NCT05537597
Pain is an increasingly recognized non-motor symptom of Parkinson's disease (PD), with significant prevalence and negative impact on the quality of life of patients. Repetitive transcranial magnetic stimulation (rTMS) of the primary motor cortex（M1）has been proposed to provide definite analgesic effect for pain syndromes. However, very few placebo-controlled studies have been performed specifically to relieve pain in PD. What's more, based on behavioral measures alone, it is impossible to reveal the full network dynamics reflecting the impact of TMS. Electroencephalography (EEG), with high temporal resolution, records signal that its origin in electrical neural activity, which makes it suitable for measuring TMS-evoked activation. By recording the TMS induced neuronal activation directly from the cortex, TMS-EEG provides information on the excitability, effective connectivity of cortical area, thus exploring cortical network properties in different functional brain states. In addition, the use of EEG offers great prospects as a tool to select the right patients in order to achieve adequate, long-term pain relief. Besides assessing the efficacy and safety of high-frequency neuronavigated M1-rTMS in PD patients with musculoskeletal pain, the objective of this study additionally aimed to characterize cortical activation behind pain relief. Influence on motor and other non-motor symptoms after rTMS were also investigated.
NCT05998018
This prospective, multi-center, randomized, controlled clinical trial is being conducted to evaluate the safety and efficacy of the pdSTIM System to facilitate weaning from mechanical ventilation through phrenic nerve stimulation. Potential subjects who are on mechanical ventilation for at least four days and have failed at least one weaning attempt will be considered for the study. Those enrolled will be randomized in a 1:1 manner between the treatment group that is standard of care with the pdSTIM System and a Control group, which is standard of care alone.
NCT07217080
The thalamus plays a key role in supporting sleep and is also a target of therapeutic stimulation. This project investigates when, where, and how electrical stimulation delivered to the thalamus in humans elicits or disrupts sleep oscillations. This research is a first step to better understand how current neuromodulation therapies affect sleep and may help advance toward new therapies to improve sleep for a wide range of neurological and neuropsychological disorders.
NCT06852781
Shoulder pain is a musculoskeletal system (MSS) disease that is frequently seen in adults and tends to become chronic. It ranks 3rd among MSS diseases after low back and knee pain. The main causes of shoulder pain are compression syndromes, acromioclavicular (AC) and glenohumeral joint degeneration, adhesive capsulitis, and biceps tendinopathy. Pathology may be in the joint, bone, muscle, tendon ligament, or bursa. Pain restricts the passive and active range of motion of the shoulder joint, impairing the quality of daily life and activity. It is thought to be between 20% and 50% in the adult population in a 1-year period, and its lifetime prevalence is approximately 10%. Central sensitization develops in cases where the pain is progressive and becomes chronic over time. It has been observed that it becomes chronic in more than 40% of patients in a 1-year period. Thus, shoulder pain becomes a biopsychosocial disease over time. Physical therapy, medical, interventional methods, and surgery are applied in the treatment of shoulder pain. In physical therapy, exercises and some physical medicine modalities are applied to increase joint range of motion and reduce pain, while in medical treatment, oral analgesics, myorelaxants, and topical analgesics are used. Interventional intra-articular steroid injections and distal suprascapular nerve (SS) blockade radiofrequency applications are among the effective treatment options.
NCT07173517
Traditional sacral neuromodulation devices are not rechargeable. In recent years, new rechargeable sacral neuromodulation devices have been developed and put into the market. The aim of this study was to evaluate the cost savings of a rechargeable sacral neuromodulation device versus a non-rechargeable sacral neuromodulation device for the treatment of neurogenic lower urinary tract dysfunction.
NCT07054424
The goal of this clinical trial is to evaluate whether combining repetitive transcranial magnetic stimulation (rTMS) with machine-assisted bimanual therapy (BT) can improve upper limb function in stroke patients. The participants will be individuals aged 40-80 years who have experienced a first-time ischemic or hemorrhagic stroke. The main questions it aims to answer are: * Does the combined therapy enhance motor recovery compared to traditional rehabilitation methods? * Are changes in brain activity associated with improvements in upper limb function? Participants will be randomly assigned to different groups and will: * Receive rTMS stimulation on specific areas of the brain to modulate neural activity, * Perform machine-assisted bimanual exercises to promote motor skills, and * Undergo assessments before, immediately after, and during follow-up periods to measure functional improvements.
NCT06990295
This study evaluates the safety and effectiveness of focused ultrasound spleen neuromodulation in patients with septic shock, a life-threatening condition characterized by excessive inflammation and organ dysfunction. The primary objective is to determine whether non-invasive, focused ultrasound stimulation of the spleen can reduce circulating inflammatory cytokine levels in this patient population. Eligibility Criteria: Adults aged 18 years or older Diagnosed with septic shock and admitted to the ICU within 24 hours Expected to require intensive care for at least 72 hours Study Protocol: Participants will be randomly assigned to one of two groups: Intervention Group: Will receive standard septic shock care plus twice-daily focused ultrasound stimulation over the spleen for five days, using a portable device. Control Group: Will receive standard septic shock care alone. Blood samples will be collected at baseline, Day 3, and Day 5 to measure inflammatory cytokine levels, including TNF-α, IL-1β, IL-6, and IL-10. Additional assessments will include lymphocyte subpopulations, organ function scores, ICU length of stay, 28-day mortality, and adverse events. Outcome Measures: Primary: Change in levels of inflammatory cytokines on Day 3 and Day 5. Secondary: Changes in organ function (SOFA score), ICU length of stay, 28-day survival, and safety/tolerability of the intervention.

