Predictive ability of hand-grip strength and muscle mass on functional prognosis in patients rehabilitating from stroke.

OBJECTIVES: This study aimed to investigate the association between muscle strength and adjusted appendicular skeletal muscle mass (ASM) in patients who have had strokes with the Functional Independence Measure (FIM) and the probability of being discharged. METHODS: A retrospective cohort study was conducted for older patients who have had strokes admitted to convalescent rehabilitation wards between January 2017 and October 2020. Hand-grip strength (HGS) was used to assess muscle strength. ASM was measured with a bioelectrical impedance analysis, and then divided by height-squared, body weight, body mass index (BMI), body fat mass (BFM), and body fat percentage (BFP) to calculate the adjusted ASM. The primary outcome was FIM at the time of discharge, and the secondary outcome was the probability of being discharged to their home. Multivariate analyses were conducted to adjust for confounding effects. RESULTS: The data of 699 participants (female: 47%; median age, 79 y) were analyzed. HGS was independently associated with FIM at the time of discharge in men (partial regression coefficient [B] = 0.482; 95% confidence interval [CI], 0.225-0.740) and women (B = 0.664; 95% CI, 0.263-1.065) and also was independently associated with being discharged to their home in men (odds ratio [OR]: 1.070; 95% CI, 1.030-1.100) and women (OR: 1.070; 95% CI, 1.000-1.130). Conversely, none of the adjusted ASM indices were associated with the outcomes. The cutoff value of HGS for discharge to home was 15.1 kg for men and 9.5 kg for women. CONCLUSIONS: In patients who have had strokes, HGS independently predicted FIM at the time of discharge and the probability of being discharged to their home. The adjusted ASM methods had less predictive value for functional and discharge outcomes.

Oishi K, Nishioka S, Okazaki Y, Hirakawa K, Nakamura M, Ichinose A, Kurihara M. Relationship between oral hygiene and function and activities of daily living at discharge in convalescent patients with stroke. Jpn J Compr Rehabil Sci 2022; 13: 17-25. Objective: This study was designed to examine the relationship between improvement in oral hygiene and function and activities of daily living (ADLs) at discharge in patients admitted to convalescent rehabilitation wards. Methods: Eligible criteria were patients with stroke with a score of 13 or higher (i.e., severe oral problems) on the Revised Oral Assessment Guide (ROAG) at admission. Age, gender, primary diseases, rehabilitation dose, dentist visits and denture status, Eichner classification, eating status at admission and discharge, and body mass index at admission were collected. The patients were classified into two groups: those with ROAG scores of less than 9 points at discharge (good ROAG group) and those with scores of 9 points or more (poor ROAG group), and Functional Independence Measure (FIM) gain and total FIM discharge scores were compared using univariate and multivariate analyses. Results: The good and poor ROAG groups comprised 126 and 366 patients, respectively. The good ROAG group had significantly higher total FIM score, FIM efficiency, and FIM gain at discharge than the poor ROAG group (112 vs. 82; P < 0.001). The ROAG scores at discharge were independently associated with FIM gain (partial regression coefficient = -9.889, 95% confidence interval = -13.499 to -6.279) and total FIM score at discharge. Conclusion: Improvement in oral hygiene and function in convalescent patients with stroke was associated with ADLs at hospital discharge.

Prevalence and Associated Factors of Coexistence of Malnutrition and Sarcopenia in Geriatric Rehabilitation.

