MODEL-BASED IMAGE-MATCHING KINEMATICS ANALYSIS OF THREE ANKLE SUPINATION SPRAIN INJURY CASES IN SPORTS
Keywords: ankle sprain, injury biomechanics, video analysis
AbstractAnkle sprain is one of the most common injuries encountered at sport events. Three ankle supination sprain cases from high jump, tennis and hockey were chosen for analysis. Model-Based Image-Matching (MBIM) technique was implemented for reconstructing 3D ankle joint kinematics. The profiles of ankle joint kinematics were outputted from the selected sprain cases. The maximum inversion angle ranged from 78° to 142°. Plantarflexion was again found to be not necessary in ankle supination sprain injury. The results from the MBIM technique would contribute to the understanding of biomechanical injury mechanism of ankle supination sprain injury in sports. The future direction is to analyze more cases to consolidate the findings.
