ABSTRACT

PURPOSE: This study aimed to synthesize and assess evidence on non-pharmacological interventions for older adults, including those with prefrailty and frailty. MATERIALS AND METHODS: A comprehensive review of randomized trials and cohort studies on non-pharmacological interventions for individuals aged ≥60 was conducted using MEDLINE, CENTRAL, and Web of Science through April 2023. RESULTS: Of the 285 papers screened, 13 met the eligibility criteria. Participants aged 62-98 years were studied across 42,917 individuals. Four systematic reviews (SR) focused on healthy older adults, seven on prefrailty, and eleven on frailty. Interventions included exercise therapy (7 articles), nutritional therapy (3 articles), exercise games (1 article), and combined exercise and nutritional therapy (2 articles). Non-pharmacological interventions showed improvement in frailty in 1 out of 1 SR and prevention of frailty progression in 3 out of 4 SRs. Improvements in physical function were noted in 9 out of 12 SRs, muscle strength in 8 out of 11, and muscle mass in 4 out of 6. Exercise interventions enhanced strength, mass, and function in older adults, including those with prefrailty or frailty, whether alone or combined with other components. Combined exercise and nutritional therapy were found to be more effective than monotherapy. Outcomes related to falls, cognitive function, and quality of life were controversial, and no positive effect on mortality was observed. CONCLUSIONS: Exercise therapy, including multicomponent interventions, can prevent frailty and improve physical function, strength, and muscle mass. Nutritional therapy has some advantages, but its combination with exercise therapy is recommended.

ABSTRACT

Objectives: There is a lack of evidence regarding the association between whole-body exercise and independence in urination and defecation. This study aimed to evaluate the effect of chair-stand exercise on improving urination and defecation independence in post-stroke patients with sarcopenia. Methods: A retrospective study was conducted on stroke patients admitted to a community rehabilitation hospital between 2015 and 2021. Patients diagnosed with sarcopenia who required assistance with bladder and bowel management were included. The primary outcomes were the Functional Independence Measure (FIM) scores for urination (FIM-Bladder) and defecation (FIM-Bowel) at discharge. Multiple regression analysis was used to examine the association between chair-stand exercise and the outcomes, adjusting for potential confounders. Results: Of 586 patients, 187 patients (mean age 79.3 years, 44.9% male) were included in the urination analysis, and 180 patients (mean age 79.3 years, 44.4% male) were included in the defecation analysis. Multiple regression analysis showed that the number of chair-stand exercises was independently positively associated with FIM-Bladder at discharge (ß=0.147, P=0.038) and FIM-Bladder gain (ß=0.168, P=0.038). Similarly, the number of chair-stand exercises was independently positively associated with FIM-Bowel at discharge (ß=0.149, P=0.049) and FIM-Bowel gain (ß=0.166, P=0.049). Conclusions: Chair-stand exercise was positively associated with improved urination and defecation independence in post-stroke patients with sarcopenia. Incorporating whole-body exercises, such as chair-stand exercise, in addition to conventional rehabilitation programs may help improve voiding independence, reduce incontinence, and enhance quality of life in these patients.

ABSTRACT

AIM: Addressing sarcopenia and frailty in aging populations is crucial for enhancing quality of life and reducing healthcare dependence. While the importance of energy, protein, and amino acid supplementation is known, the role of minerals needs further exploration. This systematic review evaluates the effectiveness of these minerals in managing sarcopenia and frailty. METHODS: We analyzed data from the Cochrane Central Register of Controlled Trials, MEDLINE, and Ichu-shi Web from January 2000 to March 2023. Studies were selected if they were interventional or observational, focused on individuals with frailty or sarcopenia who were aged 65 or older, and involved mineral supplementation. The risk of bias in these studies was assessed using the Cochrane Risk of Bias 2 tool. RESULTS: Of the 615 studies identified, seven met the inclusion criteria. These studies mainly focused on the effects of combined nutrient supplements, with few focusing on individual minerals. The findings were mixed, demonstrating some improvements in muscle strength, activity of daily living, and cognitive functions. Notably, minerals appeared to offer benefits as part of multi-nutrient interventions, especially for cognitive and immune health, but had limited impact on muscle mass or strength when used alone. The limited number and variable outcomes of studies precluded a feasible meta-analysis. CONCLUSIONS: The effect of mineral supplementation on sarcopenia and frailty remains uncertain, suggesting a need for tailored nutritional strategies. Future studies should aim for well-designed clinical trials in order to gain a better understanding of the roles of minerals in improving muscle health and functional outcomes, leading to clearer recommendations for clinical practice.

