Abstract
Poststroke anxiety and depressive symptoms (P-SADS) affect one in three people and are associated with decreased participation in activities of daily living. This study sought to characterize occupational therapy (OT) P-SADS care practices and identify factors influencing P-SADS care provision in one U.S. inpatient rehabilitation (IRF) facility. An explanatory sequential mixed-methods study design was used by gathering data from electronic health records (from January 1, 2019 to December 31, 2019) as well as semi-structured interviews with OT practitioners in the IRF. No objective P-SADS screens were documented nor were any P-SADS-focused goals written. Minimal evidence-based P-SADS interventions were identified. Practitioners reported multi-level barriers to OT P-SADS care including limited time, pressure to prioritize physical recovery, and inadequate resources to guide practice. OT practitioner P-SADS care was inconsistent with established evidence-based practice. This research identifies gaps in comprehensive stroke recovery and informs implementation efforts to support evidence-based P-SADS care in IRFs.

Applying transcranial magnetic stimulation to rehabilitation of poststroke lower extremity function and an improvement: Individual-target TMS. WILEY INTERDISCIPLINARY REVIEWS. COGNITIVE SCIENCE 2023; 14:e1636. [PMID: 36437474 DOI: 10.1002/wcs.1636] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 09/21/2022] [Accepted: 10/26/2022] [Indexed: 11/29/2022]
Abstract
Stroke is the leading cause of disability globally in need of novel and effective methods of rehabilitation. Intermittent theta burst stimulation (iTBS) has been adopted as a Level B recommendation for lower limb spasticity in guidelines on the therapeutic use of repetitive transcranial magnetic stimulation (rTMS). Nonetheless, the methodological differences and deficits of existing work bring about heterogenous results and therefore limit the universal clinical use of rTMS in lower extremity (LE) rehabilitation. The variation of stimulated targets across motor cortex contributes mainly to these heterogeneities. This narrative review includes studies of rTMS on LE motor function rehabilitation in patients after stroke until now. Some analyses of brain imaging and electromagnetic simulation and quantification through computational modeling were also performed. rTMS appears capable of fostering LE motor rehabilitation after stroke, but the actually stimulated targets are considerably bias making it difficult to confirm effectiveness. The main reason for this phenomenon is probably inaccurate targeting of motor cortical leg representation. An underlying updated method is proposed as Individual-Target TMS (IT-TMS) combined with brain imaging. rTMS is a promising validated method for LE function regaining. Future studies should systematically compare the effects of IT-TMS with traditional rTMS using large samples in random clinical trials. This article is categorized under: Neuroscience > Clinical Neuroscience.

Effectiveness and Safety of Lacosamide, A Third-generation Anti-seizure Medication, for Poststroke Seizure and Epilepsy: A Literature Review. Curr Neuropharmacol 2023; 21:2126-2133. [PMID: 37340744 PMCID: PMC10556369 DOI: 10.2174/1570159x21666230616114255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 12/07/2022] [Accepted: 12/12/2022] [Indexed: 06/17/2023] Open
Abstract
Advances in stroke treatment have resulted in a dramatic reduction in stroke mortality. Nevertheless, poststroke seizures and epilepsy are issues of clinical importance affecting survivors. Additionally, stroke is the most common cause of epilepsy in older adults. Although numerous antiseizure medications exist, studies are needed to provide robust evidence of the efficacy and tolerability of these medicines for treating poststroke seizures and epilepsy. Crucially, the newer generations of antiseizure medications require testing. Lacosamide, a third-generation antiseizure medication approved for treating localization-related epilepsy, has a novel mechanism of selectively enhancing the slow inactivation of sodium channels. This literature review evaluated whether lacosamide is effective and safe for the treatment of poststroke seizures and epilepsy. This review critically analyzed studies published in major academic databases (Pubmed, Embase, and Cochrane Library) from inception through June 2022 regarding the interaction of lacosamide with poststroke seizures and epilepsy. We included clinical prospective, retrospective, and case studies on patients with poststroke seizure and epilepsy, lacosamide as a treatment for seizures, neuroprotection in animal models of seizures, and the safety of lacosamide when coadministering anticoagulants. Clinical studies revealed lacosamide to be an effective antiseizure medication with high efficacy and tolerability in patients with poststroke seizures and epilepsy. In animal models, lacosamide proved effective at seizure reduction and neuroprotection. Pharmacokinetic studies demonstrated the safety of lacosamide when coadministering conventional and new anticoagulants. The literature suggests that Lacosamide is a promising candidate antiseizure medication for patients with poststroke seizures and epilepsy.

