In France, more than 110.000 patients are hospitalized for stroke per year. It is the leading cause of sudden disabilities in adults. Incidence of spastic foot is evaluated at 1 year post stroke from 18% to 56% of hemiplegic patients. Spasticity, defined as an increase in the velocity-dependent response to muscle stretch measured at rest, is part of the upper motor neuron syndrome and is characterized by an increase in tonic stretch reflex. It has been proposed that upper motor neuro syndrome may induce not only spasticity but also other types of muscles overactivity such as spastic dystonia, co-contraction and clonus. In hemiplegic patients, lower limb spasticity within the posterior part of the leg frequently results in equino-varus foot and toes claw. These abnormal postures in hemiplegics may affect activities of daily living such as shoes fitting, balance, ambulation-walking, comfort (pain) and may become irreducible (tendon shortening) if not treated. The purpose of this study is to compare the interest of each treatment (BoNT-A versus STN) in order to specify both techniques indications and up-date current guidelines of lower-limb spasticity for hemiplegic patients. This study aims to confirm a greater reduction of calf muscles spasticity after STN as compared to BoNT-A, as observed in the only published monocentric randomized controlled trial. Our study originality is to perform a multi-center RCT with a pre-established sample size. This study will also quantify progress towards personal goals using the goal attainment scaling (GAS) and will assess other components related to the consequences of carve muscle spasticity on balance, ambulation, self-care and quality of life.
Following a right stroke, more than half of the patients present a communication disorder. These disorders can notably concern prosody. Nevertheless, these remain relatively poorly assessed and characterized. Prosodic alterations in comprehension can result in a disruption of social cognition with potentially important consequences in terms of functional outcome and quality of life of patients. In clinical practice, the investigators do not have a tool that allows us to finely assess these disorders. Studies in healthy subjects using a processing algorithm capable of arbitrarily manipulating the pitch dynamics of recorded voices have revealed that there are stable internal representations for prosody processing. Initial pilot results show that this method can be used in a clinical context and can indeed identify and accurately measure perceptual processing deficits in prosody following a right stroke. It is necessary to continue the study of this approach with a larger number of subjects in order to have normative data and validate the diagnostic properties of this approach.
Evidence suggests that oxytocin has a neuroprotective role on a systemic and cellular level in the context of acute ischemic stroke (AIS). The investigators therefore hypothesize that high levels of circulating oxytocin measured within the first 72 hours after symptom onset are associated with lower mortality and favorable outcome in acute ischemic stroke.
The purpose of this cross-sectional study is to translate and cross-culturally adapt to Spanish the Motor Evaluation Scale for Upper Extremity in Stroke Patients (MESUPES) and the Stroke Upper Limb Capacity Scale (SULCS) and to assess their psychometric properties in Spanish people with chronic stroke.
This study aims to investigate the relationship between multifidus and gastrocnemius muscle thickness with postural stability in patients with stroke.
