Development of two Barthel Index-based Supplementary Scales for patients with stroke

Reablement of Instrumental Activities of Daily Living for Patients With Stroke: A Randomized Crossover Trial

IMPORTANCE

Reablement is a person-centered and goal-oriented rehabilitative intervention to optimize people's chances to live independently.

OBJECTIVE

To investigate the effects of a reablement intervention on performance of instrumental activities of daily living (IADLs) in three aspects (i.e., actual performance, ability, and self-perceived difficulty) for patients with stroke.

DESIGN

A single-blinded, randomized crossover study.

SETTING

Participants' home and community.

PARTICIPANTS

Twenty-seven patients with stroke.

INTERVENTIONS

Each participant received two interventions (IADL reablement and health education). Each intervention was administered for 6 wk. All participants were randomly assigned to one intervention and then received the other intervention after a 4-wk washout period.

OUTCOMES AND MEASURES

Outcomes of actual performance and self-perceived difficulty were derived from the Frenchay Activities Index (FAI) and the difficulty dimension of the Participation Measure-3 Domains, 4 Dimensions (PM-3D4D), respectively. Outcomes of ability were measured with the Lawton Instrumental Activities of Daily Living Scale (LIADL) and the Canadian Occupational Performance Measure Performance score (COPM Performance).

RESULTS

No statistically significant differences were found in the three aspects between the IADL reablement and health education (ps = .148-.570). Compared with the health education, the IADL reablement showed better improvements on the FAI, LIADL, COPM Performance, and difficulty dimension of the PM-3D4D with trivial to small effect sizes (ds = 0.17-0.45).

CONCLUSIONS AND RELEVANCE

Our results reveal that the IADL reablement has the potential to increase the frequency of IADL administration, enhancing the capability to perform IADLs and reducing the self-perceived difficulty of carrying out IADLs. Plain-Language Summary: The results of this study showed positive outcomes for a reablement intervention that focuses on goal-oriented instrumental activities of daily living for patients with stroke. An IADL reablement intervention may be useful for improving the ability to carry out IADL tasks at home and in the community.

Inclusion of frailty improved performance of delirium prediction for elderly patients in the cardiac intensive care unit (D-FRAIL): A prospective derivation and external validation study

BACKGROUND

The elderly patients admitted to cardiac intensive care unit (CICU) are at relatively high risk for developing delirium. A simple and reliable predictive model can benefit them from early recognition of delirium followed by timely and appropriate preventive strategies.

OBJECTIVE

To explore the role of frailty in delirium prediction and develop and validate a delirium predictive model including frailty for elderly patients in CICU.

DESIGN

A prospective, observational cohort study.

SETTINGS

CICU at China-Japan Friendship Hospital from March 1, 2022 to August 25, 2022 (derivation cohort); CICU at Beijing Anzhen Hospital affiliated to Capital Medical University from March 14, 2023 to May 8, 2023 (external validation cohort).

PARTICIPANTS

A total of 236 and 90 participants were enrolled in the derivation and external validation cohorts, respectively. Participants in the derivation cohort were assigned into either the delirium (n = 70) or non-delirium group (n = 166) based on the occurrence of delirium.

METHODS

The simplified Chinese version of the Confusion Assessment Method for the Diagnosis of Delirium in the Intensive Care Unit was used to assess delirium twice a day at 8:00-10:00 and 18:00-20:00 until the onset of delirium or discharge from the CICU. Frailty was assessed using the FRAIL scale during the first 24 h in the CICU. Other possible risk factors were collected prospectively through patient interviews and medical records review. After processing missing data via multiple imputations, univariate analysis and bootstrapped forward stepwise logistic regression were performed to select optimal predictors and develop the models. The models were internally validated using bootstrapping and evaluated comprehensively via discrimination, calibration, and clinical utility in both the derivation and external validation cohorts.

RESULTS

The study developed D-FRAIL predictive model using FRAIL score, hearing impairment, Acute Physiology and Chronic Health Evaluation-II score, and fibrinogen. The area under the receiver operating characteristic curve (AUC) was 0.937 (95% confidence interval [CI]: 0.907-0.967) and 0.889 (95%CI: 0.840-0.938) even after bootstrapping in the derivation cohort. Inclusion of frailty was demonstrated to improve the model performance greatly with the AUC increased from 0.851 to 0.937 (p < 0.001). In the external validation cohort, the AUC of D-FRAIL model was 0.866 (95%CI: 0.782-0.907). Calibration plots and decision curve analysis suggested good calibration and clinical utility of the D-FRAIL model in both the derivation and external validation cohorts.