Fitting the task to a person with disabilities: A case of return-to-work support for a patient due to left-sided poststroke hemiplegia using tailor-made jigs-and-tools. J Occup Health 2021; 63:e12201. [PMID: 33528055 PMCID: PMC7851845 DOI: 10.1002/1348-9585.12201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Revised: 01/08/2021] [Accepted: 01/15/2021] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND A 45-year-old Japanese male pharmacist developed a stroke in December 2018; hence, he had left-sided hemiplegia due to the after-effects of cerebral stroke. This paper reports the return-to-work (RTW) and after RTW support for poststroke patients from a combined ergonomic and rehabilitation perspective. METHODS From April 2019 to July 2020, we visited hospitals and workplaces multiple times, making various preparations for workplace accommodation and exchanging information as follows: allowing staggered working hours; securing the flow routes in the back room; equipping a cane holder on his working desk; and adjusting the position of the work tablet. In August 2020, after RTW, we conducted a brief evaluation of residual motor function and an on-site task analysis, and we subsequently made a support tool. RESULTS In July 2020, his RTW was eventually realized. Moreover, as a result of introducing the tailor-made support tool, the duration of certain tasks that he had been claiming to be difficult was reduced when compared to that before support-tool use, and the average task duration before and after support-tool use was 32.8 s and 10 s, respectively (reduced by approximately 69.5%). CONCLUSION To augment our efforts, hospital staff, support staff in his workplace, and his employer collaborated to make various workplace accommodations for the smooth realization of RTW before and after RTW. In the present case, the ergonomic and rehabilitation approach after RTW might have contributed to ease of task, work efficiency, and the potential for future job retention.

Abstract
Background
Stroke is one of the most debilitating conditions contributing to significant disability and death globally. Identifying risk factors for quality of life (QoL) will enable to improve home-based rehabilitation in post-stroke phase.
Objective
This study was aimed to identify the risk factors of QoL in stroke patients in the sub-Himalayan region.
Materials and Methods
A cross-sectional hospital-based study assessed the QoL among stroke patients within a week after the onset of acute stroke and then re-evaluated at 3 months. World Health Organization QoL-BREF, Beck Depression Inventory, the Barthel Index, and Montreal Cognitive Assessment (MOCA) were used to seek data on QoL, depression, cognitive, and functional dependence status, respectively. Appropriate statistics were used to compute the results.
Results
In total, 129 stroke patients recruited, out of which 102 returned to a 3-month follow-up. QoL, MOCA, disability index, and depression score were compared using Wilcoxon Singed-rank test. In multivariate analysis, depression and disability together predicted 60% of the variance for physical QoL (
p
< 0.0001). Similarly, poststroke depression and disability together predicted 61% of the variance for psychological QoL (
p
< 0.0001) in stroke patients.
Conclusion
Findings indicated that depression and disability are leading risk factors of QoL in stroke patients. Early identification of poststroke depression and functional dependence status is, therefore, essential to devise screening procedure and to develop targeted intervention to improve rehabilitation outcomes.

