Abstract
Objectives The Kihon Checklist (KCL) is valuable for predicting long-term care (LTC) certification. However, the precise association between KCL scores and the temporal dynamics of LTC need certification remains unclear. This study clarified the characteristic trajectory of KCL scores in individuals certified for LTC need. Methods The KCL scores spanning from 2011 to 2019 were obtained from 5630 older individuals, including those certified for LTC need in November 2020, in Iiyama City, Nagano, Japan. We analyzed the KCL score trajectories using a linear mixed model, both before and after propensity score matching. Results Throughout the 9-year observation period, the KCL scores consistently remained higher in the certified group compared to the non-certified group. Notably, a significant score increase occurred within the 3 years preceding LTC certification. Discussion Our findings highlight the effectiveness of continuous surveillance using the KCL in identifying individuals likely to require LTC within a few years.

Abstract
BACKGROUND Today we experience "Super-aged society", and a drastic increase in the number of older people needing assistance is an urgent matter for everyone from medical and socio-economical standpoints. Locomotive organ dysfunction due to musculoskeletal disorders is one of the main problems in these patients. Although the concepts of frailty and sarcopenia have been proposed for functional decline, pain remains the main and non-negligible complaint in these of such disorders. This prospective cohort study aimed to observe the changes of reduced mobility in patients with locomotive disorders and to determine the risk factors for functional deterioration of those patients using statistical modeling. METHODS A cohort of older adults with locomotive disorders who were followed up every 6 months for up to 18 months was organized. Pain, physical findings related to the lower extremities, locomotive function in performing daily tasks, and Geriatric Locomotive Function Scale-25 (GLFS-25) score were collected to predict the progress of deterioration. Group-based trajectory analysis was used to identify subgroups of changes of GLFS-25 scores, and multinomial logistic regression analysis was performed to investigate potential predictors of the GLFS-25 trajectories. RESULTS Overall, 314 participants aged between 65 and 93 years were included. The participants were treated with various combinations of orthopedic conservative treatments on an outpatient basis. The in-group trajectory model analysis revealed a clear differentiation between the four groups. The mild and severe groups generally maintained their GLFD-25 scores, while the moderate group included a fluctuating group and a no change group. This study showed that comorbidity of osteoporosis was related to GLFS-25 score over 18 months. Age was a weak factor to be moderate or severe group, but gender was not. In addition, the number of pain locations, number of weak muscles, one-leg standing time, grip strength and BMI significantly contributed to the change in GLFS-25 score. CONCLUSIONS This study proposes an effective statistical model to monitor locomotive functions and related findings. Pain and comorbid osteoporosis are significant factors that related to functional deterioration of activities. In addition, the study shows a patient group recovers from the progression and their possible contributing factors.

Abstract
OBJECTIVES To investigate whether body mass index (BMI) trajectory, lifestyle and reproductive factors are associated with knee pain risk among middle-aged women. DESIGN Prospective study of the Japan Nurses' Health Study (JNHS). SETTING The JNHS investigates the health of female nurses in Japan. Biennial follow-up questionnaires are mailed to the participants. PARTICIPANTS The 7434 women aged over 40 years who responded to the 10-year self-administered follow-up questionnaire. PRIMARY OUTCOME MEASURE Self-reported knee pain at the 10-year follow-up was the primary outcome. We analysed BMI (normal or overweight) trajectory data from a baseline survey to the 10-year follow-up survey using group-based trajectory modelling. Exposure measurements were BMI trajectory, BMI at age 18 years, lifestyle variables and reproductive history. RESULTS BMI trajectories from baseline to the 10-year follow-up were divided into four groups: remained normal, remained overweight, gained weight or lost weight. At the 10-year follow-up, 1281 women (17.2%) reported knee pain. Multivariable logistic regression analysis revealed that compared with the remained normal group, multivariable-adjusted ORs (95% CI) of knee pain were 1.93 (1.60 to 2.33) for the remained overweight group, 1.60 (1.23 to 2.08) for the gained weight group and 1.40 (0.88 to 2.21) for the lost weight group. The attributable risk percent (95% CI) of the remained overweight group was 48.1% (37.3% to 57.0%) compared with the reference group of remained normal. Alcohol intake at baseline was significantly associated with knee pain. CONCLUSIONS The lost weight group had a lower risk than the remained overweight group and the gained weight group and did not carry statistically significant risks for knee pain. Weight reduction and maintaining a normal BMI in middle age was important for preventing knee pain in women.

Abstract
Background The aim of this study was to investigate the correlation between radiographic measurement in lumbar spine and clinical information including symptoms or results of functional testing using a baseline data of longitudinal cohort study. Methods A total of 314 elderly subjects were recruited from 5 orthopedic clinics or affiliated facilities. Data for the present investigation were collected via an interviewer-administered questionnaire, which included questions on past medical history, drug history, pain area. And also results of functional testing and X-ray imaging of the lumbar spine were collected. Analysis was carried out to determine any correlation between results of X-ray imaging of the lumbar spine and other collected data, and sorted regarding Akaike Information Criterion (AIC). The correlations among these variables and odds ratio were also analyzed. Results T12/L1% disc height showed a minimum AIC value with buttock pain (− 4.57) and history of vertebral fracture (− 4.05). The L1/L2, L2/L3, and L3/L4% disc height had a minimal AIC value with knee pain (− 4.11, − 13.3, − 3.15, respectively), and odds ratio of knee pain were 3.5, 3.8, and 2.7, respectively. Conclusions Correlation was recognized between the T12/L1% disc height and both buttock pain and previous vertebral fractures, and the L1/L2, L2/L3, and L3/L4% disc height showed a correlation with knee pain. Especially the L2/L3% disc height and knee pain had a strong correlation. It was suggested that these findings may provide additional basis to the concept that lumbar spinal lesion associates with knee pain clinically.

