Analysis of Step Length and Walking Speed in the Students with History of Ankle Injury: Walking Performance

The purpose of this study was to determine the analysis of stride length and walking speed in the walking gait of students who have ankle injuries. This study is analytical descriptive research with a one-shot case study design. The analysis through video recording of walking gait at 3 meters distance is analyzed using Kinovea software version 0.9.5. The total sample in this study used 27 people from students majoring in Elite Sports at Universitas Negeri Semarang who had an average age of 20 years and had historical injury by the physiotherapy data. This study's results indicated a significant difference between the stride length of people with a history of ankle injury and normal people. It was found that the results of the length of steps and the walking speed of students with a history of ankle injury averaged 1.22 m shorter than normal, which is 1.73 m in stride length. The data found the average speed was 1.135 (m/s) faster than ordinary people who get 1.59 m/s. Limitations in this study are only kinematic data was analyzed and need more kinetics data to complement the founding of this study. Further research is expected to be able to analyze walking gait at each angle in the leg segment which has contributed to improving walking performance.
