    Non-invasive insular stimulation for peripheral neuropathic pain: Influence of target or symptom?
    (2022) CUNHA, Pedro Henrique Martins da; Liu Dongyang; FERNANDES, Ana Mercia; THIBES, Raissa Benocci; SATO, Joao; TANAKA, Harki; DALE, Camila; LAPA, Jorge Dornellys da Silva; MORAIS, Adriano Donizeth Silva de; SOARES, Felipe Henriques Carvalho; SILVA, Valquiria Aparecida da; GRAVEN-NIELSEN, Thomas; TEIXEIRA, Manoel Jacobsen; ANDRADE, Daniel Ciampi de
    Objectives: The posterior-superior insula (PSI) has been shown to be a safe and potentially effective target for neuromodulation in peripheral neuropathic pain (PNP) in humans and animal models. However, it remains unknown whether there is a measurable responder profile to PSI stimulation. Two factors were hypothesized to influence the response of repetitive transcranial magnetic stimulation (rTMS) of the PSI: differences in rTMS target (discrete subregions of the PSI) or PNP phenotype. Methods: This is a secondary analysis from a randomized, double-blind, sham-controlled, crossover trial assessing PSI-rTMS in PNP (N = 31, 5 days rTMS) (10.1016/j.neucli.2021.06.003). Active PSI-rTMS true responders (>50% pain reduction from baseline after active but not after sham series of treatment) were compared with not true responders, to determine whether they differed with respect to 1) rTMS neuro-navigational target coordinates, and/or 2) specific neuropathic pain symptom inventory (NPSI) clusters (pinpointed pain, evoked pain, and deep pain) at baseline. Results: Mean rTMS target coordinates did not differ between true (n = 45.1%) and not true responders (p = 0.436 for X, p = 0.120 for Y, and p = 0.116 for Z). The Euclidian distance between true and not true responders was 4.04 mm. When comparing differences in responders between NPSI clusters, no participant within the evoked pain cluster was a true responder (p = 0.024). Conclusion: Response to PSI-rTMS may depend on pain cluster subtype rather than on differences in targeting within the PSI.

    Sifting the wheat from the chaff? Evidence for the existence of an asymmetric fibromyalgia phenotype
    (2020) KAZIYAMA, Helena H.; BARBOUR, Julio; GALHARDONI, Ricardo; SILVA, Valquiria Aparecida da; SIQUEIRA, Silvia R. D. Tesseroli de; LISTIK, Clarice; SANTOS, Gabriel Jose dos; YENG, Lin T.; MARCOLIN, Marco Antonio; RAICHER, Irina; TEIXEIRA, Manoel J.; ANDRADE, Daniel Ciampi de
    Background The different phenotypic presentations of fibromyalgia (FM) have been infrequently studied and may have diagnostic and therapeutic implications. The aim of this study was to explore differences between FM patients with classical symmetric (s-FM) presentation and FM patients with marked asymmetric (a-FM) pain. Methods We performed two consecutive cross-sectional studies on FM patients and matched healthy volunteers (HV). FM patients were divided into a-FM (and s-FM groups according to their score of pain intensity on each body side; patients with a difference of >= 40 mm in VAS between left and right sides were classified as a-FM, otherwise classified as s-FM. Participants (FM = 32; HV = 31) were assessed for clinical, cortical excitability (CE), quantitative sensory testing (QST; study 1), and intraepidermal nerve fibre density (IENFD) determinations (study 2). Results While pain intensity did not significantly differ between s-FM and a-FM patients, pain interference in daily activities was significantly higher in the a-FM as compared to the s-FM group (54.7 +/- 8.9 and 37.6 +/- 13.5;p < .0001). PPT was significantly lower in the more painful side of a-FM as compared to the HV (27.7 +/- 7.9 and 49.9 +/- 13.0;p < .0001), while PPT in the less painful side of a-FM was significantly higher than PPT values in the s-FM (35.8 +/- 8.3 and 27.7 +/- 5.5;p = .031). S-FM and a-FM had significantly abnormal intracortical inhibition values on CE measurements compared to HV. There were no significant differences in IENFD between groups. Conclusions Within the current FM criteria, there exist different phenotypes with clinical, psychophysics, and neurophysiological findings that are not related to peripheral IENFD abnormalities. Significance Current fibromyalgia criteria may contain different phenotypes of fibromyalgia based on the lateralization of pain.

