Filter by:CAIS-MT is a single-center, prospective cohort study, to evaluate the correlation between outcomes of endovascular treatment(EVT) and intracranial artery calcification(IAC) in patients with acute ischemic stroke due to large or medium vessel occlusion.
The goal of this clinical trial is to learn if transcranial magnetic stimulation(rTMS) can improve neurological rehabilitation in patients with acute ischemic stroke. The main questions it aims to answer are: Can rTMS Promote Recovery of Limb Impairment in Patients with Acute Ischemia? Can rTMS Cause Changes in the Functional Connections of Brain Networks in Patients? Researchers will compare rTMS therapy to non-stimulation therapy to see if rTMS is effective in promoting neurological recovery from ischemic stroke. Participants will: Receive rTMS or sham stimulation with LF-rTMS on the contralateral M1 of the brain lesion for 20 minutes, 1200 pulses, 120% RMT, and a treatment period of 5 days； Be evaluated on a scale before and after treatment
The aim of this study was to investigate the effect of dual-task training on gait, balance, and quality of life in individuals with stroke. The study included 30 individuals aged 30-80 years with stroke. All participants were assessed using the 10-meter walk test (10MWT), 10MWT under dual-task interaction (DTI), timed up and go (TUG), 30-Second Chair-Stand Test (30s-CST), Berg Balance Scale (BBS), Short Form 36 (SF-36). Participants were randomized into two groups. Both groups received conventional physiotherapy for approximately 1 hour, five days a week. Group I also received dual-task training.
Upper limb deficits usually remain in 75% of the stroke survivors despite completing full rehabilitation. This is due to lack of effectiveness of rehabilitation and the degree of support and resources available. In this study, the investigators plan to study the use of assistive technologies in chronic stroke survivors.
The goal of this observational study is to understand the impact of spasticity on muscle changes and functional performance in stroke patients with lower limb spasticity in comparison to non-stroke individuals. The main questions it aims to answer are: - How does spasticity affect muscle changes and lower limb functional performance in stroke patients? - How do structural and textural parameters in ultrasound images differ between spastic stroke patients and non-stroke individuals? Participants will undergo ultrasound evaluation of their leg muscles to measure structural and textural parameters. They will also take part in functional assessments to assess their performance in activities related to lower limb mobility. Researchers will compare the structural and textural ultrasound parameters between stroke patients and non-stroke individuals to determine any notable differences. The study aims to identify the relationship between muscle changes, spasticity, and functional performance in stroke patients.
The purpose of this study is to capture sensorimotor ankle function in a chronic stroke population through validation of novel, experimental metrics and their comparison with established, clinical measures of function. For this purpose, the researchers will evaluate various single-joint, impairment-level measures such as visuomotor tracking performance and proprioception as well as functional-level measures including spatiotemporal gait (e.g., gait speed and stride length/time) and standardized clinical scales. This study will be carried out in chronic stroke patients as well as age-matched healthy controls. Results will help the researchers identify more quantitative metrics that can be used to monitor and rehabilitate sensorimotor function following stroke.
The objective of this research is to evaluate the benefits of an experimental therapy for motor recovery of the arm after a stroke, which includes the application of a functional electrical stimulation therapy coupled to P-300 based Brain-Computer Interface system (BCI-FES). For this purpose, the investigators will compare two groups, the first one will receive only conventional physical and occupational therapy, while the second one will receive conventional therapy together with BCI-FES therapy. The control and experimental group will receive 20 sessions of conventional physical and occupational therapy at a rate of five sessions per week for 4 weeks (control group double dose of conventional therapy), and the experimental group will receive 20 sessions of rehabilitation with the BCI-FES system at a rate of five sessions per week for 4 weeks. Broadly speaking, the BCI is in charge of determining the movement selected by the individual and assist the hand movement while performing functional tasks. The movements included in the sessions will be hand opening, grasping, pinching, pronation and supination, which are combined to facilitate the execution of functional movements that are performed together with the manipulation of daily used utensils. The visual, sensory and motor feedback provided by the BCI-FES system that enables the individual to replicate the afferent-efferent motor circuit, contributes to the activation and recruitment of neural pathways, which is associated with motor recovery. It should be noted that this BCI-FES system has already been tested previously in a study with healthy individuals, and in a non-randomized pilot study that used this therapy for upper limb motor function recovery in chronic post-stroke patients. To evaluate the results, a series of tests will be applied to assess the motor recovery, including the FMA-UE: Fugl-Meyer Assessment Scale of Upper Extremity, ARAT: Action Research Arm Test, MAS: Modified Ashworth Scale, FIM: Functional Independence Measure and MAL: Motor Activity Log. Likewise, resting state functional magnetic resonance imaging studies will be performed to evaluate the degree of functional connectivity between various brain regions of interest related to the planning and execution of movements. This will determine whether the experimental therapy with BCI-FES favors arm and hand recovery in surviving stroke individuals.
