Purpose: This study was done to suggest directions for developing exercise interventions for fall prevention in the elderly in Korea in the future, Method: Twenty five articles for fall prevention exercises were reviewed and analyzed. Result: $84.0\%$ of subjects were older adults age 65 and older living in the community. The most frequently performed interventions were lower limb strength and balance exercises together $43.3\%$, group exercise $70.0\%$, exercise 3 times/week $60.0\%$, 60 min per session $36.7\%$, duration of 12 weeks and 1 year $23.3\%$ each. The most frequently used outcome variables were static balance $84.0\%$, lower limb muscle strength $72.0\%$, dynamic balance $56.0\%$, and falls $56.0\%$. The effect of exercise interventions on fall prevention was inconclusive. Lower limb strength exercises with resistance were effective for increasing muscle strength. Balance exercises with various movements for balance were effective for increasing balance. Conclusion: Exercise interventions for fall prevention is recommended for older adults with risk factors of falling. The desirable type of exercise intervention is lower limb strength and balance exercise together.

Objective: This study focused on subacute stroke patients who were asked to kick a ball while walking on a treadmill. The aim of the study was to determine the effect of a body weight-supported treadmill training (BWSTT) combined with ball-kicking on muscle strength, balance, and gait. Design: Single blind, randomized controlled trial. Methods: Twenty stroke patients who volunteered to participate in this study were randomly assigned to either the BWSTT combined with ball-kicking (BWSTT-BK; 10 participants) group or the BWSTT group (10 participants). Participants in the BWSTTBK group performed treadmill walking combined with simultaneous ball-kicking for 30 minutes daily for 5 weeks. Participants from the BWSTT group performed only treadmill walking. The muscular strength, balance, and gait ability were measured before and after the 5-week training. To assess for muscular strength, a digital muscle tester was used to measure hip flexor, knee extensor, and dorsiflexor strength. To assess for balance, the Berg Balance Scale (BBS) and Timed Up and Go Test (TUG) was used. To assess for gait, the 10 meter walk test (10MWT) and Functional Gait Assessment (FGA) was used. Results: The BWSTT-BK group showed significantly improved muscular strength, balance, and gait according to BBS, TUG, 10MWT, FGA, and digital muscle testing scores compared to the BWSTT group (p<0.05). In addition, within-group comparison showed significant improvement in all variables (p<0.05). Conclusions: These findings suggest that BWSTT-BK results in more favourable outcomes for stroke patients. Therefore, BWSTT-BK may be useful for the recovery of gait ability of stroke patients.

Purpose: This study investigated the effects of progressive resistance task-oriented strengthening exercises (PRTSE) on the strength of the lower extremities, balance, and activities of daily living (ADL) of patients following a stroke. The purpose of the study was to provide fundamental data regarding the use of PRTSE with stroke patients. Methods: Twenty stroke patients were randomly divided into an experimental group (n = 10) who took part in PRTSE and a control group (n = 10) who performed general rehabilitation exercises. Both groups performed their respective exercises for 30 minutes five times a week for four weeks. The strength of their lower extremities was measured using a hand-held dynamometer. The balance of the participants was assessed using a Berg balance scale. The modified Barthel index was conducted to measure ADL. A paired t-test was performed to compare within-group changes before and after the PRTSE. Differences between the experimental and the control groups were analyzed using an independent t-test. For all tests, the level of statistical significance was α = 0.05. Results: After the exercises, there was a significant within-group change in the strength of lower extremities, balance, and ADL in the experimental group and the control group (p < 0.05). There was also a significant between-group difference in the strength of lower extremities after the intervention (p < 0.05). Conclusion: General rehabilitation is commonly applied as a treatment for stroke patients and is relatively effective. The application of PRTSE may be useful in such patients, considering its effects on the strength of lower extremities, balance, and ADL.

PURPOSE: This study measured the impact of a 12-week fall-prevention exercise program on balance, ambulatory ability, lower limb strength, and psychosocial characteristics in older adults diagnosed with dementia. METHODS: The participants comprised 31 older adults (9 men, 22 women) diagnosed with Alzheimer's or vascular dementia at a long-term care hospital located in Gunsan City. A fall-prevention exercise program was provided to the experimental group, while the control group was only provided with instruction and materials related to the fall-prevention exercise program. The participants were evaluated before the intervention, 6 weeks after the intervention, and 12 weeks after the intervention on static and dynamic balance abilities (using Timed Up and Go test: TUG, Tinetti-balance scale, one-leg standing test: OLS), gait (Tinetti-balance scale, 6-minute walk test: 6MWT), lower limb strength (sit to stand test; STS), and psychosocial characteristics (Short Form 36 Health Survey-Korean version, Korean Mini-Mental State Exam). RESULTS: An independent samples t-test and repeated measures analysis of variance were used for the statistical analysis. There were statistically significant improvements after the intervention (p<.05) in dynamic balance abilities (TUG and OLS using the left foot), gait (6MWT), and lower limb strength (STS) for the experimental group, but not for the control group. No difference was seen in psychosocial characteristics. CONCLUSION: Older adults with dementia who participated in the fall-prevention exercise program showed significant improvements in their static and dynamic balance abilities, lower limb strength, and ambulatory ability after the intervention.

