Filter by:Background: Stroke is the leading cause of disability in the western world. In chronic stroke patients, foot deformity such as pes equinovarus is among the most important underlying motor deficits, due to imbalance of muscle strength and activity around the ankle and tarsal joints. Both nationally and internationally, there is relative underuse of surgical treatment options, although in our clinical experience this often has the best outcome. In addition to positive clinical experiences with surgical interventions, we have experienced that before surgery, there is limited effect of gait training on gait capacity. However, we have experienced that after surgery, the restored normal ankle-foot position creates a new window for training opportunities to further improve gait capacity. Therefore, in this exploratory proof of principle study we aim to investigate the effect of surgical correction of post-stroke foot deformity on the (potential) improvement of gait capacity after gait training. Based on clinical experiences, we expect that after surgery, gait training results in a larger improvement in gait capacity compared to before the surgical intervention due to the increased possibilities to improve balance control. Objective: The primary objective of this study is to compare the effect of gait training on gait capacity (stepping performance, gait adaptability and dynamic balance) before and after surgical correction of post-stroke foot deformity. Study design: Exploratory proof of principle study with repeated-measures. Study population: Fifteen stroke patients with disabling foot deformity will be recruited from the Gait Expertise Center (LEC) of the Sint Maartenskliniek and Radboudumc. Intervention: All patients will receive two gait training interventions, each consisting of twelve one hour training sessions. The training sessions will be focussed on improving gait capacity. Main study parameters/endpoints: Primary outcomes will be gait adaptability as measured with the Emory Function Ambulation Profile (E-FAP), stepping performance as measured with the Timed-Up-And-Go test (TUG) and dynamic balance as measured with the Margin of Stability (MoS).
This study aims to develop a neurophysiological marker for post-stroke participants that predicts upper extremity motor recovery in response to a standard upper extremity rehabilitation protocol of task-specific training (TST). For this aim, the researchers will utilize transcranial magnetic stimulation (TMS) combined with electromyography (EMG) and electroencephalography (EEG) to observe inpatients with stroke-related hemiplegia and follow their recovery through outpatient for up to 3 months. Motor-evoked potentials (MEPs), transcranial-evoked potentials (TEPs), action research arm test (ARAT) scores, and clinical outcome measures will be recorded at different time points of the inpatient rehabilitation period. The researchers hypothesize that changes in motor recovery will be reflected in changes in the MEPs and TEPs.
Altered brain networks, including cognitive, motor, and language networks, are investigated by intensive cognitive rehabilitation in subacute stroke patients.
By inducing endogenous neuroprotection, hypoxic post-conditioning following stroke may represent a harmless and efficient non-pharmacological innovative neuro-therapeutic modality aiming at inducing neuroplasticity and brain repair, as supported by many preclinical studies. The investigators thus hypothesize that hypoxic post-conditioning represents a safe therapeutic strategy post-stroke. The investigators further hypothesize that hypoxic conditioning could enhance neuroplasticity and function in combination with conventional rehabilitative care. The primary study endpoint will be safety. Safety will be assessed through the clinical review of the adverse events over the duration of the study, every 48 hours by a trained evaluator, blinded for the therapeutic intervention. The investigators will further investigate the potential functional benefits of such a therapeutic approach on motor function, gait, balance, and cognition. The neurophysiological substrates of hypoxic conditioning-triggered neuroplasticity at a subacute delay post-stroke will also be investigated, based on biological and imagery markers.
This multi-center, randomized, parallel-group, double-blind, placebo-controlled study will evaluate the efficacy and safety of TB006 in participants with an Acute Ischemic Stroke (AIS) event with 57 days of treatment.
The pilot randomized controlled trial aims to assess effects of a guided online acceptance and commitment therapy (ACT) intervention on distressed stroke survivors compared to the care-as-usual control group. A total of 24 stroke survivors who meet the inclusion criteria will be recruited and randomized to either the intervention group or the control group. Exploratory hypotheses are that the ACT group will show improvements in mental health outcomes (e.g., depressive symptoms, anxiety, and stress), and ACT processes (e.g., psychological flexibility/acceptance) at posttest and 2-month follow-up, compared to the care-as-usual control group. Also, the project will evaluate the feasibility of recruitment, adherence, and retention of participants and explore participants' experiences in the ACT intervention through semi-structured interviews at posttest.
In this pilot trial, the investigator will compare early post-stroke BP management using an integrated Telehealth After Stroke Care (iTASC), to usual care with a primary outcome of BP control defined by the mean 24-hr blood pressure through remote monitoring at 3 months and survey patient reported outcomes. As this is a preliminary trial with a small sample, estimates derived will be used to plan the subsequent larger confirmatory trial. Descriptive statistics will characterize the randomized patients completing surveys and outcome assessments. The study will evaluate the primary clinical outcome (BP <140/90 mmHg) 90 days post-discharge as a function of treatment and adjusted for from baseline BP. Change from baseline BP will also be assessed as an outcome. Change in activity level and duration, as well as trends in sedentary time will be compared between arms, and pre- and post-intervention with visual tailored infographics in the intervention arm. Moderating effects of demographics will also be evaluated. Decisions regarding the pursuit of a subsequent trial will use the primary outcome, and analysis of all other measures will be hypothesis generating.
The Synchron Motor Neuroprosthesis (MNP) is intended to be used in subjects with severe motor impairment, unresponsive to medical or rehabilitative therapy and a persistent functioning motor cortex. The purpose of this research is to evaluate safety and feasibility. The MNP is a type of implantable brain computer interface which bypasses dysfunctional motor neurons. The device is designed to restore the transmission of neural signal from the cerebral cortex utilized for neuromuscular control of digital devices, resulting in a successful execution of non-mechanical digital commands.
The objectives of this pilot project are to determine whether pairing rTMS with an evidence-based PST intervention is acceptable to and feasible for individuals with executive function deficits after stroke and whether rTMS enhances executive functioning and uptake of the PST intervention to improve generalization of the PST strategy and support long-term goal attainment. To achieve the objectives, the investigators propose two specific aims: AIM 1: Establish the acceptability and feasibility of delivering up to 6 sessions of PST+ rTMS to individuals with executive function deficits ≥ 6 months post stroke. Hypothesis 1a:80% participants will complete 6 PST sessions. Hypothesis 1b: 1b: Participants who receive rTMS directly prior to the PST intervention will report higher satisfaction with the overall intervention compared to those who receive rTMS simultaneously with PST. AIM 2: Assess the initial efficacy of PST+rTMS for improving patient outcomes in individuals with stroke. Hypothesis 2a Patients will demonstrate a significant increase in executive functioning (ie. attention, immediate memory and cognitive flexibility and reasoning) as measured by the Digit Span Test and Wisconsin Card Sorting Test. Hypothesis 2b: Patients will achieve 80% of self-set goals. Hypothesis 2c: Patients will demonstrate a significant increase in task-oriented coping skills as measured by the Brief Cope at 1-month post intervention.
