Filter by:Balance disorders are very common after strokes and often last for long periods of time. Their origin is multifactorial and their impact on the daily lives of patients are particularly important, especially on gait. The vibration technology for rehabilitation was already studied in static posture with force plats but their impact on gait have yet to be evaluated. This present study aims at investigating the effects of vibrations applied by an approved medical device to the posterior neck muscles and the gluteus medius - major actors of proprioception and posture mechanisms - on gait disorders in patients with hemiplegia during the chronic phase after stroke.
The main objective of the present study was to compare the effects of exoskeleton devices used in electromechanical-assisted gait training after stroke compared to over ground conventional physical therapy in a single blind research. The second objective is to research when the devices can be used with the best chance of success in the functional recovery of gait in people who are unable to walk independently after stroke.
Impaired speech production is a major obstacle to full participation in life roles by stroke survivors with aphasia and apraxia of speech. The proposed study will demonstrate the short-term effects of auditory masking on speech disfluencies and identify individual factors that predict a positive response, enabling future work to develop auditory masking as a treatment adjuvant targeting long-term improvement in speech. Providing an additional treatment option for adults with aphasia and apraxia of speech will have the clear benefit of improving quality of life and allowing individuals to participate more actively in their health care decisions through improved communication.
Stroke patients are given prophylactic treatment with clopidogrel to prevent new strokes. Some of these patients (the investigators don't know precisely how many, but previous studies indicate 4-34%) are so called non-responders, when you measure on a blood sample from the patient. These patients may have an increased risk for less effect of the treatment and therefore a higher risk for a new stroke. The investigators want to investigate if clopidogrel non-responders have a clinically increased risk of a new stroke by following the patients for two years. With this study the investigators aim to ensure that all patients get the best prophylactic treatment and reduce the risk of early death and dependency of others.
The purpose of this study is to evaluate by objective measures the improvement in upper extremity functioning, as reflection of motor learning, in stroke patients in the sub acute phase. The investigators hypothesize that the improvements in daily functioning are partially due to compensation strategies and partially due to motor learning.
The study is a large scale cluster randomised trial to evaluate the effects of sodium reduction based upon the use of salt substitute on the risk of stroke defined as the occurrence of stroke and stroke deaths. The corresponding null hypothesis that will be tested is that sodium reduction will have no effect upon stroke risk. The secondary objectives are to determine effects of sodium reduction on major vascular events and total mortality.
Background: To study intensive targeted cognitive rehabilitation of attention in the acute (<4 months) and subacute rehabilitation phases (4 -12 months) after acquired brain injury and to evaluate the effects on function, activity and participation (return to work). Design: prospective, randomised, controlled study. Methods: 120 consecutive patients with stroke or traumatic brain injury are randomised to 20 hours of intensive attention training by Attention Process Training or by standard, activity based training. Progress is evaluated by Statistical Process Control and by pre and post measurement of functional and activity levels. Return to work is also evaluated in the post-acute phase. Primary endpoints are the changes in the attention measure, Paced Auditory Serial Addition Test and changes in work ability. Secondary endpoints include measurement of cognitive functions, activity and work return. There are 3, 6 and 12-month follow ups focussing on health economics. Discussion: The study will provide information on rehabilitation of attention in the early phases after acquired brain injury (ABI); effects on function, activity and return to work. Further, the application of Statistical Process Control might enable closer investigation of the cognitive changes after acquired brain injury and demonstrate the usefulness of process measures in rehabilitation.
The purpose of this study is to prospectively examine the relation between ischemic stroke and hair cortisol concentration. The investigators hypothesize that patients with ischemic stroke have higher levels of hair cortisol compared to controls.
Dysphagia is one of severe complications among stroke survivors. Dysphagia is usually associated with high levels of morbidity, mortality, and financial cost. In recent years, repetitive transcranial magnetic stimulation (rTMS) has shown promise to facilitate poststroke dysphagia. However, most researches were preliminary studies in the past. The present study aims to investigate the immediate and long-term efficacy of high frequency rTMS on chronic dysphagic patients.
Background: - People can learn to use feedback about brain activity to change that activity. Researchers want to see if people who have had a stroke can change their brain activity by practice and thought with feedback, and if that improves motor control. They will study brain activity in people who have and have not had strokes. Objectives: - To see if people with stroke can change their brain activity and improve motor control by practice and thought. Eligibility: - Adults 18 80 years old who have had a stroke. - Healthy volunteers 18 80 years old. Design: - Participants will be screened with a medical history, MRI, and physical exam. For MRI, a magnetic field and radio waves take pictures of the brain. Participants lie on a table that slides in and out of a cylinder. They will be in the scanner less than 2 hours, lying still for up to 15 minutes at a time. The scanner makes loud noises. Participants will get earplugs. - Participants will have up to 3 scanning visits and up to 3 follow-up visits within 24 weeks. Visits may include screening, MRI, functional MRI (fMRI), questionnaires, and simple motor tests. Stroke participants may take additional motor tests, including transcranial magnetic stimulation (TMS). - fMRI: During this MRI, small metal disks may be taped to the skin or a fabric glove with small wires in it may be used to monitor hand movements. Heart rate and breathing may also be monitored. Participants may be monitored by video and asked to perform tasks. - TMS: A brief electrical current goes through a coil on the scalp. It creates a magnetic pulse that stimulates the brain. Participants may be asked to perform simple actions. Finger or hand movements may be recorded.
