Purpose: Japan is now the world's first ‘super-ageing’ society. We analysed the effect of occupational therapy (OT) sessions in addressing issues related to the elderly population, in comparison with other services.
Methods: We studied 136 elderly patients receiving at-home care. Seventy-four patients received weekly OT and 62 did not. We assessed quality of life (QOL) and its trajectory over 1 year using the Philadelphia Geriatric Center Morale Scale (PGC) to quantify changes in QOL and the Function Independence Measure (FIM) to measure changes in activities of daily living.
Results: Patient progress fell within five different trajectories, which was influenced by psychosocial factors. OT correlated with significantly greater improvement in PGC and FIM scores than other home care services.
Conclusion: There is a significant benefit associated with OT and is expected to become increasingly more important in the growing elderly population. Tailoring of OT will be required to benefit those trajectory groups that showed unsatisfactory outcomes.
Several studies have been implemented on home-visit occupational therapy based on activities or occupations for clients with dementia and their caregivers, but all have been conducted abroad; none have taken place in Japan. Therefore, we performed a pilot study of the effectiveness of an occupation-based home-visit program for clients with dementia and their caregivers using single cohort design. The results of our analysis of participants' (n = 9) data indicated that the home-visit program could improve the behavioral and psychological symptoms of dementia, particularly apathy, among clients with dementia, as well as caregivers' needs or what caregivers expected of clients. Additionally, the program tended to decrease caregivers' care burden. The implications of the study are discussed in light of further research on this program.
The hypothesis in this study was tested by conducting EMG experiments comparing the variability in muscle activity during repetitive reaching movements in hemiplegic patients and healthy subjects. The present study investigated the characteristics of reaching movements in hemiplegic patients using the variability in average electromyogram (EMG) value. We studied 21 right-handed stroke patients with left-sided hemiparesis and 14 right-handed healthy control subjects. Post-stroke patients (hemiplegic group) and normal subjects (control group) repeated a reaching movement 10 times. The variability in average EMG value of each muscle was defined as the average standard deviation of the average rectified values (nARV-SDave). During the reaching movements, the nARV-SDave values was significantly higher in the hemiparesis group than in the control group for the biceps and triceps brachii (P < 0.05). In the hemiparesis group, significant negative correlations between the variability in nARV-SDave values and the Fugl-Meyer assessment scores were observed in all muscle types (rs = −0.46 to −0.76; P < 0.05, P < 0.01). This study identified a direct relationship between the variability in muscle activity and the severity of motor function deficit in post-stroke patients. The selective impact on the biceps and triceps were related to the nature of the reaching task.
Objective: Amusement was introduced for one month and interaction among the elderly and its influence on their physiological function and sleep were investigated. Methods: The subjects were 9 elderly females (age: 89.0 ± 4.7 years old) who periodically visited a day care service center for the elderly. The survey was performed between October 2015 and December 2015. For the amusement, Blackjack was introduced. The survey period was comprised of 3 amusement introduction periods: pre-amusement, and one week and one month after amusement introduction. In each period, the heart rate (HR), sympathetic nerve activity (CSI), and parasympathetic nerve activity (CVI) were measured during amusement, and the difference in the salivary amylase level between before and after amusement was determined. The sleep efficiency and sleeping hours were measured at night of the days with amusement. Repeated measures one-way ANOVA was performed regarding the survey period as a factor and HR, CSI, CVI, sleep efficiency, sleeping hours, and difference in the amylase level as dependent variables. Results: Significant amusement-induced changes were noted in the CVI and salivary amylase level. These were significantly lower at one month after amusement introduction than those in pre-amusement. Conclusion: Amusement-induced laughing and regret or interaction through the amusement influenced their autonomic nerve system and they may have felt comfortable.
Background: Toilet activity is performed every day with a physiological phenomenon so called “excretion”, which is highly necessary. In this study, we used Eye Mark Recorder, a gaze analyzer, to analyze eye movement of elderly people during toilet activities. In addition, we compared the results with those obtained from a preceding study regarding toilet activities in young people.
Result: The toilet activity was divided into three phases: until they sit down, while they are sitting on the bowl, and until they leave the room. Until they sat down and until they left the room, they were looking at the entire environment in the toilet. While they were sitting on the bowl, however, they were mostly looking forward. A similar tendency was observed in young people as well. Furthermore, retention time, degree of dependence on the lower gaze, rate of recognition, as well as an association between the time required for movement and the degree of dependence on the lower gaze were investigated. The elderly people were far more likely to gaze toward the floor compared to the young people.
Conclusions: The results showed which areas the subjects had to look at during 3 toilet-activity phases in order to understand the spatial relation. In toilet activities of the elderly, the rate of gaze toward the floor increased probably due to aging, posture and decreased balancing ability. We will need to further investigate associations between the subjects' age, posture, balancing ability and the gaze during the toilet activities.
Background: Physical activity (PA) has been found to affect the fear of falling (FOF). Although objective measures can improve the accuracy of measurement compared with subjective measures, previous studies have primarily used self-report measures to assess PA. The relationship between FOF, PA, and health-related quality of life (HRQOL) in elderly people who need long-term care has therefore not been sufficiently clarified.
Purpose: The purpose of this study was to investigate the relationship between FOF, PA, and HRQOL in elderly daycare service users.
Methods: The participants were 39 frail elderly people living at home who regularly used daycare facilities (13 men, 26 women; mean age, 75.1 ± 6.7 years). A cross-sectional study design was used. FOF was assessed using the Japanese version of the Falls Efficacy Scale (FES), PA was measured using a triaxial accelerometer, and HRQOL was assessed using the Japanese version of the Short Form-8 Health Survey. Based on median FES scores, participants were divided into two groups, High FES and Low FES, and then the PA and HRQOL values were compared.
Results: Patients in the Low FES group had significantly less PA (p = 0.019) and lower physical component scores in regard to HRQOL (p = 0.006).
Conclusions: The results of this study suggest the presence of a relationship between low FES scores in elderly daycare service users and less PA and low physical component scores in regard to HRQOL.
We are developing tasks on a laptop computer to enable cheaper and easier driving assessments at medical institutions. The aim of this preliminary study is to characterize the performance of young drivers in the developed tasks. The participants were 42 young licensed drivers who performed a video-based hazard detection task and a visual searching task (Trail Making Test). In the hazard detection task, they were instructed to touch the hazardous events on the computer screen that was likely to become involved in a traffic conflict during a driving video. Results showed that the video included 11 hazards and young drivers detected hazardous events during a particular period of time. For the visual searching tasks, our computer-based TMT had proper cognitive load, which was not found in existing paper-based TMT. Further investigations recruiting subjects from other age groups should be necessary to validate our driving assessment programs.
