RESUMO
[Purpose] The simultaneous application of static stretching and neuromuscular electrical stimulation (NMES) to calf muscles may enhance physiological parameters in young and healthy individuals; however, the efficacy of this intervention and potential sex variation remain to be elucidated. The present study aimed to investigate these aspects. [Participants and Methods] Thirty healthy university students (15 males and 15 females) participated in this study. All participants simultaneously underwent static stretching and NMES of the calf muscles for 4â min while lying on an upright and tilted table. The mean differences in the dorsiflexion angle (DFA), finger-floor distance (FFD), and straight leg raising (SLR) angle before and after the intervention were calculated. Sex variations were assessed using a two-way analysis of variance (ANOVA). [Results] The DFA, FFD, and SLR angle exhibited significant effects on time. No significant sex variations were observed between the groups. [Conclusion] Simultaneous static stretching and NMES of the calf muscles potentially enhanced the DFA, FFD, and SLR angle in healthy university students, irrespective of sex.
RESUMO
[Purpose] This study aimed to determine the characteristics of regional phase angles based on locomotion level among older Japanese females requiring long-term care in a health facility. [Participants and Methods] This was a cross-sectional observational study. The participants included 91 residents (mean age ± standard deviation: 90.2 ± 5.6â years) admitted to an older health facility. Based on their indoor locomotion status, the participants were divided into three groups: group I, able to walk with or without walking aids; group II, able to move in a wheelchair without assistance; and group III, able to move in a wheelchair with assistance. The regional phase angle was measured using a bioimpedance device. [Results] Significant differences were observed in the regional phase angle of the upper limbs between groups I and III and between groups II and III; in that of the lower limbs among all groups; and in that of the trunk between groups I and II and between groups I and III. [Conclusion] The level of locomotion may be explained by the regional phase angles of the lower limbs.
RESUMO
In the lives of those who are the target of community health nursing, it is important to collaborate with individuals and communities to improve their quality of life. Herein, we aimed to determine the association between Internet use among older individuals and locomotive syndrome (LS), frailty, and sarcopenia. In this cross-sectional study conducted between July 2022 and March 2023, we recruited 105 community-dwelling older Japanese adults who participated in a care prevention project called "Kayoi-no-ba". All participants were divided into Internet and non-Internet user groups according to the classification of a previous study. We assessed LS (standing test, two-step test, and five-question Geriatric Locomotive Function Scale), frailty (through the Questionnaire for Medical Checkup of Old-Old), and sarcopenia (grip strength, normal walking speed, and skeletal muscle mass index) and made group comparisons between Internet users and non-users. Binomial logistic regression analyses were performed with Internet use as the independent variable and sarcopenia or LS as the dependent variables. The Internet and non-Internet user groups had 69 and 36 participants, respectively. The Internet user group comprised 65.7% of all participants, which was similar to that reported in a previous study of the same age group. Between-group comparisons showed significant differences in sarcopenia and LS items, whereas adjusted binomial logistic analysis showed a significant association between sarcopenia and Internet use. In summary, among LS, frailty, and sarcopenia, sarcopenia showed the highest association with Internet use. Older adults without sarcopenia having good physical functions, such as grip strength, walking speed, and skeletal muscle index, more likely used the Internet; while older adults with sarcopenia were less likely to use the Internet. This implied that Internet use may be associated with physical function.
