Which of the following is a common type of orthotic device?

An ankle-foot orthosis (AFO) is a common type of orthotic device designed to support the ankle and foot. It is typically used to manage conditions that affect lower limb function, such as weakness, instability, or deformities. The AFO helps to maintain proper alignment, provides stability during ambulation, and assists in walking by controlling motion at the ankle joint.

The versatility of AFOs allows them to be customized according to individual patient needs, which can include adjustments for different ankle positions or levels of support. This customization is crucial for rehabilitation purposes, making the AFO an essential tool in orthopedic and rehabilitation settings. Its widespread use in treating a variety of conditions, including stroke, multiple sclerosis, and cerebral palsy, further solidifies its status as a common and effective orthotic device.
