Purpose: This study aimed to investigate the effects of ankle stretching with intrinsic muscles on ankle range of motion, static and dynamic balance, and gait speed in chronic stroke patients. Methods: The participants were 20 chronic stroke patients, divided into two groups, 10 in the ankle stretching with intrinsic muscles group and 10 in the slant board exercise group. Both groups performed their respective interventions once daily, with three sets per session, five times a week for four weeks. Ankle range of motion, dynamic and static balance, and gait speed were measured before and after the intervention. An independent t-test was used to compare the results between the two groups before and after the intervention. Results: Both groups showed significant improvements in ankle range of motion, dynamic and static balance, and gait speed after the intervention (p < .05). The ankle stretching with intrinsic muscles group showed more significant improvements in ankle range of motion, dynamic and static balance, and gait speed after the intervention compared to the slant board group (p < .05). These results suggest that ankle stretching with intrinsic muscles may be more effective than the slant board for certain outcomes. Conclusion: Ankle stretching with intrinsic muscles is effective in improving ankle range of motion, dynamic and static balance, and walking speed.

This study investigated the effect of community-based health intervention program to improve metabolic disease in Jeju island. There were 50 obese local residents in the experimental group (body mass index, $BMI{\geq}25kg/m^2$). They participated in cooking therapy with nutrition education (4 times), exercise program with proprioceptive neuromuscular facilitation (PNF) and stretching training (9 times), and alternative medicine program with healing touch massage (3 times) during a 3-week period. To evaluate the effectiveness of the program, body composition, blood lipid profiles, blood glucose, and waist circumference were assessed before and after the intervention program. After the program, the value of total cholesterol (TC), glycosylated hemoglobin (HbA1C), diastolic blood pressure, percent body fat, and waist circumference were decreased, and became the normal value. Especially, HbA1C, percent body fat, and waist circumference were significantly decreased (P<0.001) in the experimental group, while HbA1C, percent body fat, and waist circumference were significantly increased (P<0.001) in the control group (N=50), who had no intervention. Our results suggest that metabolic syndrome associated markers need intervention program for improving them. In conclusion, although this study did not analyze the effect of the health intervention program and cooking therapy separately, considering the result of this 3-week, short term program, the effect will be more profuse if cooking therapy and exercise program were performed concurrently.

Purpose : When the pliability of the Lumbar is degraded, the kinesiology function undergoes an influence and it receives an overload. Finally, it is connected with a Lumbar muscular injury. When it does the regular exercise treatment the lumbago patient the balance and function of changeover are improved. The purpose of this study is to review of effect of the PNF application for lumbago patient Methods : By using internet, we research the PubMed, Science Direct, KISS, DBpia and the article on the effect of PNF. We selected the article between 1970 and 2007. Key words were low back pain, lumbago, PNF. Results : PNF is a therapeutic exercise for central nervous system(CNS) patient and the peripheral nervous system(PNS) patient and it is widely applied from sports medicine in the last. According to research of the Jung Young Jo(2007) and Han Kou Soo(2002), PNF technique improves the pain and a condition of the lumbago patient. And the affection balanced change and dynamic balance change and spontaneous movable scope are improved. And it improved to daily life activity. According to research of Moore and Hutton(1980), Lee Kyoung Hye(1999), PNF stretching where it is one of muscular relaxation is good in lumbar muscle fascia ache solutions, and PNF stretching that muscle is relaxed and increases ROM by Reflective system of the vertebra. These researches is relation all each other. it have appeared many report of research about Pliability, muscular power, balance, mobility improve ADL movement of attendance ability and functional action improved excise therapy put effect about lumbago patient recently, it have appeared research about therapy of lumbago patient through PNF. But PNF technique is not application about lumbago patient in clinic, therefore also it is not enough for case study about this therapy. Conclusion : PNF improve combination operation of muscle, inconvenience decrease from daily life activity, ROM(range of movement) of lumbar is increase and Lumbago reduce. So we suggest that PNF will be applies on the lumbago patient and must do a many research.