RESUMO
Background: In Japan, the number of older adults requiring long-term care insurance (LTCI) is increasing and the cost is becoming a social problem. In these fields, the role of geriatric rehabilitation includes maintaining the physical function and LTCI certification levels. The prevalence of sarcopenia is high among older adults requiring LTCI certification, and there are many opportunities to assess the handgrip strength, walking speed, and muscle mass. This study aimed to identify sarcopenia-related assessments sensitive to transitions in LTCI certification levels and determine cut-off values to predict them. Methods: This prospective cohort study analyzed 98 daycare users (mean age ± standard error: 78.5 ± 0.8 years) between March 2019 and 2023. The participants received LTCI certification before the study, and their levels were renewed between baseline and follow-up (six months later). The measurements included handgrip strength, usual walking speed, body composition, and SARC-F score. Participants were classified into maintenance, deterioration, and improvement groups according to the changes in their LTCI certification levels. We identified factors contributing to the deterioration of LTCI certification levels using baseline and before and after comparisons, multivariate analyses, and receiver operating characteristic analyses. Results: No significant differences were observed in the baseline data among the groups. Only the deterioration group showed significant changes in the usual walking speed (baseline: 0.64 ± 0.25 m/s, follow-up: 0.53 ± 0.21 m/s, P = 0.008) and body fat percentage (baseline: 29.2 ± 9.9%, follow-up: 27.7 ± 10.3%, P = 0.047). Binomial logistic regression showed that changes in usual walking speed (P = 0.042) and body fat percentage (P = 0.011) were significantly associated with the deterioration of LTCI certification levels, even after adjustment. The cutoff values of change to discriminate the deterioration of LTCI certification levels were -0.14 m/s at the usual walking speed (P = 0.047) and -1.0% for body fat percentage (P = 0.029). Conclusions: Decreases in usual walking speed and body fat percentage may predict worse certification levels in older adults requiring LTCI.

[Purpose] This study aimed to determine the association between calf and neck circumferences and skeletal muscle indices, including phase angle, among Japanese nursing home residents. [Participants and Methods] A cross-sectional study of a single nursing home was conducted, in which 72 nursing home residents (aged 85.9 ± 8.4â years, mean ± standard deviation [SD]) were enrolled. Calf and neck circumferences were measured using a measuring tape, and body composition assessment was measured using a bioimpedance device. [Results] The age- and sex-adjusted partial correlation coefficient showed that calf circumference exhibited a significantly high correlation with all body composition parameters; however, neck circumference exhibited a significantly low correlation with body fat percentage only. The calf circumference had a higher correlation coefficient than the neck circumference with all body composition items, except for body fat percentage. [Conclusion] This study showed that phase angle and muscle mass were associated with calf circumference, but not with neck circumference, in Japanese nursing home residents. Therefore, calf circumference is important in clinical evaluations as a potential screening tool for nursing home residents with various diseases.
RESUMO
[Purpose] This study aimed to identify the factors and cutoffs associated with walking independence in patients with severe COVID-19 pneumonia. [Participants and Methods] In total, 112 patients with COVID-19 pneumonia (98 males and 14 females) who were hospitalized between March 2020 and August 2021 and underwent physiotherapy during mechanical ventilation were included in the study. Attributes, respiratory function, physical function, and bed-withdrawal status were compared between two groups of patients, who were classified according to their ability to walk independently at discharge. The independent variables were reduced to four components by principal component analysis. Logistic regression analysis was performed with walking independence at discharge as the dependent variable. Receiver operating characteristic curves for the extracted factors were drawn, and cutoff values were calculated. [Results] At discharge, 76 patients were able to walk independently, while 36 were not. The logistic regression analysis was adjusted according to age and mechanical ventilation time. Cutoffs were an age of 56â years and a ventilation period of 7.5 days. [Conclusion] In cases of patients with severe COVID-19 pneumonia who required ventilators, age and mechanical ventilation time were associated with ambulatory independence at discharge, indicating the importance of reducing the ventilation period by providing respiratory physiotherapy, including expectoration, positioning, and weaning.
RESUMO
OBJECTIVE: The objective of the study was to evaluate visual outcomes between medical treatment alone (MED) and Ahmed glaucoma valve implantation (AGVI) in Shiba dogs with primary angle closure glaucoma (PACG). PROCEDURES: Records of 65 Shiba dogs (104 eyes) with PACG were retrospectively reviewed. Vision was assessed qualitatively using both the menace response and maze testing. The significance of age, sex, intraocular pressure (IOP), and duration of clinical signs (≤72 h or >72 h) at first presentation (V1) was assessed. Eyes with vision at V1 were divided into groups according to subsequent treatment method (MED versus AGVI), and vision as a survival outcome was compared between group by the Kaplan-Meier method. RESULTS: At V1, 65 eyes (62.5%) of 54 dogs had vision. There was no statistically significant difference in age or sex on the presence of vision at V1. Median IOP was higher in blind (52 mmHg) compared to sighted eyes (28 mmHg) (p < .001). Eyes presenting in ≤72 h of the onset of clinical signs were more likely to have vision (86.7%) compared to those presenting after 72 h (44.1%) (p < .001). By the Kaplan-Meier analysis, the cumulative visual retention rate was significantly higher with AGVI than with MED (69.2% vs. 7.7%; p < .01) at 12 months. The median time to visual loss was 39.9 months with AGVI vs. 1.7 months with MED. CONCLUSIONS: AGVI resulted in better visual outcomes than MED and should be considered in Shiba dogs with PACG that are visual at the time of presentation and suitable for surgery.
