배상우, 김재일. 동적 자세측정기를 이용한 연령증가에 따른 균형기능의 변화. 운동과학, 제12권 제4호, 747-758, 2003. 본 연구의 목적은 건강한 한국인들에게서 전산화 동적 자세 측정기의 감각구성검사와 운동제어검사의 값을 이용하여 연령에 따른 균형감각을 평가하는데 있다. 전산화 동적 자세 측정기를 이용하여 균형을 평가하는데 저자들은 72명의 건강한 한국인들에게서 감각구성검사의 균형점수와 체중 균정, 잠복기, 운동제어검사의 적응점수를 연구하였다. 우리는 60대 와 20대 의 두 군으로 나누었다. 감각구성검사에 있어서 우리는 특정감각을 제거하거나 부정확한 정보를 주었을 때, 균형을 유지하는데 있어서 각각의 감각이 균형을 유지하는 바를 연구하였다. 운동제어검사에서는 갑자기 지지표면에서 앞뒤로 움직이는 연속된 검사를 통해서 자동자세 반응을 유발하였다. 운동제어검사에 있어서 말판을 갑자기 움직임으로써 잠복기틀 연구하였다. 감각구성검사에 있어서는 평균 균형점수를 20대군에서는 64-94점, 60대군에서는 55-93점으로 측정되었다. 운동제어검사에 있어서는 갑자기 앞뒤로 흔들거리는 동안 체중의 대칭성이 20대군에서는 102.9±7.9, 60대군에서는 106.3±9.0로 측정되었다. 평균잠복기는 20대군에서는 125.8-134.3msec, 60대군에서는 132.6-141.8msec로 측정되었다. 운동제어검사에서 발가락들이 위, 아래로 움직이는 검사에서는 평균 적응점수가 20대 군에서는 50-83, 34-75 점, 60대 군에서는 64-75, 48-74 점으로 각각 측정되었다. 결론적으로 균형감각의 거의 모든 수치가 청년군에 비해서 노년군에서 떨어졌다. 노년군에서의 이와 같은 감소는 감각 유입처리 과정의 능력이 떨어지는 것을 의미한다. 그리고 이것은 노령화과정에서 생체 역학 또는 중추 처리과정에서의 변화의 결과로 일어나는 것으로 사료된다. Bae, S.W., Kim, J.I. Change the balance function with aging using computerized dynamic posturography. Exercise Science. 12(4): 747-758, 2003. The purpose of this study was to evaluate the balance with aging using the values of sensory organization test(SOT) and motor control test(MCT) of computerized dynamic posturography(CDP) in the healthy Koreans. To assess the balance, we studied equilibrium score of SOT and weight symmetry, latency, and adaptation scores of MCT in 72 Korean healthy population. We divided the population into two groups, 3rd decade and 7th decade of age. In SOT, we studied the contribution of each sense to maintaining equilibrium when other senses were either absent or provided with inaccurate information. MCT provoked autonomic postural reactions through a series of sudden anterior and posterior support surface translations. In MCT, we studied latencies in sudden translation of foot plate. In SOT, the range of median equilibrium scores were from 64 to 94 in 3rd decade group, 55 to 93 in 7th decade group. In MCT, during sudden anterior and posterior perturbation, weight symmetries were 102.9±7.9 in 3rd decade group and 106.3±9.0 in 7th decade group. Median latencies were 125.8-134.3msec in 3rd decade group, 132.6-141.8msec in 7th decade group. In toes up and toes down test of MCT the mean adaptation scores were 54 to 71 and 40 to 53 in 3rd decade group, 58 to 75 and 44 to 63 in 7th decade group, respectively. In conclusion almost ail measures of balance were worse in elderly group compared with young group. The decrements in aged persons suggest decreased capacity to process sensory inputs. And this occurs most likely as a result of biomechanical or central processing changes.

Yu, Jae-Young,Park, Jea-Cheol,Jeong, Jin-Gyu 대한물리치료학회 2016 대한물리치료학회지 Vol.28 No.4

Purpose: The purpose of this study was to examine the influence of multi-directional dynamic stabilization exercise on the thickness of the external oblique abdominis, internal oblique abdominis, and transversus abdominis. Methods: For the study subjects, 40 adults were taken and divided into two groups and stabilization exercise was performed for 6 weeks. Changes in muscle thickness during the pre-experimental period, and at 2 weeks, 4 weeks, and 6 weeks were analyzed using repeated ANOVA. Results: The thickness of the external oblique abdominis, internal oblique abdominis, and transversus abdominis in the multi-directional dynamic stabilization exercise group showed significant differences per period and an interaction was observed between period and group (p<0.01), while there were no significant differences in changes per group (p>0.05). Conclusion: The effects of multi-directional stabilization exercises on abdominal muscle thickness differed. The results presented herein can be utilized as basic data for future studies and in development of rehabilitation treatments.

