【 摘 要 】

Category:Midfoot/ForefootIntroduction/Purpose:Single-limb heel rise (HR) is used to evaluate muscle performance and clinical outcomes in people with foot and ankle pathology. While the midfoot contributes 13% of total foot/ankle work to forward propulsion during gait, healthy HR performance remains primarily characterized by ankle function. Similar to its function during gait, the midfoot may also generate power during HR to provide the stability needed for ankle push-off power. Further characterization of HR performance by evaluating midfoot kinetics may advance understanding of foot function in the clinical application of the HR task. The purpose of this study was to examine ankle and midfoot power and work during single-limb HR in healthy adults.Methods:Twelve healthy adults [Mean (SD): Age 31.3 (4.9) years; BMI 25.2 (3.3) Kg/m2; 50% male] performed twenty barefoot single-limb heel rises. Multi-segment kinematic and ground reaction force data were recorded with an electromagnetic motion capture system ...
