'On the impact of the identification of inertial sensors location on the estimation of segment and body centers of mass in transfemoral amputees: a sensitivity study' - Dataset

Gait data of a subject with transfemoral amputation. The subject was equipped with a set of 5 magneto-inertial measurement units (MIMUs) (Xsens Technologies B.V., Enschede, The Netherlands, 100 sample·s-1) located on the trunk (over the sternum), both prosthetic and sound thighs (ThighP, ThighS) and shanks (ShankP, ShankS) and a set of 59 reflective markers positioned on the patient’s anatomical landmarks. The participant was asked to walk in a straight line at his natural speed along an 8 m pathway with three force plates (AMTI, Advanced Mechanical Technology, Inc, Massachussets, USA, 1000 Hz) in its middle. Data acquisition was performed over a total of 6 trials. For each trial, only the prosthetic stride performed at steady state walking speed and occurring on the force plates was considered.

All relevant data are within the structure “Data.mat”. This structure array contains reference acceleration data from the force platforms, position data of the segments center of mass (SCoM) and of the MIMUs obtained using the positions of optical motion capture (OMC) markers and data fromMIMUs. All data are already synchronized.