Abstract
Vinpocetine (VPN) is a synthetic ethyl-ester derivative of the alkaloid apovincamine from Vinca minor leaves. VPN is a selective inhibitor of phosphodiesterase type 1 (PDE1) that has potential neurological effects through inhibition of voltage-gated sodium channel and reduction of neuronal calcium influx. VPN has noteworthy antioxidant, anti-inflammatory, and anti-apoptotic effects with inhibitory effect on glial and astrocyte cells during and following ischemic stroke (IS). VPN is effective as adjuvant therapy in the management of epilepsy; it reduces seizure frequency by 50% in a dose of 2 mg/kg/day. VPN improves psychomotor performances through modulation of brain monoamine pathway mainly on dopamine and serotonin, which play an integral role in attenuation of depressive symptoms. VPN recover cognitive functions and spatial memory through inhibition of hippocampal and cortical PDE1 with augmentation of cyclic adenosin monophosphate and cyclic guanosin monophosphate ratio, enhancement of cholinergic neurotransmission, and inhibition of neuronal inflammatory mediators. Therefore, VPN is an effective agent in the management of IS and plays an integral role in the prevention and attenuation of poststroke epilepsy, depression, and cognitive deficit through direct cAMP/cGMP-dependent pathway or indirectly through anti-inflammatory and antioxidant effects.

Abstract
Background Stroke is one of the top 10 leading diseases worldwide, with high mortality and morbidity rates. There is an incomplete understanding of the various types of self-efficacy involved in the prevention of recurrent stroke, and one of them is medication-taking self-efficacy. Objective This study aimed to explore the fundamental needs and barriers of medication-taking self-efficacy in poststroke patients in Malaysia. Methods We performed in-depth individual interviews with poststroke patients (N=10) from the Outpatient Neurology Clinic, Hospital Kuala Lumpur. All interviews were transcribed verbatim, and an inductive thematic analysis was performed on the data collected from the interviews. Results Two key themes were identified: (1) self-efficacy in taking the effort to understand stroke and its preventative treatment for recurrent stroke and (2) self-efficacy in taking prescribed medication to prevent stroke. Patients needed to be proactive in seeking reliable information about stroke and the perceived benefits of preventative treatment for stroke. The discussion was focused on eliciting the needs and barriers related to medication-taking self-efficacy. Patients needed to develop independence and self-reliance to overcome barriers such as dependency and low motivation. External factors such as limited information resources, low perceived severity, poor social environment, and poor communication add to the challenges of poststroke patients to improve their self-efficacy of managing their medications. Conclusions The study identified potential key findings related to the needs of patients in a localized setting, which are also related to several health behavioral concepts and constructs, indicating the importance of overcoming barriers to improve the quality of life in poststroke patients. We anticipate that the results will be taken into consideration for future personalized patient education interventions.

Effect of single-nucleotide polymorphism in pri-microRNA-124 on poststroke motor function recovery. J Cell Biochem 2019; 120:7125-7132. [PMID: 30548296 DOI: 10.1002/jcb.27986] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2018] [Accepted: 10/08/2018] [Indexed: 01/24/2023]
Abstract
BACKGROUND Stroke is a leading cause of long-term disability and further one of the main causes of motor impairment. The current study aimed to investigate whether miR-124 polymorphism (rs531564) influences the motor function of patients after stroke. METHODS In total, 56 patients with stroke-induced motor dysfunction were enrolled. Box and block test (BBT) and Fugl-Meyer assessment (FMA) were performed to evaluate the motor functions in all participants. Computation analysis, luciferase activity, PCR assays, and Western blot analysis were performed to reveal the molecular mechanism underlying the effect of miR-124 polymorphism on motor functions. RESULTS The 56 participants were genotyped as CC, CG, and GG, respectively. The serum miR-124 was significantly upregulated in the CC group than that in the GC and GG groups. According to the result of FMA or BBT, there was no obvious difference in upper and lower limb motor functions between CC and CG/GG groups 1 week after the treatment. In addition, scores of BBT and FMA exhibited apparent improvement in both groups at 1 month and 3 months after the treatment. Furthermore, improvements in the CG/GG groups were more significant as compared with those in the CC group. CDK4 was a target of miR-124, and the effect of miR-124 on the motor function recovery might be mediated by CDK4. CONCLUSION The presence of a minor allele, G, of miR-124 polymorphism (rs531564) reduced the expression of miRNA and upregulated the expression of CDK4, which may contribute to the effect of rs531564 on the motor function recovery in poststroke patients.

