114 Clinical Trials for Various Conditions
The study is about using a brain stimulation technique called rTMS (Repetitive Transcranial Magnetic Stimulation) to help improve hand muscles in people who had a stroke. Researchers want to understand how this device can help stroke patients use their hands better.
The purpose of this study is to see how well a treatment called "Repetitive Transcranial Magnetic Stimulation" works for patients who struggle with symptoms of both posttraumatic stress disorder and major depressive disorder.
This project will study 40 Veterans identified with symptoms understood to characterize mild to moderate Traumatic Brain Injury (TBI) including Post Traumatic Stress Disorder (PTSD). Following screening and informed consent, Veterans will be randomly assigned to treatment with repetitive Transcranial Magnetic Stimulation (rTMS) or sham rTMS (placebo). Additional examinations will compare brain imaging (structural and functional MRI scans at rest) across participants at baseline, after acute rTMS treatment, and at 6 month followup. The VA population differs significantly from populations that have been included in prior trials of rTMS for many conditions such as depression, chronic pain, and PTSD. Many returning Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) personnel and Veterans with concussion histories report cognitive problems, such as impaired attention, verbal fluency, poor planning, reduced working memory, and mental flexibility. The investigators hope to show the efficacy and durability of rTMS in treating these symptoms safely in Veterans with co-morbidities.
The purpose of this study is to determine whether the combination of low frequency repetitive transcranial magnetic stimulation (rTMS) and motor-imagery-based brain computer interface (BCI) training is effective for enhancing motor recovery after stroke. The PI's hypothesis is that, in comparison with traditional physical therapy alone, subjects receiving supplementary rTMS and BCI training will show greater functional improvements in hand motor ability over time as well as recovery of normal motor connectivity patterns.
The purpose of this multi-site trial is to determine if repetitive Transcranial Magnetic Stimulation (rTMS) helps people with depression who have not been helped by medications or who have not been helped enough by medications.
The purpose of this study is to examine whether repetitive transcranial magnetic stimulation (rTMS) can be used to improve speech in chronic stroke patients with aphasia. Aphasia patients can have problems with speech production. The rTMS procedure allows painless, noninvasive stimulation of human cortex from outside the head. Chronic aphasia patients have been observed in our functional magnetic resonance brain imaging studies to have excess brain activation in brain areas possibly related to language on the right side of the brain (opposite side to where the stroke took place). It is expected that suppression of activity in the directly targeted brain region will have an overall modulating effect on the neural network for naming (and propositional speech) and will result in behavioral improvement.
The goal of this clinical trial is to learn if using deep repetitive transcranial magnetic stimulation (rTMS) targeting the precuneus is feasible, tolerable, and potentially efficacious for memory in Probable Alzheimer's Dementia. Previous work studying rTMS in Alzheimer's is mixed, but recent work studying rTMS of the precuneus is encouraging for both its short-term and long-term effects. The main questions this study aims to answer are: * Is deep rTMS of the precuneus feasible and tolerable in Alzheimer's? * Are there signs of positive brain changes in response to deep rTMS? * Is deep rTMS potentially efficacious for memory in Alzheimer's? Researchers will compare active stimulation to placebo stimulation while obtaining memory testing and measurements of the brain (imaging, scalp electrode measurements, bloodwork) to see if active treatment works to treat mild-to-moderate probable Alzheimer's Dementia. Participants will: * Engage with memory testing, brain scans, and bloodwork during a comprehensive assessment * Visit the clinic 3 times for 12 consolidated rTMS sessions, followed by 4 once weekly maintenance sessions * Be offered a full open-label active treatment course after completing their treatment course if they are initially in the placebo group
A prospective study to evaluate symptoms following repetitive transcranial Magnetic stimulation.
This study aims to assess the efficacy of Personalized Repetitive Transcranial Magnetic Stimulation (PrTMS) therapy to reduce chronic neck for military health system beneficiaries.
This study aims to examine the long-term effect of repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation technique, on chronic headaches following mild traumatic brain injury (mTBI). rTMS has been shown to be effective in reducing chronic headaches without side effects commonly seen in medications, such as sleepiness and addiction. This study uses rTMS to manage chronic headaches to improve post-concussion symptoms and reduce the economic burden due to delayed recovery. This project aims to better identify biomarkers for diagnosis and prognosis and maximize recovery from mTBI.