Strokes are estimated to be the third most common cause of death in the world and the second most common cause of disability. Recently, the incidence of stroke has increased due to population aging. It is common for stroke survivors to experience a functional decline in their capacity to carry out daily activities as a consequence of their increasing dependence, which ultimately affects motivation levels, self-efficacy, and quality of life. Following a stroke, people often experience problems with upper limb function. Over half of people with upper limb impairments who have suffered a stroke continue to experience problems months or years afterward. A significant amount of rehabilitation is necessary to obtain meaningful recovery in the upper extremities and balance, but such interventions are difficult to access. As a cutting-edge method of neurorehabilitation, extended reality technology like virtual reality provides a more intensive simulation of functional activities than traditional physical therapy methods (aerobic, resistance, flexibility exercises, balance and coordination training, and functional exercises. The non-immersive type of VR can provide the patient with a safe experience so they can practice their exercises using gamification features integrated into the VR system, while remaining aware of their surroundings. According to the most recently published studies, there is promising evidence regarding the use of home-based exercises in stroke management especially after the Covid-19 pandemic. However, there is still a gap in identifying the evidence for using non-immersive home-based virtual reality exercises as telerehabilitation on the upper limb function and balance motor outcomes, adherence, and compliance with rehabilitation programs. In addition, no study have evaluated the validity and fidelity of the gamified features that can be added to the non-immersive VR exercises in terms of improving patient adherence and experience to their rehabilitation program. Moreover, the investigators still need rigorous qualitative studies to explore patient experiences after doing these exercises at home with remote monitoring from their rehabilitation team.
The goal of this study is to learn if a behavioral change intervention can improve physical activity in stroke survivors living in the community. The main question it aims to answer is, if a behaviour change intervention and personalised physical activity prescription, are effective in improving the time spent in moderate to vigorous physical activity amongst chronic stroke survivors. Researchers will compare the intervention group to a control group, to see if physical activity counselling and a personalized physical activity prescription is more effective in improving moderate to vigorous physical activity, than usual care alone. The study period for each participant is 6 months. Assessments are conducted at month 1 (baseline), 3 and 6. The control group will receive only usual care, which consists of an information sheet on physical activity with the following content: (1) Why be active and (2) How to be active (with URL links to resources and videos). The usual care is delivered at 3-time points during month 1, 3 and 6. The intervention group will receive usual care and a behavioral change intervention. The behavioral change intervention consists of up to 6 individual physical activity counselling sessions and a personalized physical activity prescription. The 6 sessions will take place only during months 1 to 3 and there will be no intervention during months 4 to 6. Of the 6 sessions, 3 are conducted face-to-face and another 3 sessions will take place using telehealth methods such as phone, text messaging and videoconference. Participants can meet the study physiotherapist at their preferred exercise space during the 3 face-to-face sessions. The physical activity counselling sessions consist of goal setting and action planning, and problem-solving barriers around participation in physical activity. The overall aim is to increase time spent in moderate-vigorous physical activity.
Upper limb hemiparesis is the most common sequelae in patients, severely impacting their independence and quality of life. Transcranial electrical stimulation (tCES) is a non-invasive and safe treatment, which uses a low direct current or alternating current to change the excitability of the cerebral cortex. It can induces long-term potentiation-like or long-term depression-like effects, thereby modulating the cortical excitability. In recent years, researchers have developed high-definition (HD) devices, which integrate high definition ring electrode configurations and incorporate direct current with theta burst stimulation waveforms. Diverging from traditional transcranial direct current stimulation (tDCS), which applies weak currents (0.5-2 mA) through two large sponge electrodes (25~35 cm^2) externally to the scalp for widespread non-specific cortical stimulation, HD-tES employs an array of small-area electrodes (1 cm^2) to control current distribution over localized cortical regions, thereby enhancing spatial accuracy. However, there is a lack of studies validating the optimal waveform for HD-tES, as well as clinical evidence in subacute stroke populations. The optimal unilateral versus bilateral stimulation modes and their neurological mechanisms for stroke rehabilitation also remain uncertain.
