ABSTRACT
Resumen Introducción: La cinetosis se relaciona con la presencia de una serie de síntomas que comúnmente son inducidos por situaciones cotidianas de viajes en medios de transporte. Una forma utilizada por décadas para determinar el grado de susceptibilidad a la cinetosis ha sido con la aplicación del cuestionario en su versión acortada Motion Sickness Suscep-tibility-short (MSSQ-short). Objetivo: Adaptar lingüística y transculturalmente al español el cuestionario MSSQ-short. Material y Método: Se llevaron a cabo cuatro etapas: Traducción directa, traducción inversa (retrotraducción), consolidación por un comité de expertos y pretest (aplicabilidad/viabilidad). En la etapa de pre-test 51 personas respondieron el cuestionario. Resultados: La discrepancias encontradas en las primeras etapas fueron resueltas por un tercer traductor, el cual concluyó en un documento final en español que fue analizado y revisado por el comité de expertos. Se determinaron los percentiles del 0 al 100, percentil 50 con 9,0 puntos, percentil 25 con 2,13 puntos y el percentil 75 con 17,4 puntos. La consistencia interna del cuestionario fue de 0,889. Conclusión: La traducción y adaptación transcultural fue aceptada por un comité de expertos y participantes con distintas características demográficas y educacionales. El cuestionario obtuvo buena consistencia interna y resultados concordantes con la versión original.
Abstract Introduction: Motion sickness is related to the presence of a series of symptoms that are typically induced by everyday situations of travel in means of transport. A way used for decades to determine the degree of susceptibility to motion sickness has been with the application of the questionnaire in its shortened version Motion Sickness Susceptibility-short (MSSQ-short). Aim: Linguistically and cross-culturally adapt the MSSQ-short questionnaire to Spanish. Material and Method: Four stages were carried out: direct translation, reverse translation (back translation), consolidation by a committee of experts, and pretest (applicability/feasibility). In the pre-test stage, 51 people answered the questionnaire. Results: The discrepancies found in the early stages were resolved by a third translator, which concluded in a final document in Spanish that was analyzed and reviewed by the expert committee. The percentiles from 0 to 100 were determined, 50th percentile with 9.0 points, 25th percentile with 2.13 points, and 75th percentile with 17.4 points. The internal consistency of the questionnaire was 0.889. Conclusion: The cross-cultural translation and adaptation were accepted by a committee of experts and participants with different demographic and educational characteristics. The questionnaire obtained good internal consistency and results consistent with the original version.

PURPOSE: The purpose of this study was to evaluate whether the symptoms of migraine and car sickness coexist or not. In addition, we tried to elucidate whether the car sickness can be a clinical indicator of diagnosing migraine in children. METHODS: A total of 166 children and adolescents who had newly diagnosed migraine and followed up for more than 2 years after the termination of treatment were involved in the study. The co-morbidity or co-existence of symptoms between two conditions in the clinical course was investigated. RESULTS: Sixty three of 124 who had car sickness as well as migraine recovered from migraine. Among these 63 patients, the car sickness disappeared in 44 (69.8%), decreased in 7 (11.1%) and persisted in 12 (19.0%). On the other hand, 23 of those 124 migraineurs continued to have migraine. In these patients, car sickness disappeared in 4 (17.4%), decreased in 5 (21.7%) and persisted in 14 (60.9%). The freedom or alleviation of car sickness is more common in children free from migraine than in children with persistent migraine (P<0.001). CONCLUSION: The results suggest that migraine is closely related to car sickness in children and the clinical course of migraine generally overlaps those of car sickness. We therefore believe that car sickness can be a clinical indicator in the diagnosis of migraine.
