Introduction The motor impairment of the upper extremity is the most common sequelae after ischemic stroke. Transcranial magnetic stimulation (TMS) is a promising non- invasive technique in the rehabilitation of motor deficits. However, its effect in post-stroke motor deficits remains moderate our days. To potentiate the effect of TMS, techniques called Paired Associative Stimulations (PAS) involving the integration of afferent sensory inputs at the level of the ipsilesional primary motor cortex were developed in healthy subjects. PAS techniques have shown a gain of corticospinal excitability by such phenomenon known as long Term Potentiation (LTP) and a gain of motor performance. The investigators would like to propose to evaluate two types of these techniques with a volley of visual afferents (visuomotor stimulation, V_PAS) or of cerebellar afferents (CER_PAS), because these two structures convey important information in the execution of the movement. Design Multicenter, randomized, study, 60 patients in 3 parallel groups (V_PAS, CER_PAS, control group with sham and sham V_PAS CER_PAS), 5 days of treatment, clinical assessment, electrophysiological and MRI before, immediately post- and second post-assessments (4 weeks). A group of 24 healthy subjects will undergo a parallel physiopathological study on the underlying mechanisms of cerebellar PAS Objectives Main objective: To determine whether (and how) Paired Associative Stimulation technique (PAS) induces cerebral reorganization in the primary motor cortex compared to the control group. Aim 2: Determine whether (and which) type of PAS is capable of inducing changes in motor performance of the upper limb paresis and duration Aim 3: Determine whether (and which) type of PAS is capable of inducing changes in excitability of the corticospinal tract and duration Aim 4: Determine how PAS techniques modify the functional connectivity during movement Aim 5: Determine if connectivity changes during induced movement correlate with clinical improvements Aim 6: Determine whether patients who benefit of a type of PAS have specific anatomical lesion characteristics (volume, afferent and efferent white matter fasciculi integrity)
The purpose of this study is to evaluate if Apixaban will decrease the complication of having another stroke for people who have atrial fibrillation if initiated earlier than standard of care.
The purpose of this study is to determine the feasibility of performing a randomized controlled trial to investigate the efficacy of an anti-inflammatory drug, colchicine, at reducing well validated markers of thrombosis (D-dimer) and inflammation (hs-CRP).
Individuals older than 60 years old, discharged after suffering brain stroke with referral to the rehabilitation outpatient clinic, will be assessed for orthostatic balance. Patients with positive Romberg test are invited to participate in the trial. Participants will be randomized to either the current rehabilitation protocol or to an supplemental intervention focused on oculomotor and gaze stability exercises to be applied at home for three weeks. Participants will be assessed with standardized, validated tools.
This is a multicenter, double-blind, randomized, placebo-controlled study designed to compare Botulinum Toxin Type A for Injection (HengLi®) with placebo on the efficacy and safety of treatment in post-stroke subjects with focal wrist, finger and in some cases, thumb spasticity. Approximately 180 subjects will be enrolled. The core period of the subjects will receive a single treatment session of intramuscular HengLi® 200U or 240U (if thumb spasticity is present) or placebo in a randomization ratio of 2:1. Research contains two parts: core phase and extension phase. In the core phase, subjects will finish 6 visits (12 weeks ) after initial injection. During the extension phase, subjects will accept two follow-up visit (6 weeks). Outcome measures include changes from baseline at every post injection visit as measured on the Modified Ashworth Scale (MAS), Disability Assessment Scale (DAS) and Global Assessment Scale(GAS). The primary efficacy endpoint is the change from baseline at week 6 for wrist flexor muscle tone as measured on the Modified Ashworth Scale. Safety parameters will also be measured including adverse events, vital signs (pulse and blood pressure) and clinical laboratory tests (haematology, serum chemistry and urinanalysis).
Atrial fibrillation is a common cardiac arrhythmia and a major risk for ischemic stroke. Furthermore the risk of stroke is higher in the first month after transient ischemic attack (TIA)/stroke. Rivaroxaban has been approved by Health Canada over period of last two years for prevention of stroke and have been found equally effective as oral Vitamin K antagonist. The foremost benefits of NOAC are reduced intracranial bleeding risk and does not require coagulation monitoring. Optimal timing of anticoagulation after TIA/stroke in patients with known non-valvular atrial fibrillation is not known. The practice is variable and opinion based. The bias for many stroke physicians and neurologists is to start later (after 1-2weeks) to prevent hemorrhagic transformation thus possibly exposing the patients to an increased risk of recurrence. The product monograph for the drug suggest to wait for variable of 3 to 14 days before starting the NOAC (Waiting period:14 days for dabigatran and rivaroxaban, 7 days for Apixaban after ischemic stroke and three days after TIA for rivaroxaban). The times have been chosen arbitrary. The investigators aim to study incidence of symptomatic hemorrhage in patients with non-valvular atrial fibrillation who are initiated with new oral anticoagulants early after TIA and stroke.
Stroke patients frequently necessitate walking aids such as 4-point canne. However, the 4-point canne has to be lifted by the patient which limited gait speed. The adjunction of small wheel below the 4 point of the canne (4-roll) gives the possibility to the patient to walk without having to lift the canne as it will roll over the ground. The aim of our study is to compare gait parameters (gait speed and energy cost) with a classical 4-point canne and with 4-roll canne.
The aim of the study is to evaluate the analgesic effects of navigated repetitive transcranial magnetic stimulation in central post stroke pain. MRI based navigation is used to determine the exact locations for stimulation.
Individuals who have sustained a stroke are often left with residual deficits of the upper limb such as impaired movement and sensation. These deficits restrict functional use of the limb in everyday activities and can result in increased dependency upon others to engage in some tasks. Regaining independence through functional use of the arm and hand is an aim of occupational therapy rehabilitation. Mirror box therapy (MBT) is a relatively new innovation being introduced into occupational therapy interventions. Some studies have reported it to be beneficial in upper limb rehabilitation, however, these studies have not involved a sub-acute stroke population. This pilot study aims to provide robust evidence, using RCT design, as to whether this type of therapy may offer greater potential in functional gains in the sub-acute recovery period of stroke than standard rehabilitation of the upper limb alone.
