Hand disability after stroke has a profound negative impact on functional ability and independence. Hand therapy may be augmented with sensory stimulation for better outcomes. We have developed a novel sensory stimulation - unfelt vibration applied via a wristwatch. In this study, we will determine if combining this stimulation with hand task practice is superior to hand task practice alone.
Post-stroke hand impairment diminishes stroke survivors' ability to perform activities of daily living. Motor recovery has been shown to improve through peripheral sensory stimulation. This study aims to determine if vibration from a smartwatch improves post-stroke hand function.
The objective is to determine if continuous use of TheraBracelet in the home has a clinically meaningful effect in chronic stroke survivors. The study design is a double-blinded randomized controlled trial. We will enroll 40 chronic stroke survivors with moderate hand impairment. Subjects will be randomly assigned to the treatment or control group (n=20 per group). All subjects will wear the TheraBracelet device on the paretic wrist for 8 hours/day every day during their normal daily activity for 1 month. The device will deliver vibration (treatment) or no vibration (control). Double-blinding is possible because the treatment vibration is imperceptible (i.e., subthreshold). Measures of neural plasticity, the amount of the paretic arm use in daily living, clinical hand function, biomechanical grip control, and self-reported abilities for activities of daily living will be assessed at baseline, once a week during the month of wearing the device, and for 3-month follow-up, allowing determination of the efficacy and persistence.
The purpose of this study is to evaluate the safety and effectiveness of daxibotulinumtoxinA for injection (a new investigational study drug) compared to placebo in the treatment of cervical dystonia (CD). DaxibotulinumtoxinA for injection is composed of purified botulinum toxin type A, formulated with a small protein RTP004, and will be used for injection.
If you are eligible and choose to be in the study, the dose of study drug you receive (125 units or 250 units) will depend on your clinical assessment, the severity of your disease, and whether you have had any toxin before.
The study may last up to 55 weeks, including 3 weeks of screening. You will come to the study center up to 15 times.
The study is being done at approximately 80 sites. Approximately 290 adults with moderate to severe isolated CD, who are 18-80 will take part study-wide and 4 will take part at this institution.
The purpose of this study is to evaluate the safety and effectiveness of daxibotulinumtoxinA for injection (a new investigational study drug) compared to placebo in the treatment of cervical dystonia (CD). DaxibotulinumtoxinA for injection is composed of purified botulinum toxin type A, formulated with a small protein RTP004, and will be used for injection. Placebo means it doesn't contain botulinum toxin type A.
If you are eligible and choose to be in the study, the dose of study drug you receive will depend on the group that you will be put into after randomization at the time of your entry.
You will be assigned, by chance, to 1 of the 3 groups below:
? Group 1: High-dose (250 Units of daxibotulinumtoxinA for injection)
? Group 2: Low-dose (125 Units of daxibotulinumtoxinA for injection)
? Group 3: Placebo (a substance that looks like daxibotulinumtoxinA for injection but has no drug in it)
Study lasts aproximately 39 weeks, including 3 weeks of screening. You will come to the study center up to 12 times during the research study.
The study is being done at approximately 80 sites. Approximately 300 people will take part study-wide and 4 will take part at this institution.
Walking after a lower extremity amputation is often difficult. It is important that researchers and clinicians understand the mechanisms that inhibit normal walking function. In this study, we are recruiting individuals with lower extremity limb loss for a walking and balance investigation. We will also be studying matched healthy controls to do similar study procedures. All study procedures will occur on the campus of MUSC by a licensed Physical Therapist and experienced researcher. Any questions should be directed to the coordinator listed.
Transcranial direct current stimulation (tDCS) has shown the potential to improve symptoms in patients with motor deficits, however its effects have not been consistent in randomized studies to date, limiting widespread adoption of this technology. A critical gap in our knowledge is a detailed understanding of how tDCS affects motor areas in the brain. We propose using tDCS while recording directly from motor cortex using subdural electrocorticography (sECoG) in patients undergoing deep brain stimulation surgery. We expect this novel approach to broaden our understanding of tDCS application and possibly lead to therapeutic advances in this population.
This research studies the effects of brain stimulation (transcranial magnetic stimulation, or "TMS") on balance in progressive supranuclear palsy (PSP). The purpose of this research is to look for improvements in balance when subjects are on a tilting platform after stimulating the brain with a magnetic wand held over the scalp over an area at the back of the brain called the cerebellum. Participants will receive both active and inactive stimulation during the course of the study. There is no surgery involved. There are also optional portions of the study that include functional magnetic resonance imaging (fMRIs) and speaking samples.
The purpose of this study is to determine if a drug called Nilotinib is safe, if it can be tolerated by patients with PD and to learn if Nilotinib has the possibility of effectively treating PD symptoms. Nilotinib has been approved by the Food and Drug Administration (FDA) to treat certain types of cancer (leukemia) but is considered investigational in this study because it has not been approved for treating PD.
In this study, we are comparing two doses (150mg or 300mg) of Nilotinib to placebo (a pill that looks like the study drug but does not have any active medication in it, like a sugar pill). If you are eligible and choose to be in the study you will be randomly assigned to one of three groups, either:
? 150mg Nilotinib
? 300mg Nilotinib
All three groups will take two pills of the assigned type each day by mouth. ?Randomly' means that the group you are placed in is determined by chance (like tossing a coin). You will have a 2:1 chance of receiving Nilotinib. Neither you nor the researchers will know whether you are taking Nilotinib or placebo.
About 100 individuals will be interviewed and assessed, and 75 people will be asked to participate in this study at 25 clinics across the United States. Approximately 6 participants will be asked to participate in the study at MUSC.
You are invited to volunteer for a research study if you have been diagnosed with Amyotrophic Lateral Sclerosis (ALS) within 2 years (24 Months) prior to screening.
This is a non interventional, longitudinal study in patients with ALS. There will be four (4) subject visits in this study: Baseline, month 6, month 12, and month 18. Subjects will have blood and cerebrospinal fluid (a clear fluid found in your brain and spine) collected, and be evaluated with assessment tools that focus on upper and lower motor skills and strength as well as cognitive function. Researchers will use these samples to study ALS, motor neuron disease and other medical conditions.
