Boulet, J. A. M., Templer, J. A. and Hanagud, S. (1989): Computer-Based Simulation of a Human Falling on a Stairway. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1145-1149.

“A numerical simulation of a mathematical model of a human falling (plane motion) down a stairway is described. The simulation begins with an arbitrary initial state of the falling object, and numerically integrates equations of motion for the object as it falls and repeatedly strikes the stairway. Realistic simulation requires the use of nonlinear resistance to join rotations. This nonlinearity is being investigated.”

Templer, J. A., Boulet, J. A. M., Hanagud, S. and Hyde, D. (1989): The Soft Stair: Falls Induced by a Laboratory Stair. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1150-1152.

“This study is part of a research program directed at reducing stair injuries by absorbing much of the impact of a fall. Little is known about human kinetics during falls. The paper describes a laboratory stair that induces subjects to fall, but terminates the tumble before the stair is struck. The trajectory of the falling subjects provides insights into the nature of stair falls, and makes it possible to predict the forces that would be generated at impact.”
