417 Clinical Trials for Various Conditions
This multi-site clinical trial aims to assess the efficacy and safety of combining peripheral nerve stimulation with local anesthetic nerve blockade compared to the standard of care, i.e., local anesthetic blockade only using safe stimulation parameters in a condition associated with high postoperative pain state, i.e. a patient undergoing lower limb amputation.
This pilot study investigates the regular use of non-invasive dorsal genital nerve stimulation (DGS) for the treatment of female sexual dysfunction (FSD). The researchers aim to determine whether subjects with FSD can correctly follow an at-home treatment regimen and to demonstrate that DGS can improve FSD arousal symptoms in premenopausal and postmenopausal women.
Patients with Group 1 pulmonary hypertension will be enrolled in this study. Investigators will test the hypothesis of low-level tragal stimulation in patients with pulmonary hypertension. The study will be conducted over 4 weeks and patients will undergo low-level tragus stimulation for 1 hour every day for 4 weeks. At baseline the following tests will be conducted-6-minute walk distance, vascular function testing using noninvasive device and blood samples will be collected. Patient will also undergo a limited echocardiography to assess right ventricular function. After 4 weeks of stimulation patients will come back to undergo these tests again. Investigators hypothesized that low-level tragus stimulation (neuromodulation) will lead to improvement in vascular function, 6-minute walk distance and blood based biomarkers in patients with pulmonary hypertension.
This study is being done to test whether low-intensity focused ultrasound (LIFU) (low energy sound waves) cause temporary changes in brain activity and behavior when directed at particular parts of the brain. By targeting LIFU to the parts of the brain thought to be responsible for essential tremor (ET), and measuring any associated improvement in tremor, the investigators hope to show that LIFU can be a useful tool for studying the brain circuits responsible for tremor and other brain disorders.
Investigators are conducting this study to test if temporarily and non-invasively stimulating the brain will affect the emotional response to stress in healthy participants. Participants will perform a series of tasks while completing an MRI scan. After this, participants will be randomized to undergo transcranial magnetic stimulation (TMS) at two visits, undergoing active stimulation at one visit and undergoing 'sham' stimulation at another visit. Immediately following both stimulation sessions, participants will repeat the tasks during MRI scanning.
We will recruit 10 patients with OCD meeting established criteria for surgical evaluation. Following informed consent and baseline evaluations, each will be implanted with permanent DBS SenSight leads and the Medtronic Percept RC IPG, which has on-device neural recording capability and rechargeability. We will collect a broad array of neurobehavioral data across two environments with complementary advantages: the clinic and the home. The first 2 Aims test our mechanistic hypothesis by studying the pattern of VS neural activity in the controlled environment of the lab/clinic during two complementary paradigms: one based on a psychophysical behavioral task, the other based on ERP, a therapeutic behavioral intervention. The third aim tests this hypothesis in an ambulatory, naturalistic setting with chronic neural on-device recordings paired with time resolved behavioral measures. We will investigate a possible common neural basis underlying approach and avoidance across these 3 paradigms. Subjects will participate in research at 7 critical timepoints during routine clinic visits (Fig. 4): before implant, 1 day before DBS activation, immediately after DBS activation, 2 weeks, 3 months, 6 months, and 12 months after DBS initiation. At these timepoints, patients will complete clinical assessments, perform the Probabilistic Approach Avoidance Task (PAAT), and conduct exposure trials under the guidance of a psychologist. The clinic offers the most controlled environment and provides opportunities for collecting high temporal resolution behavior synchronized to local field potential (LFP) recordings. These data will allow us to identify the degree of overlap in the time-resolved neural activity driving individual decisions to approach potential rewards or avoid potential aversive stimuli (Aim 1), and resist performing compulsions in order to achieve relief after OCD symptoms are triggered (Aim 2). At home, our goal is to investigate patient trajectories along the approach-avoidance axis as OCD symptoms improve (Aim 3). We will leverage passive, on device recordings that occur in the background of everyday life activities and synchronize these neural recordings with data collected via wearables, ecological assessments, and video diaries. Capturing neural and behavioral data in the home environment is essential for understanding the neural and behavioral changes that occur over longer timescales than individual clinical visits. The neurobehavioral biomarkers generated by this dataset will provide trackable readouts of clinical status that could inform therapeutic decision-making and enable data driven intervention.
