ObjectiveTo evaluate the effect of anodal transcranial direct current stimulation (tDCS) over the lesioned leg motor cortex, which can enhance the strength and coordination of the contralateral lower extremity and furthermore, enhance the postural stability of the hemiplegic subject.MethodsAnodal or sham stimulation on the lesioned cortex of a lower extremity was delivered to 11 ambulatory hemiplegic patients. The stimulation intensity was 2 mA. All subjects took part in two 10-minute tDCS sessions consisting of anodal stimulation and sham stimulation. The interval period between real and sham stimulation was 48 hours. The order was counter-balanced among the subjects. Before and after each stimulation session, static postural stability was evaluated with eyes opened and closed. Also, the isometric strength of the hemiplegic side of the treated knee was measured before and after each stimulation session. Repeated measure ANOVA was used to determine the statistical significance of improvements in postural stability and strength.ResultsThere was significant improvement for overall stability index with eyes opened and closed after anodal tDCS (p<0.05). Isometric strength of the lesioned quadriceps tended to increase after anodal tDCS (p<0.05). Postural stability and quadriceps strength were not changed after sham stimulation.ConclusionAnodal tDCS has potential value in hemiplegic stroke patients to improve balance and strengthen the affected lower extremity.
Predicting functional outcome and quality of life (QOL) is critical to the treatment of patients with stroke. The purpose of this study was to analyze the factors influencing functional status and QOL of stroke patients 6 months after a first-ever stroke. This study was an interim analysis of the Korean Stroke Cohort for Functioning and Rehabilitation Study, designed to include 10 years of follow-up for first-ever stroke patients. This study analyzed data from 2857 patients who completed face-to-face assessments with the functional independence measurement (FIM) and Euro Quality of Life-5D (EQ-5D) at 6 months after stroke onset. A multivariate regression analysis was used to analyze factors that potentially influenced FIM and EQ-5D results at 6 months after stroke. Of the patients in this study, 80.1 % suffered from ischemic stroke and 19.9 % experienced hemorrhagic stroke. The independent predictors of functional independency measured by FIM at 6 months after stroke were age, initial stroke severity, duration of hospitalization, and functional level at discharge in terms of motor, ambulation, and language. For QOL measured by EQ-5D at 6 months after stroke, age, duration of hospitalization, and motor function at discharge were significant predictors. In conclusion, proper treatment to achieve maximal functional gain at discharge may be an important factor in improving functional independency and QOL in chronic stage stroke survivors. These results provide useful information for establishing comprehensive and systematic care for stroke patients.
Assessment of functional independence and residual disability is very important for measuring treatment outcome after stroke. The modified Rankin Scale (mRS) and the modified Barthel Index (MBI) are commonly used scales to measure disability or dependence in activities of daily living (ADL) of stroke survivors. Lack of consensus regarding MBI score categories has caused confusion in interpreting stroke outcomes. The purpose of this study was to identify the optimal corresponding MBI and modified Rankin scale (mRS) grades for categorization of MBI. The Korean versions of the MBI (K-MBI) and mRS were collected from 5,759 stroke patients at 3 months after onset of stroke. The sensitivity and specificity were calculated at K-MBI score cutoffs for each mRS grade to obtain optimally corresponding K-MBI scores and mRS grades. We also plotted receiver operating characteristic (ROC) curves of sensitivity and specificity and determined the area under the curve (AUC). The K-MBI cutoff points with the highest sum of sensitivity and specificity were 100 (sensitivity 0.940; specificity 0.612), 98 (sensitivity 0.904; specificity 0.838), 94 (sensitivity 0.885; PLOS ONE | https://doi.
ObjectiveTo evaluate the effectiveness of initial extracorporeal shock wave therapy (ESWT) for patients newly diagnosed with lateral or medial epicondylitis, compared to local steroid injection.MethodAn analysis was conducted of twenty-two patients who were newly confirmed as lateral or medial epicondylitis through medical history and physical examination. The ESWT group (n=12) was treated once a week for 3 weeks using low energy (0.06-0.12 mJ/mm2, 2,000 shocks), while the local steroid injection group (n=10) was treated once with triamcinolone 10 mg mixed with 1% lidocaine solution. Nirschl score and 100 point score were assessed before and after the treatments of 1st, 2nd, 4th and 8th week. And Roles and Maudsley score was assessed one and eight weeks after the treatments.ResultsBoth groups showed significant improvement in Nirschl score and 100 point score during the entire period. The local steroid injection group improved more in Nirschl score at the first week and in 100 point score at the first 2 weeks, compared to those of the ESWT group. But the proportion of excellent and good grades of Roles and Maudsley score in the ESWT group increased more than that of local steroid injection group by the final 8th week.ConclusionThe ESWT group improved as much as the local steroid injection group as treatment for medial and lateral epicondylitis. Therefore, ESWT can be a useful treatment option in patients for whom local steroid injection is difficult.