Abstract
Osteoarthritis (OA) of the knee is one of the main causes of mobility decline in the elderly. Non-surgical treatments such as administration of supplements to strengthen the joint cartilage matrix have become popular not only for pain relief but also for joint preservation. Glucosamine has been used in many countries based on the increasing evidence of its effectiveness for OA. Although there are many previous studies and systematic reviews, the findings vary and different conclusions have been drawn. We aimed to review recent randomized controlled trials on glucosamine for knee OA to reveal up-to-date findings about this supplement. We also performed a meta-analysis of some of the outcomes to overcome the unsolved bias in each study. Eighteen articles written between 2003 and 2016 were analyzed. Many used visual analogue scale (VAS) pain scores and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), which were assessed in our meta-analysis. We found a marginally favorable effect of glucosamine on VAS pain scores. The effect on knee function, as measured by the WOMAC, was small and not significant. A newly established knee OA scale, the Japanese Knee Osteoarthritis Measure (JKOM), is commonly used in Japan. Although the number of subjects was small, the JKOM meta-analysis indicated that glucosamine is superior to a placebo in alleviating knee OA symptoms. Given this, we concluded that glucosamine has the potential to alleviate knee OA pain. Further studies are needed to evaluate the effect of glucosamine on knee function and joint preservation, as well as to evaluate the combined effect with other components, such as chondroitin.

Abstract
BACKGROUND Ageing is associated with a decline of motor function and ability to perform daily activities. Locomotive disorders are one of the major disorders resulting in adverse health condition in elderly people. Concept of Locomotive syndrome (LoS) was proposed to tackle the problems and prolong healthy life expectancy of people with locomotive disorders. To develop intervention strategy for LoS it is mandatory to investigate impairments, functional disabilities which people with locomotive disorder experience and to examine relationships among these parameters. For this purpose we have developed Geriatric Locomotive Function Scale-25 (GLFS-25). Though several physical performance tests were reported for identification or monitoring the severity of LoS, there are few studies reported on characteristics of disability which people with locomotive disorders experience. The aim of this study was to report the characteristics of ADL disabilities in elderly people with locomotive disorders in terms of numbers and degree of activity limitations. METHODS We organized a cohort study and recruited 314 participants aged 65 years and over from five orthopedic clinics or nursing care facilities. This was a cross-sectional study to use the baseline data of such cohort. ADL disabilities were assessed using GLFS-25 scale arranging the GLFS-25 scores in ordinal levels using "R language" program. Numbers and degrees of activity limitations were determined and compared among the levels. Frequency of limitation in activities regarding social activity, housework, locomotion, mobility and self-care was compared among across the disability level. RESULTS The GLFS-25 score was mathematically categorized into 7 levels. The number of activity limitations and the degrees of each activity limitation were significantly greater in high GLFS-25 levels than in low levels. Difficulties in mobility appeared in less severe level, difficulties in domestic and social life appeared in moderately severe level, and difficulties in self-care appeared in advanced level. CONCLUSIONS High GLFS-25 score represented high degree of disability on ADLs. Concordant increase of numbers of activity limitation and severity progression in activity limitation may contribute to progression of disability. Activity limitation may occur in the following order: sports activity, walking, transferring, and self-care.

Abstract
The aim of this study was to compare the efficacy of elcatonin injections and oral nonsteroidal anti-inflammatory drugs (NSAIDs) for patients with osteoporosis who have acute lumbar pain after experiencing new vertebral compression fractures. Two hundred twenty-eight Japanese female patients (mean age 77.3 years) with acute lumbar pain from osteoporotic vertebral fractures were randomly divided into two groups. Patients in one group were given an NSAID (NSAIDs group) and patients in the other group were given weekly intramuscular injections of 20 units of elcatonin (elcatonin group). All patients underwent follow-up examinations up to 6 weeks from the start of the trial. Outcome measures were the level of functional impairment according to the Japan Questionnaire for Osteoporotic Pain (JQ22), the Roland-Morris Disability Questionnaire (RDQ), and a visual analog scale (VAS) of pain intensity. Statistical analyses focused on (1) the time course of pain and functional level using linear mixed effects models to analyze the longitudinal data and (2) the effectiveness of elcatonin injection with mean difference values and 95 % confidence intervals. Significant differences were seen over time between the initial values and the postintervention values (4 and 6 weeks) in JQ22, RDQ, and VAS scores (effect size d > 0.4) in each group. The mean differences between the elcatonin group and the NSAIDs group in each measure at 4 and 6 weeks were -4.8 and -8.3 for the JQ22, -1.3 and -2.6 for the RDQ, and -11.3 and -11.5 for the VAS, shifted to elcatonin. Once weekly elcatonin injection was more effective than NSAIDs for treating acute lumbar pain and improving mobility in Japanese women with osteoporotic vertebral fractures.

Abstract
The aim of the present study is to evaluate the outcome of hand-sewn esophagogastric anastomosis during radical esophagectomy for esophageal cancer. The outcomes of 467 consecutive esophageal cancer patients who underwent cervical esophagogastric anastomosis using interrupted and double-layered sutures after radical esophagectomy via right thoracotomy or thoracoscopic surgery were retrospectively reviewed. Anastomotic leakage, including conduit necrosis, occurred in 11 of 467 patients (2.4%); 7 of 11 (63.6%) cases experienced only minor leakage, whereas the other four (36.4%) patients had major leakage that required surgical or radiologic intervention, including two patients of conduit necrosis. Anastomotic leakages were more frequently observed after retrosternal reconstruction compared with the posterior mediastinal route (P < 0.0001). The median time to healing of leakage was 40 days (range: 14-97 days). Two patients (2/467, 0.4%) died in the hospital due to sepsis caused by the leakage and conduit necrosis. Twelve patients (2.6%) developed anastomotic stenosis, which was improved by dilatation in all patients. Hand-sewn cervical esophagogastric anastomosis is a stable and highly safe method of radical esophagectomy for esophageal cancer.

