Filter by:The specific study aims will be: 1. To examine the treatment effects of a new digital mirror therapy (MT) system versus a mirror box in patients with stroke by conducting a 4-group randomized controlled trial. 2. To examine the electrophysiological mechanisms of uni-mirror visual feedback (uni-MVF) condition with unimanual training mode, uni-MVF condition with bimanual training mode, and bi-MVF condition with bimanual training mode in the new MT system by EEG.
The proposed study evaluates the effect of ankle foot orthosis (AFO) heel height and stiffness on the forces and motion of the lower limb during over-ground walking in individuals who use an AFO for daily walking. Previous studies suggest that heel height and stiffness effect limb loading, but these data and the analysis techniques applied are limited. In this study, heel cushions with different height and stiffness's (4 conditions) will be placed in participants shoes and they will walk at controlled and self-selected speeds. Participants will also walk with their AFO as configured prior to enrollment, and with no AFO if possible. The proposed study will provide evidence that can be used by clinicians and researchers to align braces that most effectively improve function during every-day walking.
The purpose of this study is to investigate if a person with weakness or paralysis in one or both arms, can use the NuroSleeve combined powered arm brace (orthosis) and muscle stimulation system to help restore movement in one arm sufficient to perform daily activities. This study could lead to the development of a product that could allow people with arm weakness or arm paralysis to use the NuroSleeve and similar devices to improve arm health and independent function.
This study will compare the VerTouch device to the conventional palpation technique for performing diagnostic and therapeutic neuraxial procedures.
Multiple sclerosis (MS) is a chronic, inflammatory disease of the central nervous system. Lack of physical activity is common in people with MS (pwMS). This can lead to several comorbid conditions such as obesity, metabolic syndrome, osteoporosis, hypertension, diabetes and worse prognosis. An increasing number of studies suggest that physical exercise can play an important role in managing symptoms, preventing complications and comorbidities in pwMS, and may possibly be neuroprotective. However, doing exercise can be very challenging for pwMS who have moderate/severe mobility disability and who have problems with walking. In this project, the investigators will explore the use of a powered Exoskeleton as an exercise tool for people with moderate to severe difficulty walking due to MS. Powered Exoskeletons are wearable robots that offer opportunity to persons with lower limb weakness to stand and walk. The Exoskeleton-assisted training provides active training with potentially much less intervention needed from therapists. However, it is not clear whether pwMS can walk with a powered Exoskeleton at speeds and intensities sufficient to positively affect health and fitness outcomes. Thus, in this study, the investigators aim to explore whether using an Exoskeleton will enable people with MS to exercise at a moderate intensity and whether people with MS find this acceptable and safe to do on a regular basis. The investigators will also explore whether training with an Exoskeleton can improve walking. The investigators will train 12 patients with MS to walk with an Exoskeleton twice a week for 8 weeks. The investigators will compare the effects with another group of 12 patients who will do exercises with a fitness instructor twice a week for 8 weeks. The investigators will study whether walking with Exoskeleton is better than fitness training in terms of fitness outcomes, walking and cognitive, psychological factors.
Dopaminergic drugs partially alleviate gait problems in Parkinson's disease, but the effects are not sustained in the long-term. Particularly, the freezing of gait, balance problems and other gait issues directly impacts patients' quality of life. Experimental epidural spinal cord stimulation studies have suggested positive effects on locomotion among PD patients, but the effects of non invasive stimulation have never been explored.
The study seeks to investigate whether 24 weeks of power training has neuroprotective effects in older PwMS. Additional purposes are to examine the effects of 24 weeks power training on physical function, cognitive function and neuromuscular function. Further, it is investigated whether the potential effects of power training are maintained after 24 weeks of follow-up.
The objective of this study is to develop and evaluate novel robotic training strategies that modulate errors based on the subjects' individual motor and cognitive needs. For this purpose, healthy adults and neurologic patients will participate in robotic motor learning experiments. Patients have a diagnosis of a neurological disease (i.e., stroke, spinal cord injury, multiple sclerosis, Guillain-Barré syndrome) limiting arm motor function.
