“…A concurrent inversion moment has been observed during gait in healthy individuals as well as those using an ankle-foot orthosis [67–70]. Although a goal of this on-going research is to restore plantarflexion or dorsiflexion with absent or balanced inversion and eversion, physiological data suggest that it may not be necessary.…”

Problem Addressed Electrical stimulation has been shown effective in restoring basic lower extremity motor function in individuals with paralysis. We tested the hypothesis that a Flat Interface Nerve Electrode (FINE) placed around the human tibial or common peroneal nerve above the knee can selectively activate each of the most important muscles these nerves innervate for use in a neuroprosthesis to control ankle motion. Methodology During intraoperative trials involving three subjects, an 8-contact FINE was placed around the tibial and/or common peroneal nerve, proximal to the popliteal fossa. The FINE’s ability to selectively recruit muscles innervated by these nerves was assessed. Data were used to estimate the potential to restore active plantarflexion or dorsiflexion while balancing inversion and eversion using a biomechanical simulation. Results, Significance, and Potential Impact With minimal spillover to non-targets, at least three of the four targets in the tibial nerve, including two of the three muscles constituting the triceps surae were independently and selectively recruited in all subjects. As acceptable levels of spillover increased, recruitment of the target muscles increased. Selective activation of muscles innervated by the peroneal nerve was more challenging. Estimated joint moments suggests that plantarflexion sufficient for propulsion during stance phase of gait and dorsiflexion sufficient to prevent foot drop during swing can be achieved, accompanied by a small but tolerable inversion or eversion moment.

“…In the main fixation, a screw was generally used to link the tibial component and bone rather than cement ( Figure 4) 22 . Yamaguchi et al 23 measured in vivo kinematics of these prostheses (two-component TAA) and assessed the congruency of the articular surface during the stance phase of gait. They found that the range of sagittal rotation was maintained during the stance phase of gait after this TAA implantation; however, the axial and coronal rotations were less than those of the natural ankle 23 .…”