Abstract
BACKGROUND Locomotive disorders are one of the main causative pathologies for the condition requiring assistance on activities of daily living (ADL). Although psychological concerns such as feeling of depression and anxiety are prevalent in elderly people, the causal relation among motor function, ADL disability, and psychological concerns is controversial. PURPOSE Purpose of this study was to investigate causal relationship among motor function, ADL disability, and psychological concerns in elderly people with locomotive disorders. METHODS The data for this study were from a community-dwelling sample of 314 elderly persons with locomotive disorders aged 65 and older who visited orthopedic clinics and/or affiliated institutions. Motor function was assessed by one-leg standing time with eyes open, leg extension power and grip power. We assessed ADL disability using the 25-question Geriatric Locomotive Function Scale (GLFS-25), and psychological concerns by three self-reported questions. We constructed two models and tested fitness of the models to the data using a structural equation modeling (SEM). Model 1: motor function affects ADL disability and ADL disability affects psychological concerns, Model 2: motor function affects psychological concerns and psychological concerns affects ADL disability. RESULTS The fit indices were chi-square = 23.152 (p = 0.081), RMSEA = 0.042, GFI = 0.981, AGFI = 0.955, CFI = 0.987 for Model 1, and chi-square = 84.583 (p < 0.001), RMSEA = 0.119, GFI = 0.935, AGFI = 0.854, CFI = 0.892 for Model 2. These fit indices indicated a good fit of the model 1 and inadequate fit of model 2 to the data. CONCLUSION Decline of motor function contributed toward psychological concerns via ADL disability in elderly people with locomotive disorders.

Abstract
This study investigated whether an intestinal epithelial culture method can be applied to mouse and human esophageal cultures. The esophagi harvested from 1-day-old mice and adult humans were maintained in collagen gels. A commercially available culture medium for human embryonic stem cells was used for the human esophageal culture. We discovered that the intestinal epithelial culture method can be successfully applied to both mouse and human esophageal cultures. The long-term cultured esophageal organoids were rod-like luminal structures lined with myofibroblasts. We discovered that regeneration of the esophageal mucosal surface can be almost completely achieved in vitro, and the advantage of this method is that organoid cultures may be generated using host-derived fibroblasts as a niche. This method is a promising tool for mouse and human research in intestinal biology, carcinogenesis, and regenerative medicine.

Abstract
Stroke patients suffer from gait disturbance due to altered leg muscle actions. Many kinesiological studies have investigated muscle actions, but the metabolic activity of muscles in stroke patients remains to be investigated. We therefore evaluated energy consumption in lower extremity muscles during level walking in hemiparetic individuals. Glucose uptake was measured by positron emission tomography (PET) using (18)F-fluorodeoxyglucose ((18)F-FDG) in eight hemiparetic (mean age: 56 years) and 11 healthy (mean age: 26 years) participants. Standardized uptake ratio (SUR) was computed in each muscle to express the (18)F-FDG-uptake level. SUR was compared across gluteal, thigh, and lower leg muscles and across individual muscles within each muscle group. For each muscle, SUR was compared among the paretic limb of hemiparetic participants, the non-paretic limb of hemiparetic participants, and the right limb of healthy participants. In paretic limbs, mean SUR did not differ between the three muscle groups, or between individual muscles within each muscle group. SURs of paretic lower leg muscles and gluteus minimus muscle were significantly smaller than those of non-paretic limb and healthy participants (p < 0.05). In the non-paretic limb of hemiparetic participants, SUR of the lower leg muscles was larger than that of the thigh muscles (p < 0.05). Unexpectedly, SURs of medial hamstring and posterior tibial muscles were larger in the non-paretic limb of hemiparetic participants, compared to the right limb of healthy participants (p < 0.05). (18)F-FDG PET is useful to evaluate energy consumption levels of lower extremity muscles during level walking in hemiparetic individuals.

Abstract
We have developed a system for monitoring the health of elderly people living at home. Infrared and other sensor outputs are collected using a monitoring program installed on a personal computer (PC) in the home at a sampling rate of 1 Hz. Once each day, the data are transferred to a server through the Internet using a cable television (TV) connection. An elderly subject was monitored for a 12-day baseline period and completed a daily questionnaire about her activities. This enabled us to identify the rhythm of daily living (sleeping, 23:00–04:59; getting up/breakfast, 05:00–08:59; indoor activities/going out, 09:00–16:59; and dinner/going to bed, 17:00–22:59) and the average outputs from the sensors in the rooms. The subject was then monitored for a further six months. By identifying sensor output counts outside the limits of mean ±3SD, we were able to detect atypical days. During the six-month monitoring period, 29 atypical days were detected. We suggest that the monitoring system may be effective in tele-rehabilitation.

Abstract
The increasing elderly population has a great impact on public health, and it is important to understand the progression of musculoskeletal disorders seen in this population. To establish useful preventative methods for such locomotive disorders, we must detect early changes in these individuals and identify those at risk in order to implement early interventions. The purpose of this review was: (1) to introduce an operational definition of locomotion dysfunction to prevent a care-need condition, and to verify its validity through a prospective cohort study, and (2) to review the indication of exercise intervention for multiple musculoskeletal involvements from the preceding literature. We developed a measurement scale called the Geriatric Locomotive Function Scale (GLFS)-25, which clearly reflects the degree of functional deterioration. We used it in a prospective cohort study of 314 patients recruited from 5 clinics or nursing care facilities and investigated the relationship of the GLFS-25 with 46 variables covering various clinical manifestations. The results clearly revealed that the change in the GLFS-25 classification reflected a common pattern seen in those with locomotive dysfunction. Recently, several important movements regarding physical activity and its public promotion have been advocated by international health organizations and journal publishers. Though it has not been confirmed yet that complex musculoskeletal diseases can be treated using therapeutic exercise, the promotion of physical activity appears promising. The degree of activity limitation in aged individuals with locomotive disorders can be evaluated using this scale, which may be useful in predicting the effectiveness of future interventions.

Abstract
BACKGROUND Motor dysfunction is a major reason why the elderly lose their independence in their daily lives. The concept of locomotive syndrome has been proposed to describe the risk of mobility dependence caused by various locomotive organ disorders. The preservation of locomotive organs is now socially important in the middle-aged and geriatric population. Therefore, it is important to establish a screening program to evaluate motor function and related quality of life in a wide range of ages. METHODS We propose a new set of pre-existing scales (the Two-Step test, Stand-Up test, and 25-question Geriatric Locomotive Function Scale) as screening tools to identify the population at high risk for locomotive syndrome. We performed a preliminary survey on 777 subjects who had no apparent disorders related to motor function. We also examined the reliability of the Two-Step test and Stand-Up test. RESULTS We found that each scale did not show ceiling or floor effects in various age groups. Because the correlations between the three scales were significant but weak, we assume that each scale covers different aspects of mobility. The test-retest reliability was found to be satisfactory for the Two-Step test and the Stand-Up test. CONCLUSION Our results suggest that our "Short Test Battery for Locomotive syndrome" is a feasible and reliable tool for screening the adult population as a preventative strategy for locomotive syndrome in a super-aged society.