ABSTRACT

BACKGROUND AND AIMS: The triad approach combining rehabilitation, nutrition support, and oral management has garnered increasing interest for improving outcomes in older adults. However, evidence is limited regarding its effectiveness in post-stroke patients, who are at high risk for malnutrition, sarcopenia, oral problems, and dysphagia. This study aims to investigate the association between the triad approach and improvement in activities of daily living (ADL), muscle strength, and skeletal muscle mass in these patients. METHODS: A retrospective cohort study was conducted using post-stroke patients. Patients were divided into groups based on their exposure to the triad approach, defined as a combination of intensive chair-stand exercise (rehabilitation), personalized food prescriptions (nutrition support), and oral management by dental professionals. We investigated the association between the triad approach and outcomes using multiple linear regression analysis adjusted for covariates. Primary outcome was Functional Independence Measure motor score (FIM-motor) at discharge and its gain. Secondary outcomes were handgrip strength (HGS) and skeletal muscle mass index (SMI) at discharge. RESULTS: The study included 1012 post-stroke patients (median age 75.6 years; 54.1% men). Multiple linear regression analysis revealed that the triad approach had the strongest association with higher FIM-motor at discharge (ß = 0.262, p < 0.001) and FIM-motor gain (ß = 0.272, p < 0.001) compared to the individual or combined interventions. The triad also showed the strongest associations with higher HGS (ß = 0.090, p = 0.017) and SMI (ß = 0.041, p = 0.028) at discharge. CONCLUSIONS: The triad approach of intensive rehabilitation, personalized nutrition support, and oral management by dental professionals is strongly associated with improved ADL, muscle strength, and skeletal muscle mass in post-stroke rehabilitation patients. Implementing this multidisciplinary strategy may maximize functional and muscle health recovery.

ABSTRACT

AIM: Low body mass index (BMI) and poor oral health are prevalent among older stroke patients and associated with adverse outcomes. However, their combined impact on functional recovery after stroke remains unclear. This study investigated the synergistic effects of low BMI and poor oral health on activities of daily living (ADL) independence, swallowing function, and cognitive status in post-stroke older patients. METHODS: A retrospective cohort study was conducted on 708 hospitalized post-stroke patients aged ≥70 years. Low BMI was defined as <20 kg/m2, and poor oral health was assessed using the Revised Oral Assessment Guide (ROAG) with a score ≥13 indicating oral problems. The primary outcome was ADL independence (Functional Independence Measure-motor score >78) at discharge. Secondary outcomes included swallowing level (Food Intake Level Scale) and cognitive status (Functional Independence Measure-cognition score). Multiple regression analyses were performed to examine the associations of low BMI, poor oral health, and their combination with outcomes of interest. RESULTS: The coexistence of low BMI and poor oral health was independently associated with lower odds of achieving ADL independence (odds ratio 0.130, 95% confidence interval [CI] 0.023-0.718), worse swallowing level (B = -0.878, 95% CI -1.280 to -0.476), and poorer cognitive status (B = -1.872, 95% CI -2.960 to -0.784) at discharge, after adjusting for confounders. The combined impact was stronger than either condition alone. CONCLUSIONS: The coexistence of low BMI and poor oral health exerts a synergistic negative impact on functional recovery in older stroke inpatients. Comprehensive interventions integrating nutritional support, oral management, and rehabilitation are crucial to optimizing outcomes in this vulnerable population.

ABSTRACT

PURPOSE: Evidence is scarce on the associations between impaired oral health and cognitive level related to independence in activities of daily living (ADLs) among hospitalized older patients. We aimed to evaluate the associations between baseline oral problems and changes in cognitive level in post-stroke patients. METHODS: A retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients. Revised Oral Assessment Guide (ROAG) as a measure of oral health and function was assessed at admission. Primary outcomes included discharge scores for cognitive function assessed by the cognitive domain of the Functional Independence Measure (FIM-cognition) and the corresponding change in FIM-cognition during hospitalization. Another outcome measure was the motor domain of FIM (FIM-motor). Multivariate linear regression analyses were employed to assess the association between baseline ROAG and the designated outcomes, adjusting for potential confounding factors. RESULTS: Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median ROAG was 10 [9, 12], with 811 patients (84.9%) presenting oral problems. After fully adjusting for confounding factors, the ROAG was significantly and negatively associated with FIM-cognition at discharge (ß = -0.107, p = 0.031) and FIM-cognition gain (ß = -0.093, p = 0.018). Further, the ROAG was independently and negatively associated with FIM-motor at discharge (ß = -0.043, p = 0.013) and FIM-motor gain (ß = -0.065, p = 0.013). CONCLUSION: Oral problems were associated with compromised cognitive levels and a decline in physical function during the hospitalization in post-stroke patients. These results underscore the critical importance of addressing oral health in this patient population.