The study design is a single-center prospective pilot study. Hypothesis: Results of cerebral fNIRS examination in unconscious patients with severe hemorrhagic or ischemic stroke in the ICU are congruent with the results of SSEP and AEP. Hence, making it a potential prognostic tool for unconscious ICU patients. In a specific subgroup of unconscious patients after cardiac arrest and cardiopulmonary resuscitation the fNIRS measurement is congruent with the results of electroencephalography (EEG). The primary purpose of this study is to evaluate the agreement of the results of fNIRS examination to those of evoked potentials and EEG in unconscious ICU patients with severe hemorrhagic, or ischemic strokes or hypoxic brain injury after cardiac arrest and cardiopulmonary resuscitation. fNIRS will be compared to evoked potentials in an experimental group consisting of unconscious neuro-intensive care patients and in a control group consisting of healthy, conscious subjects. To compare fNIRS with evoked potentials there are two test phases: 1. The cerebral response to a somatosensory stimulus (peripheral nerve stimulation) is measured by fNIRS and SSEP 2. The cerebral response to an auditory stimulus is measured by fNIRS and AEP To avoid biases the following has to be considered: - The timing of the measurements plays an important role. A time difference between compared measurements can influence the outcome significantly due to deterioration or recovery of the neuronal network during the time gap. Therefore, fNIRS and evoked potentials will be measured simultaneously. - If the compared measurement methods are conducted by the same researcher the possibility of bias is high. Hence, two different researcher will conduct each one measurement without knowing the results of each other during the measurement.
Background: Stroke is a leading cause of long-term disability in the US. Mild stroke comprises half of stroke hospital admissions, but most people with mild stroke receive no rehabilitation services. Mild stroke is often the manifestation of uncontrolled chronic conditions (e.g. hypertension, diabetes), and people with mild stroke also experience ongoing chronic symptoms (e.g. depression, fatigue) that may impact their daily activities. An inability to manage chronic conditions and symptoms may lead to decreased participation in pre-stroke roles and activities, which may increase the chance of sustaining a second stroke. An effective intervention to manage chronic conditions and support participation is self-management. A meta-review of 13 systematic reviews demonstrated that self-management interventions significantly improve stroke survivors' daily activities, independence, and mortality. National research agendas from the Department of Health and Human Services (HHS) and Institute of Medicine (IOM) include self-management as one key goal of a strategic framework, aligning with the AOTF Research Priorities, for promoting (1) health behaviors to prevent and manage chronic conditions. Our preliminary studies indicate that mobile health (mHealth), defined as the delivery of healthcare services via mobile devices, can be used to precisely monitor participation in daily activities and mood and is acceptable in stroke survivors. Our meta-analysis indicates that digital self-management interventions are more effective in improving depression, fatigue, anxiety, and self-efficacy in people with neurologic disorders in comparison to non-digital self-management interventions. These studies support the AOTF Research Priorities that include (2) use of technology to support home and community activities, and (3) emotional influences. Objectives: The investigators will harness mHealth technology for a self-management program. Our intervention is a mobile phone intervention called iOTA, which builds on extensive work by my mHealth mentor and colleagues in health behavior research. The investigators will use a formal implementation science framework to adapt and test the iOTA intervention. The investigators will cohere an adaptation framework by soliciting stakeholder input to adapt the iOTA from Improving Participation after Stroke Self-Management (IPASS), an evidence-based intervention that targets self-management of chronic conditions and increased community participation in stroke survivors. Methods: The investigators will use a two-step approach, including a rigorous treatment adaptation and a Phase I feasibility trial. Our first step is to adapt the intervention with input from all relevant stakeholder levels. Our second step is to use a pre-post, non-randomized study design to test the adapted iOTA. Ten community-dwelling people with mild stroke will participate in the iOTA for 3 months. The iOTA incorporates daily short message service (SMS) text messages to supplement monthly in-person health coaching and weekly videoconference sessions. The investigators will include an occupational therapist (OT) as a health coach to teach individuals to incorporate self-management strategies into their daily routines to support participation in meaningful activities. Expected Outcome: This mHealth treatment development study will increase the reach and access of IPASS-a patient-centered, participation-focused self-management program for stroke survivors. The iOTA created will not only maximize our potential for the future randomized controlled trial (RCT) but also lay the groundwork for future funding mechanisms.
