BackgroundPercussion is an important part of the neurological examination and reflex hammers are necessary to obtain it properly.ObjectiveWe aimed to review the historical aspects of the main reflex hammers and to define the favorite one of Brazilian neurologists.MethodsWe searched original and review articles about historical aspects of the reflex hammers in Scielo and Pubmed and conducted an online survey to investigate the favorite reflex hammer of Brazilian neurologists.ResultsIn the first part, we describe the major milestones in the creation of the reflex hammers. Following, we exhibit the results of the online survey: Babinski-Rabiner was the most voted.ConclusionsThe origins of the reflex hammers goes back long before their creation, from a basic clinical examination method: percussion. Since the description of deep tendon reflexes and the creation of percussion hammers, much has been improved in this technique. Among all the hammers surveyed, the Babinski-Rabiner was the chosen one by a significant portion of Brazilian neurologists.
