Least squares parameter estimation of the gain between squared wave speed and stress. (a) Trial-specific calibrations (top) were performed using data collected at a single posture and loading rate. (b) Subject-specific calibrations (middle) were performed by including data from all postures and loading rates tested for a given subject. (c) Group calibration (bottom) was performed by including all wave speed and stress data from isometric tasks performed by all subjects. Red symbols represent data used for the three calibration approaches.
