20 Clinical Trials for Various Conditions
The specific aim of this study is to evoke functional movement in the hand of both healthy individuals and individuals diagnosed with a stable cervical spinal cord injury with non-functional movement of the fingers. The primary purpose of this study is to determine the feasibility of achieving refined hand movements through electrical stimulation of the muscles within the forearm. It is believed that this study will be able to identify specific stimulation parameters and electrode spatial configurations responsible for various refined hand movements. After an eligible individual agrees to participate in this study, s/he will receive transcutaneous electrical stimulation on the forearm in order to evoke different hand and finger movements. The precision, specificity, and extent of these movements will be visually assessed. In order to better evaluate these movements, participants may also be asked to perform various functional tasks with their hand. The grip strength and evoked forces at the fingertips will also be measured using sensors. There will be up to 4 study sessions each week for up to 8 weeks, with each session lasting up to 4 hours. Upon completion of these study sessions, the individual's participation in the study is considered complete.
Using a randomized trial design, the goal of this project is to prospectively compare outcomes from a telemedicine-based model of care to two cohorts: patients who receive in-person pediatric physiatrist medical direction (the "gold standard"), and those who receive medical oversight from non-specialist community providers. This project will determine the impact of this new model of care using telemedicine on parent/guardian satisfaction, adherence rates to an evidence-based hip surveillance program, and economic efficiency.
This study will be the first study to use ischemic preconditioning (IPC) as an intervention to improve stroke rehabilitation. IPC is a well studied, well tolerated intervention which has been shown to improve regional blood flow, motor neuron excitability and muscle function in multiple patient groups and in young, healthy subjects. Because IPC targets three physiological systems which are all affected by stroke, we hypothesize that repeated bouts of IPC during the first days to months following stroke (when the majority of recovery occurs) will make traditional rehabilitation strategies more effective.
The purpose of this retrospective chart review pilot study is to research the results and scores of the QOL questionnaire implemented across Allina Health clinics. This study will investigate average QOL scores by clinical population and demographic group, the change in scores over time, and the effect of clinical interventions on QOL scores. The results will provide insight into QOL trends within different patient populations and provide guidance regarding optimal treatment plans so that Allina caregivers can positively impact patients' QOL.
The ERA Stroke project will compare the effects of robotic gait training (RGT) and usual care (UC) gait training in patients in the subacute phase of stroke recovery undergoing inpatient rehabilitation at the Baylor Scott \& White Institute for Rehabilitation (BSWIR).
The FIRST project compares the dose of robotic gait training (RGT) with usual care gait training for patients with spinal cord injury (SCI) undergoing rehabilitation at Baylor Scott \& White Institute for Rehabilitation (BSWIR).
This is a single-cohort early feasibility trial to determine whether an investigational device called the Bidirectional Neural Bypass System can lead to the restoration of movement and sensation in the hand and wrist of up to three individuals with tetraplegia.
To compare the results of the SOCS-OTS to another standardized screening measure that is currently being used by rehabilitation services at MD Anderson Cancer Center and to ensure that the SOCS-OTS correctly identifies those individuals needing OT services in cancer care.
The aging US population threatens to overwhelm our healthcare infrastructure, especially since the rate of Alzheimer's disease (AD) alone is expected to triple in the coming decades. Memory cause functional impairment, reduced quality of life, increased caregiver burnout, and eventual institutionalization. The diagnosis of mild cognitive impairment (MCI) identifies those with memory deficits but who remain relatively independent in everyday life. MCI provides a window for interventions that target memory functioning. The proposed study focuses specifically on a groundbreaking combination of mnemonic rehabilitation and non-invasive brain stimulation. The main idea is that brain stimulation can enhance functioning in the specific brain regions/networks, thereby increasing the patients' ability to benefit from different types of memory rehabilitation. This will be a randomized, double-blind study (active vs. fake brain stimulation), that provides multiple treatment session. Outcome will be examined using both laboratory-based and real-world memory testing as well as brain imaging. This first-of-its-kind study has the potential to meaningfully translate more "basic" science findings into neuroanatomically targeted and functionally meaningful treatments for our aging population.