CONCLUSIONS

For elderly patients in the CICU, FRAIL score is an independent delirium predictor and the D-FRAIL model demonstrates superior performance in predicting delirium.

Assessment of Changes in Serum C-Reactive Protein Levels in Patients after Ischemic Stroke Undergoing Rehabilitation-A Retrospective Observational Study

Inflammation plays a key role in the pathogenesis and prognosis of ischemic stroke. C-reactive protein (CRP) is an inflammatory biomarker of inflammation and may reflect the progression of vascular disease. Using a biomarker such as CRP to predict recovery rather than mortality may present clinical value in providing rehabilitation. The primary aim of the study was to analyze changes in serum CRP levels in patients after ischemic stroke during the regenerative-compensatory period and to assess the usefulness of CRP as a potential biomarker during the rehabilitation period. The project was carried out as a retrospective analysis of prospectively collected data from post-stroke patients from the Department of Neurological Rehabilitation of the Regional Specialist Hospital in Wrocław. A group of 52 patients, after their first-ever ischemic stroke with subsequent hemiplegia, was finally qualified to participate in the study. Serum CRP levels were determined during blood laboratory tests. The Modified Rankin Scale (mRS) and Barthel Index (BI) were used to assess functional outcomes. Rehabilitation using neurophysiological methods was applied five days a week (each session lasted 60 min, and the entire period was 42 days). At the first test, serum CRP levels were found to be above 5 mg/L in 19 patients, the second test in 12 patients, the third test in five patients, and the fourth test in 9 patients. Only three patients had values higher than 5 mg/L in all consecutive assessments (p > 0.05). There was a statistically significant increase in BI scores after therapy (p < 0.001) as well as a decrease in the mRS score by 2.2 points (p < 0.001), in CRP values by 5.02 mg/L (p = 0.019), and in cortisol levels by 2.5 nmol/L (p = 0.002). Statistically significant relationships were observed between the CRP levels after rehabilitation and the corresponding mRS scores (rs = 0.29, p = 0.038). Furthermore, the effect of BMI on CRP levels was demonstrated (B = 0.20, p = 0.038). In conclusion, despite demonstrating a significant relationship between CRP levels and corresponding mRS scores, CRP levels alone may not serve as an independent predictor of long-term functional outcomes in ischemic stroke patients undergoing rehabilitation.

Short versions of the Geriatric Depression Scale (GDS) among widowed older people in Taiwan: Comparing their psychometric properties

OBJECTIVE

To compare the psychometric properties of different short versions of the Geriatric Depression Scale (GDS) among community-dwelling widowed older people.

METHODS

A cross-sectional design was conducted between February 2018 and August 2019 in southern Taiwan (n = 330). The GDS short versions included Hoyl et al's 5-item version, Molloy et al's 5-item version and van Marwijk et al's 4-item version.

RESULTS

All GDS short versions had satisfactory internal consistency (α = 0.83-0.90), with strong item loading embedded in the same construct of depression (0.43-0.72). The activity of daily living (ADL) scores had strong associations with van Marwijk et al's 4-item version (absolute standardised coefficient [|β|] = 0.15-0.59), Hoyl et al's 5-item version (|β| = 0.16-0.45) and Molloy et al's 4-item version (|β| = 0.09-0.40).

CONCLUSIONS

Hoyl et al's 5-item version was found to be more suitable than the other two versions of the GDS to assess the precise construct of depression. Meanwhile, van Marwijk et al's 4-item version can be used when the focus is on ADL performance. However, the conclusion should be interpreted with caution since the results were derived only from a widowed population in Taiwan. More research on this topic among other populations is thus needed to corroborate our conclusion.

Effect of home-based reablement program on improving activities of daily living for patients with stroke: A pilot study

BACKGROUND

Administering activities of daily living (ADL) and recovery of ADL functions are the main treatment goals in rehabilitation for patients with stroke. Reablement is one form of rehabilitative intervention, which aims to restore ADL functions performed in the community. The purpose of this study was to investigate the effects of home-based reablement from 3 concepts of ADL (ie, actual performance, ability, and self-perceived difficulty) for patients with stroke.

METHODS

This was a single-blind pilot randomized clinical trial. Twenty-six patients were randomly assigned into 2 groups: home-based reablement group (n = 12) and control group (n = 14). The home-based reablement group received ADL training in the home environment for 6 weeks. The control group received conventional rehabilitation in the hospital. Outcome measures contained the Canadian Occupational Performance Measure (COPM) and the Barthel Index-based Supplementary Scales (BI-SS). The COPM was applied to identify patients' level of performance and satisfaction with ADL training. The BI-SS included 3 ADL scales: actual performance, ability, and self-perceived difficulty.

