BACKGROUND AND PURPOSE Stroke is a leading cause of disability. Rehabilitation robotics have been developed to aid in recovery after a stroke. This study determined the additional cost of robot-assisted therapy and tested its cost-effectiveness. METHODS We estimated the intervention costs and tracked participants' healthcare costs. We collected quality of(More)
BACKGROUND AND PURPOSE Resistance to insulin-mediated glucose uptake by peripheral tissues is a cardinal defect in type 2 diabetes mellitus. Insulin resistance is also common among nondiabetic individuals, and may be an important risk factor for stroke in both populations. The authors review the definition, epidemiology, and treatment of insulin resistance.(More)
OBJECTIVES To determine the prevalence of impaired insulin sensitivity among nondiabetic patients with a recent TIA or nondisabling ischemic stroke. METHODS Eligible subjects were nondiabetic men and women over age 45 years who were hospitalized with a TIA or ischemic stroke. To measure insulin sensitivity, subjects underwent an oral glucose tolerance(More)
BACKGROUND AND PURPOSE Quality of care delivered in the inpatient and ambulatory settings may be correlated within an integrated health system such as the Veterans Health Administration. We examined the correlation between stroke care quality at hospital discharge and within 6 months postdischarge. METHODS We conducted a cross-sectional hospital-level(More)
BACKGROUND Chronic upper extremity impairment due to stroke has significant medical, psychosocial, and financial consequences, but few studies have examined the effectiveness of rehabilitation therapy during the chronic stroke period. OBJECTIVE . To test the safety and efficacy of the MIT-Manus robotic device for chronic upper extremity impairment(More)
Falls are common after stroke; however, circumstances and consequences are relatively unknown. Our objectives were to identify the differences between fallers and non-fallers among people with chronic stroke, identify the circumstances of fall events, and examine the consequences of the falls. This is a secondary data analysis; all participants included(More)
AIMS We derived and validated a clinical prediction rule that can be used to predict post-stroke pneumonia. METHODS We conducted a retrospective cohort study of patients admitted to hospital with a stroke. The cohort was subdivided into a derivation group and a validation group. Within the derivation group, a point scoring system was developed to predict(More)
BACKGROUND Clinicians need self-directed learning skills to maintain competency. The objective of this study was to develop and implement a curriculum to teach physicians self-directed learning skills during inpatient ward rotations. METHODS Residents and attendings from an internal medicine residency were assigned to intervention or control groups;(More)
BACKGROUND The treatment of hypertension is an essential component of stroke prevention; however, the clinical management of patients with cerebrovascular disease is complicated by orthostatic hypotension (OH). The primary objectives were to: determine the prevalence of OH in a stroke outpatient clinic; describe categories of OH; and identify factors(More)
BACKGROUND Prior research has indicated an association between insulin resistance and stroke; we sought to determine if this association persists after adjusting for stroke risk factors, including glycemic control. METHODS We used data from the Third National Health and Nutrition Survey (1988-1994), including participants aged > or =40 years. We assessed(More)
