Ankle Angle Contribute to Slip During Commercial Kitchen Activity

ABSTRACT

@#Introduction: Working in a Commercial kitchen environment poses a potential hazard for a slip accident. Prolonged standing working posture reflects human balance issues. Therefore, this study investigated the ankle angle during Commercial kitchen activity to justify the potential of slip during the activity and correlate between the walking step and slip incident. Method: Vicon motion capture was used to record movements and Vicon Nexus software was used to analyze data. Six male and six female healthy adults with a minimum of three years of Commercial kitchen activity experience participated in this study. Participants have to walk at four different speeds and carry the load at the upper limb and flooring with water and oil as a contaminant. Results: The slip occurred frequently on the oily surfaces compared to water surfaces especially among overweight and obese participants. Ankle angle during slip occurrence was from 97.2 ± 6.7° for male participants and 112.5 ± 12.7° for female participants. Conclusion: The results presented that overweight and obese participants' significant slip occurred when walking on oily surfaces. There was no correlation between carrying load and Body Mass Index (BMI). The walking speed also significant with slip occurrence.