RESULTS

The patients in the home-based reablement group showed statistically significant improvements in the ability scale and total score of the BI-SS than the control group (P < .05) and demonstrated moderate effect size (success rate difference = 0.34-0.42). No significant differences were noticed in the COPM and the other 2 scales of the BI-SS (actual performance and self-perceived difficulty), but small effect sizes were found (success rate difference = 0.17-0.22).

CONCLUSIONS

For patients with stroke, the 6-week home-based reablement program had similar effects with the control group on patients' perceived performance, satisfaction, and difficulty in ADL, but it displayed potential for enhancing their ability in executing ADL tasks.

An investigation and analysis of the activities of daily living of older adults living at home in Ningxia Hui Autonomous Region of China: a cross-sectional study

Background

To investigate the current situation regarding the activities of daily living (ADL) of older adults living at home in Ningxia Hui Autonomous Region of China and to analyze the associated factors of ADL performance so that we can provide references for the implementation of pension policies and long-term care insurance of older adults living at home.

Methods

We surveyed a total of 1040 older adults who live at home and receive home-based care in Ningxia Hui Autonomous Region by a face-to-face evaluation. A logistic regression model was used to analyze the factors associated with ADL performance.

Results

In the study, 82.79% of the older adults living at home can live independently. A total of 11.92% of the older adults have mild dysfunction, 4.33% have moderate dysfunction, and 0.96% have severe dysfunction. Multiple logistic analyses indicated that older adults with very difficult economic conditions (OR 3.212; 95% CI(1.209–8.534)) and without a spouse (OR 1.616; 95% CI(1.098–2.377)) were significantly associated with ADL limitations. In addition, the risks of ADL limitations in older adults aged 60–69 years and 70–79 years were 0.187 and 0.4307 times, respectively, that of older adults over 80 years old. The risk of ADL limitations in older adults of the Han nationality was 0.605 times that of the minority population. More highly educated and older adults without diseases have a lower risk of ADL limitations.

Conclusions

Compared with the national average in China, the number of ADL limitations of older adults in Ningxia is greater and is associated with advanced age, ethnic minority status, low education level, low income, lacking a spouse and having diseases. As the number of older adults increases, maintaining and improving their ability to perform ADL and providing comfortable pension services and health services urgently need to be solved.

Association Between Body Mass Index and Results of Rehabilitation in Patients After Stroke: A 3-Month Observational Follow-Up Study

Background

We assessed the relationship between body mass index and results of rehabilitation in stroke patients.

Material/Methods

The study was carried out at the Clinical Rehabilitation Ward with Early Neurological Rehabilitation Unit at the Clinical Hospital. The examinations were performed 3 times. Based on inclusion and exclusion criteria, 128 subjects were qualified for the first examination, the second examination involved 114 subjects, and 100 stroke patients participated in the third examination. Body mass was examined with an accuracy of 0.1 kg, using a Tanita MC–780 MA body composition analyser. Body mass index (BMI) was calculated for all of the subjects. Effects of rehabilitation were assessed with the Barthel index and Ashworth scale.

Results

Higher functional status in daily life, measured with the Barthel scale, was found in patients with normal body mass, compared to the overweight and obese subjects (examination I, II, and II). Exam I showed that before rehabilitation the overweight patients obtained significantly higher results in assessment of upper limbs, based on the Ashworth scale (mean=0.35±0.54) compared to the obese patients (mean=0.03±0.32) and those with normal body weight (mean=0.24±0.75).

Conclusions

Following hospital-based rehabilitation, patients with normal body mass achieved greater functional efficiency. The findings also show a trend towards normalization of BMI. The positive effect of rehabilitation was sustained for 3 months (Exam III), which may contribute to decreased risk of cardiovascular diseases and complications such as stroke.

Diet after Stroke and Its Impact on the Components of Body Mass and Functional Fitness-A 4-Month Observation

The aim of the study was to assess the effect of various diets on BMI and selected components of body mass, i.e., fat mass (FAT%), visceral fat (VFAT level), muscle mass (PMM %), body water (TBW %), and functional fitness during a 4-month observation period. Examinations were conducted three times in a group of 100 people after a stroke. The study group was divided into four subgroups according to the type of diet applied. The components of body mass were assessed using the electrical bioimpedance method, and functional fitness using the Barthel scale, the Brunnström scale, and the modified Ashworth scale. Despite the fact that there were no significant differences among the diets applied, it was observed that each of them had a positive effect on the reduction of the mean BMI, FAT%, VFAT level, and the increase in TBW% and PMM%. At the same time, there was a significant improvement in the functional fitness of the hand and upper limb. Weight control and a change in eating habits after a stroke incident is extremely important as it promotes faster recovery and improved functional fitness.

