Centennial Honors College Western Illinois University Undergraduate Research Day 2014 Poster Presentation An analysis of Spatio-temporal Gait Kinematics for Three Types of Footwear Nadia Barrera Faculty Mentor: Tamara Bories Kinesiology The objective of this study is to analyze whether or not gait patterns change while wearing different types of footwear. One participant performed two walking trials while wearing athletic shoes, high heeled shoes, and flat soled shoes. She walked a total distance of 17 meters, with three meters at the start allotted for an acceleration phase and two meters at the end for deceleration. The participant was filmed wearing lightreflecting markers on their toe, heel, and ankle. The film was later digitized to quantify the gait speed, step length, and step cadence while wearing each type of shoe. Gait speed was measured by recording the amount of time it took the participant to walk 12 meters. Step length was calculated by measuring the distance between right and left heel contact with the ground. Step cadence was calculated by recording the amount of steps per minute. Analysis of the results shows that spatio-temporal patterns in the flat shoe and athletic shoe were similar but differed when wearing the high heel shoes. Knowledge of how different footwear leads to adapting gait patterns will help identify changes in postural control that may result in falls or injury. Future research may investigate different heel heights in high heeled shoes to determine when and how changes in gait occur.
