ABSTRACT

Background: Dystonia is a heterogeneous disorder that, when refractory to medical treatment, may have a favorable response to deep brain stimulation (DBS). A practical way to have an overview of a research domain is through a bibliometric analysis, as it makes it more accessible for researchers and others outside the field to have an idea of its directions and needs. Objective: To analyze the 100 most cited articles in the use of DBS for dystonia treatment in the last 30 years. Methods: The research protocol was performed in June 2019 in Elsevier’s Scopus database, by retrieving the most cited articles regarding DBS in dystonia. We analyzed authors, year of publication, country, affiliation, and targets of DBS. Results: Articles are mainly published in Movement Disorders (19%), Journal of Neurosurgery (9%), and Neurology (9%). European countries offer significant contributions (57% of our sample). France (192.5 citations/paper) and Germany (144.1 citations/paper) have the highest citation rates of all countries. The United States contributes with 31% of the articles, with 129.8 citations/paper. The publications are focused on General outcomes (46%), followed by Long-term outcomes (12.5%), and Complications (11%), and the leading type of dystonia researched is idiopathic or inherited, isolated, segmental or generalized dystonia, with 27% of articles and 204.3 citations/paper. Conclusions: DBS in dystonia research is mainly published in a handful of scientific journals and focused on the outcomes of the surgery in idiopathic or inherited, isolated, segmental or generalized dystonia, and with globus pallidus internus as the main DBS target.

RESUMO

Introdução: A distonia é uma doença heterogênea que, quando refratária ao tratamento medicamentoso, pode ter uma resposta favorável à estimulação encefálica profunda (EEP). Uma forma prática de ter uma visão desta área de pesquisa é por meio de análise bibliométrica, pois permite aos pesquisadores e terceiros a terem uma ideia das tendências e necessidades da área. Objetivo: Analisar os 100 artigos mais citados no tratamento de distonia pelo uso de EEP nos últimos 30 anos. Métodos: O protocolo de pesquisa foi realizado em junho de 2019 através da base de dados Scopus da Elsevier, em que se obteve os artigos mais citados na área de tratamento de distonia com EEP. Analisaram-se variáveis como autores, ano de publicação, país, afiliação, e alvos de EEP. Resultados: Os artigos foram principalmente publicados principalmente na Movement Disorders (19%), no Journal of Neurosurgery (9%), e na Neurology (9%). Os países europeus oferecem contribuições significativas (57% da amostra). A França (192,5 citações/artigo) e a Alemanha (144,1 citações/artigo) possuem as mais altas taxas de citações dentre todos os países. Os Estados Unidos contribuem com 31% dos artigos da amostra (129,8 citações/artigo). As publicações focaram em Desfechos gerais (46%), seguido de Desfechos a longo prazo (12,5%), e Complicações (11%). O principal tipo de distonia pesquisado foi distonia generalizada ou segmentar, idiopática ou hereditária, isolada, abrangendo 27% dos artigos e 204,3 citações/artigo. Conclusões: A pesquisa de EEP em distonia é publicada em seletos periódicos científicos e foca nos desfechos da cirurgia, nas distonias generalizadas ou segmentares, idiopáticas ou hereditárias, isoladas, sendo o globus pallidus internus o principal alvo da EEP.
