OPORP Trial Design

2Treatment groups
Active Control
Group I: Proprio FootActive Control1 Intervention
microprocessor-controlled prosthesis that regulates the angle of ankle dorsiflexion during the swing phase
Group II: Empower AnkleActive Control1 Intervention
a powered prosthesis that provides active propulsion in late stance to mimic the positive work performed by the ankle plantar-flexors in push-off. The Empower has been shown to improve affected leg kinematics (increased ankle range of motion and reduced knee flexion) on smooth flat ground, ramp ascent, and gravel