Remembering how to travel from one location to another is critical in everyday life, yet this vital ability declines with normal aging and can be further affected by conditions that disproportionately affect the elderly, such as vision loss or progressive dementia. Human and animal research has shown that two distinct memory systems interact during navigation. The first, referred to as allocentric navigation, is very flexible and uses spatial knowledge of key features or landmarks to develop and use a mental map of the environment. This approach involves brain regions that are critical for new learning and memory but that decline with age. The second, referred to as egocentric navigation, is inflexible and relies on "habit" memories that link specific features with specific directions. This approach relies on brain regions that are critical for "automatic" responses and that are relatively unaffected by age. The main problem is that allocentric navigation declines with age and is accompanied increased dependence on egocentric navigation. This change increases the risk of becoming disoriented or "lost" when traveling in unfamiliar areas or even when traveling new routes in familiar areas. Therefore, the main goal of this project is to examine whether non-invasive brain stimulation, specifically transcranial direct current stimulation, can improve allocentric navigation in healthy older adults and patients with mild cognitive impairment. Participants will complete two functional magnetic resonance imaging sessions while learning new environments. Before one of these sessions, participants will receive active brain stimulation over the parietal cortex. Before the other session, participants will receive sham brain stimulation over the parietal cortex. The effects of this stimulation will be evaluated using both an allocentric and an egocentric memory test. Physiologic effects will be evaluated using both task-based and resting-state MRI.
It is well known that the motor area of one hemisphere of the brain (motor cortex) controls the movement of the opposite of the body. However, it is not clear whether as the movement becomes more complicated, the motor cortex of both hemispheres of the brain are involved. Currently the role of the motor cortex on the same side of the body (referred to as ipsilateral motor cortex) in hand performance remains controversial. The investigators demonstrated previously in healthy subjects that transiently lowering the activity of ipsilateral motor cortex improved the performance of the opposite hand. What is not know are the mechanisms involved in these changes of behavior. Transcranial magnetic stimulation (TMS) is a device that allows the non- invasive stimulation of the brain. When brain is stimulated repetitively at a very low rate and low intensity for about 15 minutes, the stimulated brain area becomes less active. This effect lasts 10 minutes and is called a "transient artificial lesion" as it mimicks the effects of transiently interfering with the function of the stimulated brain area. In the present study the investigators will conduct experiments using repetitive TMS to downregulate the activity of the motor area as in previous experiments and measures its effect on activity of motor cortex of both hemispheres. The investigators will study healthy subjects. It would be important to understand the effects in more detail for the design of treatment strategies in patients after stroke, which will be a topic of future studies.
As of 2020, 53 million Americans provide unpaid care to an individual with a disability. One commonly performed activity of daily living (ADL) provided by informal caregivers is assisted transfers, which requires moving an individual from one surface to another. Approximately 94% of informal caregivers who assist with ADLs to persons with adult-onset chronic physical disabilities affecting mobility reported musculoskeletal discomfort, with pain and discomfort made worse by performing caregiving activities. Although many informal caregivers assist with transfers, most have never received any formal training in proper manual lifting or mechanical lifting techniques. Improper transfer techniques can be detrimental to not only caregiver health but also to the persons they assist resulting in shoulder injury, bruising and pain from manual lift techniques, hip fractures from falls, and skin tears from shear force that occurs with sliding during transfers. Current standard of care provides limited in-person training of caregivers, as most of the rehabilitation process is client-focused. When training is provided clinicians have no means to objectively evaluate if proper techniques are being performed at discharge or when the caregiver and care recipient return home. For this reason, an outcome measure called the Caregiver Assisted Transfer Technique Instrument (CATT) was developed to provide a quick, objective way to evaluate proper technique of caregivers who provide transfer assistance to individuals with disabilities. The CATT evaluates the caregiver's performance on setup, quality of the task performance, and results. After a formal assessment through stakeholder review involving clinicians, informal caregivers, and individuals with physical disabilities who require transfer assistance, the CATT was expanded to include two versions; one that evaluates manual lift technique (CATT-M) and one that evaluates mechanical lift techniques (CATT-L). However, the CATT must undergo further testing with informal caregivers and the individuals they assist to determine if the CATT is a reliable, valid, and responsive tool for identifying skill deficits in caregivers performing assisted transfers. The purpose of this study is to establish the psychometric properties (reliability, validity, and responsiveness) of the CATT and to evaluate the effects of an individualized training session for participants who have transfer technique deficits as identified by the CATT. The long-term goal of this research is to develop the CATT so that it can be used as an objective indicator of transfer performance as well as guide training and educational interventions for informal caregivers to reduce the risk of musculoskeletal pain and injury associated with assisted transfers.
