Portable ladders are normally used both as an access tool for ascending and descending and as a platform for high place work. Though convenient, such usages make the portable ladders vulnerable to fall accidents. For this reason, many safety systems such as regulations and certifications are implemented to prevent fall accidents of portable ladders. However, nevertheless of those safety systems in Korea, annual death tolls of ladder fall accidents has remained high, and which suggests modification and improvement of the portable ladder related safety systems in Korea. The aim of this study is to propose directions for improving safety systems to effectively prevent fall accidents of portable ladders. To this end, comparative analysis on safety systems implemented in Korea and other countries including Japan, USA and UK are conducted to investigate the problems of Korean safety systems. Based on the analysis, limitations of Korean safety systems to prevent ladder fall accidents are discussed and tasks to overcome the limitations are proposed. Once implemented, the proposed tasks would contribute to prevent ladder fall accidents effectively.

Purpose: This study was done to propose and test a predictive model that would explain and predict fall prevention behaviors in postmenopausal women. The health belief model was the theoretical basis to aid development of a nursing intervention fall prevention program. Methods: Data for 421 postmenopausal women were selected from an original data set using a survey design. The structural equation model was tested for 3 constructs: modifying factors, expectation factors, and threat factors. Expectation factors were measured as relative perceived benefit (perceived benefit minus perceived barrier), self-efficacy, and health motivation; threat factors, as perceived susceptibility (fear of falling) and perceived severity (avoiding activity for fear of falling); and modifying factors: level of education and knowledge about fall prevention. Data were analyzed using SPSS Windows and AMOS program. Results: Mean age was 55.7 years (range 45-64), and 19.7% had experienced a fall within the past year. Fall prevention behaviors were explained by expectation and threat factors indicating significant direct effects. Mediating effect of health beliefs was significant in the relationship between modifying factors and fall prevention behaviors. The proposed model explained 33% of the variance. Conclusion: Results indicate that fall prevention education should include knowledge, expectation, and threat factors based on health belief model.

In modern society, the elderly over 65 years old are increasing due to development of medical technology and improvement of their standard of living. Severe fall of the elderly can lead to death threats. To solve this problem, several algorithms and hardware systems for fall detection have been studied and developed. In this paper, a fall detection system using 3-axial acceleration sensor is presented. In the fall detection system, several types of fall-feature parameters are calculated and then the fall is determined by using them. Using this system, best sensitivity and specificity are 98.3% and 94.7%, respectively.

Background: This study analysed the effect of the fall prevention education activities on balance, fall efficacy, activities of daily living (ADL) of sub-acute stroke patients. Design: Randomized controlled trial. Methods: The subjects of the study were 24 subacute patients, who have onset period of less than 6 months. They are randomly allocated in the conventional therapy group (n=12) and fall prevention education group (n=12) and observed with frequency for 5 times a week for four weeks. Measuring took place before and after the experiment leading to following results of the Fall efficacy scale (FES), Berg balance scale (BBS) and Functional Independence Measure (FIM). Results: FES, BBS and FIM score was significantly greater in the post-test than in the pre-test in both groups (p<0.01). Independent t-test confirmed that the fall prevention education group showed much greater improvement change in the FES, BBS and FIM score than conventional therapy group (p<0.05). Conclusion: The present study demonstrated the importance of clinical contribution of the fall prevention education in the individuals with subacute stroke patients to the balance, fall efficacy and ADL following the stroke rehabilitation.

A newly developed fall detection algorithm using the HMM (Hidden Markov Model) extracted from the video is introduced. To distinguish between the fall from personal difference fall pattern or the normal activities of daily living (ADL), HMM machine learning algorithm is used. For getting fall feature vector of video, the motion vector from the optical flow is applied to the PCA (Principal Component Analysis). The combination of the angle, ratio of long-short axis, velocity from results of PCA make the new fall feature parameters. These parameters were applied to the HMM and the results were compared and analyzed. Among the newly proposed various kinds of fall parameters, the angle of movement showed the best results. The results show that this parameter can distinguish various types of fall from ADLs with 91.5% sensitivity and 88.01% specificity.

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.
