Filter by:This study investigates if transcranial Direct Current Stimulation (tDCS) is effective in the recovery of postural control in stroke rehabilitation.
Recruited patients should receive the endoscopic surgery for picking the olfactory mucosa 1 to 2 months before transplantation. The Olfactory Ensheathing Cells (OECs) will be cultured and expanded under the rule of GTP. Then, quality control of OECs should be done by immunohistochemical staining positive for GFAP, S100, and P75. Finally, the investigators will transplant the OECs (about 2 to 8 X 10´6 cells in saline) into the peri-infarcted area of the brain.
Stroke is the leading cause of disability in the United States. One of the reasons that it is so disabling is because of upper extremity hemiparesis (weakness in one arm), which is commonly seen after stroke. The objective of this research is to see if a robotic system worn on the weakened arm like a brace is more useful in improving the strength and coordination of the affected arm, and those of other stroke survivors, than therapy only. Muscle weakness and lack of coordination after a stroke have great effects on how severely disabled the arm is and on quality of life after a stroke. In this study, patients may be administered a new robotic brace as part of treatment for their affected arms. If they use this brace, your electromyography (EMG) signals will be used to control the powered arm brace. EMG signals are the small electrical signals that result from the actions of the muscles. The system will "listen" to patients' muscles, using small sensors that sit on top of the skin. The device will give the arm a "power-assist" when patients bend or straighten their elbows. The investigators want to test how easy and effective this system is to use. The investigators hypothesize that people using the robot will be more successful in their rehabilitative efforts - and that their movement will improve more - than people receiving traditional therapy.
The purpose of this study is to determine whether levels of circulating endothelial progenitor cells (cEPC) are increased in the acute phase of ischemic stroke.
Stem cell theray in old stroke patients is a study to treat stroke patients approved before in our hospital. We recruit these patients who received stem cell therapy and completed the study. We adopted movement-related cortical potential,and cortico-cortical inhibition to assess the stroke patients with or without stem cell therapy. Further analyzing the correlation of the motor related cortical potential and cortico-cortical inhibition among them. We wanted to find out if there are changes in cortical excitability in subjects with chronic stroke after stem cell therapy.
The purpose of this study is to evaluate whether the serum apoB48 level is associated with atherosclerotic ischemic stroke.
The trial was designed to test the hypothesis that early treatment with nimodipine has a positive effect on cognition impairment after acute ischemic stroke.
Whole body vibration has been found to be useful in promoting bone health, balance, and muscle performance in older adults. The overall aim of the proposed study is to determine whether whole body vibration (WBV) has immediate beneficial effect in neuromotor performance in patients with stroke. It is hypothesized that a single session of WBV will induce significant improvement in leg muscle strength in people with chronic stroke.
Recent work showed that application of peripheral nerve and cortical stimulation independently can induce 10-15 % improvement in motor performance in patients with chronic stroke. The purpose of this study was to compare in post-stroke hemiplegic patients the effect on motor recovery of one session of anodal transcranial direct current stimulation to the ipsilesional primary motor cortex (M1) combined with a peripheral radial nerve electrical stimulation (rEPNS) to the paretic hand repeated 5 successive days with the effect of the same peripheral nerve stimulation combined with sham tDCS. Design: randomized, double-blind, parallel controlled clinical trial. Patients eligible for the study: Acute ischaemic stroke Primary outcome measure: Jebsen Taylor test Secondary outcome measures Nine peg hole test Hand tapping grip and wrist force Cortical excitability of Ipsilesional M1(TMS) Follow-up: 30 days
1. Objectives and Hypothesis 1. Objectives: This study evaluates whether strict BP management is useful for the prevention of recurrent stroke. Hypertensive patients with history of stroke are treated with stepwise multi-drug therapy to achieve stricter BP target <120/80 mmHg in the strict BP control group and less stricter BP target <140/90 mmHg or <130/80 mmHg for patients with current DM/CKD/MI in the standard BP control group. The participants under the BP treatment achieving their respective BP target will be followed for recurrence of stroke. The study continues until the number of patients with the first recurrent stroke reaches a total of 330 between the two groups. The occurrence rates of recurrent stroke will be compared between the two groups. 2. Hypotheses The incidence of recurrent stroke will be lower in a strict BP control group having lower BP target: <120/80 mmHg* than in a standard BP control group having BP target <140/90 mmHg or <130/80 mmHg for current DM/CKD/MI in patients with hypertension. 2. Study design This will be a multicenter, randomized, open-label study. The study consists of a screening period, a titration period and a follow-up period. The screening period is a period between the date of consent and the enrollment date. Hypertensive patients with history of stroke are randomly assigned to either the strict BP control group having the target of <120/80 mmHg or the standard BP control group having the target of <140/90 mmHg without current DM, CKD or MI and <130/80 mmHg with current DM, CKD or MI. The titration period is the period finding a treatment which achieves target BP, and 24 weeks at maximum. Patients will be treated with stepwise multi-drug therapy using an angiotensin-receptor antagonist, diuretic, calcium channel blocker and aldosterone antagonist. The participants will be observed under the BP management for their respective BP target. The study will be continued until the number of patients with the first recurrent stroke reaches a total of 330 between two groups. The follow-up period will be 3 years. The recurrent rates of stroke in both groups will be compared from various aspects, and strict BP management will be investigated on the usefulness in prevention of recurrent stroke.
