Active clinical trials for "Stroke"

This clinical trial was planned for the purpose to re-evaluate the safety and efficacy of naloxone hydrochloride in ischemic cerebral nerve disorders caused by stroke and cerebral hemorrhage. Eligible subjects will be randomized to the naloxone hydrochloride group or placebo group at 1:1 ratio. Also, factors, such as disease subtype and severity, which might impact the efficacy endpoints will be used to stratify. - Stratification factor: cerebral infarction (NIHSS 5-15 points or 16-20 points) or cerebral hemorrhage Administration of investigational product should be started within 48 hours from the onset of symptoms. Subject receive the investigational product 7 consecutive times (for 7 days) in a single dose of intravenous infusion for 24 hours.

Stoke is a leading cause of disability that results not only in persistent neurological deficits but also profound physical de-conditioning that propagates stroke-related secondary disability. Several kinds of research have reported that there has been asymmetrical weight bearing on the affected side while sitting and standing resulting in impaired performance especially reaching in sitting, rising from the chair, walking, and climbing stairs. Despite the stroke patient being able to walk independently with or without the walking aids, the patient still lacks the normal movement pattern especially weight transfers on the affected side while performing such activities which subsequently decreases the patient to restrain the challenges while walking, decrease confidence in functional activities. Also, further, there hasn't been enough literature on this topic. Therefore, the objective of this study is to find out the effectiveness of multidirectional stepping and weight shifting exercises to improve dynamic balance and gait speed in stroke patients.

Little is known about mirror therapy and cognitive exercises applied together in patients with stroke by means of telerehabilitation. The aim of this study is to investigate the effects of home-based mirror therapy combined with cognitive exercises on upper extremity functions and cognition in adults with stroke and to compare these effects with mirror therapy alone.

Spasticity after stroke is common that affect upper limb strength and make activities of daily living difficult. There are many techniques but not any standardized technique for long term effect on reduction of spasticity and improving upper limb strength. This study aimed to explore and understand the effectiveness of neural mobilization on reduction of spasticity and improving upper limb strength in individuals with stroke. This is mixed method approach of embedded design, multicentric study recruited 7 individuals with stroke as no new themes or codes were emerging (data saturated). Median nerve mobilization was given 20 oscillations per minute for 3 times & repeated 3 times with a pause of 1 minute between each sets for 5times/week for 4weeks. Outcome measures were Modified Ashworth Scale (MAS), Brunnstrom's grading of hand recovery and Hydraulic hand dynamometer(HHD) for grip and pinch strength. Pre and post outcomes data were collected at baseline and 4weeks after intervention and in depth face to face structured interviews was conducted after 4weeks of intervention to explore the effectiveness of median nerve mobilization on reduction of spasticity and the improvement of upper limb strength.

The aim of this study is to observe and to compare effects of segmental vibration on flexors versus extensor muscle groups on upper limb function in post-stroke patients. This study will be helpful in finding out that either low frequency segmental vibration on flexors muscle group is better in improving upper limb function or low frequency segmental vibration on extensor muscle group is more beneficent in improving upper limb function.

The purpose of this study was to improve the effect of Transcranial Direct Current Stimulation (tDCS) applied during exercise training in stroke patients with upper limb and hand motor function.

Sensory dysfunction following stroke is a common condition. The deficiency in the somatosensory system negatively affects the learning of new motor skills by preventing feedback from the sensory system, and it can also cause problems in daily life, personal care, productivity, and leisure activities. Somatosensory impairment is often overlooked, as rehabilitation often focuses on motor abilities in the affected extremity. In the studies reviewed, it is stated that sensory dysfunction is seen in approximately 50% of stroke patients. The aim of this study is to examine the effects of intensified sensory-based therapy applied to the affected upper extremity sensory functions in individuals with chronic stroke on the upper extremity functions, quality of life, and independence of daily living activities.

Background: Transcranial direct current stimulation (tDCS) has been gaining increasing interest as a potential therapeutic tool to improve upper extremity (UE) rehabilitation outcomes following stroke. Within the concept of interhemispheric inhibition (IHI), most tDCS studies have applied anodal ipsilesional and/or cathodal contralesional primary motor cortex (M1) tDCS to rebalance IHI and enhance motor recovery. However, compelling evidence suggests that an excitation/inhibition model is oversimplified, and the role of both hemispheres in the encoding of information during motor learning should be acknowledged. Moreover, multiple lines of evidence have demonstrated the potential relevance of contralesional premotor cortex (PMC) for recovery after M1 injury. Objective: We are aiming to investigate and compare the effects of two tDCS montages at different cortical sites (Dual-M1 vs. a-tDCS over contralesional PMC) by measuring the clinical outcomes of the most affected UE in patients with chronic subcortical stroke. Methods: 35 participants will be randomly assigned to 1 of 3 groups (Group A received dual- M1 tDCS, Group B received a-tDCS over contralesional PMC, and Group C received sham stimulation). tDCS will be applied using intensity of 2 mA for 20 min. (5 times/week) for 2 consecutive weeks. Fugl-Meyer Assessment of the Upper Extremity (FMA-UE) and Action Research Arm Test (ARAT) will be used to quantify the UE functional motor ability. Box and Block Test (BBT) will be used for gross manual dexterity and Nine Hole Peg Test (NHPT) will be used to measure fine hand dexterity. All measurements will be taken pre-treatment (T0) and post-treatment (T1) immediately after the 10th session, then 4 weeks after the end of stimulation period (T2) to assess the long-term effects. Expected results: This study would verify whether enhancing the motor cortical hyperexcitability in the contralesional hemisphere has a beneficial on recovery of the paretic hand, or regaining the balance of transcallosal inhibitory circuits between the motor areas in both hemispheres has more positive effects on the motor outcomes . This study would also provide a predictive approach to enable realistic rehabilitation goal-setting by identifying the proper tDCS montage for patients with stroke depending on their impairment level.

The overall goal of this project is to determine if machine learning and analysis of neurospecific biomarkers can enable early detection of upcoming or ongoing cerebral ischaemia in patients suffering from subarachnoid haemorrhage with altered consciousness due to cerebral injury or sedation. Analyses of heart rate variability, electroencephalgraphy,nearinfrared spectroscopy, cerebral autoregulation, and brain injury specific biomarkers in blood and cerebrospinal fluid will be performed.

The purpose of this research is to better understand the impact of cortically-induced blindness (CB) and the compensatory strategies subjects with this condition may develop on naturalistic behaviors, specifically, driving. Using a novel Virtual Reality (VR) program, the researchers will gather data on steering behavior in a variety of simulated naturalistic environments. Through the combined use of computer vision, deep learning, and gaze-contingent manipulations of the visual field, this work will test the central hypothesis that changes to visually guided steering behaviors in CB are a consequence of changes to the visual sampling and processing of task-related motion information (i.e., optic flow).