Veterans with comorbid chronic pain and depression are highly prevalent, have poor functional status and low quality of life, are at increased risk of suicide and lack access to effective treatments. To address this problem, the proposed research will examine the feasibility of a novel approach that integrates repetitive Transcranial Magnetic Stimulation and Acceptance and Commitment Therapy with the overall goal of maximizing functional improvement in Veterans with chronic pain and depression. This is an important first-step in preparation for a future randomized efficacy trial. The investigators will also include two cognitive control tasks with concurrent electroencephalography to explore as a potential objective indicator of treatment response. This application addresses a critical need within the Veterans Health Administration and is closely aligned with the focus area of developing suicide prevention treatments that influence participation in life roles.
This is a research study to evaluate the safety, efficacy and feasibility of high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) in patients with subacute spinal cord injury.
The Repetitive Transcranial Magnetic Stimulation (rTMS) is a type of brain stimulation that uses a magnet to change activity in the brain. rTMS uses magnetic pulses to induce an electrical current in the brain to alter brain activity and function in specific areas. For example, stimulating the part of the brain controlling movement will cause parts of the foot or leg to twitch. TMS is proposed as a novel treatment for people with schizophrenia. The investigators want to see if low frequency rTMS can lessen some of the symptoms of schizophrenia, specifically auditory verbal hallucinations. Auditory verbal hallucinations describe the experience of hearing voices that are not really there.
Overactive bladder (OAB) affects an estimated 16-30% of women in the US and urgency urinary incontinence (UUI) affects 7-11% of women with OAB. It is known that repetitive transcranial magnetic stimulation (rTMS) over the supplementary motor area (SMA) can modulate the pelvic floor muscle activity with potential benefits for various urologic conditions. The goal of this study is to assess feasibility of rTMS as a treatment option for OAB with UUI by determining which rTMS frequency is most effective in targeting sensory components of OAB, namely urinary urgency, and also in targeting the brain network known to be involved in OAB.
The purpose of this research study is to test the effect of repetitive transcranial magnetic stimulation (rTMS) on opioid cravings among adult patients with Opioid Use Disorder.
We propose a single-arm clinical trial, with historical controls as a comparison group for select outcomes. Subjects with MAUD will receive 16 sessions of dual-target theta burst stimulation to the DLPFC and MPFC over 4 weeks. We will follow outcomes for 12 weeks. Outcomes include treatment retention, craving, self-reported MA or stimulant use, urine drug screen results, depressive symptoms, anxiety symptoms, sleep quality, quality of life, response inhibition, and functional connectivity. Magnetic resonance imaging (MRI) to measure functional connectivity at baseline and four weeks.
The primary purpose of this study was to conduct fMRI neuroimaging studies prior to and subsequent to the rTMS intervention. The intent was to ascertain changes in regional brain activation and connectivity that most robustly predict level of improvement in auditory hallucinations elicited by bilateral rTMS as assessed by the primary outcome variables.
Investigating the efficacy of a form of TMS called theta-burst stimulation for restricted and repetitive behavior in ASD.
The study will include subjects diagnosed with Dystonic Tremor (DT), Essential Tremor (ET), and healthy controls in the age range of 21-80 years. Electroencephalography (EEG) will be used as the primary outcome measure. Transcranial Magnetic Stimulation (TMS) will be used over the motor cortices or cerebellar cortices as an intervention that is expected to have short-term (less than an hour) electrophysiological effects.
The purpose of this study is to establish a new treatment (repetitive transcranial stimulation (rTMS)) for Veterans with stimulant use disorder (SUD). Despite the large public health burden imposed by SUD, there is currently no FDA-approved or widely recognized effective somatic treatment. rTMS may be a promising treatment option for SUD. In this study, we will demonstrate the feasibility of applying rTMS to Veterans with SUD, examine the efficacy of rTMS in the treatment of SUD, and explore biomarkers that may guide patient selection for rTMS treatment and predict treatment response.
The purpose of this study is to understand the role of repetitive Transcranial Magnetic Stimulation (rTMS) in reducing opioid and other substance use and craving and improving thinking skills.
This will be a single site pilot study. 16 subjects with early phase psychosis (EPP), defined as medical record documentation of the onset of clinically significant psychotic symptoms within the past ten years, will be randomized 1:1 to double-blind treatment with 5 sessions of rTMS or sham stimulation directed at the bilateral precuneus over the course of 1 week. Subjects will undergo functional magnetic resonance imaging (fMRI) procedures, behavioral and cognitive assessments, and self-referential memory paradigm (SRMP) at baseline and immediately following the final rTMS or sham session. Contact with subjects will be conducted at two weeks after the end of study intervention for adverse event assessments. In the event new adverse events felt to be related to the study intervention have occurred following the termination of study procedures, subjects will be brought in for further safety assessments.