ABSTRACT

PURPOSE: Evidence is scarce regarding the association between anemia and alterations in cognitive level among hospitalized older patients. We aimed to evaluate the associations between baseline hemoglobin (Hb) levels and changes in cognitive level in patients undergoing rehabilitation after stroke. METHODS: A retrospective cohort study was conducted, encompassing consecutively hospitalized post-stroke patients. Data on serum Hb levels were extracted from medical records, specifically tests conducted within 24 hours of admission. Primary outcomes included discharge scores for cognitive function assessed by the cognitive domain of the Functional Independence Measure (FIM-cognition) and the corresponding change in FIM-cognition during hospitalization. Another outcome measure was the length of hospital stay. Multivariate linear regression analyses were employed to assess the association between Hb levels at admission and the designated outcomes, adjusting for potential confounding factors. RESULTS: Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median Hb level at admission was 13.3 [11.9, 14.5] g/dL. After fully adjusting for confounding factors, the baseline Hb level was significantly and positively associated with FIM-cognition at discharge (ß = 0.045, p = 0.025) and its gain (ß = 0.073, p = 0.025). Further, the baseline Hb level was independently and negatively associated with length of hospital stay (ß = -0.013, p = 0.026). CONCLUSION: Elevated baseline Hb levels are correlated with preserved cognitive level and shorter hospital stays in post-stroke patients. Evaluating anemia at the outset serves as a crucial prognostic indicator.

ABSTRACT

Objectives: Evidence is scarce regarding the association between hyponatremia and functional outcomes among older hospitalized patients. We aimed to evaluate the associations between baseline hyponatremia and improvement in activities of daily living (ADL) and muscle health in hospitalized post-stroke patients. Methods: This retrospective cohort study included hospitalized post-stroke patients. Serum sodium concentrations were extracted from medical records based on blood tests performed within 24 h of admission, with hyponatremia defined as a serum sodium concentration below135 mEq/L. Primary outcome was the discharge ADL as assessed by the motor domain of the Functional Independence Measure (FIM-motor) and its corresponding gain during hospitalization. Other outcomes encompassed the discharge scores for skeletal muscle mass (SMI) and handgrip strength (HGS). Multivariate linear regression analyses were used to determine the association between hyponatremia and outcomes of interest, adjusted for potential confounders. Results: Data from 955 patients (mean age 73.2 years; 53.6% men) were analyzed. The median baseline blood sodium level was 139 [interquartile range: 137, 141] mEq/L, and 84 patients (8.8%) exhibited hyponatremia. After full adjustment for confounders, baseline hyponatremia was significantly and negatively associated with FIM-motor at discharge (ß=-0.036, P=0.033) and its gain during hospital stay (ß=-0.051, P=0.033). Baseline hyponatremia exhibited an independent and negative association with discharge HGS (ß=-0.031, P=0.027), whereas no significant association was found between baseline hyponatremia and discharge SMI (ß=-0.015, P=0.244). Conclusions: Baseline hyponatremia demonstrated a correlation with compromised ADL and muscle health in individuals undergoing rehabilitation after stroke.