Abstract
OBJECTIVE To establish the cutoff time for the one-leg standing (OLS) test (with eyes open) to use when screening elderly people for locomotive syndrome. METHODS Patients visiting orthopedic clinics and healthy volunteers, all ≥65 years old, were recruited. Participants were asked to complete the 25-question Geriatric Locomotive Function Scale (GLFS-25) and then underwent the OLS test. Using the previously determined GLFS-25 cutoff value, participants were divided into two groups: the locomotive and the non-locomotive syndrome groups (GLFS-25 scores of ≥16 and <16, respectively). Conventional receiver operating characteristic curve (ROC) analysis was used to calculate the optimal cutoff time for the OLS. RESULTS Data from 880 individuals (261 men, 619 women; mean age (SD), 77 (6) years; range 65-96 years) were analyzed; 497 were in the locomotive syndrome group and 383 were in the non-locomotive syndrome group. A significant difference was seen between each group mean for individual average (IA) OLS times (IA-OLS: the average of the OLS times obtained for both legs of an individual). According to ROC analysis without age adjustment, when the IA-OLS time was ~9 s, the sum of the sensitivity and specificity of the test was highest. However, because of a statistically significant difference in IA-OLS time among the three age groups (aged ≤70, aged >70 and ≤75, and aged >75), we determined the optimal cutoff value for IA-OLS time for each of the three age groups using ROC analysis. According to additional ROC analysis, the optimal cutoff for IA-OLS time was 19 s for individuals aged ≤70, 10 s for individuals aged >70 and ≤75, and 6 s for individuals aged >75 when screening elderly persons for locomotive syndrome. CONCLUSIONS We propose using a GLFS-25 score of 16 and/or a cutoff for the IA-OLS time of 19 s for individuals aged ≤70, 10 s for individuals aged >70 and ≤75, and 6 s for individuals aged >75 when screening elderly persons to determine who should receive medical intervention or undergoing training programs.

Abstract
The objective of this study was to record the clinical course of osteoporosis over time in Japanese women. We hypothesized that successful control of acute pain associated with osteoporosis will allow better treatment for health-related problems. To confirm this working hypothesis, we developed the Japan Questionnaire for Osteoporotic Pain (JQ22) to measure health status associated with osteoporosis. We examined the validity and reliability of the JQ22 compared with the current gold standard scale for back pain, the Roland Morris questionnaire (RDQ). A total of 125 women who were more than 65 years old, had an acute back pain episode, and had a fragile vertebral fracture confirmed by X-ray and clinical signs, participated in this study. The psychometric analyses for validity and reliability were tested for the JQ22 and the RDQ. The time course up to 6 weeks was observed by investigating both changes in pain characteristics and its influence on related activities and social participation. Cronbach's alpha coefficient was 0.979 and 0.919 for the JQ22 and RDQ, respectively. The Akaike Information Criterion (AIC) indicated that the JQ22 items were separated into four domains, which were sequentially arranged at the baseline and subsequently changed. This structure reflected osteoporotic back characteristics covering a range from pain to social activities. The JQ22 was shown to be a valid and reliable scale for patient-based measurement of osteoporotic back pain. It also revealed both changes in pain characteristics and the influence of pain on related activities and participation.

Abstract
STUDY DESIGN Retrospective study at a rehabilitation center. OBJECTIVES Patients with spinal cord injury, even if they are wheelchair users, sometimes suffer from fractures of the lower limb bones. As their bones are too weak to have surgery, and because a precise reduction is not required for restoration, such patients are often indicated for conservative treatment. This case series study investigated the use of a hinged, soft-plastic brace as a conservative approach to treating fractures of the lower extremities of patients with spinal cord injury. SETTING National Rehabilitation Center, Japan. METHODS Fifteen patients (male, n=10; female, n=5; average age, 52.7 years) with 19 fractures of the femur or the tibia who were treated with a newly-developed hinged, soft-plastic brace were studied. All of them used wheelchairs. We analyzed the time taken for fracture union and for wearing orthotics, degree of malalignment, femorotibial angle and side effects. RESULTS The fractures in this series were caused by relatively low-energy impact. The average time taken for fracture union was 80.1 (37-189) days, and the average amount of time spent wearing orthotics was 77.9 (42-197) days. On final X-ray imaging, the average femorotibial angle was 176.9° (s.d. ±8.90), and 15° of misalignment in the sagittal plane occurred in one patient. CONCLUSION A hinged, soft-plastic brace is a useful option as a conservative approach for treating fractures of the lower extremities in patients with spinal cord injury.

Abstract
The objective of this study was to examine the effect of a nonsteroidal anti-inflammatory drug (NSAID) plaster for knee osteoarthritis among Japanese patients. An open-labeled, randomized, controlled, multiclinic trial was performed involving outpatient clinic groups. Two comparative groups-plaster NSAIDs and oral NSAIDs-were randomly allocated. The drugs used were limited to the current top three in both groups in Japan. Treatments were assessed after four weeks and compared with the baseline scores. Outcomes were evaluated by two psychometric measures: Japanese knee osteoarthritis measure, and pain with the visual analogue scale. The total number of patients included in the final evaluation was 165 (87 for the plaster group and 78 for the oral group). Between these two groups there were no significant differences in gender, age, body height and weight, body mass index, and X-ray grading. The subjects in both groups showed improvements in both scores at the end of intervention. The differences in the improvements in scores between the two groups were not significant, though the mean rank score and the 95% CI of the plaster group were slightly better than those of the oral group. In conclusion, the local application of a plaster with NSAIDs leads to the same level of improvement in knee osteoarthritis as oral NSAIDs.

