Efeitos da estimulação transcraniana por corrente contínua (ETCC) na voz e fala na doença de Parkinson: relato de caso / Effects of transcranial direct current stimulation (tDCS) on voice and speech in Parkinson's disease: a case report

RESUMO Este estudo descreve os resultados de duas intervenções diferentes para a disartria na doença de Parkinson (DP). Trata-se de dois pacientes do sexo masculino com DP e disartria hipocinética que foram submetidos à avaliação fonoaudiológica. O primeiro (S1) recebeu dez sessões de 20 minutos de estimulação transcraniana por corrente contínua (ETCC), enquanto o segundo (S2) recebeu dez sessões de 20 minutos de ETCC e terapia fonoaudiológica. Os pacientes foram reavaliados imediatamente após a intervenção e novamente após 30 dias. A melhora no tempo de fonação, movimento velar e outras medidas de disartria foram mais significativas no S1. De acordo com os parâmetros da análise acústica de fonte glótica, a melhora nas medidas de frequência e Jitter, Shimmer e ruído foi maior no S2 tanto na avaliação pós-intervenção imediata quanto na avaliação 30 dias pós-intervenção, seguida por S1 na avaliação pós-intervenção imediata. S1 apresentou melhores resultados na avaliação perceptivo-auditiva de fala e voz, enquanto S2 obteve melhores escores na análise acústica. Esses achados sugerem que a terapia fonoaudiológica convencional associada à ETCC tem um impacto mais significativo na fala e voz do que a ETCC isolada, demonstrando o potencial da ETCC como tratamento complementar para pacientes com DP.

ABSTRACT This study describes the results of two different interventions for dysarthria in Parkinson's disease (PD). It concerns two male patients with PD and hypokinetic dysarthria who underwent speech and voice assessment. The first (S1) received ten 20-minute sessions of transcranial direct current stimulation (tDCS), while the second (S2) received ten 20-minute sessions of tDCS as well as speech therapy. The patients were re-evaluated immediately after the intervention and again after 30 days. Improvements in phonation time, velar movement, and other measures of dysarthria were more significant in S1. According to the acoustic analysis source parameters, improvements in the frequency measurements and Jitter, Shimmer, and noise measurements were greater in S2 in both the immediate post-intervention and 30-day postintervention assessments, followed by S1 in the immediate post-intervention assessment. S1 showed better results in the auditory-perceptual evaluation of speech and voice, whereas S2 obtained better scores in acoustic analysis. These findings suggest that conventional speech therapy combined with tDCS has a more significant impact on speech and voice than tDCS alone, demonstrating the potential of tDCS as an adjuvant treatment for patients with PD.

Effectiveness of music-based interventions for cognitive rehabilitation in Parkinson's disease: a systematic review of randomized controlled clinical trials

Abstract Background Music-based interventions are promising for cognitive rehabilitation in Parkinson's disease; however, systematic reviews covering the topic are scarce. Objective To analyze the effectiveness of music-based interventions for cognitive rehabilitation in PD. Method Systematic review study based on PRISMA criteria. The descriptors Parkinson's disease, Parkinson's disease, idiopathic Parkinson's disease, music-based interventions, music therapy, music training, auditory stimulation, music, rhythm, rhythmic, cognition, and cognitive were used. Five databases were searched PubMed/MEDLINE, PsycInfo, Scopus, Web of Science, and Cochrane in May 2022. Only randomized controlled trials with no limit on publication date or language were included. Risk of bias was assessed following Cochrane Collaboration criteria for development of systematic intervention reviews. Results Nine hundred nineteen articles were found by the descriptors; 266 were excluded for being repeated; 650 for not meeting the inclusion criteria. The remaining three articles were included and analyzed. The interventions consisted of practices with emphasis on rhythm and were conducted in groups. Risks of important biases were observed, such as lack of blinding in the allocation of participants and in the assessment of outcomes, as well as incomplete data for some outcomes. Conclusion Overall, the results showed no evidence of efficacy of music-based interventions for cognitive outcomes in PD.

