The database constists of data from 15 subjects (eleven healthy subjects and four PD patients) that performed the 4×10 m straight walking tests. All subjects gave written informed consent. Details on the subject population is given in .
Data was acquired using two Shimmer3 (Shimmer Research, Dublin, Ireland) sensors laterally attached to the shoes. Data from 3D accelerometer and gyroscope were transmitted to a mobile device. The reference system was a camera-based markerless motion capture (Simi, Unterschleißheim, Germany). Synchronization was assured at the beginning and end of the measurements and the data was aligned accordingly.