Spasticity is characterized by increased muscle tension and is a classic consequence of upper motor neuron (UMN) damage in the central nervous system, such as from stroke or trauma. Clinically, it presents as muscle resistance to passive stretching, along with clasp-knife rigidity, clonus, increased tendon reflexes, and muscle spasms. An imbalance of the descending inhibitory and muscle stretch reflexes is thought to be the cause of spasticity. Post-stroke spasticity is a common condition that occurs in 37.5-45% of cases in the acute stage and 19-57.4% in the subacute stage after a stroke. At 6 months post-stroke, spasticity develops in 42.6-49.5% of cases, and at one year, it affects 35-57.4% of individuals. In patients with cerebral palsy (CP), incidence is almost 80% while in those living with spinal cord injury the number approaches up to 93%. Traumatic brain injury (TBI) patients have a higher prevalence on initial admission to neurorehabilitation but one in three patients will have chronic spasticity. However, the Defense and Veterans Brain Injury Center report a rate of TBIs amongst deployed veterans to be around 11-23% mostly from blast and explosive trauma. There have been studies as early as the 1980s exploring the efficacy of SCS for spasticity control, however, the credibility of many of these studies is constrained due to an incomplete comprehension of spasticity's underlying mechanisms, outdated research methods, and early limitations in implantable device technology. Intrathecal pumps for baclofen have remained as the mainstay for refractory spasticity, however, it comes with associated risks such as chemical dependence leading to acute baclofen withdrawal and requiring frequent refill requirement. Most importantly, it does not yield functional improvement of muscle activity, just suppression of spasticity. Botox is also routinely used but due to heterogeneity in muscle involvement as well as variability in provider skill, results may be inconsistent and short-lasting, requiring frequent clinic visits for repeat injections to the affected muscle groups. SCS may be able to address that gap in spasticity management.
People with spinal cord injuries may experience muscle tightness or uncontrollable spasms. This study is being conducted to investigate whether transcutaneous spinal stimulation can improve these symptoms. Transcutaneous spinal stimulation is a non-surgical intervention by applying electrical currents using skin electrodes over the lower back and belly. The investigators want to see how well the intervention of transcutaneous spinal stimulation performs by testing different levels of stimulation pulse rates. Also, transcutaneous spinal stimulation is compared to muscle relaxants such as baclofen and tizanidine, commonly given to people with spinal cord injuries, to reduce muscle stiffness and spasms. By doing this, the investigators hope to discover if transcutaneous spinal stimulation similarly reduces muscle spasms and stiffness or if combining both methods works best. This could help improve treatment options for people with spinal cord injuries in the future.
Fibromyalgia (FM) is a chronic disorder that affects the musculoskeletal system, causing widespread pain, tenderness, and fatigue. It is estimated to affect 1-5% of the population. The primary symptom of fibromyalgia is widespread pain throughout the body, accompanied by tenderness and sensitivity to pressure. Pharmacological treatments include drugs such as antidepressants, anticonvulsants, and painkillers. Another treatment option for fibromyalgia is the use of devices such as Quell. Other non-pharmacological treatment options for fibromyalgia include cognitive-behavioral therapy (CBT), biofeedback, and relaxation techniques. Remote Electrical Neuromodulation (REN) is a non-pharmacological technology that induces subthreshold, non-painful neurostimulation signals that activate an endogenic pain-management system termed Conditioned Pain Modulation (CPM), to produce generalized pain relief in remote body areas. Multiple studies have shown that REN is safe and effective for the acute treatment of migraine in adults and adolescents, as well as migraine prevention. The current study examines the safety and efficacy of REN technology, implemented via the FibroNova device for treating fibromyalgia pain and related symptoms.
