Full Body Motion Capture of Single Individuals Following External Perturbations from Different Directions

This dataset is composed of C3D files corresponding to full body motion of participants undergoing external perturbation at shoulder height with different sensory conditions. The temporal force profiles of the perturbations are also available.

The following experiment received ethical approval from an ethics committee and all participants signed an informed consent form relative to the processing of their data. The experiments were carried on 21 healthy young adults (10 females, 11 males). All were between 20 and 38 yo with a mean age of 27.2 (std: 4.2). Mean mass was 70.2 (std: 12.1) kg and height was 1.74 (std: 0.08) m. 

Participants motion was recorded using 45 reflective markers and a 23 Qualisys camera system (200Hz). The markers were placed on participants following standardised anatomical landmarks. The output signal of the force sensor was processed using a Butterworth low pass filter with a 5Hz cutoff frequency without phase shift. The force sensor was synchronised with the motion capture software.Tree reflective markers were also placed along the pole in order to retrieve the exact direction of the perturbations.
