• Description:
  An inverted pendulum (IP) model of human gait can be used to understand the interplay between gravity and joint powers in propulsion. Dynamic walking models have shown that human-like gait can be achieved on downward slopes through gravity alone; yet, additional sources of propulsion are needed for level gait. Such an analytical finding was supported by inverse dynamics of a telescoping IP directly applied to normal gait. Here, pendulum radial kinematics (telescoping) improved the prediction of both horizontal and vertical ground reaction forces (GRF). Without telescoping, GRF predictions deviated significantly from actual values, during sagittal power bursts at the hip, knee, and ankle joints. We hypothesized that these findings would extend to patients with hemiplegic cerebral palsy, despite a range of mobility disabilities and prior treatment. [Description provided by NIOSH]