Post-intensive care syndrome (PICS) encompasses persistent physical, cognitive, and psychiatric symptoms following ICU discharge, commonly triggered by serious conditions such as respiratory failure, sepsis, and mechanical ventilation. PICS prevalence is reported to be as high as 84% up to 12 months in patients with at least 2 days spent in the ICU or with mechanical ventilatory support. As a consequence, many patients do not return to they former level of function for weeks, months and even years. Muscular affection manifested by muscle weakness is particularly seen and is provoked by a combination of damage to the nerves or directly the muscles fibers. This affection is referred to as CU-Acquired Weakness (ICUAW). One third of the time, lower extremities are affected, often due to prolonged immobilization or sedation. Evidence suggests that early mobilization reduces the incidence of ICUAW at discharge and improves the number of patients able of stand. However achieving this early intervention is not always feasible due to time or personnel constraints. The purpose of the study is to examine the effectiveness of lower extremity neuromodulation for prevention of muscle deconditioning in patients admitted to the ICU.
It has been demonstrated that the human lumbosacral spinal cord can be neuromodulated with epidural (ESS) and transcutaneous (TSS) spinal cord stimulation to enable recovery of standing and volitional control of the lower limbs after complete motor paralysis due to spinal cord injury (SCI). The work proposed herein will examine and identify distinct electrophysiological mechanisms underlying transcutaneous spinal stimulation (TSS) and epidural spinal stimulation (ESS) to define how these approaches determine the ability to maintain self-assisted standing after SCI.
The purpose of this study is to: 1. Development of culturally sensitive videos for enhance informed consent with neurostimulation and determination of factors that influence minority interest in participating in neurostimulation research. 2. Examination of the influence that video enhanced informed consent has on expectations with transcutaneous auricular vagus nerve stimulation (taVNS) and on treatment intended effects.
The primary goal of this clinical trial is to evaluate whether Personalized Augmented Cognitive Training (PACT) plus intermittent theta burst stimulation (iTBS) is effective for treating depression in Service Members, Veterans, and civilians who have sustained a mild TBI. Participants will receive PACT plus 20 sessions of iTBS or sham iTBS over 4 weeks. Assessments will occur at baseline, 2 weeks, 4 weeks, and 8 weeks. Researchers will compare the PACT+iTBS group to the PACT+sham iTBS group to see if PACT+iTBS is associated with more depression improvement.
This study will comprehensively investigate the insula as a brain target for neuromodulation to treat chronic neuropathic pain.
This is a prospective, multi-center, sham-controlled study comparing the safety and effectiveness of the self-adjusting, surgery-free, wearable Active System to a Sham System on adult Subjects diagnosed with OAB.
The purpose of the study is to examine the feasibility and potential efficacy of low-intensity focused ultrasound as a method of modulating amygdala function to promote improvements in symptoms of an affective disorder. Ultrasound is frequently and safely utilized for diagnostic purposes. In this study, the investigators will utilize magnetic resonance imaging (MRI) and neuronavigation to target the left amygdala and apply ultrasound. This will be conducted once a day, 5 days a week, for 3 weeks. This will be an open-label, single-arm trial.
This is an open label prospective pilot study of two neuromodulation interventions for patients suffering from dysphoria. Dysphoria is a transdiagnostic symptom of unease or dissatisfaction experienced across a range of diagnoses, including mood disorders and pain. There is a significant gap of treatment options across conditions with dysphoria, particularly non-medicated and self-care alternatives. Many neuromodulation therapies require extensive medical resources or time to deliver. Thus, the investigators will test two non-invasive technologies administered in a manner that would reduce resources and/or time. Virtual Reality (VR) overlays the sensory system to block the external environment and provide vast range of meaningful sensory experiences. Transcranial Magnetic Stimulation (TMS) involves a magnetic pulse passing through the scalp to depolarize neurons in the outer cortex of the brain, and daily treatments over 6 weeks are currently FDA indicated for the treatment of major depressive disorder. Accelerated TMS is the delivery of treatment in a shorter period of time. The primary objective of this study to demonstrate the preliminary effectiveness, tolerability, and feasibility of these two interventions: Guided Meditation VR for Wellness and Accelerated Transcranial Magnetic Stimulation.
This project is aimed at the discovery of neuro-modulation techniques that may alleviate chemotherapy induced cognitive deficits (CICD), especially in executive (higher-order) cognitive function (EF).
