Trunk Acceleration Along the Mediolateral Axis in the Lower and Upper Trunk During Walkinga

  • a Pre=before the intervention, Post=after the intervention, RMS=root-mean-square, g=unit of gravity (m/s2). Calibration of the accelerometers against gravity was carried out on a horizontal surface before each test session. Patients walked at 3 self-administered speeds (slow, preferred, and fast) across an 8.5-m marked path. Time was registered during steady-state walking (middle 4.3 m) by photoelectric cells connected to a computerized stopwatch. A velocity of 1.2 m/s (the mean preferred walking speed) was used to explore RMS g values at the lower and upper trunk and upward attenuation along the mediolateral axis.25,26
