The purpose of this study was to evaluate the association between subjective usefulness of pedometer and step count, exercise adherence, and the possibility of a pedometer helping exercise adherence.
The subjects were 106 community-dwelling citizens (mean age±SD, 66±5) who were put on an individual exercise program in addition to walking. The targeted step count was 8000 steps/day. Every subject wore a pedometer that registers 7 days of physical activity.
The rate of adherence was 98.1%, and about 73% of subjects answered that using a pedometer is useful for physical activity. There was no difference in exercise habit at baseline between subjects answering useful or not useful.
Only in the case of females, was step count and prevalence of targeted 8000 steps significantly higher in the group who felt a pedometer was useful than in the group who didn't feel it useful. However, in the group of males who felt the usefulness of a pedometer, step count significantly increased during the 3 months. In addition, the females who reached their targeted step count performed better in the 10 m hurdle walk and 6 min walk than those who could not reach the targeted step count.
The awareness of self-health wellness, without the anxiety of physical fitness and adherence to exercise was higher in the subjects who felt a pedometer was useful than in the subjects who didn't.
The subjects who felt a pedometer was useful achieved their targeted number of steps and increased walking ability and tended to adhere better to physical activity.
It is suggested that a pedometer motivates adherence to physical activity and is useful for helping exercise adherence in the future. However, we need a randomized control trial for determining the relationship between exercise adherence and using a pedometer.

Introduction: In the rehabilitation period following a stroke, rehabilitation therapists must thoroughly evaluate the condition of patients for the purposes of goal-setting and effective training. Postgraduate education in the medical examination of patients after stroke was provided for rehabilitation therapists, and changes in their autonomy during medical examinations were subsequently assessed.
Method: The education consisted mainly of reading case reports about patients who had strokes and learning neurological examination techniques. A total of 35 once-weekly education sessions were provided to rehabilitation therapists working in a convalescent rehabilitation ward. The rehabilitation therapists evaluated their independence with respect to obtaining patient backgrounds, vital signs, physical findings, neurological findings, laboratory results, and basic knowledge of illness at the beginning and end of the education sessions and 6 months after the sessions ended. Each evaluation item was compared according to the time of evaluation.
Results: Rehabilitation therapists’ autonomy over obtaining patient backgrounds, neurological findings, laboratory results, and basic knowledge of illness was greater at the end of the education sessions than at the start of the sessions. Their autonomy over obtaining information in these 4 areas and obtaining physical findings was greater 6 months after the end of the education sessions than at the start of the sessions.
Discussion: We conclude that workplace postgraduate training in the medical examination of patients who have had strokes improves rehabilitation therapists’ autonomy during medical assessments.

Introduction
Recently, an increasing number of registered foreigners get married and bear children in Japan. At the same time, a variety of needs for maternal and child health (MCH) impose burden for medical practitioners. A questionnaire survey was conducted to clarify the situation of MCH service for foreign residents.
Method
Self-report questionnaires developed by “The study group for MCH in a multiethnic and multicultural society” were sent by mail to the pediatricians registered in the Gunma medical association or Gunma pediatric association. In total, target number was 299. The survey period was between 2003/10/6-11/3.
Result
The number of valid response was 167. Out of 167, 155 doctors replied to have experience of caring foreigners. 75% of them had the experience of trouble in communication. For the question of the need of translator, 76.8% of doctors answered “absolutely necessary” or “necessary if the quality of translation is high enough”. Desired competencies for translators were “Accurate translation of diagnosis, hands on of treatment strategy” or “To help taking detailed patient's history”.
For the experience of using MCH handbook in foreign languages, 52.9% of doctors answered “Never used it”.
Discussion
We found that the majority of doctors had difficulty in communicating with foreigners.
To meet the doctors' requirement for the competency of translator, two strategies should be considered. One is to develop professional medical translator through education of basic medical knowledge or Japan's health care system. The other is to train foreigners already engaging in translation.
For communication tools development, user friendly concept should be reflected including 1) adscript of foreign and Japanese languages, 2) illustration usage and 3) eye-friendly materials for elderly. Contents should have explanations including 1) diagnosis and treatment policy for common disease, 2) ways of coping with common symptoms, and 3) the information of a variety of Japan's welfare services.

The purpose of this study was to examine the association between the pedometer-determined steps per day and physical fitness in order to evaluate the usefulness of the pedometer-determined physical activity to help individuals meet the recommended exercise target level of the Ministry of Health, Labour and Welfare (MHLW). The subjects consisted of 222 men and 172 women aged 71 years in community-dwelling elderly. The subjects wore a pedometer for 7 consecutive days to measure daily steps. The functional capacity was assessed based on the Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) and self-reported performance of tasks (stair-climbing and chair-rising). Physical fitness tests included handgrip strength, knee extensor strength, leg extensor power, stepping, one-leg standing time with eyes open and maximal walking speed at 10 m. The men and women took on average 6,561±2,907 and 6,329±2,451 steps/day, respectively. Our subjects seemed to be highly functioning elderly, because the total scores of TMIG-IC (maximum : 13 scores) were on average 12 for men and women. The average of steps/day was significantly correlated with stair-climbing, chair-rising and knee extensor strength in men and women, and with body weight, body mass index (BMI), percent body fat (%Fat) and leg extensor power in women. The BMI and %Fat levels were significantly lower while the handgrip strength and knee extensor strength were significantly higher in women who attained to the level of the pedometer-determined physical activity as recommended by the MHLW.The present study suggests that both men and women who take a lot of steps on a daily basis tend to demonstrate excellent leg strength and thus have a good ability to perform the tasks of daily living. In addition, the degree of obesity tends to be lower in women who regularly take a lot of steps. In addition, the number of daily steps taken has been recognized to be linked to gender, and such a link has also been suggested to be stronger in women than in men.