ABSTRACT

PURPOSE: Evidence is scarce regarding the association between hyponatremia and alterations in cognitive function among hospitalized older patients. We aimed to investigate the associations between hyponatremia and the baseline cognitive status, as well as the improvement in cognitive function, in hospitalized post-stroke patients. METHODS: This retrospective cohort study included consecutive hospitalized post-stroke patients. Serum sodium concentrations were extracted from medical records based on blood tests performed within 24 h of admission, with hyponatremia defined as a serum sodium concentration < 135 mEq/L. The main outcomes included admission and discharge scores for cognitive levels, assessed through the cognitive domain of the Functional Independence Measure (FIM-cognition), as well as the score changes observed during the hospitalization period. Multivariate linear regression analyses were used to determine the association between hyponatremia and outcomes of interest, adjusted for potential confounders. RESULTS: Data from 955 patients (mean age 73.2 years; 53.6 % men) were included in the analysis. The median baseline blood sodium level was 139 [137, 141], and 84 patients (8.8 %) exhibited hyponatremia. After full adjustment for confounders, the baseline hyponatremia was significantly and negatively associated with FIM-cognition values at admission (ß = -0.009, p = 0.016), discharge (ß = -0.038, p = 0.043), and the gain during hospital stay (ß = -0.040, p = 0.011). CONCLUSION: Baseline hyponatremia has demonstrated a correlation with decline in cognitive level over the course of rehabilitation in individuals after stroke. Assessing hyponatremia at the outset proves to be a pivotal prognostic indicator.

ABSTRACT

Background: Systemic inflammation is associated with poor functional outcomes. However, the effects of improved inflammation on functional indicators remain unclear. This study aimed to clarify the relationship between improvements in systemic inflammation and activities of daily living (ADL) in patients after stroke. Methods: This retrospective cohort study included patients post stroke with systemic inflammation upon admission. Systemic inflammation was defined as a modified Glasgow Prognostic Score (mGPS) score of 1-2. Improvement in systemic inflammation was defined as a reduction in mGPS score or blood C-reactive protein (CRP) levels during hospitalization. The primary outcomes were the motor items of the Functional Independence Measure (FIM-motor) at discharge. We applied multiple linear regression analysis to examine whether reduced systemic inflammation was associated with outcomes after adjusting for confounding factors. Results: Of the 1490 patients recruited, 158 (median age, 79 years; 88 men) had systemic inflammation on admission and were included in the study. Among these patients, 131 (82.9%) and 147 (93.0%) exhibited reduced mGPS and CRP levels, respectively. The median change in CRP was 2.1 [1.1, 3.8] mg/dL. Multivariate analysis revealed that improvements in mGPS (ß = 0.125, p = 0.012) and CRP levels (ß = 0.108, p = 0.108) were independently and positively associated with FIM-motor at discharge. Conclusions: Improvement in systemic inflammation was positively associated with functional outcomes in patients post stroke. Early detection and therapeutic intervention for systemic inflammation may further improve outcomes in these patients.

ABSTRACT

BACKGROUND: Anticholinergic burden is associated with adverse events in the older adults. However, there is a lack of evidence regarding its effect on urinary independence in stroke patients. AIM: This study examined the association between increased anticholinergic burden during hospitalization and urinary independence in post-stroke patients undergoing rehabilitation. METHOD: This observational cross-sectional study included stroke patients admitted to a post-acute rehabilitation hospital between 2020 and 2022 who were not independently urinating. The degree of urinary independence was assessed using the Functional Independence Measure-Bladder (FIM-Bladder), a subscale of the motor domain of the FIM, and urinary independence was defined as FIM-Bladder ≥ 6. Anticholinergic burden was assessed using the anticholinergic risk scale (ARS), and changes in ARS during hospitalization were calculated by subtracting the value at admission from the value at discharge. The study outcome was urinary independence at discharge. Logistic regression analysis was used to examine whether change in ARS score was independently associated with the outcome. Statistical significance was set at P < 0.05. RESULTS: Of the 573 patients enrolled, 312 patients (mean age 77.5 years, 51.9% male) were included in the analysis. ARS increased during hospitalization in 57 patients (18.3%). Change in ARS score was independently associated with urinary independence (odds ratio: 0.432, 95% confidence interval: 0.247-0.756, P = 0.003). CONCLUSION: Increased anticholinergic burden in post-stroke patients who require assistance with urination is significantly associated with less independent urination. Anticholinergic agents may need to be introduced cautiously in patients who require assistance with urination.

