What does the term 'supination' refer to in biomechanics?

Supination in biomechanics specifically refers to the outward rolling motion of the foot during normal activities such as walking or running. This motion occurs as the weight shifts towards the outside of the foot, often leading to the heel lifting off the ground slightly. Supination is a critical concept to understand, especially when assessing foot mechanics, as it affects how forces are distributed through the foot and leg during movement.

This term is important in the context of pedorthics and biomechanics since excessive supination can lead to a variety of issues, such as increased risk of ankle sprains, and can be involved in conditions related to overuse injuries. Understanding the dynamics of supination allows practitioners to better tailor footwear and orthotic solutions for their patients, ultimately contributing to better overall comfort and biomechanics.
