Abstract
The aim of this study was to determine the accuracy trunk displacement extracted from an inertial motion capture system (IMC) compared to an optical motion capture system (OMC). Participants walked overground while trunk displacement data from IMC and OMC were simultaneously recorded. The resultant trunk speed from both systems during walking and brief standing periods were compared. No differences were found in trunk speed during walking between IMC and OMC. However, trunk speed was greater for the IMC during the transition periods when compared to the OMC (p<0.05). It is concluded that trunk kinematic parameters extracted from IMCs have fair accuracy when compared to a gold standard during walking, but accuracy is reduced and speed is overestimated when recording kinematics around stationary periods.
