The purpose of this study was to investigate the effects of virtual reality bowling on emotional changes using EEG (Electroencephalogram). Sixteen bowling players who have at least three years of experiences in bowling participated in this study. Their aged ranged from 26 to 35 years old with a mean age of 29.6 years. The frontal lobes (Fp2-Fp1, F4-F3, F8-F7) of each player were measured while subjects were performing five games of bowling. And after performing every frame, their emotion was measured immediately with Visual Analogue Scale. The data were analyzed by one-way analysis of variance to test differences in the alpha value of each region of the frontal lobes. The dependent variable is the alpha power of the cerebral asymmetry. The results showed that players who scored a strike showed higher VAS values than those who missed the spares or cleared the spares; those who cleared spares showed higher VAS values than those who missed spares In addition, with respect to frontal R-L asymmetry score, the alpha-wave of the left frontal lobe was activated when scoring a strike and clearing spares and the alpha-wave of the right frontal lobe was activated when missing spares. In conclusion, the results of this study demonstrated that success or achievement in competition gives rise to positive emotions and vice versa. This study neurophysiologically proved that performance outcomes during a competition directly influence players' emotion and brain waves.

This study aims to examine whether the use of a spinal column thermal massage device for patients with muscle pain is effective in improving muscle pain, and to verify whether it is also effective in improving affective depression and stress. To this end, 16 study participants (male 31.25%) were treated with a thermal massage device during 5 sessions a week for 4 weeks and 40 minutes per session. According to the study results, the subjective pain level changed by a rate of VAS -46.32% and PDI -44.86%; a significant decrease was observed in, both, VAS and PDI. The depression and stress levels changed by a rate of BDI -21.84% and SRI -11.48%; a significant decrease was observed in, both, BDI and SRI. Therefore, the use of a thermal massage device to treat patients with muscle pain is expected to have a positive effect in improving not only subjective muscle pain, but also depression and stress.

This paper investigates several methods of visualizing high-dimensional data in a low-dimensional space. At first, principal component analysis and multidimensional scaling are briefly introduced as linear approaches, and then kernel principal component analysis, self-organizing map, locally linear embedding, Isomap, Laplacian Eigenmaps, and local multidimensional scaling are introduced as nonlinear approaches. In particular, t-SNE, which is widely used but relatively unfamiliar in the field of statistics, is described in more detail. We also present a simple example for several methods, including t-SNE. Finally, we provide a review of several recent studies pointing out the limitations of t-SNE and discuss the future research problems presented.

To investigate the relationship between breathing pattern disorder and pain in patients with chronic low back pain(CLBP). One hundred four patients were measured the End-tidal CO₂(EtCO₂) and respiration rate(RR) using capnography. Also, The Breathing-hold time(BHT), Nijmegen Questionnaire(NQ), and Thoracic excursion examinated. There was a significant correlation between EtCO₂ and BHT, thoracic excursion(r=.302, r=.281)(p<.01), and a low negative correlation with RR, VAS(r=-.253, -200)(p<.05). There was a significant correlation between NQ and RR(r=.237)(p<.05). There was a low correlation between thoracic excursion and VAS(r=-.370)(p<.01). There was a significant difference in the EtCO₂, RR, BHT, thoracic excursion, and VAS between the thoracic and diaphragm breathing pattern(p<.05). There were no significant differences in the NQ(p>.05). There was a correlation between EtCO₂ and BHT, thoracic excursion, RR, VAS in patients with CLBP. In addition, There was a correlation between RR and NQ, thoracic excursion, and VAS. As a result, it was found that there is a close relationship between breathing pattern disorder and pain. There was a significant difference in the EtCO₂ level, RR, BHT, thoracic excursion and VAS value in the comparison of thoracic breathing pattern and diaphragm breathing pattern. This is a meaningful result of suggesting a breathing pattern treatment approach in the rehabilitation and pain management of chronic low back pain patients in clinical practice.

The purpose of this study was to provide basic data on the thera-tainment intervention method and to relieve dysmenorrhea by identifying the effects of silver spike point therapy on menstrual pain, muscle tone, and muscle stiffness among 30 women in their 20s. The subjects had a regular menstrual cycle, had a visual analog scale score of more than 4 for dysmenorrhea pain, and did not have any gynecological disease. SSP therapy was applied for 20 minutes on San-Yin-Jiao on the first day of their menstrual cycles. Muscle tone and stiffness were measured with Myoton before treatment, immediately after treatment, and 3 hours after treatment. SPSS version 19 was used to analyze the collected data. Using Friedman test, muscle tone and stiffness were measured before treatment, immediately after treatment, and 3 hours after treatment. The results indicate that after treatment dysmenorrhea pain steadily decreased and muscle tension and stiffness decreased significantly. This shows that using SSP therapy is effective on reducing primary dysmenorrhea and improving women's health care. This shows that using SSP therapy is effective at reducing primary dysmenorrhea and improving women's health care.

The purpose of this study was to investigate effect of type of physical therapy (spinal stabilization exercise and manual therapy) on pain index and disability index in acute and subacute patients with low back pain (LBP). 23 patients with LBP participated and were randomly assigned. Manual therapy and spinal stabilization exercise was applied for 15-minute sessions occurred 3 sessions a week, for 4 weeks. All subjects received conservative therapy for 30-minute. Visual analogue scale (VAS) and Korean version of Oswestry disability index (ODI-K) were measured before and after treatment. There was significant difference in VAS and ODI-K between before and after both treatment (p<.05). There was significant difference in change rate of VAS between manual therapy and spinal sabilization exercise (p<.05), but not in change rate of ODI-K (p>.05). Thus, it is suggested that spinal stabilization exercise is helpful to reduce pain safely in acute and subacute patients with LBP.

The effect of kinesio taping in patients with common peroneal nerve paralysis (PNP) have not been investigated. This purpose of this study was to evaluate the effects of kinesio taping on patients with common PNP. Ten subjects who had common PNP were included in this study. Kinesio taping was applied to the ankle joint (direction of dorsiflexion and eversion). The measurements were by manual muscle test (MMT; tibialis anterior, peroneus longus), active ROM (ankle dorsiflexion, eversion), pain (visual analogue scale (VAS), pressure pain threshold (PPT)), and balance (one leg standing). Subjects were assessed at baseline and 8 weeks of intervention. In the results, all subjects showed improvements in MMT, active ROM, Pain and balance at the 8-week. These findings are considered to be effective in applying kinesio taping on ankle joint in common PNP patients.

Recently, incorrect and unhealthy postures have become increasingly prevalent due to reasons such as smartphone use. Consequently, imbalanced muscle contraction occurs. In particular, if the oblique muscle is contracted, the accessory nerve will be compressed, causing ischemic pain in the upper trapezius muscle. To investigate the effect on pain in the upper trapezius muscle, this study applied the ischemic compression method to the accessory nerve capture point at the 1/3-point of the oblique cervical muscle. In this study, the ischemic compression method was applied to eight women twice a week for four weeks, and pain was evaluated before, immediately after, and three weeks after application. The visual analogue scale, McGill Pain Questionnaire, and pressure dynamometer were used to evaluate subjects' pain. As a result of this study, it was confirmed that the pain was significantly reduced after treatment, and that the pain reduction was still effective three weeks after completion of the intervention, indicating that the intervention on the accessory nerve compression point on the oblique cervical muscle was both effective and long-lasting for pain reduction in the upper trapezius muscle. Future studies should increase the number of subjects to check not only pain reduction in the upper trapezius muscle, but also improvement of neck function.