Current applications for magnetic resonance-guided focused ultrasound in the treatment of Parkinson's disease / 中华医学杂志(英文版)

Magnetic resonance-guided focused ultrasound (MRgFUS) is a novel and minimally invasive technology. Since the US Food and Drug Administration approved unilateral ventral intermediate nucleus-MRgFUS for medication-refractory essential tremor in 2016, studies on new indications, such as Parkinson's disease (PD), psychiatric diseases, and brain tumors, have been on the rise, and MRgFUS has become a promising method to treat such neurological diseases. Currently, as the second most common degenerative disease, PD is a research hotspot in the field of MRgFUS. The actions of MRgFUS on the brain range from thermoablation, blood-brain barrier (BBB) opening, to neuromodulation. Intensity is a key determinant of ultrasound actions. Generally, high intensity can be used to precisely thermoablate brain targets, whereas low intensity can be used as molecular therapies to modulate neuronal activity and open the BBB in conjunction with injected microbubbles. Here, we aimed to summarize advances in the application of MRgFUS for the treatment of PD, with a focus on thermal ablation, BBB opening, and neuromodulation, in the hope of informing clinicians of current applications.

Jiao's scalp acupuncture combined with virtual reality rehabilitation training for motor dysfunction in patients with Parkinson's disease: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between Jiao's scalp acupuncture combined with virtual reality (VR) rehabilitation training and VR rehabilitation training alone for motor dysfunction in patients with Parkinson's disease (PD).@*METHODS@#A total of 52 patients with PD were randomly divided into an observation group and a control group, 26 cases in each group. The patients in both groups were treated with routine basic treatment, and the patients in the control group were treated with VR rehabilitation training. The patients in the observation group were treated with Jiao's scalp acupuncture on the basis of the control group. The scalp points included the movement area, balance area and dance tremor control area. Both groups were treated once a day, 5 times a week for a total of 8 weeks. Before treatment and 4 and 8 weeks into treatment, the gait parameters (step distance, step width, step speed and step frequency), timed "up and go" test (TUGT) time and unified Parkinson's disease rating scale part Ⅲ (UPDRS-Ⅲ) score were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Four weeks into treatment, except for the step width in the control group, the gait parameters of the two groups were improved, the TUGT time was shortened, and the UPDRS-Ⅲ scores were reduced (P<0.01, P<0.05); the step distance in the observation group was better than that in the control group, and the UPDRS-Ⅲ score in the observation group was lower than that in the control group (P<0.05). Eight weeks into treatment, the gait parameters of the two groups were improved, the TUGT time was shortened, and the UPDRS-Ⅲ scores were reduced (P<0.01); the step distance and step speed in the observation group were better than those in the control group, the TUGT time in the observation group was shorter than that in the control group, and the UPDRS-Ⅲ score in the observation group was lower than that in the control group (P<0.05, P<0.01). The total effective rate was 92.3% (24/26) in the observation group, which was higher than 69.2% (18/26) in the control group (P<0.05).@*CONCLUSION@#Jiao's scalp acupuncture combined with VR rehabilitation training could improve the gait parameters, walking ability and motor function in patients with PD. The clinical effect is better than VR rehabilitation training alone.

