Objective: The purpose of this study was to investigate the effects rhythmic and non-rhythmic aerobic exercises on depression and balance of healthy elderly people. Design: Randomized controled trial. Methods: Nineteen older subjects were randomly divided into 2 groups for rhythmic and non-rhythmic aerobic exercises. Both aerobic exercises consisted of functional movements such as turning in opposite directions, and running in place, the exercise consisted of movements that could activate balance. The rhythmic training group initially used music with 8 beats, and then later progressed to 16 beats. Additionally, we adjusted the pace of the music using songs from 125 beats per minute (bpm) to 160 bpm. Both groups were exercised for 50 minutes a day, twice a week, for a total of 8 weeks. We measured the condition of the patients before the intervention, and after 8 weeks of intervention. The Beck depression inventory (BDI) was used to measure the degree of depression. The Berg balance scale (BBS) was used to measure static and dynamic balance ability. We measured the subject's subjective balance confidence using the fall efficacy scale (FES). Results: Both groups showed significant improvement in BDI, BBS, and FES (p<0.05). The rhythmic aerobic exercise group showed a significant improvement only in the BBS change values compared to the non-rhythmic group (p<0.05). Conclusions: According to this study, both rhythmic and non-rhythmic aerobic exercises resulted in significant improvement in the degree of depression and balance ability of the elderly. The rhythmic aerobic exercise was more effective for dynamic balance ability.

Conditions related to body composition and aging, such as osteopenic obesity, sarcopenia/ sarcopenic obesity, and the newly termed osteosarcopenic obesity(triad of bone, muscle and adipose tissue impairment), are beginning to gain recognition. Currently, it has begun to attract the attention of scholars from all over the world, however, for this disease, it still needs a more clear understanding and perception. Therefore, this article considered the osteoporosis, muscle depression, and obesity, these diseases as a gate to study the relationship among muscle, bone, and fat. In addition, in the aging process, the formation of IGF-cortisol, testosterone, and estrogen is sensitive. These hormones can not only absorb muscle protein metabolism, but also affect alienation. The decrease in IGF-cortisol in the elderly resulted in increased visceral fat, decreased muscle mass and bone mineral density, and then affected decreased skeletal muscle atrophy and decreased quality. The reduction of skeletal muscle quality and strength and increase body fat affected the adipose tissue to produce inflammatory cytokines, thereby reduced skeletal muscle, promoted cardiovascular disease, metabolic syndrome and insulin resistance in chronic diseases. Almost all chronic inflammatory diseases were associated with bone, muscle and fat. These mechanisms were complex and interrelated. Inflammation reduces bone formation, increases fat and reduces muscle mass. And thus not only had a significant impact on the motor system, but also made the incidence increase of fracture, osteoporosis, fragile syndrome, fall, osteomalacia and other bone disease. This article aimed to start from the interaction between the muscles and bones of the elderly, extended to obesity, muscle deficiency, osteoporosis and other diseases, finally, from a nutritional point of view, to discuss how to treat osteoporosis obesity.

The purpose of this study is to offer basic data for the fall prevention by analyzing the kinematic difference between the lower limb joints and the lower extremities in elderly people's walking given the lower-limb resistance exercises. For this, three-dimensional image analysis was carried out by selecting 7 elderly women from over 70s to under 80 years old. To obtain the three-dimensional location coordinates in the lower limb joints and the lower extremities, it shot with 100Hz/s by using MCU(Qualisys, Sweden) camera. The shot image gained raw data on the location coordinates by using QTM(Qualisys, Sweden). As a result of calculating three-dimensional angle by using program of Matlab 6.5, the following conclusions were obtained. Flexion and extension in the thigh and the lower-leg extremities were indicated to be big in motion of flexion after exercising at E5. Foot segment indicated statistical difference while showing eversion at E4. Knee joints showed flexion at E4 after exercising. Ankle joints showed statistical difference while indicating motion in inversion at E3 and in eversion at E4(p<.05).

The purpose of this study was to compare the effects of the intensive ankle joint strategy training on the muscular strength and balancing ability in the elderly women. The subject of this study were 30 elderly women aged from 65 to 80 and randomly assigned to three groups. For 6 weeks, two experimental groups took the training an hour every 3 days of a week. The results that measured the dynamometer, FRT, and SEBT after implementing general lower limbs exercise and the intensive ankle joint strategy training for 6 weeks showed that the changes in the control and experimental group I were not statistically significant while the changes in the experimental group II were statistically significant (p<.05). For the prevention of the elderlies from fall and the treatment approaches, it is deemed to be necessary additional studies on the diverse variables through the intensive training of the ankle strategy.

