Filter by: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.
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.
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.
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.
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.
Objectives: To evaluate pressure pain thresholds, fatigue scales, quality of life and sleep quality, in women with Persistent Covid (PC), pre- and post-treatment using electrotherapy and in a placebo group of PC patients. Relevance: This trial can be a tool for patients affected by CP who present pain and fatigue problems, insomnia or signs of imbalance of their Autonomic Nervous System. It aims to improve their rest and recovery for a better quality of life that allows them to recover their Activities of Daily Living. We have designed the study with a commitment to placebo group treatment after completion, if positive results are obtained. A 6-month and 1-year follow-up will be scheduled. Secondary objectives: To analyze the effects on quality of life, fatigue and sleep. To analyze the presence of cardiac variability and pre- and post-treatment cortisol values. Patients and Methods: 12 patients with CP will receive 15 sessions of electrotherapy. 12 will receive a placebo. Mechanical sensitivity pre-post, by means of an algometer, cardiac variability, cortisol levels, and other variables, will be measured by means of questionnaires. Mechanical sensitivity to pain will be measured using an algometer (Baseline 12-0300 MMT). Patients will be instructed to report when the sensation of pressure changes to pain. The pre-post electrotherapy treatment described above will be measured, the differences in mechanical sensitivity, pain threshold to pressure, the Pittsburg questionnaires, SF-36, MFIS and EQooL-5. Follow-up will be done at 6 months and at one year. The study design is a triple-blind randomized controlled clinical trial. Patients who sign the consent form will be evaluated by an internist who will perform a physical examination at the clinic of the Faculty of Nursing and Physiotherapy of the Pontifical University of Salamanca (UPSA). The sample will be randomized. 12 patients will receive treatment and 12 patients will receive a placebo. With a commitment to treat these patients in the event that positive results are obtained after the end of the study. A biphasic microcurrent will be applied with a frequency between 1.14 Hertz and 14.29 Hertz and intensities between 0.1 and 0.9 mA. Frequency: 2 times a week. A total of 15 sessions in 7.5 weeks. The session time with microcurrents will last 60 minutes. .
Tinnitus is the awareness of sound or noise in the absence of acoustic stimulation. No definite therapeutic strategy of tinnitus has been developed yet. The current theory of tinnitus is the plasticity theory of neurophysiology model. Although acupuncture has its role in tinnitus treatment, its actual role still remains to be elucidated. Acupuncture has been proposed to induce the development of neuroplasticity. The aim of this project is to undergo a comprehensive investigation to the central auditory effect and the therapeutic effects of acupuncture in tinnitus. According the results of the preliminary studies, the objective auditory measurement and subjective tinnitus perception will be analyzed in tinnitus patients before and after acupuncture.
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.
Low back pain affects people of all ages and has become the leading cause of living with disability worldwide. Patients, suffering from persistent pain after spinal surgery in the absence of any clear spinal pathology are defined of having a "failed back surgery syndrome (FBSS)" and treatment of FBSS remains a great controversy in the spinal community. Apart from conservative treatment, spinal fusion remains as therapeutic option. Furthermore, minimal invasive Neuromodulation techniques might be a promising alternative. Aim of this randomized interventional multi center study is to compare treatment success in FBSS patients with either spinal cord stimulation (SCS) or fusion surgery, 12 months after intervention according to the Oswestry Disability Index (ODI) and other scales and scores. Radiological and health economic outcome also will be analysed for thorough comparison of techniques. Additionally, the safety of the interventions needs to be compared.
