ABSTRACT
SUMMARY OBJECTIVE: Use Lead-DBS software to analyze stereotactical surgical outcome of an operated population and demonstrate that small target deviations do not compromise the stimulation of desired structures, even with small amperages. METHODS: Image exams of patients submitted to deep brain stimulation for movement disorders treatment were processed in Lead-DBS software. Electrode stereotactic coordinates were subtracted from the planned target and those deviations, compared among different anatomical targets and sides operated firstly and secondly. We also quantified the frequency of relation between the activated tissue volume and the planned target through computer simulations. RESULTS: None of the 16 electrodes were exactly implanted at the planned coordinates. A stimulation of 3 mA reached 62.5% of the times the planned coordinates, rising to 68.75% with a 3,5 mA. No statistical significance was demonstrated in any comparison of laterality and anatomical sites. CONCLUSIONS: The simulation of small amperage fields could reach the intended target even when electrode placement is suboptimal. Furthermore, such a goal can be achieved without overlapping the volume of activated tissue with undesired structures. Software Lead-DBS proved to be a valuable complementary asset for surgical stereotactical result assessment.

Introdução: A marcha pode ser definida como um padrão cíclico, na postura bípede, que utiliza os membros inferiores para propulsão do corpo. No campo da Neurologia, a marcha no exame físico representa sinais na avaliação neurológica, que auxiliam no fechamento de diagnósticos. No ambiente clínico, em especial nos consultórios, o refinamento da avaliação da marcha fica restrita a experiência do clínico, pois o espaço muitas vezes é reduzido, o tempo inadequado para avaliação. Poucos relatos na literatura abordaram a referida questão. Objetivo: Discutir os principais pontos da análise de marcha de interesse dos neurologistas, no consultório. Metodologia: Nessa revisão narrativa, foram levantados 32 artigos e, aplicados os critérios de elegibilidade, foram selecionados 6 artigos. A avaliação da marcha no consultório deve respeitar critérios, pois pode acarretar vieses dos parâmetros da marcha e dificultar a análise global. Conclusão: Por isso, há necessidade de maiores discussões, no âmbito do consultório, para melhor avaliar os parâmetros da marcha. (AU)
Introduction: Gait can be defined as a cicle pattern in biped posture that use to lower limb to body propulse. In Neurology, the physical exam of gait represents a neurological signal. This fact can help in the diagnosis conclusion. In a clinical setting and medical office, the critical evaluation is restricted to the physician´s expertise. The space of doctor´s room is often reduced and inappropriate time for evaluation. Objective: This study aimed to discuss the main points of gait analysis in neurological outpatients. Methods: In this narrative review, 32 articles were analyzed, and after included criteria, 6 articles were selected. In neurology medical office must respected criteria to no promote bias of gait parameter and complicate global assessment. Conclusion: Therefore, there is a need for further discussions, within the scope to better assess the gait parameters. (AU)

Introdução: As injúrias neurológicas apresentam distúrbios de movimentos que prejudicam a funcionalidade e independência desses pacientes. A espasticidade é um dos distúrbios mais frequentes e acarreta complicações secundárias com interferência negativa nas funções físicas e motoras desempenhadas na vida cotidiana. O objetivo do presente estudo foi revisar na literatura evidências que expõem o efeito da vibração focal na espasticidade de pacientes com injúrias neurológicas. Metodologia: Realizou-se uma busca nas bases e banco de dados Pubmed, PEDro, Scopus e Web of Science utilizando os descritores "focal vibration" AND "spasticity" estipulando critérios de inclusão e de qualidades metodológicas. No total cinco artigos foram incluídos e compuseram a revisão. Resultados: Os resultados evidenciaram melhoras significativas na redução da espasticidade e em parâmetros funcionais que influenciam na qualidade de vida destes pacientes. Conclusão: Conclui-se então que a vibração focal é uma intervenção eficaz na redução da espasticidade de pacientes com injúrias neurológicas. (AU)
Introduction: Neurological injuries present movement disorders that impair the independence of these patients. Spasticity is one of the most frequent disorders and results in secondary complications with negative interference in physical and motor functions performed in daily life. The purpose of this study was to review evidence in the literature that exposes the effect of focal vibration on spasticity in patients with neurological injuries. Methodology: A search was performed in the databases Pubmed, PEDro, Scopus and Web of Science using the descriptors "focal vibration" AND "spasticity" stipulating inclusion criteria and methodological qualities. 5 articles were included and made up the review analysis. Results: The results showed significant improvements in the reduction of spasticity and in functional parameters that influence the quality of life of these patients. Conclusion: We concluded that the focal vibration is an effective intervention in reducing spasticity in patients with neurological injuries. (AU)