    Corticomotor excitability is altered in central neuropathic pain compared with non-neuropathic pain or pain-free patients
    (2023) BARBOSA, Luciana Mendonca; VALERIO, Fernanda; SILVA, Valquiria Aparecida da; RODRIGUES, Antonia Lilian de Lima; GALHARDONI, Ricardo; YENG, Lin Tchia; JUNIR, Jefferson Rosi; CONFORTO, Adriana Bastos; LUCATO, Leandro Tavares; TEIXEIRA, Manoel Jacobsen; ANDRADE, Daniel Ciampi de
    Objectives: Central neuropathic pain (CNP) is associated with altered corticomotor excitability (CE), which can potentially provide insights into its mechanisms. The objective of this study is to describe the CE changes that are specifically related to CNP.Methods: We evaluated CNP associated with brain injury after stroke or spinal cord injury (SCI) due to neuromyelitis optica through a battery of CE measurements and comprehensive pain, neurological, functional, and quality of life assessments. CNP was compared to two groups of patients with the same disease: i. with non-neuropathic pain and ii. without chronic pain, matched by sex and lesion location.Results: We included 163 patients (stroke=93; SCI=70: 74 had CNP, 43 had non-neuropathic pain, and 46 were pain-free). Stroke patients with CNP had lower motor evoked potential (MEP) in both affected and unaffected hemispheres compared to non-neuropathic pain and no-pain patients. Patients with CNP had lower amplitudes of MEPs (366 mu V +/- 464 mu V) than non-neuro-pathic (478 +/- 489) and no-pain (765 mu V +/- 880 mu V) patients, p < 0.001. Short-interval intracorti-cal inhibition (SICI) was defective (less inhibited) in patients with CNP (2.6 +/- 11.6) compared to no-pain (0.80.7), p = 0.021. MEPs negatively correlated with mechanical and cold-induced allo-dynia. Furthermore, classifying patients' results according to normative data revealed that at least 75% of patients had abnormalities in some CE parameters and confirmed MEP findings based on group analyses.Discussion: CNP is associated with decreased MEPs and SICI compared to non-neuropathic pain and no-pain patients. Corticomotor excitability changes may be helpful as neurophysiological markers of the development and persistence of pain after CNS injury, as they are likely to pro-vide insights into global CE plasticity changes occurring after CNS lesions associated with CNP.(c) 2023 The Author(s).

    Balloon compression vs radiofrequency for primary trigeminal neuralgia: a randomized, controlled trial
    (2021) STERMAN-NETO, Hugo; FUKUDA, Cristiane Yoko; DUARTE, Kleber Paiva; SILVA, Valquiria Aparecida da; RODRIGUES, Antonia Lilian de Lima; GALHARDONI, Ricardo; SIQUEIRA, Silvia R. D. T. de; SIQUEIRA, Jose Tadeu Tesseroli de; TEIXEIRA, Manoel Jacobsen; ANDRADE, Daniel Ciampi de
    Surgical procedures are necessary in up to 50% of trigeminal neuralgia patients. Although radiofrequency (RF) is more widely used, it is associated with high intraprocedural costs and long technical learning time. Other simpler procedures such as balloon compression (BC) require a lower training period and have significant lower costs. We evaluated the effects of BC and RF in pain control in primary trigeminal neuralgia in a randomized, double-blinded, head-to-head trial. Individuals were randomly allocated in 1 of 2 groups: BC and RF. Throughout pain, psychological and quality of life measurements were performed at baseline and after surgery. The main outcome was the worst pain in the last 24 hours (0-10) at 6 months postoperatively. After the inclusion of half of the estimated sample, a preplanned interim analysis was performed when 33 patients (62.1 = 9.4 y.) completed the study. Pain intensity (confidence interval [Cl] 95% 0.6 to 3.8, and -0.6 to 2.2, for BC and RF) did not significantly differ. Complications, interference of pain in daily life (01 95% -0.1 to 2.3 and -0.4 to 2.3, for BC and RF), neuropathic pain symptoms (01 95% 1.7 to 3.6 and 3.0 to 5.7, for BC and RF), mood (0195% 4.8 to 11.5 and 5.5 to 15.1, BC and RF, respectively), medication use, and quality of life (0195% 80.4 to 93.1 and 83.9 to 94.2, for BC and RF) were also not different. Radiofrequency presented more paresthetic symptoms than BC at 30 days after intervention. Based on these results, the study was halted due to futility because BC was not superior to RF.