Combined Effects of Isokinetic Training and Botulinum Toxin Type A on Spastic Equinus Foot in Patients with Chronic Stroke: A Pilot, Single-blind, Randomized Controlled Trial. Toxins (Basel) 2019; 11:toxins11040210.

Abstract
Botulinum toxin A (BoNT-A) has been shown effective for poststroke lower limb spasticity. Following injections, a wide range of multidisciplinary approach has been previously provided. The purpose of this pilot, single-blind, randomized controlled trial was to determine whether BoNT-A combined with a regime of a four-week ankle isokinetic treatment has a positive effect on function and spasticity, compared with BoNT-A alone. Secondly, the validity of the use of an isokinetic dynamometer to measure the stretch reflex at the ankle joint and residual strength has been investigated. Twenty-five chronic stroke patients were randomized to receive combined treatment (n = 12; experimental group) or BoNT-A alone (n = 13; control group). Outcome measures were based on the International Classification of Functioning, Disability and Health. An isokinetic dynamometer was also used for stretch reflex and strength assessment. Patients were evaluated at baseline (t0), after five (t1) and eight weeks after the injection (t2). The experimental group reported significantly greater improvements on lower limb spasticity, especially after eight weeks from baseline. Gait speed (10-m walk test) and walking capacity (6-min walking test) revealed statistically significantly better improvement in the experimental than in control group. Peak resistive ankle torque during growing angular velocities showed a significant reduction at the higher velocities after BoNT-A injections in the experimental group. Peak dorsiflexor torque was significantly increased in the experimental group and peak plantarflexor torque was significantly decreased in control group. Alternative rehabilitation strategies that combine BoNT-A and an intense ankle isokinetic treatment are effective in reducing tone and improving residual strength and motor function in patients with chronic hemiparesis.

Exploring stroke survivors' self-efficacy in understanding and taking medication and determining associated factors: a cross-sectional study in a neurology clinic in Malaysia. Patient Prefer Adherence 2019; 13:1463-1475.

Abstract
BACKGROUND AND AIM Evidence-based prescribing practices for stroke-preventive medication have benefited stroke survivors; however, medication-nonadherence rates remain high. Medication understanding and use self-efficacy (MUSE) has shown great importance in medication-taking behavior, but its relationship with medication nonadherence in stroke-preventive regimens lacks exploration. The aim of this study was to determine the prevalence of MUSE and its association with nonadherence causes and other potential factors among stroke survivors in Malaysia. METHODS This cross-sectional study was conducted among 282 stroke patients who provided informed consent and were in follow-up at the Neurology Outpatient Department of Hospital Kuala Lumpur, Malaysia. The study employed a data-collection form that gathered information on sociodemographics, clinical treatment, outcome measures on MUSE, and medication-nonadherence reasons. RESULTS The prevalence of poor medication understanding and use self-efficacy among stroke patients was 46.5%, of which 29.1% had poor "learning about medication" self-efficacy, while 36.2% lacked self-efficacy in taking medication. Beliefs about medicine (74.02%) was the commonest reason for medication nonadherence, followed by medication-management issues (44.8%). In the multivariate model, independent variables significantly associated with MUSE were health literacy (AOR 0.2, 95% CI 0.069-0.581; P=0.003), medication-management issues (AOR 0.073, 95% CI 0.020-0.266; P<0.001), multiple-medication issues (AOR 0.28, 95% CI 0.085-0.925; P=0.037), beliefs about medicine (AOR 0.131, 95% CI 0.032-0.542; P=0.005), and forgetfulness/convenience issues (AOR 0.173, 95% CI 0.050-0.600; P=0.006). CONCLUSION The relatively poor learning about medication and medication-taking self-efficacy in this study was highly associated with health literacy and modifiable behavioral issues related to nonadherence, such as medication management, beliefs about medicine, and forgetfulness/convenience. Further research ought to explore these underlying reasons using vigorous techniques to enhance medication understanding and use self-efficacy among stroke survivors to determine cause-effect relationships.