NCT06464445
Repetitive TMS (rTMS) is a well-established method for modulating brain activity. Through successive stimulations in the form of magnetic fields, it is possible to modify the sensitivity of neurons in the brain, also known as cortical excitability. Cortical excitability is important for the induction of brain plasticity, the ability of the brain to reorganize itself and form new connections in response to stimuli. A particular class of rTMS, intermittent theta burst TMS (iTBS), is commonly used to modulate cortical excitability and induce plasticity for therapeutic purposes, notably for treatment-resistant depression. Different iTBS stimulation parameters can be used to induce plasticity. This study will focus on two parameters, namely, the form and duration of the electromagnetic stimulation. The shape of the electromagnetic pulse refers to how the electromagnetic wave is configured over time, while the duration is simply the period during which this electromagnetic pulse remains active. These parameters are expected to influence the effectiveness of iTBS in modulating cortical activity but remain little studied. The main aim of this study will be to compare the effectiveness of different stimulation parameters in the induction of plasticity, which will then make it possible to improve the rTMS protocols used for treatment-resistant depression.
NCT06000592
Current forms of pharmacologic and non-pharmacologic treatments for hypotension and orthostatic hypotension (OH) remain inadequate during acute inpatient rehabilitation (AIR) following a traumatic spinal cord injury (SCI). A critical need exists for the identification of safe, practical, and effective treatment options that stabilize blood pressure (BP) after traumatic SCI. Recent published evidence suggests that transcutaneous Spinal Cord Stimulation (TSCS) can be used to raise seated BP, and mitigate the falls in BP during orthostatic repositioning in individuals with chronic SCI. This site-specific project will focus on the use of TSCS to stabilizing seated BP and mitigate the fall in BP during orthostatic repositioning during AIR following traumatic SCI.
NCT06251479
Based on study literature, the investigators can say that our study aims to give an explanation not only from a behavioral point of view but also with respect to what are the neuronal mechanisms underlying our ability to perceive and analyze our own and others' actions. This is essential to fully understand the complexity of our social behaviors. The knowledge of these mechanisms has a high value and relevant implications for many research fields both within and outside the neurosciences. The project aims to study the neurobehavioral correlates of verbal and non-verbal communication. Through the use of non-invasive behavioral and neurophysiological techniques, the study intends to highlight the neurobehavioral markers that allow to quantify the temporal evolution of communication dynamics in healthy subjects.
NCT06213012
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.
NCT06193278
Parkinsonian Syndromes (PDS) with predominant motor dysfunction include progressive supranuclear palsy (PSP), multiple system atrophy (MSA) and corticobasal degeneration (CBD). Current treatment options for PDS are extremely limited due to the less understanding of disease pathophysiology and lack of therapeutic targets. Combining the results of previous studies and our group's previous research, sixty qualified PDS patients would be enrolled to conduct a prospective single-center randomized sham controlled clinical trial to verify the new therapeutic options that can improve symptoms and effectively slow the progression of the disease.

The goal of this online survey is to gain further insights in the needs and burden for a European registry for neuromodulation, according to healthcare providers.
NCT02357784
Women with Dual Incontinence (DI) (both Urinary Incontinence (UI) and Fecal Incontinence (FI)) often have more bothersome symptoms, quality of life impact, and sexual dysfunction than those with just UI or FI. In many situations, DI is the result of a failure of communication between the brain and the sacral nerve, which controls the bladder, bowel, and pelvic floor. The only currently available treatment with level 1 effectiveness data for the treatment of BOTH UI and FI is called Sacral Neuromodulation (SNM). Sacral Neuromodulation is a standard of care treatment that involves surgically implanting a device in to a patient's body to target communication issues between their brain and bladder/bowel. Because the exact mechanism of action of SNM remains unclear, this study aims to better understand how SNM affects the nerves of patients with DI. Patients who are already planning on undergoing SNM device implantation will be recruited to this study. Study participants will undergo Current Perception Threshold (CPT) Testing and fill out questionnaires before SNM and 3 months after their SNM treatment. CPT Testing uses mild electrical stimulation in the urethra and rectum to measure and quantify the amount of physical stimuli required for the nerves in the pelvic floor to sense a stimulus. By learning more about nerve function in patients with DI, the investigators hope to find a way to screen patients before treatment with SNM to make sure the treatment will be effective for that individual.

The goal of this online survey is to gain further insight in the goals, expectations and definition of success for neuromodulation for pain, according to healthcare providers.
NCT04884932
High-frequency alternating currents of greater than 1 kHz applied on peripheral nerves has been used in animal studies to produce a motor nerve block. It has been evidenced that frequencies higher than 5 kHz are necessary to produce a complete peripheral nerve block in primates, whose nerve thickness is more similar to humans.
NCT03994991
Patients with high severity of post-surgical pain scores will be randomized to transcranial magnetic stimulation (TMS) vs sham TMS groups. Both group of patients will have 10 TMS sessions during 5 days. Our hypothesis is that, the reduction in the severity of pain scores will be greater among those patients who are randomized to active TMS group compared to sham TMS group. The investigators will explore how improvements in pain correlate with changes in brain network connectivity.
