Correction to: Trunk Reaction Time and Kinematic Changes Following Slip Perturbations in Subjects with Recurrent Low Back Pain

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."
