Abstract
Children with hemiplegic cerebral palsy exhibit diminished motor control, range-of-motion, and strength, not only of the affected lower extremity (Winters Type I, II, III), but also of the ipsilateral upper body (Type IV). Involvement may be slight (foot drop in swing), moderate (equinus throughout the gait cycle affecting the knee and hip), and severe (additional coronal and transverse plane anomalies). An inverted pendulum (IP) model of gait can be used to understand the role of gravity in propulsion, within a framework of biomechanical studies of human movement, particularly, joint power patterns [3]. Forward dynamic simulations of an IP, applied to normal gait during single support, demonstrated predictive value for gait velocities and horizontal ground reaction forces (GRF), but not for vertical GRF. We hypothesized that these findings would extend to patients with hemiplegic cerebral palsy, despite a range of mobility disabilities and prior treatment.
