ABSTRACT
Balance control is a fundamental ability to regulate the quasi-static human erect standing, and its assessment is fundamental in providing information regarding the risk of falling The Equimetrix was developed as an affordable and easy to use device that, using a webcam for measuring the migration of the center of mass, and a sensitive mat to measure the base of support, can integrate balance information in the form of a real-time stability index (SI). This work aims at verifying if the SI can differentiate feet positions during static stance and if this discriminatory ability is comparable to traditional balance parameters. Results demonstrate that the SI has a higher predictive capability to detect stable and metastable stances than other traditional parameters, such as the center of mass mean path velocity.