Purpose: The purpose of this study was to investigate the effects of three relaxation techniques, namely, Static Stretching Exercise (SSE), Eccentric Contraction Exercise (ECE), and Suboccipital Muscle Release (SMR) on the flexibility and balance of the lower limb in adults with hamstring shortening. Methods: The participants were 45 adults in their 20s with hamstring shortening. They performed three exercises (i.e., SSE, ECE, and SMR) for two weeks. We measured flexibility, muscle tone and stiffness, proprioception, and balance before and after the intervention, applying each relaxation technique. Data were analyzed using two-way repeated measures analysis of variance (ANOVA). The significance level was set at α=0.05. Results: Flexibility increased in the SSE, ECE, and SMR groups, with the SSE group showing the greatest improvement. Muscle tone and stiffness decreased in all groups, with the ECE group exhibiting the highest reduction. Proprioception increased in the SSE, ECE, and SMR groups, with SSE demonstrating the greatest enhancement. Balance also increased in all groups, with the ECE group showing the most pronounced improvement. Conclusion: Overall, all three relaxation techniques for hamstring shortening resulted in improved flexibility, muscle tone and stiffness, proprioception, and balance of the lower limb in adults with hamstring shortening. The findings of this study underscore the importance of selecting an appropriate technique according to the purpose of treatment and the condition of the patient.

The purposes of this study were to examine the normal lumbar proprioception and identify the effect of vision and proprioception on lumbar movement accuracy through measuring a reposition error in visual and non-visual conditions and to provide the basic data for use of vision when rehabilitation program is applied. The subjects of this study were 39 healthy university students who have average physical activity level. They were measured the ability to reproduce the target position(50% of maximal range of motion) of flexion, extension, dominant and non-dominant side flexion in visual and non-visual conditions. Movement accuracy was assessed by reposition error(differences between intended and actual positions) that is calculated by the average of absolute value of 3 repeated measures at each directions. The data were analysed by paired samples t-test, independent samples t-test, and repeated measures ANOVA. The results were as follows : 1. Movement accuracy of flexion, extension, dominant side flexion, and non-dominant side flexion was increased in visual condition. 2. There were no differences in the lumbar movement accuracy between sexes in visual and non-visual conditions. 3. In non-visual condition, the movement in coronal plane(dominant and non dominant side flexion) is more accurate than that in sagittal plane(flexion and extension). 4. In non-visual condition, there were no differences in the lumbar movement accuracy between dominant and non-dominant side flexion. In conclusion, this study demonstrates that the movement is more accurate when the visual information input is available than proprioception is only available. When proprioception is decreased by injury or disease, it disturbs the control of posture and movement. In this case, human controls the posture and movement by using visual compensation. However it is impossible to prevent an injury or trauma because most of injuries occur in an unexpected situation. For this reason, it is important to improve the proprioception. Therefore, proprioceptive training or exercise which improve the ability to control of posture and movement is performed an appropriate control of permission or interception of the visual information input to prevent an excessive visual compensation.

Purpose: This study compares the effects of treadmill gait training accompanied by visual feedback and general treadmill gait training on the gait and balance ability of patients with chronic stroke. Methods: A total of 11 patients with chronic stroke were randomly divided into either the treadmill gait training accompanied by visual feedback group (six patients) or the general treadmill gait training group (five patients). The gait and balance ability of the two groups were measured before and after the interventions using the functional reach test, the Timed Up and Go (TUG) test, Berg's balance test, and the Biodex balance test. The treadmill gait training accompanied by visual feedback group performed the exercise under the supervision of a therapist after first being provided with a hat and a goal that was devised for the purpose of providing visual feedback information. The interventions were applied to the respective groups for four weeks. For the statistical analysis, we conducted a Mann-Whitney test to compare the results between the two groups. Additionally, the Wilcoxon test was used to compare the results from before and after the intervention in each group. Results: The treadmill gait training accompanied by visual feedback group showed a significant difference in terms of the functional reach test after the intervention when compared to the general treadmill gait training group (p<0.05). Although there was no significant difference, the treadmill gait training accompanied by visual feedback group showed a larger improvement in the TUG test, Berg's balance test, and the Biodex balance test than the general treadmill gait training group (p>0.05). Conclusion: The results of this study suggest that treadmill gait training accompanied by visual feedback can be used as a beneficial intervention scheme for the recovery of the gait and balance ability of patients with chronic stroke.

