Stance Control Orthoses vs. Conventional KAFOs:
Stance Control Orthoses differ from Conventional KAFOs in that they allow for knee flexion during the swing phase and locking during stance phase.
Why Stance Control?
A traditional KAFO can lock the knee in full extension, which provides stability but also causes patients to ambulate with a gait deviation that can lead to overuse injuries due to compensatory measures taken by the patient to ambulate. This in turn requires more energy to get from point A to point B.
A stance control orthosis (SCO) allows the knee to bend during the swing phase of the gait cycle and blocks knee flexion for stability during the stance phase. By allowing the knee to bend during swing phase, SCOs allow a more normal gait, which may reduce secondary complications from gait compensations, and allow the patient to walk with less effort.
Benefits of SCOs over Conventional KAFOs:
Decreased gait anomalies during swing phase
Decreased pulmonary/cardiac stress
Esthetic gait pattern
