RESUMEN
Given the relevance of laser application, the objective of this study was to carry out a systematic review to verify the therapeutic effects of laser application on psoriasis plaques. The databases used were PubMED, Scopus, Embase, Cochrane, Web of Science, and in the gray literature: Google Scholar, Open Grey and LIVIVO. A total of 1,227 records were found, after removal of duplicates 851 studies remained for Phase 1 (reading titles and abstracts) and 31 for Phase 2 (reading the full studies) and finally 9 studies remained for this review, 7 randomized and 2 non-randomized. The risk of bias analysis had two studies with moderate risk and seven with high risk. The present study presented evidence that laser application has positive effects such as reduction of psoriasis plaques. However, due to the high risk of bias, there is a need for further studies.

JUSTIFICATIVA E OBJETIVOS: A corrente polarizada pode ser utilizada em diferentes tipos de lesões, contudo a literatura é escassa no campo fisioterapêutico. O objetivo deste estudo foi apresentar por meio de revisão da literatura os efeitos da corrente polarizada e explorar suas diferentes formas de aplicação pela fisioterapia. CONTEÚDO: Utilizaram-se os bancos de dados LILACS, Medlinee Scielo com as seguintes palavras-chave: corrente polarizada;corrente galvânica; corrente farádica; corrente exponencial; correntes Diadinâmicas de Bernard; corrente de alta voltagem;microcorrente; iontoforese. Foram revisadas 13 referências bibliográficas, do período de 1983 a 2009, além do uso de estudos não indexados a essas bases de dados para a contextualização do assunto. Encontrou-se que esse tipo de corrente proporciona benefícios à pacientes com complicações traumato-ortopédicas, neurológicas, desportivas ou até mesmo pós-mastectomia, em virtude de seu efeito analgésico, anti-inflamatório, vascular, eletroestimulador, cicatricial e ósseo. CONCLUSÃO: A analgesia, os efeitos vasculares e cicatriciais são os mais citados pelos estudos encontrados, destacando-se o uso da corrente diadinâmica de Bernard e da corrente de alta voltagem. No entanto, outros estudos deverão ser realizados para que maiores conclusões sejam obtidas.
BACKGROUND AND OBJETIVES: The polarized current can be used in different types of injuries, but the literature is scarce in the physical therapy . The aim of this study was to present through literature the effects of polarized current and explore different ways of applying for physiotherapy. CONTENTS: We used the databases LILACS, Medline and Scielo with the following keywords: polarized current, galvanic current,faradic current; current exponential; diadynamic Bernard; high voltage current, microcurrent, iontophoresis. 13 references were reviewed from the period 1983 to 2009, and the use of other not indexed studies for the contextualization of the subject. Found that this type of current provides benefits to patients with trauma-orthopedic complications, neurological, sports or evenpost mastectomy because of their analgesic effect, anti-inflammatory,vascular, nerve stimulators and bone healing. CONCLUSION: Analgesia, the vascular and tissue healing effects are the most cited studies found by polarized current, especially the use of diadynamic Bernard current and high voltage current. However, other studies should be conducted to further conclusions can be made.