In order to examine if the addition of an arch support could improve the biomechanical effect of the laterally wedged insole, three-dimensional gait analysis was performed on 20 healthy volunteers. Kinetic and kinematic parameters at the knee and subtalar joints were compared among the following four types of insoles; a 5-mm thick flat insole, a flat insole with an arch support (AS), a 6 degrees inclined laterally wedged insole (LW), and a laterally wedged insole with an arch support (LWAS). The knee adduction moment averaged for the entire stance phase was reduced by the use of LW and LWAS by 7.7% and 13.3%, respectively, from that with FLAT. The difference in knee adduction moment between LW and LWAS was most obvious in the late stance, which was ascribed to the difference in the progression angle between those insoles. The analyses also revealed that LW tended to increase step width, and that such an increase was completely eliminated by the addition of an arch support to LW. This reduction of step width could be another mechanism for the further reduction of the moment with LWAS. The analyses of biomechanical parameters at the subtalar joints suggested that LWAS allowed the subject to walk in a more natural manner, while exerting greater biomechanical effects than LW. Thus, the addition of an arch support to the laterally wedged insole reduced knee adduction moment more efficiently, possibly through the elimination of potential negative effects of the laterally wedged insole.

Abstract
OBJECTIVES To examine the effect of home-based exercise on knee osteoarthritis among Japanese in comparison with that of nonsteroidal antiinflammatory drugs (NSAIDs). DESIGN An open-labeled, randomized, controlled, multiclinic trial compared home-based quadriceps exercise with NSAIDs. Treatments were basically evaluated after 8 wks and compared with the baseline scores. Outcomes were evaluated with a set of psychometric measurements including the Western Ontario and McMaster Universities Arthritis Index (WOMAC), 36-Item Short-Form Health Survey (SF-36), Japanese Knee Osteoarthritis Measure (JKOM), and pain with the visual analog scale. RESULTS A total of 142 patients entered this trial to provide the baseline data. After 21 cases withdrew, the final number analyzed was 121 cases: 63 for the exercise group and 58 for the NSAIDs group. Between these two groups, there was no significant difference in gender, age, body height and weight, body mass index, or each score at baseline. The subjects in both groups showed improvements in all scores at the end of intervention. The difference in improvement rate of each score between the two groups was not statistically significant, though the mean rank score measured with JKOM in the exercise was slightly better than that of the NSAIDs. CONCLUSIONS Home-based exercise using quadriceps strengthening improves knee osteoarthritis no less than NSAIDs.

Abstract
Skeletal dysplasias induced by mutations in the collagen 2 gene (the so-called "type 2 collagenopathies") form a wide spectrum in severity and are distinguished by subtle clinical and radiographic differential signs. The unifying features are predominant involvement of the vertebral bodies and the epiphyses of the long bones ("spondylo-epiphyseal" pattern). A mild degree of metaphyseal dysplasia can be seen in the so-called Strudwick variant of spondyloepimetaphyseal dysplasia and is generally mild or absent in other forms. We report here on four individuals with COL2A1 mutations associated with marked metaphyseal involvement with only mild epiphyseal and spondylar changes. One patient who carried a Gly283Arg substitution had a pattern of metaphyseal dysplasia that corresponded precisely to what was termed "Murdoch type metaphyseal dysplasia" in 1960s and was renamed Strudwick type SEMD in 1980s; the second patient carried a Gly181Arg substitution and had severe metaphyseal dysplasia with fractures at the metaphyses reminiscent of the "corner fractures" or Sutcliffe type spondylometaphyseal dysplasia. The third patient also had major metaphyseal involvement but more epiphyseal changes than the others in this study and had a Gly922Arg mutation in COL2A1. The final patient had a small in-frame deletion and unusually ballooned and distorted metaphyses. While it remains true that most individuals with COL2A1 mutations have chondrodysplasia with a spondylo-epiphyseal pattern, metaphyseal involvement is not incompatible with a COL2A1 dysplasia and mutation analysis can be indicated. The observation of these individuals with metaphyseal dysplasia indicates that the phenotypic spectrum associated with mutations in type 2 collagen, the main cartilage protein, is even wider than hitherto assumed.

Abstract
OBJECTIVE Aberrant expression of maspin protein related to DNA hypomethylation in the promoter region is frequently observed in gallbladder carcinomas, whereas the non-tumorous gallbladder epithelium is maspin negative. We investigated maspin expression in non-tumorous gallbladder epithelium in patients with cholelithiasis. METHODS An immunohistochemical study of maspin expression was performed in 69 patients with cholelithiasis and 30 patients with gastric cancer without cholelithiasis. RESULTS Immunoreactivity for maspin was observed in focal and patchy regions of the gallbladder epithelium. Positive immunoreactivity for maspin was significantly associated with the presence of intestinal metaplasia in patients with cholelithiasis (p<0.05). CONCLUSION The high incidence of aberrant maspin expression in both intestinal metaplasia and carcinoma of the gallbladder supports the assumption that intestinal metaplasia of the gallbladder may predispose to gallbladder carcinoma.

Abstract
We examined whether we could identify activity patterns of elderly people in a nursing home from sensor outputs of an infrared monitoring system. The subjects consisted of three elderly people. A single passive infrared sensor installed on the ceiling of each subject's usual dwelling room provided digital output whenever the subject moved. The subjects' actual daily activities were established from questionnaires with which patients documented their living patterns for each of 7 days. Activities were classed as sleeping, getting up/breakfast, indoor activities/going out, and dinner/going to bed. The mean +/- 2 standard deviations (SDs) of the sensor outputs on each day for each period of indoor activity was used to distinguish between normal and aberrant activities. Days on which sensor outputs exceeded the means +/- 2 SDs were regarded as atypical and were identified for each subject over a 28-day period. We were unable to determine the physical condition of the subjects on these atypical days. We were able to identify the pattern of daily indoor living activities and the duration of each class of activity using sensor outputs and a questionnaire. Days were assumed to be atypical when sensor outputs deviated from the normal pattern.

