The Goal of this study was to assess the effect of aerobic exercise on cognitive function of elderly people. The participants' cognitive functions were measured before exercise. Exercise was practiced three times a week for nine weeks. The aerobic exercises consisted of warm-up exercises for five minutes followed by cycling for 30 minutes. The exercise intensity was set to 65%~75% of the intensity for the maximum heart rate(220-age). The control group did not perform any exercises. The subjects' cognitive functions were measured nine weeks later. In the aerobic exercise group, between before and after the exercises, significant increases appeared in total K-MMSE scores and scores of some sub items comprising memory registration, concentration and calculation abilities but not in other items. In the control group, no significant differences appeared in any items between before and after the experiment. In a comparison between the aerobic exercise group and the control group, significant differences appeared in total K-MMSE scores and scores of two sub items comprising concentration and calculation abilities but not in other items(p<.05). Aerobic exercises were effective in the improvement of cognitive functions and among sub items of cognitive functions, concentration and calculating abilities were improved. Aerobic exercises performed by elderly persons are considered to be effective in improving cognitive functions.

The purpose of this study was to assess the effects of lower extremity resistance training using elastic bands on balance in elderly people. Eight elderly persons each were randomly assigned to a test group(resistance exercise group, REG) or a control group(CG). FRT and TUG test were used to compare balance before and after exercise. Exercise programs were implemented three times a week for 40 minutes for nine weeks. They did warm-up exercise for 5 minutes and then lower extremity resistance exercise using elastic bands for 30 minutes. And then they did cool-down exercise for 5 minutes. TUG and FRT significantly decreased but in the control group it did not significantly decrease. In comparison between the groups, TUG and FRT significantly reduced in the resistance exercise group compared to the control group. Lower extremity resistance training using elastic bands performed by elderly persons are considered to be effective in improving balance.

This study was conducted to evaluate the effect of the exercise on elderly balance ability by using hippotherapy and therapeutic ball exercise. 10 patients were assigned to the hippotherapy group and they got with 30 minutes of hippotherapy. Another 10 elderly were assigned to the therapeutic ball group and they got with 30 minutes of therapeutic ball exercise. All procedures were repeated 5 times a week for the total of four weeks. To investigate the participants balancing abilities, the Time“ Up & Go”(TUG) and One Leg Stand Test(OLST) were evaluated. The results of study were significant differences between pre-test and post-test of TUG and OLST(p<.05), and there were no significant differences between hippotherapy and therapeutic ball exercise(p>.05). The conclusion showed that both the hippotherapy and the therapeutic ball exercises were effective on elderly balancing ability. Consequently, it would be better to practice therapeutic ball than hippotherapy for elderly exercise because the more economical and there is less restriction of space than the hippotherapy.

The purpose of the present study was to investigate the effects of familiar exercise and novel exercise on motor function after intracerebral hemorrhage (ICH) in rats. The rats were subjected to a unilateral striatal ICH via collagenase infusion. The rats were randomly divided into the following three groups: the CON (control group; rested one week post-ICH), the FE (familiar exercise group; familiar exercise was performed two weeks after one-week post-ICH period), and NE (novel exercise group; novel exercise was performed two weeks after one-week post-ICH period). We measured neurological behavior using a ladder rung walking test and a beam walking test; we measured the level of nerve growth factor (NGF) using immunohistochemistry and western blot analysis. We performed a one-way ANOVA test to analyze the scores obtained from the neurological behavior tests and the differences of NGF protein levels among the three groups. In the present study, the FE group and the NE group showed significant improvement during the neurological behavior tests and in their expression of NGF protein level, as compared to the CON group. Especially, NE group more increase than FE group in neurological behavior tests, the expression of NGF on motor cortex. In conclusion, these results suggest that, after ICH, familiar exercise and novel exercise enhance motor function and, novel exercise is more effective than familiar exercise.

