What is the function of a knee-ankle-foot orthosis (KAFO)?

The function of a knee-ankle-foot orthosis (KAFO) is fundamentally to stabilize and support the knee and ankle joints, in addition to the foot. This device is typically prescribed for individuals with conditions that impair muscle control, strength, or coordination in the lower limbs. By providing structural support, the KAFO helps to maintain proper alignment during movement and aids in functional mobility.

This stabilization is particularly essential for individuals who may experience weakness or instability in their lower extremities due to neurological conditions, musculoskeletal disorders, or after injuries. The design of the KAFO enables it to limit excessive motion that could lead to further injury while enhancing the safety and mobility of the user. The support it offers at the knee, ankle, and foot allows for better control during ambulation and activities of daily living.

While improving flexibility, correcting posture, and providing cushioning are important aspects of rehabilitation and care for many patients, they do not represent the core function of the KAFO. This orthosis is specifically focused on joint stabilization and support, which is critical for individuals requiring assistance with weight-bearing and mobility.