Chronic low back pain (CLBP) is a common reason for which patients are treated with opioids. Because the misuse of prescription opioids has become a serious problem in the Uinted States, finding effective alternative non-pharmaceutical interventions for chronic pain management has become an urgent matter. A phenomenon termed central sensitization (i.e. mal-adaption of the brain) has been hypothesized to be an underlying mechanism for the development of chronic pain, leading to sensory hypersensitivity to extremal stimuli. Therefore, non-invasive brain stimulation, such as repetitive transcranial magnetic stimulation (rTMS) may be an effective intervention to regulate brain excitability, thus reducing chronic pain. However, research has shown inconclusive evidence regarding the rTMS effects on chronic pain reduction, partly due to the heterogeneity of participants in studies to date. Therefore, the primary purpose of this study is to investigate the immediate and short-term effects of rTMS on neurosensory changes (i.e., pain thresholds) in patients with CLBP. The secondary purpuse of the study is to explore the relationship between changes of cortical excitability (TMS parameters) and changes of pain thresholds after the rTMS intervention in patients with CLBP.
The ultimate goal of this study is to develop non-invasive, painless repetitive transcranial magnetic stimulation (rTMS) protocols to prevent cognitive decline in patients with mild cognitive impairment (MCI) and cognitively normal individuals at high risk of developing Alzheimer's disease (AD). Currently, 1 in 9 adults over the age of 65 have AD, which currently totals more than 5 million Americans and this number is expected to rise as high as 16 million by 2050. MCI is a clinical syndrome that represents the gray area between healthy aging and dementia. Those with amnestic MCI (aMCI) have memory problems more severe than normal for their age and education, but their symptoms are not as severe as those of people with AD. Patients with aMCI are at high risk for AD. Notably, roughly half of those with MCI will continue to progress and convert to clinical dementia within 3 years. Alternatively, it is also worthwhile to study cognitively healthy older adults who carry genes that may increase the risk of AD. The frequency of the human APOE gene ε4 allele increases in patients with AD and the ε4 allele is also associated with an earlier age of disease onset. Currently, there are no known therapies that can effectively modify the progression and hallmark symptoms of AD. Therefore, it is crucial to provide an early intervention in patients with aMCI to delay or prevent the progression to AD. More specifically, this project has two specific aims: 1. To plan personalized non-invasive brain stimulation location by brain Imaging with Magnetic Resonance Imaging (MRI) in Mild Cognitive Impairment (MCI) 2. To identify potential personalized cognitive enhancement strategy (such as dosage or patterns) of Transcranial Magnetic Stimulation (TMS) in MCI. Techniques to artificially and precisely stimulate brain tissue are increasingly recognized as valuable tools both in clinical practice and in cognitive neuroscience studies among healthy individuals and people with clinical conditions. With these practices, researchers can safely stimulate specific regions of the brain to explore causal relationships that comprise the brain's circuitry and modulate behavior.
The objective of the current study is to investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on self-reported negative affect, cerebellar brain activation and alcohol use outcomes in alcohol use disorder (AUD).
The proposed study will evaluate the safety, durability and efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a promising non-invasive therapeutic treatment for improving memory in older adults with mild or moderate Traumatic Brain Injury (TBI) who have been experiencing residual memory or cognitive problems that affect daily functioning.
This trial studies how well navigated repetitive transcranial magnetic stimulation works in improving motor rehabilitation in participants with brain tumors. Navigated repetitive transcranial magnetic stimulation may help improve patients' lost motor function after surgery.
This double-blind, randomized, controlled trials will investigate the effect of accelerated, repeated transcranial magnetic stimulation on opiate craving and perceived pain .
The Researchers are going to gather information regarding the use of rTMS as a treatment for depression in adolescents with Major Depressive Disorder. The researchers also hope to learn if measures of brain activity (cortical excitability and inhibition) collected with transcranial magnetic stimulation (TMS) can be used to identify which patients will benefit from certain types of rTMS treatment.
Persistent headache is one of the most common debilitating symptoms in military personnel suffering from mild traumatic brain injury (MTBI). This study aims to assess the long-term effect of repetitive transcranial magnetic stimulation (rTMS) in managing MTBI related headaches for up to 2-3 months by comparing the treatment effect of active-rTMS to sham-rTMS.
