[en] INTRODUCTION. Due to the global repercussion of headache in general and tension-type and cervicogenic-type headaches, particularly at a social and health level in all people who suffer it and also at an economic level, it is very important to have tools for its diagnosis, and among them the cervical flexion-rotation test stands out. Therefore, the objective of this study is to assess the relationship between this test and cervicogenic headache as well as its validity and reliability MEHODS. In this literature review, an article search has been carried out following the PRISMA recommendations in five databases (Pubmed, PEDro, Scopus, WOS and Cochrane). To carry out this search, the keywords "cervicogenic headache" and "Flexion-Rotation test" have been used, and the inclusion criteria have been studies published in the last 15 years, carried out in humans, whose language is English or Spanish. and whose types of studies are observational and comparatives, systematic reviews, meta-analysis. RESULTS. After carrying out the search in the databases, a total of 9 articles who speaks about the Flexion-Rotation test in cervicogenic headache and the validity of the test were selected. 8 were observational comparative studies and 1 a systematic review, obtaining very positive results in the test. CONCLUSION. With the information obtained in the articles, it is concluded that the cervical flexion-rotation test presents high sensitivity and specificity, as well as a proven validity for the diagnosis of cervicogenic headache. It is also considered necessary that in the future research be continued in this line, reducing the limitations that have been present up to now in the studies that have been carried out.

[gl] INTRODUCIÓN Dada a grande repercusión mundial que ten a forma xeral da cefalea, e a tensional e a cervicoxénica en particular tanto a nivel social e de saúde en todas as persoas que a sofren, como a nivel económico, tórnase moi relevante ter ferramentas para o seu diagnóstico, e entre elas destaca o test de Flexión-Rotación cervical. Por conseguinte o obxectivo desde test é valorar a relación entre este test e a cefalea cervicoxénica así como como a súa validez e fiabilidade. MATERIAL E MÉTODO Nesta revisión bibliográfica realizouse unha búsqueda de artigos, seguindo as recomendacións de PRISMA, en cinco bases de datos (Pubmed, PEDro, Scopus, WOS e Cochrane). Para levala a cabo empregáronse as palabras clave "cefalea cervicogénica" e "test de Flexión-Rotación", e os criterios de inclusión foron estudos publicados nos derradeiros 15 anos, realizados en humanos, cuxo idioma sexa inglés ou castelán e cuxos tipos de estudo sean observacionais e comparativos, revisións sistemáticas, metaanálise. RESULTADOS Despois de realizar a búsqueda nas bases de datos mencionadas seleccionáronse un total de 9 artigos que trataban sobre o test de Rotación-Flexión na cefalea cervicoxénica e sobre a validez do test. 8 foron estudos comparativos observacionales e 1 unha revisión sistemática, obtendo resultados moi positivos na proba. CONCLUSIÓN Coa información obtida nos artigos conclúese que o Test de Flexión-Rotación cervical presenta unhas altas sensibilidade e especificidade, así como unha demostrada validez para o diagnóstico da cefalea cervicoxénica. Igualmente considérase necesario que no futuro se continúe investigando nesta liña reducindo as limitacións presentes ata a data de hoxe nos estudos que se levaron a cabo.