PURPOSE: This study examined the effects of Robot Tilt-table Training (RTT) on the lower extremity strength, balance, gait, and satisfaction with rehabilitation, in patients with subacute stroke (less than six months after stroke onset), and requiring intensive rehabilitation. METHODS: A total of 29 subacute stroke patients were divided into an RTT group (n = 14) and a Body Weight Support Treadmill Training (BWSTT) group (n = 15). The mean age of patients was 62 years. RTT and BWSTT were performed for four weeks, three times a week, for 30 minutes. Isometric strength of the lower extremities before and after intervention was compared by measuring the maximal voluntary isometric contraction of the lower extremity muscles. To compare the balance function, the center of pressure (COP) path-length and COP velocity were measured. Timed Up & Go test (TUG) and 10 Meter Walking Test (10 MWT) were evaluated to compare the gait function. A satisfaction with rehabilitation survey was conducted for subjective evaluation of the subject's satisfaction with the rehabilitation training imparted. RESULTS: In the intra-group comparison, both groups showed significant improvement in lower extremity strength, balance, gait, and satisfaction with rehabilitation, by comparing the parameters before and after the intervention (p < .05). Comparison of the amount of change between groups revealed significant improvement for all parameters in the RTT group, except for the 10 MWT (p < .05). CONCLUSION: Both groups are effective for all variables, but the RTT group showed enhanced efficacy for variables such as lower extremity strength, balance, gait, and satisfaction with rehabilitation, as compared to the BWSTT group.

Purpose : The purpose of this study is to verify the effect of selective muscle strengthening of the knee joint extensor muscles using a pressure biofeedback unit to improve knee extensor strength and the balance ability of total knee replacement patients. Through this, we tried to provide clinical information. Methods : In this study, 12 patients with total knee replacement were recruited from a rehabilitation hospital. They were divided into two groups: a feedback group (n=6) and a control group (n=6). All patients received 30 minutes of continuous passive motion and leg-strengthening exercises for 15 minutes five times a week for two weeks. Subjects performed knee extension exercises with or without biofeedback units in the sitting position. The knee extensor strength and balance ability were measured before and after exercise. Knee extensor strength was measured by Biodex system 3 and balance ability was measured by Balancia software. Results : Both the experimental group and the control group showed a significant difference in the muscle strength of the knee joint extensor muscles after intervention (p<.05). In comparison, the experimental group showed a significant difference than the control group (p<.05). Both the experimental group and the control group showed a significant difference in the velocity average, path length, area 95 % center of pressure (COP), weight distribution, five times sit to stand test (FTSST) after intervention. In comparison, the experimental group showed a significant difference in velocity average, area 95 % COP, and FTSST than the control group (p<.05). Conclusion : In order to strengthen the knee extensor muscle and improve the balance ability in total knee replacement patients, it is necessary to consider providing pressure biofeedback unit during leg strengthening exercises.

PURPOSE: This study investigated the immediate effects of gluteus medius strengthening training and relaxation therapy on the static balance, muscle strength asymmetry, and proprioception. METHODS: In this research, 38 healthy adults were assigned randomly to strengthening groups (SG) and relaxation groups (RG). The static balance, muscle strength asymmetry, and proprioception were measured as a pre-measurement. The same measurements were performed after the intervention and follow-up. An independent sample t-test was used to compare each group, and one-way repeated ANOVA was used to compare the changes within the group. RESULTS: In the static balance, the comparison between groups SG was more significant than RG, and only SG showed significant differences in the intra-group comparisons. There was no significant difference in muscle strength asymmetry between SG and RG. On the other hand, the comparison within the group revealed only SG to be significant. In proprioception, SG produced more significant results than RG, and only SG had significant values in the within-group comparison. CONCLUSION: Strengthening training affects the changes in static balance, muscle strength asymmetry, and proprioception.
