In this study, we analyzed the effects of game-based visual feedback training on postural balance control in young adults. We provided postural balance training for four weeks in fifth minute a day and three days a week using training system of postural balance based forceplate. We evaluated the ability of postural balance using balance SD(Biodex, medicalscience Inc., USA) for the validation of game contents based visual feedback training program. The results showed that postural stability and limits of stability were improved significantly before and after the training(p<0.05). Our study indicates that postural balance training of visual feedback based game could be adapted for improving postural balance. Also, for application of this game-based visual feedback training in older adults, we could develope of various game contents for disease types and conduct quantitative analysis and data collection of postural balance in the aged.

In this study, we examined the impact on balance ability and jump performance of soccer players with functional ankle instability using virtual reality based neuromuscular posture control fusion training. Soccer players were divided into 15 people of virtual reality-based neuromuscular posture control fusion training group and 15 people of common treadmill training group and performed for 30 minutes three times a week for 8 weeks. In order to evaluate the balance of ability, using biorescue, it measured surface area, whole path length, limit of stability. In order to measure jump performance, it measured counter movement jump with arm swing and standing long jump. The results showed the statistically significant difference in the balance comparison of surface area, whole path length, limited of stability and the jump performance comparison of counter movement jump with arm swing, standing long jump. As a result, virtual reality-based neuromuscular posture control fusion training was found to be more effective to improve its balance ability and jump performance than common treadmill training.

This study was conducted to compare the effect improving balance abilities of 3 balance training programs by randomized intervention trial. Study subjects were 29 female students recruited from a university in Gwanju, who allocated randomly to 3 intervention groups, aqua group(modified Halliwick 10 point program, N=10), visual bio-feedback balance training group(N=10), and balance-pad plus trampolin group(N=9). As the results of repeated musure ANOVA, Wilcoxon signed rank test, major research findings were as follows; 1. Regarding SI or BIEMG measured at upright posture on hard platform, bio-feedback group under the condition with opening both eye and aqua group under the condition with closing both eye showed signigicant improvement in balance ability, respectively. 2. Regarding SI or BIEMG measured at upright posture on soft platform, bio-feedback group under the condition with opening both eye and aqua group under the condition with closing both eye showed signigicant improvement in balance ability, respectively. 3. Regarding all 3 sensory ratios, bio-feedback group showed significantly higher increasement in them than other 2 groups. The results suggested that visual bio-feedback training program improve the all 3 sensory functions required for balancing, and aqua training modified from Halliwick 10 point program contribute to improve vestibular function principally.

In this paper, we analyzed the effects of game-based visual feedback training on postural balance control in young adults and older adults. We provided postural balance training by 23 young adults and 14 older adults and for four weeks in fifth minute a day and three days a week using IBalance(Cybermedic Inc., Korea). We evaluated the ability of postural balance using balance SD(Biodex, medicalscience Inc., USA) for the validation of game contents based on visual feedback training program. The results showed that postural stability and limits of stability of young adults and older adults were improved significantly before and after the training(p<0.05). Thus, the games of postural balance encouraged anterior, posterior, medial, lateral and multidirectional weight shifting regarding postural balance. Our study indicates that postural balance training of visual feedback based game could be adapted for improving postural balance. Moreover, we could develope of game contents for individuals and various ages for effective application of this game-based visual feedback training.

Objective : This study investigated the effect of intensive weight shift training (IWST) on the ability to balance in a sitting posture of children with spastic cerebral palsy (SCP). Methods : One child with spastic diplegia participated in this study for a total of 8 weeks using the ABA experimental design. For the pre-intervention period (A1), general physical therapy (GPT) for children with SCP was performed. The intervention period (B1 and B2), GPT and IWST were conducted for children with SCP, and GPT was conducted again for the post-intervention period (A'1 and A'2). Trunk control capacity was measured using the Korean Trunk Control Measurement Scale (TCMS-K) and Biorescue (RM Ingenierie, France). Results : All TCMS-K variables increased from A1 to B2, and decreased from B2 to A'2. The total area with limit of stability (LOS) increased from A1 to B2, and decreased from B2 to A'2. The ratio of the left/right (Lt/Rt) and anterior/posterior (Ant/Post) LOS area was closer to 1, meaning symmetry, in B2 than in A1. The ratio of the Lt/Rt LOS area decreased further from 1 in A'2 than in B2. The ratio of the Ant/Post LOS area was closer to 1 in A'2 than in B2. Conclusion : IWST had a positive effect on the improvement of balance in the sitting posture of a child with SCP. The results suggest that IWST might help to improve the balance abilities of children with SCP for independent sitting, postural control, and activities of daily living.

본 연구의 목적은 균형 훈련이 중추신경계 손상자들의 자세 조절 및 중추감각신경전도로에 미치는 영향을 규명하는데 있다. 연구대상자는 중추신경계 손상자로써 실험군 10명, 통제군 10명 등 총 20명을 선정하였으며, 실험군은 본 연구의 훈련 프로그램에 따라 12주간 force platform을 이용하여 균형훈련을 실시토록하였다. 자세조절 변인의 측정은 운동처치 전, 처치 후 8주 및 12주 후에 대상자들의 동적 및 정적 자세에서의 흔들림을 Dynamic Balance System을 이용하여 측정하였고, 체성감각 유발전위의 말초신경 근위부 유발전위$(N_9)$ 잠복기, 척수 유발전위$(N_{13})$ 잠복기, 뇌 유발전위 $(N_{20})$ 잠복기는 Neurotec을 이용하여 측정 분석한 결과 다음과 같은 결론을 얻었다. 1. 정적 자세 조절 요인의 경우, 좌우 흔들림과 전후 흔들림은 실험군에서 8주 후부터 유의하게 (p<.05) 감소하였고, 실험군이 통제군에 비해 운동처치 8주 및 12주 후에 각각 유의하게(P<.05, P<.01) 흔들림이 감소하였다. 2. 전후 이동면과 전후 기울기면에서 동적 자세 조절의 변화는 전후 이동면에서 좌우 흔들림과 전후 흔들림은 실험군에서 8주 후부터 유의하게 (P<.05) 감소하였으며, 실험군이 통제군에 비해 운동처치 8주 및 12주 후에 각각 유의하게 (P<.05, p<.01) 흔들림이 감소하였다. 3. 체성감각 유발전위의 잠복기 변화는 실험군과 통제군에 있어서 말초신경 근위부 유발전위$(N_9)$ 잠복기와 척수 유발전위$(N_{13})$ 잠복기가 다소 증가하였으나 유의한 차이는 나타나지 않았으며, 실험군에 있어서 뇌 유발전위 $(N_{20})$ 잠복기는 8주 후부터 유의하게 (P<.05) 증가하였다. 이상의 결과를 종합해 볼 때, 12주의 균형 훈련은 자세 조절에 있어서 전후와 좌우의 흔들림을 감소시킴으로써 정적인 상태나 동적인 상태에서의 자세 안정성을 증가시킬 수 있음을 시사하고 있다. 이는 자세 조절에 필요한 항중력근의 긴장성 수축을 유발시킬 뿐만 아니라 근육 긴장분포를 조절할 수 있다는 것으로 신경근 조절 기능의 향상을 의미하는 것으로 사료된다. 또한 뇌 유발전위 $(N_{20})$ 잠복기의 증가는 중추신경계의 감각기능의 신경학적 회복을 의미하는 것으로 중추신경계의 감각 운동통합에도 영향을 미쳐 운동기능의 향상을 기대할 수 이을 것으로 사료된다.
