In this article we present a compact and modular device designed to allow a conventional stiff servo actuator to be easily upgraded into a series elastic actuator (SEA). This is a low cost, open source and open hardware solution including mechanical CAD drawings, circuit schematics, board designs and firmware code. We present a complete overview of the project as well as a case study where we s...

Although manipulation under anesthesia (MUA) has been considered effective first-line treatment for stiff total knee arthroplasty (TKA), there is no consensus regarding the usefulness of repeated MUA. The purpose of this study was to investigate the usefulness of repeated MUA performed for patients in whom satisfactory range of motion (ROM) was not achieved by MUA. The authors retrospectively r...

BACKGROUND Pseudoaneurysm of superior lateral genicular artery following total knee arthroplasty is a rare complication and has been reported following lateral release performed for eversion of patella in a knee with tight lateral structures. CASE PRESENTATION This report describes a case of pseudo aneurysm of superior lateral geniculate artery that developed after primary Total knee arthropl...

INTRODUCTION Rigid Ankle-Foot Orthoses (AFOs) are commonly prescribed to counteract excessive knee flexion during the stance phase of gait in children with cerebral palsy (CP). While rigid AFOs may normalize knee kinematics and kinetics effectively, it has the disadvantage of impeding push-off power. A spring-like AFO may enhance push-off power, which may come at the cost of reducing the knee f...

We argue that there are three coherent, nontrivial notions of basic-ness: conceptual basic-ness, biological basic-ness, and psychological basic-ness. There is considerable evidence for conceptually basic emotion categories (e.g., “anger,” “fear”). These categories do not designate biologically basic emotions, but some forms of anger, fear, and so on that are biologically basic in a sense we wil...