This study aimed to determine the usefulness of classifying patients with neck pain on the basis of the results of passive scapular elevation test. We classified 21 patients with neck pain into positive (n=12) and negative (n=9) groups on the basis of passive scapular elevation test; the 2 groups then equally performed scapular stabilization exercise program for 30 min, 3 times a week, for 4 weeks. Visual analogue scale (VAS), neck disability index (NDI), and range of motion (ROM) were recorded both before and after the intervention for both groups. Paired t-test was used to determine that there were significant changes between before and after the intervention, and independent t-test was used for analyzing changes between two groups of dependent variables. After 4 weeks of training, we observed significant decrease in pain and disability (p<.05) and a significant increase in rotation, flexion, extension, and side-bending ROM (p<.05) in both groups. Further, between pre- and post-intervention evaluations, we observed a significant decrease in pain and disability and a significant increase in rotation and flexion ROM in the positive group than in the negative group (p<.05). These results indicate that passive scapular elevation test may be used to identify mechanical disorders of the cervicoscapular muscle in patients with neck pain. Therefore, we recommend the use of passive scapular elevation test to determine appropriate treatment intervention when treating patients with neck pain.

The lower trapezius muscle is an important stabilizer and primary mover of the scapula. The potential use of ultrasound imaging to evaluate scapular muscle function warrants investigation. The purpose of this study is to use ultrasound imaging for determining the effectiveness of 4 different isometric exercises for maximally activating the lower trapezius muscles in healthy subjects. Twenty-eight (14 men and 14 women) volunteers were recruited for this study. Thickness measurements of the lower trapezius muscles were recorded during 4 exercises: latissimus pulldown (LP), prone V-raise (PV), prone row (PR), and modified prone cobra (MP). Lower trapezius muscle thickness was measured 3 times by 2 investigators at a point 3 cm lateral to the lateral edge of the T8 spinous process. The order of 4 exercise execution was randomized for each participant. To identify statistical significance, one-way ANOVA with repeated measures was used with the significance level of .05. Intraclass correlation coefficient (ICC) for intra-reliability was .86~.98 and inter-rater reliability .83~.96 for the lower trapezius, respectively (p<.01). Thickness changes in the lower trapezius muscles between the relaxed and contracted states in men were as follows: LP (, 182%), MP (, 167%), PV (, 149%), and PR (, 133%). In women the values were as follows: LP (, 163%), MP (, 131%), PV (, 129%), and PR ( mm, 100%). Thickness of the lower trapezius muscles significantly differed between exercises in both the gender (p<.01). The LP was the most effective exercise for increasing the activation of the lower trapezius muscle in both the gender. We recommend performing the LP exercise for strengthening the lower trapezius muscles.

The aim of this study is to compare measurements of abdominal muscle thickness using ultrasonography imaging (USI) to those using a special transducer head device, during five different trunk stabilization exercises, ultimately to determine which exercise led to the greatest muscle thickness. Thirty eight healthy subjects participated in this cross-sectional study. The five types of trunk stabilization - i.e., a sit-up on the supine, an upper and lower extremity raise with quadruped on the prone, a leg raise in sitting on the ball, trunk rolling on the ball, and balance using sling on the prone position - were each performed with an abdominal draw. The thickness of the abdominal muscle - including the transverse abdominal (TrA), internal oblique (IO), and external oblique (EO) - was measured by USI with a special transducer head device, at rest and then at contraction in each position. Data were analyzed using one-way repeated ANOVA with the level of significance set at =.05. The results were as follows: 1) the TrA thickness was statistically significant (p<.05), whereas the IO and EO thicknesses were not (p>.05); 2) among the five types of trunk stabilization, TrA thickness significantly increased with the balance using a sling in the prone position, (p<.05), whereas no significant difference was noted for the four types of trunk stabilization (p>.05); 3) reliability data showed that there was a high degree of consistency among the measurements taken using the special transducer head device (ICC=.92). In conclusion, the balance using a sling in the prone position was more effective than any of the four other types of trunk stabilization in increasing TrA thickness in healthy subjects.