Clinical application of ICF key codes to evaluate patients with dysphagia following stroke

This study was aimed to identify and evaluate the International Classification of Functioning (ICF) key codes for dysphagia in stroke patients. Thirty patients with dysphagia after stroke were enrolled in our study. To evaluate the ICF dysphagia scale, 6 scales were used as comparisons, namely the Barthel Index (BI), Repetitive Saliva Swallowing Test (RSST), Kubota Water Swallowing Test (KWST), Frenchay Dysarthria Assessment, Mini-Mental State Examination (MMSE), and the Montreal Cognitive Assessment (MoCA). Multiple regression analysis was performed to quantitate the relationship between the ICF scale and the other 7 scales. In addition, 60 ICF scales were analyzed by the least absolute shrinkage and selection operator (LASSO) method. A total of 21 ICF codes were identified, which were closely related with the other scales. These included 13 codes from Body Function, 1 from Body Structure, 3 from Activities and Participation, and 4 from Environmental Factors. A topographic network map with 30 ICF key codes was also generated to visualize their relationships. The number of ICF codes identified is in line with other well-established evaluation methods. The network topographic map generated here could be used as an instruction tool in future evaluations. We also found that attention functions and biting were critical codes of these scales, and could be used as treatment targets.

Development of a Barthel Index based on dyspnea for patients with respiratory diseases

Background

As Barthel Index (BI) quantifies motor impairment but not breathlessness, the use of only this index could underestimate disability in chronic respiratory disease (CRD). To our knowledge, no study evaluates both motor and respiratory disability in CRD during activities of daily living (ADLs) simultaneously and with a unique tool. The objective of this study was to propose for patients with CRD an additional tool for dyspnea assessment during ADLs based on BI items named Barthel Index dyspnea.

Methods

Comprehensibility, reliability, internal consistency, validity, responsiveness, and ability to differentiate between disease groups were assessed on 219 subjects through an observational study performed in an in-hospital rehabilitation setting.

Results

Good comprehensibility, high reliability (interrater intraclass correlation coefficient was 0.93 [95% confidence interval 0.892–0.964] and test–retest intraclass correlation coefficient was 0.99 [95% confidence interval 0.983–0.994]), good internal consistency (Cronbach’s alpha 0.89), strong concurrent validity with 6 minute walking distance (Pearson r=−0.538, P<0.001) and Medical Research Council (Spearman r_S=0.70, P<0.001), good responsiveness after rehabilitation (P<0.001), and good appropriateness of the index were found evidencing patients with different dyspnea severity. Divergent validity showed weak correlation (Pearson r=−0.38) comparing Barthel Index dyspnea and BI.

Conclusion

The BI based on dyspnea perception proved to be reliable, sensitive, and adequate as a tool for measuring the level of dyspnea perceived in performing basic daily living activities. A unique instrument simultaneously administered may provide a global assessment of disability during ADLs incorporating both motor and respiratory aspects.

Stroke Treatment Associated with Rehabilitation Therapy and Transcranial DC Stimulation (START-tDCS): a study protocol for a randomized controlled trial

Background

Traditional treatment for motor impairment after stroke includes medication and physical rehabilitation. The transcranial direct current stimulation associated with a standard physical therapy program may be an effective therapeutic alternative for these patients.

Methods

This study is a sham-controlled, double-blind, randomized clinical trial aiming to evaluate the efficacy of transcranial direct current stimulation in activities of daily living and motor function post subacute stroke. In total there will be 40 patients enrolled, diagnosed with subacute, ischemic, unilateral, non-recurring stroke. Participants will be randomized to two groups, one with active stimulation and the other with a placebo current. Patients and investigators will be blinded. Everyone will receive systematic physical therapy, based on constraint-induced movement therapy. The intervention will be applied for 10 consecutive days. Patients will undergo three functional assessments: at baseline, week 2, and week 4. Neuropsychological tests will be performed at baseline and week 4. Adverse effects will be computed at each session. On completion of the baseline measures, randomization will be conducted using random permuted blocks. The randomization will be concealed until group allocation.

Discussion

This study will investigate the combined effects of transcranial direct current stimulation and physical therapy on functional improvement after stroke. We tested whether the combination of these treatments is more effective than physical therapy alone when administered in the early stages after stroke.

Trial registration

NCT02156635 - May 30, 2014. Randomization is ongoing (40 participants randomized as of the end of December 2015).