Effect of panlong needling at Jiaji (EX-B 2) on motor dysfunction in patients with Parkinson's disease of liver and kidney deficiency: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the curative effect of panlong needling at Jiaji (EX-B 2) combined with western medication and western medication alone on motor dysfunction in patients with Parkinson's disease (PD) of liver and kidney deficiency.@*METHODS@#A total of 98 patients with PD were randomly divided into an acupuncture and medication group (49 cases, 1 case dropped off) and a western medication group (49 cases,1 case was removed). The patients in the western medication group were given oral of levodopa and benserazide hydrochloride tablets, 125 mg each time, three times a day in the 1st week, and the dose was increased according to the needs of the patients' condition from the 2nd week until 250 mg each time, three times a day, for 16 consecutive weeks. On the basis of the same western medication treatment as the western medication group, panlong needling was applied at Jiaji (EX-B 2) from C2 to L5 in the acupuncture and medication group, once a day, 20 times as a course of treatment, for 4 consecutive courses. The scores of unified Parkinson's disease rating scale (UPDRS-Ⅲ, UPDRS-Ⅳ), TCM symptoms score, and 39-item Parkinson's disease questionnaire (PDQ-39) score were evaluated before treatment, after treatment and during follow-up of 1 month after treatment, respectively. The safety of the two groups was compared.@*RESULTS@#After treatment and during follow-up, except the PDQ-39 score of the western medication group, the scores of UPDRS-Ⅲ, UPDRS-Ⅳ, TCM syndrome and PDQ-39 were lower than those before treatment in the two groups (P<0.05), and the scores of above indexes in the acupuncture and medication group were lower than those of the western medication group (P<0.05). The total incidence of adverse reactions in the acupuncture and medication group was 10.4% (5/48), which was lower than 29.2% (14/48) in the western medication group (P<0.05).@*CONCLUSION@#Panlong needling at Jiaji (EX-B 2) combined with western medication could significantly improve the motor dysfunction and clinical symptoms, improve the quality of life and has high safety, and the efficacy is superior to western medication alone.

Exercise may improve balance on parkinson patients / El ejercicio puede mejorar el equilibrio en los pacientes de parkinson

ABSTRACT: Parkinson's disease can harm the functional capacity of a person, which may lead to a worse motor coordination and balance, increasing the risk of falls, and consequently to morbidities or even death. So, complimentary therapies to the drug therapy as exercise programs the aim to increase coordination and balance may avoid the possible falls that may occur and to increase the life quality for people with this illness. Thus, the present study is aimed to verify the efficiency of a four-week exercise program formed by balance and motor coordination on people living with Parkinson using Berg scale to evaluate it. Twelve individuals (64.18 ± 9.54 years; 73.83 ± 14.97 kg; 168.25 ± 8.24 cm) were submitted to two sessions each week consisted of exercises divided in three series of 90 seconds, in a total of eight sessions. The Berg scores increase significatively (p = 0.033) from 43.58 ± 6.53 to 46 ± 5.22. Since scores less than 45 mean a high probability of falls, it is possible to say that the applied program was effective in increase the balance for these individuals, consequently, leading to a better functional capacity and a possible better life quality.

RESUMEN: La enfermedad de Parkinson deteriora la capacidad funcional del paciente al afectar su coordinación motora y el equilibrio, lo que puede provocar caídas y, en consecuencia, morbilidades asociadas o incluso la muerte. De esta manera, las terapias auxiliares de la terapia farmacológica, como los programas de ejercicio físico que buscan mejorar la coordinación y el equilibrio, pueden ayudar a evitar el riesgo de caídas y, por lo tanto, mejorar la calidad de vida de las personas afectadas por esta enfermedad. Por tanto, el presente estudio tiene como objetivo verificar la efectividad de un programa de ejercicios de cuatro semanas que incluye ejercicios de equilibrio y coordinación motora para mejorar el equilibrio de las personas con Parkinson, utilizando la escala de Berg. Doce personas (64,18 ± 9,54 años; 73,83 ± 14,97 kg; 168,25 ± 8,24 cm) se sometieron a dos sesiones semanales de ejercicios divididos en tres series de 90 segundos para cada ejercicio, para un total de ocho sesiones. La puntuación de los individuos en la escala de Berg aumentó significativamente (p = 0,033) de 43,58 ± 6,53 a 46 ± 5,22. Sabiendo que los puntajes inferiores a 45 significan una probabilidad considerable de caídas, es posible afirmar que el programa de ejercicio aplicado fue efectivo para mejorar el equilibrio de los individuos y, en consecuencia, puede conducir a una mejora en la capacidad funcional del individuo y una posible mejora en la calidad de vida.

