Introduction: A Gait initiation requires the movement from a stable double leg stance to the dynamic state ofwalking. Methode: The motion of participants was tracked (eight-camera motion analysis system,200Hz (Qualisys Sweden)) using reflective markers attached to the lower limbs. An initial static trial was used to establish the relationship among the markers and their respective segment markers. This allowed the tracking of dynamic movements using the markers. Findings: The least amounts of lateral deviation were found on artificial turf. The longest steps were found on granolith floor covering and the shortest ones were found on artificial turf. The widest steps were found on hard floor and the least amounts of width were found on PVC floor covering. The longest step times were found on artificial turf and the shortest step times were found on PVC floor covering. The longest swing phase times were found on artificial turf and the shortest swing phase times were found on PVC floor covering. The fastest steps were found on granolith floor covering and the slowest ones were found PVC floor covering. Conclusion: Kinematic characteristics of gait initiation on different floor covering are not the same, and facing new floor covering operate as a serious perturbation. It is suggested to plan for training and rehabilitation activity on the same surface as the real game court.
