- Abstract
The objective of this work is to evaluate the reliability of the measurement of the instantaneous axis of rotation (EIR) of the cervical spine by means of a video analysis technique of low cost, as well as to design a technique that minimizes the errors. The information was obtained from technical and anatomical markers located in 7 healthy subjects, with three experimental sessions for subject, measured by two different operators. The movement registered by means of the video camera of a smartphone, to 30 fps. The videos were analyzed by means of the free software Tracker, and the kinematic calculations (positions, speeds, accelerations and EIR) were realized by proper software developed in MATLAB. A reliability analysis was realized calculating the intraclass correlation coefficient (ICC) and the standard error mean (SEM) between operator and between sessions. The values obtained for the SEM and ICC are acceptable or good, showing the possibilities of the use of techniques of low cost in biomechanical applications, what opens very interesting possibilities in fields like the functional assessment.
