Which orthosis is MOST appropriate for a patient exhibiting a steppage gait?

1. Ankle-foot orthosis (AFO)

2. Knee-ankle-foot orthosis (KAFO)

3. Wrist-hand orthosis (WHO)

4. Foot orthotic

The correct answer is: Ankle-foot orthosis (AFO)

A steppage gait is characterized by a high knee lift and foot drop, which often results in dragging of the foot and can lead to trip hazards. The primary goal when addressing a steppage gait is to provide support that will help the patient maintain a more functional and safe walking pattern. An ankle-foot orthosis (AFO) is specifically designed to stabilize the ankle and foot. It provides dorsiflexion support, preventing the foot from dropping during the swing phase of walking. This stabilization is crucial for individuals with foot drop, as it allows for better clearance of the foot during movement. By incorporating an AFO, the patient is more likely to achieve a normal gait pattern and reduce fall risk. In contrast, the knee-ankle-foot orthosis (KAFO) offers support at the knee as well as the ankle and foot, but it may be unnecessarily restrictive for a patient whose primary issue lies with ankle stabilization. The wrist-hand orthosis (WHO) and foot orthotic do not address the specific requirements for managing a steppage gait, as they are designed for different parts of the body and have different functional purposes.
