Abstract

Balance is critical in performing daily activities; a total decrease or loss of it becomes a serious problem, since all basic activities are affected. According to the literature, the vestibular system associated with balance decreases its accuracy over the years and, along with other degenerative diseases associated with aging, causes severe falls that can lead to death. Several tests have been proposed to measure the balance. Most of these are clinical tests based on an expert's subjective opinion, which lacks objectivity. In this work, we present a system to measure balance based on data obtained from accelerometers and quaternions. These measurements allow us to analyze the acceleration and drawing representing balance. 24 healthy subjects were measured and analyzed with our system, and the corresponding results are presented.
