pronációs

Pronação refers to the inward rolling motion of the foot during the gait cycle. It is a natural and necessary component of walking and running, allowing the foot to absorb shock and adapt to uneven surfaces. When the foot strikes the ground, the arch flattens and the ankle rolls inward, a process known as pronation. This movement is primarily controlled by the muscles and ligaments of the foot and ankle.

There are different degrees of pronation. Neutral pronation is considered ideal, where the foot rolls inward a moderate amount, providing good shock absorption and stability. Overpronation occurs when the foot rolls inward excessively. This can lead to increased stress on the foot, ankle, and even the knees and hips, potentially contributing to conditions like plantar fasciitis, shin splints, and knee pain. Supination, also known as underpronation, is the opposite motion, where the foot rolls outward excessively. This can result in less shock absorption and increased pressure on the outer edges of the foot.

Factors such as foot structure (e.g., flat feet or high arches), genetics, muscle imbalances, and footwear can influence an individual's pronation pattern. Understanding one's pronation is often important in selecting appropriate footwear and in the treatment of biomechanical issues related to the feet and lower limbs. Gait analysis, which involves observing the mechanics of walking or running, is commonly used to assess pronation.