The purpose of this study effectiveness of core strengthening exercise programs on symmetric double limb support and balance ability for elderly. The subjects that 30 persons between the ages of 65~80 elderly participated were divided into two groups randomly for 8 weeks. Tetrax interactive balance system and Berg's balance scale were used to assess support and stability. Paired t-tests were used to evaluate the changes before and after intervention. The difference between the groups was compared using an independent t-test. The experimental group showed significantly increase weight support, stability, balance(p<.05). However, the control group not showed significantly increase weight support, stability, balance(p>.05). In a variation, experimental and control groups showed significantly increased rate of weight support, stability, balance(p<.05). Consequently, core strengthening exercise program should be considered as a therapeutic method for the elderly to improve the balance ability and effectiveness on falls.

This study was carried out to identify how a self-stretching exercise program affects pain for each body area, pain relief and job satisfaction for care workers. 20 of 40 care workers with musculoskeletal symptom were randomly selected and participated a self-stretching exercise program consisting of 15 motions. The intervention was done five times or more per weeks for 8 weeks and 1 session lasted within 15 minutes. 'Musculoskeletal symptom survey table' of the Korea Occupational Safety and Health Agency(KOSHA) and JDI(Job Descriptive Index) was used for pain on the musculoskeletal symptom and job satisfaction. Survey were done twice before and after the program. The result of this study showed that self-stretching exercise program group(SSPG) relieved from pain significantly in the shoulders(p<.01) and lumbar(p<.05), comparing to the non selfstretching exercise program group(NSPG). Although no significant difference on variations in the JDI appeared in SSPG, the significant reduction appeared from the colleague relationship and organization in NSPG(p<.05). SSPG showed the significant increase on variations in JDI from the job and organization comparing to NSPG. Especially, the improvement on satisfaction for the organization was shown(p<.05). Accordingly, the self-stretching exercise program for care workers can be said to positively affect the overall pain relief and increase on the JDI.

The purpose of this study was to assess the influence of patellar height on quadriceps muscles' electromyography (EMG) activity during a squat exercise in adults with patella baja. For the study, we recruited 15 volunteers who had patella baja on the right side. We measured the EMG activity of the right rectus femoris, vastus medialis oblique, and vastus lateralis muscles during squat exercises under two conditions, specifically with and without an infra-patellar strap. The infra-patellar strap was applied below the tested patella to elevate the patella to a normal height. A paired t-test was used to compare the effects of patella height on EMG activity of the quadriceps muscles. The EMG activity of the rectus femoris (RF), vastus medialis oblique (VMO), and vastus lateralis (VL) muscles were significantly decreased during the squat exercise with the infra-patellar strap compared to the same exercise without the infra-patellar strap (p<.05), while the VMO/VL ratio was not different significantly between two conditions (p>.05). The findings of this study suggest that an infra-patellar strap may benefit people with patellar baja, as changes in patellar height could improve the efficiency of the quadriceps muscles.

The aims of this study were to investigate the correlation between the electromyographic (EMG) activity of the abductor hallucis (AbdH) and the amount of pressure measured by a pinch gauge (PG), and to compare the EMG activity of AbdH and the pressure measured by the PG during short foot (SF) exercise in subjects with pes planus and in subjects with a neutral foot alignment. Fourteen subjects were recruited for this study (pes planus group=7; neutral foot alignment group=7). A surface EMG was used to collect AbdH activity, and a PG was positioned under the first metatarsophalangeal joint to measure the pressure produced by the first metatarsal head during the SF exercise. The AbdH activity and the pressure measured by the PG showed a positive good correlation (r=.80, p<.05). The EMG activity of the AbdH and the pressure measured by the PG were significantly lower for subjects with pes planus than for subjects with a neutral foot alignment (p<.05). Based on these findings, the PG can be recommended as an effective instrument for evaluating the performance of the AbdH. It may also be beneficial for monitoring how well the SF exercise is performed, and for providing visual feedback to patients with pes planus during SF exercise in a clinical setting.

