The purpose of study was to evaluate effects of a trunk muscle strength training on sitting balance of children with spastic cerebral palsy. Five individuals with spastic cerebral palsy(three females. two males; mean aged 6.6) participated three times a week over 6 weeks. Five individuals with spastic cerebral palsy(three females. two males; mean aged 7.0) who did not receive strength training served as control. BPM(Balance Performance Moniter) was used to measured sitting balance and EMG(electromyograph, NORAXON, USA) was used to measured activities of abdominal and erector spine muscle. The obtain result are as follows. 1. The result of this study were following that maximum perturbation area and perturbation velocity were significantly reduced strength training group compared with control group(p<.05). 2. The result of this study were following that maximum perturbation area and perturbation velocity were significantly reduced after strength training compared with pre strength training in strength training group(p<.05). 3. The result of this study were following that maximum perturbation area and perturbation velocity were not significantly reduced at interval of six week in control group(p<.05). 4. The result of this study were following that abdominal muscle activity was significantly increased strength training group compared with control group(p<.05). 5. The result of this study were following that erector spine muscle activity was significantly increased strength training group compared with control group(p<.05). 6. The result of this study were following that abdominal muscle activity and erector spine muscle were significantly increased after strength training compared with pre strength training in strength training group(p<.05). 7. The result of this study were following that abdominal muscle activity and erector spine muscle were not significantly increased at interval of six week in control group(p<.05). In conclusion, the result of this study suggest that improved sitting balance and increased activities of trunk muscle by trunk strength training in spastic cerebral palsy. The result was proposed that therapeutic approach of spastic cerebral palsy with impaired sitting balance should use trunk strength training.

Objective: The purpose of this study was to determine the effects of Augmented Reality-based Postural Control (ARPC) training on balance and gait function in patients with stroke. Design: Single-blind randomized controlled trial. Methods: Twenty participants who experienced a stroke were enrolled in the study and randomly assigned to the ARPC (n=10) or control group (n=10). Subjects in both groups received conventional physical therapy for 60 min per session, 5 days per week, for 4 weeks. In addition, subjects in the ARPC group received ARPC training for 30 min per day, 3 days per week, for 4 weeks. The participants watched established normal postural control patterns on a head-mounted display and repeated the movements in ARPC training. Outcome measurements were assessed using the Berg Balance Scale (BBS) and 10-Meter Walk Test (10MWT) before and after 4 weeks of training. Results: Of the 20 randomized participants, only 18 completed the 4-week training program. The ARPC group showed significant improvement in the BBS and 10MWT after training (p<0.05). Meanwhile, the control group did not exhibit improvement in either variable. In addition, the ARPC group showed significantly greater improvement than the control group in the 10MWT (p<0.05), whereas no significant difference was observed between the groups for the BBS. Conclusions: The results of this study confirmed the benefits of ARPC training on dynamic balance and functional gait ability. Additionally, this study may provide evidence supporting the use of an ARPC training program for improving balance and gait ability in patients after a chronic stroke.
Purpose: The purpose of this study is to investigate the effects of interference current therapy and laser therapy on functional recovery after total knee arthroplasty by measuring the Berg balance scale and range of motion. Methods: Subjects were 30 patients who were admitted to G Hospital after total knee arthroplasty. They were randomly assigned to experimental group I in which interference current therapy was applied (n=10), experimental group II in which laser therapy was applied (n=10), or the control group (n=10). The Berg balance scale and range of motion of the subjects were measured before, after 2 weeks, and after 4 weeks of therapy. Results: There was a statistically significant change (p<0.05) in the Berg balance scale and range of motion before and after therapy intervention among the laser therapy group and the interference current therapy group. There was also a significant change between the groups in the Berg balance scale and range of motion. Tukey's post hoc comparison showed a statistically significant difference between the control group and experimental group I and between the control group and experimental group II (p<0.05). Conclusion: The application of interference current therapy and laser therapy resulted in a significant change in both the Berg balance scale and range of motion among patients with total knee arthroplasty. The findings of this study can be used as preliminary clinical data in evaluating functional recovery in patients with total knee arthroplasty in a post-clinic setting.
Purpose: The purposes of this study was to develop a comprehensive community-based fall prevention program and to test the effects of the program on the muscle strength, postural balance and fall efficacy for elderly people. Methods: The design of this study was a nonequivalent control group pretest-posttest design. There were 28 participants in the experimental group and 29 in the control group. The program consisted of balance exercises, elastic resistance exercises and prevention education. The program was provided five times a week for 8 weeks and each session lasted 90 minutes. Data were analyzed using ${\chi}^2$-test, independent t-test and paired t-test using the SPSS program. Results: Muscle strength of the lower extremities, postural balance and fall efficacy scores significantly improved in the experimental group compared to the control group. Conclusion: These results suggest that this program can improve lower extremity muscle strength, postural balance and fall efficacy in elders. Therefore, this program is recommended for use in fall prevention programs for elders living in the community.

