Active clinical trials for "Stroke"

The objective of this study is to determine if the acute effect of vibration from a smartwatch on hand function is comparable to the effect of an existing laboratory prototype.

The aim of the present study is to evaluate the possible effect of using dual-tDCS applied before conventional physical therapy on motor functions and hemodynamic response

Stroke is the second leading cause of death, accounting for 11.13 % of total deaths, and the main cause of disability worldwide. The major type of stroke is ischemic, which occurs in about 87% of all stroke cases Stroke has different risk factors, which can be grouped into modifiable and non-modifiable risk factors. Major risk factors for stroke include age, history of cerebrovascular event, smoking, alcohol consumption, physical inactivity, hypertension, diabetes mellitus, cardiovascular diseases, obesity, metabolic syndrome, diet, nutrition, and genetic risk factors. Many new technique used for rehabilitation after stroke includes Constraint-Induced Movement Therapy for Arm or Leg Paralysis, Mirror Therapy for Hand Recovery, Harness the Relentless Force etc. Segmental muscle vibration (SMV) is also a new technique and effective to decrease the hyper-toned muscles spasticity but still less work done on it. SMV with different frequencies have different effects for both flaccid and spastic patients of all 3 stages of stroke. In our study we will work with 60hz and 120hz frequencies to reduce the spasticity of upper limb and improves their functional level.

Virtual reality training had already been used in stroke rehabilitation, and previous studies supported that it could improve upper extremity ability and increase motivation and pleasure than conventional methods. Pablo is a new VR game combined with motion sensor system which can detect subject's activities. Unlike commercial camera systems such as Kinect or XBOX, the systems require a continuous sightline or enough active range of motion which may increase risk of compensatory movement. Few of studies had investigated the rehabilitation effects on upper extremity with Pablo for patients with stroke.The purpose of this study is to investigate the effects of virtual reality upper extremity training through Pablo system in patients with chronic stroke.

Uncertainty remains regarding the impact of enteric-coated (EC) aspirin as it relates to the reduction of CV risk. We hypothesize that EC formulation based on the previous report may blunt aspirin response as evidenced by reduced Thromboxane A2 (TXA 2) levels in diabetic patients.

The investigators don't fully understand how, regardless of the size or location in the brain, minor strokes can result in significant problems with focus, attention, and multi-tasking that prevent individuals from returning to an active lifestyle, and negatively impact quality of life; but the investigators' preliminary data using magnetoencephalography (MEG) suggest that there may be disruption of the neuronal network and abnormal frontal lobe activity in the brain after stroke. Mindfulness Based Stress Reduction (MBSR) is effective at treating frontal lobe dysfunction in the form of anxiety and depression occurring during the chronic phase of stroke recovery. The aim of this study is to use MBSR to improve other forms of frontal lobe dysfunction (cognitive outcomes) during the subacute phase of recovery, when patients are making critical decisions regarding patients' ability to return to work or live independently; and to use MEG, a tool capable of imaging brain activity and neuronal networks, to understand the brain changes that correspond to improvement after treatment.

The purpose of this project is to establish initial feasibility and tolerability of a combined aerobic exercise (AEx) and upper extremity motor practice intervention on upper extremity (UE) function in chronic stroke survivors. This novel intervention pairs AEx with a virtual reality-based upper extremity rehabilitation game, Duck Duck Punch (DDP). AEx has been shown to improve overall brain function and promote a healthy brain environment; thus it may serve as an effective 'primer' and enhance the effects of DDP. Movement-based priming for rehabilitation involves performing movement or exercise before, or simultaneous to, an intervention with the goal of improving the effectiveness of the intervention. AEx combined with UE rehabilitation can improve UE function and self-reported health status in chronic stroke survivors. However, gaps remain regarding the clinical applicability of an AEx priming session and the mechanisms contributing to changes in UE functions in response to AEx-primed UE rehabilitation. Therefore, the aim of this project is to: 1) demonstrate the feasibility of pairing AEx + DDP in stroke survivors; 2) quantify the magnitude of the effect of the AEx + DDP intervention on UE function; 3) examine relationship of biomarkers of the nervous system and response to AEx + DDP.

This study evaluates the feasibility and effectiveness of an oropharyngeal exercise (O-PE) regimen in treating post-stroke obstructive sleep apnea, as an alternative therapy to continuous positive airway pressure (CPAP). Eligible patients will be randomized (1:1) to treatment using a pre-specified schedule of O-PEs vs. a sham control arm.

This study will examine the feasibility and effect of a program that combines exercise and feedback from a wearable device on upper limb movement practice and function in individuals with stroke.

The aim of this study is to investigate the effects of intermittent theta burst stimulation primed with continous theta burst stimulation (cTBS), on top of a standard robot-assisted training (RAT) on improving the upper limb motor functions of stroke survivors and to explore potential sensorimotor neuroplasticity with electroencephalography (EEG).
