Which physical sign indicates supination during an examination?

• A. Dorsiflexion of the toes
• B. Heel inversion
• C. Midfoot collapse
• D. Internal rotation of the tibia

Answer: (B)

The sign that indicates supination during an examination is heel inversion. Supination is a movement that occurs in the foot when it rolls outward, leading to an upward movement of the heel towards the midline of the body. This can be observed as the heel turns inward, creating a heel inversion. This position is commonly associated with conditions where there is excessive supination, which can lead to various foot issues and affect the overall biomechanics of walking and running. In contrast, dorsiflexion of the toes typically indicates other foot movements or positions but does not directly reflect supination. Midfoot collapse suggests a flatfoot condition, which would be the opposite of supination, indicating over-pronation or flatfoot alignment. Internal rotation of the tibia relates to movements at the knee rather than the foot's inversion or position, making it unrelated to identifying supination specifically. Therefore, heel inversion serves as the definitive sign of supination during an examination.
