Purpose: This study aims to investigate the immediate effects of electromyography (EMG) biofeedback training of the gluteus medius on dynamic balance during single leg squats in healthy individuals. Methods: The sample size in this study was estimated using the G-power program at an effect size of 0.4, a significance level (α) of 0.05, and a testing power of 0.90. In addition, as a result of considering the 10% dropout rate, this study recruited 21 healthy individuals (8 males and 13 females). All subjects measured the Y-balance test-lower quarter (YBT-LQ) and limits of stability (LOS) before and after a single leg squat (SLS) and SLS with EMG biofeedback training of the gluteus medius (SLSEB). They were trained for 10 minutes for each exercise, and two dynamic balance tests were performed three times. Results: There was a significant difference in the YBT-LQ score between the two exercises (p < 0.05). In the YBT-LQ score, there was a significant difference before and after SLS and SLSEB (p < 0.05). SLSEB showed a significantly higher YBT-LQ score than SLS (p < 0.05). There was a significant difference in LOM between the two exercises (p < 0.05). However, there was no significant difference between the two exercises. Conclusion: A single-leg squat with EMG biofeedback exercises is an effective method to improve dynamic balance, such as the YBT-LQ.

본 연구는 아동을 대상으로 기녈 정서(기쁨·슬픔·분노·스트레스·무료함)를 유발시키는 정서프로토콜을 개발하고 이를 표준화하고자 실시되었다. 음악·색깔·정서전달도구를 이용하여 각각의 정서를 유발시키는 상황을 구성하였다. 정서평가를 위해서 아동용 정서평가척도를 개발하였다. 아동은 5가지의 정서상황을 경험한 후, 자신의 정서상태를 평가하였다. 정서프로토콜에 대한 평가는 아동의 자기보고와 전문가의 행동관찰분석으로 이루어졌다. 그 결과, 개발된 정서프로토콜은 각각의 기본정서를 효과적으로 유발시킨 것으로 나타났다. 연령별·성별 비교에서는, 남아보다는 여아가 무료함을 더 강하게 느꼈으며, 학령이후의 아동은 학령이전의 아동보다 슬픔에 더 민감한 것으로 나타났다.

Purpose : The purpose of this study is to ascertain whether age, body mass index(BMI) and exercise frequency(EF) are correlated with knee joint position sense in healthy women. Methods : Healthy women of 150 who participated in this study were tested knee joint position sense; each reposition error was analyzed according to the age, BMI and EF. Reposition error was measured with a Myrin goniometer. Results : The age groups, BMI groups and EF groups demonstrated significant differences of the knee joint position sense. The older the healthy women are, the higher BMI is, and the lower EF is, the more decreased knee joint position sense has become. Conclusion : The older the women are, the higher BMI is, and the lower EF is, the more decreased the knee joint position sense in healthy women is. Therefore it needs to be considered to require management of obesity and regular exercise for prevention of knee injuries due to decreased joint position sense.

Purpose: The purpose of this study was to compare the effects of force of ipsilateral versus contralateral cane usage on knee moments in healthy young adults. Methods: A convenience sample of 10 subjects volunteered for this study. Subjects walked over a force plate under three different conditions; unaided and ipsilateral cane and contralateral cane. Analysis of data on moment of the knee joint and ground reaction force was performed using the OrthoTrak program. Results: Flexion moment of the knee was decreased with the contralateral cane, but increased with the ipsilateral cane compared with normal gait. Extension moment of the knee was decreased with the contralateral cane compared with normal gait(p<0.05) and it was showed a greater decrease with the contralateral cane than with the ipsilateral cane gait(p=0.00). Valgus moment of the knee joint was increased with the ipsilateral cane but decreased with the contralateral cane. Vertical ground peak force was decreased with the ipsilateral cane compared with normal gait (p<0.05). Conclusion: The following conclusions were drawn from our data. Contralateral cane gait is more efficacious for persons with weakness of knee extensors, however, for a patient with varus deformity, the cane should be used in the ipsilateral hand.

