Comparación cuantitativa de la ejecución de la maniobra de Lachman para su estandarización a través de software para dispositivo móvil
Abstract
Introduction: the Lachman maneuver was amplified as a diagnostic resource to detect injuries in the anterior cruciate ligament (ACL) and it tends to be thought, due to its simplicity, that there is no significant accumulation in its execution. This comparative study focuses on using the sensors integrated into a mobile device to find out whether the intraobserver or interobserver variations are significant, through the intraclass correlation coefficient.
Materials and methods: two trials called “Lachmatón” will be carried out with twelve orthopedic residents as evaluators and test subjects; the first trial helped to identify and describe the differences in performance gestures between raters, while the second allowed measuring the increase in performance similarity between raters as instructors, in contrast to the first trial, where neither could instruction; This was possible by measuring the similarity of the statistical and morphological characteristics of the signals obtained through the intraclass achievement index.
Results: two important gestures were identified, which emit signals in different ways when applied or not to the execution of the maneuver: 1) fix the foot and, 2) fix the femur. You will find that there is a significant difference between you and the evaluators.
Conclusion: the use of sensors integrated into a mobile device to measure differences in the execution of the Lachman maneuver helped to determine the gestures that allow a greater reproducibility of this maneuver.
