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.

The purpose of this study is to investigate the effect of gardening programs using therapeutic gardens on the fall efficacy of the elderly. This study was applied to 31 elderly facility users from April to August 2019 at a nursing home P located in Gyeonggi-do. Among the 31 participants who participated in the program, 16 subjects in the experimental group and 15 subjects in the control group were randomly selected. As for the experimental group program, a fall program consisting of fall education and strength training four times a week and a horticultural occupational program were implemented once a week in a healing garden for a total of 15 weeks. The control group performed fall program for 30 minutes 5 times a week for a total of 15 weeks. The fall efficacy of the tested group increased by 5.50 points from 29points before the program to 34.50points after the program, and statistically significant results were obtained (p=0.000). The control group who only progressed the fall program increased 3.63 points from 28.87points before the trial to 32.50points after the trial, and statistically significant results were obtained (p=0.000). From this result, it can be confirmed that the horticultural program using the treatment garden has the potential as a program related to falls. In the future, various studies are needed so that gardening programs using gardens can be applied to prevent falls of the elderly.
