Response to the 'Letter to the Editor' by Ramsey et al. [Med. Eng. Phys. 36 (2014) 805]

摘要

To the Editor, The algebraic calculations in our technical note, entitled "Determination of body segment masses and centers of mass using a force plate method in individuals of different morphology", has been criticized by Ramsey et al. [1]. They claimed that we have defined "a single variable x_s with two different, incompatible geometric definitions, to solve erroneously for the segmental mass (m_s) and center of mass position (x_s)". We would like to thank them for bringing this error to our attention. We revised partially Eqs. (5), (6), and (8), as well as Fig. 2 to solve the incompatibility of using "a single variable x_s" in Figs. 1 and 2. Section "2.2 Modified force plate method" of the technical note [2], which includes all the revisions is presented below.
