본 논문에서는 낙상과 비낙상 구별을 위한 분류 모델을 제안한다. 일상생활과 낙상을 구분해 내는 것은 낙상이 발생하기 이전에 감지하고 사고를 예방할 수 있다. 낙상은 일상생활 중 일어나기 쉬우며, 노인들에게는 골절 및 기관 파열 등과 같은 심각한 부상을 초래할 수 있기 때문에 낙상 방지를 위한 낙상과 비낙상 행동의 구분은 중요한 문제이다. 따라서 실시간으로 수집되는 다양한 활동에서의 센서 데이터를 활용하여 낙상과 비낙상의 행동을 구분하였다.

Falling is one of the problems that threatens the health of elderly patients. This study was conducted once a week for 12 weeks, from 15th of April to 13th of June in 2016, and included 118 subjects above the age of 65 in 6 centers of J city. We evaluated the effectiveness of the fall prevention exercise program (FPEP) and analyzed its effects by making a comparison between before and after the exercise that pertains to activities of daily living, fear of falling, and quality of life. Moreover, this study confirms that there is a relationship between these three factors. The results of this study are as follows: There were statistically significant differences of activities of daily living (F=-4.75, p<..001), fear of falling (F=10.22, p<..001) and quality of life (F=-11.58, p<..001) between post-test improvements and pre-test conditions. In addition, this study confirms that there is a relationship between activities of daily living, fear of falling, and quality of life (r=.551, p<..001, r=-.477, p<..001, r=-.584, p<..001). Accordingly, we have identified that FPEP is very effective for improving activities of daily living, fear of falling, and quality of life for senior citizens.

Purpose: This study aimed to investigate the influence of fall risk, fear of falling, and social support on older inpatients' fall prevention behaviors. Methods: The participants were 105 older inpatients. Data were analyzed using descriptive statistics, independent t-test, One-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis using the SPSS program. Results: The mean fall risk, fear of falling, social support, and all prevention behaviors were 58.05±28.27, 2.47±0.67, 3.58±0.63, and 2.93±0.48, respectively. There were significant differences in fall prevention behaviors by sex, and fall related to education experience. Fall prevention behaviors were associated with fall risk, and fear of falling. The factors influencing the fall prevention behaviors of the older inpatients were sex, fall related to educational experience, fall risk, and fear of falling. It was found that 21% could explain fall prevention behaviors. Conclusion: The results indicate a need to develop a fall prevention education program, including intervention, to reduce the fear of falling among older inpatients.

This study was understood the risk mechanism of falls in the elderly and reviewed previous research data to see if the principle of Pilates rehabilitation exercise could have a positive effect on balance ability and postural stabilization in the elderly, and the purpose of this study is to present literature-based data on the fall prevention effect of rehabilitation Pilates exercise. First, the rehabilitation Pilates exercise makes it available for strengthening the center of the body to stabilize the spine and pelvis and stimulates the nerve root, thereby having an effect on the balance and the joint stabilization. Second, a proprioceptive sensory impairment and a musculoskeletal degenerative disease due to aging increase the loss of balance ability and the instability in posture maintenance, thereby coming to raise the risk of a fall damage caused by the difficulty in performing motor functions and by the gait disturbance. Third, the rehabilitation Pilates exercise leads to improving the core muscle strength in older adults, resulting in being capable of expecting the betterment in the balance and the reaction time motor function. And there is a positive impact on the improvement in body imbalance and on the stability in movement involved in the fall prevention, resulting in being able to suggest the possibility of likely contributing to a reduction in a fall risk rate. In conclusion, the rehabilitation Pilates as the elderly exercise program showed effects on the improvement in the body's muscular strength, on the upgrade in a sense of balance, and on the stabilization of core. Thus, it was considered to diminish the risk factors for a fall damage caused by musculoskeletal degeneration and to be capable of preventing a serious disorder of activity due to a chronic senile disease.

Understanding sciences behind fall-related hip fractures in older adults is important to develop effective interventions for prevention. The aim of this review is to provide biomechanical understanding and prevention strategies of falls and related hip fractures in older adults, in order to guide future research directions from biomechanical perspectives. While most hip fractures are due to a fall, a few of falls are injurious causing hip fractures, and most falls are non-injurious. Fall mechanics are important in determining injurious versus non-injurious falls. Many different biomechanical factors contribute to the risk of hip fracture, and effects of each individual factors are known well. However, combining effects, and correlation and causation among the factors are poorly understood. While fall prevention interventions include exercise, vision correction, vitamin D intake and environment modification, injury prevention strategies include use of hip protectors, compliant flooring and safe landing strategies, vitamin D intake and exercise. While fall risk assessments have well been established, limited efforts have been made for injury risk assessments. Better understanding is necessary on the correlation and causation among factors affecting the risk of falls and related hip fractures in older adults. Development of the hip fracture risk assessment technique is required to establish more efficient intervention models for fall-related hip fractures in older adults.
