nuclear factor-kappa B (NF-κB) in LPS-induced ALI mice and TNF-α-stimulated NCI-H292 cells. SP treatment enhanced the nuclear translocation of nuclear factor erythroid 2-related factor (Nrf2) with upregulated antioxidant enzymes and suppressed reactive oxygen species (ROS)-mediated oxidative stress in the lung tissues of LPS-induced ALI model and TNF-α-stimulated NCI-H292 cells. Collectively, SP effectively inhibited airway inflammation and ROS-mediated oxidative stress, which was closely related to its ability to induce activation of Nrf2 and inhibit the phosphorylation of MAPKs and NF-κB. These findings suggest that SP has therapeutic potential for the treatment of ALI.

[Purpose] This study examined the effects of training using virtual reality games on stroke patients’ functional recovery. [Paticipants and Methods] Twenty-four hemiplegia patients whose disease duration was longer than six months participated in this study. The participants were divided at random into a control group (n=12), which received traditional rehabilitation therapy, and an experimental group (n=12), which received both traditional rehabilitation therapy and training using virtual reality games. The program lasted for a total of 12 weeks. To examine the participants’ functional recovery, their upper limb function was measured using the Fugl-Meyer Assessment and Manual Function Test before and after they completed the training and their daily living activities were measured using the Stroke Impact Scale before and after they completed the training. [Results] The experimental group participants’ daily living activities improved after training. In addition, the experimental group scored significantly higher on all the tests than the control group, but upper extremity function between the groups was not significantly different. [Conclusion] Stroke patients who completed the additional training using virtual reality games showed significantly greater improvement in their daily living activities than those who only received traditional rehabilitation therapy.

These results suggest that needle insertion velocity might be a factor for controlling inadvertent pain during the acupuncture needling process and that biomechanical properties of needling may be related to acupuncture perception or sensation.

The purpose of this study is to investigate the clinical trial research trends in regards to the Neurofeedback(NF) intervention in Korean journals. literature review was conducted on the domestic journals published from 2007 to 2016 and they searched six electronic databases to find relevant articles, using the term 'Electroencephalography', 'Neurofeedback'. Attention deficit hyperactivity disorder(ADHD) were most frequently studied with NF training. other studies Stroke, Intellectual disability, Hearing impairment, Depressive disorder, Traumatic brain injury, Dementia, Temporomandibular disorder and Tic disorder. NF interventios were attempted in diverse training protocols and assessed with many defferent outcome measurements. The result of this showed that the intervention of NF in client is effective for the recovery of the physical functions related to Neuromusculoskeletal system, mental function of client.. For a better result of study related to this field, more systematic researches should be followed, overcoming the existing limitations and particularly the applicability and effect of NF training need tapping more.
