본 연구는 불안정지지면 훈련을 통한 발목관절위치감각의 변화와 동요면적 변화간의 상관관계를 알아보고자 실시하였다. 건강한 성인 남녀 48명을 대상으로 무작위로 불안정지지면군(n=24)과 안정지지면군(n=24)으로 나누어 동일한 운동 프로그램을 적용하여 주 3회씩 6주 동안 실시하였다. 불안정지지면군은 균형운동 패드에서, 안정지지면군은 단단한 지면에서 운동을 실시하였다. 운동 전 후에 발목관절위치감각의 변화와 동요면적의 변화를 알아보았다. 그 결과, 불안정지지면군에서 발목관절위치감각 오차와 동요면적은 유의하게 감소하였다(p<.05). 그리고 불안정지지면군에서만 발목관절위치감각 오차의 변화량과 동요면적 변화량간의 유의한 상관관계를 보였다. 따라서 본 연구는 불안정지지면에서의 고유수용성감각 운동을 통해 발목관절위치감각 변화와 동요면적 변화간의 유의한 상관관계가 있음을 알 수 있었다.

Purpose: The purpose of this study was to compare the effects of the balance training on the stable and unstable supporting surfaces for the subjects with functional ankle instability. Methods: Twenty-nine subjects with functional ankle instability were randomly assigned to the stable group (n=14) and the unstable group (n=15). Balance training was conducted twenty minutes a day on the stable surface for the stable group and on the airostep for the unstable group three times a week for four weeks. Balance training program was consisted of ten steps by eye opened or closed and two or one leg standing. X-speed for transverse balance and Y-speed for longitudinal balance were measured with eye opened and closed in affected leg standing position. Results: There were significant improvements of balance ability in eye opened (p<.01) and eye closed standing (p<.01) in stable group. Unstable group also showed significant improvements of balance ability in eye opened (p<.01) and eye closed standing (p<.01). There were no statistical differences in the magnitude of improvement between the groups (p<.05). Conclusions: Based on such results, it can be said that balance training on the stable surface is effective as much as training on the unstable surface for the subjects with functional ankle instability.

Purpose : This research was conducted to see the correlation between sway speed and muscle activity for lower extremity of stroke patients through unstable surface training. Methods : A total of 60 patients were randomly divided unstable surface group (30 peoples) and stable surface group (30 people). Then they were asked to carry out the same exercise program for 6 weeks. The unstable surface group and stable surface group performed the exercise program on the balance mat and on the hard wood block. We checked the changes of sway speed and the changes in muscle activity for lower extremity. Results : The unstable surface group displayed significantly reduced sway speed, and improved muscle activity of lower extremity. There were significant correlation between change amount of muscle activity and sway velocity in Gastrocnemius, Biceps femoris during unstable surface training(r=.373, p<.05)(r=.369, p<.05). And there were not show significant differences during stable surface training. Conclusion : Judging from this, we can have knowledge that the correlation between increase of muscle activity and decrease of sway velocity for Gastrocnemius, Biceps femoris in the unstable surface training.

The purpose of this study was to determine the effect of the changes that occur in the leg muscle activity of unstable surface with different levels of air pressures. Three groups of college students have been placed randomly on unstable surfaces with different air pressures at group 1.0 psi ($n_1$=36), group 1.4 psi ($n_2$=40), and group 1.8 psi ($n_3$=40). Using surface electromyography, the recruitment of the tibialis anterior, peroneus longus, and the gastrocnemius was measured. Maximal voluntary isometric contraction was measured at the different air pressures based on the manual muscle test, then normalizing the value to %maximal voluntary isometric contraction (%MVIC). The tibialis anterior muscle activity was significant change from the unstable surface with difference levels of air pressures between group 1.0 psi and 1.8 psi and between group 1.4 psi and 1.8 psi. peroneus longus muscle activity was significant changes in muscle activity occurred between 1.0 psi and 1.4 psi group and between 1.0 psi and 1.8 psi group. Gastrocnemius muscle activity was significant change in muscle activity occurred between 1.0 psi and 1.4 psi group and between 1.0 psi and 1.8 psi group. In conclusion it identify that 1.0 psi group is most effective on muscle activity than the other groups. These suggest that the rehabilitation or strengthening of patients with ankle injuries, balance exercise with low air pressure like 1.0 psi can be more effective.

The purpose of this study was to determine the effectiveness of sit-to-stand training on unstable surfaces in individuals with stroke. Nineteen subjects with chronic stroke were divided into two groups: an experimental group (10 subjects) and a control group (9 subjects). They received 30 minutes of Neuro-developmental therapy (NDT) treatment, and sit-to-stand exercise for 15 minutes three times a week for four weeks. During the sit-to-stand training, the experimental group performed on an unstable AIREX balance pad, but the control group performed on a stable surface. Balance ability and weight-bearing distribution during quiet standing were measured before and after training period using the 7-item Berg balance scale-3P (BBS-3P) and the Five-times-sit-to-stand test (FTSST). In addition, the muscle strength of the knee extensor was evaluated before and after the training period. The results were as follows: 1) The weight-bearing distribution forward of the affected leg, increased significantly in the experimental group after the four-week intervention (p<.05), 2) The 7-item BBS-3P and FTSST increased significantly in the experimental group after the four-week intervention (p<.05), 3) The knee extensor muscle strength in both groups increased significantly after the four-week intervention (p<.05). In conclusion, the results of this study did not show that the sit-to-stand training on an unstable surface was more effective than on a stable surface. However, the results suggested that sit-to-stand training is effective in the balance training of stroke patients.

Purpose : This study was conducted to examine the effects of unstable surface training and galvanic vestibular stimulation on balance and proprioception. Methods : 4-week training was applied to 40 normal adults in their twenties (unstable surface training group 10, galvanic vestibular stimulation group 10, unstable surface training and galvanic vestibular stimulation group 10, control group 10). Balance and proprioception was measured before the experiment, after two weeks, and after four weeks. Repeated ANOVA was used for balance and proprioception analysis. Results : As a result of repeated ANOVA on balance changes in double support, a significant difference was found in open sight in interaction among groups and periods (p<0.05). As a result of repeated ANOVA on balance changes in double support, there was a significant difference in closed sight and interaction among groups and periods (p<0.05). As a result of repeated ANOVA on balance changes in proprioception, there was no statistically significant difference in interaction among groups and periods. Conclusion : In conclusion, both unstable surface training and galvanic vestibular stimulation had positive effect on balance control and proprioception improvement, and their excellence was not greatly different. Thus, it is possible to use unstable surface training and galvanic vestibular stimulation for physical therapy intervention to improve balance and proprioception. Since the results showed that simultaneous application of two methods had greater effects on difference compared with a single application, it is suggested to use this intervention in the clinical field.
