progressives come in. From the stationary standing position on top of a block that was placed over a force platform, the subjects stepped down onto an adjacent force platform. The force platforms (AMTI OR6–7; Advanced Mechanical Technologies Inc., Boston, MA) measured the contact forces between the foot and the ground. A five-camera, three-dimensional, motion-analysis system (Vicon 250; Oxford Metric Ltd., Oxford, UK) was used to simultaneously record body segment kinematics as participants completed each step down.
Three block heights were used, equating to those of a curb (7.5 cm), a stair riser (15.0 cm), and stepping from the bus (22.0 cm)—obstacles frequently encountered in lifestyle. 24 Blocks were made of medium-density fiberboard of 1 1.8-cm thickness, which were bonded together to make a solid block with standing area 46.4 × 50.8 cm. Each block was covered with colored vinyl material that matched the surrounding floor.