Malnutrition and sarcopenia often coexist in rehabilitation patients, although they are often overlooked and undertreated in clinical practice. This cross-sectional study aimed to clarify the prevalence of the coexistence of malnutrition and sarcopenia (Co-MS) and its associated factors in convalescent rehabilitation wards in Japan. Consecutive patients aged ≥ 65 years in convalescent rehabilitation wards between November 2018 and October 2020 were included. Malnutrition and sarcopenia were determined by the Global Leadership Initiative on Malnutrition (GLIM) criteria and the Asian Working Group for Sarcopenia (AWGS 2019) criteria, respectively. Patients who presented both with malnutrition and sarcopenia were classified as Co-MS. Potentially associated factors included age, sex, days from onset to admission of rehabilitation wards, reason for admission, pre-morbid functional dependency, comorbidity, activities of daily living, swallowing ability, and oral function and hygiene. The prevalence of malnutrition, sarcopenia, and Co-MS was calculated. Binary logistic regression analyses were performed to compute odds ratios (ORs) and the 95% confidence interval (CI) of possible associated factors for each condition. Overall, 601 patients were eligible for the analysis (median 80 years old, 355 female patients, 70% cerebrovascular disease). Co-MS, malnutrition, and sarcopenia were found in 23.5%, 29.0%, and 62.4% of the enrolled patients, respectively. After adjustment, onset-admission interval (OR = 1.04; 95% CI = 1.02 to 1.06), hospital-associated deconditioning (OR = 4.62; 95% CI = 1.13 to 18.8), and swallowing ability (Food Intake LEVEL Scale) (OR = 0.83; 95% CI = 0.73 to 0.93) were identified as independent explanatory factors of Co-MS. In conclusion, Co-MS was prevalent in geriatric rehabilitation patients; thus, healthcare professionals should be aware of the associated factors to detect the geriatric rehabilitation patients who are at risk of both malnutrition and sarcopenia, and to provide appropriate treatments.

Effect of Improvement in Sarcopenia on Functional and Discharge Outcomes in Stroke Rehabilitation Patients.

This cross-sectional study investigated the proportion of patients' recovery from sarcopenia status and the relationship between improvement in sarcopenia (IS) and function and discharge outcome in hospitalized patients with stroke. This study included patients with stroke, aged 65 years or more, with a diagnosis of sarcopenia, who were admitted to a convalescent rehabilitation ward. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia 2019 criteria. Patients were divided according to the presence or absence of sarcopenia at discharge: IS group and non-improvement in sarcopenia (NIS) group. Among the 227 participants (mean age: 80.5 years; 125 females), 30% (69/227) of the patients were in the IS group, while 70% (158/227) were in the NIS group. The IS group showed a higher Functional Independence Measure (FIM) than the NIS group (median 112 vs. 101, p = 0.003). The results demonstrated that IS was independently associated with higher FIM (partial regression coefficient, 5.378; 95% confidence interval (CI), 0.709-10.047). The IS group had higher odds of home discharge than the NIS group (odds ratio, 2.560; 95% CI, 0.912-7.170). In conclusion, recovery from sarcopenia may be associated with better function in patients with stroke.

Impact of nutritional status, muscle mass and oral status on recovery of full oral intake among stroke patients receiving enteral nutrition: A retrospective cohort study.

AIM: To clarify the correlation between malnutrition, muscle mass and oral status, and swallowing function recovery in stroke patients receiving enteral nutrition. METHODS: Patients with stroke and dysphagia receiving any amount of enteral nutrition in rehabilitation wards from 2012 to 2016 were eligible for inclusion in this retrospective study. On admission, body composition by bioimpedance analysis, malnutrition confirmed by the European Society for Clinical Nutrition and Metabolism criteria, oral status, functional independence measure and demographic data were collected. Characteristics were compared between "oral intake alone" and "artificial nutrition" groups based on the discharge status. Kaplan-Meier methods and the Cox proportional hazards model were used to determine explanatory factors for the probability of full oral intake. RESULTS: Among 174 patients, 113 were analysed (55 women; median age, 77 years). Overall, 61% and 39% were classified as "oral intake alone" and "artificial nutrition," respectively. Days from onset to admission to rehabilitation wards and motor Functional Independence Measure were higher in the "oral intake alone" group. Kaplan-Meier analysis demonstrated that patients with lower muscle mass exhibited lower probability of full oral intake (P = .009). The Cox proportional hazards model suggested that lower muscle mass (hazard ratio, 0.493; 95% CI, 0.286-0.850) and poor oral hygiene (hazard ratio, 0.573; 95% CI, 0.333-0.987) were independently correlated with "oral intake alone" status. Malnutrition and other oral status are not related to achieving full oral intake. CONCLUSIONS: Skeletal muscle mass and oral hygiene are independently correlated with full oral intake among stroke patients receiving enteral nutrition during the rehabilitation phase.
