- Applications of Non-invasive Neuromodulation for the Management of Disorders Related to COVID-19(2020) BAPTISTA, Abrahao Fontes; BALTAR, Adriana; OKANO, Alexandre Hideki; MOREIRA, Alexandre; CAMPOS, Ana Carolina Pinheiro; FERNANDES, Ana Mercia; BRUNONI, Andre Russowsky; BADRAN, Bashar W.; TANAKA, Clarice; ANDRADE, Daniel Ciampi de; MACHADO, Daniel Gomes da Silva; MORYA, Edgard; TRUJILLO, Eduardo; SWAMI, Jaiti K.; CAMPRODON, Joan A.; MONTE-SILVA, Katia; SA, Katia Nunes; NUNES, Isadora; GOULARDINS, Juliana Barbosa; BIKSON, Marom; SUDBRACK-OLIVEIRA, Pedro; CARVALHO, Priscila de; DUARTE-MOREIRA, Rafael Jardim; PAGANO, Rosana Lima; SHINJO, Samuel Katsuyuki; ZANA, YossiBackground: Novel coronavirus disease (COVID-19) morbidity is not restricted to the respiratory system, but also affects the nervous system. Non-invasive neuromodulation may be useful in the treatment of the disorders associated with COVID-19. Objective: To describe the rationale and empirical basis of the use of non-invasive neuromodulation in the management of patients with COVID-10 and related disorders. Methods: We summarize COVID-19 pathophysiology with emphasis of direct neuroinvasiveness, neuroimmune response and inflammation, autonomic balance and neurological, musculoskeletal and neuropsychiatric sequela. This supports the development of a framework for advancing applications of non-invasive neuromodulation in the management COVID-19 and related disorders. Results: Non-invasive neuromodulation may manage disorders associated with COVID-19 through four pathways: (1) Direct infection mitigation through the stimulation of regions involved in the regulation of systemic anti-inflammatory responses and/or autonomic responses and prevention of neuroinflammation and recovery of respiration; (2) Amelioration of COVID-19 symptoms of musculoskeletal pain and systemic fatigue; (3) Augmenting cognitive and physical rehabilitation following critical illness; and (4) Treating outbreak-related mental distress including neurological and psychiatric disorders exacerbated by surrounding psychosocial stressors related to COVID-19. The selection of the appropriate techniques will depend on the identified target treatment pathway. Conclusion: COVID-19 infection results in a myriad of acute and chronic symptoms, both directly associated with respiratory distress (e.g., rehabilitation) or of yet-to-be-determined etiology (e.g., fatigue). Non-invasive neuromodulation is a toolbox of techniques that based on targeted pathways and empirical evidence (largely in non-COVID-19 patients) can be investigated in the management of patients with COVID-19.
- Electroacupuncture modulates cortical excitability in a manner dependent on the parameters used(2022) BRITO, Francisco Xavier de; LUZ-SANTOS, Cleber; CAMATTI, Janine Ribeiro; FONSECA, Rodrigo Jorge de Souza da; SUZARTH, Giovana; MORAES, Laise Monteiro Campos; SILVA, Marcelo Lourenco da; SILVA, Josie Resende Torres da; VERCELINO, Rafael; SA, Katia Nunes; ZANA, Yossi; BAPTISTA, Abrahao FontesIntroduction: There is evidence that electroacupuncture (EA) acts through the modulation of brain activity, but little is known about its influence on corticospinal excitability of the primary motor cortex (M1). Objective: To investigate the influence of EA parameters on the excitability of M1 in healthy individuals. Methods: A parallel, double blind, randomized controlled trial in healthy subjects, evaluating the influence of an EA intervention on M1 excitability. Participants had a needle inserted at LI4 in the dominant hand and received electrical stimulation of different frequencies (10 or 100 Hz) and amplitude (sensory or motor threshold) for 20 min. In the control group, only a brief (30 s) electrical stimulation was applied. Single and paired pulse transcranial magnetic stimulation coupled with electromyography was applied before and immediately after the EA intervention. Resting motor threshold, motor evoked potential, short intracortical inhibition and intracortical facilitation were measured. Results: EA increased corticospinal excitability of M1 compared to the control group only when administered with a frequency of 100 Hz at the sensory threshold (p < 0.05). There were no significant changes in the other measures. Conclusion: The results suggest that EA with an intensity level at the sensorial threshold and 100 Hz frequency increases the corticospinal excitability of M1. This effect may be associated with a decrease in the activity of inhibitory intracortical mechanisms.
- Closed-loop neurostimulation for affective symptoms and disorders: An overview(2021) MORENO, Javier Guerrero; JR, Claudinei Eduardo Biazoli; BAPTISTA, Abrahao Fontes; TRAMBAIOLLI, Lucas RemoaldoAffective and anxiety disorders are the most prevalent and incident psychiatric disorders worldwide. Therapeutic approaches to these disorders using non-invasive brain stimulation (NIBS) and analogous techniques have been extensively investigated. In this paper, we discuss the combination of NIBS and neurofeedback in closed-loop setups and its application for affective symptoms and disorders. For this, we first provide a rationale for this combination by presenting some of the main original findings of NIBS, with a primary focus on transcranial magnetic stimulation (TMS), and neurofeedback, including protocols based on electroencephalography (EEG) and functional magnetic resonance imaging (fMRI). Then, we provide a scope review of studies combining realtime neurofeedback with NIBS protocols in the so-called closed-loop brain state-dependent neuromodulation (BSDS). Finally, we discuss the concomitant use of TMS and real-time functional near-infrared spectroscopy (fNIRS) as a possible solution to the current limitations of BSDS-based protocols for affective and anxiety disorders.