    Posterior-superior insular deep transcranial magnetic stimulation alleviates peripheral neuropathic pain - A pilot double-blind, randomized cross-over study
    (2021) DONGYANG, Liu; FERNANDES, Ana Mercia; CUNHA, Pedro Henrique Martins da; TIBES, Raissa; SATO, Joao; LISTIK, Clarice; DALE, Camila; KUBOTA, Gabriel Taricani; GALHARDONI, Ricardo; TEIXEIRA, Manoel Jacobsen; SILVA, Valquiria Aparecida da; ROSI, Jefferson; ANDRADE, Daniel Ciampi de
    Objectives. - Peripheral neuropathic pain (pNeP) is prevalent, and current treatments, including drugs and motor cortex repetitive transcranial magnetic stimulation (rTMS) leave a substantial proportion of patients with suboptimal pain relief. Methods. - We explored the intensity and short-term duration of the analgesic effects produced in pNeP patients by 5 days of neuronavigated deep rTMS targeting the posterior superior insula (PSI) with a double-cone coil in a sham-controlled randomized cross-over trial. Results. - Thirty-one pNeP patients received induction series of five active or sham consecutive sessions of daily deep-rTMS to the PSI in a randomized sequence, with a washout period of at least 21 days between series. The primary outcome [number of responders (>50% pain intensity reduction from baseline in a numerical rating scale ranging from 0 to 10)] was significantly higher after real (58.1%) compared to sham (19.4%) stimulation (p = 0.002). The number needed to treat was 2.6, and the effect size was 0.97 [95% CI (0.6; 1.3)]. One week after the 5th stimulation day, pain scores were no longer different between groups, and no difference in neuropathic pain characteristics and interference with daily living were present. No major side effects occurred, and milder adverse events (i.e., short-lived headaches after stimulation) were reported in both groups. Blinding was effective, and analgesic effects were not affected by sequence of the stimulation series (active-first or sham-first), age, sex or pain duration of participants. Discussion. - PSI deep-rTMS was safe in refractory pNeP and was able to provide significant pain intensity reduction after a five-day induction series of treatments. Post-hoc assessment of neuronavigation targeting confirmed deep-rTMS was delivered within the boundaries of the PSI in all participants. Conclusion. - PSI deep-rTMS provided significant pain relief during 5-day induction sessions compared to sham stimulation.

    Effects of cerebellar neuromodulation in movement disorders: A systematic review
    (2018) FRANCA, Carina; ANDRADE, Daniel Ciampi de; TEIXEIRA, Manoel Jacobsen; GALHARDONI, Ricardo; SILVA, Valquiria; BARBOSA, Egberto Reis; CURY, Rubens Gisbert
    Background: The cerebellum is involved in the pathophysiology of many movement disorders and its importance in the field of neuromodulation is growing. Objectives: To review the current evidence for cerebellar modulation in movement disorders and its safety profile. Methods: Eligible studies were identified after a systematic literature review of the effects of cerebellar modulation in cerebellar ataxia, Parkinson's disease (PD), essential tremor (ET), dystonia and progressive supranuclear palsy (PSP). Neuromodulation techniques included transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS) and deep brain stimulation (DBS). The changes in motor scores and the incidence of adverse events after the stimulation were reviewed. Results: Thirty-four studies were included in the systematic review, comprising 431 patients. The evaluation after stimulation ranged from immediately after to 12 months after. Neuromodulation techniques improved cerebellar ataxia due to vascular or degenerative etiologies (TMS, tDCS and DBS), dyskinesias in PD patients (TMS), gross upper limb movement in PD patients (tDCS), tremor in ET (TMS and tDCS), cervical dystonia (TMS and tDCS) and dysarthria in PSP patients (TMS). All the neuromodulation techniques were safe, since only three studies reported the existence of side effects (slight headache after TMS, local skin erythema after tDCS and infectious complication after DBS). Eleven studies did not mention if adverse events occurred. Conclusions: Cerebellar modulation can improve specific symptoms in some movement disorders and is a safe and well-tolerated procedure. Further studies are needed to lay the groundwork for new researches in this promising target.