Introduction Remote cerebral hemorrhage following reperfusion treatment in ischemic stroke is rare (1.3-3.7% of all treated strokes) and is associated with worse functional and vital prognosis. Multicenter observational studies suggest that amyloid angiopathy may be one of the main risk factors for remote hemorrhage. Currently, it is unknown what happens to those patients with remote hemorrhage beyond 3 months of follow-up in terms of risk/benefit balance when receiving antiplatelet or anticoagulant therapy, as well as from a cognitive point of view. Considering an analogy with amyloid angiopathy, the hypothesis is that those patients with remote hemorrhage have a higher risk of intracranial hemorrhage during follow-up when receiving stroke secondary prevention, and will also present greater cognitive deterioration during long-term follow-up. Main Objectives - To explore the frequency and risk factors for intracranial hemorrhage during follow-up of patients with remote cerebral hemorrhage. - To explore the frequency and progression of cognitive deterioration during follow-up in patients with remote cerebral hemorrhage. Methodology Observational, prospective, multicenter registry with a population-based case-control design of consecutive patients with remote hemorrhage following reperfusion therapy in acute ischemic stroke. Inclusion criteria: Diagnosis of ischemic stroke with age greater than or equal to 18 years who has remote cerebral hemorrhage after receiving reperfusion therapy in the acute phase. Exclusion criteria: Lack of basic data (age, sex, neuroimaging data) or telephone for follow-up. The cases will be those patients with remote hemorrhage. For each case included, 4 consecutive controls will be included (2 with local parenchymal hemorrhagic transformation and 2 without hemorrhagic transformation). The data will be filled out within the (Codi Ictus de CATalunya) CICAT registry form (currently mandatory in all stroke centers in Catalonia) to which additional variables will be added. Telephone follow-up will be conducted at 3, 12, and 24 months. Main study variable: - Any type of spontaneous or traumatic intracranial hemorrhage during a 24-month follow-up. - Score on the "Short Informant Questionnaire" scale (a validated 17-question questionnaire to be conducted over the phone, where a score higher than 57 points indicates cognitive impairment). Expected sample size during a 2-year recruitment period: 105-300 patients (considering the participating centers to date). Additional information. This study is endorsed by the "Pla Director de la Malaltia Vascular Cerebral" in Catalonia. Participating Centers. Participation offers have been sent to the 28 hospitals in the hospital network of Catalonia with the capacity to administer intravenous fibrinolysis. Positive responses have been received from 13 of them so far. In case the project is accepted by the (Comité Ético de Investigación Clínica) CEIC Sant Pau, the centers that have not responded will be contacted again to obtain their participation.
Hypothesis: Hyper chloremia is associated with poor outcome in Intracerebral Hemorrhage (ICT). Hyperchloremia is defined as serum chloride level of 110mmol/L or greater. This clinical study is assuming that, by increasing the ratio of Sodium-acetate to Sodium-chloride solutions in IV treatment, the incidence of Hyperchloremia can be lowered significantly. This result can be demonstrated by measuring serum chloride levels at Baseline, 24Hr, 48Hr and 72 Hours' time intervals and compare them between the three treatment and one Control arm. Intervention (drug/biologic/device/behavioral): Phase 2-dose finding Patients will be enrolled in the study and randomized into one of the four study treatment arms(target fluid administration rate 1 ml/kg/hour) initiated within 12 hours. IVF will be prepared in the main hospital pharmacy. 1. Sodium chloride (0.9%) referred as 0.9% NaCl for 72 hours post symptom onset (60-72 hourspost randomization); 2. Sodium chloride (0.9%) and sodium acetate (0.9%) mixture 3:1 ratio for 72 hours post symptom onset (60-72 hours post randomization); 3. Sodium chloride (0.9%) and sodium acetate (0.9%) mixture 2:1 ratio for 72 hours post symptom onset (60-72 hours post randomization); 4. Sodium chloride (0.9%) and sodium acetate (0.9%) mixture 1:1 ratio for 72 hours post symptom onset (60-72 hours post randomization).
Sleep difficulties are common following stroke yet effective evidence-based interventions for improving sleep in this population are lacking. A small number of studies have investigated the use of music listening as a way to improve sleep in adults with insomnia. This study aims to examine whether a mindful music-listening intervention can reduce subjective and objective insomnia symptoms and improve mood and fatigue post-stroke. Six adults with a clinical diagnosis of stroke presenting with an insomnia disorder will be recruited from stroke services within NHS Greater Glasgow and Clyde. A multiple baseline single case experimental design will be employed. Participants will be randomly allocated to a baseline phase of 7, 11 or 15 days, followed by a five-week mindful music-listening intervention incorporating sleep hygiene. Changes in subjective and objective sleep will be measured using questionnaires and actigraphy, respectively. Mood and fatigue will also be measured. The data will be analysed using visual inspection, Tau-U and multi-level modelling.
After a stroke, it is very common to lose the ability to open the affected hand. Occupational and physical rehabilitation therapy (OT and PT) combined with non-invasive brain stimulation may help a person recover hand movement. The purpose of this study is to compare 3 non-invasive brain stimulation protocols combined with therapy to see if they result in different amounts of recovery of hand movement after a stroke.