Abstract
Most esophageal carcinosarcomas are diagnosed as so-called carcinosarcoma, in which individual elements may be derived from a single common ancestor cell, and there have been a few reports describing true carcinosarcoma originating from two individual stem cells. We describe a case of esophageal carcinosarcoma exhibiting neoplastic osteoid formation. Immunoreactivity for vimentin and p53 was limited to only the sarcomatous component and was absent in the carcinomatous component. Furthermore, a point mutation in exon 7 of the p53 gene was observed only in the sarcomatous component. Both sarcoma and carcinoma cells distinctively metastasized to different lymph nodes. These observations led us to diagnose the esophageal tumor as a true carcinosarcoma.

Abstract
STUDY DESIGN Cross-sectional and comparative investigation using quadriplegics (QP) and nondisabled subjects (ND). OBJECTIVE To evaluate cardiorespiratory responses during passive walking-like exercise (PWE) in QP. SETTING National Rehabilitation Center for Persons with Disabilities in Japan. METHOD The subjects were seven male QP with complete lesion (age: 27.0 +/- 5.4, injured level: C6-C7) and six male ND (age: 26.3 +/- 4.5). Cardiorespiratory responses were measured until voluntary fatigue during PWE, the rhythmical activity of paralyzed lower limbs synchronized with arm movements. RESULTS There were no significant differences in oxygen consumption (VO(2)), pulmonary ventilation (VE), heart rate (HR) and oxygen pulse (O(2) pulse) between QP and ND during PWE. ND showed increased ventilatory equivalent for oxygen (VE/VO(2) ratio) during exercise, while QP showed a significantly greater respiratory rate (RR) during exercise than ND (P < 0.05). CONCLUSION PWE elicited an increase in VO(2) with workload increment in QP similar to ND. However, higher RR suggested the intrinsic dysfunction of RR control during submaximal exercise in QP. From these results, it was thought that respiratory response would be the restriction factor of efficient oxygen transportation during PWE in QP.

Abstract
OBJECTIVE We describe a new outcome measure for Japanese patients with knee osteoarthritis, the Japanese Knee Osteoarthritis Measure (JKOM). METHODS The outcome measure was designed to incorporate the concepts of the World Health Organization's International Classification of Functioning, Disability and Health 2001, and to reflect the specific Japanese cultural lifestyle, which differs from Western countries. To examine the validity and reliability of this measure and to determine the underlying set of measures, psychometric measurements including factor analysis were conducted in comparison with 2 other health related scales, the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The following psychometric properties were tested with this new measure: test and retest reliability, internal consistency, content validity, construct validity, and criterion related validity. RESULTS The measure was proved to have sufficient reliability and validity by means of statistical evaluation and comparison with other health related scales. Three domains are clearly separated on the loading pattern by factor analysis: pain, limitation in mobility related to daily activity, and restriction of participation in social life and health perception. CONCLUSION The JKOM, a new knee OA measure, has sufficient reliability and validity for studies of the clinical outcomes of Japanese people with knee OA.

Abstract
The health-related QOL (HRQOL) has been used extensively in clinical and epidemiological research and health service studies. Especially, the Medical Outcome Study Short-form 36-Item Health Survey (SF-36) is a widely used health status measure. However, a Korean version has not been developed and tested yet. The purpose of this study was to develop a Korean version of the Short-form Health Survey (SF-36) for use in health related quality of life measurements for Korean elderly people. SF-36 data from 90 healthy elderly people using Social Education Service and 120 elderly patients using a day care service in Seoul, Korea, were examined. We translated SF-36 version 2.0 into Korean and assessed its reliability and validity. In the results, the content validity and discriminant validity were found to be satisfactory. Cronbach's alpha coefficients ranged from 0.9298 to 0.9383. The test-retest reliability coefficients ranged from 0.710 to 0.895. In addition, the utility was examined by testing the correlation between the health-related QOL and related factors (sex, age, motor function, ability of daily life) among the elderly people. The present findings suggested that the Korean version of SF-36 would be useful as a measure of the health related QOL in Korean elderly people.

Abstract
It is necessary and important to quantify the handicap sustained by individuals with spinal cord injury (SCI); however, few instruments are available to measure the level of the disability. One of the best developed and most often used measures is the Craig Handicap Assessment and Reporting Technique (CHART). Nevertheless, a Japanese version has not yet been developed and tested for SCI individuals. The purpose of this study was to develop a Japanese version of the CHART (CHART-J) and to investigate its test-retest reliability and discriminant validity in SCI in Japan. Fifty-four individuals with SCI participated in the test-retest reliability study and 293 participated in the discriminant validity analysis. We have shown that the test-retest reliability coefficients of the CHART-J range from 0.57 to 1.00. In addition, its discriminant validity is acceptable for individuals with SCI in Japan. Therefore, the CHART-J is useful as a measure of disability for Japanese individuals with SCI.

Abstract
Nakada (1988) divided senile postural deformities into four types by visual observation: an extended type, an S-shaped type, a flexed type, and a hand-on-the-lap type. The purpose of this study was to investigate the inter-rater reliability and the discriminant validity of assessing the elderly spinal posture using a posture-measuring device developed by us and dividing postural deformities into the four types of Nakada's classification. Seventy-seven elderly persons (52 women and 25 men) who lived independently participated in the study. The average age of the subjects was 73 years (range, 65 to 84 years). The type of the senile postural deformity was determined by three judges using our posture-measuring device in combination with Nakada's classification. The rate of agreement of the classification was 92.2%. This method had a significantly high rate of inter-rater reliability. The thoracic kyphotic angle was larger in the S-shaped type than in the normal, extended type, and flexed type. The lumbar lordotic angle was also larger in the S-shaped type than in the extended type, flexed type, and hand-on-the-lap type. In the hand-on-the-lap type, the mean of the lumbar lordotic angle was much smaller. The lumbosacral angle was smaller in the extended type than in the normal, S-shaped type, and flexed type. With the analysis of x-ray photographs, this method appeared to have discriminant validity as a measure of senile postural deformity. The combination of our posture-measuring device and Nakada's classification would be useful to classify senile postural deformities in mass examinations.

We have developed an automatic remote system for use in monitoring the health of independent elderly people living in conventional homes. In this study, a monitoring system was installed and evaluated in the house of one subject to test the feasibility of determining activities from sensor outputs. Over a period of 6 months, it was found that total counts from all sensor outputs matched the concurrently acquired data on physical activity obtained from a pedometer. Performance of each basic activity of daily living could be confirmed from the sensor output records.

