Diseño y construcción de un sistema vestible para inclinometría

Abstract

Accurate analysis of cervical range of motion is essential in the fields of biomechanics and rehabilitation; it serves to detect functional joint injuries. This study presents the development and evaluation of CerviTec, a low-cost wearable system based on inertial sensors, designed to measure cervical angulation and reduce uncertainty from traditional methods such inclinometry. The performance of this device was compared against a bubble inclinometer and values reported in the literature. CerviTec achieved high accuracy in five out of six evaluated cervical movements, showing a behavior comparable to more complex commercial systems. Right rotation presented greater variability, aligning with previous studies that highlight technical challenges in measuring axial movements. However, CerviTec proved to be a promising, accessible, and efficient tool for clinical enviroments with limited resources. These findings support its potential application in functional assessment and rehabilitation, validating the hypothesis: a wearable inertial system can provide measurements comparable to conventional tools.
