Which K-level corresponds to a household ambulator?

K1 is classified as the appropriate K-level for an individual who is a household ambulator. This classification signifies that the person has the ability to walk inside the home but does not possess the capability to walk outside of the home or participate in community ambulation. Therefore, K1 typically indicates minimal mobility, primarily limited to activities such as getting around in the house.

In contrast, K2 is designated for individuals who can walk with the assistance of a gait aid, such as a walker or cane, but can only ambulate in limited community settings. K3 represents a higher level of mobility, where an individual can walk at a speed sufficient for community ambulation and engage in more varied activities. K4 is reserved for those who have the capacity for high-level activities and are often athletes or active individuals.

Understanding these distinctions is crucial for selecting the appropriate prosthetic device that aligns with the functional abilities of the user.