Functional training versus Mat Pilates in motor and non-motor symptoms of individuals with Parkinson's disease: study protocol for a randomized controlled trial

Abstract Aim: This study aims to compare a functional training protocol and Mat Pilates for individuals with Parkinson's disease and to evaluate the effects on motor symptoms, as well as non-motor symptoms using a randomized controlled trial. Methods: Protocol for a randomized clinical trial in which 45 individuals with Parkinson's disease will be recruited and randomly allocated to one of three groups: (1) functional training; (2) Mat Pilates; (3) control group. Both intervention groups will have 60 min classes twice a week for 12 weeks. The primary outcome will be analyzed through motor symptoms, including balance, mobility, muscle strength, handgrip strength, flexibility, range of motion, and cardiorespiratory fitness. Secondary outcomes will include non-motor symptoms such as cognition, aging perspective, mood, anxiety, and depression. Conclusion: This will be the first randomized trial to compare the effects of functional training and Mat Pilates in a population with Parkinson's disease. It is hypothesized that improvements in motor and non-motor symptoms will be greater and more lasting after functional training and Mat Pilates interventions than those that maintain their routine activities, given the benefits of exercise and the unprecedented protocols in this disease.

Hot Topics in Recent Parkinson's Disease Research: Where We are and Where We Should Go / 神经科学通报·英文版

Parkinson's disease (PD), the second most common neurodegenerative disease, is clinically characterized by both motor and non-motor symptoms. Although overall great achievements have been made in elucidating the etiology and pathogenesis of PD, the exact mechanisms of this complicated systemic disease are still far from being clearly understood. Consequently, most of the currently-used diagnostic tools and therapeutic options for PD are symptomatic. In this perspective review, we highlight the hot topics in recent PD research for both clinicians and researchers. Some of these hot topics, such as sleep disorders and gut symptoms, have been neglected but are currently emphasized due to their close association with PD. Following these research directions in future PD research may help understand the nature of the disease and facilitate the discovery of new strategies for the diagnosis and therapy of PD.

The Relationship Between the Gut Microbiome and Neurodegenerative Diseases / 神经科学通报·英文版

Many recent studies have shown that the gut microbiome plays important roles in human physiology and pathology. Also, microbiome-based therapies have been used to improve health status and treat diseases. In addition, aging and neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease, have become topics of intense interest in biomedical research. Several researchers have explored the links between these topics to study the potential pathogenic or therapeutic effects of intestinal microbiota in disease. But the exact relationship between neurodegenerative diseases and gut microbiota remains unclear. As technology advances, new techniques for studying the microbiome will be developed and refined, and the relationship between diseases and gut microbiota will be revealed. This article summarizes the known interactions between the gut microbiome and neurodegenerative diseases, highlighting assay techniques for the gut microbiome, and we also discuss the potential therapeutic role of microbiome-based therapies in diseases.

Effects of resistance training on metabolic and cardiovascular responses to a maximal cardiopulmonary exercise test in Parkinson`s disease / Efeitos do treinamento resistido sobre as respostas metabólicas e cardiovasculares ao teste de esforço cardiopulmonar máximo na doença de Parkinson

ABSTRACT: Objective: To evaluate the effects of resistance training on metabolic and cardiovascular responses during maximal cardiopulmonary exercise testing in patients with Parkinson's disease. Methods: Twenty-four patients with Parkinson's disease (modified Hoehn and Yahr stages 2 to 3) were randomly assigned to one of two groups: Control or Resistance Training. Patients in the Resistance Training Group completed an exercise program consisting of five resistance exercises (two to four sets of six to 12 repetitions maximum per set) twice a week. Patients in the Control Group maintained their usual lifestyle. Oxygen uptake, systolic blood pressure and heart rate were assessed at rest and during cycle ergometer-based maximal cardiopulmonary exercise testing at baseline and at 12 weeks. Assessments during exercise were conducted at absolute submaximal intensity (slope of the linear regression line between physiological variables and absolute workloads), at relative submaximal intensity (anaerobic threshold and respiratory compensation point) and at maximal intensity (maximal exercise). Muscle strength was also evaluated. Results: Both groups had similar increase in peak oxygen uptake after 12 weeks of training. Heart rate and systolic blood pressure measured at absolute and relative submaximal intensities and at maximal exercise intensity did not change in any of the groups. Muscle strength increased in the Resistance Training but not in the Control Group after 12 weeks. Conclusion: Resistance training increases muscle strength but does not change metabolic and cardiovascular responses during maximal cardiopulmonary exercise testing in patients with Parkinson's disease without cardiovascular comorbidities.