Abstract
We analyzed muscular activity of the lower extremities during level walking using positron emission tomography (PET) with (18)F-fluorodeoxyglucose ((18)F-FDG). We examined 17 healthy male subjects; 11 were assigned to a walking group and 6 to a resting group. After (18)F-FDG injection, the walking group subjects walked at a free speed for 15 min. A whole-body image was then obtained by a PET camera, and the standardized uptake ratio (SUR) was computed for each muscle. The SUR for each muscle of the walking group was compared with that for the corresponding muscles in the resting group. The level of muscular activity of all the muscles we examined were higher during level walking than when resting. The activity of the lower leg muscles was higher than that of the thigh muscles during level walking. The muscular activity of the soleus was highest among all the muscles examined. Among the gluteal muscles, the muscular activity of the gluteus minimus was higher than that of the gluteus maximus and gluteus medius. The concurrent validity of measuring muscular activity of the lower extremity during level walking by the PET method using (18)F-FDG was demonstrated.

Abstract
We examined the relationship of health factors and social support to life satisfaction in older adults dwelling in a rural town. The gender difference in variables related to life satisfaction was also discussed in this study. One hundred and forty-two older adults (86 females and 56 males) who completed a self-administered questionnaire and participated in a health examination in 1998 or 1999 comprised the study participants. The t-test and chi-square test were used to assess the differences between the two genders. Correlation measure and multiple regression analysis were used to assess the relationship between life satisfaction and other health related or socially related factors for each gender. Significant gender differences were observed in living status and several health related factors. According to the results of the multiple regression analyses, life satisfaction was related to mental health and age in females, while it was related to mental health status and social support from others in males. Gender differences in the variables associated with life satisfaction were observed among the community-dwelling older adults. These data suggest the importance of mental health for older adults. When preparing health promotion strategies for older adults, results of gender differences as they related to social support and life satisfaction should be applied in practice.

Abstract
The objective of this study was to evaluate the therapeutic usefulness of chemoradiotherapy (CRT) followed by surgery in patients with clinically T4 (cT4) esophageal cancer involving adjacent organs such as the trachea, main bronchi, and large vessels. Thirty-seven patients with cT4 squamous cell carcinoma of the thoracic esophagus were enrolled in this study. The CRT regimen comprised cisplatin (70 mg/m2) on day 1, 5-fluorouracil (700 mg/m2) on days 1-4 and external irradiation (200 cGy/day, total 30 Gy) on either days 8-26 (sequential schedule, n=15) or days 1-19 (concurrent schedule, n022). Two courses of CRT were given. The results of CRT were complete response in nine patients, partial response in 19, no change in three (minor response in two), and progressive disease in six patients. The median response duration in all responders was 172 days (range: 56-2469, n=19). After CRT, 13 patients received surgery. In 12 of these patients, tumors were completely resected. Histopathologic examination of the resected specimen revealed a discrepancy between clinical response and histopathologic effect. The median duration of survival and the 1-, 2- and 5-year survival rates were 304 days (84-3155), 45%, 35% and 23% in all patients, respectively, 866 days (190-3155), 83%, 83% and 57% in the 13 patients whose tumors were resected, and 187 days (84--2630), 25%, 5% and 5% in the 24 patients whose tumors were not resected. Grade 3 toxicity, especially hematological reactions, was noted in 13.5% (5/37) of the patients. There was one toxicity-related death (sepsis). A good outcome may be obtained with CRT, followed by surgery when feasible. However, CRT can cause toxic reactions, and close monitoring of patients is required.

Abstract
In this study, we have examined the possibility of non-intrusive monitoring at home. We describe the experimental results of the relation between an individual's recorded behavior and the actions detected by the sensors during the course of the subject's daily life. Infrared sensors and the opening of doors and windows and the use of appliances were used. In this paper, it is assumed that the subjects were sleeping when there were no responses by the infrared sensors or when only the bedroom sensor was responding. The sensors were able to detect excretion by using the outputs of the infrared sensor and the water valve of the lavatory, even if a subject did not record it in the time-course of daily life during the investigation. Our findings show that the actions of subjects who stayed at Welfare Techno House (WTH) in Mizusawa could be estimated from outside the house, especially for sleeping and excretion.

Abstract
Calcium (Ca), magnesium (Mg) and zinc (Zn) levels of fingernails were measured in 135 patients with osteogenesis imperfecta (OI) and compared with the sex- and age-matched healthy controls. Zinc levels in OI nails were significantly higher than that in normal subjects, but in cases and controls Ca and Mg levels were not significantly different. The ratios of Ca/Zn and Mg/Zn in OI nails differed significantly from those in controls, but a similar Ca/Mg ratio was found in nails of both groups. These results suggest that Zn levels in fingernails may reflect abnormal Zn metabolism in OI. To determine Zn metabolism changes in OI, further studies are needed.

Abstract
It has been suggested that SIRS are triggered by superfluous pro-inflammatory cytokine production, and that organ injury is caused by uncontrolled inflammatory responses. However, the results of clinical studies, on the usefulness of specific cytokine antagonists and anti-TNF antibodies for the treatment of septic shock, have been unsatisfactory. The reason for this might have been that when uncontrolled inflammatory reactions progressed locally, anti-inflammatory reactions were elevated in the circulated blood by way of CARS, thus the timing of administration and pharmacokinetics did not match clinical course. Recent research has shown that SIRS is always accompanied by CARS, and since it seems to do the amplitude of SIRS and CARS to each other so that there may be a deep valley, if there is a high mountain. We introduce the recent knowledge which indicates that SIRS is a preliminary alert for not only organ dysfunction but also immunosuppression after severe injury or major surgery.

Abstract
Spondylo-epi-metaphyseal dysplasia is a rare skeletal dysplasia showing radiographic abnormalities in the epiphyses and metaphyses of the long and short tubular bones, and in the spine. There are very few reports of a case followed throughout the entire growth period. Here we report the case of a Japanese girl followed from 1 month old to skeletal maturity at 16 years old. She developed progressive kyphoscoliosis at 7 years old, and underwent a surgical correction of the spine at 14 years old. The diagnosis of spondylo-epi-metaphyseal dysplasia was made from examining all the follow-up radiographs showing abnormalities in the spine, long bones and hands involving epiphyses and metaphyses. She had normal stature--a rare finding in this condition.