ABSTRACT

PURPOSE: Oral problems and muscle health are indeed significant concerns in ageing populations. However, there is limited evidence concerning the association between these issues. The study's focus was to investigate the association between oral problems and sarcopenic obesity, wherein sarcopenia and obesity coexist concurrently, in post-stroke patients. METHODS: This retrospective, observational, cross-sectional study included patients hospitalised for post-stroke rehabilitation. Oral problems were assessed using the Revised Oral Assessment Guide (ROAG). Sarcopenic obesity was diagnosed according to the European Society of Clinical Nutrition and Metabolism/European Association for the Study of Obesity criteria. Multiple linear regression analysis was used to examine the association between the ROAG and sarcopenic obesity after adjusting for confounding factors. RESULTS: A total of 760 patients were included, with a mean (SD) age of 71 (9) years, of whom 408 (54.7%) were male. The median (interquartile range, 25th and 75th percentiles) ROAG was 11 [9, 13]. Sarcopenic obesity was diagnosed in 16 (3.9%) men, 18 (5.1%) women, and 34 (4.5%) patients overall. Multivariate linear analysis showed that ROAG was significantly and positively associated with sarcopenic obesity (ß = .091, P = .023), followed by obesity alone (ß = .084, P = .044), and sarcopenia alone (ß = .081, P = .037). CONCLUSION: Oral problems were associated with sarcopenic obesity in post-stroke. Oral assessment and intervention may have a positive impact on ADL and QOL in post-stroke patients with sarcopenic obesity.

ABSTRACT

Objective: Sarcopenia negatively affects the short-term prognosis of hospitalized older adults. However, no evidence currently supports a direct relationship between sarcopenia and readmission among individuals who have experienced an acute stroke. Therefore, we investigated whether sarcopenia is associated with readmission after discharge. Methods: This retrospective cohort study included patients who had experienced acute stroke. Sarcopenia was defined as the coexistence of low skeletal muscle mass index (SMI) and grip strength. We applied the log-rank test and Cox proportional hazards regression analysis to analyze whether sarcopenia, low SMI, and low grip strength were associated with readmission within 6 months. Results: Among 228 included patients (mean age, 72.8 years; 146 males), the prevalence of sarcopenia was 24.6% (n=56; male, 17.8%; female, 36.6%). Cox proportional hazards regression analysis using the propensity score as a covariate revealed that sarcopenia (hazard ratio [HR] 7.21 [95% confidence interval (CI) 1.45-35.8]; p=0.016) and low skeletal muscle mass (HR 7.40 [95% CI 1.14-48.1; p=0.036), but not low grip strength (HR 1.42 [95% CI 0.281-7.21]; p=0.670), were significantly associated with readmission for stroke within 6 months. Conclusions: Sarcopenia was negatively associated with readmission within 6 months of stroke onset in patients in Japan who had experienced an acute stroke. These findings suggest that the identification of sarcopenia may facilitate prognostic prediction from the acute stage and intervention(s) to prevent rehospitalization.

ABSTRACT

BACKGROUND: This study aimed to determine whether changes in phase angle during rehabilitation are associated with clinical outcomes such as activities of daily living (ADL), skeletal muscle mass index (SMI), and strength in patients with osteoporotic fractures. METHODS: This retrospective observational study included patients with osteoporotic fractures admitted to convalescent rehabilitation wards. Changes in phase angle were defined as the difference between the phase angle values at discharge and on admission. The primary outcome was the Functional Independence Measure motor (FIM-motor) score at discharge. The secondary outcomes were SMI and handgrip strength at discharge. We used multivariate analysis to adjust for confounding factors and examine the association between changes in the phase angle and outcomes. RESULTS: We analyzed a total of 115 patients (97 women, mean age of 81.0±10.0 years), with a median change in phase angle of 0° during hospitalization. We observed increased phase angles in 49 patients (43%), with a median increase of 0.2°. Multiple regression analysis showed that changes in phase angle were independently associated with FIM-motor score at discharge (ß=0.238, p=0.027). Changes in phase angle were not significantly associated with SMI (ß=0.059, p=0.599) or handgrip strength (ß=-0.032, p=0.773) at discharge. CONCLUSION: An increased phase angle during rehabilitation was positively associated with ADL improvement in patients with osteoporotic fractures. These findings may help clinicians make informed decisions regarding patient care and treatment strategies for better outcomes.

ABSTRACT

Acute lung injury (ALI), which occurs in association with sepsis, trauma, and coronavirus disease 2019 (COVID-19), is a serious clinical condition with high mortality. Excessive platelet-leukocyte aggregate (PLA) formation promotes neutrophil extracellular trap (NET) release and thrombosis, which are involved in various diseases, including ALI. Macrophage-1 antigen (Mac-1, CD11b/CD18), which is expressed on the surface of leukocytes, is known to promote NET formation. This study aimed to elucidate the role of Mac-1 in extracellular histone-induced ALI. Exogenous histones were administered to Mac-1-deficient mice and wild-type (WT) mice with or without neutrophil or platelet depletion, and several parameters were investigated 1 h after histone injection. Depletion of neutrophils or platelets improved survival time and macroscopic and microscopic properties of lung tissues, and decreased platelet-leukocyte formation and plasma myeloperoxidase levels. These improvements were also observed in Mac-1-/- mice. NET formation in Mac-1-/- bone marrow neutrophils (BMNs) was significantly lower than that in WT BMNs. In conclusion, our findings suggest that Mac-1 is associated with exacerbation of histone-induced ALI and the promotion of NET formation in the presence of activated platelets.

