Accidents are the fourth-leading causal factor of death among the elderly, and fall is a major type of accident (53.17%). Many cases of falls in the elderly result in delayed discovery and loss of quality of life. As the number of the elderly grows, falls will be a more important health problem. Most previous research on falls investigated prevalence. mortality, and the related factors. There are many studies proving the effect of rhythmic movements. But few researches considered linking risk factors of fall with rhythmic movements. Purpose: We want to show the changes after performing rhythmic movement program, in risk factors of falls and mobility such as flexibility, balance, muscle power and persistency in the elderly, in order to provide basic information needed for the development of fall injury prevention program for the elderly. Method: The design of this study is quasi-experimental, the equivalent control group, pretest-posttest. The subjects consist of 124 people who lived in Do-Bong-Qu. Seoul, agreed to participate in this study, and were able to follow this rhythmic movement program. About 93 % of them are from 65 to 84 years (Mean${\pm}$sd: $73.7{\pm}5.7$): 64% are female. The rhythmic movement program was designed. and performed by two community health nurses working in the Do-Bong-Gu Public Health Center, regularly twice a week from May, 4 to December, 17. in 10 senior citizens' community centers. Risk factors of fall were measured with RAFS- II (Risk Assessment for Falls Scale II) by asking about each item: mobility was measured by observing their specific movements asked by investigators. Results: 1. After performing the program during 7 months, risk factors score of falls were decreased significantly (paired-t = 4.77. p<0.01). 2. After performing the program during 7 months, flexibility (paired-t = 2.26. p=0.03) and mobility were improved (paired-t = 4.98. p<0.01). but muscle power and persistency did not change (paired-t = 0.33. p=0.74). Overall, mobility affecting the occurrence of falls was improved significantly (paired-t = 5.15. p<0.01). Conclusions: A regular rhythmic movement program can be helpful in preventing falls in the elderly. Further. we can develop a fall injury prevention program using rhythmic movement.

The purpose of this study was to compare the balance and gait between fallers and non-fallers in elderly. A brief questionnaire was used to obtain the fall history. Twenty-seven women subjects were evaluated in this study. Eleven subjects and a mean age of 84.5 years (SD=4.6) were designated as the faller group. Sixteen subjects and a mean age of 80.3 years (SD=5.3) were designated as the non-faller group. The fall-related factors (mental status, balance, range of motion and muscle strength of lower extremity, sensation of foot, and cadence, walking velocity, stride length) were compared between faller group and non-faller group and measured. The results showed that faller group had significantly less range of motion of the hip flexion and knee extension, and strength of the knee extensor and ankle dorsiflexor and plantar flexor than non-faller group. The scores of the Functional reach test and One leg standing were significantly less in faller group than in non-faller group. Faller group showed less walking velocity and stride length compared to non-faller group. However, there was no significant difference in cadence during comfortable waking and fast walking between two groups. There were no significant differences in pressure, position sensory between two groups. These results suggest that exercise for improving the flexibility, muscle strength of the lower extremity and balance may be useful strategies to prevent fall in elderly. Further studies are needed to identify which specific factors are related to fall in the elderly population.

This study was a quasi-experimental study of non-equivalent control group pretest and posttest design. The purpose of this study was to determine the effect of Tai Chi exercise program on physical functions, psychological functions, and fall among the fall-prone elderly. The data were collected from September 19, 2001 to January 31, 2002. The study, conducted at two facilities located in Kwang-ju, was targeted to the ambulatory aged 60 years or older who had at least one of the key fall risk factors. Experimental group participated in Tai Chi exercise for 40 minutes per one time and three times a week for 12weeks at an auditorium. Fifty nine fall-prone elderly were assigned to 12-week Tai Chi exercise program (n=29) and control group (n=30). They underwent tests of lower muscle strength, time for chair stand, balance, flexibility, depression, falls efficacy, fear of falling, and numbers of fall at the baseline and at the 12th week. Numbers of fall and fall injuries were monitored for 16 weeks(12-weeks intervention plus 4-week follow-up periods) using fall calendar. Each participant was given a calendar to record the numbers of fall per day for a month. The calendars were collected at the last week of each month. 1. Tai Chi exercisers showed significant improvement in the strength of knee flexors, and ankle dorsiflexors and plantarflexors compared to the control group. The experimental group had improvement in the strength of knee extensors while the control group did not, with no statistical significance. 2. Tai Chi exercisers reported positive change in the average time of chair stand as compared to the control group. 3. Tai Chi exercisers had significant improvement in flexibility as compared to the control group. 4. There was no significant difference in the depression between the two groups, even though the Tai Chi exercisers maintained depression score in the same level while the others were increased. 5. Tai Chi exercisers showed significant improvements in the falls efficacy as compared to the control group. The falls efficacy was significantly improved among the experimental group while the opposite was identified among the control group. 6. The experimental group reported the significant reduction of the fear of fall, whereas control group reported the opposite. 7. Of the 59 subjects for 16weeks(12weeks intervention period and 4weeks follow up), 9 (31.0%) of the 29 in exercise group and 15 (50%) of the 30 in the control group fell (relative risk=0.62. 95% CI 0.32-1.19), even with no statistical difference. The results suggest that the Tai Chi exercise program can improve the strength of knee flexors, ankle dorsiflexors and plantarflexors, chair stand. flexibility, falls efficacy, and fear of falling for the fall-prone elderly.