Abstract
Walking can be exceedingly complex to analyze due to highly nonlinear multi-body dynamics, nonlinear relationships between muscle excitations and resulting muscle forces, dynamic coupling that allows muscles to accelerate joints and segments they do not span, and redundant muscle control. Walking requires the successful execution of a number of biomechanical functions such as providing body support, forward propulsion and balance control, with specific muscle groups contributing to their execution. Thus, muscle injury or neurological impairment that affects muscle output can alter the successful execution of these functions and impair walking performance. The loss of balance control in particular can result in falls and subsequent injuries that lead to the loss of mobility and functional independence. Thus, it is important to assess the mechanisms used to control balance in clinical populations using reliable methods with the ultimate goal of improving rehabilitation outcomes. In this review, we highlight common clinical and laboratory-based measures used to assess balance control and their potential limitations, show how these measures have been used to analyze balance in several clinical populations, and consider the translation of specific laboratory-based measures from the research laboratory to the clinic.

Abstract
BACKGROUND This study assessed the effect transcutaneous vagus nerve stimulation (TVNS) for poststroke epilepsy (PSE). METHODS Fifty-two patients with PSE were included in this study. Twenty-seven patients received TVNS, 30 minutes each session, once daily, twice weekly for a total of 4 weeks; and were assigned to the treatment group. Twenty-five patients were at waiting list and were assigned to the control group. The primary outcome included weekly seizure frequency. The secondary outcomes consisted of each seizure episode, and quality of life, measured by the Quality of Life in Epilepsy Inventory-31 (QOLIE-31), as well as the adverse events. All outcomes were measured before and after 4-week treatment. RESULTS After treatment, TVNS failed to show better outcomes in weekly seizure frequency (treatment group, P = .12; control group, P = .56), seizure episode (treatment group, P = .65; control group, P = .92), and QOLIE-31 (treatment group, P = .73; control group, P = .84) compared with these before the treatment. Furthermore, TVNS also did not elaborate the promising effect in seizure frequency (P = .81), seizure episode (P = .75), and QOLIE-31 (P = .33), compared with these in the control group. In addition, minor and acceptable adverse events were recorded in this study. CONCLUSION The results of this study showed that TVNS may be not effective for Chinese patients PSE after 4-week treatment.

Abstract
Depression associated with cerebrovascular disease (CVD) is common among the elderly. Two major types are described, including poststroke depression (PSD), which occurs following a clinically apparent stroke and vascular depression (VaD) which results from silent cerebral infarctions or lacunar infarcts mainly in the subcortical regions. Although PSD and VaD have been regarded as distinctive types of depression, there appears to be a great degree of overlap between them. The case of an elderly patient with late-onset depression is presented to highlight this overlap.

Abstract
BACKGROUND Vibration therapy may be used to help cortical reorganization after stroke as it can cause different adaptive metabolic and mechanical effects. OBJECTIVE This study examined whether the application of mechano-acoustic vibration on upper limb muscles could induce changes in range of motion (ROM), function, pain, and grip strength in individuals with chronic stroke. METHODS Out of 52 individuals post stroke with upper limb spasticity who were eligible,16 received mechano-acoustic vibration therapy (ViSS device) 3 times weekly for 12 sessions. The frequency of vibration was set to 300 Hz for 30 minutes. The treated muscles were the extensor carpi radialis longus and brevis and triceps brachii during voluntary contraction. All participants were evaluated in both upper limbs before (T0) and at the end (T1) of treatment with a dynamometer (hand grip strength), Modified Ashworth Scale, QuickDASH, FIM score, Fugl-Meyer scale, Verbal Numerical Rating Scale of pain, and Jebsen-Taylor Hand Function Test. RESULTS After 4 weeks, hand grip power had improved and pain and spasticity had decreased. Improvements were recorded for all parameters and were considered statistically significant. CONCLUSIONS Application of vibratory stimuli to a muscle can increase the motor-evoked potential recorded from the muscle, suggesting an enhancement of corticospinal excitability. Low amplitude, high-frequency vibration treatment (300 Hz) can significantly decrease tone and pain and improve strength in upper limb of hemiplegic individuals, when applied for 30 minutes, 3 times a week over 4 weeks.