This prospective study was designed to clarify the association between the incidence of falls and physical fitness in healthy community-dwelling elderly people without history of fall-related injuries within 1-5 years before the baseline assessment. Six hundred and one elderly subjects aged 60-79 years who lived independently participated in baseline assessments from March 2002 to March 2004, and were followed up for one year to detect falling. Demographic items (age and sex), chronic disease, self-rated health, difficulty in performing any activity, tendency to stay at home, body mass index (BMI), %vital capacity, handgrip and knee extension strength, stepping rate, one-leg standing with eyes opened, trunk flexion at sitting position, maximum walking speed, instrumental activity of daily living (IADL), and General Health Questionnaire (GHQ30) were assessed at baseline. Four hundred and eighty-one participants (80.0%) completed the 1-year follow-up.The fall incidence was 13.1%. In men, fallers had lower BMI and decreased maximum walking speed, however, neither showed significant odds ratio (OR) for fall. In women, fallers had lower knee extension strength and the ratio of weak side to strong side (WS/SS ratio) in knee extension strength compared to non-fallers. The age-adjusted OR for fallers in the lowest quartile (knee extension strength＜0.681kg/BW) was 3.07 (95%CI : 1.02-9.22) compared to highest quartile (＞0.980 kg/BW), while the multiple-adjusted OR was not significant (OR＝2.88, 95%CI : 0.94-8.79). However, the multiple-adjusted OR for fallers in the lowest quartile of the WS/SS ratio in knee extension strength (＜0.771) was 4.49 (95%CI : 1.40-14.37) compared to highest quartile (＞0.947).As for conclusion, without history of fall-related injuries, only a weak association between falls and physical fitness was observed in men. In women, the unbalanced knee extension strength was associated with falls. The WS/SS ratio in knee extension strength might be a key factor in predicting falls in women.

There have so far been no studies examining the physical fitness and physical activity (PA), measured using objective measures, in homebound elderly people. The purpose of this study was to examine physical fitness levels and PA patterns and evaluate their relationships in homebound elderly people. In 2004, a total of 3964 community-dwelling elderly aged 65 years and over participated in a base line survey. The subject data were directly collected by in-home interviewer. Subjects were defined as being homebound if they went outdoors less than once a week. However, the subjects who could not go out without assistance due to sickness and/or disability were excluded from the analysis. In 2005, 38 homebound (22 men, 16 women) and 70 non-homebound (33 men, 37 women) older adults who participated in the base line survey were selected. Measurements of physical fitness levels and PA patterns measured using an accelerometer, were taken in 2005. The total steps per day did not significantly differ between homebound and non-homebound men and women. The time spent in 1.8 METs activity (corresponding to activity level 1 of the accelerometer) was significantly higher in women than in men for non-homebound and homebound, respectively. The time spent in lower-, moderate-, and high-intensity PA did not significantly differ between homebound and non-homebound men and women, respectively. Handgrip strength, knee extensor strength, leg extensor power, stepping and maximum walking speed were significantly higher in non-homebound than in homebound men and women. These results suggest that the physical fitness levels of homebound were lower than those of non-homebound, but no difference was observed in the PA levels between homebound and non-homebound.

BACKGROUND: Specific IgE antibodies against the low-molecular-weight carbohydrate antigen that does not bridge IgE molecules on mast cells are not associated with clinical symptoms. Cross reactivity can be determined in allergen-specific IgE detection assays when the carbohydrate structures between pollen allergens and plant derived food allergens are similar; in such cases, false positive results for grain or legume allergens can be reported for pollen allergic patients who are not sensitized to those allergens. This phenomenon arises owing to the presence of cross-reactive carbohydrate determinants (CCDs). OBJECTIVE: This study aimed to assess the impact of CCD interference on the results for pollen allergen-specific IgE antibodies in the general adult population and to perform CCD inhibition tests evaluating the involvement of CCD on samples positive to pollen allergens. METHODS: Serum samples from 322 subjects were tested for IgE antibodies to pollens and CCD. The research subjects were given questionnaires about pollen allergic symptoms to help assess the presence of allergies. Allergen IgE antibodies for Japanese cedar, Japanese cypress, orchard grass, ragweed, MUXF, bromelain, horseradish peroxidase (HRP), and ascorbate oxidase (ASOD) were analyzed. RESULTS: It was observed that among individuals who tested positive to any of the pollen allergens, the positive ratio of CCD-specific IgE antibody was the highest for HRP (13.5%–50.0%). The results from the inhibition tests revealed that CCD was marginally present. Although IgE antibodies for cedar pollen did not react with CCD, IgE antibodies for Japanese cypress, orchard grass, and ragweed might be detected by the presence of CCD. CONCLUSION: The results of the inhibition tests revealed the obvious presence of CCD suggesting its involvement. Considering these findings, careful evaluation of patient IgE results should be performed for Japanese cypress, orchard grass, and ragweed.

Dynamic X-ray (DXR) is a functional imaging technique that uses sequential images obtained by a flat-panel detector (FPD).This article aims to describe the mechanism of DXR and the analysis methods used as well as review the clinical evidence for its use. DXR analyzes dynamic changes on the basis of X-ray translucency and can be used for analysis of diaphragmatic kinetics, ventilation, and lung perfusion. It offers many advantages such as a high temporal resolution and flexibility in body positioning. Many clinical studies have reported the feasibility of DXR and its characteristic findings in pulmonary diseases. DXR may serve as an alternative to pulmonary function tests in patients requiring contact inhibition, including patients with suspected or confirmed coronavirus disease 2019 or other infectious diseases. Thus, DXR has a great potential to play an important role in the clinical setting. Further investigations are needed to utilize DXR more effectively and to establish it as a valuable diagnostic tool.
