“…Previous studies utilizing the mental chronometry method have reported that the duration or distance of an imagined movement corresponds poorly to the duration or distance of the actual movement in elderly individuals3, 7, 8 ) . In the present study, we utilized a different method to evaluate judgment error in elderly individuals.…”

[Purpose] “Judgment error,” defined as a difference between the actual and the imagined performance, is often observed in elderly persons. The aims of this study were to assess subjective judgment errors in elderly persons, and to evaluate the relationship between physical function and judgment error in walking speed. [Subjects and Methods] A total of 106 community-dwelling elderly individuals participated. Subjects observed video footage of a model walking an obstacle course, and were asked to subjectively compare the model’s gait speed with their own gait speed. When the subjective comparison differed from the actual difference, it was considered as a judgment error. Physical function was compared between those with and without judgment error. [Results] Significant interaction effects between the actual performance and subjective perception were found for the walking time on the obstacle course and the Activities-specific Balance Confidence Scale score (utilized as an index of self-confidence in own balance ability and a fear of falling). [Conclusion] The results demonstrate that some elderly persons tend to overestimate their balance and ambulation function compared to another person, even though they had low physical function and low self-confidence in terms of balance. These elderly individuals might have a high risk of accidents.

“…As described above, overestimation of physical ability [26] is considered a potential fall risk. Therefore, we expected that the frequency of fall experiences in patients who overestimated their ability and had less anxiety in hospital would decrease after watching the animation movie.…”

“…In these reports, we found that patients overestimated their physical ability. Reportedly, overestimation of physical ability is a possible fall risk [26], and inadequate self-estimation resulted from unawareness of decreased physical status and fall risks [27]. Then, we asked patients how they estimated their own physical ability normally and in hospital.…”

Background: In this study, we developed an animated movie as a novel educational tool for fall prevention, and intended for patients and caregivers. We evaluated this new animation, comparing its effectiveness both before and after intervention, and have discussed its potential in the context of inpatient fall prevention. Methods: While including previously implemented multidisciplinary fall prevention measures, we started to introduce the use of animation in August 2013. Pre-and post-intervention questionnaire surveys were conducted for patients and nurses in June and August 2013, respectively, for 2 weeks. Results: We obtained 304 and 269 paired data in the pre-and post-intervention survey periods. On examining the difference between nurses' instructions and patients' understanding, in the pre-intervention period, only 70.0 % of patients instructed to call the nurses at any time and 33.3 % of those instructed to call at the time of need, correctly understood the instructions. The frequency of patients' falls significantly decreased from 15.6 to 8.6 % (p <0.05) between the pre-and post-intervention survey periods, respectively. In 65-year-old patients, the ratio of frequency significantly decreased from 19.0 to 7.6 % (p <0.01); however, it did not change in patients aged <65 years. Conclusions: Our study indicated that animation could be an effective educational tool for inpatient fall prevention, even in older patients. In order to develop a multimedia tool with optimal educational impact, several aspects should be explored, including the addition of previous multidisciplinary approaches, increased variety of story and character design, improved hospital culture for better staff compliance and enhanced effectiveness, and interactive digital media content for an effective teaching feedback loop.

“…Several researchers have reported on the relationship between aging and judgment errors about physical ability and on the relationship between falls and judgment errors9,10,11, 15,16,17,18,19 ) . In these studies, several tasks were utilized to evaluate judgment errors of physical ability in the elderly.…”

“…The assessments can be roughly divided into two types: spatially predictive tasks and temporally predictive tasks17 ) . The Functional Reach Test (FR) or other reaching tasks, step-over test, and maximum one stride length test are examples of spatially predictive tasks9, 10, 12, 17,18,19,20 ) . The Timed up and Go test (TUG), maximum gait speed, 20 step walking time, and single-leg standing are examples of temporally predictive tasks15,16,17 ) .…”

[Purpose] The present study compared assessments utilized to evaluate judgment errors in the elderly. [Subjects and Methods] A total of 94 community-dwelling elderly participants in an examination of physical fitness for health promotion and health guidance in a rural area in Japan were included. Spatially and temporally predictive tasks were used to evaluate judgment errors. Distances measured on the Functional Reach and upward reaching tests were used to assess spatial prediction, and times measured on the Timed Up and Go test and Standardized Walking Obstacle Course were used to assess temporal prediction. Differences between the self-predicted values and actual results were deemed judgment errors. [Results] Significant differences were observed between self-predicted abilities and the patients’ performances. Participants underestimated their abilities in spatially predictive tasks and overestimated them in temporally predictive tasks. On comparing the four tasks, there were significant differences in judgment error ratios between them. Statistical analysis indicated a significant difference in the judgment error ratio for the Standardized Walking Obstacle Course correlated with a history of falls. [Conclusion] Judgment errors were identified using both spatially and temporally predictive tasks. A temporally predictive task like the Standardized Walking Obstacle Course might better evaluate judgment errors in the elderly.
