The aim of this study is to collect a large set of norm/control data on an instrumented treadmill (the Gait Real-time Analysis Interactive Lab - GRAIL) at the university hospital of Ghent for the purpose of clinical studies as well as for clinical interpretation. We hypothesize that this norm/control data will provide reference data of the normal gait patterns in the healthy population such that we can then use it to identify gait abnormalities in populations with pathology. The following data will be collected on the GRAIL while subjects walk at different gait speeds: 3D kinematics, kinetics, and EMG. Additionally, 3D kinematics, kinetics, and EMG data will be collected when performing either a cognitive (Stroop Color and Word Test) or motor (requiring arm swing) dual-task while walking at comfortable walking speed.

Participants will be asked to walk at different gait velocities for 1 minute. The treadmill speed will be increased incrementally at 0.1m/s intervals until just before running.
Participants aged between 6 and 17 years will be asked to walk at comfortable walking speed while playing either a cognitive (Stroop Color and Word Test) or motor (requiring arm swing) game.
