Kinematic variability (MeanSD) results for trunk velocities in the anterior-posterior (AP), mediolateral (ML), and vertical (VT) directions. Note that the vertical scale is different for the ML direction compared to the AP and VT directions. Nearly all subjects exhibited greater variability during the Control (CO) walking trials, particularly in the AP and VT directions. Variability of ML movements was much greater than that of AP and VT movements. The "*" indicates a statistically significant Subject × Condition interaction effect (p = 0.008).
