: Neurological dysfunction due to stroke affects not only the extremities and trunk muscles but also the respiratory muscles. : to synthesise the evidence available about the effectiveness of respiratory muscle training (RMT) to improve respiratory function parameters and functional capacity in poststroke patients. : a systematic electronic search was performed in the MEDLINE, EMBASE, SPORTDiscus, PEDro and Web of Science databases, from inception to May 2020. : randomised controlled trials (RCTs) that examined the effects of RMT versus non-RMT or sham RMT in poststroke patients. We extracted data about respiratory function, respiratory muscle strength and functional capacity (walking ability, dyspnea, balance, activities of daily life), characteristics of studies and features of RMT interventions (a type of RMT exercise, frequency, intensity and duration). Two reviewers performed study selection and data extraction independently. : nineteen RCTs met the study criteria. RMT improved the first second forced expiratory volume (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), maximal expiratory pressure (MEP), maximal inspiratory pressure (MIP) and walking ability (6 min walking test), but not Barthel index, Berg balance scale, and dyspnea. : RMT interventions are effective to improve respiratory function and walking ability in poststroke patients.

OBJECTIVE:Inspiratory and expiratory muscles are important for effective respiratory function. This study aimed to investigate the efficacy of bedside respiratory muscle training on pulmonary function and stroke-related disabilities in stroke rehabilitation. DESIGN:Patients with stroke (N = 40) in a rehabilitation unit were randomly assigned to either the intervention group (n1 = 20) or the control group (n2 = 20). Both groups participated in a conventional stroke rehabilitation program. During the study period, the intervention group received bedside respiratory muscle training twice a day for 3 wks. The respiratory muscle training consisted of (1) a breath stacking exercise, (2) inspiratory muscle training, and (3) expiratory muscle training. The primary outcomes were measures of pulmonary function: forced vital capacity, forced expiratory volume in 1 sec, and peak flow. Secondary outcomes were stroke-related disabilities assessed using the National Institutes of Health Stroke Scale, Modified Barthel Index, Berg Balance Scale, Fugl-Meyer Assessment, the Korean Mini-Mental State Examination, and pneumonia incidence. RESULTS:Pulmonary function was significantly improved in the intervention group after 3 wks of respiratory muscle training (P < 0.05). This improvement in pulmonary function was independent of the improvement in stroke-related disabilities. CONCLUSION:Three weeks of respiratory muscle training had significant effects on pulmonary function in stroke survivors.

BACKGROUND AND PURPOSE:Disabling anxiety affects a quarter of stroke survivors but access to treatment is poor. We developed a telemedicine model for delivering guided self-help cognitive behavioral therapy (CBT) for anxiety after stroke (TASK-CBT). We aimed to evaluate the feasibility of TASK-CBT in a randomized controlled trial workflow that enabled all trial procedures to be carried out remotely. In addition, we explored the feasibility of wrist-worn actigraphy sensor as a way of measuring objective outcomes in this clinical trial. METHODS:We recruited adult community-based stroke patients (n=27) and randomly allocated them to TASK-CBT (n=14) or relaxation therapy (TASK-Relax), an active comparator (n=13). RESULTS:In our sample (mean age 65 [±10]; 56% men; 63% stroke, 37% transient ischemic attacks), remote self-enrolment, electronic signature, intervention delivery, and automated follow-up were feasible. All participants completed all TASK-CBT sessions (14/14). Lower levels of anxiety were observed in TASK-CBT when compared with TASK-Relax at both weeks 6 and 20. Mean actigraphy sensor wearing-time was 33 days (±15). CONCLUSIONS:Our preliminary feasibility data from the current study support a larger definitive clinical trial and the use of wrist-worn actigraphy sensor in anxious stroke survivors.

The risks of stroke and dementia increase steeply with age, and both are preventable. At present, the best way to preserve cognitive function is to prevent stroke. Therapeutic nihilism based on age is common and unwarranted. We address recent advances in stroke prevention that could contribute greatly to prevention of stroke and dementia at a time when the aging of the population threatens to markedly increase the incidence of both. Issues discussed: (1) old patients benefit even more from lipid-lowering therapy than do younger patients; (2) patients with stiff arteries are at risk from a target systolic blood pressure <120 mm Hg; (3) the interaction of the intestinal microbiome, age, and renal function has important dietary implications for older adults; (4) anticoagulation with direct-acting oral anticoagulants should be prescribed more to old patients with atrial fibrillation; (5) B vitamins to lower homocysteine prevent stroke; and (6) most old patients in whom intervention is warranted for carotid stenosis would benefit more from endarterectomy than from stenting. An 80-year-old person has much to lose from a stroke and should not have effective therapy withheld on account of age. Lipid-lowering therapy, a more plant-based diet, appropriate anticoagulation or antiplatelet therapy, appropriate blood pressure control, B vitamins to lower homocysteine, and judicious intervention for carotid stenosis could do much to reduce the growing burden of stroke and dementia.

