Abstrakt		In Part I, we proposed an approach for restoring unsupported standing to thoracic-level paraplegics. The theoretical analysis and simulation of an underactuated double inverted pendulum, representing the standing subject, showed that arm-free standing might be achieved. Here in Part II, we present the mechanical apparatus which we used in our experiments and experimental results from tests of the balancecontrol strategy. We demonstrate that an intact and a paraplegic subject could perform quiet standing with the ankle stiffness set to 8 Nm/° or even less (the intact subject). Both were also able to recover from disturbances, imposed by the artificial ankle joint of the apparatps. Introducing cognitive auditory feedback greatly improved the standing abilities of both subjects.
