Which gait pattern corresponds to toe touch weight bearing (TTWB)?

The correct choice reflects the definition of toe touch weight bearing (TTWB), which is a specific movement strategy used in rehabilitation. When a patient is prescribed TTWB, they are instructed to make contact with the ground using only their toes, without applying any significant weight through that limb.

This gait pattern allows the patient to maintain some sense of balance and stability while minimizing pressure on the affected limb. The purpose of this approach is often to encourage mobility while protecting an injury or surgical site. It is important to emphasize that while toes may lightly touch the ground for support, the majority of the body weight remains on the uninjured limb or assistive devices.

In contrast, the other options describe different weight-bearing statuses that do not align with the principles of toe touch weight bearing, such as placing full weight on a limb or using both crutches for support, which indicates a different level of weight bearing entirely. Hence, the nature of TTWB restricts weight to the toes only, making it a unique and crucial aspect of rehabilitation protocols.