BACKGROUND AND PURPOSE:Medical complications are common among patients with stroke. However, little is known about the potential interrelationship among them. In the present study, we aimed to investigate the association between common in-hospital medical complications after acute ischemic stroke (AIS) and spontaneous intracerebral hemorrhage (ICH). METHODS:We analyzed patients enrolled in the China National Stroke Registry from 2007 to 2008. The occurrence of 11 common stroke-associated medical complications during acute hospitalization was prospectively registered. Multivariable analysis using generalized estimation equation was performed to assess association between medical complications in AIS and ICH cohort, respectively. RESULTS:A total of 14 702 patients with AIS and 5221 patients with ICH were enrolled. The median age was 65 years (interquartile range, 55-74 years), and 38.1% were female. The median length of hospital stay was 14 days (interquartile range, 10-20 days) for AIS and 18 days (interquartile range, 11-26 days) for ICH. Pneumonia was the most common medical complication after AIS (11.4%) and ICH (16.8%). In the AIS cohort, after adjusting for potential confounders, pneumonia was significantly associated with development of gastrointestinal bleeding (adjusted odds ratio [OR], 8.35; 95% confidence interval [CI], 6.27-11.1; P<0.001), decubitus ulcer (adjusted OR, 5.31; 95% CI, 3.39-8.31; P<0.001), deep vein thrombosis (adjusted OR, 4.27; 95% CI, 2.41-7.59; P<0.001), epileptic seizure (adjusted OR, 3.96; 95% CI, 2.67-5.88; P<0.001), urinary tract infection (adjusted OR, 3.34; 95% CI, 2.73-4.10; P<0.001), atrial fibrillation/flutter (adjusted OR, 3.17; 95% CI, 2.58-3.90; P<0.001), and recurrent stroke (adjusted OR, 2.65; 95% CI, 2.07-3.40; P<0.001). Similar significant association between pneumonia and development of several nonpneumonia medical complications was verified in ICH cohort as well. CONCLUSIONS:Pneumonia is closely associated with the development of several nonpneumonia medical complications after AIS and ICH.

BACKGROUND:Patients admitted for rehabilitation often lack sufficient natural light to entrain their circadian rhythm. OBJECTIVE:Installed diurnal naturalistic light may positively influence the outcome of depressive mood, anxiety, and cognition in such patients. METHODS:A quasi-randomized controlled trial. Ninety stroke patients in need of rehabilitation were randomized between May 1, 2014, and June 1, 2015 to either a rehabilitation unit equipped entirely with always on naturalistic lighting (IU), or to a rehabilitation unit with standard indoor lighting (CU).Examinations were performed at inclusion and discharge. The following changes were investigated: depressive mood based on the Hamilton Depression scale (HAM-D6) and Major Depression Inventory scale (MDI), anxiety based on the Hospital Anxiety and Depression Scale (HADS), cognition based on the Montreal Cognitive Assessment (MoCA) and well-being based on the Well-being Index (WHO-5). RESULTS:Depressive mood (MDI p = 0.0005, HAM-D6 p = 0.011) and anxiety (HADS anxiety p = 0.045) was reduced, and well-being (WHO-5 p = 0.046) was increased, in the IU at discharge compared to the CU. No difference was found in cognition (MoCA p = 0.969). CONCLUSIONS:This study is the first to demonstrate that exposure to naturalistic light during admission may significantly improve mental health in rehabilitation patients. Further studies are needed to confirm these findings.

Purpose The high incidence of swallowing and communication disorders following stroke is well documented. However, many of these studies have used retrospective chart reviews to make estimates of incidence and co-occurrence. The current study prospectively examined the incidence and co-occurrence of dysphagia, dysarthria, and aphasia following a 1st occurrence of ischemic stroke at an academic medical center hospital. Method One hundred patients who experienced their 1st ischemic stroke were recruited for participation in this study. All participants received a clinical swallowing evaluation to assess for dysphagia, administration of the Frenchay Dysarthria Assessment-Second Edition ( Enderby & Palmer, 2008 ) and Western Aphasia Battery-Revised ( Kertesz, 2006 ) to screen for the presence of dysarthria and aphasia, respectively. Results Incidence rates of dysphagia, dysarthria, and aphasia were 32%, 26%, and 16%, respectively. Forty-seven percent of participants had at least 1 of these disorders, 28% had 2 of these disorders, and 4% had all 3. Although the incidence rates in this study were smaller in magnitude than incidence rates in previous research, the pattern of results is broadly similar (i.e., dysphagia had the highest incidence rate, followed by dysarthria and, lastly, aphasia). Conclusions This prospective study yielded slightly lower incidence rates than have been previously obtained from retrospective chart reviews. The high incidence and co-occurrence of devastating swallowing and communication disorders post-ischemic stroke provides clear motivation for speech-language pathology involvement in the early phase of stroke rehabilitation.
