    Abstract

    We propose a knee instability detector for standing using two uni-axial accelerometers, tangentially placed on the upper leg. This detector may be used as a part of the finite state artificial reflex control strategy for paraplegic standing with minimal quadriceps stimulation, as proposed by Mulder et al. [l - 21. The detection strategy was experimentally tested in two healthy subjects. Detection on the basis of accelerometer data appeared to be faster than with knee goniometer data. Furthermore, accelerometers may be preferable because they are small and do not cross the knee joint, like in the case of conventional goniometers.