    Motor corticospinal excitability abnormalities differ between distinct chronic low back pain syndromes
    (2023) SILVA, Marcelo Luiz da; FERNANDES, Ana Mercia; SILVA, Valquiria A.; GALHARDONI, Ricardo; FELAU, Valter; ARAUJO, Joaci O. de; JR, Jefferson Rosi; BROCK, Roger S.; KUBOTA, Gabriel T.; TEIXEIRA, Manoel J.; YENG, Lin T.; ANDRADE, Daniel Ciampi de
    Objectives: It is not known whether cortical plastic changes reported in low-back pain (LBP) are present in all etiologies of LBP. Here we report on the assessment of patients with three LBP con-ditions: non-specific-LBP (ns-LBP), failed back surgery syndrome (FBSS), and sciatica (Sc).Methods: Patients underwent a standardized assessment of clinical pain, conditioned pain mod-ulation (CPM), and measures of motor evoked potential (MEPs)-based motor corticospinal excit-ability (CE) by transcranial magnetic stimulation, including short interval intracortical inhibition (SICI), and intracortical facilitation (ICF). Comparisons were also made with normative data from sex-and age-matched healthy volunteers.Results: 60 patients (42 women, 55.1 +/- 9.1 years old) with LBP were included (20 in each group). Pain intensity was higher in patients with neuropathic pain [FBSS (6.8 +/- 1.3), and Sc (6.4 +/- 1.4)] than in those with ns-LBP (4.7 +/- 1.0, P<0.001). The same was shown for pain interference (5.9 +/- 2.0, 5.9 +/- 1.8, 3.2 +/- 1.9, P<0.001), disability (16.4 +/- 3.3, 16.3 +/- 4.3, 10.4 +/- 4.3, P<0.001), and catastrophism (31.1 +/- 12.3, 33.0 +/- 10.4, 17.4 +/- 10.7, P<0.001) scores for FBSS, Sc, and ns-LBP groups, respectively. Patients with neuropathic pain (FBSS, Sc) had lower CPM (-14.8 +/- 1.9,-14.1 +/- 16.7, respectively) compared to ns-LBP (-25.4 +/- 16.6; P<0.02). 80.0% of the FBSS group had defective ICF compared to the other two groups (52.5% for ns-LBP, P=0.025 and 52.5% for Sc, P=0.046). MEPs (140%-rest motor threshold) were low in 50.0% of patients in the FBSS group com-pared to 20.0% of ns-LBP (P=0.018) and 15.0% of Sc (P=0.001) groups. Higher MEPs were corre-lated with mood scores (r=0.489), and with lower neuropathic pain symptom scores(r=-0.415) in FBSS.Conclusions: Different types of LBP were associated with different clinical, CPM and CE profiles, which were not uniquely related to the presence of neuropathic pain. These results highlight the need to further characterize patients with LBP in psychophysics and cortical neurophysiology studies.(c) 2023 The Author(s).

