Purpose: The purpose of this study is to find out how gait training with shoulder-back assistive device affects dynamic and static balance, gait of patients with stroke and to help improve body alignment, balance, and gait ability in stroke patients. Methods: Measurements were taken of the 20 subjects before intervention without shoulder-back assistive device, after intervention with device, and follow up after an hour compared. Berg balance scale used to evaluate dynamic balance; wii balance board was used to measure static balance; and gait ability were measured by timed up and go test and 10-meter walk test. To analyze the results, a one-way repeated measures analysis of variance was implemented to compare the measurements. Results: The results showed that, after wearing the shoulder-back assistive device, the subjects' dynamic balance statistically significantly improved; no statistically significant difference was observed in static balance, although their balance ability was enhanced; and their increase in gait ability was statistically significant. Conclusion: This study proved that gait training combined with a shoulder-back assistive device positively impacted dynamic and static balance, gait of patients with stroke.

현대 아동교육을 위한 아동극 발전의 중요성은 주 5일제 수업이라는 교육환경 변화로 더욱 높아져 아동의 창의성 향상을 위한 교육적 기능 이외에도 아동들의 정서발달, 언어구사능력을 증진할 수 있는 기능이 있음을 인식하여 아동들을 위한 보다 적극적인 정책 마련이 필요하다. 요즘 스마트폰의 사용이 중고생은 물론 아동들에게까지도 널리 퍼져있는 만큼 아동극에 관련한 모든 정보전달이 가능한 앱을 개발하여 더욱 교육적이고 수준 높은 아동극의 활성화를 기대한다. 현재 아동극은 교육적, 정서적 기능의 가치와 역할을 잃은 채 아울렛이나, 백화점에서 주부고객들을 유치하기 위한 마케팅 전략의 도구로 이용되고 있다. 그들이 허울 좋게 만들어 놓은 아동전용극장은 쇼핑하는 동안 아이를 맡아주는 탁아소와 다를 바 없다. 아동교육기관과 부모들이 아동극에 대한 교육적 가치를 인식함과 더불어 더욱 효과적인 아동극 활성화를 위한 지원 정책이 필요하다. 앱 개발에 앞서 일반 소극장에서 이루어지는 아동극 공연과 관련한 교육적, 질적 차이에 관한 조사가 시급하며, 이에 따른 아동 전문극단에 대한 관리와 아동극에 대한 학술적 연구 또한 필요하다.

Objective: The purpose of this study was to examine the effects of real-time visual feedback weight shift training during golf swinging on golf performance. Design: Repeated-measures crossover design. Methods: Twenty-sixth amateur golfers were enrolled and randomly divided into two groups: The golf swing training with real-time feedback on weight shift (experimental group) swing training on the Wii balance board (WBB) by viewing the center of pressure (COP) trajectory on the WBB. All participants were assigned to the experimental group and the control group. The general golf swing training group (control group) performed on the ground. The golf performance was measured using a high-speed 3-dimensional camera sensor which analyses the shot distance, ball velocity, vertical launch angle, horizontal launch angle, back spin velocity and side spin velocity. The COP trajectory was assessed during 10 practice sessions and the mean was used. The golf performance measurement was repeated three times and its mean value was used. The assessment and training were performed at 24-hour intervals. Results: After training sessions, the change in shot distance, ball velocity, and horizontal launch angle pre- and post-training were significantly different when using the driver and iron clubs in the experimental group (p<0.05). The interaction time${\times}$group and time${\times}$club were not significant for all variables. Conclusions: In this study, real-time feedback training using real-time feedback on weight shifting improves golf shot distance and accuracy, which will be effective in increasing golf performance. In addition, it can be used as an index for golf player ability.

