Assessing the degree of a person’s postural performance constitutes a high-value clinical and therapeutic
tool. Different tests and clinical scales are applied to quantify the postural performance. The different
technologies used to study the postural performance and the limitations of the hardware used in the
captures cause that the results can not be objectively compared. On the other hand, the high costs of
specialized laboratories have led to an increase in the use of the Kinect sensor to assess posture. However,
this is not yet fully accepted as a clinical tool by the scientific community. In this work, an experiment
was conducted to verify if the Kinect is sensitive enough to detect the differences between two age
groups (older and younger) with respect to their postural performance. The application of hypothesis
tests allowed to verify that there are significant differences between both groups, which shows that the
Kinect sensor can be used to perform studies of postural performance.

Valorar el grado de rendimiento postural de una persona constituye una herramienta clínica y terapéutica
de alto valor. Para cuantificar el rendimiento postural se aplican diferentes exámenes y escalas clínicas. Las
diferentes tecnologías empleadas para estudiar el rendimiento postural y las limitaciones del hardware
empleado en las capturas provoca que los resultados no se puedan comparar objetivamente. Por otro
lado, los altos costos de laboratorios especializados han provocado un aumento en la utilización del
sensor Kinect para evaluar la postura. Sin embargo, éste no es aun completamente aceptado como una
herramienta clínica por la comunidad científica. En este trabajo se realizó un experimento para comprobar
si el Kinect es lo suficientemente sensible como para detectar la diferencias existentes entre dos grupos
etarios (adultos mayores y jóvenes) con respecto a su rendimiento postural. La aplicación de pruebas de
hipótesis permitió comprobar que existen diferencias significativas entre ambos grupos, lo cual demuestra
que el sensor Kinect puede ser empleado para realizar estudios de rendimiento postural.