RESUMO
BACKGROUND: Elastic taping that applies shear force affects joint movement. However, it remains uncertain whether elastic taping or stretching is more effective in improving flexibility. OBJECTIVE: We investigated whether elastic taping for flexibility improvement is comparable to traditional stretching. METHODS: In this randomized controlled trial, 64 university students were randomly allocated to two groups: elastic taping on the sole or 30 s of static stretching. The primary outcome measures were the straight leg raising angle, tested with an equivalence margin (± 9.61∘ on changes), and the fingertip-to-floor distance. Secondary outcomes were the hip flexor and knee extensor strength, two-step distance, adverse events, and pain intensity during the intervention, which were compared using conventional statistical methods. RESULTS: The mean differences in straight leg raising between the two groups after the interventions were not greater than the equivalence margin (mean [95% CI]: 1.4 [-6.9, 9.5]; equivalence margin, -9.61∘ to 9.61∘). There were no consistent differences between groups in terms of secondary outcomes except for pain intensity during the intervention (p> 0.05). Elastic taping did not induce pain. CONCLUSION: Elastic taping augments the flexibility-improving effect comparable to static stretching, based on an equivalence margin. Elastic taping of the sole appears to be an alternative method of improving flexibility.

AIM: This study aimed to ascertain the prevalence of frailty during the pandemic and to determine factors associated with changes in frailty status. METHODS: In May-June of 2020-2022, we assessed the frailty of 549 participants using the Kihon Checklist. Furthermore, we classified participant residences as urban, suburban, and rural and investigated participants' engagement in hobbies and community activities in 2020 and 2022. Cochran's Q test was used to analyze the proportions of frailty status. Subsequently, we conducted a binomial logistic regression analysis with the improvement/deterioration of frailty status from 2020 to 2022 as the dependent variable, and engagement in hobbies and community activities as the independent variables. RESULTS: Significant changes were observed among participants in urban areas, where an increase in pre-frailty and a decrease in robust individuals from 2020 to 2021 were noted. Focusing on item no. 17 (going out), the decreasing frequency had recovered by 2022 in the group of all groups. Continued engagement in only hobbies or only community activities, and continued engagement in both were associated with remained robust/frailty-status improvement. Moreover, not engaging in either hobbies or community activities was associated with remained frail/frailty-status deterioration. CONCLUSIONS: During the early stages, the COVID-19 pandemic impacted the frailty of older adults in densely populated areas. The results also suggest an attenuation in the decline in older adult activity in 2022. Continuous engagement in hobbies and community activities was crucial for improving and preventing deterioration in frailty status during the COVID-19 pandemic. Geriatr Gerontol Int 2024; 24: 40-47.

[Purpose] The purpose of this study was to investigate the interrelationship between different baseline functional capacity items, and their relationship with postoperative course in colorectal cancer patients. [Participants and Methods] This was a three-institution cohort study that included 127 patients scheduled for elective colorectal cancer surgery. Baseline functional capacity was evaluated using skeletal muscle index (SMI), six-minute walk test (6MWT), serum-albumin (Alb), vitality, and mental health before surgery. Postoperative findings, including C-reactive protein (CRP) levels 3 days post-operation, frequency of postoperative complications, and length of hospital stay (LOS), were evaluated based on the medical records. [Results] CRP was positively related to SMI, but negatively related to Alb level. LOS was negatively related to vitality. The 6MWT results and mental health-related findings were not significantly related to the postoperative course, but were directly and indirectly related to vitality, respectively. Alb level was also indirectly related to vitality through the 6MWT and mental health-related findings. The final constructed model demonstrated an acceptable fit to the data (goodness-of-fit index=0.958, adjusted goodness-of-fit index=0.930, comparative fit index=1.000, root mean square error of approximation=0.000). [Conclusion] Nutrition status, as measured by Alb level before surgery, may positively affect both the postoperative course and other functional capacity parameters.
