Root mean square (RMS) accelerations (m.s-2) measured by the InertiaCube3 (IC3) and Vicon systems.

NOTE: ns = difference between the IC3 and Vicon measures (delta) was not significantly different between the older and younger participant groups.Data are mean (SD) anteroposterior (AP), mediolateral (ML) and vertical (VT) RMS accelerations. Delta represents the difference between the InertiaCube3 and Vicon accelerations.注：ns指代老年与青年受试者组间，惯性立方3（InertiaCube3，IC3）与Vicon测量值的差值（即delta）不存在显著组间差异。本次数据为前后向（anteroposterior, AP）、内外向（mediolateral, ML）与垂直向（vertical, VT）的均方根加速度（Root Mean Square, RMS）的均值（标准差）。Delta指代InertiaCube3与Vicon加速度测量值的差值。
