Multiple motor tasks while walking in patients with chronic bilateral and unilateral vestibulopathy

This dataset contains whole body movements (i.e. 3D trajectories) and 3D kinematics from 30 subjects (10 with bilateral vestibulopathy, 10 with unilateral vestibulopathy, and 10 healthy subjects) during multiple motor tasks while walking: change of speed, double task, gait with eyes closed, gait with head horizontal turns, gait with head vertical turn, step over an obstacle, gait and U-turn. Participants were instrumented with 35 reflective placed on the whole body according to the Convention Gait Model 1.0. A 12-camera motion capture system (Oqus 7+, Qualisys, Göteborg, Sweden), set at a 100 Hz sampling frequency, was used to track cutaneous reflective markers. The marker trajectories were labeled using Qualisys Tracking Manager software (QTM 2019.3, Qualisys, Göteborg, Sweden) and exported in the C3D file format. Joint kinematics were calculated from the raw data of the marker trajectories and stored in C3D files.
