Abstract:
This erratum is to correct the force plate device presented in the Methods section, subsection "Data Collection." A pressure mat, rather than a force plate was used with the ActiveStep® treadmill to measure ground reaction forces. The third sentence of the second paragraph should read as: "The pressure mat (GAITRite, Sparta, NJ) was installed, and a computer-controlled triggering mechanism would release the movable belt on the platform." Additionally, the first sentence of the third paragraph in the same section should read as: "The flexion angle was measured at heel strike of the first step only, and flexion angle at toe-off was measured at first step only (represented in degrees) by the IMU sensor and the pressure mat."