Abstract
This Review describes the current status of poststroke epilepsy (PSE) with an emphasis on poststroke epileptogenesis modeling for testing new therapeutic agents. Stroke is a leading cause of epilepsy in an aging population. Late-onset "epileptic" seizures have been reported in up to 30% cases after stroke. Nevertheless, the overall prevalence of PSE is 2-4%. Rodent models of stroke have contributed to our understanding of the relationship between seizures and the underlying ischemic damage to neurons. To understand whether acutely generated stroke events lead to a chronic phenotype more closely resembling PSE with recurrent seizures, a limited variety of approaches emerged in early 2000s. These limited methods of causing an occlusion in mice and rats show different infarct size and neurological deficits. The most often employed procedure for inducing focal ischemia is the middle cerebral artery occlusion. This mimics the pathophysiology seen in humans in terms of extent of damage to cortex and striatum. Photothrombosis and endothelin-1 models can similarly evoke episodes of ischemic stroke. These models are well suited to studying mechanisms and biomarkers of epileptogenesis or optimizing novel drug discoveries. However, modeling of PSE is tedious, is highly variable, and lacks validity; therefore, it is not widely implemented in epilepsy research. Moreover, the relevance of ischemic models to specific forms of human stroke remains unclear. Stroke modeling in young male rodents lacks clinical relevance to elderly populations and especially to women, likely as a result of sex differences. Nevertheless, because of the neuronal damage and epileptogenic insult that these models trigger, they are helpful tools in studying acquired epilepsy and prophylactic drug therapy. © 2016 Wiley Periodicals, Inc.

Feasibility of lower-limb muscle power training to enhance locomotor function poststroke. ACTA ACUST UNITED AC 2016; 52:77-84. [PMID: 26186176 DOI: 10.1682/jrrd.2014.04.0109] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2014] [Revised: 11/03/2014] [Indexed: 11/05/2022]
Abstract
Poststroke motor control is characterized by greatly reduced muscle power generation. To date, the extent to which muscle power limits walking performance or whether its remediation should be a primary component of locomotor rehabilitation has yet to be established. The purpose of this study was to examine the feasibility and the effects of Poststroke Optimization of Walking using Explosive Resistance training, an intervention aimed at improving poststroke muscular and locomotor function. Twelve subjects (6-60 mo poststroke) participated in 24 training sessions (3 sessions/wk for 8 wk). Exercises included leg press, calf raises, and jump training, all performed at high concentric velocity, as well as trials of fast walking. We measured self-selected and fastest comfortable walking speeds as well as knee extensor and plantar flexor strength and power at pretraining, posttraining, and 8 wk follow-up time points. In addition, we also performed a number of clinical assessments commonly used in poststroke rehabilitation trials. Following training, significant improvements in lower-limb muscle strength and power were realized and accompanied by improvements in self-selected as well as fastest comfortable walking speeds. No changes in clinical assessments resulted from training.

Abstract
BACKGROUND Quality of life (QOL) measures are effective in quantifying disease burden after stroke, more so than levels of debility. The objective of this study is to determine QOL and associated factors of stroke survivors in Lagos, Nigeria. MATERIALS AND METHODS Seventy stroke survivors (study sample) and seventy stable hypertensive patients (control sample) attending clinics at a Nigerian hospital were recruited for the study. Respondents were assessed using sociodemographic/clinical questionnaires, modified mini-mental state examination, modified Rankin Scale, schedule for clinical assessment in neuropsychiatry, and World Health Organization-QOL-BREF. RESULTS Mean ages of the study and control respondents were 57.43 (±9.67) years and 57.33 (±9.33) years, respectively. Each sample comprised 38 male and 32 female respondents. Stroke survivors were significantly more likely to: be unemployed (P = 0.001), pay more for healthcare (P = 0.001), consume alcohol (P = 0.02), and have physical impairments (P = 0.001) compared with control. The mean QOL scores of stroke survivors were significantly lower than controls across all spheres. Stroke survivors who were unemployed, younger, female, paying more for healthcare, more disabled, with right stroke lateralization, having comorbidities, and sexual dysfunction had significantly poorer QOL specific grades. Depression or anxiety poststroke was also associated with reduced QOL means scores. CONCLUSION Besides, clinical variables such as levels of disability and stroke lesion lateralization, other factors such as unemployment, health costs, age, gender, and emotional problems influenced QOL after stroke.

