Filter by:The purpose of this study is to provide further information regarding the risks and benefits of Dysport in marketed indications.
The purpose of this study is to see if providing training using a Sit-to-Stand protocol for residents of Long-Term Care Facilities who have had a stroke will increase their independence in performing Sit-to-Stand.
The purpose of this study is to explore the severity of malnutrition and inflammation in Taiwanese hemodialysis patients.
The aim of this study is to investigate whether additional task specific physiotherapy treatment and a self administrated home training program results in better balance compared to traditional follow up care.
This is an interdisciplinary, intervention study with stroke survivors and their spousal caregivers after discharge from a rehabilitation unit. It will determine whether couples receiving home visits from nurses and therapists over a 6 month period demonstrate better function and less psychological distress than couples who receive information by mail. All couples are visited every 3 months by a nurse who assesses their physical and psychosocial functioning.
This study will determine the effectiveness of sertraline administration after a stroke in preventing the onset of post-stroke depression.
The Northern Taiwan Stroke Center for Prevention and Treatment Project is a single medical center, 3-year, multipurpose study. The aims of this study are (1) to set up a multidisciplinary stroke team in a well-designed stroke center for stroke care; (2) to establish a systemic stroke prevention / education protocol based on people's awareness of stroke; and (3) to create a better stroke rehabilitation protocol and pathway.there are three components in rehabilitation projects. First, we want to identify potential factors related to functional outcome in patients with stroke before and after stroke center. Second, we want to compare the functional outcome in patients who admit to the stroke center as to those admitted to the general ward. Third, we want to investigate the effect of electrical stimulation on upper limb function in patient with acute stroke.
According to the theory of wave transmission, the speed of wave transmission is dependent on the nature of the transmission medium, which is the vessel wall for pulse wave transmission. Then, the pulse wave velocity is related to the mechanical property of the vessel wall. The mechanical property of the vessel wall is determined by the texture of the vessel wall and the contraction status of the smooth muscle within the vessel wall. Because the texture of the vessel wall could not be changed in a short duration, the sympathetic nerve activity, which controls the contractibility of the smooth muscle, becomes the only determinant factor of pulse wave velocity. So, pulse wave velocity may reflect the status of sympathetic nerve activity. The purpose of this project is to use the pulse wave velocity to measure the sympathetic activity of stroke and spinal cord patients. The present project plans to measure the pulse wave simultaneously at four limbs by pressure receptors, and use the electrocardiogram as the reference to synchronize the recorded pulse wave at different vessels, using the corrected data to calculate the pulse wave velocity. With the pulse wave velocity of different vessels, we, the investigators at National Taiwan University Hospital, can understand the local sympathetic nerve activity in different diseases and different sites. The first year, we will set up the equipment for measuring the pulse wave velocity, and then apply it to 20 healthy subjects to adjust the measurement error and ascertain the reproducibility of the machine. The second year, we will apply the measurement to 15 complete cervical cord injury individuals and 15 healthy subjects in different erected angles by a tilting table. This procedure will make us understand the response of sympathetic nerve activity to different postures in normal subjects and cervical cord injury patients. The third year, we will apply the measurement to 30 cerebrovascular accident patients to understand the change of sympathetic nerve activity after having a stroke. By comparing the clinical information, we hope to clear up the relationship between sympathetic nerve activity and pulse wave velocity.
Ultrasonographic examination has long been used to assess the swallowing function. It has the advantages of no ionizing radiation on examination and the possibility of using the real food instead of the barium meal in testing. Thus, the subjects can be examined repeatedly and in a more physiological status of swallowing. However, the ultrasonographic examination is only used in assessing the oral phase of swallowing. It can accurately visualize the tongue movement, measure the oral transit time of bolus, and sometimes the hypoid bone motion, but has not been applied on the evaluation of pharyngeal phase of swallowing. Physically, laryngeal elevation is an essential component of the swallowing movement on pharyngeal phase. It ensures the occlusion of airway and opening of criopharymgeus muscle, and thus prevents the aspiration. To evaluate the laryngeal elevation is crucial point in managing the dysphagic patients. The purpose of this project is to measure the laryngeal elevation in normal and in dysphagic patients with cerebrovascular (CVA) accident using ultrasonographic techniques. This work will include four group subjects. The first group consists of 20 young subjects (< 40 years); the second group consists of 20 age-matched normal subjects; the third group consists of 20 CVA patients without swallowing problems, and the fourth group consists of 20 CVA patients with dysphagia, which was proven by VFSS. The laryngeal elevation is detected by ultrasound with the transducer placing between the hyoid bone and thyroid cartilage. The two markers are easily detected on sonogram because of the presence of acoustic shadow, a specific character of bony structure on sonogram. The distance between the hyoid bone and thyroid cartilage before and during swallowing is measures and compared among the groups. The distance change of the patients with dysphagia is further compared with that defined by VFSS. With the result of this study, we will understand the status of laryngeal elevation during swallowing in normal and dysphagic subjects, and further determine the accuracy of ultrasonographic measurement in measuring the laryngeal elevation. With this knowledge, we might extend the usage of ultrasonographic examination on evaluating swallowing function.
The main purpose of this study is to evaluate the efficacy of atorvastatin treatment during 3 months (80mg/day) on cerebral vasoreactivity (CVR) in lacunar patients.
