Filter by:The study will focus on the impact of communal singing on patients with stroke and their personal caregivers. Forty post-stroke patients will be randomly assigned to two groups: the first group of 20 stroke survivors and their caregivers (up to 40 total participants) will receive 6 months (approximately 24 sessions) of music therapy. The second control groups of 20 stroke survivors and their caregivers will receive standard post-stroke care
The purpose of this study is to provide a description of blood flow changes in the brain after blood pressure lowering drugs are given. This information will be used by physicians to guide blood pressure lowering therapy in stroke patients in the future.
The goal of this project is to test a device (Zondervan et al, 2013) that can provide active assistance for arm training for people in Vietnam with severe to moderate stroke, but that is also simple and does not rely on powered actuators. The hypothesis is that individuals with a severe chronic stroke, who exercise with a mechanically passive rehabilitation device, will have improved arm movement ability without experiencing an increase in arm pain.
Ischemic stroke, i.e. irreversible damage of a part of the patient's brain, is caused by the formation of blood clot in the major vessel which gives blood supply to a certain part of the brain. At early time, within the first 4,5 hours, the conventional treatment is to try to dissolve this blood clot with a medication ("thrombolytic drug") which is administered to the blood through the needle in the vein. If the clot still remains there, additional treatment is possible - going directly to the clot via artery and taking it out with a special device. Patients may be included even if they are not treated with intravenous thrombolysis because of contraindication or other reasons. The purpose of the present study is to evaluate the benefit and safety efficacy of thrombectomy and standard stroke care in clinical routine treatment of acute occlusive stroke compared to standard stroke care only.
This study is to investigate changes in brain activities in acute stroke patients , and to correlate findings with clinical outcome measures. Another aim of the study is to investigate whether transcranial direct current stimulation (tDCS) could improve motor function in subjects with poor brain activity after stroke. The brain activity will be measured by single and paired pulse TMS (transcranial magnetic stimulation). The study hypothesizes that: 1. The neural mechanisms employed in patients who have different response to TMS stimulation are different. It is hypothesized that patients with no response upon TMS stimulation might have poorer motor function outcome, compared with patients with response upon TMS stimulation. 2. The result of clinical outcome measures is related with TMS measurement. 3. tDCS intervention is beneficial to subjects with poor brain activity. Clinical outcome measures will include a battery of upper limb motor tests such as upper extremity component of the Fugl-Meyer Assessment, Modified Ashworth scale for spasticity, box and block test, and manual muscle testing. Clinical outcome and TMS measurement will be assessed at within 2 weeks, 4-6 weeks and at 6 months post-stroke.
The purpose of this study is to determine whether acupuncture and computer-based attention training can be combined for more effective post-stroke attentional deficits.
Stroke is the largest cause of adult disability in the United Kingdom. Loss of hand function, muscle weakness, pain, and joint deformities are persistent and disabling problems for nearly half of all stroke survivors. This can, in part, result from patients not getting adequate therapy targeting the hand and arm in the very early stages of rehabilitation. Previous research has highlighted the importance of early rehabilitation interventions after stroke. Although in stroke patients the damage is to the brain rather than the limbs, muscle wastage (atrophy) can occur soon after stroke through non-use. Muscle atrophy can even occur in those who have retained some degree of active arm movement. Electrical stimulation (ES) is a painless treatment in which small pulses of electrical current from a battery operated portable device are used to activate a paralysed muscle and produce a strong muscle contraction. ES has been shown to increase brain activity and can hence influence the formation of new nerve pathways (known as neuroplasticity) to replace those damaged by stroke. Previous studies have concluded that six weeks of ES to the muscle on the back of the forearm improved the chance of a person recovering arm function. However, as the intensity of treatment was not sufficient to prevent the complications identified in this proposal, the impact of any functional benefit was significantly limited. We plan to build on previous research by training clinical therapists to operate ES devices; starting ES much earlier after stroke; applying a higher intensity treatment to more of the forearm muscles (i.e. both the front and back of the forearm) and providing treatment for a longer period of time than previously carried out. We will evaluate the feasibility of incorporating ES into a patient self-management programme to enable independent use outside of routine therapist led rehabilitation sessions.
The purpose of this study is to evaluate the protective effects of upper limb ischemic postconditioning on collateral circulationin young symptomatic intracranial atherosclerosis and the baseline characteristics of trial participants, as an open, randomized controlled, prospective controlled trial.
In this project we will design a control algorithm to identify the focalized motor-related clusters for hand function on each stroke patient. A real-time feedback will control the robotic hand when motor imagery is successfully identified. Finally, the focalized BCI-robot training will be compared in a randomized controlled trial to evaluate the training effectiveness and changes in the EEG patterns.
A BCI system for stroke subjects will be designed in an attempt to train the motor-related areas in their brains responsible for hand open/close function. A robot hand will be used and controlled by the system in real time based on EEG pattern for identification of motion intention for hand movements in the motor cortex. A randomized controlled trial study design will be adopted. All subjects will be assessed by clinical assessments including FMA and neuroimaging assessments using multimodal MR techniques before and after the training to evaluate training effectiveness.