Purpose: The purpose of this study was to investigate the differences in muscle thickness and ground reaction force of the vastus medialis oblique and vastus lateral oblique muscles during squats at ankle angles of toe 0°, toe in 10°, and toe out 10°. Methods: In this study, 9 male and 17 female students in their 20s participated in a randomized controlled trial and were compared according to the ankle angles of toe 0°, toe in 10°, and toe out 10°. To determine the reliability and measurement of muscle thickness according to ankle angle using ultrasound equipment and muscle thickness, the participants' ankle angles-toe 0°, toe in 10°, and toe out 10°-were measured three times at the vastus medialis oblique and vastus lateralis oblique muscles during squats. At the same time, the maximum vertical ground reaction force was measured with a force plate. A total of three measurements were taken and averaged, and two minutes of squat movements were assessed between ankle angles to prevent target action. Results: The results of this study illustrated that the reliability of the vastus medialis oblique muscles and vastus lateralis oblique muscles in ankle angle was high. The difference in muscle thickness was significantly greater in comparing the toe out 10° angle with the toe 0° angle than between toe in 10° and toe out 10° in vastus medialis oblique and vastus lateralis oblique (p < 0.05). There was no statistically significant difference between the ankle angle of toe 0° and toe in 10° (p > 0.05). The maximum vertical ground reaction force was significantly greater at toe out 10° than at the ankle angle of toe 0° and toe out 10° and between toe in 10° and toe out 10° (p < 0.05). There was no statistically significant difference in the comparison between toe 0° and toe in 10° (p > 0.05). Conclusion: Squatting at an ankle angle of toe out 10° increases the dorsi flexion; thus, the stability of the ankle and the thickness of both oblique muscles increased to perform more effective squats. In addition, as the base of support widens, it is thought that the stability of the posture increases so that squat training can be performed safely.

Background: Fall-related injuries in older adults are a major health problem, and the risks and mechanisms of these injuries should be affected by race, culture, living environment, and/or economic status. Objects: Research articles have been systematically reviewed to understand fall-related injuries in older adults in South Korea. Methods: 128 published research papers have been found through the Korea Citation Index and the Korean Studies Information Service System, and reviewed in various perspectives, including incidents, fall death rates, medical costs, causes, injury sites and types, locations where falls occurred, prevention strategies, scholarly fields interested in fall injuries, and the role of physical therapy. Results: Fall-related injuries were found to be more common in women than in men, and the number of incidents increased with age, with the highest rate found in individuals over 85 years old. Risk of fall injury was associated with education level, comorbidities, and fear of falling. Common places where falls occurred included the bathroom, living room, stairs, and hallway. Common types of injury included bruises, fractures, and sprains in the lower extremities. Intervention strategies included exercise programs, education, and protective clothing. Scholarly fields interested in fall-related injuries in older adults included medicine, nursing, physical therapy, occupational therapy, physical education, pharmacology, oriental medicine, biomedical engineering, design, clothing, and textiles. Physical therapy intervention using proprioceptive neuromuscular facilitation has been used to improve one's balance. Conclusion: Any movement during the activities of daily living can lead to a fall. Physical therapists are highly educated to analyze human movements and should be involved in more research and practices to solve fall-related injuries in older adults.