An ECG analysis with activity monitoring for the home care of elderly persons or patients, using wireless sensors technology was design and implemented. The changes in heart rate occur before, during, or following behavior such as posture changes, walking and running. Therefore, it is often very important to record heart rate along with posture and behavior, for continuously monitoring a patient's cardiovascular regulatory system during their daily life activity. The ECG and accelerometer data are continuously recorded with a built-in automatic alarm detection system, for giving early alarm signals even if the patient is unconscious or unaware of cardiac arrhythmias. The hardware allows data to be transmitted wirelessly from on-body sensors to a base station attached to server PC using IEEE802.15.4. If any abnormality un at server then the alarm condition sends to the doctor' PDA (Personal Digital Assistant).

This study has a purpose to devise an education program in relation to Gerontology and geriatrics applicable to Korean nurses through literature review and analysis of education programs utilized by the Geriatric Education Centers (GECs) of USA. Educational contents on gerontology and geriatrics are very diverse in precedent literatures. The education programs of GECs for health care personnel are equally very diverse. Among educational contents, subjects considered important are age-related changes, health problems of the aged, pharmacology, death, fall and osteoporosis, delirium, dementia, depression, urinary incontinence, communication with elderly. Methods used in education program are mainly seminar, workshop and lecture through internet. In addition, case study, small-group discussion and conference are also adopted. The program proposed in this study for nurses in relation to gerontology and geriatrics consists of 32 hours' education; 6 hours for age-related changes, 10 hours for health problems of the elderly, 14 hours for health problems in old age and 2 hours of communication technique. Educational method proposed is to utilize lecture through internet, direct education, workshop, practical exercise, case study and role play in parallel. This study proposed an education program on the basis of precedent literature and the program of GECs. Therefore, it is desirable to develop in the future more practical education program applicable to and required in practicing fields. Of course, this development needs to be based on nurses' educational needs by field in relation to gerontology and geriatrics.

This study is aimed to evaluate the effects of community-based prehabilitation program developed to prevent functional decline in the frail elderly and to provide a basis to practically operate this program in the public health care service. From March to August 2009, 110 frail elderly people were recruited among the registered participants of the home visit program in Korea to perform a prospective randomized community trial. We randomly assigned these people into two groups. One group (n=50) participated in the visiting prehabilitation program for 3 months focusing on improving their muscle strength of upper and lower limbs, walking ability, and balancing. The other group (n=60) underwent our visiting fall prevention program for control. To assess the effectiveness of prehabilitation program, physical functioning (PF) and short physical performance battery (SPPB) were measured for the primary outcomes and also some other indicators: exercise performance, nutritional status, emotional functioning, experience of admission, and events of fall. As a result, significant improvements of geriatric functional status were noticed among the participants. After 3 months, PF increased by 1.3 ± 3.8 points in prehabilitation group and decreased by 1.1 ± 5.4 points in controls (p=.020). SPPB improved by 2.4 ± 2.0 points in prehabilitation group and increased only 0.3 ± 1.5 points in controls (p<.001). Significant effects were also shown in their exercise performance tests and emotional status, the number of multiple falls, and the experience of functional decline after the fall (p .002-.038). Visiting prehabilitation program is safe and effective program for frail older adults. Thus, it is strongly recommended to universally adopt this program to prevent functional decline in the frail elderly.

The purpose of this study was to provide basic data for the development of fall prevention programs for the elderly and for improvement of quality of life based on history of falls, chronic diseases, location, fear of falling, daily living activities, and quality of life. This study was conducted from 15th August to 17th September of 2016 on 185 elderly subjects above the age of 65 living in four centers of J city and four centers of J rural. The results of this study are as follows: There were no statistically significant differences in daily living activities, fear of falls, and quality of life regarding falls in the past. There were statistically significant differences in fear of falling and quality of life regarding chronic diseases. There were statistically significant differences in daily living activities and quality of life regarding residence. This study confirms that there were relations among daily living activities, fear of falling, and quality of life, and there was a negative correlation between fear of falling and accomplishment of daily living activities(r=-.386, p<.000). There was also a positive correlation between accomplishment of daily living activities and quality of life(r=.513, p<.000). Therefore, avoiding outings on slippery roads and creating safe environments for the elderly are important to reduce fear of falling. Additionally, a system should be developed for the elderly to acquire necessary information for daily life.