The purpose of this study is to assess the extent to which a non-invasive, palpatory neuromodulatory protocol on the trigeminal nerve endings on the face can affect tenderness felt on the posterior neck musculature, using the Isotouch pressure sensor system. Specific Aim 1: Subjects will see a decrease in tenderness in the posterior neck musculature. Specific Aim 2: Subjects will show a decrease in tenderness on the trigeminal tender points found on the face.
This is a phase 1 study of safety and feasibility of cervical spinal cord stimulator implantation in cervical SCI subjects who are ventilator dependent. The Investigators will be focusing on the safety and feasibility of this approach. Participants may qualify for the study if they are male or female 18-75 years old, are at least 1 year after original injury, have injury at C2 to C7 level, and dependent on mechanical ventilation to help them breathe. Additionally, they need to be able to attend up to twice weekly testing sessions for up to 21 months.
The objectives of this VA SPiRE application are to develop a combined neuromodulation and yoga (iTBS+yoga) intervention for Veterans with mild traumatic brain injury (mTBI) and chronic pain, assess the intervention's feasibility and acceptability, and to gather preliminary clinical outcome data on quality of life, function and pain that will guide future studies. This SPiRE project will directly benefit Veterans and VA Services by developing a new, non-pharmacological neurorehabilitation treatment for Veterans with mTBI and chronic pain in need of non-opioid treatment options. Neuromodulation is now offered at 30 VA hospitals and yoga is among the complementary and integrative health programs being rolled out as a part of VAs Whole Health implementation efforts. Thus, should iTBS+yoga ultimately prove to be efficacious, VA facilities will be well-poised to offer this treatment. A novel, activity-based, non-pharmacological treatment for Veterans with mTBI and chronic pain is of great need given the high prevalence of chronic pain.
Up to 40% of stroke survivors suffer from aphasia, making recovery of language abilities a top priority in stroke rehabilitation. Conventional speech and language therapy may have limited effectiveness. Leveraging multimodal data (behavioral, neuroimaging, and genetics), this study aims to 1) evaluate the efficacy of combining tDCS with speech therapy, 2) examine neural changes associated with recovery, 3) identify factors influencing response to treatment.
This multi-site, double-blind, randomized, sham-controlled mechanistic trial aims to test the effects of Magnus Neuromodulation System (MNS) with Stanford Accelerated Intermittent Neuromodulation Therapy (SAINT®) Technology on the neural circuitry of suicidal cognitions in psychiatrically hospitalized patients with Major Depressive Disorder (MDD) and active suicidal ideation (SI). This will be accomplished by applying the MNS with SAINT to a customized target within the left dorsolateral prefrontal cortex (L-DLPFC) identified with fMRI for five consecutive days and measuring resting-state functional connectivity (RS FC) between the subgenual anterior cingulate cortex (sgACC) and the default mode network (DMN) at baseline and immediate-post visit. The relationship between changes in RS FC and changes in both Explicit and Implicit Suicidal Cognitions (ESC and ISC, respectively) will be determined. This study will also determine the relationship between changes in RS FC in neural networks underlying mediators of suicidal cognitions and changes in such mediators with active versus sham SAINT.
Emerging neuroimaging studies have shown that the cerebellum contributes to different aspects of timing, prediction, learning, and extinction of conditioned responses to aversive stimuli, factors that may be relevant to the success of exposure based behavioral therapy. Our goals are to determine the cerebellar contributions to fear extinction by attempting to modulate key pathways in this process by theta burst stimulation. The long term goal is to lay the foundation for future studies in which neuromodulation is used to augment exposure therapy.
This is a prospective, randomized, controlled, multi-center, study in which 150 evaluable subjects will be randomized 1:1 to receive either a Protect CAN-Stim or SNS InterStim® system. Subjects from both groups will immediately start with therapy. The primary endpoint is a ≥ 50% reduction in number of incontinence episodes associated with urgency at the 3-month visit, with additional measurements assessed at 14 days, 1, 6, 9 and 12-months.
The purpose of this study is to test the use of a clinical decision support tool for postoperative care of Parkinson's disease patients who are treated using deep brain stimulation (DBS). The central hypothesis is that the use of a DBS clinical decision support system for individual patient management will enable considerable time savings and reduced burden on patients and caregivers.
