A public dataset of overground walking kinetics and full-body kinematics in healthy adult individuals
Description
The dataset comprises raw kinetic and full-body kinematic data (both in .c3d and .tsv) of 57 healthy subjects (29 females, 28 males; M age: 23.1 years, SD 2.7; M body height: 1.74 m, SD 0.10; M body mass: 67.9 kg, SD 11.3; M body mass index: 22.2 kg/m², SD 2.0) during overground walking. All subjects were without gait pathology and free of lower extremity pain or injuries. The .c3d files are named in the following format: S{subject_id}_{trial number}_{static/gait}.c3d. Separate text files were generated for the kinematic marker trajetories {.tsv} and kinetic force signals of the first {_f_1.tsv} and second {_f_2.tsv} force plate.

Steps to reproduce
The subjects performed 20 gait trials in a single assessment session, while they did not undergo any intervention. The subjects were instructed to walk barefoot at a self-selected speed. In each trial the subjects overall walking distance was approximately 10 m. Kinematic data were recorded using a full-body marker set consisting of 62 retro reflective markers placed on anatomical landmarks. Ten Oqus 310 infrared cameras (Qualisys AB, Sweden) captured the three-dimensional marker trajectories at a sampling frequency of 250 Hz. The three-dimensional ground reaction forces were recorded by two Kistler force plates (90 x 60 cm; Kistler, Type 9287CA, Switzerland) at a frequency of 1000 Hz. For all trials, the subjects stepped with their right foot on the first force plate and their left foot on the second force plate. The recording was managed in time-synchronization by the Qualisys Track Manager 2.7 (Qualisys AB, Sweden). Two experienced assessors attached the markers and conducted the analysis. Every subject was analysed by the same assessor only. The laboratory environment was kept constant during the investigation. Before the data acquisition, each subject performed 20 test trials to get accustomed to the experimental setup and to assign a starting point for a walk over the force plates. This procedure is described to minimize the impact of targeting on the force plates on the observed gait variables. Additionally, the participants were instructed to watch a neutral symbol (smiley) on the opposing wall of the laboratory to direct their attention away from targeting on the force plates and ensure a natural walk with an upright body position.