RESUMO
[Purpose] This study aimed to examine and compare the prevalence of frailty in 75 year-old people sampled in two remote years, namely 2006 and 2019. [Participants and Methods] A total of 910 participants aged 75â years were included (502 people in 2006 and 408 people in 2019). We compared the total score of the Kihon checklist and each question for males and females between the two years. [Results] The prevalence of frailty decreased from 24.3% in 2006 to 15.2% in 2019. The comparison of the 2006 and 2019 Kihon checklists revealed significant differences in activities of daily living, physical function, oral function, outdoor activities, and cognitive function. [Conclusion] Frailty among 75â year-old individuals improved in 2019 compared to that in 2006. Improved activities of daily living, physical function, outdoor activities, and cognitive function were major causes of improved frailty in 2019.
RESUMO
[Purpose] The present study aimed to investigate the association of phase angle with the continuing activities of residents in a geriatric health service facility for one year. We compared the phase angle among current residents in a geriatric health service facility with those who died within one year. [Participants and Methods] This one-year prospective observational study included 149 residents who entered a geriatric health service facility. We divided participants into two groups: an over one-year survival group and a death within one year group. The receiver operating characteristic curves were created to determine the sensitivity and specificity for predicting one-year mortality based on the phase angle. [Results] The phase angle was significantly higher in the one-year survival group than in the death within one year group and was independently and significantly associated with one-year mortality using binomial logistic regression analysis. The phase angle was shown to have predictive power (based on the area under the receiver operating characteristic curve). Based on the calculation for identifying one-year survival, the optimal cut-off value for the phase angle was 2.95° (area under the receiver operating characteristic curve=0.76, sensitivity 55.6%, specificity 83.3%). [Conclusion] The phase angle may contribute to the prognosis of one-year mortality for residents of geriatric health service facilities.
RESUMO
Background: Recently, metabolic dysfunction-associated fatty liver disease (MAFLD), which is based on evidence of hepatic steatosis and any of the following three conditions: overweight/obesity, presence of type 2 diabetes mellitus, or evidence of metabolic dysregulation, has been proposed. It is uncertain how indices that predict insulin resistance (IR) are associated with MAFLD. Methods: Among subjects who had undergone health examinations at our hospital, 1,257 (787 men and 474 women) who underwent fatty liver evaluation, were included in this cross-sectional study. The discriminatory ability of each index for MAFLD was tested using a receiver operating characteristic curve analysis. The associations between the homeostasis model assessment-IR (HOMA-IR), triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, triglyceride-glucose (TyG) index, and MAFLD were investigated using multiple logistic regression analysis. Results: The mean age and body mass index of MAFLD subjects were 58.1 years and 26.0 kg/m2 in men and 63.0 years and 26.1 kg/m2 in women, respectively. The cutoff values of HOMA-IR, TG/HDL-C ratio, and TyG index in men and women were 1.40 (area under the curve [AUC]: 0.81) and 1.90 (AUC: 0.88); 1.56 (AUC: 0.75) and 1.06 (AUC: 0.78); and 8.62 (AUC: 0.75) and 8.45 (AUC: 0.80), respectively. All indices were significantly higher in both men and women with MAFLD. In the multivariate models, the odds of MAFLD were higher among both men and women in the highest tertile than those in the lowest tertile. When subjects were divided by sex, presence of MAFLD, and alanine aminotransferase (ALT) values, all indices were significantly higher in both men and women with high ALT levels who were diagnosed with MAFLD. Conclusion: IR strongly correlated with MAFLD, particularly in subjects with high ALT levels.

[Purpose] In this study, we investigated the effectiveness of elastic tape in increasing the dorsiflexion angle and plantar flexor strength in healthy individuals. [Participants and Methods] This randomized controlled trial included 24 healthy university students who were categorized into the following groups (12 participants in each group): the intervention group (elastic tape was applied to the dominant foot) and the control group (no intervention was performed). We performed intergroup comparison of the pre- and post-intervention dorsiflexion angles and plantar flexor strength. Additionally, we performed subgroup analyses based on a straight-leg raise angle of 70°. [Results] We observed no significant intergroup differences in the dorsiflexion angle or plantar flexor strength. However, the post-intervention dorsiflexion angle was significantly greater than the pre-intervention angle in the subgroup with a straight-leg raise angle of <70° among participants in the elastic tape group. [Conclusion] Elastic tape application may effectively increase the dorsiflexion angle in individuals without hamstring extensibility.