Purpose : The purpose of this study was to evaluate the effect of Whole body vibration exercise(WBVE) in patient with chronic stroke. Methods : Thirty patients were divided into two groups by randomly experimental group(14 subject) and control group(16 subject) in a single blinded, randomised study. experimental group was conducted for the 6-weeks WBVE program and had a structured exercise program for 16 minutes, 5 days per week and control group was conducted for the shame exercise program. Outcome variables included the knee extensor strength, Berg balance scale, Timed up and go test at 0 and 6 weeks. Results : The experimental group tended to improve more than the control group in balance(Berg balance scale) and walking ability(Timed up and go test). There were no trends in differences in change scores by the knee extensor strength. Conclusion : WBVE program may be helpful to improve knee extensor strengthening, dynamic balance and walking ability for patients with chronic patients.
Purpose: The purpose of the current study was to examine the effects of electromyography (EMG)-biofeedback training on lower extremity muscle activity and balance of patients with total knee replacement (TKR). Methods: Subjects were randomly allocated to two groups: experimental and control group. Subjects in the experimental group (n=10) were provided with quadriceps setting exercise by EMG-biofeedback (QSE+BF) and those in the control group were provided with QSE. Subjects in both groups were provided with the respective training programs for 20 minutes per session, five times per week, for a period of six weeks. To test significance, data analysis was performed using repeated-ANOVAs. Results: Statistically significant differences in muscle activity of the rectus femoris muscle and the vastus lateralis, and dynamic balance ability were observed in the experimental group, compared with the control group. In comparison of the muscle activity of the rectus femoris muscle and the vastus lateralis, and dynamic balance ability between different training periods within the groups, both groups showed statistically significant differences. Conclusion: EMG-biofeedback training is effective in improving lower extremity muscle activity and balance ability of patients with TKR, and should be effective in patients with other diseases.
The purposes of this study were to test the effect of balance training and environmental enrichment on motor performance after traumatic cerebellar injury in the rat. Traumatic cerebellar injury was induced by weight drop model and after operation they were housed in individual standard cages for 24 hours. Twenty two Sprague-Dawley rats were randomly assigned into control and experimental groups. The control group was housed in standard cage for 7 days. The experimental group I was housed in standard cage after balance training for 7 days. The experimental group II was housed in environmental enrichment cage after balance training for 7 days. Vestibular drop test and tilting plane test was examined at preoperation, on 1st day after operation and 7th day after operation to the rats. The results of this experiment were as follows: 1. In motor behavioral test, at preoperation and on 1 day after operation, the outcomes were not different among the groups. But on 7th day after operation, the outcomes of group I were better than that in control group, and group II were better than group I. These results suggest that behavioral motor outcome by simultaneously application of balance training and environmental enrichment in traumatic cerebellar injured rats were more improve than that by just balance training.
Purpose: The purpose of this study was to examine the effect of balance taping procedures on lower back pain. Method: This study is nonequivalent control group pretest-posttest design of quasi-experimental study. From May in 2004 to July in 2004, the research was done for females who have lower back pain in Gyeonggi province. Experimental group was 37, and control group was 36. The degree of lower back pain and that of the pain on activity of daily living(ADL) were each measured two times. Result: In the experimental group, the lower back pain score before taping was 6.38, that of 1 hour after the taping applied was 3.27. The lower back pain score of experimental group was significant statistically decreased and that of control group was almost not changed. Moreover, the pain score on ADL was statistically decreased in experimental group. Therefore balance taping is effective to reduce lower back pain and to improve ability of ADL. Conclusion: This study supports that balance taping may benefit individuals with lower back pain and balance taping therapy can be used as an independent nursing intervention. However, a larger study is in need to provide definite evidence and to determine long-term effects.

PURPOSE: The purpose of this study was to identify the effects of neck stabilization exercise combined with trunk stabilization exercise on balance and gait function in patients with chronic stroke. METHODS: Twenty-two chronic stroke patients were included in this study. The experimental group subjects (n = 11) performed neck stabilization (15 min) and trunk stabilization (15 min) exercises, while the control group subjects (n = 11) performed trunk stabilization exercise only for 30 min. Before and after the intervention, the subjects underwent static balance and gait testing. RESULTS: The 95% confidence ellipse area, center of pressure (COP) path length, and COP average velocity were significantly lower in both groups after the intervention compared to before intervention (p < .05). The average stance force on the affected side increased significantly in both groups after the intervention (p < .05). The changes in the static balance variables were larger in the experimental group than in the control group. The cadence, gait velocity, and single leg support increased significantly in both groups after intervention (p < .05). The changes in the gait variables were larger in the experimental group than in the control group. CONCLUSION: Trunk stabilization is a beneficial intervention, but the combination of neck stabilization with trunk stabilization is a more effective method to increase the gait and static balance in chronic stroke patients.