RESUMO Objetivo: Avaliar os efeitos do treinamento resistido nas respostas metabólicas e cardiovasculares ao teste de esforço cardiopulmonar máximo em pacientes com doença de Parkinson. Métodos: Vinte e quarto pacientes com doença de Parkinson (estágios 2 a 3 de Hoehn e Yahr modificado) foram aleatoriamente randomizados em dois grupos: Controle e Treinamento Resistido. O Grupo Treinamento Resistido realizou, duas vezes por semana, cinco exercícios resistidos, duas a quatro séries, seis a 12 repetições máximas por série. O Grupo Controle manteve seu estilo de vida. No início e após 12 semanas, consumo de oxigênio, pressão arterial sistólica e frequência cardíaca foram avaliados em repouso e durante um teste de esforço cardiopulmonar máximo realizado em um cicloergômetro. As avaliações durante o exercício foram realizadas nas intensidades submáximas (a inclinação da regressão linear entre as variáveis fisiológicas e as cargas absolutas), nas intensidades submáximas relativas (limiar anaeróbico e ponto de compensação respiratória) e na intensidade máxima (pico do exercício). Adicionalmente, foi avaliada a força muscular. Resultados: Comparado com o início, o consumo de oxigênio pico aumentou, de forma semelhante, em ambos os grupos após 12 semanas. A frequência cardíaca e a pressão arterial sistólica avaliadas nas intensidades submáximas absolutas e relativas, assim como no pico do exercício, não se modificaram em nenhum dos grupos. Finalmente, diferente do Grupo Controle, a força muscular aumentou no Grupo Treinamento Resistido após 12 semanas. Conclusão: Em pacientes com doença de Parkinson sem comorbidades cardiovasculares, o treinamento resistido aumenta a força muscular, mas não modifica as respostas metabólicas e cardiovasculares ao teste de esforço cardiopulmonar máximo.

Terapia de produção audiovisual associada a estimulação por corrente contínua melhora nomeação em paciente com afasia de Broca e doença de Parkinson / Audiovisual production therapy associated with transcranial current stimulation improves naming in a patient with Broca's aphasia and Parkinson's disease

RESUMO A doença de Parkinson (DP) é uma doença neurodegenerativa, caracterizada por disfunções motoras e não motoras. Pacientes com DP também podem apresentar problemas de linguagem, incluindo deficit em tarefas de nomeação. Dificuldade em tarefas de nomeação é uma característica importante da afasia de Broca, transtorno de linguagem associado a lesões pós-acidente vascular cerebral (AVC) no córtex pré-frontal inferior esquerdo (área de Broca). Aqui, apresenta-se o caso de um paciente de 79 anos diagnosticado com DP (estágio 4 na escala de Hoehn e Yahr) e afasia crônica não fluente pós-AVC, com deficit de nomeação severos. O paciente foi tratado com uma nova combinação de terapia audiovisual de produção e estimulação transcraniana por corrente contínua (ETCC), técnica neuromodulatória não invasiva, que tem sido cada vez mais adotada para potencializar terapias fonoaudiológicas. ETCC anodal (2 mA) foi aplicada sobre o córtex pré-frontal inferior esquerdo (F7 no sistema 10/20), durante nove sessões de 20 minutos, ao longo de duas semanas, enquanto o paciente tentava nomear imagens de objetos comuns com o auxílio de vídeos curtos mostrando uma boca articulando os sons do nome do objeto (pista audiovisual). Observou-se aumento significativo nos escores de nomeação entre o pré e o pós-tratamento, tanto para imagens treinadas, quanto para não treinadas, mas fonemicamente similares (generalização). Os resultados apresentaram indícios iniciais de que terapia audiovisual de produção associada à ETCC anodal sobre a área de Broca pode representar uma alternativa viável para pacientes com deficits de nomeação severos.