Objective: The aim of this research was to investigate the effects of functional electrical stimulation (FES) applied to the gluteus medius (Gm) and tibialis anterior (TA) during stair climbing in persons with stroke compared to FES applied to the TA only during stair climbing, and during stair climbing without FES in persons with stroke. Design: Cross-sectional study. Methods: Twenty subjects with stroke participated in this study. Subjects were included if: 1) they were diagnosed as stroke at least 6 months before; 2) had Mini Mental State Examination- Korean score of 24 or higher; 3) were able to climb a flight of 10 stairs independently (with or without walking aid). The patients walked 10 stairs 3 times with FES applied to the Gm and TA, only TA, or no FES. There was a 1-minute rest period between each bout. The assessments were made using the Timed Up & Down Test and the Wii Balance Board. Results: Stair climbing with FES applied to the Gm and TA was significantly faster than stair climbing with FES applied to the TA only and without FES (p<0.05). Stair climbing with FES applied to the Gm and TA exhibited significantly greater sway velocity than stair climbing without FES (p<0.05). However, maximal sway distances were not significantly different between groups. Conclusions: Stair climbing with FES applied to the Gm and TA can be an important component of a rehabilitation program for improving stair climbing ability in persons with stroke.

PURPOSE: The purpose of this study were to determine an intervention that involves proprioceptive exercises combined with cognitive task completion for adults with chronic ankle instability and to investigate the effects of the exercises on the static balance, dynamic balance, and ankle function of such individuals. METHODS: A total of 30 adults suffering from the aforementioned condition were randomly divided into experimental (n=15) and control (n=15) groups. The experimental group performed proprioceptive exercises in combination with cognitive tasks for 15 minutes in each session that was held three times a week for four 4 weeks, whereas the control group carried out only proprioceptive exercises. A Wii Balance Board, which enables examining the fluctuation area distance, and speed, was used to determine static balance; a Y-balance test kit was employed to measure dynamic balance; and the side hop, figure-of-8 hop, and square hop tests were conducted to ascertain ankle function. RESULTS: The results showed that the static balance, dynamic balance, and ankle function of both the experimental and control groups significantly improved. The participants were instructed to perform one-leg postural exercises with and without vision blocking for the affected leg. The experimental group showed more significant improvement than did the controls in terms of the fluctuation distance, speed, and area of static balance. CONCLUSION: In conclusion, although combined proprioceptive exercises and cognitive tasks were insufficient to enhance all types of balance among the subjects, it effectively reinforced their static balance.

PURPOSE: This study was conducted to investigate the effect of the virtual reality training (VRT) using 3-dimensional video gaming technology on spatiotemporal gait parameters in older adults. METHODS: The study participants were divided into two groups: the VRT group and the control group. Those in the VRT group were enrolled in a VRT, which was conducted for 60 min per day, two times a week, during the 6-week research. The Wii-Fit balance board game was used for the VRT intervention. The VRT consisted of 6 different types of games, namely, jogging, swordplay, ski jump, hula hoop, tennis, and step dance. A 3-dimensional TV was used for 3-dimensional display. Participants in both the groups received 3 sessions of fall prevention education, at the first, third, and fifth weeks. Their gait parameters were measured by using OptoGait. RESULTS: After 6 weeks of the VRT, the spatial gait parameters of the participants, that is stride length and step length, were significantly improved compared with those of the control group participants (p<0.05). The temporal gait parameters, such as velocity, cadence, stride time, and step time, also showed improvement after the completion of the VRT training (p<0.05). Both the temporal and spatial gait parameters of the VRT group participants showed improvement after 6 weeks of the program compared with those of the control group participants (p<0.05). CONCLUSION: The VRT using 3-dimensional video gaming technology might be beneficial for improving gait parameters to prevent falls among older adults.

Falling is one of the major public problems to the elderly, resulting in limitations of daily living activities. It can be induced by the functional loss of the balance ability and muscle strength in the elderly. It has been, however, not well investigated to suggest an effective methodology improving the balance ability and muscle strength for the prevention of the falling due to lack of information about the characteristics of the balance and muscle activations responded to the dynamic motions. The aim of the current study is, therefore, to identify the characteristics of the balance and muscle activations responded to the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. For that, a motion capture system with eight infrared cameras, surface electromyogram system and Wii Fit system with a customized variable unstable base were used and kinematic and kinetic data obtained from the systems were analyzed for five healthy male($24.8{\pm}3.3years$, $177.4{\pm}2.0cm$, $73.9{\pm}12.9kg$, $23.5{\pm}4.0kg/m$). The results showed that the characteristics of the balance and muscle activations were differently responded to between the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. These findings may indicate that customized dynamic motions should be applied to the training of the balance ability and muscle strength for the effective prevention of the falling. This study may be meaningful to providing basic information to establish a guideline improving effectively the balance ability and muscle strength.