Purpose: The aim of this study was to examine the effects of sling exercise on fall risk score, ankle dorsiflexion and balance in community-dwelling elderly women. Method: A 6-week prospective study was conducted to examine the effects of sling exercise. Participants were required to attend their assigned exercise classes three times a week for 6 weeks. Result: After the 6 week study period, PPA fall-risk scores were reduced by 0.90 for the exercise group, which was a significant change (p<.001). Dorsiflexion strength increased significantly (p<.01) by 1.56 kg after the sling exercise. There was a 2.0 cm-increase (p<.05) in FRT and 0.38 second-improvement (p<.01) in TUGT. A 7.88 second-increase in One-leg standing with Eyes Open and a 3.12 second-increase in One-leg standing with Eyes Closed were reported during the 6-week intervention period. Conclusion: The 6-week sling exercise reduced falls risk score significantly (p<=.001) in community-dwelling elderly women by improving fall risk related factors such as reaction time, balance and strength.

Purpose: The study aimed to examine the effects of Tai Chi fall prevention program on risk factors for fall, fear of falling, and quality of life among elderly women living in the community. Methods: A quasi-experimental pretest-posttest design with non-equivalent control group was used. Sixty participants were recruited from 4 senior citizen centers in a city. The 1-hour Tai Chi fall prevention program was provided three times a week for 6 months to the experimental group. Risk factors for fall including fracture risk and bone mineral density, fear of falling, and quality of life were measured at the baseline and at 6 months. Results: Participants were 75 years old in average. At the completion of 6 month program, the experimental group showed lower fracture risks, less fear of falling, and higher scores in several domains of quality of life than the control group, after controlling for the pretest scores, fall experience, and regular exercise habit. Conclusion: The Tai Chi fall prevention program was safely applied to elderly women with improvement in fracture risk, fear of falling, and several domains of quality of life. Future study is necessary to confirm the longer effect of the Tai Chi program for the prevention of fall episodes.

독거노인이 증가하면서 낙상 사고 빈도도 높아지고 있다. 낙상은 노인들의 건강을 위협할 뿐만 아니라, 독립적인 생활을 위협할 수 있다. 이 문제를 해결하기 위해서는 독거노인의 위급한 상태를 인식하고 대응할 수 있는 실시간 기술이 필요하다. 따라서 본 논문은 독거노인을 위해 긴급 상황 중 하나인 낙상을 실시간으로 확인할 수 있는 YOLO-KCF를 기반 개선된 낙상 감지 알고리즘을 제안한다. YOLO는 물체의 검출뿐 아니라 서 있는 행동과 쓰러지는 행동 유행을 감지할 수 있다. 따라서 본 논문은 서 있는 행동 유형과 쓰러지는 행동 유형간의 경계 박스의 형태 변화를 이용하여 낙하를 검출할 수 있으며, KCF의 단점을 개선할 수 있다.

Purpose: The purpose of this study was to understand the experience and meaning of falls among care workers caring for the elderly. Methods: The participants comprised 10 care workers in Seoul and Gyeonggi Province, South Korea. The data collection period was from September to November 2020, and the data were obtained through individual in-depth interviews. The collected data were analyzed using the content analysis method of qualitative research. The main interview questions were as follows: First, in the event of a fall, "can you tell us about your experience and how you dealt with the fall?; second, "can you tell us about your role and the role of family members or the center that manages falls that occur outside of nursing visits.", third, "can you tell us about the difficulties in managing falls based on your experience?", and fourth, "how are falls that occur during nursing visits managed?" Results: As a result of analyzing the experiences of nursing care workers of falls while caring for elders in their homes, five main themes were derived. These were understanding the characteristics of the elderly at home, understanding possible emergency situations, providing caring services, minimizing physical harm, and delivering clear information. Conclusion: A significant finding of this study was that care workers who visit and provide care to elders at home confirmed the need for standard guidelines on appropriate responses in the event of a fall at home and the importance of managing emergencies arising from falls among elders at home. These results highlight the need for the development of emergency response education programs, such as programs on fall care among nurses and care workers who provide care to the elderly, and for enhanced understanding of the fall risk of elders who live at home.