Acute Onset Dystonia after Infarction of Premotor and Supplementary Motor Cortex. J Stroke Cerebrovasc Dis 2015; 24:2880-2. [PMID: 26483154 DOI: 10.1016/j.jstrokecerebrovasdis.2015.09.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2015] [Revised: 09/10/2015] [Accepted: 09/17/2015] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE Poststroke dystonia is the second most common movement disorder after chorea and often has a delayed manifestation. Lesions of the contralateral lenticular nucleus, particularly the putamen, have been implicated in the pathogenesis of dystonia. We present an unusual case of rapid onset of focal dystonia of the left upper extremity, which developed after infarction of the right premotor cortex (PMC) and the supplementary motor area (SMA). METHOD A retrospective chart review of the patient was performed. RESULTS AND CONCLUSION We propose that disruption of the afferents from PMC and SMA in the setting of chronic striatal abnormality can result in acute dystonia due to disinhibition of the thalamocortical circuit.

Abstract
Context: Poststroke care in developing countries is inundated with poor concordance and scarce specialist stroke care providers. A primary care-driven health service is an option to ensure optimal care to poststroke patients residing at home in the community. Aims: We assessed outcomes of a pilot long-term stroke care clinic which combined secondary prevention and rehabilitation at community level. Settings and Design: A prospective observational study of stroke patients treated between 2008 and 2010 at a primary care teaching facility. Subjects and Methods: Analysis of patients was done at initial contact and at 1-year post treatment. Clinical outcomes included stroke risk factor(s) control, depression according to Patient Health Questionnaire (PHQ9), and level of independence using Barthel Index (BI). Statistical Analysis Used: Differences in means between baseline and post treatment were compared using paired t-tests or Wilcoxon-signed rank test. Significance level was set at 0.05. Results: Ninety-one patients were analyzed. Their mean age was 62.9 [standard deviation (SD) 10.9] years, mean stroke episodes were 1.30 (SD 0.5). The median interval between acute stroke and first contact with the clinic 4.0 (interquartile range 9.0) months. Mean systolic blood pressure decreased by 9.7 mmHg (t = 2.79, P = 0.007), while mean diastolic blood pressure remained unchanged at 80mmHg (z = 1.87, P = 0.06). Neurorehabilitation treatment was given to 84.6% of the patients. Median BI increased from 81 (range: 2−100) to 90.5 (range: 27−100) (Z = 2.34, P = 0.01). Median PHQ9 scores decreased from 4.0 (range: 0−22) to 3.0 (range: 0−19) though the change was not significant (Z= −0.744, P = 0.457). Conclusions: Primary care-driven long-term stroke care services yield favorable outcomes for blood pressure control and functional level.

Spatial and temporal asymmetries in gait predict split-belt adaptation behavior in stroke. Neurorehabil Neural Repair 2013; 28:230-40.

Abstract
BACKGROUND Step asymmetries during gait in persons after stroke can occur in temporal or spatial domains. Prior studies have shown that split-belt locomotor adaptation can temporarily mitigate these asymmetries. OBJECTIVE . We investigated whether baseline gait asymmetries affected how patients adapt and store new walking patterns. METHODS Subjects with stroke and age-matched controls were studied walking at a 2:1 speed ratio on the split-belt during adaptation and assessed for retention of the learned pattern (the after-effect) with both belts at the same speed. RESULTS Those with stroke adapted more slowly (P < .0001), though just as much as healthy older adults. During split-belt walking, the participants with stroke adapted toward their baseline asymmetry (eg, F = 14.02, P < .01 for step symmetry), regardless of whether the subsequent after-effects improved or worsened their baseline step asymmetries. No correlation was found between baseline spatial and temporal measures of asymmetry (P = .38). Last, the initial spatial and temporal asymmetries predicted after-effects independently of one another. The after-effects in the spatial domain (ie, center of oscillation difference) are only predicted by center of oscillation difference baseline (F = 15.3, P = .001), while all other parameters were nonsignificant (all Ps > .17). Temporal coordination (ie, phasing) after-effects showed a significant effect only from phasing baseline (F = 26.92, P < .001, all others P > .33). CONCLUSION This work demonstrates that stroke patients adapt toward their baseline temporal and spatial asymmetries of walking independently of one another. We define how a given split-belt training session would affect asymmetries in these domains, which must be considered when developing rehabilitation interventions for stroke patients.