ABSTRACT

AIM: There is limited evidence concerning the association between anemia and alterations in muscle health among hospitalized older patients. We aimed to evaluate the associations between baseline hemoglobin (Hb) levels and changes in muscle function in patients undergoing rehabilitation after stroke. METHODS: This retrospective cohort study included consecutive hospitalized post-stroke patients. Data on serum Hb level were extracted from medical records on tests performed within 24 h of admission. The main outcomes were discharge score for the skeletal muscle mass index (SMI) obtained through bioimpedance analysis and the corresponding change in SMI during hospitalization. Other outcomes were handgrip strength (HGS) at discharge and the alteration in HGS during hospitalization. Multivariate linear regression analyses were used to determine the association between Hb levels at admission and outcomes of interest, adjusted for potential confounders. RESULTS: Data from 955 patients (mean age 73.2 years; 53.6% men) were included in the analysis. The median Hb level at admission was 13.3 [11.9, 14.5] g/dL. After fully adjusting for confounding factors, the baseline Hb level was significantly and positively associated with SMI at discharge (ß = 0.046, P = 0.039) and with SMI gain (ß = 0.010, P = 0.039). Further, the baseline Hb level was independently and positively associated with HGS at discharge (ß = 0.058, P = 0.014) and with its change from baseline (ß = 0.100, P = 0.014). CONCLUSION: Diminished baseline Hb levels were demonstrated be correlated with compromised muscle health in patients after stroke. Evaluating anemia at the outset serves as a crucial prognostic indicator. Geriatr Gerontol Int 2024; 24: 305-311.

ABSTRACT

Objectives: The purpose of this study was to examine the association between baseline dysphagia and the improvement of activities of daily living performance and cognitive level among inpatients after stroke. Methods: This was a retrospective cohort study of patients undergoing convalescent rehabilitation after stroke. Dysphagia was assessed using the Food Intake LEVEL Scale. Outcomes were the motor and cognitive scores of the Functional Independence Measure (FIM) at discharge. Multiple regression analysis was performed to examine the association between dysphagia at admission and these outcomes. Results: There were 499 participants with a median age of 74 years. A multiple regression analysis was carried out after adjusting for potential confounders including age and sex. Dysphagia at admission was independently and negatively associated with motor (ß=-0.157, P<0.001) and cognitive (ß=-0.066, P=0.041) FIM scores at discharge. Conclusions: Baseline dysphagia in patients after stroke was negatively associated with improvement in performance of activities of daily living and cognitive level.

ABSTRACT

Objectives: This study aimed to determine whether the phase angle is associated with physical function at discharge and discharge destination in patients with osteoporotic fragile fractures. Methods: This retrospective cohort study included patients with fragile osteoporotic fractures who were admitted to a convalescent rehabilitation ward. The phase angle was calculated using a body composition meter and bioelectrical impedance analysis. The primary outcome was the Functional Independence Measure motor (FIM-motor) score at discharge, and the secondary outcome was discharge to home. Multivariate analysis was used to determine the association between phase angle and FIM-motor scores at discharge and discharge to home. Results: The study included 127 patients (108 women, age 81.2 ± 9.7 years). The median phase angle on admission was 4.1° for men and 3.6° for women. The median FIM-motor score at discharge was 83, with 92 (72.4%) patients discharged home and 35 (27.6%) discharged to a destination other than home. Multiple regression analysis adjusted for confounders revealed a significant independent association between the phase angle and FIM-motor score at discharge (ß=0.262, P=0.019). However, no significant association was found between phase angle and discharge destination (odds ratio, 1.350; 95% confidence interval: 0.680-2.670, P=0.391). Conclusions: Phase angle was independently associated with physical function at discharge in patients with fragile osteoporotic fractures. For patients with a reduced phase angle on admission, a multidisciplinary approach, including exercise, nutrition, oral health, and medication, should be implemented to maximize improvement in physical function.