The purpose of this study is to examine the effect of stabilization, resistance exercise, and combined exercise for lumbar on balance and walking ability of elderly. This study selected 22 subjects of over 65 years old elderly women who satisfy the study condition from A, B and C Senior Citizen's Center, in Daegu. The subjects were divided into groups; 7 for resistance exercise group, 8 for stabilization exercise group, and 7 for combined exercise group(resistance and stabilization exercise). The exercises were conducted for 60min a day, three times a week for 12 weeks. Balance and walking ability were checked before the exercise, 6 weeks later, and 12 weeks later. First, all lumbar muscle strengthening exercises were effective for static balance which changed according to exercising period. In dynamic balance, the resistance exercise group showed significant improvement in sit to stand. Stabilization exercise group showed significant improvement in all factors. The combined exercise group showed significant improvement in sit to stand and timed up and go. There was no difference between the exercise types. Second, the resistance exercise group showed significant change in Cadence which changed according to exercising period. The combined exercise group showed significant improvement in all factors. Between the exercise types, combined exercise was a bit more effective than resistance exercise. According to the result of 12 weeks of lumbar muscle exercise, combined exercise is considered to be the most effective exercise to prevent fall as it helps balance and walking ability slightly more than other exercises. Therefore, this study can understand the risk factors for fall accidents that frequently occur among elderly and adopt the combined exercise to prevent fall which in turn will prevent secondary problems occur from fall accidents and improve quality of life of elderly.

The purpose of this study is to examine the activity ratios of global trunk muscles and local trunk muscles in relation to adjustments in the level of task difficulty while performing stability exercises in easily applied bridging lumbar stabilization exercise. Twenty healthy subjects performed bridging lumbar stabilization exercise while the level of task difficulty was plate was used in the same posture for all the exercises. EMG was used to examine the activity ratios of the global muscles and multifidus in relation to the level of task difficulty. Moreover, the activity ratios of the multifidus muscle, the erector spinae and the gluteus maximus muscle were measured. A one-way ANOVA with repeated measures was used, and a Bonferroni correction was conducted (=.05). When the bridging lumbar stabilization exercise were performed at different difficulty levels, the activity of the multifidus muscle, which is a local muscle, was high in all three exercises. Also, compared to low intensity and intermediate intensity exercises, high intensity exercises showed more significant differences (=.05). Among all the muscles, the multifidus showed the highest activity at intermediate intensity. Based on these results, we suggest that in the case of bridging lumbar stabilization exercise, low intensity or intermediate intensity exercises are more suitable and efficient for local muscle stabilization.

The purpose of this study was to evaluate the effects of bridging stabilization exercise on balance ability and gait performance in elderly women. The subjects of this study were thirty-one elderly women over 65 years old in HongSung-Gun Senior Citizen Welfare Hall. The subjects were randomly assigned into one of three groups (trunk stabilization exercise on the mat, whole body vibration, and Swiss ball) and participated in each exercise program three times a week for 4 weeks. Each exercise began in the bridging position. The dynamic balance and gait were measured by limit of stability area using force plate, Berg Balance Scale (BBS), and Timed Up and Go Test (TUG). The results were as follows: 1) The limit of stability in three groups increased significantly in anterior-posterior and medial-lateral lean after 4-weeks intervention (p<.05). 2) There were no significant differences in the limit of stability among three groups after 4-weeks intervention (p>.05). 3) The BBS and TUG in three groups increased significantly after 4-weeks intervention (p<.05). 4) There were significant differences among three groups in BBS. Post-hoc test showed that Swiss ball exercise group was significantly higher than the mat and whole body vibration groups. 5) There were no significant differences TUG among three groups after 4-weeks intervention (p>.05). In conclusion, this study suggested that 4 weeks of the bridging stabilization exercises were effective on balance and gait in all three groups. Particularly Swiss ball exercise group showed higher improvement than two other exercise groups (mat, whole body vibration group).