Objective: To investigate the return to work status of patients with first-ever stroke with functional independence 6 months post-stroke. Design: Prospective cohort study. Participants: Nine hundred and thirty-three patients with functional independence at 6 months after stroke onset. Methods: A complete post-enumeration survey was performed through a review of the medical records for first admission. In addition, structured self-administered questionnaires and a face-to-face interview were performed assessing occupational status, quality of life, and emotional status at 6 months after stroke. Results: Of the patients in this study, 60.0% returned to work at 6 months after stroke. Sex, age, educational level, and comorbidity level were independent factors related to return to work. The rate of return to work in female patients under 65 years of age was similar to that of male patients 65 years of age or older. Stroke patients who returned to work showed better emotional statuses than those who did not return to work. Conclusion: Many stroke patients did not return to work despite functional independence at 6 months after stroke. Based on the results of this study, we suggest providing appropriate vocational rehabilitation for stroke patients and proper education for employers to increase the rate of early return to work in stroke patients.
BackgroundDevelopment of a long-term stroke care plan requires serial assessment of long-term patient function and consideration of caregiver mood. However, to date, few comprehensive cohort studies have included both stroke patients and caregivers.Methods/DesignKOSCO is a large, multi-centre prospective cohort study for all acute first-ever stroke patients admitted to participating hospitals in nine distinct areas of Korea. This study is designed as a 10-year, longitudinal follow-up investigating the residual disabilities, activity limitations, and quality of life issues arising in patients suffering from first-ever stroke. The main objectives of this study are to identify the factors that influence residual disability and long-term quality of life. The secondary objectives of this study are to determine the risk of mortality and recurrent vascular events in patients with acute first-ever stroke. We will investigate longitudinal health behaviors and patterns of healthcare utilization, including stroke rehabilitation care. We will also investigate the long-term health status, mood, and quality of life in stroke patient caregivers. In addition, we will identify baseline and ongoing characteristics that are associated with our secondary outcomes.DiscussionKOSCO is a prospective, multi-centre, 10-year longitudinal follow-up study investigating the residual disabilities, activity limitations, and quality of life issues arising in patients suffering from first-ever stroke.
ObjectivesWe examined whether obesity based on body mass index (BMI) was a predictor of functional independence measure (FIM) at 6 months after ischaemic stroke onset while adjusting for stroke risk factors and covariates and stratifying by age group.DesignThis is an interim report of the Korean Stroke Cohort for Functioning and Rehabilitation that was designed as a nested case study within a nationwide hospital-based cohort.SettingWe identified all patients who were admitted to nine representative hospitals in Korea from 2012 until 2014 under a diagnosis of acute first-ever ischaemic stroke. The hospitals were selected from the metropolitan district, mid-sized cities and a small-sized city.ParticipantsThe sample included 2057 patients with acute ischaemic stroke who were at least 18 years old.Primary and secondary outcome measuresWe divided participants into two age levels (<65 and ≥65 years). Participants were classified into five groups according to their baseline BMI at admission: underweight (BMI<18.5), normal (18.5≤BMI<23), overweight (23≤BMI<25), obese (25≤BMI<30) and extremely obese (30≤BMI).ResultsThe proportion of patients who were aged ≥65 years was 55.0%. The proportions of underweight, normal, overweight, obese and extremely obese patients were 2.6%, 24.3%, 29.6%, 37.2% and 6.3%, respectively, in the <65 years group and 5.5%, 34.5%, 27.9%, 28.8% and 3.3%, respectively, in the ≥65 years group. In a multiple linear regression, the 6-month FIM after stroke in the elderly group was significantly associated with being extremely obese (7.95, p<0.05) after adjusting for confounding variables. In the <65 years group, the 6-month FIM was not associated with any weight category.ConclusionsThis nationwide hospital-based cohort study showed that extreme obesity is a predictor of a good 6-month FIM, especially in patients with ischaemic stroke who are at least 65 years of age.