Abstract
We report on a family in which four females and two males in three generations had a previously undescribed brittle bone disorder that was dominantly transmitted through a maternal line. The cardinal manifestations of the disorder comprised dolichocephaly with frontal bossing, hypoplasia of the midface, postpubertal prognathism, micromelic short stature, coarse trabeculae of the entire skeleton, and bone fragility of variable degrees. Mild spondylar modification and iliac hypoplasia were other hallmarks that were recognized in childhood. The proband, a 19-year-old male, was most severely affected with multiple wormian bones in the calvaria, repetitive fractures, intractable bowing of the legs and forearms, and pseudofractures of the long bones with metaphyseal narrowing. His male cousin was next severely affected with angular deformity restricted to the forearm. The four females were much less affected without angular deformity. The mode of inheritance was thus consistent with either an autosomal dominant trait with sex-influence or an X-linked semidominant trait. Histological bone examination in the proband showed atrophy and fibrous degeneration of the lamellar trabeculae and disorganized chondro-osseous junction, which implied that the disorder involved both intramembranous and enchondral ossifications.

Abstract
The adverse effect of neoadjuvant chemoradiotherapy on the postoperative course in esophageal cancer was studied in 9 patients undergoing neoadjuvant chemoradiotherapy preceding surgery for thoracic esophageal carcinoma possibly involving adjacent organs (neoadjuvant group), and 13 patients undergoing surgery without neoadjuvant therapy for same disease (control group). The two groups were compared for volume of intraoperative hemorrhage, surgical duration, frequency of postoperative morbidity, and for postoperative changes in blood platelet counts, and serum thrombopoietin and interleukin-6 levels. Mean intraoperative blood loss was 1121 g (580-1,662 g) in the neoadjuvant group and 546.5 g (274.7-778.3 g) in controls group (Student's T test: p < 0.01). No significant difference was seen found between the two groups in the degree of postoperative deterioration in cardiopulmonary function or in interleukin-6 levels. Blood platelet counts decreased in both groups until postoperative day 7, but recovery on postoperative day 14 was significantly depressed in the neoadjuvant group compared to controls. Serum thrombopoietin levels were higher in the neoadjuvant group than in controls (Mann-Whitney U-test: p < 0.05). We found that neoadjuvant chemoradiotherapy induces latent postoperative myelosuppression and may lead to intractable infection.

Abstract
Sixty-three male hemiparetic patients in the recovery stage were examined to investigate the relationship between stride length and walking rate during computer-assisted gait training during a period of 4 wk. The maximum walking speed for 10 m was significantly increased from 32.3 to 53.2 m/min on average, and the stride length and walking rate also increased. However, the ratio of stride length to walking rate did not change significantly in 4 wk, with the mean value being 0.0068 m/steps/min, approximately one-half that of healthy adults based on data from previous reports. The ratio of stride length to walking rate for hemiplegic gait was invariant during the 4 wk of computer-assisted gait training, which is also true at different speeds for healthy adults. These results indicate that the maximum walking speed was significantly improved, with an invariant relationship between stride length and walking rate, and suggest that the ratio could be used as an index for gait training.

Abstract
The non-coding control region of mitochondrial DNA (mtDNA), containing the hypervariable regions HV1 and HV2 and the D-loop region, was screened for mutations in 45 gastric tumours (15 tumours each of adenoma, differentiated adenocarcinoma and undifferentiated carcinoma). We found mutations in two of the 45 tumours (4%); a 1 bp A deletion at nucleotide position 248 in a differentiated adenocarcinoma and a G to A transition at nucleotide position 16,129 in an adenoma. We also observed 10 polymorphisms, four of which were not previously recorded. Both mtDNA mutations were present in replication error negative (RER-) tumours. Short mono- or dinucleotide repeats in the control region, such as (C)7, (A)5 or (CA)5, were not altered regardless of nuclear genetic instability. In summary, mtDNA is mutated in a subset of benign and malignant gastric tumours, but, disruption of the mtDNA repair system appears not to be significantly involved in gastric tumours of Japanese patients.

Abstract
OBJECTIVE To investigate biomechanical determinants and predictors of walking speed in early gait training after stroke. DESIGN Prospective. SETTING Physical therapy room of Tohoku University Hospital. PARTICIPANTS Thirty-four male hemiparetic stroke patients received 8 weeks of computer-assisted gait training (CAGT), which was initiated within approximately 3 months after stroke onset. MAIN OUTCOME MEASUREMENTS The time and the number of steps required to walk 10m at the fastest possible speed (maximum walking speed [MWS]), the sway path of the center of feet pressure (CFP) in the upright posture, the change in CFP when shifting the body weight either left to right or back and forth, and the maximal isokinetic muscle strength during extension of both knees were measured at the start and at 4 and 8 weeks. Stepwise regression procedures were performed to analyze determinants and predictors of the MWS using the MWS as the dependent variable and personal characteristics, standing balance, and the muscle strength of both knees as the independent variables. RESULTS The MWS significantly increased from 40.4 to 76.5m/min on average after 8 weeks. The determinant of MWS at the start was the postural control of shifting to the left and right (coefficient of determination of 45.4%). The determinant of MWS at 4 and 8 weeks was the muscle strength during knee extension on the affected side (coefficient of determination of 62.9% and 54.5%, respectively). The predictors of MWS at 4 weeks were the MWS at the start of CAGT, followed by muscle strength during knee extension on the affected side and the time from stroke onset to the start of CAGT (total variance of 84.3%). The predictors at 8 weeks were the MWS at the start, followed by the muscle strength during knee extension on the affected side (total variance of 73.4%). CONCLUSIONS After 4 weeks, the biomechanical determinant of MWS had changed from the postural control of weight-shifting from left to right to the muscle strength during knee extension on the affected side. The MWS at 4 and 8 weeks could be predicted by the initial MWS, the initial muscle strength during knee extension on the affected side, and the time since stroke onset, with high coefficients of determination.