- Latin American and Caribbean consensus on noninvasive central nervous system neuromodulation for chronic pain management (LAC(2)-NIN-CP)(2019) BAPTISTA, Abrahao Fontes; FERNANDES, Ana Mercia B. L.; SA, Katia Nunes; OKANO, Alexandre Hideki; BRUNONI, Andre Russowsky; LARA-SOLARES, Argelia; ISKANDAR, Aziza Jreige; GUERRERO, Carlos; AMESCUA-GARCIA, Cesar; KRAYCHETE, Durval Campos; CAPARELLI-DAQUER, Egas; ATENCIO, Elias; PIEDIMONTE, Fabian; COLIMON, Frantz; HAZIME, Fuad Ahmed; GARCIA, Joao Batista S.; HERNANDEZ-CASTRO, John Jairo; CANTISANI, Jose Alberto Flores; MONTE-SILVA, Katia Karina do; CORREIA, Luis Claudio Lemos; GALLEGOS, Manuel Sempertegui; MARCOLIN, Marco Antonio; RICCO, Maria Antonieta; COOK, Maria Berenguel; BONILLA, Patricia; SCHESTATSKY, Pedro; GALHARDONI, Ricardo; SILVA, Valquiria; BARRERA, William Delgado; CAUMO, Wolnei; BOUHASSIRA, Didier; CHIPCHASE, Lucy S.; LEFAUCHEUR, Jean-Pascal; TEIXEIRA, Manoel Jacobsen; ANDRADE, Daniel Ciampi deIntroduction: Chronic pain (CP) is highly prevalent and generally undertreated health condition. Noninvasive brain stimulation may contribute to decrease pain intensity and influence other aspects related to CP. Objective: To provide consensus-based recommendations for the use of noninvasive brain stimulation in clinical practice. Methods: Systematic review of the literature searching for randomized clinical trials followed by consensus panel. Recommendations also involved a cost-estimation study. Results: The systematic review wielded 24 transcranial direct current stimulation (tDCS) and 22 repetitive transcranial magnetic stimulation (rTMS) studies. The following recommendations were provided: (1) Level A for anodal tDCS over the primary motor cortex (M1) in fibromyalgia, and level B for peripheral neuropathic pain, abdominal pain, and migraine; bifrontal (F3/F4) tDCS and M1 high-definition (HD)-tDCS for fibromyalgia; Oz/Cz tDCS for migraine and for secondary benefits such as improvement in quality of life, decrease in anxiety, and increase in pressure pain threshold; (2) level A recommendation for high-frequency (HF) rTMS over M1 for fibromyalgia and neuropathic pain, and level B for myofascial or musculoskeletal pain, complex regional pain syndrome, and migraine; (3) level A recommendation against the use of anodal M1 tDCS for low back pain; and (4) level B recommendation against the use of HF rTMS over the left dorsolateral prefrontal cortex in the control of pain. Conclusion: Transcranial DCS and rTMS are recommended techniques to be used in the control of CP conditions, with low to moderate analgesic effects, and no severe adverse events. These recommendations are based on a systematic review of the literature and a consensus made by experts in the field. Readers should use it as part of the resources available to decision-making.
- Beyond the target area: an integrative view of tDCS-induced motor cortex modulation in patients and athletes(2019) MORYA, Edgard; MONTE-SILVA, Katia; BIKSON, Marom; ESMAEILPOUR, Zeinab; BIAZOLI JR., Claudinei Eduardo; FONSECA, Andre; BOCCI, Tommaso; FARZAN, Faranak; CHATTERJEE, Raaj; HAUSDORFF, Jeffrey M.; MACHADO, Daniel Gomes da Silva; BRUNONI, Andre Russowsky; MEZGER, Eva; MOSCALESKI, Luciane Aparecida; PEGADO, Rodrigo; SATO, Joao Ricardo; CAETANO, Marcelo Salvador; SA, Katia Nunes; TANAKA, Clarice; LI, Li Min; BAPTISTA, Abrahao Fontes; OKANO, Alexandre HidekiTranscranial Direct Current Stimulation (tDCS) is a non-invasive technique used to modulate neural tissue. Neuromodulation apparently improves cognitive functions in several neurologic diseases treatment and sports performance. In this study, we present a comprehensive, integrative review of tDCS for motor rehabilitation and motor learning in healthy individuals, athletes and multiple neurologic and neuropsychiatric conditions. We also report on neuromodulation mechanisms, main applications, current knowledge including areas such as language, embodied cognition, functional and social aspects, and future directions. We present the use and perspectives of new developments in tDCS technology, namely high-definition tDCS (HD-tDCS) which promises to overcome one of the main tDCS limitation (i.e., low focality) and its application for neurological disease, pain relief, and motor learning/rehabilitation. Finally, we provided information regarding the Transcutaneous Spinal Direct Current Stimulation (tsDCS) in clinical applications, Cerebellar tDCS (ctDCS) and its influence on motor learning, and TMS combined with electroencephalography (EEG) as a tool to evaluate tDCS effects on brain function.