본 연구는 fMRI를 사용하여 정서유발단어에 의한 주의이동과 관련한 뇌신경망을 규명하기 위하여 12명의 오른손잡이 여대생을 대상으로 수행하였다. fMRI 실험을 위한 뇌활성화 과제는 예비실험을 통하여 선정된 행복, 슬픔, 위협에 해당하는 각각 36개씩의 단어와 각 단어의 짝을 이루기 위한 중성단어를 이용하여 변형된 Posner 패러다임을 블록디자인으로 고안하였다. fMRI 영상은 1.5T Simens Vision scanner를 사용하여 실시하였으며, single-shot EPI 기법으로(TR/TE:3840/40ms, flip angle: 90, FOV: 220, 64x64 matrix, Slice thickness: 6mm) 이미지를 얻었고 피험자의 반응시간을 기록하였다. 자료분석은 SPM-99 소프트웨어를 사용하였다. 정서유발단어는 중성단어에 비하여 반응시간이 의미있게 빨라 효과적인 주의이동이 일어났음을 알 수 있었다. 정서유발단어와 중성단어에 의한 뇌활성화 상태를 감산분석한 결과, 좌측 상두정엽, 양측 후두엽 및 소뇌에서 뇌활성화를 보였고, 이들 영역은 정서유발단어에 의한 주의이동시 특징적으로 활성이 일어나는 뇌영역임을 보여주었다. 또한 여러 가지 정서가를 가진 단어에 의해 유발되는 주의의 정도가 특징적인 신경망의 활성과 관련되어 있음을 알 수 있었다. The purpose of this study is to delineate the neural network related to the shift of attention and its modulation by emotion-provoking words using functional MRI (fMRI). Twelve right-handed normal female volunteers participated in fMRI study. Their mean age was 24 years and the mean modified Edinburgh score was +90. Emotion-provoking words representing happy, sad, threatened, and neutral emotional valences respectively were chosen by the assessment of 60 normal volunteers using semantic differentiation and Mannequin scales. The activation tasks were designed using modified Posner's paradigm to have 4 blocks of each emotional and control periods, Imaging was conducted on a 1.5T Siemens Vision scanner. Single-shot echoplanar images (TR/TE = 3840/40 ms, flip angle = 90, FOV = 220, matrix = 62 ? 64, slice thickness = 6㎜) were acquired in 20 contiguous slices parallel to the AC_PC line as well as conventional T1-weighted images. Response times were obtained during the scanning, Imaging data were realigned, coregistered, normalized, smoothed, and statistically analyzed in group using SPM-99 software. The results showed that emotional valence of word stimuli produced the effect of attentional engagement. The left superior parietal, inferior frontal, bilateral occipital lobes and cerebellum were main area of modulation of attentional network by emotional words stimuli. The different extent of brain activation induced by different emotion-provoking words were determined.

본 연구는 아동을 대상으로 기쁨, 슬픔, 분노, 스트레스와 무료함의 다섯 가지 정서를 유발시키는 정서프로토콜을 개발하고 이를 표준화하고자 실시되었다. 심상을 유발하는 이야기·음악·색깔·인형을 이용하여 각각의 정서를 유발시키는 상황을 구성하였다. 또한 정서 평가를 위하여 아동용 정서평가척도를 개발하였다. 아동은 다섯 가지의 정서 상황을 경험한 후, 자신의 정서 상태를 평가하였다. 정서 프로토콜에 대한 평가는 아동의 자기보고와 전문가의 행동 관찰 분석으로 이루어졌다. 연구 결과, 개발된 정서 프로토콜은 각각의 정서를 효과적으로 유발시킨 것으로 나타났다. 연령별·별 비교에서는, 남아보다는 여아가 무료함을 더 강하게 느꼈으며, 학령 이후의 아동은 학령이전의 아동보다 슬픔에 더 민감한 것으로 나타났다. The aim of this study was to develop a research protocol that provides standardized conditioning stimuli in effectively evoking emotion-specific responses in children. The protocol targets five specific emotions(i.e., happiness, sadness, anger, distress, and boredom) by introducing study participants to a combination of music, color, stories, and dolls. This research protocol also includes a self-report emotion assessment scale specially developed for this study to verify the types of emotion induced. Evaluation of the method entailed triangulation of the results from the subjects` self-reported emotional state corresponding to each conditioned stimulus as well as behavioral observations conducted by researchers. Findings suggest that this new protocol effectively evokes five emotions in correspondence to the way it was intended for appropriate emotion induction. Additionally, results showed that female children than male children are more likely to feel boredom; and school-aged children were more likely to react to sadness than pre-school children.