스포츠 생리학 : 신체활동이 평형성과 반응시간에 미치는 영향

옥정석(JungSokOak) 한국체육학회 1997 한국체육학회지 Vol.36 No.1

신체의 균형유지능력과 반응시간은 상호 밀접한 관계를 가지고 있으며 신체활동에 의해 개선될 수 있다고 알려져 있지만 그 메카니즘은 확실치 않다. 본 연구에서는 신체활동이 평형성과 반응시간에 미치는 영향을 규명하기 위하여 남녀 대학생(n=106)을 대상으로 (미)NeuroGom사의 EquiTest를 사용하여 posturography(감각구성검사와 운동제어 검사)를 실시하고 그 결과에 대한 신체활동수준간의 차이를 분석하였다. 신체활동수준의 구분은 지금까지 최소 5년 이상 스포츠 또는 무용을 수련해온 체육대학 학생들을 훈련군(남=48, 여 =21)으로 하였고 규칙적인 신체활동에 참여한 경험이 없는 일반학생들을 통제군(남=19, 여=18)으로 하였다. 연구 결과 신체활동수준이 높은 집단이 낮은 집단에 비하여 신체균형 유지를 위한 시각기능과 부적절한 체성감각시 전정 및 시각기능이 우수한 것으로 나타났다. 한편, 자동자세유지반응(automatic postural response)시 나타나는 잠복기로 측정된 반응시간을 비교한 결과 4가지 자극 조건 중 medium backward translation하에서 만이 신체활동 수준간에 유의한 차이를 보였다. 그러나 전체적으로 신체활동수준이 높은 집단이 낮은 집단보다 반응시간이 빠른 경향을 보였다. 결론적으로 신체활동수진이 높은 집단이 낮은 집단보다 시각계 및 전정기 관계에 의한 평형유지능력이 높고 근신경계의 반응이 빠르다는 사실을 발견할 수 있었다. The purpose of this study was to determine the effects of physical activity on postural balance and reaction time. Computerized dynamic posturography(EquiTest) was adopted to test sensoty organization and moter control. EquiTest facilitated the quantification of the role of somatosensory, visual and vestibular systems in the maintenance of postural balance and was also pertinent to measure the reaction time to the stimulus to change center of gravity on force platform. Posturographic data were obtained from college men(n=67) and women(n=39)》. They were each divided into two groups of untrained group(19 males & 18 females) and trained group(48 males & 21 females) who have been participating in regular physical activity for 5 years over. From the results of 2-way(sex× physical activity) ANOVA it was found that the effect of physical activity was Effects of both sex and physical activity were significant on the visual ratio in sensory analysis. Also the effect of sex on visual preference was significant. On reaction time of the latency in the automatic postural response measured in moter control test the effect of sex was significant in the condition of medium forward, large forward and large backward translation. The effect of physical activity was significant only on reaction time in the condition of medium backward translation, but the tendency of shorter reaction time was found in trained group than untrained group. It was suggested that the physical activity developed Ae function of visual system and the role of the combination of visual and vestibular systems in maintaining postural balance to surrounding stimulus, and presented shorter reaction time in automatic postural response.

정상 온도안진검사를 보이는 어지럼 환자에서 전기안진검사, 회전의자검사, 동적자세검사를 통한 전정기능 상태의 새로운 분류법 제안

염혜연,정원호,조양선,홍성화 대한평형의학회 2011 Research in Vestibular Science Vol.10 No.4

Background and Objectives: Vestibular function tests are very useful in diagnosing dizzy patients. Among them, bithermal caloric test is most commonly used test for localizing their permanent vestibular loss. However, it causes much discomfort to the patients with non-physiologic stimuli. In addition, it doesn't represent the present functional status of vestibular system. Therefore, normal caloric result does not accurately correspond to normal vestibular function in dizzy patients. Currently,rotation chair test and dynamic posturography have been introduced adjunctly to assess vestibular function accompanied by bithermal caloric test. It has not been elucidated for their specific role in diverse settings of vestibular disorders. So we planned this study to evaluate clinical usefulness of rotation chair test, videonystagmography and computerized dynamic posturogr-phy in dizzy patients with normal caloric response. Materials and Methods: We reviewed clinical records of 46 patients who met their inclusion criteria. They were categorized into five subgroups according to abnormal vestibular function test findings. Results: In each subgroup, we hypothesized its clinical relevance, possible mechanism of dizz-iness and presumed diagnosis. Five categories are as below; visual dependency, imbalance of vestibular tones, chronic peripheral vestibulopathy, abnormality in the vestibulospinal tract and abnormality of oculomotor system. Conclusion: We suggest new classification of abnormal vestibular functional status in dizzy patients with normal caloric results. These are comparable according their clinical features and thought to be helpful in managing and counseling each patient.