Comparison between pharmacologic evaluation and repetitive transcranial magnetic stimulation-induced analgesia in poststroke pain patients. Neuromodulation 2013; 16:349-54; discussion 354. [PMID: 23311356 DOI: 10.1111/ner.12019] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2012] [Revised: 11/05/2012] [Accepted: 11/25/2012] [Indexed: 01/16/2023]
Abstract
BACKGROUND It has been reported that poststroke pain has a complex pharmacologic background and that only about one-half of poststroke pain patients are sensitive to motor cortex stimulation induced by repetitive transcranial magnetic stimulation (rTMS). OBJECTIVES The relationship between pharmacologic background and effects of rTMS of the primary motor cortex was investigated to clarify the pharmacologic basis of rTMS-induced analgesia in poststroke pain patients. METHODS Changes in visual analog scale (VAS) score for pain following drug challenge tests using ketamine, morphine, and thiopental were compared with the changes in VAS score following rTMS of the primary motor cortex (frequency 5 Hz, at 100% resting motor threshold, 500 pulses per session) in 20 poststroke pain patients. RESULTS In our drug challenge test, 10 of 20 (50%) patients in ketamine test, 7 of 20 (35%) in thiopental test, and 3 of 20 (15%) in morphine test showed more than 40% reduction of VAS score. VAS score decreased immediately after rTMS of motor cortex and persisted for 300 min (p < 0.05, Bonferroni's multiple comparisons). Comparison of the magnitude of VAS score reduction between drug challenge test and rTMS showed significant correlations with ketamine test (r = 0.503, p = 0.012), morphine test (r = 0.526, p = 0.009), and thiopental test (r = 0.609, p = 0.002) by regression analysis. CONCLUSIONS rTMS-induced VAS score reduction correlated well with morphine, ketamine, and thiopental tests. However, ketamine sensitivity was observed in more cases compared with morphine and thiopental in poststroke pain patients. We speculate that additional pharmacologic therapy using ketamine as determined on the basis of the ketamine test may be useful for enhancing the efficacy of rTMS in poststroke pain patients.

Abstract
Poststroke depression (PSD) in elderly patients has been considered the most common neuropsychiatric consequence of stroke up to 6-24 months after stroke onset. When depression appears within days after stroke onset, it is likely to remit, whereas depression at 3 months is likely to be sustained for 1 year. One of the major problems posed by elderly stroke patients is how to identify and optimally manage PSD. This review provides insight to identification and management of depression in elderly stroke patients. Depression following stroke is less likely to include dysphoria and more likely characterized by vegetative signs and symptoms compared with other forms of late-life depression, and clinicians should rely more on nonsomatic symptoms rather than somatic symptoms. Evaluation and diagnosis of depression among elderly stroke patients are more complex due to vague symptoms of depression, overlapping signs and symptoms of stroke and depression, lack of properly trained health care personnel, and insufficient assessment tools for proper diagnosis. Major goals of treatment are to reduce depressive symptoms, improve mood and quality of life, and reduce the risk of medical complications including relapse. Antidepressants (ADs) are generally not indicated in mild forms because the balance of benefit and risk is not satisfactory in elderly stroke patients. Selective serotonin reuptake inhibitors are the first choice of PSD treatment in elderly patients due to their lower potential for drug interaction and side effects, which are more common with tricyclic ADs. Recently, stimulant medications have emerged as promising new therapeutic interventions for PSD and are now the subject of rigorous clinical trials. Cognitive behavioral therapy can also be useful, and electroconvulsive therapy is available for patients with severe refractory PSD.
