dc.description.abstractIntroducción: El MUNIX es una técnica que estima las unidades motoras con mayor reproducibilidad, rapidez y facilidad que los métodos MUNE previos. Se basa en la obtención de un potencial motor (CMAP) y patrones de interferencia por electromiografía de superficie. Son pocos los estudios que demuestran sus valores de referencia, ninguno aplicado a población latinoamericana. Objetivo: Establecer los valores de referencia del MUNIX y del MUSIX en una muestra de adultos sanos, su relación con variables antropométricas y comportamiento entre músculos. Metodología: Estudio descriptivo, corte transversal, con recolección prospectiva de datos. Se realizaron dos tomas por cada músculo (APB, ADM, EDB, TA, FDI) no consecutivas por el mismo evaluador siguiendo el protocolo actualizado de registro de MUNIX (2018). Se estableció un coeficiente de correlación intraclase entre las tomas de cada músculo. Para el análisis se realizó un promedio de los datos. La correlación de variables se realizó por coeficiente de correlación de Pearson y tau (𝝉) de Kendall de acuerdo al tipo de distribución. Se realizó la prueba de Friedman y ANOVA para determinar si hay diferencias estadísticas significativas entre valores de MUNIX y MUSIX y análisis post hoc para determinar los músculos implicados. Resultados: Se recolectaron 82 registros y los datos se presentan en medias, desviación estándar y rango para las variables electrofisiológicas. Se encontró una relación directamente proporcional del MUSIX APB con la edad e inversamente proporcional de MUNIX APB con la edad. APB y ADM no presentan diferencias significativas en el número de unidades motoras medidas por MUNIX y MUSIX. Discusión: La prueba MUNIX y MUSIX tiene resultados similares a los descritos en la literatura para otras poblaciones. Presentan buena a excelente reproducibilidad de los datos. No todos los músculos tienen resultados equiparables de número y tamaño de unidades motoras. Conclusiones: Se obtuvieron los valores de referencia de MUNIX, MUSIX, índice de preservación tenar y mano dividida. APB y ADM son los músculos con menores diferencias electrofisiológicas.

dc.description.abstractIntroduction: The MUNIX is a technique that estimates motor units with greater reproducibility, fast and ease than previous MUNE methods. It is based on obtain a muscle action potential (CMAP) and interference patterns by surface electromyography. There are few studies that demonstrate their reference values, none applied to the Latin American population. Objective: To establish the reference values of the MUNIX and the MUSIX in a sample of healthy adults, their relationship with anthropometric variables and behavior between muscles. Methodology: Descriptive, cross-sectional study, with prospective data collection. Two non-consecutive shots were performed for each muscle (APB, ADM, EDB, TA, FDI) by the same evaluator following the updated MUNIX registration protocol (2018). An intraclass correlation coefficient was established between the shots of each muscle. For the analysis, an average of the data was performed. The correlation of variables was performed by Pearson's correlation coefficient and Kendall's tau (𝝉) according to the type of distribution. The Friedman test and ANOVA were performed to determine if there are significant statistical differences between MUNIX and MUSIX values and post hoc analysis to determine the muscles involved. Results: 82 records were obtained, and data are presented as means, standard deviation and range for electrophysiological variables. A directly proportional relationship was found between MUSIX APB and age and an inversely proportional relationship between MUNIX APB and age. APB and ADM do not present significant differences in the number of motor units measured by MUNIX and MUSIX. Discussion: The MUNIX and MUSIX tests have similar results to those described in the literature for other populations. They exhibit good to excellent data reproducibility. Not all muscles have comparable results in the number and size of motor units. Conclusions: The reference values of MUNIX, MUSIX, thenar preservation index and split hand were obtained. APB and ADM are the muscles with the least electrophysiological differences.eng
