Filter by:Claw toes deformity result in spasticity often seem in patients with central nerve disease. It also cause pressure sore in foot and pain during walking that didn't well improve under traditional treatment. There are few relative reports about the Botulinum toxin type A (BTX-A) injection on claw toe. The investigators' study has two main purposes: 1. assess the efficiency of BTX-A injection under ultrasonographyic guidance on improving lower extremities function, pain and spasticity in patients with symptomatic claw toes. 2. assess if regular stretching exercise can strength the efficiency of BTX-A injection on improving lower extremities function, pain and spasticity.
The purpose of this study is to determine whether intensive, focused training of the affected upper extremity after stroke results in long-term functional gains in moderately-to-severely paralyzed patients, more than 6 months after their vascular accident. During the course of therapy, user's attempts to move and complete exercises are assisted by neuromuscular electrical stimulation.
The aims of this study were to compare the injection locations of key spastic muscles on upper extremity by three different guidance localization methods ( surface anatomy landmark, ultrasonography, electric stimulation) and the effectiveness.
The aim of this study: 1. To evaluate the correlation between the clinic tools and ultrasound elastography/ ARFI imaging in stroke patients. 2. To assess the reliability of elastography/ ARFI imaging in spasticity evaluation of stroke patients.
The purpose of the research is to understand structural plaque abnormalities that make a carotid plaque unstable and brake off (embolize) which would help to predict and treat individuals who are likely to suffer not only classic episodic major strokes but also cognitive impairment.
Stroke may result in lower extremity spasticity, which interfere with motor voluntary function and activities of daily living. Botulinum toxin type A (BTX-A) has been shown to improve lower extremity spasticity of stroke patients. There are no researches to compare the efficiency of BTX-A injection by different guidance methods in the deep muscles of lower extremity for stroke patients. The aims of investigator's study were to compare the effectiveness of BTX-A injection by different guidance methods (palpation of anatomical landmarks, ultrasonography direct) in deep spastic muscles of lower extremity for stroke patients with varus spasticity and spastic claw toes , and to study the correlation between muscles spasticity and elastic properties by the sonoelastography/acoustic radiation force impulse imaging and follow the change of elastic properties in spastic muscles after BTX-A injection. We will enroll 80 hemiplegic stroke patients with varus spasticity / spastic claw toes and duration more than 6 months. Under different guidance methods (palpation of anatomical landmarks, electric stimulation, ultrasonography direct and indirect methods), BTX-A will be injected to the flexor digitorum longus and posterior tibialis muscles. If the patients have moderate hallucis spasticity, flexor hallucis longus muscle will be injected. The BTX-A dose is 50 units for each muscle. Outcome measures include Modified Ashworth Scale, Brunnstrom stage, muscle power, range of motion, the visual analog scale of pain, Stroke Impact Scale, Barthel index and lower extremity function tests, balance test, Goal Attainment Scale, sonoelastography and acoustic radiation force impulse imaging. All the assessments will be performed before BTX-A injection and followed up at 1 months, 2 months, 3 months and 6 months after injection. After performing all the assessments, investigator will investigate the efficiency of BTX-A by different guidance methods.
The purpose of this study is to evaluate the efficacy and safety of 5mg maintenance dose (MD) of prasugrel in patients with acute myocardial infarction (AMI) who underwent percutaneous coronary intervention (PCI) with BiomatrixTM stent.
The cerebrovascular accident (CVA) is currently the leading cause of death in Brazil and it is estimated that there are about 62 million stroke survivors worldwide. Thus, the stroke sequels are a major public health problem not only in Brazil but in the world, with existing treatments often insufficient for complete recovery. Thus this study aims to identify predictors of different responses from rehabilitation therapy through the evaluation of clinical and neurophysiological data performed before and after treatment. For the neurophysiological study will be used the association of electroencephalogram (EEG) and transcranial magnetic stimulation (TMS). This last one will be performed in the baseline and after a single Transcranial direct current stimulation (tDCS) session, aiming to leverage the ability of those technics to analyze the cerebral plasticity. As a secondary objective: 1) Identify specific features of brain plasticity involved in recovery from stroke and discuss the possible implications of these findings in the therapeutic approach; 2) Search possible electrophysiological markers that can be used as surrogate outcome of stroke of motor sequel.
The investigators are trying to determine the therapeutic effect of the music glove and conventional hand exercise program to the subacute stroke patients. All participants will be randomized into two groups: AB and BA. They will all exercise at least 3 times a week for 3 weeks with a minimal 3 hours exercise time per week. Participants will receive the other intervention at 3-month post stroke date. Clinical evaluations will be performed at baseline, post therapy after first intervention, 3-week post intervention follow up, 3-month post stroke, post therapy after second intervention, 3-week post second intervention follow up, and 6-month post stroke follow up visits.
