Which type of prosthetic feet provides stability during the early stance phase?

The types of prosthetic feet designed for stability during the early stance phase are particularly important for enabling the user to have a secure and steady experience when walking. SACH (Solid Ankle Cushion Heel) feet are an excellent choice for this purpose.

SACH feet feature a solid structure that allows for a stable heel strike, absorbing impact and providing immediate ground contact. The cushion heel design helps with shock absorption and promotes a controlled transition from heel strike to flat foot, which is crucial during the early stance phase. Additionally, since SACH feet have a limited range of motion, they prevent excessive foot movement, contributing to overall balance and stability.

In contrast, other types of prosthetic feet, such as dynamic response and flexible keel feet, are often designed for energy return and propulsion rather than providing maximum stability during the early stance phase. Single-axis feet allow for some movement but do not offer the same level of stability as SACH feet. Therefore, SACH feet are the optimal choice for stability during this critical phase of the gait cycle.
