TL;DR: A new method for estimating knee joint flexion/extension angles from segment acceleration and angular velocity data is described, which uses a combination of Kalman filters and biomechanical constraints based on anatomical knowledge and does not make use of the earth's magnetic field.

TL;DR: The effects on sensation of a thin, high impedance electrode designed to reduce the non-uniformity of current distribution are described.

TL;DR: A finite element (FE) model is described to predict skin current density distribution in the region of the electrode during stimulation and its application to the identification of electrode properties that may act to reduce sensation.

TL;DR: The results suggest that the ShefStim system with automated setup produces results which are comparable with clinician setup of conventional systems, and the final study demonstrated that patients can use the system without clinical supervision.

TL;DR: This paper describes a series of research and clinical studies which have led to the first demonstration of unsupervised automated setup of an electrode-array based drop foot stimulator.