ABSTRACT Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor and nonmotor symptoms. PD patients may present language problems, including deficits in confrontation naming. Naming deficits are also an important feature of Broca's aphasia, a condition associated with post-stroke damage to the left inferior prefrontal cortex (Broca's area). We present the case of a 79-year old, male patient diagnosed with both PD (stage 4 in Hoehn and Yahr's scale) and chronic post-stroke, non-fluent aphasia. The patient, with particularly severe naming deficits, was treated with a novel combination of audiovisual production therapy and transcranial direct current stimulation (tDCS), a noninvasive neuromodulatory technique that has been increasingly used to potentiate speech therapy. Anodal tDCS (2 mA) was applied to the left inferior prefrontal cortex (F7 in the 10/20 system) in nine 20-min sessions over two weeks while the patient tried to name pictures of common objects aided by short videos of an articulating mouth (audiovisual cue). We found significant pre- to post-training naming improvement for treated items and for untreated, phonemically similar items (generalization). The results provide initial indication that audiovisual production therapy combined with anodal tDCS over Broca's area may represent a viable treatment alternative for patients with severe naming deficits.

Jules Bernard Luys: from a description of the subthalamic nucleus to hypnotism / Jules Bernard Luys: da descrição do núcleo subtalâmico ao hipnotismo

ABSTRACT The authors review the role of Jules Bernard Luys in the discovery of the subthalamic nucleus (STN) over 150 years ago. The relationships between the STN and movement disorders, particularly hemiballismus and Parkinson's disease, are well known. The academic life of Jules Bernard Luys can be divided into two periods: a brilliant start as a neuroanatomist, culminating in the discovery of the STN, followed by a second period marked by a shift in his academic activity and an increased interest in topics such as hysteria, hypnotism and, eventually, esotericism.

RESUMO Os autores revisam o papel de Jules Bernard Luys na descoberta do núcleo subtalâmico (NST) há mais de 150 anos. As relações da NST com distúrbios do movimento, em particular o hemibalismo e a doença de Parkinson, são bem conhecidas. A vida acadêmica de Jules Bernard Luys pode ser dividida em duas fases: a primeira, um brilhante começo de sua carreira como neuroanatomista, culminando na descoberta do NST, seguido por um segundo período marcado por uma mudança em sua atividade acadêmica, e maior interesse em tópicos como histeria, hipnotismo e finalmente esoterismo.

Landmarks for the Location of the Subthalamic Nucleus Using Magnetic Resonance Imaging

Deep brain stimulation has become an option for advanced Parkinson's disease treatment since the 1990s, but the first reports are from Benabid's team, a French neurosurgeon, in the 1980s. The subthalamic nucleus (STN), more specifically its dorsolateral portion, is the most commonly stimulated brain area. One of the major aspects for a good surgical result is the accurate location of this target. Therefore, the present article aimed to identify landmarks that facilitate and refine the location of the STN using nuclear magnetic resonance imaging (NMRI) of the skull. In order to achieve this goal, a search for articles was performed using the PubMed and Science Direct online databases, and articles regarding the use of NMRI to target STN were included. The precise location of the dorsolateral portion of the STN is fundamental to achieve the best possible effect on motor symptoms and to minimize side effects. One of the most used location methods is the NMRI, associated or not with tomography or ventriculography. The location strategies can be classified as direct and indirect. Landmarks are among the indirect strategies, and the most important ones (red nucleus, Sukeroku sign, dent internal capsule sign, supramammillary commissure, mammillothalamic tract, and interpeduncular cistern) are described in the present article. The various landmarks can be combined to locate with more accuracy the dorsolateral portion of the STN and the ideal position of the electrodes to achieve the best possible clinical result.
