To begin the test, use the dowel to measure the height of the tibial tuberosity. Since it can be difficult to find the truejoint line between the tibia and the femur, the top center of the tibial tuberosity serves as a reliable landmark.To adjust the previously described hurdle to the correct height, have the client stand with feet together and use thedowel to measure from the floor to the height of the top and center of the tibial tuberosity. Slide the hurdle’s markingcord to the tibial tuberosity height measured, and adjust the other side until the cord is level and displays accurate tibialtuberosity height on both indicators.Have the client stand directly behind the center of the hurdle base, feet touching at both heels and toes and with thetoes aligned and touching the base of the hurdle. Position the dowel across the shoulders, below the neck. Ask the clientto step over the hurdle to touch the heel to the floor while maintaining a tall spine, and then return the moving leg to thestarting position. The hurdle step is performed slowly and under control. Do not manually manipulate set up positions,but absolutely spot for safety and be aware of possible balance issues that could put the person being screened at risk.If any of the criteria for a score of three are not achieved, the client receives a score of two. If any of the criteria for thescore of two are not achieved, score this a one.