The research team will develop a novel training tool to improve finger joint coordination, to address the unmet need in the current rehabilitation, thereby enhancing hand function and contributing to improved independence and quality of life for Veterans with stroke.
This is an early feasibility trial to determine whether transcutaneous neuromuscular electrical stimulation, with or without transcutaneous spinal cord stimulation, using an investigational neurostimulation device improves functional arm/hand movements in individuals with paralysis or paresis due to a spinal cord injury or stroke and improves functional arm/hand or leg/foot movements in individuals with paralysis or paresis due to other brain or nerve injuries. In this study, eligible individuals that agree to participate will be asked to attend up to 5 study sessions a week for 1 year (depending on participant availability), with each session lasting up to 4 hours. At the first study session, participants will have their demographic information collected, vital signs assessed, and have measurements performed of their limbs and torso, as appropriate. They will also undergo clinical evaluations and tests to assess their current functional movement and sensation capabilities. During subsequent study sessions, participants will undergo many tasks designed to improve functional movements in paralyzed limbs. Specifically, participants will receive neuromuscular electrical stimulation to the limb(s) and/or electrical stimulation to the spinal cord to evoke specified movements. The stimulation parameters and locations on the spinal column and/or limb(s) that evoke specific movements will be noted. The movements will be assessed with visual inspection, electromyography, and/or sensors. The clinical evaluations and tests to assess functional movement and sensation capabilities will be repeated throughout the study and at the last study session to assess for functional improvements compared to the first study session. Upon completion of these study sessions, the individual's participation in the study is considered complete.
This epidemiologic research is being conducted as an observational prospective case series outcomes study of the use of advanced integrative specialty medical care and its effect on adult and pediatric patients with chronic or serious illnesses or mental health disorders.
Stroke is a leading cause of morbidity in the United States but identification of treatment strategies to improve outcome is limited by the incomplete understanding of the mechanisms of recovery. Motor cortex (M1) reorganization plays a major-role in the recovery of motor deficits post-stroke; hence the importance for further development of rehabilitative strategies that utilize this potential for recovery. In Specific Aim 1, investigators will determine if repeated exposure to training combined with Hebbian-type M1 stimulation enhances functional M1 reorganization in lesioned M1 of stroke patients. In Specific Aim 2, investigators will determine if repeated exposure to training combined with Hebbian-type M1 stimulation enhances structural cortical reorganization in lesioned M1 of stroke patients and to explore whether these structural changes are related to the training induced functional cortical reorganization. The overall goal of this project is to determine the effect of Hebbian- type stimulation on both, functional and structural brain reorganization, thereby obtaining indirect evidence for the neuronal substrate underlying training related improvement and maintenance of motor function in stroke patients. This knowledge may have a substantial positive impact on treatment for stroke patients that may significantly improve recovery and could move the field of neuro-rehabilitation forward.
The study is sponsored by the National Heart, Lung, and Blood Institute, which is part of the National Institutes of Health. We expect to enroll 400 subjects into this study. We will be recruiting research participants that are finishing or will finish cardiac rehabilitation soon. Participants belong to one or more groups of people who are less often studied in cardiac rehabilitation research, may have less access to a formal cardiac rehabilitation maintenance program, or they may especially benefit from additional support after cardiac rehabilitation ends. The main purposes of this study are to evaluate which treatments work the best after cardiac rehabilitation, which order to deliver the treatments in, and which treatments are as minimally burdensome as possible while still working well. This study will make two comparisons (one comparison between a set of low-intensity interventions and another between a set of higher-intensity interventions) to determine which produces the best behavioral adherence immediately after Phase II (outpatient) cardiac rehabilitation
The purpose of this study is to determine if an evidence based exercise intervention improves the functional mobility of diabetic amputees (single lower leg amputation) who have already completed standard rehabilitation and prosthetic training.
The purpose of this research study is to learn more about brain activity when individuals with and without Parkinson disease (PD) move their lower limbs. The investigators also want to see if and how two different types of partnered dance affect brain activity in individuals with and without PD. Testing will take place at the Atlanta VA Medical Center and at Emory University. The investigators expect to enroll about 140 people for this study over a five-year period.
The purpose of this study is to develop methods for studying the effect of bodywork therapy on symptoms of fatigue in patients undergoing cancer chemotherapy.