RESUMO
Background and objectives: The combination of depression and sarcopenia, a condition prevalent worldwide, may cause dis-tinct problems that should not be underestimated. However, to the best of our knowledge, no reports have investigated the combined effects of depression and sarcopenia. In this study, we compared physical function, nutritional status, and daily functioning among older adults with only depression (OD), those with only sarcopenia (OS), and those with sarcopenia with depression (SD) to examine the effects of the combination of depression and sarcopenia. Materials and Methods: The participants were 186 communi-ty-dwelling older individuals who required support or care. The participants were classified into four groups based on the presence or absence of sarcopenia and depression: Control, OD, OS, and SD. The following parameters were evaluated in the four groups: grip strength, walking speed, skeletal muscle mass index (SMI), Mini Nutritional Assessment Short-Form (MNA-sf), and long-term care certification level. In addition, univariate and multivariate analyses of the survey results were performed to identify risk factors leading from OS to SD. Results: We found that 31.2% of older participants who needed support or nursing care had SD, which had more pronounced adverse effects on grip strength, walking speed, SMI, MNA-sf, and level of nursing care than OD or OS. Furthermore, multivariate analysis of SD vs. OS showed that decreased grip strength and worsening MNA-sf were independent risk factors. Conclusions: SD is common among older individuals living in the community. Patients with SD require support and care, and the condition has a greater impact on physical function, nutritional status, and decline in life function compared to OD and OS. Therefore, it is desirable to elucidate the process leading to SD and investigate the risk factors and prognosis. It is expected that sarcopenia with depression will be investigated worldwide in the future.

[Purpose] Behavioral restrictions during the corona virus disease 2019 (COVID-19) pandemic may have affected the physical activity levels of college students. We aimed to characterize the body composition and physical activity of college students during these behavioral restrictions. [Participants and Methods] The body composition (height, weight, body mass index, body fat mass, body fat percentage, total body muscle mass, free-fat muscle index [FFMI], and fat mass index [FMI]), physical activity, amount the of walking, amount of daily activity, and the number of steps were measured in 52 university students. [Results] For both male and females, the number of steps taken was lower than the average steps reported by the Ministry of Health, Labour and Welfare. In males, FFMI had a strong positive correlation with physical activity, amount of walking, and the number of steps taken. In females, FFMI had a strong positive correlation with physical activity and the amount of walking, as well as a moderate positive correlation with the amount of daily activity. [Conclusion] Since physical activity and walking of university students during COVID-19 affect FFMI, it is necessary to develop an exercise program that considers behavioral patterns.
RESUMO
PURPOSE: This study investigated the impact of surgical treatment on the health-related quality of life (HRQOL) of Japanese patients with colorectal cancer (CRC). METHODS: This three-institution cohort study included 106 Japanese patients with CRC (69 men; mean age: 62.6 ± 12.4 years; age range = 30-85 years). HRQOL was evaluated using the Short-Form 36-Item Health Survey version 2 one to two days prior to surgery (baseline) and four weeks after surgery. Clinical characteristics, social characteristics, and HRQOL at baseline were investigated. RESULTS: Physical functioning, role-physical, bodily pain, and social functioning decreased significantly at four weeks after surgery compared with baseline, whereas mental health significantly improved. Physical functioning and general health perception showed an especially strong relation with the six-minute walk test (6MWT) at four weeks after surgery and HRQOL scores at baseline. The cutoff value for the 6MWT for clinically relevant improvement was 552.5 meters for physical functioning (area under curve [AUC] = 0.780, 95% confidence interval [CI] = 0.692-0.867) and 480.3 meters for general health perception (AUC = 0.721, 95% CI = 0.626-0.817). CONCLUSION: Patients with CRC could potentially improve their postoperative HRQOL by increasing their walking capacity post-surgery, and they may need follow-up interventions after discharge such as physical rehabilitation to do so. The results provide a potential pathway for improving HRQOL of Japanese patients with CRC.