    Pain paths among post-COVID-19 condition subjects: A prospective cross-sectional study with in-person evaluation
    (2023) KUBOTA, Gabriel T.; SOARES, Felipe H. C.; FONSECA, Alessandra S. da; ROSA, Talita dos Santos; SILVA, Valquiria A. da; GOUVEIA, Gisele R.; FARIA, Viviane G.; CUNHA, Pedro H. M. da; BRUNONI, Andre R.; TEIXEIRA, Manoel J.; ANDRADE, Daniel C. de
    BackgroundNew-onset chronic pain has been acknowledged as part of the post-COVID-19 condition. However, available fine-grained data about its clinical phenotype, trajectories and main associated characteristics remain scarce. We described the distinct temporal evolutions of post-COVID-19 pain and their epidemiological and phenotypical features. MethodsA prospective cross-sectional study enrolled post-COVID-19 condition patients (i.e. who had persisting COVID-19-related symptoms over 30 days since their first positive laboratory test), whose COVID-19 diagnosis had been supported by RT-PCR of oral/nasopharyngeal swab or serology. They underwent in-person evaluations with a structured interview, pain and quality-of-life-related questionnaires and thorough physical examination. Chronic pain (CP) and probable neuropathic pain (NP) were defined according to IASP criteria. ResultsThe present study included 226 individuals, 177 (78.3%) of whom presented over 3 months since their first COVID-19 symptom. New-onset pain occurred in 170 (75.2%) participants and was chronic in 116 (68.2%). A chronic course was associated with COVID-19-related hospitalization, new-onset fatigue, lower cognitive performance, motor and thermal sensory deficits, mood and sleep impairments and overall lower quality-of-life levels. Probable NP occurred in only 7.6% new-onset pain patients, and was associated with pain chronification, new-onset fatigue, motor and thermal sensory deficits, mechanical allodynia and lower rates of SARS-CoV-2 vaccination. Previous CP was reported by 86 (38.1%) individuals and had aggravated after the infection in 66 (76.7%) of them, which was associated with orthostatic hypotension. ConclusionsPost-COVID pain phenomena follow different paths, which are associated with specific clinical and epidemiological features, and possibly distinct underlying mechanisms, prognostic and therapeutic implications. SignificanceCOVID-19-related pain usually follows a chronic course and is non-neuropathic. Its possible courses and phenotypes are associated with distinct clinical and epidemiological features. This suggests differing underlying mechanisms, which may have significant prognostic and therapeutic implications.

    Dissecting neuropathic from poststroke pain: the white matter within
    (2022) LEMOS, Marcelo Delboni; FAILLENOT, Isabelle; LUCATO, Leandro Tavares; TEIXEIRA, Manoel Jacobsen; BARBOSA, Luciana Mendonca; ALHO, Eduardo Joaquim Lopes; CONFORTO, Adriana Bastos; RODRIGUES, Antonia Lilian de Lima; GALHARDONI, Ricardo; SILVA, Valquiria Aparecida da; LISTIK, Clarice; ROSI, Jefferson; PEYRON, Roland; GARCIA-LARREA, Luis; ANDRADE, Daniel Ciampi de
    Poststroke pain (PSP) is a heterogeneous term encompassing both central neuropathic (ie, central poststroke pain [CPSP]) and nonneuropathic poststroke pain (CNNP) syndromes. Central poststroke pain is classically related to damage in the lateral brainstem, posterior thalamus, and parietoinsular areas, whereas the role of white matter connecting these structures is frequently ignored. In addition, the relationship between stroke topography and CNNP is not completely understood. In this study, we address these issues comparing stroke location in a CPSP group of 35 patients with 2 control groups: 27 patients with CNNP and 27 patients with stroke without pain. Brain MRI images were analyzed by 2 complementary approaches: an exploratory analysis using voxel-wise lesion symptom mapping, to detect significant voxels damaged in CPSP across the whole brain, and a hypothesis-driven, region of interest-based analysis, to replicate previously reported sites involved in CPSP. Odds ratio maps were also calculated to demonstrate the risk for CPSP in each damaged voxel. Our exploratory analysis showed that, besides known thalamic and parietoinsular areas, significant voxels carrying a high risk for CPSP were located in the white matter encompassing thalamoinsular connections (one-tailed threshold Z > 3.96, corrected P value <0.05, odds ratio = 39.7). These results show that the interruption of thalamocortical white matter connections is an important component of CPSP, which is in contrast with findings from nonneuropathic PSP and from strokes without pain. These data can aid in the selection of patients at risk to develop CPSP who could be candidates to pre-emptive or therapeutic interventions.
