Stabilometric postural for Inertial Measurement Unit (IMU) @Signal Processing Symposium - State University of Campinas (UNICAMP)


Abstract: Inertial sensors have been proposed for posture balancing measures due to its portability features and lower costs. However, the questionable accuracy of the positioning data produced by these devices still confers the dubious credibility of the results. Our objective was to develop a stabilometric analysis from a mobile Inertial Measurement Unit (IMU) data with an individual in semi-static posture. The data were collected in a pilot program with a young and healthy individual who remained as standing as possible in orthostatic position with the mobile attached to the patient's waist. These data were processed on a computer by specific App and integrated into an IMU. The anteroposterior and mid-lateral oscillation data were generated on Matlab software by subtracting of each real pitch and roll angle from the median of each motion axis. The pitch and roll median data were crossed to obtain the Body Mass Center (COM) graphic analysis by IMU.
