“…The unexpected novel finding of our study is that kinematic features of index finger abductions in PD patients, unlike healthy subjects, changed according to the time lapse between paired electrical stimuli and movement onset, with slower values being observed when 200 ms elapsed between movement onset and paired stimuli for STDT than when paired stimuli were delivered concomitantly with movement onset. Since the performance of PD patients worsens during dual task procedures (32–34), one explanation for the decrease in the mean velocity of index finger abductions during STDT testing in PD patients might be the dual task design of our experimental protocol. However, we can exclude this hypothesis since changes in the mean velocity of index finger abductions were significant only at 200 ms all the intervals tested implied a dual task effect.…”

Evidence shows altered somatosensory temporal discrimination threshold (STDT) in Parkinson’s disease in comparison to normal subjects. In healthy subjects, movement execution modulates STDT values through mechanisms of sensory gating. We investigated whether STDT modulation during movement execution in patients with Parkinson’s disease differs from that in healthy subjects. In 24 patients with Parkinson’s disease and 20 healthy subjects, we tested STDT at baseline and during index finger abductions (at movement onset “0”, 100, and 200 ms thereafter). We also recorded kinematic features of index finger abductions. Fifteen out of the 24 patients were also tested ON medication. In healthy subjects, STDT increased significantly at 0, 100, and 200 ms after movement onset, whereas in patients with Parkinson’s disease in OFF therapy, it increased significantly at 0 and 100 ms but returned to baseline values at 200 ms. When patients were tested ON therapy, STDT during index finger abductions increased significantly, with a time course similar to that of healthy subjects. Differently from healthy subjects, in patients with Parkinson’s disease, the mean velocity of the finger abductions decreased according to the time lapse between movement onset and the delivery of the paired electrical stimuli for testing somatosensory temporal discrimination. In conclusion, patients with Parkinson’s disease show abnormalities in the temporal coupling between tactile information and motor outflow. Our study provides first evidence that altered temporal processing of sensory information play a role in the pathophysiology of motor symptoms in Parkinson’s disease.

“…This finding is consistent with others' 21 and our previous work. 13 A novel finding is the potential impact of tDCS conditions on DTC. Specifically, tDCS condition may have influenced preferential task prioritization on either the cognitive task or the walking activity.…”

“…12 We applied this bi-hemispheric approach to people with PD and observed a lessening (though non-significant) of dual-task cost (DTC) during walking after a single tDCS session. 13 Recent studies suggest anodal tDCS combined with concurrent training (tango dancing, 14 dynamic balance training 15 ) may augment beneficial effects on walking and balance compared with tDCS alone. To our knowledge, the concept of tDCS plus a concurrent activity has not yet been explored in dualtask walking in PD.…”

Resumo: Estimulação Transcraniana por Corrente Contínua (ETCC) é um método de tratamento não invasivo e de baixa intensidade que é utilizada no tratamento de diversas doenças como a depressão, fibromialgia, paralisia cerebral, entre outras. O objetivo do estudo foi investigar os protocolos de utilização da ETCC na excitabilidade cortical em pessoas acometidas pela Doença de Parkinson (DP), por meio da bibliometria. Foram analisados: 17 publicações, entre 2013 e abril de 2017, indexados na base de dados Web of Science e/ou Scopus. Constatou-se que os anos com mais publicações foram 2014 e 2016 e o idioma com maior incidência foi inglês. A Itália foi o país com maior número de artigos publicados e a Europa o continente. Em relação ao tema mais estudado, notouse a utilização da ETCC sobre o equilíbrio e a marcha na DP; já o protocolo mais utilizado esteve relacionado com a colocação do eletrodo do ânodo posicionado sobre o córtex pré-frontal dorsolateral (DLPFC) à esquerda e o eletrodo catódico foi posicionado sobre a área supra-orbitária direita utilizando o método 10-20%, com uma intensidade de 2mA por 20 min. Concluiu-se que a ETCC pode ter efeitos significativos na reabilitação motora e cognitiva em pacientes com DP e que os protocolos analisados fornecem perfil de segurança favorável, tolerabilidade, aplicabilidade e boa relação custo-efetividade em comparação com outras técnicas de tratamento.

The objective of the study was to investigate the protocols for the use of tDCS in cortical excitability in people with Parkinson's disease (PD), through bibliometrics. We analyzed: 17 publications, between 2013 and April 2017, indexed in the Web of Science database and / or Scopus. It was verified that the years with the most publications were 2014 and 2016 and the language with the highest incidence was English. Italy was the country with the highest number of articles published and Europe the continent. Regarding the most studied theme, the use of tDCS on balance and gait in PD was noted; The most used protocol was related to the placement of the anode electrode positioned on the dorsolateral prefrontal cortex (DLPFC) on the left and the cathode electrode was positioned over the right supraorbital area using the 10-20% method, with a Intensity of 2mA for 20 min. It was concluded that tDCS can have significant effects on motor and cognitive rehabilitation in PD patients and that the protocols analyzed provide a favorable safety profile, tolerability, applicability and cost-effectiveness compared to other treatment techniques.Keywords: Transcranial Direct Current Stimulation, Parkinson, Parkinson's disease.
